Mayor Laufenburger: I'd just make a comment that to all those of you that are in the chamber as well as may be watching at home, visitor presentation is a great opportunity for anyone to come to speak to the City Council. You are invited to speak on any topic again that's not on the agenda. We welcome comments about anything. Things that are going on in your neighborhood. Things that you want to complain about. Things that you want to reward the city staff about. Anything and visitor presentation is a great time to do that so at this time we'll move to our next item on the agenda which is new business. 1630 LAKE LUCY ROAD: APPROVE REZONING FROM RURAL RESIDENTIAL DISTRICT (RR) TO SINGLE FAMILY RESIDENTIAL DISTRICT (RSF). AND PRELID4IINARY PLAT WITH VARIANCES FOR A 12 LOT SUBDIVISION ON 8.96 ACRES OF PROPERTY LOCATED AT 1600 AND 1630 LAKE LUCY ROAD. APPLICANT: YOSEMITE HOLDINGS LLC. OWNER: ALMOND & CAROLYN KRUEGER AND CRAIG & DEANNA CLAYBAUGH. Mayor Laufenburger: Do we have a staff report? Kate Aanenson: Yes we do. Thank you Mayor, members of City Council. Mayor Laufenburger: Good evening Ms. Aanenson. Nice to have you here tonight. Kate Aanenson: Thank you. As you stated this application is for subdivision with some variances and a rezoning. Just to give you some background on this. This item did appear before the Planning Commission on their May 17`s meeting. Issues of concern that were brought by the Planning Commission and those speaking at the public hearing included grading, stormwater management and tree preservation. Specifically there was concern about water and the grading around Lots 6 through 9 and I'll address that a little bit more specifically. We've asked for a condition, or added a condition on that regarding that they not be walkouts but rather be lookouts that would help with that issue. In addition we note in here that there should be additional analysis on some of the issues raised at the Planning Commission which the applicants are working on. All those conditions are reflected in the staff report as we move to final plat. As a reminder all the conditions that are in this staff report are the marching orders that the applicant needs to resolve before this item comes back for final plat and typically those items, or that application for final plat would be on your consent agenda. So in addition besides the lots on the from full basement ramble type homes, we believe that will help reduce some of the excessive grading in those areas. We also believe that the stormwater management plan shall, is required to reduce and does accomplish the 90 percent for total suspension solids and 60 percent of the phosphorus using the industry accepted removal rates. In addition there was a lot of discussion on tree removal as in the City's policy and I'll go through that in a little bit more detail. Tree Chanhassen City Council 4-1une 13, 2016 • preservation opportunities. We want to make sure that we're not putting trees where they try to preserve trees where a homeowner will take them out in the future so we try to do an overall plan and I'll go through that in a little bit more detail. So there was a pretty robust discussion with the Planning Commission and the residents that attended that public hearing but the Planning Commission did recommend approval at that meeting so with that I'll go through a little bit more specifics on the project. So the project is located on Lake Lucy Road and Yosemite. It actually includes 3 parcels. Two of them owned by the Krueger's and one by the Claybaugh's. The Claybaugh's house goes back to 1961 so it's been there quite a while and seen a lot of change in the area as Mr. Claybaugh stated at the Planning Commission meeting. In addition the Krueger's have 2 parcels so it's a total of just under 9 acres of property. As stated in the staff report we always calculate net and gross density in a project so that'd be on the first page of your staff report but the gross density is 1.33 units an acre or net 1.88 units an acre so again very consistent with what we would see with a traditional subdivision. So the project does require rezoning from Rural Residential to Residential Single Family and I'd just like to take a couple of minutes to go through when we looked at for the zoning options on the property. Again when the property is zoned, guided low density there's different zoning options that you could put into place. You could do a PUD. You could do a low, a twin home project and so looking at the correct application for a zoning district the staff did an analysis of that and looking at again the 3 or 4 different types of zoning. The PUD requires preservation of significant natural features as does the residential low and medium density and you'll see that in an application next week. The low medium density or the twin homes so again looking at the surrounding neighborhood and what would be the appropriate land use recommendation for that we selected that and the applicant also went for the RSF which is our most traditional single family zoning application. So that requires a 15,000 square foot minimum lots which all these lots meet or exceed that and then would be a more traditional subdivision application. Mayor Laufenburger: So Ms. Aanenson 15,000 square feet that's 3 lots per acre, is that approximately correct? Kate Aanenson: Yes, yeah and so it's a little bit more than that with all the calculations, correct. Mayor Laufenburger: Yep. Kate Aanenson: So that would be the zoning. Again that is consistent with the Comprehensive Plan as required so we are recommending that again, so those two things are consistent. So then with the application itself we look at the preliminary plat once we've figured out the correct application for the zoning. So within the low density as I explained there's 12 lots being proposed and 1 outlot so in looking at those there are some challenges here and we talked about that here and I'll let the city engineer go through those in a little bit greater detail but this plan reflects the previous application. The applicant has been working towards to resolve some of these issues and well on their way to doing that but we like to stick with the application that went to the Planning Commission and those modifications just to make sure that we're not, it's kind of not a moving target so they've got clear direction on what they need to get to final plat but these 7 Chanhassen City Council June 13, 2016 • were the issues that were raised at the Planning Commission regarding drainage coming around these lots. Being pinched against this retaining wall and coming out so we believe we've resolved those issues. We've also pushed 11 and 12 to get a greater setback between the wetlands so this would be out of the preservation area up between this outlot on the north side of Lot 12. So the variances on here are for use of the flag lots. We have flag lots in other places in the city. For example a subdivision immediately to the east. There's flag lots in that. There are some other flag lots on Yosemite. We have done flag lots and they are permitted by city ordinance. One of the issues that comes up on the flag lots is when they're stacked. When you have someone's back to rear but these flag lots all have front facing lots. Have good access. They're not stacked in such a way that someone's, so you have two side yards here. There's not someone with the rear yard to the back. Because they all exceed the 15, you can see these are 18 and 19,000. The ones that would be the furthest back still felt that they met the intent and would support the variance for the flag lots on those applications. Mayor Laufenburger: Ms. Aanenson. Kate Aanenson: Yes. Mayor Laufenburger: Just for a second. Could you just, you're using a term that perhaps some people may not be familiar with. Kate Aanenson: Sure. Mayor Laufenburger: Can you just describe what does flag lot mean. Kate Aanenson: Yes thank you for that opportunity to clarify that. So typically a lot has to have 90 feet of frontage on a street. In this circumstance it meets the 90 feet of frontage at this point rather than at the street. So while that meets all those standards and this is included in, is not included in the lot area. The lot is significantly large enough but it just doesn't have the frontage on the public street. Mayor Laufenburger: So we use that definition to provide people with ample building footprint and yeah land for building. We use that term to describe the matter in which it can be built even though it doesn't have 90 feet of street frontage, is that correct? Kate Aanenson: Correct. Correct. Mayor Laufenburger: Okay. Kate Aanenson: So on page 18 of the staff report we go into details of the rational basis then for the variance. That it meets the criteria as stated in Section 18-22 of City Code so we believe that based on the development patterns in here, the 2 large wetlands and because the lots are all of standard size that we believe that it meets the intent and would support that variance. In addition Chanhassen City Council qune 13, 2016 • engineering had a variance on the location of the separation from Lake Lucy Road and the entrance to this. Certainly less desirable to have access off of Lake Lucy Road itself; a minor collector there or coming up through the wetland which would have been the other choice so there would have been greater impact. So based on that we just felt that the best location for the street to go into the property would be at this location again because it doesn't have the 300 foot separation that is also a variance which the staff is supporting. The grading, I'll let the city engineer take a few minutes to go through the grading and some of the stormwater issues. Mayor Laufenburger: Mr. Oehme. Paul Oehme: So thank you Mayor, City Council members. As Ms. Aanenson had indicated most of the development is going to he mass graded. 'There are most of the properties are going to be lookouts. A portion of the property does flow to the south. There is a culvert that runs under Lake Lucy Road to the south. That drainage area is being reduced from I think it was 3.7 acres down to 2.3 acres so one of the improvements that we're trying to make or things that we're trying to address is to try to at least match or reduce the amount of volumes and rates that go to the south as much as we can. The grades, we've worked with the developer on the grades in this development a lot. It is a tight site and a lot of topography out here to work with but I think the grading plan that we did come up with is the best that fits this site and meets the needs of the development. The grade is shown here again. The development is outlined up here. Like I said the culvert that does flow under Lake Lucy Road flows through a, kind of a wetland system down to Lake Lucy. There are some culverts through a driveway that have been impacted by some larger rain events in the past. That's why we're being mindful and receptive in trying to reduce the amount of volume and drainage that goes through this system as much as we can. The utilities in this area are being serviced by city sewer and water. The sewer is going to be extended across Yosemite Road. A section of sewer was recently put in with I think the Glaccum just to the east of here. The sewer is fairly shallow in some areas and we are anticipating that a few of the properties would have to have some sort of internal grinder system to facilitate the sewer to be discharged into the city system. However it's, the system or the plan being proposed is a lot better than just having a large lift station for the entire development. It's more cost effective to do it this way than to put in a large lift station. We also planning for potentially future development to the west here. There are I think 2 properties to the west of the proposed development that are currently unsewered at this time. If and when those properties were to develop or if their septic system fails they have another option to service their property, sewer their property through the city system. Water is being extended through Lake Lucy Road through our trunk main there so that's consistent with what has been approved in the comp plan. Let's see drainage I think, I'll just talk on drainage real quickly again too. So I briefly talked about we're trying to keep the rates and volumes to the south at or pre -development condition. The rest of the water drainage off the site from the roadway and from the front yards is going to be directed into a bioswale here along Lot 10 to be infiltrated and treated prior to discharging into the wetland so most of the treatment will be taking place in this area. We did get updated drainage calcs from the developer's engineer last Thursday I believe. We just haven't had time to run through all the calculations and review that information at this time but we anticipate L9 Chanhassen City Council• ne 13, 2016 • having a full review by the end of the week here. Most of the, so all the drainage off the back yards here from Lot 9 through 10, there's going to be discharge into this wetland here. I think there's some bioswales along this section of the wetland here that will be infiltrated. There is a culvert off the cul-de-sac that will also be handled with infiltration and rate control through a swale here as well. It's more or less a rain garden. There will be a new culvert on Lake Lucy Road that will be constructed as well. The one that's out there today is failing so with that if there's any other questions with utilities. Otherwise move on with the landscaping. Mayor Laufenburger: Can you just back up for a second? Mr. Oehme you use the term, you said I think I remember these numbers. You said you're reducing drainage from 3.7 to 2.3 is that right? Paul Oehme: Yeah 2.63. Mayor Laufenburger: 2.63? Paul Oehme: So it's about an acre's worth of decrease. Mayor Laufenburger: So and that, can you go back one slide? One more. Paul Oehme: There you go. Mayor Laufenburger: So what your impacting is the drainage that goes under Lake Lucy Road is that correct? Paul Oehme: That's correct, right. So we try to reduce as much of the drainage area going to the south as much as we can and redirect it into the city system here into the bioswale here and into the wetlands to be treated. Mayor Laufenburger: So the wetlands, that term bioswale, that water will go into the city stormwater, is that correct? Paul Oehme: Yeah so it would go into the storm sewer system that's in, underneath the street here and then be treated in this area here mainly. Mayor Laufenburger: Okay, alright. Thank you Mr. Oehme, now you can continue. Kate Aanenson: Again just to be clear that, so these was the recommendation that these be changed from walkouts to lookouts. Mayor Laufenburger: To lookouts. 10 Chanhassen City Council qune 13, 2016 • Kate Aanenson: Yep and that was a lot of discussion at the Planning Commission, these walls and then the force of the water here so those are some significant changes that had been recommended. Mayor Laufenburger: And Ms. Aanenson are those conditions? Kate Aanenson: They're conditions yes so when you see the final plat those changes will be made. Mayor Laufenburger: Okay, alright. Kate Aanenson: Yep. Again a lot of discussion was on regarding the landscaping. How many trees we placed on there. This plan as shown here does not meet the canopy coverage. The applicant will submit a plan to meet that. There was a lot of discussion. Could they get all I I I trees on this site. Whether that's plus or minus. The City does have a policy if you can't put them on site then you can bank those credits and then they would applied somewhere else. Somewhere else in the area so that's the other option so that will all be worked out as a part of this development. Mayor Laufenburger: Again that's a condition right? Kate Aanenson: That is a condition of approval, correct. So again they need to put additional buffering in there and canopy coverage and so there's a mechanism to handle that if, there was a lot of discussion on whether or not that many can be placed on. I also want to clarify or just reiterate a couple other things that you know we do require 25 or maximum 25 percent hard cover. The building plans, pads that are shown on here are maximum showing the setback area so that doesn't mean every house is going to be that large and so typically what we ask for is a 60 by 60. These are larger. I think they're like 70 by 70 or 70 by so significant. They're showing the setback area so they still have to meet the 25 percent. That doesn't mean these can be, the houses will be as big as this square. It's just illustratively showing where the house can be placed within that square if that makes sense. Mayor Laufenburger: So Ms, Aanenson I'm glad you brought that up, the 25 percent. So if, if the footprints of the buildings were built as they're shown does this entire area meet 25 percent? The hard surface. Kate Aanenson: Yeah I haven't calculated that because it depends on what the house will come in. I doubt that it would, it might be close yeah. Yeah so we check each house plan that comes in. We would check the setbacks and we also check the hard cover calculations for each lot. Mayor Laufenburger: So every lot has to meet that 25 percent? Kate Aanenson: Every lot has to meet that one. 11 F Chanhassen City Council•June 13, 2016 • Mayor Laufenburger: So if one lot is 24 the additional 1 percent can't balance over into the other neighbor? Kate Aanenson: That's correct. Mayor Laufenburger: Okay. Councilwoman Tjornhom I think you were about to ask something. Councilwoman Tjornhom: I have, yeah I need to go back and when you talk about the total number of trees to be planted, the 111. 66 showing. I'm having a hard time figuring out, they need to plant I I I trees. Why is it 11 I? Why is that magic number? Kate Aanenson: Sure, yep. So the calculation is based on the upland area which is 7.3 acres and they have a baseline canopy which is about 65 percent of the area. It's got currently has canopy cover so the way our ordinance works is you have to maintain a percentage of that. It's assumed that with any developments some trees are going to be removed so if there's a significant portion of those removed then you'll have to replace it that much so the minimum canopy coverage required is 46 percent and they're proposing a 14 percent coverage so in the staff report on page 15 the detail by the City Forester outlines what the difference would be and that would be calculated by a percentage of square footage or caliper and that would equate to approximately 66 additional trees that would need to be shown. Or 66 are shown and they need I I I so again going back to again the Planning Commission got into a lot of detail on this too. Again the house plan might not be that big. There could be room for other trees on there or if it doesn't make sense there then we would bank some of those but again there'll be some additional trees up in this area for, we look at some of the extraction for some of the wetland there too so. Councilwoman Tjornhom: Because I guess I'm just having a hard time with the fact that you know our ordinance states, our City Forester has arranged or calculated that you know I I I trees should be planted there or. Kate Aanenson: Sure. Councilwoman Tjornhom: But if they can't do it and they can only put 66 in, I guess I'm having a hard time figuring out why they still have to buy the extra 30, whatever it would be trees. Kate Aanenson: Because they're taking that many down. It's the removal, yeah. It's the removal of the existing tree canopy and I think that was one of the issues that the neighbors had so, that they were concerned about so many trees going down because right now part of those lots are heavily wooded so they're tried to make that up so again following ordinance calculations that's how we do it. Mayor Laufenburger: Mr. Gerhardt did you want to say something? 12 Chanhassen City Councilqune 13, 2016 • Todd Gerhardt: No. Kate I think covered it. It's based on ordinance is how the calculation is drawn up. We do a tree inventory of all the existing trees and based on that inventory and the percentages in the ordinance it came up to be 111. We will work with the applicant to find another spot to plant the other 35. Councilwoman Tjornhom: But it won't be on this property. Kate Aanenson: It may not be. Again they need to do some revision to their landscaping plan. They are working on that right now. Again so some of their buffer requirements are along Lake Lucy. Some buffer requirements there. There's overstory/understory trees so it depends on the mix so. Councilwoman Tjornhom: Because well I understand that. I just would hate to make a developer go through extra expense of buying and planting more trees elsewhere if it just was impossible for him to follow the ordinance and our calculations. Kate Aanenson: Right and I think our goal is to make this a good project that meets some of the concerns that the neighbor had of getting reforestation back and following the city code so understand your point. Another thing I didn't cover while I think about it now. In the Planning Commission or the council update, the beginning we did have some additional attachments. The letters. I just want to make sure that the letters from Mr. and Mrs. Weingart and from Mrs. Randall and then some of the staff comments. The applicant's comments back and then I handed out to you tonight a letter from Mr. McCourt and then a phone conversation with Cathy Lam. Some of the concerns that they had. Again. Mayor Laufenburger: And Ms. Aanenson. Kate Aanenson: If you wanted me to address any of those I could do that now. Mayor Laufenburger: Yeah did any of these most recent comments, did they introduce things that were not discussed at the Planning Commission? Or was it a reaffirmation? Kate Aanenson: I think most of them, you know I think some of the comments from the Planning Commission meeting was as we know infill development. Change. Mayor Laufenburger: Yeah. Kate Aanenson: We talked about again I've been here 25 years. There's been a lot of development along Lake Lucy Road over the years. Shadowmere. Willow Ridge. Some of those projects have come in. It changes. These are 2 larger lots. I think the water quality issues certainly and the notification of a hearing notice that we always try to put a sign up. That one we didn't hear before. And then flyers, 350 feet is the state law. We do 500 feet and I think this applicant or this person sent it, a letter was over 1,000 feet away so we do our best. 13 Chanhassen City Council lune 13, 2016 • Mayor Laufenburger: Okay. And in many cases we exceed what's required is that correct Ms. Aanenson? Kate Aanenson: Absolutely, yes. Yes. Mayor Laufenburger: Okay, alrigbt. Continue with your presentation. Kate Aanenson: Sure, yep. So landscaping is still in the works and then finally this park, the Project is next to Pheasant Hill Park so we certainly wanted the applicant to find a way to integrate to the park. We know a lot of people walk along Lake Lucy. Dog walk and going to the Pheasant Hill Park so this is the applicant's drawing of a connection to the park. You can see this trail coming out into the park and that gets interpreted as you look at this connection here coming through and then we'll have a sidewalk along this street and then a connection back down to Lake Lucy Road. Again allowing people to walk down there to get to the bus stop and the like, or to use the trail to get to the park. A loop for other people in the neighborhood to use this and make their way around that. Mayor Laufenburger: Ms. Aanenson does that then become an easement for that trail or not? Kate Aanenson: It's a sidewalk and then this would be a trail easement I believe. Yeah, the rest of it would be sidewalk. Public. Mayor Laufenburger: Okay. Kate Aanenson: So with that the Planning Commission recommended to the City Council that you rezone the property from Rural Residential and then approve the preliminary plats and then also the variances for the flag lots and the cul-de-sac bubble and the 300 feet and then with the conditions of approval and adopts the Findings of Fact. With that I'd be happy to answer any questions that you may have. Mayor Laufenburger: Alright, are you going to leave this motion up here for just a second Ms. Aanenson? Kate Aanenson: Absolutely. Mayor Laufenburger: Alright. In just a moment I'm going to ask the applicant to come forward if you'd like, he or she would like to say anything but before we do that are there any questions of council for staff? Councilwoman Tjornhom. Councilwoman Tjornhom: I'm going to go back to landscaping again. It just, it's bothering me so I need to understand it more. That's 45 extra trees if I did my math right that we're going to make the applicant purchase and plant elsewhere. Is that correct? 14 Chanhassen City Council�une 13, 2016 • Kate Aanenson: Okay first of all I think we need to note that we did calculations and since that time there's been revisions to the grading plan, some of the site plan so we're saying that they've not been reflected in the tree preservation so we're asking them that they need to resubmit their calculations and we'll review that and compare that to the city ordinance. We're not asking, they're not asking for relief from the ordinance nor are we granting relief from the tree preservation ordinance. We're treating this project like we've treated everyone and the City's policy in the ordinance says if they can't replace them all on site, then they would bank those trees. That number, whatever that equates to and caliper to the City and whether we put it somewhere else along that streetscape or find somewhere else in the park, something like that is how we would use those. Councilwoman Tjornhom: And so, and is that then I mean because we have categories of trees, shrubs and. Kate Aanenson: Correct. Councilwoman Tjornhom: So is that actual trees or would that be a mix? I mean. Kate Aanenson: It's a mix. It's a mix. Councilwoman Tjornhom: It seems like a huge expense that they can't invest into their development. Kate Aanenson: Sure and all I can say at this point is you'll have that opportunity to look at that at final plat because I think we're looking through those revisions so I would just hold that in abeyance until we see that at final plat and have a better idea of what those actual numbers are and how they're going to manage that, if that's acceptable. Mayor Laufenburger: Did you have another question councilwoman? Councilwoman Tjornhom: Tbat's it. Mayor Laufenburger: Mr. Campion you have a question, comment? Councilman Campion: Ms. Aanenson can you talk a little bit more about the variance request for the flag lots? Kate Aanenson: Sure. Councilman Campion: We have an ordinance for flag lots right? Kate Aanenson: Yes we do. 15 Chanhassen City Counci•une 13, 2016 • Councilman Campion: So then the necessity for the variance is what again? Kate Aanenson: Well it's pinched by the shape of the lot. The 2 wetlands here and because all of the lots are in well excess of 15,000 square feet. It wasn't like they were right at 15, 15, 15. It's just the shape of that. Trying to get this cul-de-sac to pinch. You can see these lots are deeper too so it's, if you look at Shadowmere, that subdivision... the site, I mean they also used flag lots and there's some other ones up on Yosemite too. We do allow flag lots via variance. The reason we changed it, it used to be standard that we could do it. We changed it to variance because the issue became when you have a, sometimes you see a flag lot with a lot in front and then a long driveway going behind and sometimes that's less desirable for the neighbors behind because they don't have the same orientation in the back so if you have a long deep lot and you want to split the back half of it, those became problematic. We saw this because they're all getting access from the same street, the same bubble and it doesn't have that same negative impact so we felt that we could support the variances on these. Councilman Campion: Okay. Mayor Laufenburger: And related to that Ms. Aanenson it appears that Lots 9 and 10 will share a common driveway until it comes to their property. Kate Aanenson: Correct. Mayor Laufenburger: Is that correct? Does that make sense? Kate Aanenson: (Yes). Mayor Laufenburger: Okay, alright. And the developer's clearly aware of the requirements of the flag lots? Kate Aanenson: That's correct. Mayor Laufenburger: Okay, alright. Any other question of staff? Okay. Is the applicant present and would you like to address the council? State your name and address please for the record. Terry Forbord: Mr. Mayor, members of the City Council, my name is Terry Forbord with Forbord Land Company. I'm a principle with Yosemite Holdings and it's a privilege to be before you this evening. We're very grateful for the extra effort that the staff has exhibited in this very challenging exercise of trying to find the best possible development scenario for an infill piece of property within the city and they've done an excellent job. We support their recommendations. In the, due to my respect of your time and your agenda we can be as extensive with the presentation this evening on my background. Roger Humphrey my senior 16 Chanhassen City Council Tune 13, 2016 is engineer is here to answer any questions but out of respect for your time rather than bore you with a history about my work in Chanhassen I'd prefer to leave that question to you. I would like to thank you for recognizing Senator Ortman. I've known her for a long time too and she's done a great service to this community and the state. I have had a privilege of developing 6 communities in Chanhassen. All of them occurred during the 90's and early 2000's. That would have been Longacres, Willow Ridge, Springfield, Highlands at Lake St. Joe. I directed development at Near Mountain and it was a privilege working with the City then and it is today. Mayor Laufenburger: Your thumbprint is everywhere Mr. Forbord. Terry Forbord: Well. Mayor Laufenburger: Well not everywhere but substantial. Terry Forbord: It's very important to make sure that people understand is that I had an incredible team of people working with me. It wasn't just me but it was a real privilege to build these wonderful neighborhood communities in Chanhassen and it's fun to be back here again. But we're here to answer any questions that you might have about this so please feel free to raise anything. Mayor Laufenburger: Okay, anybody have a question for the applicant? I do Mr. Forbord. Are you familiar with the conditions that City staff is putting on the development? Terry Forbord: Absolutely. Mayor Laufenburger: And are you prepared to comply with all of those conditions? Terry Forbord: Yes we are working with them. Since the Planning Commission we've been working daily with the City on each and every one of those things including the trees. The site plan, as Community Development Director Aanenson mentioned has, this is the original submittal and we've been going through some reiterations to make it better since then and the tree planting and everything ultimately then will change as well and we know that those are conditions of this, of the final plat and so we're fully prepared to do that. Mayor Laufenburger: Okay. Alright. Thank you Mr. Forbord and Mr. Humphrey for being with us tonight. Thank you for making yourself available. Terry Forbord: Thank you. Mayor Laufenburger: Ms. Aanenson let's come back to you for just one question. Can you bring the motion up please? So I've heard you say, we'll get it there. Kate Aanenson: Sony. 17 Chanhassen City Council une 13, 2016 Mayor Laufenburger: That's okay, I'll be patient. Kate Aanenson: I remember we had a mouse there. Mayor Laufenburger: 'There. So I heard you say that in some form a few times that we're working towards getting to that condition and you use the terms that it will come before us in the final plat. So if we were to move forward with approving this tonight this item will come back to us again is that correct? Kate Aanenson: That's correct. Mayor Laufenburger: Can you explain to, especially to those people that are with us this evening, what does that mean? We're giving approval for a next step but what does the council, what authority does the council have at the final plat approval? Kate Aanenson: Well your authority lies in the conditions that you put in there. They have to show that they've met all those conditions and there's a pretty lengthy list. As the applicant has stated they're working on those right now. We've been seeing those back and forth so they have to meet all those conditions. Mayor Laufenburger: Okay. And this is very customary for us in developments like this is that correct? Kate Aanenson: That's correct. Mayor Laufenburger: Okay, that we see a preliminary plat and it's that time that the council hears about conditions that have been stipulated. Not necessarily met but will be met at the time of the final plat. Kate Aanenson: That's correct. Mayor Laufenburger: Okay, ahight. With that said is there any comment or any questions or comment from the council? Anybody. Is there anybody that would like to make a motion? Todd Gerhardt: Mayor do you want to...? Mayor Laufenburger: Oh excuse me. Thank you Mr. Gerhardt. Thanks for the reminder. I mentioned earlier in the meeting that all members of the council were present with exception of Councilwoman Ryan. She has asked me to read this letter in her absence and I'll read it word for word. Dear Chanhassen residents and neighbors. I've asked the Mayor to read this letter on my behalf. I deeply regret that I am unable to attend tonight's meeting but unfortunately I have been struggling with some health issues this past week which caused me to spend some time in the 1E Chanhassen City Council Tune 13, 2016 • hospital. I am hopeful and optimistic for a full recovery. The Lake Lucy Road subdivision proposal is one that has been a topic of much discussion. Like all proposals this is an important one but it's also one that directly impacts my surrounding neighbors. Please know that my concerns have been expressed and noted and I know your emails, your calls and conversations will also be taken into careful consideration when the City Council makes it's decision this evening. To all residents please continue to reach out to council with questions, comments and concerns as it is a very important part of the process. Again my apologies to you for my absence in representing your voices tonight. Councilwoman Elise Ryan. And I would just simply echo what Councilwoman Ryan said in her note that this proposal has been in front of the council for a number of days now and we anticipated it's coming forward so we have reviewed Planning Commission comments. We have reviewed correspondence. We have reviewed comments from citizens given both personally, face to face. Phone calls. Emails, et cetera so we have considered all of this and we also consider the importance of the conditions that are stipulated in the proposal as well. So with that is there anyone that would like to make a motion? Councilman McDonald: Mr. Mayor I have a question. So the motion that's up is not the motion that's in the packet. Which motion do you want to use? This is from the Planning Commission. The one in the packet is for. Todd Gerhardt: Kate? The City Council motion. The one up on the screen for Planning Commission. Kate Aanenson: It says, oh okay. Sorry. Just take this off. Councilman McDonald: Okay. Kate Aanenson: You can take the Planning Commission word off, yeah. Councilman McDonald: Well it's a little bit different also. It talks about the bubble lot or the bubble circle. Kate Aanenson: Yeah you can read the motion in the packet. It covers all the conditions of approval plus adoption of Findings of Fact. Mayor Laufenburger: Okay for those present in the council, can you go back to the Planning Commission motion just for a second. Kate Aanenson: It reads the same. The problem is that this is in here. This is correct. Mayor Laufenburger: Okay, this is the right motion that's on the screen right now Mr. McDonald.

AND PRELIMINARY PLAT WITH VARIANCES FOR A 12 LOT SUBDIVISION ON 8.96 ACRES OF PROPERTY LOCATED AT 1600 AND 1630 LAKE LUCY ROAD. APPLICANT: YOSEMITE HOLDINGS LLC. OWNER: ALMOND & CAROLYN KRUEGER AND CRAIG & DEANNA CLAYBAUGH. Aller: For the record we have received several items to add to that package. One is a email from Renee Schubbe. A second from Alan and Mary Weingart and a third was a response to the staff recommendations to the preliminary plat filing by the respondent or the applicant and those items will be part of the package which goes to the City Council. We've had an opportunity, a brief opportunity to read it. My expectation would be that the developer will also review his responses to the recommendations when they have the opportunity to speak so with that we'll open up the hearing. Generous: Thank you Chairman Aller, commissioners. Planning Case 2016-09, Lake Lucy Road Subdivision. This is a public hearing. The applicant is Yosemite Holding Limited Liability Company. They're requesting a rezoning of the property from rural residential district to single family residential district and a preliminary plat approval review with variances and we'll go through those in conjunction with the subdivision. The property is located at the northwest comer of Lake Lucy Road and Yosemite Avenue. It consists of 3 properties or 3 parcels. Two are owned by the Krueger's and the other is by Claybaugh. Again these properties are currently zoned rural residential. They have 2 single family homes on the 3 properties. The total site is 8.96 acres. The property is guided in the Comprehensive Plan for residential low density uses. What this means is that densities of 1.2 to 4 units per acre are permitted on it and it all depends on the type of zoning that they are given that they determine the final outcome of that development. Rezoning from rural residential to single family residential and preliminary plat Chanhassen Planning Commission — May 17, 2016 with variances. The request, in looking at the rezoning of the property we had to determine which zoning categories are consistent with the residential low density land use designation. Single family residential is a primary zoning category that the City uses on residential low density properties in the community. Approximately 85 percent of our lands that are guided for low density are ultimately rezoned to RSF. A second zoning category that could be appropriate would be mixed low density residential. The R-4 district. This district permits both single family homes and twin homes on the development. Again this is a single family development so staff believes that that wasn't the appropriate zoning in this instance. The next consistent zoning would be low and medium density residential or RLM. Now this permits single family or attached housing. The one caveat we had in the RLM district is that the developer is to maintain a significant area of upland as common open space. In this instance we don't have that characteristic of the development. While they're preserving the northeast comer of the site it's mostly because of the wetlands that sort of restricted development of that part of the property. And finally a planned unit development residential would be consistent with the residential low density land use. However in that instance we're looking for either the provision of affordable housing or housing types that cannot be developed outside of a planned development and in this case they can meet all the requirements of the RSF district and so staff is recommending approval of the rezoning to RSF which is consistent with the land use designation. The proposed subdivision of the property would create 12 single family lots and 1 outlot which would contain the 2 wetlands and the preserved wooded area in the northeast corner of the development. Currently they designate Street A as the public street providing access into the development. And then this Street A would connect into Yosemite which is a collector roadway under the City's hierarchy of road systems. Lake Lucy Road is an arterial road and it's a road we're trying to take local access off of so that's part of the variance request is one of the reasons that we're looking at that. The 12 lots all exceed the minimum requirement for single family residential development. They are proposing the use of 3 neck lots. At one time neck lots were a permitted category or design standard. In the, I believe it's the late 90's the City amended the ordinance to make it a variance. We did this so that we could look at requiring specific orientation of structures so you didn't have people's front yards looking into rear yards or whatever the concern may be. Also we can limit size of driveways as part of that and the neck lots so that we can control the amount of impervious surface within the development. It also allows for consistent development patterns within a development. The right-of-way, yeah and these are the 3 neck lots within it. All the rest of them have the full minimum frontage on the public street. The variances requested in conjunction with the subdivision are for the use of the flag lots. The 3 that they're proposing. To have a cul-de-sac bubble less than the 60 foot radius and this is for Lot 11. You see how the cul-de-sac is offset to the east and because we have the full width it really cuts into this Lot 11 and if we're able to move that over farther we believe we can improve the stormwater capability of the stormwater pond which is located on the east side of the development. The other variance would be for setback from that right-of-way from, only from the cul-de-sac bubble for Lot 11 so in essence we'd be picking up 20 feet of buildable area in this area which would allow them to shift this over and this house over and potentially get more of this outlot area or green, easement area on the east side of Lot 12. The next one is for the 300 foot offset between street right-of-ways. In reviewing this development when it initially came in 2 Chanhassen Planning Commission —May 17, 2016 we looked at 3 different access points. One would come off of Lake Lucy Road which is an arterial roadway. The other was to push it farther north and come in between the wetlands. However we ruled out this consideration because it could have very negative impacts on both the wetlands on the property and would eliminate the preservation of the only viable wooded area that we had on the site. Finally because of the wetland this access location is forced south so we could not meet the 300 foot separation on Yosemite. And again if we had gone off of Lake Lucy Road that's an arterial. We're trying to remove access from directly from that so. Staff believes that this 300 foot offset. We did have the application do a queuing study to see if there's any back up issues for traffic that would make left turns into the development and there should not be. There's sufficient distance between the two. And I've already hit the building setback on, just on Lot I 1 from the cul-de-sac bulb. They would still need to maintain the 30 foot setback from the rest of the street right-of-way so this building line remains the same. This is the one that comes over approximately 20 feet and so staff is recommending approval of the subdivision with variances. And then we're going to tag team this and Alyson will address the infrastructure and grading issues on the project. Fauske: Thank you Bob. When the applicant first came to staff with the proposal for this development the driving factor, one of the driving factors for the design of the site was the sanitary sewer design. Sanitary sewer for this site is being extended from the Glaccum subdivision which is just to the east of this property. As you may recall it's, it was approved last year and they brought sewer in from across Lake Lucy Road to the Glaccum subdivision. Extended it to the west and under this proposal the applicant proposes to extend the sewer from that location within the Glaccum subdivision to their site. The challenge with that being is even though the sanitary sewer with the Glaccum subdivision was set as low as possible, it still it was not low enough to serve all of this site so the developer's engineer had a challenge in designing the site in order to try to get the sanitary sewer to service the lots and in fact in the staff report we've indicated that the sanitary sewer is actually shallower than we usually see it in order to try to get service to these lots so we've been working with the applicant. That was, like I said that was a driving factor on the site. One of the design considerations for this site. In conversations with the applicant's engineer as well when they were looking at the grading of this site, one of the desires of the developer was to balance the earthwork on this site meaning that they wanted to limit the amount of fill that would be brought into the site. I'll let them speak a little more to that if you have questions with regards to that but that was something that they had indicated to staff as well as far as trying to build the site up to get the gravity sewer as well as we've had some discussions with some of the building styles in particular over on the west side of the site. Lots 6 through 9. When we look at this the trail connection is high and then the grades dive down with drainage going to the back of the Lots 6 and 7, as well as here over on Lots 8 and 9. We had some conversations about that area. If there was an ability to alter that so that we could get a more level back yard and again I'll let the developer speak to that as far as what their constraints were with bringing that portion of the site up. And most of the grading, the grading portion of the staff report covers mostly pages 6, 8 and 9 of the staff report for those who may be following. As staff mentioned in the staff report, and just to what I had just touched on previously when staff looks at these drainage patterns here in the back yard they are close to the 3 Chanhassen Planning Commission — May 17, 2016 proposed building pad. Again the developer has indicated that the building pads shown on these sites are oversized. That the actual home styles would not utilize all of the building pad here. We understand that. We'd like to make mention of it though. Just as go through this process just to have it, just to have it out there as a concern. It's not, it doesn't make the lot unbuildable but with the drainage swale depending on how they place the home on the property utilizing that building pad that we've had feedback from residents when their back yard is encumbered by an easement. That's a concern for them because it limits what they can do to some extent in the back yard, as well as with the grades as well as any permanent structures within that easement so we like to bring that, we just like to note that in the staff report to say that these are things that we see. We've had discussions with the developer and they can, I'm sure they'll speak to the fact that like I said they have different building styles that wouldn't utilize the full building pad and how they site it on the site and they can talk about what the market is telling them what they would like to see and what their buyers are desiring now in this economic climate. Another discussion that we've had is with regards to the impervious surface coverage on a lot. When we start looking at particularly at some of these neck lots, again it's an oversized building pad so we just wanted to bring it, have that conversation. Make note of it in the staff report that depending on the house out there they might be approaching, they might be getting very close to the maximum impervious surface coverage. We like to note that. The developer had indicated that they would be doing some disclosures with the builder that they're looking at on the site to make sure that they're aware of the 25 percent standard. The desires, we don't want to be in a position where a building permit comes in and the home that they want to put on the lot simply doesn't fit given the impervious surface coverage restraints so these are all things that we like to earmark because it is such a challenging site. These challenges arise on a site like this so we just wanted to make note of that in the staff report. I haven't had a chance to go through the developer's comments that were submitted this afternoon in great detail. We had some conversations earlier today with the grading and the drainage to the south here and I just wanted to speak to that. I know we've had some correspondence distributed to the Planning Commission so I felt it would be prudent to go over what we're looking at for drainage to the south and again the developer's engineer is here to answer any questions that you might have with regards to that design. So when they were looking at this site there's a drainage treatment feature here and then they're looking at another feature here at the back of Lot 4 and somewhat into Lot 3 and 5 but this area right here and it's this area that drainage underneath Lake Lucy Road and to the properties to the south. We do have another slide that shows the pathway once it goes south of Lake Lucy Road but just wanted to go over a little bit of where we're at with the design of this system and doing the analysis on the existing to the proposed conditions. We want to make sure that, that what's being approved is feasible and that it's s something that will work long term. We want to make sure that the drainage, the grading plan shown here and the assumptions that were made in the drainage report are reasonable and ultimately that's how the drainage system will function so we've had conversations with the developer's engineer and will continue to do so as we move and refine that process. As I mentioned when we looked at that drainage feature on the south side of the site it drains underneath Lake Lucy Road. This green line here indicates the existing storm sewer that would convey that drainage to the south. And then there are a couple of driveway culverts on this property that extends to the island within Lake Lucy so it flows. It's a 4 Chanhassen Planning Commission — May 17, 2016 circuitous site, or pardon me. A circuitous route. It comes around through here and kind of winds down through here so as you can see it's a meandering path and the developer has designed the pond so that the rate and volume after development would not significant, would not increase. There's a little bit of tweaking for what we call the 10 year event. What you would expect to see once every 10 years so I feel confident that we can keep working with the developer to achieve that goal but that was one of the concerns and again a challenging site. One of the design parameters that staffs been working with the applicant on. Generous: Then landscaping. Actually I want to get back to, as part of this development there's a, the City reviews it under the tree preservation ordinance and what we do is initially establish what the total canopy coverage of the site is and so that comes out to be a percentage of the total development. And then our ordinance establishes targets for preservation of canopy coverage. Because we were aware that as part of any residential development you have to put in a public street. You're going to take out trees. You have to put in stormwater improvements so you're going to take out trees and so what the ordinance says if you can meet that target we won't penalize you. If you can't meet that target then you have to replace those trees you're taking out at a 1.2 to 1 basis so it gives us a numerical way of determining how many trees need to be planted as part of the subdivision. The initial landscaping plan submitted by the applicant showed 66 trees that are being replanted on the site. However based on staffs review and our tree preservation ordinance the applicant needs to provide I I I trees. Primarily we get it in the buffer yards along the streets and at least 1 tree per front yard. We believe as part of this development those extra trees will have to go into the revegetation of Outlot 1 and on the east side and maybe along some of the other perimeters in the project. Especially staffs concerned with the view from the house that's directly to the north of that. That they still have that more native feel on it but we'll work out that revised landscaping plan as part of the final plan submitted and the final plat application process. And of these trees 75 percent of them have to be an overstory type tree so they'll be larger trees. Eventually they'll revegetate the site and it will probably better species than are there now because there's a lot of boxelders and ash in place and so. With that staff is recommending approval of the rezoning of the property to single family residential and preliminary plat approval for 12 lots and 1 outlot and public right-of-way with variances for the use of the flag lots, cul-de-sac bubble size and local street center line offset of less than 300 feet and a building setback variance from the cul-de-sac for Lot 11 to permit a 20 foot setback from the right-of-way subject to the conditions of approval in the staff report and adoption of the Findings of Fact and Recommendation. With that I'd be happy to answer any questions. Aller: Anyone have any questions at this time of staff? Commissioner Weick. Weick: Give me a second. For the 300 foot variance, that's between Street A and Lake Lucy. What is the distance? That we're varying to. I couldn't find it. It's hard to read. They're blurry right. I'm an old guy. 5 Chanhassen Planning Commission — May 17, 2016 Fauske: Commissioner Weick if you wouldn't mind proceeding with some of your other questions and I'll take a look at that and provide you with an answer. Weick: Yep, that'd be great. And then the other question I have is in reference to the bubble. The cul-de-sac bubble variance. If you could explain that, exactly what that variance is asking again. Generous: Do you want to? Fauske: Certainly. Commissioner Weick I would be happy to answer that. Weick: Oh, I was hoping that was over here, sorry. Fauske: So through the design iterations on this site staff worked with the applicant. Originally there was, this feature was actually over on this side and we had a meeting and a discussion and got a larger feature moved over to this site and one of the concessions with moving the stormwater management feature to this site would be that, we would be willing to reduce the setback and the right-of-way requirement for the cul-de-sac bubble so that Lot 11 could be shifted further to the west and allow to accommodate in this. My understanding is that this plan doesn't necessarily show the reduced setback and I apologize if I'm incorrect in that. So there's still an opportunity to shift this further to the west and so we've included that in the recommendations to approve the variance understanding that we still have a little bit of the stormwater design work to finalize and so that if this feature needs to increase in size to the west, that the Planning Commission has already made a recommendation with regards to that variance so that it would be, that they could move forward with shifting Lot 11 further west. Weick: So we're not changing the diameter of the cul-de-sac then? Fauske: Correct. The actual street cul-de-sac diameter remains the same. It's the right-of-way that we're reducing correct. Weick: Thank you. Aller: Yep, Commissioner Tietz. Tietz: Yeah Bob and Alyson maybe, I don't know who I should direct the question to but it appears from looking at the topo map that the drainage basically breaks down from southwest to northeast. We have the greatest number of homes and lots in the southwest side but the capacity to hold water is all in the northeast side so I'm really concerned. My concern is about the overall drainage. Have there been calculations assuming a typical, if there is a typical home that would be built on this site, considering the hard surfaces for the house. The hard surfaces for proposed driveways. Hard surfaces for the roads. What percentage of the 8.96 acres is hard surface and it looks with the mass grading we're going to have severely compacted clay soils which have 0 Chanhassen Planning Commission — May 17, 2016 naturally been infiltration's been quite natural for the last probably 40 or 50 years. I just, what is the analysis and what's the impact? Fauske: Sure. I'd be happy to answer that question Commissioner Tietz. In the stormwater analysis what they've done is, they've taken a look and they developed the drainage area boundaries based on their proposed grading so with, in response to your question about splitting the drainage. What goes to the north and what goes to the south, the storm sewer catch basins within the street would capture the runoff from the street and place it to the north. So that, and the design, the grading design and the storm sewer design is such that the area going to this south basin would be, and I'm not accurately drawing them. I'm just going to show it representatively but, and I believe in the staff report there was an exhibit that shows the portion but a small portion of the back of Lot 6, through the side of back 5 and then looking at the house pads that they're showing on the grading plan, approximately 75 percent of the grading, of the building pad draining to the south to that pond. With regards to the question with the stormwater management and how they model this, the model includes what they call a curve number and a curve number assumes a certain amount of impervious surface on a residential lot so the assumptions that, the numbers that were placed in the report we agree with. It also takes into account the soil type so when we look at the current soil type and the proposed soil type, the current soil type as you had mentioned we've got, we've got some tree canopy coverage and some soils and one of the concerns that staff, that we've been talking about is getting that model to accurately reflect what the soil condition would be after construction because as you mentioned you're moving dirt around. You have equipment on there. It does get compacted. It has that higher potential for runoff and those are all components that can be added into a stormwater model. So as I mentioned we're very close on the runoff discharge rates and volumes and we just want to be sure that we're getting an accurate reflection of the soils after construction in that model. Tietz: Okay, good. Thanks. What's the frequency of 10 and 100 year storms in the last 10 years? Fauske: They've recently updated those numbers so it used to be a 100 year event in Chanhassen was 6 inches and I know it's increased. Each of the storm events have increased in the actual inches of rain based on what they've been monitoring in the area so that has changed and that's been reflected in the applicant's drainage calculations. Tietz: Okay. Yeah we see more frequency. All you have to do is look at Houston and look at Florida today. We're getting 6, 10, 20 inch storms. I don't think we're immune and we have to be able to address that and deal with it on all of our construction. Aller: Commissioner Madsen. Madsen: I believe this is directed to Alyson. There's a reference to a term that's a bounce of water. Could you clarify exactly what that means? 7 Chanhassen Planning Commission — May 17, 2016 Fauske: Certainly, I'd be happy to. I believe, is that with regards to, I know there was a resident that had some, had submitted a comment about the bounce. So that's a terminology that we use when you have a water level and I apologize to those at home that might not be able to see this. If we normally have a water level here, if it fluctuates up to this level that's what we call a bounce so as you've got runoff coming to that area you see a bounce or an increase elevation of that low area. That wetland. That pond and so that's what we refer to as a bounce. Madsen: Okay, thank you. Fauske: You're welcome. Aller: Additional questions at this time? Aanenson: Can I just add one other comment too. The reason why this wasn't on your last Planning Commission meeting is the deep dive that was done on the storm, managing stormwater. It's complex as Ms. Fauske just said. It's complex so we did spend a lot of time making sure that we got it as close as we could before we brought it to you. Is there some minor tweaking? Yes and a lot of that included instead of having drainage on either side of Lot 12. Combining it. Making that a better drainage and in that we agreed to compromise and move Lot I 1 over so there was just a lot of work done on that the last 2 or 3 weeks so. Tietz: Kate it may be hard to impose on development but you know we look at a lot of slow retention systems on all the commercial properties. How many times have we dealt with that in the last 6 months where something has come and we have a holding system that then releases or we have a system beneath a parking lot that slow release. You know if it's appropriate at some point and it's the only way to deal with downspout issues and driveway issues is it, it's probably not practical but should we be considering some type of homeowner retention systems to reduce the flow rate? Aanenson: Don't disagree. And then for this project you know it's infill which makes it more complex because the existing things, the developments around them were not built to those same standards so it's how do you balance, making this meet the standards where there's maybe some surrounding developments that weren't built to that standard so trying to make that work. We've talked about other ways to managing stormwater. Requiring that they keep it on site using it for potential re -use. Those are things that we're looking at as we move to the future but again on this project we worked really hard, engineering staff did working with the applicant to get, to make sure we were had this right because it is a concern to the property to the south, we understand that. Generous: Chairman Aller to answer Commissioner Weick's question, it's about 190 foot centerline offset. 190. 8 Chanhassen Planning Commission — May 17, 2016 Weick: Thank you. Madsen: I one more comment. Aller: Commissioner Madsen. Madsen: There's a comment in the report about leading the staff to conclude that it's unlikely that more water is not being directed south than is claimed. Can you tell me what you were able to study and what changes could be made to get you comfortable with the numbers so that water is not draining southward. Fauske: In the staff report I believe that's around page 8. One of the assumptions that I believe is, or that's discussed prior to that comment was with regards to getting the drain spouts on the building pads directed to the north and the challenge with that is now, is that we're now dictating for the homeowners how they're setting up their drain spouts. I think the applicant, if the applicant has some ideas to remedy the concern expressed in that comment. One of the things that you know I think they've talked about, and please correct me if I'm wrong, if there's a way that they could connect that drain spout to a system that is forced to direct it towards the street so that it's not just a drain pipe above ground but that there's a way that it's actually forced to go to the street but those are, that's the question. The other thing that we could do is if it's going to, if it's going to go to the south that the feature here on the south side is just sized appropriately to accommodate that and I would like the developer's engineer to be able to comment on that as he's, he's designed the site. Has the most knowledge of the site and can really speak to what some of the challenges are with regards to the drainage, specifically Lots 1 through 5. Madsen: Okay, thank you. Fauske: Thank you. Alley: Seeing no additional questions at this point in time for staff we'll go ahead and ask the applicant to come forward and make it's presentation at this time. Tent' Forbord: Good evening Mr. Chair, members of the Chanhassen Planning Commission. My name is Terry Forbord. That's F=o-r-b-o-r-d. It's my privilege to be here this evening and representing a couple families that are long tens Chanhassen residents of many decades. The Krueger family and the Claybaugh family. We were selected from a group of developers to represent them and to develop their property. I'd like to launch the power point if I can because I'll use it as a reference. If you could put it in slide format I'd appreciate it. Thank you very much. I represent Forbord Land Company. I'm the owner and principle. Oops, it's moving and I'm not touching anything. How do we do that? Okay there it is. I'll handle it from here if that's okay. Hemlock, excuse me. Yosemite Holdings is the Holding Company that we're using for the development of this subject property. As I mentioned I'm the principle with Forbord Land Company. I've been doing this for 39 years. I've developed well over 5,000 home sites in 0 Chanhassen Planning Commission — May 17, 2016 hundreds of subdivisions, primarily in Minnesota. Some in Colorado and some in Florida. I'm not going to go through a whole bunch of things about me because that really isn't what's important. There it goes again. It's moving. How do we get this so it goes one at a time? Fauske: I was going here and I apologize. Terry Forbord: Oh that's okay. So rather than talk about me and all the projects that we've done I'd like to focus just on the ones herein Chanhassen that some of you might be aware of. Some of you might live there. So if I could just get to that next page. And this is an exhibit that kind of displays those and those primarily I directed the development of these communities. Near Mountain, which is in the northeast corner of the city. Longacres which is on Highway 41. Willow Ridge. Willow Ridge is right down the street from this subject property. There's Springfield down in the southeastern portion of the community and then Highlands at Lake St. Joe is over on the western boundary. That represents hundreds of home sites. Those were all frankly done in the 90's and I was the President of a company called Lundgren Brothers Development at the time. Since that time I've developed, as I mentioned, thousands of other home sites around the metro area but what's more important is the ones in Chanhassen. I'm very fortunate to have very fond memories of former mayors and city council members and planning commissioners and Carver County commissioners and Met Council representatives because we all worked very hard to extend urban services to this area. As Mr. Tietz was mentioning it was all corn field back in the day. I also had the privilege of working with many of your staff members that are still with the City at this time. This subject property, it was referenced a moment ago that it's an infill site. Definitely this is an infill property. Being on the Planning Commission you're probably quite experienced with the fact that infill sites are always much more complicated than green field development. I can say honestly in my entire career I have never worked a site as complicated as this site. Ever. That doesn't mean that there were any particular individuals that were problematic or anything but there were on site and off site constraints. There were infrastructure constraints, et cetera, et cetera. The good news in that is, and it was just kind of touched upon a little bit but it's appropriate for me to say that there was a very unique process that we went through and part of it is due to my style but a good part of it is due to the style of the staff in the City of Chanhassen. I rarely, I just don't submit applications unless I've had countless meetings with the staff and we've all come to an agreement generally on what needs to be done in order for a development to proceed so we started that process in January and we've gone through probably no less than 20 reiterations of just the site plan for 12 lots. You've heard about the challenges about access. Ideally from a pure development point of view, pure development coming off Lake Lucy Road would have been the most efficient and effective way to do that. However it's I believe a minor arterial within the city and from that standpoint it wouldn't have made any sense. The next best pure development entrance would have come off of Yosemite from the north and that would have gone inbetween those 2 wetland complexes and from an efficiency and a development scenario that would have been the second best but what it amounted to though we would have had to clear cut a bunch of the trees in that wetland area which is now one large outlot and it would have forever changed the way that that piece of property would have looked from the streetscape so just like every other step of the way If, Chanhassen Planning Commission — May 17, 2016 we got together with staff and we started drawing various reiterations of how is the best way to do that. And like I said 20 concept plans later the most efficient and effective way to do that was what you're seeing this evening. Just a couple things that are still in play. We agree with everything in the staff report by and large except for maybe 4 things and tonight I'm not here to debate those with you and debate those with the staff. We've worked very closely on that. We just gave you a handout to make it part of the record. What we're going to do just like the staff has recommended approval there's all these conditions and in that report it says they're going to continue to work with the applicant prior to final plat to come to a conclusion on all those things and I'm confident that that will happen and so we're okay with that. Those 4 items that we put in front of you were just put in there for the record. We haven't had a chance to finalize all those discussions with the city staff but it's been a very interactive productive process and I'm grateful that we have a city staff that we can do that with. One thing that Alyson pointed out very well was that if we could get up the site plan if you have it easily in front of you. That area where she was talking about the biofilters. Could you point to that area? Now that area right there, about 3 or 4 reiterations ago there were 4 of those pre-treatment ponds on the site. Well we all know from a practical application to maintain those and repair them, whatever needs to be done if there's 4 small ones it's highly inefficient so we spent some time. How do we merge all those into one? Now ordinances are very important because they kind of create a framework for development to occur but sometimes when you look at environmental concerns or things like that you say you know what, the smartest thing we could do was to put all those biofilters into one outlot. That way it would be more efficient. It would be more effective and if we have to maintain it we have one access to it and they're just a far better way to do it so she talked about part of that process and it includes shifting Lot 11 and Lot 12 to the west. That space between there and the cul-de-sac bubble will shrink and they did that by putting like a 5 foot variance on the setback but what it's going to do from an environmental standpoint and efficiency standpoint, stormwater management is the right thing to do so that's the way this whole process has been and it's been very constructive. So I'm not going to go into a lot of detail about everything that has been accomplished to date because I believe it's actually been summarized quite well and memorialized quite well in the city staff report and we agree with it. The last thing that we'll do prior to addressing any questions that anybody might have is that Roger Humphrey my senior project engineer with Stantec who's with me this evening is just going to go over the handout with you just briefly but we would like to get into the public hearing component of this and address any questions. That's probably the most efficient use of our time but prior to me handing this over to Roger just to have him touch base on that handout is there any questions that the Planning Commission has of me? Aller: Anyone at this point in time? I'll just quickly address that. For purposes of the neighborhood what is your expected price point on these homes? What's the valuation that you're looking at? Do you think that this is going to have a good or bad negative impact on the pricing for the neighborhood? Terry Forbord: That what would have a negative impact? ]fl Chanhassen Planning Commission — May 17, 2016 Aller: I'm saying the fact that we're infilling the neighborhood, if you can. Terry Forbord: Yeah I'm very familiar with this area. I live 3 minutes away in Shorewood so I'm in this area all the time and have been for 35 years. I've watched all the development patterns and as you can see by the slide I've developed a lot of the home sites in the area. That's just in Chanhassen. I can see that the target market for new homes on this particular site will be in that $750,000 to $1.2 million. That's the range that will be there and I'm meeting with a number of builders. I'm close to selecting one builder which I'd much prefer to do. It's much easier for all parties to have one builder on a site like this but I think by, if you're familiar with the existing condition on the property vis a vis what we intend to do with it, I think it's a fair statement that it will be similar to the other new communities that have developed along Lake Lucy Road over the last 10 to 15 years. Aller: Alright. Terry Forbord: Any other questions? Tietz: Yeah I have a question. How did you arrive at the number of lots and what was the minimum number of lots and the maximum number of lots that you considered during this study period? Terry Forbord: Well frankly if you look at the Met Council requirements of the City of Chanhassen on the amount of units that are supposed to be in these various districts, from a pure math calculator standpoint there should be about 22 home sites on this site. However when you start, one thing that I learned a long time ago is that dirt is never in the right place. The roads are never in the right place. The trees are never in the right place. The wetlands are never in the right place and the pipe is never in the right place so once you take a site and even though your calculator tells you X, that you should be able to get 22 home sites, the shape and all the other aforementioned items change the developability of the property and so we had reiterations that went from I believe it was 11 to like 18 and we settled at 12 working through this process with the city staff. Tietz: And what were the critical site factors that influenced the design? Terry Forbord: The primary, there's two primary ones apart from trees, wetlands, those type of things. One is the sanitary sewer invert depth which completely was, is a huge factor. Secondly is the stormwater management limitations and so those items became very prevalent apart from trees, wetlands, topography, shape of the property, et cetera. Any other questions? Tietz: One more. Since you're the developer and not the contractor correct? You're going to select a contractor for the homes? Terry Forbord: Are you talking about the home builder? 12 Chanhassen Planning Commission — May 17, 2016 Tietz: The home builder yeah. So you're not the contractor for the homes? Terry Forbord: I'm a real estate developer and I work with home builders, correct. Tietz: So how do you, all the conditions that have been presented to you, how will those conditions be handed off to the home builder? And who's going to control that process? Terry Forbord: Well there's a couple ways to do that. I tend to like to do both ways. One is I memorialize those conditions in the purchase and sale agreement with the builder. It should be pointed out that I'm meeting with the builder now and I've gone over the staff report with the builder this week. We're very close. We do a lot of business together. We're friends so there's, they have a 45 day feasibility period in their agreement with me so they get a chance to go through all of that and they know as much about the project today as I know so, but we added as exhibits the conditions of approval are added as an exhibit to the purchase and sale agreement. In addition to that there will be a homeowners association for this property and items that are of importance become part of the CC&R's of the homeowners association. Items related to easements as Alyson mentioned, they become deed restrictions on the title so it's good to have multiple ways of memorializing important things to make sure that nobody says later on well nobody told me or nobody mentioned it. Even when you memorialize things like this 1,000 percent sometimes people say well nobody told me. I didn't read my title or I didn't read my purchase agreement. Those things happen but the best way you can do it is have as many ways as possible so nobody can say nobody gave me anything. So I hope that answers your question. Tietz: Thank you. Aanenson: If I could just add to that too. We did spend some time talking about that at staff. I mean it's not uncommon. That's a lot of how development's done these days. You have a developer then a builder so in this circumstance we talked in detail on some of these unique attributes to each lot and hard cover and all that so the person looking at that lot may know a certain type of home. How that hard cover, drainage issues, so those will all be spelled out by lot. We talked about that would be part of the final documents so we have tried to think through that issue too. Tietz: Okay, thanks Kate. Terry Forbord: And these issues that you brought up Commissioner Tietz are actually quite common these days. Sophisticated builders want to know very much all the detail about that. It's always important to, I personally I identify the builder as the conduit to the consumer and so it's important that the builder really understands those things and the builders that I work with do. They live and breathe this every single day. Tietz: Okay, thanks. 13 Chanhassen Planning Commission — May 17, 2016 Fauske: Chairman Aller? Aller: Yes. Fauske: If I may add onto that. In addition to Mr. Forbord's due diligence with the information he provides to the builder, the conditions of approval from a final plat are included in a development contract which is recorded against each lot within the subdivision so there again there's another way that a property or builder would be able to know all the conditions required with regards to this subdivision and that's true with other subdivisions that is brought forth to the Planning Commission as well. Aller: Thank you for the clarification. Terry Forbord: Thank you. At this time I'd like to turn the podium over to Mr. Humphrey, our project engineer. Aller: Welcome Mr. Humphrey. Roger Humphrey: My name's Roger Humphrey. I've been doing land development engineering for over 20 years. I have my own company for much of that. I joined Stantec somewhat recently as their senior land development engineer and been working closely with Terry and staff all the way back, I think we started designing this project in December and worked closely with staff through January, February and all the way through to where we are today and we, we're not showing you everything because there's a lot of information that went through in that design. Terry's right, I think we have 15 different concepts that we reviewed from various access points and we were initially settling on the access north of, in the north end of Yosemite between the two wetlands and I'm really glad to say that we were able to sit down with staff and actually work through that issue of doing a queuing design on the intersection and going down to less than the 300 foot offset. We had a neighborhood meeting back, I forget. April and we had a really good turnout and we listened to all the comments and one of the biggest comments was how beautiful the property looks coming from the north on Yosemite between the two wetlands and primarily that's the area we ended up saving and so we in our demolition plans and the building plans and everything that goes into the design we are able to create basically a protection zone all through that area and connect into two wetlands in terms of an environmental corridor between the two areas and I think that's a project success in the collaboration that we did working together. I'm going to touch a little bit on I guess our responses and comments, not too much. I think they're more intended to just kind of say that between us and staff I think we're working together very closely. I don't see any of these issues that's hard items. It's just that it's good for us to be able to communicate how we want to proceed and move forward on several of these items. I actually also think when we go through this process we often get a lot of conditions and we have 80 conditions through the thing and 76 of them in my opinion are and we're indicating it here are conditions that are standard and typical to final plats and we consider 14 Chanhassen Planning Commission — May 17, 2016 those are moving forward points in terms of advancing the project and advancing the design. In my experience I've never seen that ratio as high as saying we agree 76 out of 80 percent of the, or 80 times out of the whole condition and the remaining 4 items are generally minor in detail. What I would like to address because I've heard the concerns and I'll probably hear some more of it tonight as far as the drainage going to the south. The existing drainage area, and I'm wondering if you could pull up maybe not our stuff but the drainage plan that you guys had up previously. The drainage divide is really kind of from the southeast to the northwest and the area that's existing that goes to the south is 3.7 acres. And the proposed area that's going to the south is 2.44 acres and those are primarily just back yards of that development. I'm sorry probably the one that shows our plan. So it's only part of the lots from 1 through 5 that are actually going through there and the other kind of question or issue with, or discussion that's been having is we show building pads at I think 75 to 70 to, 70 by 70 as an average building pad out there. That's the maximum extent as a building zone and so the houses aren't that big and we have to meet the impervious surface requirements and we provided a chart to do so so that it's very clear on how big they can build on that but that can fit anywhere in that zone. And along with the developer's agreement that's recorded and all the conditions that are memorialized through the process, in addition to that one of the conditions on the building portion, item 4 of the building condition plans requires that to get a building permit they have to submit a final grading plan and that will show the dimensions. How it fits in relationship to all the other concerns that are addressed and that and I think that's a very important condition that we want to see happen as much as the City because that insures a quality and good project. The only other thing that might not have been touched about in the drainage aspect is that we have two wetlands on the north and primarily most of the water coming off the roadway is coming into the wetland to the east and we're putting a pipe under Yosemite Road that will allow the conveyance of any additional waters and items of that to provide lower high water marks and items of that nature and the City has a lot more capacity easements and other controls downstream in that area. Bob I wonder if you could go to the landscaping plan on your's too. And again I'm just trying to correlate some of the things that how we looked at our design and how we tried to accomplish these things. The buffer trees that we show along Yosemite and Lake Lucy down on the bottom of that screen, we understand that we need to plant more overstory trees and we need to accomplish that but just in our approach on the design is that that line is a series of overstory and understory trees so we have a tree here and a tree here and a tree here and so the idea is to create the screening that goes through in that process and that was basically our design approach and so we'd like to keep the integrity of some of those items as we go through and of course in this process of we design. We hand it off. We receive comments and back and forth, that communication process is I just wanted the Planning Commission to understand the background of what we were proposing. The last item and it is one of our conditions that we wanted the Planning Commission to be aware of is the requirement of removing all the trees from within the right-of-way that we're planting and we understand the concerns in terms of maintenance and things that go along with that process. We have from the front yard setback we have 30 feet and then we have a 15 foot boulevard so that gives about 45 feet of planting area in the front yards. If we take 10 feet away from the building side just because we can't build a, plant a tree really much closer than that and we take the 15 feet off the right-of-way all of a sudden we're down to about 20 feet which is less 15 Chanhassen Planning Commission — May 17, 2016 than half that zone and these will all become yard trees but it just seems in an aesthetic aspect that, whether we can take a consideration of having some of those trees be planted in the boulevard obviously set back from curbs and sidewalks in an appropriate manner but it just gives us more of an aesthetic aspect in the design of how the subdivision looks and is approached from that standpoint. But from that standpoint I'd like to thank everyone and if you have any questions for me I'm happy to answer them. Aller: Any questions at this time? Commissioner. Tietz: I have a question about the trees. Since that is a big concern and I'm not so, I shouldn't say I. I think screening a residential development from Lake Lucy may not be as important as providing canopy trees back into the development that you're creating and I'm just you know questioning staff and questioning the City whether there's a way to escrow or bank trees and as the development is constructed of putting trees back into those front yards and along that street so that you're recreating a canopy in an area that had canopy for many, many years as opposed to stuffing them along Lake Lucy. But it would, you know the site grading, you're grading, you're mass grading almost 70 percent of that site so putting trees in before construction starts I think they soon would become twigs and splinters but if there's a way and this may be a concept that's inappropriate but to consider banking those trees and having the developer put trees in after the fact. Aanenson: Just to be clear on the condition that we have, they're still short 45 trees. Tietz: I'm talking about the 110 trees you know. Aanenson: Sure, yeah. Right so what I'm saying the landscaping plan doesn't show the shortage of the trees so that's something that's not that uncommon that we've done in the past after the house gets placed so that's something we can run past the Forester. That's an issue the Planning Commission wants to look at. Tietz: It may be a way of dealing with the canopy issue and the understory issue and creating a more inviting neighborhood and increase the value of the neighborhood. Alley: It will also help the stormwater. Tietz: Pardon? Aller: It will also help with the stormwater. Tietz: Potentially yeah. Roger Humphrey: We spent a lot of time identifying the trees. Specifically a lot of the perimeter trees and one of the things we heard from the Planning Commission and I went out and 16 Chanhassen Planning Commission — May 17, 2016 looked at the site to, or after sorry. Our neighborhood meeting I went out after the site to just evaluate and look at the site as is from a standpoint of where these are and how the trees look and part of that was the entry coming in on the corner of Yosemite and Lake Lucy and as you turn that corner going north on Yosemite, straight ahead is a group of trees. They're fairly set back from the right-of-way and there's a fair amount of trees along Lake Lucy that as we kind of redid this new design I think those trees are being preserved through the process and we take our business very seriously and we are experienced in the design and layout and construction of these things and so I'm the guy that's out there with Terry. That's why when we had the neighborhood meeting and I heard what we heard it's an opportunity for us to get to know the neighbors and at the same time we can save trees potentially but also when they're in certain areas you know it's a risk factor to save them or not save them and I think we'll do our best in terms of preserving those as best as possible. In that corner intersection where we moved the watermain over. We moved some of the utilities out of the way. That gives us a better opportunity to save those trees as well. Thank you. Aller: Commissioner Madsen. Oh Mr. Humphrey, we have one more question Mr. Humphrey. Madsen: One of the conditions is that the runoff rates and volumes cannot be increased to the south. Could you just touch on how that will be accomplished? Roger Humphrey: Sure. Again that's why I kind of wanted to mention that. The primary means to that is limiting the area that goes to the south and we felt we did that. I think staff is, wanted to insure how we do that and I think as we move forward through the final plan portion of that. You know I see that as a very easy thing to do or to document that that water goes and where that dividing line happens to be. In addition to that the area that does go south is primarily the back yards of the homes and there's, these are longer, deeper lots and with our newer design there are areas that are undisturbed down in that lower area and we also have room to create stormwater ponding and devices that help control the rates and volumes of that and we believe that's appropriately sized and I think staff would agree with that size. I think the concern that staff has, or at least has put in their comment list is whether we can document the dividing line between that stormwater and I think we can do that so. Madsen: Okay, thank you. Roger Humphrey: Thank you. Aller: Alright, thank you. With that I will open the public hearing portion of the meeting and what will happen at this point in time is anyone wishing to speak either for or against the item before us, or has a comment to make can do so at this time. You would come up to the podium. State your name and address for the record and then let us know how you feel about the project. Any individual with us tonight wishing to come forward? 17 Chanhassen Planning Commission — May 17, 2016 Kim McReavy: Hi. I'm Kim McReavy. I live on Heather Court in Chanhassen. I was at the neighborhood meeting too because I'm concerned. I live near this area, although I'm not abutting it so I wasn't noticed or anything but I have a lot of friends who live in the area who are very concerned as well and they would have been here. They were supposed to come to the meeting 2 weeks ago and for some reason it was put off and I missed the beginning of the meeting. Maybe you explained why it was moved but they'll be at the council meeting so I walk by this area every day and there's a ton of wildlife on it. It's lovely. There's, I know they're going to take out 200 trees on it and I'm concerned with that and mainly because of what has happened across the street and I'm sure you've all noticed what's happened on, with the Weekley development on the comer of Yosemite and Lake Lucy. I think it's a travesty and the houses there I feel like really are cheapening the feel of Chanhassen in general. They look out of place. They're extremely close to the street. I really don't know how they're going to sell them but I guess that's not my problem but on a bigger issue for the City I'm concerned with this infill development that's happening. I don't think we need to fill in every single area in Chanhassen and as I drive down Lake Lucy and as I drive down Powers Road I just see lots of opportunities for this type of infill development where, and just because you can do it I don't think means you should so. For this development in particular I'm concerned about the loss of 200 trees. I know the developer was talking about nothing's ever in the right place. The wetlands aren't in the right place. The streets aren't in the right place. Well maybe if it's not in the right place then it's not the right place for this type of development and that's probably why it hasn't been developed yet so that is my concern too. I know that they were talking at one point about possibly tonight saving possibly some of the trees on the comer and I hope that if nothing else that can be accomplished, although at the neighborhood meeting they had pretty much said they were going to clear cut most of the property except for around the wetland which is delineated so that is my concern as a Chanhassen resident. I love living here. I know the developer has said that he loves Chanhassen too and has concerns with this area. Well I like Shorewood a lot too but I'm not really concerned as much as to what development is going on in there, you know as I'm sure the residents of Shorewood that live in the area are so as a resident that lives near that area and walks by it all the time I'm not in favor of this particular development so thank you very much. Aller: Thank you Ms. McReavy. Sir you said you want to come forward? Come on up and give your name and address for the record and let us know how you feel about the project. Andrew Hebert: My name is Andrew Hebert. The last name is spelled H-e-b-e-r-t and I live at 6566 Shadow Lane which is directly adjacent to that Glaccum Highlands development and it's because of that development I can said some things that I was going to that I wanted to attend here tonight. We just bought our house there herein Chanhassen just about a year ago and we knew the development was taking place. We had looked at plans and did a lot of research before buying the home. You know however what we've seen over the past year has really given me very little confidence that the plans will be followed and that the City or the developer or the builder really has the best interest in mind, you know the community's interest and the current residents interest in mind when they're making these decisions. You know the situation with my home is just one example but now I have a house literally right in the middle of my back yard 18 Chanhassen Planning Commission — May 17, 2016 view. You know maybe it's 10 feet from the property line. It's a different direction, layout entirely than what was on the drawing and so I've come to find out that a lot of these things that are talked about here at this stage they don't always get passed down to the builder and you know once it gets to that point it's just concerning that there's no controls in place to make sure you know we're looking for the interest of the people that already live here and so you know just watching everything take place from my back window, the destruction of all the trees. The impact on animals. Like Kim was saying, you know there's deer walking through there all the time. I used to see them. I never do anymore. And so that were some of the main things. I know with that development there were things like retaining walls and things like that that have not come to fruition as they were promised and I think they look bad. One thing I like about the area is the maturity of the trees and the homes and as someone coming from Eden Prairie that really appealed to me and so I feel like to just totally clear it out and regrade and do all these things is very risky and I don't think it's just a given that people are going to come and want to pay for that because it's, you know it's not the same place that you think of when you think of this area and so I think one of the problems as I've learned about the Glaccum Highlands development is that the builder is non -vocal and so I really wish I could have been you know more involved and the other, in that property because I think that maybe had something to do with it. I agree with Kim, I think the houses they look out of place. They look cheap you know and I just have not been happy with how it's gone and so I'm not opposed to development in general. I just think maybe there could be fewer homes and less of an environmental impact to help preserve the integrity of the community so thank you for the chance to say that. Aller: Thank you Mr. Hebert and welcome to the community. Andrew Hebert: Thank you. Aller: Any other individuals wishing to come forward? Please ma'am. Betsy Randall: Hello, my name is Betsy Randall. I'm at 1571 Lake Lucy Road. Directly across from this development. First of all I know the City has worked hard. The staff has worked great on this. I mean being really concerned about the water runoff and everything but I still have some concerns. There was a mention earlier in regards to if the ponding along Lake Lucy Road got to be too much that they might pump water or something onto Lake Lucy. Well there's nowhere for it to go. It goes right back down into my property or my neighbor's property and back through the cycle so I'm not sure how that would work. As I said the concern is the water issue and yes, looking at the 4 houses across Yosemite is not nice. I have been here 20 years. I moved all the way from Deephaven where I grew up. Love the area and as I said the City, the staff has worked hard on this I know. The rest of it I mean if they could cut down more houses that would be fine or fewer lots but I'm not sure that that's going to happen so that's my little piece. Aller: Thank you very much Ms. Randall. W Chanhassen Planning Commission — May 17, 2016 Betsy Randall: Thank you. Aller: Any other individuals at this time wishing to come forward? Sir come on up. Craig Claybaugh: My name's Craig Claybaugh. We live at 1630 Lake Lucy Road. Aller: Welcome sir. Craig Claybaugh: I served on the Planning Commission myself for 2 terms. I got used to people being resistant to change. Everybody is. The one constant is change. Al he moved in 1980. We've been here just about 25 years. I think Betsy I would guess she was therefor 40 plus years. That home was built in 1910. Just want to provide a little context. I understand it's change for everyone but when we moved in it was a dirt road. There was horses, 200 of them at the end of Lake Lucy Road. One by one they came in. Centex. Lundgren. And it was Robert Mason and Lecy so a lot of the properties we're talking about on Lake Lucy Road weren't here when we moved in so we've endured change. Mrs. Claybaugh: And we had horses. Craig Claybaugh: And we had horses. All those things needed to be forfeit over time to make room for the community to grow so it doesn't carry anymore weight than anything else. It just provides context so like I said we haven't been here 5 or 10 years. We've been 25 years. The reason the property wasn't developed is we raised our kids here. Our kids graduated from college. AI retired in December and it was time to make a life change. We selected Terry because far and away he's the best developer we could find. I worked with Kate for many years. I know her degree of due diligence. When they say they've done their work, they've done their work so just like that to be part of the record. Alley: Thank you. Anyone else wishing to come forward? Speak for or against. Yes ma'am. Charlotte Frerichs: I'm Charlotte Frerichs. I live at 6648 Lakeway Drive and I walk by this property every day and of course I'm grieving because I'm going to really miss the turkeys and the deer and the beautiful trees but I was very encouraged tonight to hear that the really the lovely trees right on the comer may actually be preserved but of course they have to be really careful that they don't damage the roots and there is a little retaining wall. There's a hillside that goes in that direction and I don't know exactly what they're going to do with that but if they take all that down I'm afraid it will damage the roots of those trees. And I might add also that that David Weekley property is really hideous and we're all really upset about it and I think that those retaining walls that are supposed to go by the wetland are so high, I don't know if any of you have driven by there but honestly if a child would fall they would be killed and they just put up a little teeny split rail fence there and I really think that the City should take a look at that. Thank you. 20 Chanhassen Planning Commission — May 17, 2016 Aller: Thank you for your comments. Roger Frerichs: I'm Roger Frerichs. The other half and also on Lakeway Drive and I just, we had a little question about this drainage. There will be more drainage I imagine than what there is right now down on the south, towards the south. There is you say a storm sewer down there already? Culvert going under Lake Lucy. Is that right? Fauske: Thank you Mr. Chair. Yes there's currently an outlet underneath Lake Lucy Road to the south. Roger Frerichs: And I just, the drawing shows a pond down there on the north side of Lake Lucy Road and that would be right adjacent to where the walking path is and is that a pond or is that just something that would pick up water in a rain storm? And then be drained out the next day. Because I think it would be a danger to have a pond of catchment of water down right on the south end of that. Aller: So are you talking about the water on the other side of Lake Lucy? Roger Frerichs: No right there where the pointer is. Aller: Oh up north. Roger Frerichs: And if that is, because the walking path is immediately between there and the road and you know people, kids go by all the time on bikes and people walk and I don't think we want any more water standing than we can avoid and so I didn't quite understand what that is. If that's a catchment basin that would drain immediately within the next 24 hours after a rain. Aller: Right. Roger Frerichs: So there's no standing water anticipated there. And I agree about the trees, that it's nice that there's some talk about probably being able to keep some of those trees but you know, and the comment about the roads, about everything being in the wrong place when development is being put in and I think we've got things kind of backward. I think we ought to try to fit the homes into the topography and that's not the current way developments are done. I mean more or less the development is regrading everything and everybody wants a lookout or a walkout so they grade it up in the front and they grade it down the back and you have no topsoil except what's put back but there ought to be more thought about putting homes in the right place for the land rather than changing the land so that it will fit as many homes as possible. Thank you. Aller: I appreciate your comments, thank you. Any other individual wishing to come forward at this time? 21 Chanhassen Planning Commission — May 17, 2016 Al Krueger: Hi. My name's Al Krueger. I'm part of this and I really bought my property in 1976. Moved in in the 80's or early 80's and yeah Craig's right. We used to go play with the horses that walked by so change is inevitable but the only thing I did want to mention, or that I wanted to bring up is the trees that are on the corner there are very dirty trees. Very, very dirty trees. They're dropping branches all the time. The roots are coming up and they're sprouting all the time and they're a tree that I think it looks beautiful in some sense. It's not an aspen tree as some people have called it so. And the trees, there's a couple nice trees that are on the property but 85 percent of them in 10 years, 5 years they're, it's going to look a whole lot better, let me tell you. As a single home resident who is not extremely wealthy I have to work very hard to try to keep those up and if you walk by there, as some of these people have noticed, there's trees falling down. They grow to the light and they're just going down all over the place but I too love the trees so thank you. Any other individuals wishing to come forward? Seeing no one, you sure? No one, I'll close the public hearing at this point in time and open it up for, based upon public comment. Any additional questions or comments of the commissioners? Canwe just, Alyson could you just talk about that water drainage system on the south side again just so that we're clear and what the jump was. That higher elevation and the impact on Lake Lucy Road if any. Fauske: Certainly. So with regards to, so the drainage pattern is, as you can see here, this is approximately the area where the biofilter basin would be. That takes that southern drainage area that we've been discussing. It would discharge into the existing storm sewer underneath Lake Lucy Road which is shown here in green to the south and from there the drainage pattern is shown here. It goes underneath a driveway. Winds back down. Goes underneath a driveway again. Through a low area here and then ultimately to the lake. I believe the area where we're speaking of the bounce is in this vicinity. I apologize I'm not exactly clear where that is but the bounce that they're referring to and hence the reason for not only requiring the post development discharge rate to be less than existing but the volume to be less than existing is that due to the grades in this area south of Lake Lucy Road where it would discharge to, is that there's no way for the area to outlet and therefore there would be a pooling of up to 5 feet of water before it would find an overland route to continue south and so hence the reason for no additional volume to the south. Aller: So with no additional volume you wouldn't have the bounce? Fauske: Correct. Aller: Or less bounce than we do today. Fauske: Correct, and so the staff report had that in there to again to memorialize how we've come about to the plan that's being presented and the reasons why and also to have, to memorialize that we've looked at the downstream impacts to the development. 22 Chanhassen Planning Commission —May 17, 2016 Aller: And the, just a quick follow up with the retaining walls. Retaining walls have been mentioned. All our retaining walls over 4 feet have to engineered. Fauske: Correct. Aller: And so any retaining walls here, those are conditions that are in the report and would be required of the developer. Fauske: That's correct. Any retaining wall over 4 feet has to be engineered and requires a building permit. Aller: Any additional questions? I think it was 4 wasn't it? Fauske: They've eliminated some from the time we first met with some of the plan iterations I think that's important to point out that we've had some benefit for example with having this drainage feature as Terry Forbord had mentioned combined into one system here. We actually, there was originally a retaining wall in this area so that one was eliminated. The other areas where there's retaining walls is proposed here between Lots 9 and 10 and then at the back here of Lot 9, at the back of Lot 8. Around here at Lot 6 and Lot 5 and that's, as you can appreciate with an infill development where you're meeting up to the grades of the adjacent properties, often times you do see retaining walls in the area. Tietz: I think it was stated that that Lots 1 through 5 will drain to the south but actually 7 and 6 drain around a 90 degree comer to the south too so you know there's, these retaining walls, you know hard edges are created because of the property boundary and it's not necessarily compatible with the adjacent property or the where the topography comes together. It's, you know there's several areas here that just seems to be really forced onto the site and I know that they studied 22 alternatives but you know it'd be a much more pleasing, if I were going to buy a three quarter of a million to a million two house, if you reduce those and put, you know look at 7, 6 and 7 together and 4 and 5 together you can mitigate retaining walls and change drainage and end up with 9 lots instead of 12 lots and up in the upper corner you can eliminate flag driveways. Three flag driveways you can eliminate. You can eliminate potentially reduce or minimize retaining walls and maintain your drainage patterns but reduce the number of lots and have a better merging of property lines. We have no idea what's going to happen to the west in the future. Aanenson: We did look at that. We provided access to those property to the north. There's 2 lots there. There's one is under 15 so it can't be further subdivided and the other one could potentially be subdivided. Probably just like in this process they'd have to, efficiency would be if they combine together. Likelihood of that because they're smaller you only get one additional lot. Less likely because you don't get the lot when you have the value of 2 homes to try to get one additional lot. Could the one lot come in and try to do a flag lot? That would also require a variance on that circumstance. We did look at that. 23 Chanhassen Planning Commission — May 17, 2016 Tietz: Did you look at, seriously look at eliminate flag lots? Aanenson: That's always an option. Tietz: Pardon? Aanenson: That's an option. Tietz: No but did you in the studies, were those studied to eliminate flag lots? There's 3. Aanenson: Correct. Correct. Terry Forbord: Mr. Chair? Aller: Yes please. Terry Forbord: Mr. Chair, members of the Planning Commission. Thank you. There's a lot of good dialogue and good questions happening from both the residents and on the Planning Commission. Eliminating home sites sometimes seems like a nonchalant cure in solving something but it would destroy the development. It wouldn't happen because of the economics. Notwithstanding all the very positive things that happen in a process like this, at the end of the day it's no different than the City's budget that they operate in day in and day out. They have to remain economically feasible and with a neighborhood community that we're creating here it also has to be economically feasible. The development cost per unit on this property is extraordinarily higher than a like kind green fill development in Chanhassen so elimination of any home sites would kill the deal. Aller: Thank you. Aanenson: Can I just go back to that point? Certainly the Planning Commission has discretion on how you want to respond to variance requests, whether you approve them or deny them. The staff had supported recommending approval but you certainly have discretion on that. Aller: Comments, questions? Commissioner Madsen. Madsen: There was mention of monitoring the water that might move southward after the development is completed. Who would be responsible for doing that and who would pay for it and how often would it occur if there was a suspicion that the volume had changed? Fauske: After a development is installed, I'll just back track one moment. I apologize. Through the development contract which we previously discussed at this meeting, the City takes a security for all the improvements installed with the development. Included in that is stormwater 24 Chanhassen Planning Commission — May 17, 2016 and after the developer's installed all the improvements the financial security that the City collects to insure that the project is installed per the approved plan, we release a portion, the majority of that security but we hold on to a portion of the storm sewer security for that very reason so for a 3 year period we're able to monitor the storm sewer system and insure that it's functioning so we do have, and I would, the reason we've chosen 3 years is you can, any anomalies in a dry year you can hopefully get through the next year and it will be an average year so that we can have a monitoring period to insure that it's installed per the plan and is functioning properly and hold the security to insure that any changes necessary to that system are completed. Madsen: Thank you. Fauske: You're welcome. Hokkanen: Can we talk about trees? Aller: Let's talk about trees. Overstory or understory? Hokkanen: The landscape plan is short 45 trees. Does the developer think they can place 45 more trees on there? Can we require them if it was to approve 2 front yard trees? I mean instead of 1. It doesn't even look like there's 1 front yard tree per lot. I mean that would help with stormwater management with the canopy. Anything? Aanenson: Alyson can you go over to the landscaping plan? Thank you. Yes, so one of the things we talked about is there's an Outlot A putting, excuse me Outlot 1. Putting some additional trees there and looking at that. That's something that we'd have our Forester look at. Best placement it was her recommendation to take them out of the right-of-way area so that would be something that we could look at just as was brought up before. We could look at placement once the house is, again you're looking at a box so that doesn't, we don't know what that plan's going to be because the consumer, the buyer is going to pick the house plan that they want and so when they're represented it gives people a false impression. We require a 60 by 60. These are substantially larger because what they're showing is the building envelope so that's the envelope they can build within to meet all the setback requirements so depending on how that sits on the lot, yeah there would be opportunities for trees and I think that's something we could look at as we, if this plan was to move forward that's something that we would come back with the Forester's recommendation on that. Where those would go. Hokkanen: Because some developments we have requirements of 2 trees in the front instead of 1. Aanenson: Exactly, yep. PIAI Chanhassen Planning Commission — May 17, 2016 Weick: In fairness though to that statement, there's 66 trees shown here. To get, we would need 45 more trees. I mean we're not talking about adding 10 trees. I mean this is, I don't even see regardless of how big or small the houses are on those pads, there isn't room for 45 more trees. There just isn't and so, okay. You could stuff them in Outlot 1 just like you stuffed them along Lake Lucy and I'm not sure that does what we, what the true intent of that canopy coverage is. That's my opinion. Hokkanen: I'm not a lover of flag lots. Not my favorite. I don't think it's, if there was a way around it I would like to see a way around it but it's not my favorite. Aller: Well let's talk about if the variance is not then granted because the flag lots don't meet the requirements what. Hokkanen: Just my opinion. Weick: Yeah but I'm not sure. Aller: But we need to discuss it because we have to decide on it. Weick: Right. I mean whether it's our preference or not for flag lots, I don't know. I mean I'm trying to think of the, to Commissioner Tietz's point the, if eliminating the flag lots helps place lots better, or more efficiently help with drainage or something to that effect you know I can see denying that portion of the variance but if it's simply you know our preference I don't think, I don't know that whether we should do that. Hokkanen: Because if you remove them, as he stated it's going to kill the project because they need that many lots. Aanenson: Can I just give you a little bit of our justification in looking at this? All those lots are significantly over the 15,000 and so we looked at kind of in the surrounding area. The Shadowmere subdivision just across on Lake Lucy has flag lots because they were permitted at that time. The main reason why we put the flag lot as a variance request is we wanted to make sure how the houses were oriented because we had people that were, just like we talked about, that lot to the left. If you put a house behind then it doesn't seem right so this way they're facing, really more facing the cul-de-sac so it's more traditional a look. It's just that the area is already larger kind of pinched up in that corner so that was our basis on whether that's right or wrong that's the stance we took on that. Allen: Any other comments at this point in time? Sir yes. Terry Forbord: Mr. Chairman, members of the Planning Commission, Terry Forbord. I want to just comment briefly on flag lots. I'm guessing as residents within this community many of you have lived here a long time or perhaps even in the west metro. Flag lots are all over the city of 26 Chanhassen Planning Commission — May 17, 2016 Minnetonka. All over the city of Wayzata and they're very common in the development patterns that exist and when you drive through most of those communities today you can't tell whether there's a flag lot or not. You see houses within tree canopies and streetscapes that are beautiful. And as was pointed out by staff until the last probably 10-15 years ago they were quite common in Chanhassen so I could take you on a tour all around the Lake Minnetonka area and there are thousands and thousands of them and there are many situations that create a better streetscape by doing it. The particular variance that Kate was referring to allows to be able to turn the house so the house is facing the streetscape which is very important purely from a marketing and merchandising and historic look into the future, or a future look so when you drive through the neighborhood you don't go why is that house kiddy whampus and turned sidewalks? So I encourage all cities, and I do consulting for cities. I'm working in Prior Lake right now helping them on this very issue so otherwise you do not end up with what I refer to as an articulated lotting pattern. Having an articulated lotting pattern is better than tunnel vision on a street and when those are built and the canopies and the landscaping develops you go through and they're beautiful. I'm sure everybody here has seen projects that I call, what are plagiarized all the time by large national developers where the streets are straight. Everything's a postage stamp. Everything is in a grid pattern. There's no articulation in any of the lots. What we're doing here is adding articulation in a very critical point not only from the topography but from the land form that is there and I, regardless of our site I would strongly encourage the City to continue to promote flag lots because they're an asset and they make for a better neighborhood community. Aller: Thank you. Any additional comments or discussion on the matter before us? We've got several things. With regard to infill I think we have to balance the infill and the difficulty of infill with the fact that a property owner has the right to try and attempt to get the value of his property and we as a city have to represent them as well as the neighbors that were there before and I think that balancing is what we're looking for. At least that's what I'm looking for and I'm seeing that so far in the ability to work with the City and the efforts that have been made in going through the process. The fact that our denial or granting would kill the project really doesn't have an impact on me. I'm looking at the project to see whether it's beneficial for the neighborhood and what do we get by granting the variance as opposed to looking for a reason to deny it and I think we gain the opportunity to have a better water rate and flow and stormwater system and as a result of that I'm easily swayed by the fact that I think it's a reasonable use of the property and I think that's what we should look at in making our determination so I'll be voting in favor. Weick: If I could ask for clarification on what we are, what we will be voting on? It feels like there's 3 things. So there's the rezoning. Aanenson: Correct. Hokkanen: Right. Weick: And we do have a, that's something that we're voting on. 27 Chanhassen Planning Commission — May 17, 2016 Aanenson: Correct. Weick: There's the variances. Aanenson: Correct. Weick: And then there's the actual preliminary plat approval for 12 lots. Aanenson: Correct. Weick: Okay. Aller: Did you want to discuss any of those 3 issues? Weick: I would. You know I guess, and I appreciate your comments. I would, this is very difficult. I'm very sensitive, like you are to the ability to, for homeowners to develop their land. That's absolutely, you know we should be supporting that. I don't have any issue with any of the variances actually. I don't have an issue with rezoning the property to single family residential. I do, as a matter of what I'm trying to do is figure out how the preliminary plat for the 12 lots, and I can't reconcile some of the significant issues that I see with the approval. So the approval of the preliminary plat and sorry for jumping around but you know it has to meet the subdivision regulations and the zoning ordinance so I read that and I tried to find, I tried to make sure that we meet the zoning ordinance and the subdivision regulations. To me there's 3 significant issues that this property is dealing with. One is the canopy or the tree coverage. It's significant to me. I don't think it can be remedied. I don't think that should necessarily stop the subdivision but to, we can't correct that to the point of getting to the city regulation I don't think. I think we're too far off there so I think that's a significant issue. I think the hard cover, and I know that's something that I guess deal with further, further through the process but based on flag lots and based on the way things are configured I'm significantly concerned about hard cover and I have not been, although attempts to reassure us that the mitigation of the drainage will be easy, I don't see that and I certainly don't see it in the report. It feels anything but easy so I think there's 3 issues that we're really dealing with and that the residents around are dealing with and so when you look at the conditions of the zoning ordinance, for instance condition on page, well it's 1 but, you know number 4, letter e. The proposed use can be accommodated with existing public services and will not over burden the city service capacity. I think we heard about sewage being an issue. We heard about drainage being an issue. In 5(c), the physical characteristics of the site including but not limited to topography, soil, vegetation, susceptibility to erosion siltation, susceptibility to flooding and stormwater drainage are suitable for the proposed development. I am not convinced of that. 5(d), the proposed subdivision makes adequate provision for water supply, storm basins, same kind of thing. I'm not convinced. And then G(1) is the same. It deals with drainage so, and then you know we can overcome that if you follow in 6. I don't believe the hardship is a mere inconvenience so I don't think that's met and I don't believe that 28 Chanhassen Planning Commission — May 17, 2016 the granting of a variance of the plat would, would not be substantially detrimental to the neighborhood basically paraphrasing what 6(d) says. So when I really try and take some of the emotion out of it and what people are trying to do with their land and what neighbors I think what I'm hearing are trying to accomplish as well, based on the facts that I see here, I don't think we meet the conditions for the preliminary plat and for that reason I would not vote for this. That's my, thank you. Alley: Okay, any other comments? Hokkanen: I want to thank Steve for kind of breaking that down because I similarly agree with almost everything you know without getting into details. Some of the conditions. If they could be met or they will be met that's different and we assume that they will because it'd be a condition but I'm a little torn on this as well. Weick: And we've dealt with these issues before but they've been more singular. Just as these start to add up to me, we have big issues on this property and I'm not sure we're ready with the current plan. I really appreciate that we've gone through multiple plans but just because we tried hard in my opinion doesn't mean we necessarily got there. Hokkanen: Close. Aller: Anything? Tietz: I just comment on the tree thing. I think that can be dealt with Steve. I think the 45 plus or minus trees after the fact, kind of like my comment earlier about banking trees and then the developer's responsible for bringing them as the development evolves I think could be very appropriately done and really add great value to the neighborhood if they're placed strategically and give homeowners an option of the type of tree and where they want them placed and then planted appropriately so I'm not as concerned about that. I think the big issue is just confirming the stormwater and the drainage. You know the number of lots does bother me but I understand the situation and obviously economics come into play. I'd like to see 9 foot retaining walls eliminated instead of hard 90 degree edges at the comer of the property that you know somehow kind of fits better. I can't change that so. Weick: One of the, you know in sitting through a lot of these we talk about after the fact like with hard cover or with trees. You know we look at the lot and we say well, the house is there and you can't put a tree within 10 feet of the house and the street is 15 feet from that and so the area to put a tree is very small and to that I would say that's our fault because there was a tree there and we decided to put a house there. A big house, right? A three quarter to a million dollar house or whatever it is and we built it in such a way, we approved it in such a way that the only area to put a tree was 6 square feet and we put a tree there and so I would argue to say that could it be done? Yes but we create a condition that makes it so difficult that I just question creating that condition. That's where I'm hung up and yeah. 29 Chanhassen Planning Commission — May 17, 2016 Aller: I look at this as an ongoing process because even though we're making decisions today it's to the preliminary plat. It's not to a final plat. It's not to the building permit. It's not to the contracts that are going to be entered into with the City so I look at the direction that we're going and as you know I'm a water guy. I want to know where it's going and how much is going there and I want to preserve it as well as the trees to the extent possible but I think when we're looking at the process here we're looking at conditions that are being placed upon them if we move this forward that we have to rely on the fact that we're going to follow through and get them done, and if they don't meet the requirements for hard cover then it's not going to be built. Weick: True. Hokkanen: Correct. I think this discussion is good to bring up these points. That they are important to us so moving forward the conditions can be met. Aller: And that it's not the final decision. Hokkanen: Correct. Aller: And that they, when I look at these things I also look at the extent to which the developer has been working with the staff and working with the community, not just because it goes through iterations of plans. I would think everybody would be happy if we could hit the mark on the first plan every time but the fact that they go through that process in making the sausage so to speak, you're going to come out with a better product and the fact that they go through it again and again and we have these discussions again and again and they listen to the community and to the impact that the community statements had on them is something that I take into consideration and I feel more comfortable with when I look at are our conditions going to be met. And with the number of trees versus houses I just, it's a difficult thing because how are we to determine how many trees a person should have on it's lot? Weick: Agreed. Aller: And where do you replace the house, the home that somebody wants to build on a lot versus the fact that they may not want trees. They want a house so we try to balance that the best we can. And the fact that we require it and that it goes through the process with the requirement we'll end up with I believe a better product in the end, and they might be smaller trees. They might not be huge oaks but they'll be overstory and they'll help again my thing with water is that overstory trees are the best thing that we can do. It's our initial defense to runoff. Weick: I would say if we believe this iteration provides the room down the road you know to make the changes necessary to meet some of the requirements then I can see where, I can see approving it. Chanhassen Planning Commission — May 17, 2016 Alter: And I think, but I think that that's what you need to decide. Weick: Right. Alter: How you're going to vote on it. Weick: I agree. Yeah. Alter: Personal viewpoint and whether or not, you know I'm not here to sell you. If you have any other questions for staff or anything let's get it out in the open and build a record. Aanenson: And I don't know if you saw it but part of our discussion in going back to the retaining walls is you know having a walkout versus a rambler on some of those lots would also change whether or not you need a retaining wall so there are other choices which we've pointed out in our staff report too. Generous:... stormwater runoff. Aanenson: Some of it, yes. Tietz: And those lots, what 7 and 8 or those two, they have to come around an 80 degree bend. Aanenson: Right, that's true. Alter: And that's also grading and elevation. Tietz: Right. Aanenson: They're changing the elevation for a lookout right. Tietz: Bring those up? Aanenson: Right. So we pointed that out in the staff report. Tietz: Yeah I noticed that. Alter: Sir. Terry Forbord: Commissioner Alter, members of the Planning Commission, Terry Forbord. Those are excellent questions that both Commissioner, is it Weick? Weick: Weick. 31 Chanhassen Planning Commission — May 17, 2016 Terry Forbord: Weick and Hokkanen brought up. Here's the saving grace. Number one, on the record I give you my utmost commitment to continue working with the staff and a best in class professional scenario that we have enjoyed over the last 5 months. But here's the saving grace for the City. All the issues that you brought up mean that you have to have an incredible staff to take care of each and every one of those and the good news is you do and you've witnessed it before. As Commissioner Aller just, you took the words out of my mouth moments ago. Advancing this forward as recommended by the staff, the city staff, to the City Council and working through to the final design and ultimately the final approval at the City Council where all the rubber ends at meeting the road including the developer's agreement and everything else, all those issues that were just brought up by you I am absolutely confident that your city staff and city attorney will take care of those issues and you need not worry about them. I'm glad that you bring them up because they're very critical and I give you my commitment that we will work with the staff to accomplish all of those criteria. Thank you. Aller: Thank you. Any other comments or? Hokkanen: No, ready for a motion. Aller: I'll entertain a motion as anyone deems fit. It could be any motion. It can be to table. It can be to deny. It can be to grant. Yusuf: Can I just ask one question? Where do we stand on this one? The remaining 4 conditions of approval that were. Aanenson: That's just their comments to our, those conditions are, they're refuting those or have some additional comments on it. We're sticking by our conditions in the staff report. Yusuf: Okay that's what I just didn't hear the staff's feedback on that. Aanenson: Correct. We're not in concurrence on those. Aller: We haven't heard a motion to change or modify those conditions. Yusuf: Just want to confirm since the motion that we'll be making will be the original conditions of approval. Aanenson: Right or the Chair says, we forward those as part of the record as this goes up to City Council. Yusuf: Okay. Aller: Were you about to make a motion? 32 Chanhassen Planning Commission — May 17, 2016 Yusuf. I can very well do it. Aller: Thank you. Yusuf.

Within the Highlands of Lake St. Joe neighborhood. The applicant is requesting a wetland alteration permit to construct a temporary dock on Lake St. Joe to utilize the lake for recreational purposes. This is the existing site and the location of the proposed dock overlooking Lake St. Joe. The applicant is requesting a wetland alteration permit in order construct a 3'/2wide wood dock extending approximately 95 feet into the wetland to an accessible lake depth of approximately 4 feet. This is the approximate dock location in relation to the wetland boundary. The dock would be mainly located where it is primarily cattails and in a semi -permanent or permanently flooded area. The wetland boundary is over here. There's a slight slope that goes, well probably a 3 to 1 slope actually that goes down from the property to the wetland boundary. The dock that is constructed or would be constructed would have to allow water to free flow underneath it. The approximate impact as a result of the dock is approximately 19 square feet. That's a result of the posts that are to be installed with the dock. This is, this meets the no loss criteria under the Minnesota Wetland Conservation Act. The De Minimis criteria. Within there are certain maximum impacts 9] CHANHASSEN PLANNING COMMISSION REGULAR MEETING SUMMARY MINUTES APRIL 19, 2016 Chairman Alter called the meeting to order at 7:00 p.m. MEMBERS PRESENT: Andrew Aller, Mark Undestad, John Tietz, Nancy Madsen, and Lisa Hokkanen MEMBERS ABSENT: Steve Weick, and Maryam Yusuf STAFF PRESENT: Kate Aanenson, Community Development Director; Bob Generous, Senior Planner; Alyson Fauske, Assistant City Engineer; and Terry Jeffery, Water Resources Coordinator OATHS OF OFFICE: Andrew Aller and Nancy Madsen recited the oaths of office.

The existing building on site is on one lot. There's a little extension to the southeast that the City currently owns. There's a purchase agreement in place to sell that to the property owner and Chanhassen Planning Commission —April 19, 2016 create one bigger lot. Previously on this site there was Prairie House restaurant and then after that the current commercial center, a 10,000 square foot multi tenant building was built in 1996 and now they're proposed to remove the existing building and put in a separate structure for Chick-fil-A. The property is zoned Highway and Business Services District (BH) which permits, it's really oriented to vehicular access type uses. It permits almost, the most commercial uses that we have in all our zoning districts. The property is guided for commercial uses. The zoning and land use are consistent with each other. Access to the property is via West 79t' Street on the north side. There's no direct access to either Great Plains Boulevard or Highway 5. On the west side of this property there's a joint access with the Chanhassen Inn and that will remain in place throughout this development. Again the request is for a site plan review approval for the construction of a one story restaurant building with a drive thru facility. It's about 4,775 square feet. The variance is for hard cover. They're requesting an increase from 65 percent which is permitted under the zoning ordinance to 77.5. We have proposed some revisions to the plan that reduce that but not a lot. It's still over 77 percent and we'll get into that later. And we'll address the variance first. Again they're requesting 77.5 percent hard cover. This property, the BH district provides for highway commercial development type uses and so it's really designed for vehicular uses. This is the most vehicular use if you had a drive thru restaurant on a commercial property. It has great visibility to the highway. Easy access. The joint access with the property on the west is part of the problem for hard cover maintenance. Generally we see perimeter landscaping where the properties can make up for their green space. In this case they can't. I took a 10 foot strip at 280 feet on the west side and that's why I came up that they lose at least 2,800 square feet of green space or pervious surfaces. They're trying to redevelop a site that currently exceeds the hard cover. It's at 81.9 percent now so that is over, the resulting percentage hard cover will be less than currently exists but they also have a slightly bigger property so the net result is it's about a wash between the proposed hard cover and what they have now. However we believe that it is a reasonable use of the property. They are trying, they're meeting all the city code requirements for green space. For parking lot landscaping. Perimeter landscaping and they have made some modifications that will, like I said reduce the amount from 77.5 to and I believe Joe may have the final number. They're still working on that. They're making some corrections. They'll go through that. Here's the site plan. It has some of the revisions. Originally the drive thru for the, had two drive lanes coming into it and so in this case you see that we had them reduce it down to one. They were able to pick up this comer for some landscaped area. It's potentially I don't know I have to ask Alyson if they can reduce the radius on this curve and add a little more green space. They were able to expand this patio area which was at one time it was limited to straight across here so it becomes a better functioning area for people to congregate and eat their food. Drive thru continues. We're also looking at trying to shorten up this sidewalk by at least a panel, maybe two if we can shift it to the west slightly and so they pick up some more green space. This is the area that they're purchasing from the City so that was just basically for the drive thru. It does represent a significant portion of their green space. We also are working with them to make sure all their landscape islands are at least 10 feet interior diameter. Interior dimensions of pervious surface so we have areas there. I was in some preliminary talks with Terry to see if it was possible if their proposed stormwater system doesn't work if we can use some of these landscape islands to provide a rain garden type 2 Chanhassen Planning Commission —April 19, 2016 area. That water from the parking lot that could flow directly into them and that's something we'll continue to look at. Again I just tried to highlight all the landscape areas in this. Again we are looking at expanding all the islands to meet the 10 feet interior dimension between, behind the curb. The perimeter on the east side is primary green space and then along the north property line. 'They're working there. As part of our review they are short a few trees and they have some trees that aren't really acclimated for this area so we recommend that they make some changes. There is an 8 inch oak that's right on this property line up here and it's just south of the Holiday and they will be preserving that in place so we will be receiving the revised landscape plans as they go forward showing that that will remain. Oh the stormwater system is underground here. We're seeing that a lot because there's not a lot of green area that they can. The concern is with the downstream system from this. That it is under sized and it won't accommodate additional stormwater runoff and so currently they have to meet the 1.1 inch of retention on site and so we're working with them to verify that their system will actually work. They need some additional information regarding the water table out there and then the calculations for the actual system. They will meet it. It's just how eventually it's done is may be modified as we go forward and get additional information. The building is, basically it's a two tone building. I sort of, we tried to design it to make it look like there's two components to it. Brick is the primary material and let's see I'll go to the overhead cam. The primary brick color is that red, the reddish brown brick on the left side. I can't even remember the name. Red velour is what they call it and then the other one is beige colored brick and that's primarily the entrance area and the eastern end of the building. They have dark bronze anodized window framing and also the coping at the top of the window and then also they have, we've had them incorporate metal canopies over the windows so all these darken areas represent canopies. These flat areas are also canopies but they're those flat projecting ones. They don't come down or up and so we see a lot of that in the new construction. These are actually functional canopies so they'll help in the summer months to reduce some of the heat into the building and that's one, it also provides additional architectural interest to those elevations. Okay each of these windows, these are actual metal canopies over the windows. The flat ones are over the entrance areas and the service doors so you'll see this is on the west end of the building. This is the west elevation. It's what you would see as you were coming down Highway 5 from the west. This is the south elevation. Here's north elevation. There's not, these are faux windows in here. This one is on the north end. It has a canopy. It's faux window also so this is a service area within the building and this is the east elevation as you're coming west on Highway 5 what you would see. Signage is composed, well it's permissible on 3 elevations. They're not using it on the north side of the building so they're using it on their main entrances which is on the west side. Right here above the main entry on the Highway 5 side. And then also on the Great Plains side of the building and that, we didn't do a review for compliance with city ordinance but that's a condition of approval that they have to meet the requirements under the BH district regulations for size. Lighting is proposed throughout the development. They have, they meet all the requirements in the parking lot. On the roof they do have one spotlight and I've been advised that that's to light the United States of America flag which is permitted under city ordinance so otherwise they have downcast lighting around the building. It's little sconces. As part of our review we want to make sure that they don't have, it's all downcast so it doesn't shine up and that again is a condition of approval. 3 Chanhassen Planning Commission — April 19, 2016 Here's the interior layout of the building. This is the north side up here. South, west and east of course and these are more service areas along on the south. Northeast comer of the building. There is a little play area in the southeast corner of the building. The patio area would be on, along the south side here. As a part of our review we requested that the applicant perform a traffic study of the area. Specifically at West 79t° Street and Great Plains Boulevard but then we also looked at it at Market Boulevard. Their engineer will talk about this more in the future. As always left turns are where we have problems with traffic circulation and so I'll let him get into that. It's currently an F. It will remain an F and eastbound West 79`s Street and Great Plains Boulevard unless we get different traffic patterns in the community. And again I'll let their engineer discuss that further. I think that's what that. Staff is recommending approval of the site plan with the variance for the hard cover subject to the conditions in the staff report and adoption of the Findings of Fact and Recommendation. With that I'd be happy to answer any questions. Aller: Anyone have any questions at this point in time of staff? Tietz: Yes. Aller: Commissioner Tietz. Tietz: Yeah Bob. Can you help clarify, there's code requires 60 stalls and they're putting in 72 stalls. What's, help me, help clarify what's driving that? Is that their analysis of traffic and what they think the facility's going to drive? Generous: Commissioner Tietz, yes. Basically it's their operating standard. They're looking for at least 70 stalls. With the modifications we're talking about I believe they may lose a couple so they'll be below that 73. Tietz: Because if they met code they'd have no problem meeting the coverage I don't think if you eliminated 12 stalls. Aanenson: That's correct. There was a lot of discussion on that when we fast met with them so we asked to see their analytics from other stores that they've built in the metro area what they used and that's what they determined. They gave us kind of their peak hours. What their biggest demand is. What they would need for that. Because it's tight parking in there right now, you have the Holiday and then ultimately we believe the other property's going to get redeveloped too. Tietz: The motel or the inn? Aanenson: Correct. Some day in the future. Tietz: Yeah. 4 Chanhassen Planning Commission —April 19, 2016 Aanenson: It's over 30 years in it's life cycle there so we did spend a lot of time with them on that. That was a big issue for them. I guess the perspective we took right now it's solid asphalt. There's no trees or anything in there. It was built to a different standard so because we were moving towards getting compliance and doing the underground stormwater treatment which isn't there right now, that was our position but you're right. If they dropped those stalls they could meet the requirement. Tietz: With a shared road Kate for entry is there any potential in the future that as that site to the west gets redeveloped that there is potentially a shared parking? Aanenson: Yes. I think that's what we could look at if it's offset demand just like we have down at the Villages on the Pond or we have actually in the Dinner Theater district. We actually have a nice matrix there looking at what peak demands are there so because we don't know what that use is going to be. We've had some interesting thoughts there that would drive up parking so yes. We always try to look at shared and that's something we might want to put in the standards too especially they're usually not open on Sundays so that might be something too that we might make a condition. That's a good point. Tietz: Thank you. Aller: Any further discussion at this time? Any questions? Okay, we'll have the applicant step forward if he'd like to make a presentation and please state your name for the record. Joe Vavrina: Sure my name is Joe Vavrina with HR Green. Project manager for the project. Aller: Welcome. Joe Vavrina: And I'm hereto represent Cluck-fil-A. Thank you for entertaining our proposal tonight. I figured I'd jump right into traffic. I know Bob had mentioned that there would be further discussion on that so I put together this quick overall exhibit to kind of highlight the area that we looked at. This area in here is the Chick-fil-A. Where the Chick-fil-A will be built and the two intersections that were looked at which was Great Plains and 79m and then Market and 79`s which is over here on this side. See if we can get that all in the picture maybe. So working with staff there was initial concern that on the intersection of Great Plains and 79th there's some back up potentially today with the eastbound left turns on 79th going northbound to Great Plains so we went out and did a traffic study on that intersection specifically to start. Looked at the peak hours. Both the midday as well as the pm peak during the week as well as Saturday during lunch hours. We determined, we went out and did counts between 11:00 and 1:00 during the week, 4:00 and 6:00 during the evening hours, and 11:00 and 2:00 on Saturdays. We determined the peaks were between 11:15 and 12:15 during the week. The pm peak was between 5:00 and 6:00 and then on Saturday it was between 11:30 and 12:30. So looking at those specific hours we developed the level of service analysis and queue determinations for the intersections in all the legs so the first item that we wanted to look at was the northbound left on Great Plains so that Chanhassen Planning Commission —April 19, 2016 would be this movement as you turn onto Great Plains to make the left into 79's. We wanted to make sure that there was no back up that would occur onto Highway 5. In the analysis that we looked at there was no level of service drop. It remained at, I believe it was an A which is the best level of service you can possibly get. Again there is no stop control on Great Plains in either the north or south bound directions so it's pretty much a free flow into 79'b. We then looked at all the other legs and really the leg that, you know as Bob had mentioned earlier that currently fails today is the eastbound left on 79' going northbound Great Plains. As the Chick-fil-A would develop it would concurrently remain to be an F so we looked at things that we could do to help mitigate that to help and improve the situation out there. We also looked at you know how does the traffic distribute coming into the Chick-fil-A and going out of the Chick-fil-A which is really going to be two different percentages. As traffic approaches we looked at an 85/15 split where 85 percent of the traffic comes from the east. From Highway 5 up through Great Plains and into the development and the other 15 would come from Market Boulevard down 791s and then into the development. From an existing perspective, again this is just during the peak, that percentage changes knowing that human nature is going to look at and see if there is a back up at this left turn lane at Great Plains, they're going to go to Market Boulevard because they know that hey there's alternate ways to get in and out of this area and they will take an alternate means to get out so the exiting distribution was a 65/35 where 65 would go out to Great Plains and then back to 5, or north and the other 35 would go to Market Boulevard. We looked at the level of service impacts at Market Boulevard as well and thanks to the City they provided, or staff provided us some counts they had recently done at Market Boulevard to help us understand how that intersection would operate today and in the future and really the only impact in movement was the westbound left onto Market. Currently today that operates at a level of service E and after development it would go to an F but it's marginally right at the E to F so right now it's a high E and when the Chick-fil-A goes to a very low F. It's like a 2 second difference as far as the time delay so in our opinion it's a negligible impact on Market. The improvements or recommendations that we came up with in the study to again help mitigate you know some of what's going on at the Great Plains intersection was to restripe this median here to extend it and create a longer left turn bay and storage. That would provide additional area for cars that are trying to make that left out. Room to stack so that they don't block the right, the right through combo. That is something that Chick-fil-A has committed to do if everyone deems to be acceptable. And then the other thing would be to possibly add some informational signage on site for those that aren't familiar with the area. That are visiting the site. Just passing through that if this access point appears to be congested that they could use the Market Boulevard access point as an alternate means to either go north or to get back to Highway 5. It's a challenging intersection being at Great Plains and 70. It's you know within 250 foot of Highway 5. You know a lot of the things that us as engineers use to help solve some of the traffic issues such as stop control, signals wouldn't work in this situation because it would create more of an issue to Highway 5 and back traffic up into Highway 5 so unfortunately we can't go with any of those solutions that we typically would look at and really are limited to the things that we can do out there. The restripe for the left turn lane makes sense. Provides additional storage. I think in the, with the proposed development we would fit all the vehicles in that peak hour which was 95 percentile that we looked at which was worst case scenario which doesn't happen every day. I 31 Chanhassen Planning Commission — April 19, 2016 was just out there tonight and there was nobody making a left turn out of there at 5:30 so I mean again it's the worst case scenario but in that event if we were to restripe this we could fit all those left turn movements in that and keep that right through open so that we don't back any traffic up into there to make it a little bit more safer so I guess with that I'll open up the questions on the traffic study itself. I know that's a big component of this proposal. Be happy to answer any other questions as it relates to the Chick-fil-A building. The site. Real quick I will add to the question on the number of parks. The 70 stalls that we have is, actually I think as Bob had mentioned we are, we have reduced it down and this plan here incorporates some of the changes that Bob was alluding to earlier with widening out the landscape islands to get that 10 foot back to back for here, here, here and actually that one's a little bit wider than 10 so we lost 2 spaces in the mix so right now we're at 71 stalls from where we originally proposed. Typically in this market you know we look to get at least a minimum of 70. That's what we've seen in this market that we need to operate. Anything less than that we start to bust at the seams if you will and we don't want to get in situations where people are parking in other areas that we don't have the ability to park in so that's the reasoning behind the increase of stalls that we are proposing. And then I guess a real quick blip on the building. This building here that we're proposing is a custom building so it, you will not find another one in Minnesota or in the Midwest quite honestly. The closest one that we've done this in is Omaha, Nebraska and it fits this site very well because it's a very odd shaped site and it's not very rectangular to fit some of our other prototypes so this will definitely be a very particular building for this site. Aanenson: Planning Commission just wanted you to know that the original application design we asked for changes so. And they complied with that so very appreciative of that. Aller: Great. Any questions at this point? I'm going to ask, the 70 is that in the game plan for you as a typical business plan model to also include your employees or expected employees? Joe Vavrina: That's correct. Aller: So we don't have to worry about employee parking. Joe Vavrina: Correct, that includes them. Aller: And did you take a look at the potential impact on the Holiday if the restriping is done for purposes of ingress and egress on their 2 driveways? Joe Vavrina: As far as access to them? Aller: Right. Joe Vavrina: Absolutely. Let me go back to that exhibit. Aller: What that potential impact might be. Chanhassen Planning Commission — April 19, 2016 Joe Vavrina: So as it's currently striped today with the outer stripe and the inner stripe and then the diagonal stripes inbetween, technically that's supposed to be, you're not supposed to cross that. Aller: Right. Joe Vavrina: It's aright-in/right-out. That's the way it's striped. Legally it's you know these entrances are technically right-in/right-out. Obviously everybody uses that. They enter that. It's not enforced. If we were to extend the left turn storage bay my thought would be if no one's in the storage bay people are still going to continue to make that movement. If, and if you get into a situation where this is full and somebody needed to get into here you know they could always go past and make a U turn and come in which again and this is not a preferred option but they could do that. That pavement out there is wide enough to make that. It's almost 36 feet wide so they could make a U turn to get back to the gas station if they had to and again we're talking worst case scenario. Peak hour which is for a small period of time. Aller: And then water disposal, what's the potential if you know at this point for that to not only meet but to be able to avoid having downstream impact based on the stormwater drainage? Joe Vavrina: Sure. So right now what we're looking at is the underground system as Bob had mentioned and really you know the thing that we need to clarify and get some more information from our geotechnical engineer is you know where the ceiling high ground water actually ends up and is that, the area that we're going to put the cell is that inundated with ground water. If it is then our solution that we currently have is going to be challenged because it's kind of hard to store the water if there's already water in there from ground water so we may have to look at alternate solutions but if we can show that the ground water is lower than that you know the solution would be is that we're going to store the 1.1 inches. Infiltrate that into the ground and then everything else will flow beyond. You know the intent is that our discharge that we, that leaves the site will be at or less than what it is today so we will improve the situation. We're definitely not going to make it worst. We will do some additional modeling to verify some of the additional work that we're doing out here in the right-of-way. Some of the drainage swales that we're putting in that you know there's not a negative impact on that storm sewer that goes under Highway 5. Aller: Great. And then trash bins or trash, refuse what are we using? Joe Vavrina: Excuse me. Aller: Where's the trash bins? Joe Vavrina: Right here at the top of the site. Chanhassen Planning Commission — April 19, 2016 Aller: So easy access in and out? Joe Vavrina: Yes, for the garbage truck. Aller: And it's got good coverage so it's protected. Joe Vavrina: Yes. Aanenson: It will be similar to what like Taco Bell has. Their's are up against West 78th Street. Aller: Any additional questions? Thank you sir. Joe Vavrina: Thank you. Aller: Okay. I haven't led off with my usual spiel so I'll kind of go through that real quick. We are a representative body recommending to the City Council for approval on these items and this item if approved would go to the City Council for final action and after we have the presentations as we just have had from staff and the applicant we open up the matter for public input so I will do that at this time. If anyone wishing to speak for or against the item before us tonight wishes to come forward they can do so. Please come forward. State your name and address for the record. Seeing no one come forward I will close the public hearing and open it up for commissioner comment. Comment? Thanks to staff for putting together such a great package. It's very complete. For those of you at home that don't have it in front of you, you can have access to all our Minutes and the packages that come before us on our city website so feel free to take a look at the packages as they progress through planning and City Council. I don't have any additional questions or comments. I think it looks like they've done a good job in working with planning and coming up with something that appears to work for the site very well. I look forward to seeing a building that Chanhassen that no one else in Minnesota or the country might have so with that. Tietz: The new prototype. Good package. Aller: Any additional? Tietz: Well done. Aller: I'll entertain a motion. Hokkanen: I'll make a motion the Chanhassen Planning Commission recommends City Council approve the site plan with variance for hard surface coverage subject to the conditions of approval and adopts the Findings of Fact and Recommendation. Aller: I have a motion. Do I have a second? Chanhassen Planning Commission — April 19, 2016 Madsen: Second. Aller: Having a motion from Commissioner Hokkanen and a second from Commissioner Madsen, any further discussion? Hokkanen moved, Madsen seconded that the Chanhassen Planning Commission recommends City Council approve the site plan for a 4,775 square foot, one story building with a drive-thru and a variance for hard surface coverage, plans prepared by HR Green, Inc., dated 02/23/16 and subject to the following conditions and adopts the Findings of Fact and Recommendation: Building: 1.

APPROVAL OF MINUTES: Commissioner Madsen noted the verbatim and summary Minutes of the Planning Commission dated March 15, 2016 as presented. COMMISSION PRESENTATIONS. Aller: Any announcements by the commissioners? Aanenson: Ms. Hokkanen do you have an announcement? Hokkanen: I have to tender my resignation as of June I'. We will be moving out of Chanhassen. Very sad to leave after 21 years. It's a step for my family. IV) Chanhassen Planning Commission —April 19, 2016 Aller: We all appreciate the fact that in those 21 years you've done a lot for the city and it's residents both in your professional capacity as a realtor but your personal input and being here in the community as an individual and then certainly last but not least your service here on the Planning Commission. Using your expertise to a great advantage for the betterment of all of Chanhassen so we really thank you. Hokkanen: It's been my privilege. Aller: And wish you the best of luck and we'll see you on Highway 5. Hokkanen: I still work in Chanhassen. Aanenson: That's right. We'll get you for another meeting or two yet but yep. ADIVIINISTRATIVE PRESENTATIONS. Aller: And were we going to cover the open house for Highway 5 at all in our update? Aanenson: Yes. Just talk about a couple other things. Yes. I mean that's, Highway 5 open house. 41 open house? What? Aller: The Highway 5 and Chanhassen, the right turn acceleration lane, public open house next Thursday, April 28th from 4:00 to 6:00 p.m. here at the Chanhassen council chambers so if you want to get details of the project and ask questions of the project staff that will be right here on April 28 h from 4:00 to 6:00 and they'll talk about adding the acceleration between both junctions of Highway 101. Replacing the traffic signal at Great Plains Boulevard with the flashing yellow arrows and replacing the pedi trail between Highway 100, Dakota Avenue and Great Plains Boulevard. Aanenson: Yeah I don't know if Alyson wants to add anything. Fauske: Commissioner Aller you provided some great information. This project is headed by MnDOT and so staff requested that MnDOT hold an open house for those that would be impacted. There will be a closure of Market Boulevard but they've been limited as to the time that they can have Market Boulevard closed to accommodate those movements. And as you stated the improvements are for some acceleration lanes along Highway 5 that they like to get in before the Ryder Cup comes into, goes into Chaska. Aller: So hopefully a good safety improvement for that intersection. Fauske: Correct. 13 Chanhassen Planning Commission —April 19, 2016 Aller: Any additional City Council action updates? Aanenson: I have a couple things. On March 20 the City Council did discuss the stable permit for a miniature pony... Sorry, I said pony. It's a miniature horse. Aller: Mini horse. Aanenson: They're different things. Then some businesses... Jersey Mike's is going next to Noodles so if you look at what the Chick-fil-A looks like, they mimic some of the same features that are on that building for Noodles and now Jersey Mike's... and bakery is going in on West 79'b Street. ...we do have a subdivisions coming in on Lake Lucy Road... Then on May 17'h there's some things going out there but none of those came in but I believe you will have a wetland alteration permit on that meeting. Terry Jeffery will be handling and then some of those other things ... we're not sure where Wilson Nursery stands but there's also a subdivision... I did want to let you know that the lifestyle center, it's coming in. They've given us a date and that will be on July 19'b. That will be concept. Again on that a concept is not legally binding but it is our job to kind of give them direction on where we see that going. The council will also be discussing this on their work session before... before the public hearing. After that there's a lot of environmental stuff that needs to be updated with the AUAR... give them some marching orders ... for probably 4 months or so while they work through those issues. I don't know if you know or not but the City's working on that west water treatment so there's meetings going on about that. I know Alyson's done some background work on that. Bob started working on the site plan approval... so they've got that scheduled to come before you to look at that and that's right off of Galpin. Galpin Boulevard and south of Sugarbush Park ... Lake Harrison. North of that. Then also I just want to remind you that tomorrow night we're having a visioning I know some of you will not be there. Others that are not here tonight will be there. That's with all the commissions and there will be, after that meeting there will be some take away so we'll be sure... The intent was to go through the work plan that we put together to talk about the Comprehensive Plan which will be our big push this year and next year and again because you hold all the public hearings, you're kind of the most, the vested in some of that process too so I'm looking for an exciting and I think it's good to get all of our commissions together too. To do some bonding there so I've put a lot on your plate these 2 weeks. Appreciate everybody going along and then we do have in August we're going to have the joint tour with the Environmental Commission and Park Commission too and I believe we've set that for, I want to say the 10'b and that's the normal commission. I'll get this on the schedule. I realized now I didn't have that on there so you can bookmark that so we'll think about what topics we want to look at. It might relate to the comp plan or not. We'll see what else. It might be the lifestyle center. Talk about some of the amenities down there. Things we're trying to preserve but Chairman that is all I had for kind of the administrative. Oh I'm sorry, I did pass out one other thing too and that was if anybody's interested in taking one of these classes let me know. I'll sign you up for that. Aller: Great, thank you. 14 Chanhassen Planning Commission —April 19, 2016 Aanenson: Yep. Aller: Okay I think we've run through the agenda for this evening. Aanenson: Except for Terry's open discussion here. Aller: Open discussion so we will go into a work session after we adjourn and at this point in time I'll entertain a motion to adjourn. Undestad moved, Madsen seconded to adjourn the meeting. All voted in favor and the motion carried unanimously with a vote of 5 to 0.

The final plat for Anthem on the Park subject to the conditions of the staff report; 2. The development contract for Anthem on the Park; and 3. The plans and specifications for Anthem on the Park Approval requires a simple majority vote of City Council. PROPOSAL SUMMARY The applicants, Yosemite Holding, LLC, Almond & Carolyn Krueger and Craig & Deanna Claybaugh, are requesting final plat approval to create 12 lots, one outot, and right-of-way for public streets for the property located at the northwest comer of Lake Lucy Road and Yosemite Avenue. BACKGROUND On June 13, 2016, the Chanhassen City Council approved: Public Works 7901 Park Place Rezoning of the property from Rural Residential, RR, to Single -Family Phone:952.227.1300 Residential, RSF, and Fax:952.227.1310 Senior Center Preliminary plat approval for 12 lots, one outlot and public right-of-way with Phone: 952.227.1125 variances for the use of flag lots, cul-de-sac bubble size and a local street Fax:952.227.1110 centerline offset of less than 300 feet and a building setback variance from the cul-de-sac bubble for lot 11. Website www.ci.chanhassen.mn.us Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow Todd Gerhardt Anthem on the Park Final Plat — Planning Case 2016-09 August 22, 2016 Page 2 SUBDIVISION REVIEW The applicant is creating 12 lots and one outlot from 8.96 acres. The plat will dedicate the right-of- way for portions of Lake Lucy Road, Yosemite Avenue, and Anthem Place. Outlot A contains wetlands and storm water ponds and will be dedicated to the city and preserved as permanent open space. RIGHT-OF-WAY AND EASEMENTS The survey included all easements and right of way shown on the title search of the property dated November 20, 2015 from Stewart Title Guarantee Company. The applicant shall have their survey confirm this with a recent title survey before recording final plat. The applicant proposes a 60-foot right-of-way over Anthem Place and 60-foot right-of-way radius over the cul-de-sac bubble. The plat maintains the existing, 66-foot right-of-way easements for Lake Lucy Road and Yosemite Avenue. The City Council approved a variance on the right-of-way for the cul-de-sac bubble to be decreased to 50 feet at Lot 11, Block 1. Staff recommends the applicant revise the plans to incorporate this variance and increase the size of the stormwater basin on the east side of Lot 12. The retaining wall on Lots 5 and 6 proposed within the drainage and utility easement requires an encroachment agreement. An entry monument is shown on Lot 1. This shall require a paper easement between Lot 1 and the HOA that shall be recorded prior to construction of the entry monument. The site plan shows an entry monument on Lot 1. This shall require an encroachment agreement between Lot 1 and the development's HOA to be recorded prior to construction of the entry monument. Per § 18-78, staff and the applicant examined providing future access for adjacent properties to the west, 1650 and 1670 Lake Lucy Road. However, it is uncertain how these properties would develop in the future and what type of legal encumbrance Lot 5 would require. Staff recommends 1650 and 1670 have access off of Lake Lucy Road when they develop in the future. GRADING Drainage Under existing conditions, the site is divided into two major drainage area. A line that extends approximately from the southeast property corner to 150 feet south of the northwest corner divides the drainage areas. Everything north and east of that divide drains to one of two wetlands and is ultimately directed to the east through a new culvert to be installed under Yosemite. Todd Gerhardt Anthem on the Park Final Plat — Planning Case 2016-09 August 22, 2016 Page 3 Southern Drainage Area Everything south and west of this divide drains to the south towards Lake Lucy. The drainage leaves the site via a culvert that goes under Lake Lucy Road and discharges onto private property to the south. The drainage then either goes through a twelve inch (12") corrugated metal pipe culvert under the private driveway which leads to the island on Lake Lucy or portion of the drainage travels past the culvert and follows an incised ditch along the drive to a wetland located on private property. A second twelve -inch (12") CMP culvert goes under the same drive at this location and appears to equilibrate the wetland with another wetland on the other side of the drive. It appears the drive at this location is the low spot for the area and is prone to overtopping. Regardless of which path the drainage takes relative to the driveway; it all ends up in a third wetland with no constructed outlet although it appears that it does drain overland to Lake Lucy if it bounces approximately five (5) feet. None of this conveyance is under city easement nor does it appear designed to city standards. Staff has received email and voice correspondence from owners of four of the properties to the south that already receive runoff from the subject property. They all expressed great concern over directing Figure 1. Southern drainage route to Lake Lucy. additional runoff to the south. Staff agrees that the lack of easement and infrastructure makes it untenable to send any additional runoff to the south. These property owners should not bear responsibility for the stormwater management of the subject property. The development of this site must not direct any additional volume of runoff to the south. Further, rates must not be increased over existing rates for any scenario. The applicant must demonstrate to staffs satisfaction that this condition is met. The current plan iteration reduces the drainage area to the south by 1.07 acres. It is the consulting engineer's contention that the existing site conditions warrant a composite curve number (CN) of 79 and that even though the site CN increases to 85under developed conditions the total volume of decreases under each design event as shown in table 1 below. Todd Gerhardt Anthem on the Park Final Plat — Planning Case 2016-09 August 22, 2016 Page 4 Table 1. Runoff Volume by Storm Event Pre- and Past -Development. EXISTING RUNOFF CN = 79 PROPOSED RUNOFF 2 YEAR 0.337 AF 0.324 AF 10 YEAR 0.674 AF 0.592 AF 100 YEAR 1.530 AF 1.237 AF There have been numerous studies showing that, after mass grading, a site will be more compacted than under current conditions. Mass graded sites intentionally compact soils to increase strength for paved areas and building pads. This increase in compaction leads to an increase in bulk density and a decrease in soil porosity. This translates into an increase in the volume of water running off the site. The submittal assumed that bulk densities would remain the same after completion of mass grading as they are under the current conditions. Without a soil management plan indicating how bulk density will be reduced after completion of grading, staff feels this assumption to be erroneous and the composite curve number post development will be significantly higher than under existing conditions. The applicant must provide a soil management plan indicating site -specific remediation of soil compaction and practices to improve tilth, soil organic content, and infiltration rates. The applicant must demonstrate that bulk densities are no greater than existing conditions by providing penetrometer data for current conditions and post development and comparing them to some reference such as the NRCS Soil Quality Institute's 1999 findings. If the bulk densities are found to be elevated post -development the developer would be responsible for correcting the soils. Cul-de-sac Drainage A low spot exists at the 3 o'clock position on the proposed cul-de-sac. It is staffs preference that this low spot be removed and that positive drainage take place toward the east. The applicant's engineer feels this is not practicable and instead proposed to install a sump manhole at this location to discharge water to the wetland buffer. Drainage of Lots 6-10 In an effort to force look outs onto these lots, several issues are created, including drainage issues. Both lot 7 and lot 8 have drainage shed directly at the structures. This is an unacceptable condition. Because of the swales necessary for conveying water out of the backyards, nearly the entire backyard of lots 6 and 9 will need to be under a drainage and utility easement. This will preclude almost any landscaping as that would have a strong likelihood of creating impoundment conditions on the upstream properties. If these lots were made into full basement units it is possible that less water would be directed south, that greater treatment could be achieved and the likely drainage issues could be avoided. Todd Gerhardt Anthem on the Park Final Plat — Planning Case 2016-09 August 22, 2016 Page 5 Outlot Drainage The proposed biolfiltration feature has a 100-year high water elevation of 1008.11. It appears that this will bounce into lot 12. Given the nature of this facility, frozen conditions and sediment deposition will decrease the available pore space and can result in increased flood elevations. No emergency overflow has been provided and the plan view does not show the vertical or horizontal placement of the underdrain. The applicant will need to create an overflow between the northern wetland and the southeastern wetland. This must be stabilized and a vegetation restoration plan must be developed. The plans shall indicate that no wetland impacts, including but not limited to the placement of soils and the operation of equipment within the wetland can occur. In addition to the above discussion the following observations were also made pertaining to the grading and drainage plan: Lots 3, 4 and 5 on the southern half of the property show little level back yard area. This may be problematic for future owners of these lots as there is often an expectation to have a level backyard area for recreational use. The grading plan shall be revised to show a spot elevation at the centerline of the driveway where it meets Anthem Place. Draintile is required for all lots where stormwater runoff will flow from the back to the front of the property. Draintile shall be shown on the plans for Lots 7 and 8. All draintile that crosses lot lines shall be owned and maintained by the HOA. Velocity dissipation shall be added to the plans for the draintile outlet on Lot 10. The erosion control plan shall be revised prior to construction, to require steel posts for all silt fence. Based on the building pads shown, the hardcover area generating stormwater runoff on Lots 1-4 and 6-10 exceed the 25% maximum without taking the driveways into account. Many greatly exceed 25% and go as high as 37% hardcover. The applicant shall include a chart with the maximum hardcover allowed on each lot. The lots shall be graded to drain away from proposed building locations. Spot elevations shall be shown on the plans to verify that water will drain away from buildings at the following locations: Lot 6 backyard, Lot 7 backyard, the east side of Lot 1, the highpoint of the side yard of Lot 10. The southern basin shows an Emergency Overflow (EOF) onto Lake Lucy Road, a collector roadway. Todd Gerhardt Anthem on the Park Final Plat — Planning Case 2016-09 August 22, 2016 Page 6 To minimize additional stormwater runoff created by long driveways required for the "flag" or "neck" lot variance, the applicant's plans show proposed 10-foot driveways for the length of the "neck". The applicant shall identify the discharge point of the culvert shown on the existing topography near the existing driveway of 1600 Lake Lucy Road. If it is a driveway culvert, the applicant shall have it removed or bulkhead and abandoned. Erosion Prevention and Sediment Control The proposed development will exceed one (1) acre of disturbance and will, therefore, be subject to the General Permit Authorization to Discharge Stormwater Associated with Construction Activity Under the National Pollution Discharge Elimination/State Disposal System (NPDES Construction Permit). The applicant has prepared a Surface Water Pollution Prevention Plan (SWPPP) and submitted it to the city for approval prior to final plat review and approval. The SWPPP must be updated to include additional required information after the contractor and subcontractors are selected. No earth disturbing activities may occur until the SWPPP is updated with all required information. This SWPPP shall be a standalone document consistent with the NPDES Construction Permit and shall contain all required elements as listed in Parts III and IV of the permit. The city has a checklist which they will make available to the consulting engineer. SITE CONSTRAINTS Wetland Protection The City of Chanhassen Wetland Inventory and the Minnehaha Creek Watershed Wetland Inventory both indicate the presence of two wetlands on the subject property. Sambatek reviewed and delineated the site in October of 2015. Staff reviewed and approved the delineation that same fall. The notice of decision was mailed on November 17, 2015. The applicant provided MNRAM and determined the northerly wetland to be manage classification 2 and the easterly wetland to be manage classification I requiring a 20 foot and 25-foot buffer respectively. Both wetlands require a 30 setback from the buffer for the principal structure. The plans show the appropriate buffers and setback. It is the City's practice to have wetlands and buffers placed into outlots to implement the no net loss goal. The city requires that all runoff is treated prior to discharge into a wetland. Treatment practices are being proposed for much of the drainage being directed to the wetlands. It is proposed that lots 8, 9 and 10 as well as the backs of lots 11 and 12 be treated via the wetland buffer. In those cases, where no other treatment opportunities are available filter strips may be utilized. The upland area between the two wetlands will need to be graded to allow for the bounce from the northern wetland to spill over into the eastern wetland. Work will also be required adjacent to the wetland area to install the outlet pipe under Yosemite. The SWPPP must address the potential for wetland impact and how impacts will be avoided. No materials or staging can occur Todd Gerhardt Anthem on the Park Final Plat — Planning Case 2016-09 August 22, 2016 Page 7 within the wetland area. Any disturbed area within the buffers must be revegetated with native vegetation and a vegetation establishment plan must be provided. Bluff Protection There are no bluffs on the property. Shoreland Management The property lies approximately 225 feet beyond the shoreland overlay district for Lake Lucy. As such it will not be subject to shoreland requirements for land development. F000dplain Overlay This property does not lie with a floodplain. RETAINING WALLS The applicant has proposed one new retaining wall as part of this subdivision. The retaining wall at the comer of Lots 5 and 6 is approximately 125 feet long and 6 feet tall. The sideyard of Lot 5 and the backyard of Lot 6 are below this wall. As this wall crosses lot lines, it shall be owned and maintained by a Homeowners Association (HOA). STREETS The applicant proposes construction of a public street, Anthem Place. Anthem Place is proposed as an approximately 1580-foot long cul-de-sac, which will be 31 feet wide and constructed using the Chanhassen Standard Detail typical section. The applicant shall include the horizontal alignment tabulation for Anthem Place in the plans prior to construction. Access to the subdivision from Anthem Place is located south of the southeastern wetland. This location was chosen after examining three locations: off of Lake Lucy Road, Yosemite Avenue north of the wetland, and Yosemite Avenue south of the wetland. The Lake Lucy Road intersection alternative was eliminated because of sight -distance concerns around the curve on Lake Lucy Road and the desire for access control on Lake Lucy Road, a Major Collector roadway. The Yosemite Avenue access north of the wetland was eliminated due to environmental concerns from running a roadway between the two wetlands across their EOF point and future maintenance concerns due to a long road extension that is surround by wetland instead of servicing properties. The proposed plan includes a variance to the requirement of 300-foot spacing between local roads per §18-57 which was approved by the City Council. The access location on Yosemite, south of the wetland reviewed using engineering discretion and the guidelines set forth in the 2030 Comprehensive, the proposed intersection offset seems reasonable as the proposed 12 lot subdivision would generate less traffic than a multiple commercial driveway. The applicant's engineer completed a queuing analysis to confirm that traffic queuing to make a left turn into the Todd Gerhardt Anthem on the Park Final Plat — Planning Case 2016-09 August 22, 2016 Page 8 proposed development would not affect the function of the Lake Lucy Road & Yosemite Avenue intersection. The developer shall show construction limits for utility work on Yosemite Ave and submit a staging and restoration plan prior to construction of the work on Yosemite Avenue. The profile alignment for Anthem Place shall be revised, prior to the start of construction, at Station 16+00, so that the vertical curve is a minimum of 144 feet in length, or otherwise adjusted to meet the City Code requirements § 18-27(h). DRIVEWAYS AND TRAILS Driveways shall be designed to meet all standards in City Code §20-1122. To minimize additional stormwater runoff created by long driveways required for the "flag" or "neck" lot variance, the applicant's plan proposes 10-foot driveways for the length of the "neck". The sidewalk does not continue north of Anthem Place, therefore the pedestrian ramp at the intersection of Anthem Place and Yosemite Avenue is not required. The pedestrian ramp on the northwest comer of the intersection of Lake Lucy Road and Yosemite Avenue shall be replaced per City of Chanhassen Standard Detail Plates. SANITARY SEWER AND WATERMAIN Sanitary Sewer The applicant proposes an 8" PVC sanitary sewer main to be owned and maintained by the City, due to the elevation of the adjacent sanitary sewer system on the east side of Yosemite Avenue, sanitary sewer for this subdivision does not meet the minimum depth required without insulation. The sanitary sewer pipe shall be insulated wherever it is less than 6 feet deep. The sanitary services may also need insulation. The proposed shallow elevation of the sanitary sewer also necessitates Lot 1-4, 11, 12 to use a private, in -home grinder system to pump waste to the public sanitary main which is a gravity flow system. The portion of the grinder pump services that lies within the right-of-way shall be gravity -flowing. Per § 18-78, the applicant proposes to install sanitary sewer main to the western property boundary to provide future extension to the adjacent properties: 1650 and 1670 Lake Lucy Road. It is unlikely they would be able to connect a gravity system to the sanitary main extension and are expected to require private grinder pump systems. The retaining wall would need to be removed at the time of connection at the connecting party's expense. MH #4 shall be moved north to reduce the length of services for Lots 8, 9 and 10. Todd Gerhardt Anthem on the Park Final Plat — Planning Case 2016-09 August 22, 2016 Page 9 Water Main The applicant proposes an 8" C900 water main system. Hydrants are proposed at the end of the cul-de-sac, the mid -length of Anthem Place, and at the intersection of Anthem Place and Yosemite Avenue. The plan shall be revised to move the hydrant at the intersection north of Anthem Place to stub watermain for a future connection to the north. STORM WATER MANAGEMENT Article VII, Chapter 19 of City Code describes the required storm water management development standards. Section 19-141 states that "these development standards shall be reflected in plans prepared by developers and/or project proposers in the design and layout of site plans, subdivisions and water management features." Storm Water Utility Connection Charges . These fees can be credited up to 50% if the design has a reasonable expectation of achieving abstraction of the first 1.1 inches of runoff from all proposed hardcover on the site. The wetland and buffer and upland area put into the outlot will be removed from the assessed property. This fee will be applied to the new lot of record being created. It is calculated as shown in the table below. ASSESSMENTS Water and sewer partial hook-ups are due at the time of final plat. The partial hook-up fees will be assessed at the rate in effect at that time. The remaining partial hook-ups fees are due with the building permit.

Phased Development. If the plat is a phase of a multiphased preliminary plat, the City may refuse to approve final plats of subsequent phases if the Developer has breached this Contract and the breach has not been remedied. Development of subsequent phases may not proceed until Development Contracts for such phases are approved by the City. Park charges and area charges for sewer and water referred to in this Contract are not being imposed on outlets, if any, in the plat that are designated in an approved preliminary plat for future subdivision into lots and blocks. Such charges will be calculated and imposed when the outlots are final platted into lots and blocks. 3. Preliminary Plat Status. If the plat is a phase of a multi -phased preliminary plat, the preliminary plat approval for all phases not final platted shall lapse and be void unless final platted into lots and blocks, not outlots, within two (2) years after preliminary plat approval. 4. Changes in Official Controls. For two (2) years from the date of this Contract, no amendments to the City s Comprehensive Plan, except an amendment placing the plat in the current urban service area, or official controls shall apply to or affect the use, development density, lot size, lot layout or dedications of the approved plat unless required by state or federal law or agreed to in writing by the City and the Developer. Thereafter, notwithstanding anything in this Contract to the contrary, to the full extent permitted by state law the City may require compliance with any amendments to the City's Comprehensive Plan, official controls, platting or dedication requirements enacted after the date of this Contract. 5. Improvements. The improvements specified in the Special Provisions of this Contract shall be installed in accordance with City standards, ordinances, and plans and specifications which have been prepared and signed by a competent registered professional engineer furnished to the City and approved by the City Engineer. The Developer shall obtain all necessary permits from the Metropolitan Council Environmental Services and other pertinent agencies before proceeding with construction. The City will, at the Developer's expense, have one or more Wei construction inspectors and a soil engineer inspect the work on a full or part-time basis. The Developer shall also provide a qualified inspector to perform site inspections on a daily basis. Inspector qualifications shall be submitted in writing to the City Engineer. The Developer shall instruct its project engineer/inspector to respond to questions from the City Inspector(s) and to make periodic site visits to satisfy that the construction is being performed to an acceptable level of quality in accordance with the engineer's design.

The Developer's surveyor shall submit a written notice to the City certifying that the monuments have been installed. 7. License. The Developer hereby grants the City, its agents, employees, officers and contractors a license to enter the plat to perform all work and inspections deemed appropriate by the City in conjunction with plat development. 8.

All areas disturbed by the excavation and backfilling operations shall be reseeded forthwith after the completion of the work in that area. Except as otherwise provided in the erosion and sediment control plan, seed shall be certified seed to provide a temporary ground cover as rapidly as possible. All seeded areas shall be fertilized, mulched, and disc anchored as necessary for seed retention. The parties recognize that time is of the essence in controlling erosion and sediment transport.

No development will be allowed and no building permits will be issued unless the plat is in full compliance with the erosion and sediment control requirements. Erosion and sediment control needs to be maintained until vegetative cover has been restored, even if construction has been completed and accepted. After the site has been stabilized to where, in the opinion of the City, there is no longer a need for erosion and sediment control, the City will authorize the removal of the erosion and sediment control, i.e. hay bales and silt fence.

Construction hours, including pick-up and deliveries of material and equipment and the operation of any internal combustion engine, may only occur from 7:00 am. to 6:00 p.m. on weekdays, from 9:00 am. to 5:00 p.m. on Saturdays with no such activity allowed on Sundays or on legal holidays. Contractors must require their subcontractors, agents and supplies to comply with these requirements and the Contractor is responsible for their failure to do so. Under emergency conditions, this limitation may be waived by the written consent of the City Engineer. If construction occurs outside of the permitted construction hours, the Contractor shall pay the following administrative penalties: First violation $ 500.00 Second violation $ 1,000.00 Third & subsequent violations All site development and construction must cease for seven (7) calendar days M. Noise Amplification. The use of outdoor loudspeakers, bullhoms, intercoms, and similar devices is prohibited in conjunction with the construction of homes, buildings, and the improvements required under this contract. The administrative penalty for violation of construction hours shall also apply to violation of the provisions in this paragraph. N. Access. All access to the plat prior to the City accepting the roadway improvements shall be the responsibility of the Developer regardless if the City has issued building permits or occupancy permits for lots within the plat. O. Street Maintenance. The Developer shall be responsible for all street maintenance until streets within the plat are accepted by the City. Warning signs shall be placed by the Developer when hazards develop in streets to prevent the public from traveling on same and directing attention to detours. If streets become impassable, the City may order that such streets shall be barricaded and closed. The Developer shall maintain a smooth roadway surface and provide proper surface drainage. The Developer may request, in writing, that the City plow snow on the streets prior to final acceptance of the streets. The City shall have complete discretion to approve or reject the request. The City shall not be responsible for reshaping or damage to the street base or utilities because of snow plowing operations. The provision of City snow plowing service does not constitute final acceptance of the streets by the City. P. Storm Sewer Maintenance. The Developer shall be responsible for cleaning and maintenance of the storm sewer system (including ponds, pipes, catch basins, culverts and swales) within the plat and the adjacent off -site storm sewer system that receives storm water from the plat. The Developer shall follow all instructions it receives from the City concerning the cleaning and maintenance of the storm sewer system. The Developer's obligations under this paragraph shall end two (2) years after the public street and storm drainage improvements in the plat have been accepted by the City. Twenty percent (20%) of the storm sewer costs, shown under section 6 of the special provisions of this contract, will be held by the City for the duration of the 2-year maintenance period. Q. Soil Treatment Systems. If soil treatment systems are required, the Developer shall clearly identify in the field and protect from alteration, unless suitable altemative sites are first GC-8 provided, the two soil treatment sites identified during the platting process for each lot. This shall be done prior to the issuance of a Grading Permit. Any violation/disturbance of these sites shall render them as unacceptable and replacement sites will need to be located for each violated site in order to obtain a building pemrit. R. Variances. By approving the plat, the Developer represents that all lots in the plat are buildable without the need for variances from the City's ordinances. S. Compliance with Laws. Ordinances. and Re ations. In the development of the plat the Developer shall comply with all laws, ordinances, and regulations of the following authorities: 1. City of Chanhassen; 2. State of Minnesota, its agencies, departments and commissions; 3. United States Army Corps of Engineers; 4. Watershed District(s); 5. Metropolitan Government, its agencies, departments and commissions. T. Proof of Title. Upon request, the Developer shall famish the City with evidence satisfactory to the City that it has the authority of the fee owners and contract for deed purchasers to enter into this Development Contract. U. Soil Conditions. The Developer acknowledges that the City makes no representations or warranties as to the condition of the soils on the property or its fitness for construction of the improvements or any other purpose for which the Developer may make use of such property. The Developer further agrees that it will indemnify, defend, and hold harmless the City, its governing body members, officers, and employees from any claims or actions arising out of the presence, if any, of hazardous wastes or pollutants on the property, unless hazardous wastes or pollutants were caused to be there by the City. V. Soil Correction. The Developer shall be responsible for soil correction work on the property. The City makes no representation to the Developer concerning the nature of suitability of soils nor the cost of correcting any unsuitable soil conditions which may exist. On lots which have no fill material a soils report from a qualified soils engineer is not required unless the City's building inspection department determines from observation that there may be a soils problem. On lots with fill material that have been mass graded as part of a multi -lot grading project, a satisfactory soils report from a qualified soils engineer shall be provided before the City issues a building permit for the lot. On lots with fill material that have been custom graded, a satisfactory soils report from a qualified soils engineer shall be provided before the City inspects the foundation for a building on the lot. W. Haul Routes. The Developer, the Developer's contractors or subcontractors must submit proposed haul routes for the import or export of soil, construction material, construction equipment or construction debris, or any other purpose. All haul routes must be approved by the City Engineer Cs:�b� X. Develonment Signs. The Developer shall post a six foot by eight foot development sign in accordance with City Detail Plate No. 5313 at each entrance to the project. The sign shall be in place before construction of the required improvements commences and shall be removed when the required improvements are completed, except for the final lift of asphalt on streets. The signs shall contain the following information: project name, name of developer, developer's telephone number and designated contact person, allowed construction hours. Y. Construction Plans. Upon final plat approval, the developer shall provide the City with two complete sets of full-size construction plans and four sets of I1"x17" reduced construction plan sets and three sets of specifications. Within four months after the completion of the utility improvements and base course pavement and before the security is released, the Developer shall supply the City with the following: (1) a complete set of reproducible Mylar as -built plans, (2) two complete full-size sets of blue linelpaper as -built plans, (3) two complete sets of utility tie sheets, (4) location of buried fabric used for soil stabilization, (5) location stationing and swing ties of all utility stubs including draintile cleanouts, (6) bench mark network, (7) digital file of as -built plans in both Axf & .tif format (the Axf file must be tied to the current county coordinate system), (8) digital file of utility tie sheets in either .doc or .tif format, and (9) a breakdown of lineal footage of all utilities installed, including the per lineal foot bid price. The Developer is required to submit the final plat in electronic format. Z. As -Built Lot Surveys. An as -built lot survey will be required on all lots prior to the Certificate of Occupancy being issued. The as -built lot survey must be prepared, signed, and dated by a Registered Land Surveyor. Sod and the bituminous driveways must be installed before the as -built survey is completed. If the weather conditions at the time of the as -built are not conducive to paving the driveway and/or installing sod, a temporary Certificate of Occupancy may be issued and the as -built escrow withheld until all work is complete.

City Council approval requires a majority vote of City Council. EXECUTIVE SUMMARY The applicant is requesting rezoning and subdivision approval to create a 12 lot single-family detached housing residential neighborhood. The proposed variances are from the subdivision ordinance: for the use of a flag/neck lot, cul- de-sac bubble size and for less than 300 feet offset from street centerlines; and from the zoning ordinance for the setback from the cul-de-sac bubble. PLANNING COMMISSION SUMMARY The Planning Commission held a public hearing on May 17, 2016 to review the proposed development. The Planning Commission voted five to one on a motion recommending that City Council approve the development. Issues of concern brought out at the Planning Commission were grading, storm water management and tree preservation. Specifically, there was concem about the creation of wet, rear yard areas through the grading of lots 6 — 9 and the use of retaining walls, and limiting the usability of the yard by the home owner. Staff has seen similar circumstances, The Preserve at Bluff Creek, where the use of retaining walls to alter the site to create lookout and walk out homes resulted in excessively wet conditions to occur. For lots 1 — 5, there was concern that storm water runoff would be greater than currently exists and that off -site discharge under Lake Lucy Road would be greater than currently occurs. There are specific modifications to the grading plan and Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow requirements for additional analysis that should alleviate these concerns and provide answers before that final plat may be approved. Staff would like to be assured that the post development discharge rates and volumes are at or below existing conditions. To address concerns about the western lots, staff has added the following condition, which was discussed as part of the report, but not included as a condition under Engineering: 4. The applicant shall revise lots 6-9 be a full -basement, rambler -style home. This condition should reduce some of the grading on the site, lessen the size or need for retaining walls and be more conforming to the existing land form. The applicant also submitted a "responses to staff recommendations". While they concurred with the majority of the recommended conditions, there were four that they requested be deleted. The discussion, their rational (blue type) and staff responses (red type) are attached to this report. Staff recommends that the conditions remain with modifications to Water Resources condition 3. 3. The stormwater management practices shall achieve a new overall reduction of at least 90% for total suspended solids and 60% for total phosphorous using industry accepted removal rates. This includes manipulation of the NURP50 Particle Distribution filtration efficiencies to match accepted literature values. Finally, the revisions to the plans may provide additional tree preservation opportunities, but staff does not want to accept current preservation if in the future, the home owner will be responsible for removal of the trees. The required grading revisions may provide additional areas that would be acceptable for the planting of trees throughout the development. Planning Commission minutes for May 17, 2016 are included in the consent agenda for the June 13, 2016, City Council packet. RECOMMENDATION Staff recommends approval of the rezoning and preliminary plat with variances for the use of flag lots, cul-de-sac bubble size and a local street centerline offset of less than 300 feet and a building setback variance from the cul-de-sac bubble for lot 11, plans prepared by Stantec, dated 5/6/2016, subject to the conditions of the Planning Commission staff report and adoption of the findings of fact. ATTACHMENTS Letter from Allan & Mary Weingart to City of Chanhassen dated May 17, 2016 Letter from Betsy Randall to City of Chanhassen dated May 18, 2016 Lake Lucy Road Responses to Staff Recommendations dated May 17, 2016 Planning Commission Staff Report Dated May 17, 2016 as revised. ALAN & MARY WEINGART May 17, 2016 TO: City of Chanhassen Chanhassen Planning Commission RE: Yosemite Holding, LLC Rezoning Request 1600 and 1630 Lake Lucy Road Planning Commission Members, Unfortunately, I will be unable to attend tonight's Planning Commission meeting due to a business conflict that has taken me out of town. I lieu of attendance, I wanted to express some concerns regarding the proposed development referenced above. First of all, I am NOT opposed to the development of the indicated property. Landowners have the right, within limits, to do what they want with their own land. The issue I have is when that development has a potential, and in this case likely, detrimental impact on neighboring properties. Mary and I are the owners of a portion of the property directly to the south of the subject development. We, along with the Kendall's and Randall's, own the property noted in the recent staff report as the "Southern Drainage Area". Our own property happens to be the 1800' driveway that extends from Lake Lucy Road out to the 11 acre so-called "island" in Lake Lucy. (We also have our primary residence down Lake Lucy Road and up Steller Court at 1685 Steller Court.) The Southern Drainage Area is made up primarily of wetlands, a portion of which I was required to mitigate when we put our driveway in back in 1999-2000. This is very low property that "holds" water for quite some time after heavy rains and/or snowmelt (when there used to be such a thing!). There is NO DRAINAGE from this basin into Lake Lucy or anywhere else, so the water accumulates and slowly percolates into the wetlands or evaporates ..... the only two options. The staff report makes an interesting observation when it says on page 6 that "Regardless of which path the drainage takes relative to the driveway; it all ends up in a third wetland with no constructed outlet although it appears that it does drain overland to Lake Lucy if it bounces approximately five (5) feet." (emphasis added). "Bounces .... 5... feet? I suspect that this is a technical engineering term of art, but I have never seen this occur in this area nor can I imagine such happening. I do, however, agree that the water would need to rise in that wetland basin about 5 feet BEFORE it would begin to make its way to Lake Lucy. AND, if that were the case, my driveway would be under water about 4'/z feet, along with the Kendall's home being partially flooded! The point being made here is that the prospect for southerly discharge of water is quite detrimental to the property owners that I have mentioned, and I would propose that our driveway would be the first property negatively impacted by such discharge. This potential for standing water that covers or degrades my driveway at the lowest point through these wetlands seriously impacts the value of my island property as it is the only means of reaching that 11 acre parcel. The staff report attempts to address the mitigation of this problem, but, in my opinion, raises more concerns than it resolves. The division of the development into "two major drainage area(s)" creates a significant area from which water will flow into the Southern Drainage Area. Some particularly troubling statements from the report are as follows: 1685 STELLER COURT, EXCELSIOR, MN 55331 Telephone: Work: (612) 376 4005 Mobile: (952) 239 5899 Home: (952) 474 6884 Email: Work: aweingart@doughertymarkets.com Home: alweingart@vi_9 com ALAN & MARY WEINGART ■ Page 6: When addressing my driveway, the report states, "nor does it appear designed to city standards." When I put this driveway in, it was certainly vetted and approved by the City and about 15 other state and federal agencies. Please review the records as this was not a renegade homeowner acting on his own! ■ Page 6: "Staff agrees that the lack of easement and infrastructure makes it untenable to send any additional runoff to the south. These property owners should not bear the responsibility for the stormwater management of the subject property." ■ Page 6: "The development of the site must not direct any additional volume of runoff to the south. Further, rates must not be increased over existing rates for any scenario." ■ Page 6: "The current plan...... still directs the majority of lots 1 through 7 to the south." ■ Page 6: Apparently, one solution is to "employ downspouts" to assist in the direction of the roof drainage to the north. Who is going to police this once the development is done? The staff report even questions this on page 7 when they add, "While this could work in principal, the practice of this will be difficult [to] implement, inspect and compel compliance." ■ Page 7: All of this leads staff to conclude that it is highly unlikely that more water is not being directed south than is claimed." ■ Page 7: "It is intuitive that a site, after mass grading, will be more compacted than under current conditions. Mass graded sites intentionally compact soils to increase strength for paved areas and building pads. This increase in compaction leads to an increase in bulk density and a decrease in soil porosity. This translates into an increase in the volume of water running off the site." These are just a few of the statements that staff has made throughout their thorough report that question the southerly flow of stormwater discharge and how this problem is being mitigated. The only potential solution that I can envision (and I am not an expert on these matters) is for the stormwater to be diverted: 1. To the eastern wetlands as is being proposed for the northern section of this development, 2. Through Pheasant Hills Park to the wetlands on the southerly side of that park north of Lake Lucy Lane, or 3. Down Lake Lucy Road to the west so that it ultimately drains into the wetlands to the west of Steller Court (admittedly, a difficult redirection). Having the stormwater from roughly half of this development flow to the Southern Drainage Area with no interruption (not even a holding pond) will be significantly detrimental to my property, and that of my neighbors, as well. And, any monitoring of this once the development has been done will be virtually impossible and unenforceable. Once again, I apologize for not being able to attend the May 17" Planning Commission meeting, but hope you will take our concerns under consideration in your assessment of this development. Thank you for your time and commitment to the City of Chanhassen as your task is not an easy one. Regards, 4��, 1685 STELLER COURT, EXCELSIOR, MN 55331 Telephone. Work: (612) 376 4005 Mobile: (952) 239 5899 Home: (952) 474 6884 Email: Work: aweingart�Jodoughertymarketscom Home: alweingart@visi.com May 18, 2016 To: City of Chanhassen Chanhassen Planning Commission Chanhassen City Council Re: Yosemite Holding, LLC Rezoning Request 1600 and 1630 Lake Lucy Road Planning Commission and Council Members, I attended the meeting Tuesday (5/17/16) evening and realized there was more that needed to be stated about my concerns regarding the drainage from the above rezoning and subdivision. The 100 year rain was mentioned by staff at the meeting last evening which I believe was stated at 6" in 24 hours, this seems to be happening more often than once in a 100 years. There have been many times in the past and will be more in the future when we get more than that in a few days of steady rain. Last fall (Oct. -Nov 2014) we received more than 6" in a few days of constant rain. My property received so much water that I could have had a skating pond over the winter on the area where the water ponds on the north side of my property. This "pond" greatly exceeded the "normal' high water markers placed on my property years ago. How can the currently proposed plat NOT increase drainage onto my and the adjoining properties when especially since the developer states they will have to haul in many tons of earth to do the proposed building of these homes. The current soil is basically clay which causes a lot of runoff so what type of soil will be brought in to reduce this? Staff mentions packing of the soil on the property as a concern. If soil compaction is done in the "usual' way it will be packed to densely and increase more drainage to the south. How will this be monitored or dealt with? Looking at the latest elevations (pages 4 and 6 of commission packet) of lots 1- 6 and possibly 7 the runoff to the south can only be more than present. How will the drainage be monitored to make sure it is not more than what currently drains south? Since there is no direct drain to Lake Lucy from mine or neighbor properties when the water has nowhere to go it backs up onto my property. There have been times in the 20 years I have owned this property that the northern part of my property has been basically inaccessible due to the amount of moisture there. This may be great to drown the wild garlic but also great for the mosquito population. I would like to see a comparison of the existing elevations compared to the proposed elevations for this project and have someone explain to my neighbors and me how the drainage to the south from current proposed preliminary plat will NOT increase due to the change. I will be out of town for the next few days but would like to take this opportunity to invite the council members, staff and whomever to come walk the properties on the south side of Lake Lucy Road after Memorial Day to really SEE the problem that could be caused if drainage into this area is increased at all! Bring your water boots... Sincerely, L2c:� Betsy (Kathryn) Randall 1571 Lake Lucy Road 952-474-6522 LAKE LUCY ROAD; NEW RESIDENTIAL NEIGHBORHOOD RESPONSES TO STAFF RECOMMENDATIONS to PRELIMINARY PLAT FLING. Planning Commission Meeting, Tuesday, May 17, 2016 We are in full agreement with 76 of 80 conditions of approval. Following the section labeled RECOMMENDATIONS on Page 19, there are seven topics, with conditions. Seventy six of these conditions are standard and typical of final plats, construction plans and details. We will accommodate all of these requests in our revised plans. Please see our responses to the following 4 conditions: Note —Three of these four items can be accommodated, but we would like to share some comments for your consideration. Because we are concerned that these conditions will either adversely impact environmental quality, impose added cost without any real benefit, we would like these conditions to be discussed, and ideally, removed as conditions of approval. Engineering Recommendation number 14 is a significant concern to us for the reasons described below. "Engineering: Condition 14. Retaining walls and entry monument... shall be relocated outside standard perimeter drainage and utility easement boundaries, excepting the retaining wall on Lots 5 and 6." Developer & Consultant Observation: The positions of the retaining walls on lots 5 and 6 serve the some function of assisting drainage, within the "drainage easements", as do the retaining walls on Lots 8, 9 and 10. The walls on each one of these lots is critical to the proper drainage and runoff flows, as well as sustaining a suitable area for home construction. Significantly, forcing the walls off of drainage easements, (specifically titled for such use), is an exceptional and unusual requirement that will cause harm. This would impose adverse effects on the functions and values of lots and inhibit drainage, while providing no benefits. We, therefore, request that this Engineering Condition #14 be deleted/ This condition will remain. Per Condition 14, the retaining wall on Lots 5 and 6 may stay inside the easement, but will require an encroachment agreement. That retaining wall must be under an encroachment agreement so that it can be removed when the properties to the west connect to the sanitary sewer near the wall. This is discussed further in the Utility Section of the staff report. For the other retaining walls, requiring them to be constructed outside of drainage and utility easements is not an "exceptional" or "unusual" requirement. The purpose of a perimeter drainage and utility easement is to provide an area for public and private utilities to access the lots and to provide a drainage way between the lots and set back from the building pads. The retaining wall locations proposed would inhibit these purposes. Retaining walls are neither drainage conveyances nor utilities and do not belong in a D&U Easement. The wall on Lot 9 is particularly problematic as maintenance of the wall would require encroachment onto Lot 10. The other three conditions we have concerns regarding are the following: We are being asked to move our entrance monument outside the drainage and utility easement. We have successfully placed entrance monuments within these easements throughout the Metropolitan Area. When they are carefully placed where they won't impede reasonable sight triangles these monuments cause neither transportation nor pedestrian safety problems. And, as long as coordination is done with the relevant utility companies, building, grading and landscape contractors, there is neither any interruption of utility lines nor any drainage problems with this placement. This condition will remain. The placement of the entrance monuments, as proposed, would be within a drainage and utility easement that is specifically dedicated for water and sanitary sewer pipe. When the City performs maintenance or replacement of these pipes, the monument would have to be moved at the expense and likely objection of the Homeowners Association. It is unacceptable to place an entrance monument within this drainage and utility easement, regardless of what the developer has done in other cities in the past. Additionally, the city does not permit monument signage within corner site triangles and would require any signage to be moved out of those site triangles. A. "Environmental Resources Condition: 2. All required plantings must be located on private property outside of public right of way..." Developer & Consultant Observation: Creating a new neighborhood provides an opportunity to introduce the trees that have the greatest visual impact on a city; its boulevard -street trees. Excluding street tree planting from a residential neighborhood's boulevards causes a loss of beauty, and future value gains, at the minor and marginal benefit of potentially, lower maintenance. We understand the value of some limitations on planting with regard to a main collector such as Lake Lucy Road. However, the accepted and typical, well vetted detail has street trees centered between the sidewalk and back of curb, or between the property line and back of curb. That is what our planting plan shows. In these times of tight municipal budgets, and the Emerald Ash Borer, the provision of street -boulevard trees, (conforming to city -approved tree species preferences), is a way to further beautify the city, while also improving the long term values, aesthetics and temperature moderations within new Chanhassen neighborhoods... without direct cost to the City. We, therefore, request that this condition #2 be deleted. The condition will remain. Trees planted on private property near the front property line will still provide a 'boulevard tree' feel to the street but be less exposed to damage from snow plow or sweeping operations as well as out of sight line and utility conflicts. B. "Water Resources: Condition 3: "... achieve a new overall reduction of at least 90% of total suspended solids .... This includes manipulation of the NURP50 Particle Distribution". Developer & Consultant Observation: The effect of these changes, (and proposed "manipulations" of generally accepted stormwater software input parameters), would result in multiple stormwater management devices. These would likely result in decreased removal efficiency and increase city maintenance obligations and costs. There is no ordinance standard that requires this requested change. The manipulation of these parameters will not likely advance the total management goals, they simply add redesign costs. We, therefore, request that this condition #3 be deleted. The condition will be modified to read as shown below. "The stormwater management practices shall achieve a net overall reduction of at least 90% for total suspended solids and 60% for total phosphorous using industry accepted removal rates. This includes manipulation of the NURP50 Particle Distribution filtration efficiencies to match accepted literature values." The condition was misstated. The NURP particle distribution remains unchanged. What must change is the efficiency with which the particle removals will occur. The default removal efficiencies assume that 100'% of the water is infiltrated to the water table. The proposed systems are designed to have a piped outlet (underdrain and/or surface flow) meaning there will be little to no infiltration. As such, the assumed removal efficiencies are incorrect and are incongruent with accepted literature values and overstate the removal of phosphorous and particulates from the runoff. Code requires that water quality standards of 90%TSS and 60% TP reduction are met. Section 19-144 reads as follows: (3) Newly constructed or modified detention basins shall provide storage volume below the outlet (dead storage) to allow for water quality treatment in accordance with the following, whichever is most restrictive: a. Water quality features meeting the MPCA NPDES construction permit for permanent stormwater management systems: b. Water quality treatment consistent with NURP criteria (90 percent removal of TSS and 60 percent removal of TP for a standard NURP particle size distribution) C. "Water Resources: 18: Efforts shall be made to raise the elevations of Lots 2 through 5 to assure positive flow towards the street and ultimately to the treatment devices. Developer & Consultant Observation: The grading design on the preliminary plat shows a graded pad that is larger than the actual home footprint. In any event, the grading design shows water being conveyed both to the street and, via side yards, to the rear yard and drainage swales. This is a common practice, and positive drainage will be provided. Building Requirement #4 on pg. 19, ensures that final grading plans for each lot and home will be in conformance before building permits are issued. The condition will remain. As presented, the high point is at the front of the building pads on the grading plan. As such, only the front yards will be directed towards the street. The remainder of the lots will discharge to the rear towards the area in question south of Lake Lucy Road. This is a development level issue and not a responsibility to be borne by the builder. In fact, it may be too late at that time to address drainage concerns. If the indicated pad size is the issue then I would suggest altering the pad size to accommodate the anticipated home. The watershed draining to the south must not only be limited to the greatest extent practicable but the assumed drainage areas must match what the proposed grading plan shows. �� t r M1 H a � CITY OF CHANHASSEN PROPOSED MOTION: PC DATE: May 17, 2016 C— CC DATE: June 13, 2016 REVIEW DEADLINE: July 30, 2016 CASE #: 2016-09 BY: RG, TH, TJ, ML, JM, JS, SS "The Chanhassen Planning Commission recommends that City Council approve rezoning of the property from Rural Residential, RR, to Single -Family Residential, RSF and preliminary plat approval for 12 lots, one outlot and public right-of-way with variances for the use of flag lots, cul- de-sac bubble size and a local street centerline offset of less than 300 feet and a building setback variance from the cul-de-sac bubble for lot 11 subject to the conditions of approval and adopts the findings of fact and recommendation." SUMMARY OF REQUEST: Rezoning from Rural Residential District (RR) to Single -Family Residential District (RSF), and preliminary plat with variances for a 12-lot single-family residential subdivision.

LEVEL OF CITY DISCRETION IN DECISION -MAKING: The city has a relatively high level of discretion in approving Rezonings because the city is acting in its legislative or policy - making capacity. A rezoning must be consistent with the city's Comprehensive Plan. The city's discretion in approving or denying a Preliminary Plat is limited to whether or not the proposed plat meets the standards outlined in the Subdivision Regulations and Zoning Ordinance. If it meets these standards, the city must approve the preliminary plat. This is a quasi-judicial decision. The city's discretion in approving or denying a Variance is limited to whether or not the proposed project meets the standards in the Subdivision Ordinance for a variance. The city has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi-judicial decision. Notice of this public hearing has been mailed to all property owners within 500 feet. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 2 of 24 PROPOSAL/SUMMARY The applicant is requesting rezoning and subdivision approval to create a 12 lot single-family detached housing residential neighborhood. The proposed variances are from the subdivision ordinance: for the use of a flag/neck lot and for less than 300 feet offset from street centerlines. APPLICABLE REGULATIONS Chapter 18, Subdivisions Chapter 19, Water, Sewers and Sewage Disposal Chapter 20, Article XLI, "RSF" Single Family Residential District BACKGROUND The houses on the site were built in 1981 and 1961. Lake Lucy road was reconstructed as part of the 2005 Street reconstruction project. Site Constraints The high point on the property is in the northwest comer of the site with an elevation of 1032. The low point on the property is along the south property line at the culvert under Lake Lucy Road with an elevation of 994. The site contains two wetlands totaling 0.75 acres which are located in the north central and east central portions of the property. The site has a net canopy coverage of 65.5 percent. REZONING Alternatives The existing zoning of the property, Rural Residential, is not consistent with the land use designation of the property, Residential Low Density. The comprehensive plan allows less intensive land uses to remain in place. However, any approval by the city for development of the property must be consistent with the comprehensive plan. The following zoning districts would be consistent with a Residential Low Density land use: Single -Family Residential (RSF), Mixed Low Density Residential (R-4), Low and Medium Density Residential (RLM), and Planned Unit Development — Residential (PUD-R). The RSF district is the most appropriate zoning district to rezone this property since it is the same zoning as the surrounding residential properties and permits only single-family homes. While the R-4 district permits single-family homes, it also permits twin homes which would be inconsistent with the surrounding development. The RLM district permits single-family homes, as well as twin homes, townhouses and attached housing. But the RLM district also requires that large areas of upland be preserved or created as permanent open space to balance the higher hard surface coverage permitted on the individual lots. Finally, the PUD-R district can be created for a single-family subdivision, Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 3 of 24 but the PUD-R is intended to provide a reasonable and verifiable exchange or benefit to the community that is normally not accommodated through other zoning districts, e.g., enhanced environmental protection, affordable housing and enhanced quality of development. Staff is recommending the rezoning to RSF be approved. Comprehensive Plan Consistency The RSF zoning district is consistent with the Residential Low Density land use designation. The proposed rezoning assists in the furtherance of the following land use goals of the City of Chanhassen Comprehensive Plan: • Development will be encouraged within the MUSA line. The plan should seek to establish sufficient land to provide a full range of housing opportunities. Development should be phased in accordance with the ability of the city to provide services. The proposed rezoning assists in the furtherance of the following housing goals of the City of Chanhassen Comprehensive Plan: • A balanced housing supply with housing available for people of all income levels. • A variety of housing types for people in all stages of the life -cycle. The applicant is proposing a 12 lot single-family detached housing subdivision and two outlots served via public streets with a variance for the use of flag lots for lots 5, 8 and 9 and a variance for less than 300 feet offset from street centerlines. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 4 of 24 PRELIMINARY PLAT SITE CONSTRAINTS Wetland Protection The City of Chanhassen Wetland Inventory and the Minnehaha Creek Watershed Wetland Inventory both indicate the presence of two wetlands on the subject property. Sambatek reviewed and delineated the site in October of 2015. Staff reviewed and approved the delineation that same fall. The notice of decision was mailed on November 17, 2015. The applicant provided MNRAM and determined the northerly wetland to be manage classification 2 and the easterly wetland to be manage classification 1 requiring a 20 foot and 25-foot buffer respectively. Both wetlands require a 30 setback from the buffer for the principal structure. The plans show the appropriate buffers and setback. It is the City's practice to have wetlands and buffers placed into outlots to implement the no net loss goal. The city requires that all runoff is treated prior to discharge into a wetland. Treatment practices are being proposed for much of the drainage being directed to the wetlands. It is proposed that lots 8, 9 and 10 as well as the backs of lots 11 and 12 be treated via the wetland buffer. In those cases, where no other treatment opportunities are available filter strips may be utilized. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 5 of 24 The upland area between the two wetlands will need to be graded to allow for the bounce from the northern wetland to spill over into the eastern wetland. Work will also be required adjacent to the wetland area to install the outlet pipe under Yosemite. The SWPPP must address the potential for wetland impact and how impacts will be avoided. No materials or staging can occur within the wetland area. Any disturbed area within the buffers must be revegetated with native vegetation and a vegetation establishment plan must be provided. Bluff Protection There are no bluffs on the property. Shoreland Management The property lies approximately 225 feet beyond the shoreland overlay district for Lake Lucy. As such it will not be subject to shoreland requirements for land development. Floodplain Overlay This property does not lie with a floodplain. GRADING, DRAINAGE & EROSION CONTROL Site Grading: Drainage Under existing conditions, the site is divided into two major drainage area. A line that extends approximately from the southeast property comer to 150 feet south of the northwest comer divides the drainage areas. Everything north and east of that divide drains to one of two wetlands and is ultimately directed to the east through a new culvert to be installed under Yosemite. Southern Drainage Area Everything south and west of this divide drains to the south towards Lake Lucy. The drainage leaves the site via a culvert that goes under Lake Lucy Road and discharges onto private property to the south. The drainage then either goes through a twelve inch (12") corrugated metal pipe culvert under the private driveway which leads to the island on Lake Lucy or portion of the drainage travels past the culvert and follows an incised ditch along the drive to a wetland located on private property. A second twelve -inch (12") CMP culvert goes under the same drive at this location and appears to equilibrate the wetland with another wetland on the other side of the drive. It appears the drive at this Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 6 of 24 location is the low spot for the area and is prone to overtopping. Regardless of which path the drainage takes relative to the driveway; it all ends up in a third wetland with no constructed outlet although it appears that it does drain overland to Lake Lucy if it bounces approximately five (5) feet. None of this conveyance is under city easement nor does it appear designed to city standards. Staff has received email and voice correspondence from owners of four of the properties to the south that already receive runoff from the subject property. They all expressed great concern over directing additional runoff to the south. Staff agrees that the lack of easement and infrastructure makes it untenable to send any additional runoff to the south. These property owners should not bear responsibility for the stormwater management of the subject property. The development of this site must not direct any additional volume of runoff to the south. Further, rates must not be increased over existing rates for any scenario. The applicant must demonstrate to staff's satisfaction that this condition is met. The current plan iteration does reduce the drainage area but still directs the majority of lots 1 through 7 to the south. This area is currently wooded with two houses and a small lawn area. Under proposed conditions, the area will be mass graded and will be dominated by shallow rooted Kentucky bluegrass and roof. It appears rates can be addressed with the proposed southern management practice but volumes are still suspect. The high points of lots 1 through 4 are at the front of the building. The high point of lot 5 is at the north east corner of the building envelope. This means that in these lots, everything from the front of the building envelope to the back yards drains to the south. In an effort to direct more of the roof drainage north and away from the affected properties to the south, the applicant is proposing to employ down spouts to aide in this conveyance. This was discussed with staff at a meeting as a possible solution. � •. . II� �1 1 -�I Wn 1147 Iq WO MFF7Q22,66 wp B ' ; ! �'0./.

Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 7 of 24 While this could work in principal, the practice of this will be difficult implement, inspect and compel compliance. In addition to enforcing compliance, it may be problematic depending upon the house design. Property owners may also look at the drainage feature in the backyard and feel that it is a more appropriate area to direct their roof runoff. All of this leads staff to conclude that it is highly unlikely that more water is not being directed south than is claimed. In addition, staff does not agree with the assumptions used to determine the composite curve numbers. It is intuitive that a site, after mass grading, will be more compacted than under current conditions. Mass graded sites intentionally compact soils to increase strength for paved areas and building pads. This increase in compaction leads to an increase in bulk density and a decrease in soil porosity. This translates into an increase in the volume of water running off the site. The submittal assumed that bulk densities would remain the same after completion of mass grading as they are under the current conditions. Without a soil management plan indicating how bulk density will be reduced after completion of grading, staff feels this assumption to be erroneous and the composite curve number post development will be significantly higher than under existing conditions. The area should be modeled assuming soils in the C hydrologic group under existing conditions (which matches the published soil survey) and in the D hydrologic group post development. Staff recalculated runoff using assumptions based upon the above discussion and concluded that while it is likely that under the 100 year return frequency events runoff volumes will decrease to the south, volumes will increase under the 10 year return frequency event. The 2 year return frequency event remains has a slight but negligible increase in volumes over existing conditions. The applicant shall revise the plans to assure that there is no increase in runoff rates or volumes to the south. Table 1. Composite Curve Number (CN) Calculation for Existing Conditions.

If the bulk densities are found to be elevated post -development the developer would be responsible for correcting the soils. Cul-de-sac Drainage A low spot exists at the 3 o'clock position on the proposed cul-de-sac. It is staffs preference that this low spot be removed and that positive drainage take place toward the east. The applicant's engineer feels this is not practicable and instead proposed to install a sump manhole at this location to discharge water to the wetland buffer. Drainage of Lots 6-10 In an effort to force look outs onto these lots, several issues are created, including drainage issues. Both lot 7 and lot 8 have drainage shed directly at the structures. This is an unacceptable condition. Because of the swales necessary for conveying water out of the backyards, nearly the entire backyard of lots 6 and 9 will need to be under a drainage and utility easement. This will preclude almost any landscaping as that would have a strong likelihood of creating impoundment conditions on the upstream properties. If these lots were made into full basement units it is possible that less water would be directed south, that greater treatment could be achieved and the likely drainage issues could be avoided. Outlot Drainage The proposed biolfiltration feature has a 100-year high water elevation of 1008.11. It appears that this will bounce into lot 12. Given the nature of this facility, frozen conditions and sediment deposition will decrease the available pore space and can result in increased flood elevations. No emergency overflow has been provided and the plan view does not show the vertical or horizontal placement of the underdrain. The applicant will need to create an overflow between the northern wetland and the southeastern wetland. This must be stabilized and a vegetation restoration plan must be developed. The plans shall indicate that no wetland impacts, including but not limited to the placement of soils and the operation of equipment within the wetland can occur. In addition to the above discussion the following observations were also made pertaining to the grading and drainage plan: Based on the building pads shown, the hardcover area generating stormwater runoff on Lots 1-4 and 6-10 exceed the 25% maximum without taking the driveways into account. Many greatly exceed 25% and go as high as 37% hardcover. The applicant shall include a chart with the maximum hardcover allowed on each lot. The lots shall be graded to drain away from proposed building locations. Spot elevations shall be shown on the plans to verify that water will drain away from buildings at the following locations: Lot 6 backyard, Lot 7 backyard, the east side of Lot 1, the highpoint of the side yard of Lot 10. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 9 of 24 Lots 3, 4 and 5 on the southern half of the property show little level back yard area. This may be problematic for future owners of these lots as there is often an expectation to have a level backyard area for recreational use. In the proposed plan, Lots 6-9 have been artificially created as walkouts through construction of three retaining walls 5-9 feet tall and routing stormwater through the center of their backyard at a shallow slope. This will likely be problematic for future owners of these lots as there is often an expectation to have a level, dry backyard area for recreational use. The drainage area shall be covered with a drainage and utility easement which shall preclude the residents from landscaping or construction of sheds or pools in a large portion of their yard. Staff recommends lots 6-9 be a full -basement, rambler -style home, as this would fit better with the grading on surrounding properties and allow the applicant to create more effective drainage for these lots, rather than excavating down and constructing retaining walls to force a walk -out style home onto the lot. The drainage path on the sideyard of Lot 10 is narrow between the building pad and the retaining wall on Lot 9. The applicant shall move the retaining wall out of the perimeter drainage and utility easement so the easement area can function as the drainage way. The grading plan shall be revised to show a spot elevation at the centerline of the driveway where it meets Street A. Draintile is required for all lots where stormwater runoff will flow from the back to the front of the property. Draintile shall be shown on the plans for Lots 6, 7, 8, and 9. The southern basin shows an Emergency Overflow (EOF) onto Lake Lucy Road, a collector roadway. To minimize additional stormwater runoff created by long driveways required for the "flag" or "neck" lot variance, the applicant's plans show proposed 10-foot driveways for the length of the "neck". The applicant shall identify the discharge point of the culvert shown on the existing topography near the existing driveway of 1600 Lake Lucy Road. If it is a driveway culvert, the applicant shall have it removed or bulkhead and abandoned. Erosion Prevention and Sediment Control The proposed development will exceed one (1) acre of disturbance and will, therefore, be subject to the General Permit Authorization to Discharge Stormwater Associated with Construction Activity Under the National Pollution Discharge Elimination/State Disposal System (NPDES Construction Permit). The applicant shall prepare a Surface Water Pollution Prevention Plan (SWPPP) and submit to the city for approval prior to final plat review and approval. The SWPPP is a required submittal element for preliminary plat review. No earth disturbing activities may occur until an approved SWPPP is developed. This SWPPP shall be a standalone document consistent with the NPDES Construction Permit and shall contain all required elements as listed in Parts III and IV of the permit. The city has a checklist which they will make available to the consulting engineer. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 10 of 24 Retaining Walls The applicant has proposed four retaining walls as part of this subdivision. The retaining wall on the western property line of Lot 8 is approximately 55 feet long and 5 feet tall. The wail is approximately 30 feet from the building pad, and the backyard of Lot 8 is below the wall. The north retaining wall on Lot 9 is approximately 110 feet long and 7 feet tall. This wall is approximately 14 feet from the side of the Lot 9 building pad with a drainage swale between the pad the and wall. The sideyard of Lot 9 is below the retaining wall. Staff recommends this wall be eliminated or reduced in size by changing the home style of Lots 8 and 9 to ramblers. (See the grading section for more information about this recommendation.) The retaining wall on the eastern property line of Lot 9 is approximately 80 feet long and 5 feet tall. The building pad of Lot 10 is 12 feet east of the wall and sits below the wall. Top and bottom wall elevations shall be shown for this retaining wall. This wall shall be relocated outside the drainage and utility easement. The retaining wall at the comer of Lots 5 and 6 is approximately 125 feet long and 9 feet tall. The sideyard of Lot 5 and the backyard of Lot 6 are below this wall. This wall crosses the lot line and thus is on both Lot 5 and 6. Any wall that crosses lot lines shall be owned and maintained by a Homeowners Association (HOA). The development plans shall call out the material of the retaining wall. The following materials are prohibited for retaining wall construction: smooth face, poured in place concrete (stamped or patterned is acceptable), masonry, railroad ties and timber. Boulder walls shall not be taller than six feet. STORMWATER MANAGEMENT Article VII, Chapter 19 of City Code describes the required storm water management development standards. Section 19-141 states that "these development standards shall be reflected in plans prepared by developers and/or project proposers in the design and layout of site plans, subdivisions and water management features." These standards include abstraction of runoff and water quality treatment resulting in the removal of 90% total suspended solids (TSS) and 60% total phosphorous (TP). The applicant is proposing the construction of two (2) biofiltration features to treat runoff from a portion of the subject property. The plan, as submitted, does not provide any structural BMPs as stormwater practices to treat the runoff from lots 8 through 10. Instead, the plan will employ a backyard swale and the wetland buffer as a water quality treatment features. The modeled design removal efficiencies for all storm water management practices were considerably greater than the values recognized by the Minnesota Stormwater Manual and other industry standards. In reviewing the input settings for the P8 model, it was observed that the model was left in its default mode which assumes that there is complete infiltration to the water table. That is to say that none of the water leaves the site. This is clearly not the case for these Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 11 of 24 features and, as such, the NURP50 Particle Distribution should be adjusted to more accurately reflect the site conditions and literature values. The applicant must achieve the 90% TSS and 60% TP removal using removal efficiencies recognized as industry standards or otherwise justifiable. On April 27, 2016 staff had a conference call with the consulting engineers for the applicant. They would enhance the functionality of the filtration basins through the incorporation of iron filings, pretreatment devices or some combination thereof. It is proposed that the south filtration basin will be drained through an outlet structure to be constructed which will replace the existing corrugated metal pipe culvert. The water is then picked up by a series of ditches and corrugated metal pipe culverts all under private ownership before discharging into an apparently landlocked basin at 1571 Lake Lucy Road. There is no easement over this basin or the aforementioned conveyance. Staff is concerned that any increase in water volume may have the unintended consequence of creating additional scour conditions and increasing the size of this wetland. Staff is also concerned about performance and maintenance of the conveyance system that is not under City control and has not been modeled hydraulically or hydrologically. These concerns have been discussed with the applicants consulting engineer. They have provided calculations suggesting that they are not increasing rates or volumes to this area. However, as was discussed in the section on drainage, staff is not convinced this is the case. Staff is concerned about the long term viability of the southern biofiltration basin given the location on private property. The applicant will need to prepare an operations and maintenance manual for the features including inspection schedule. The applicant will need to form a Home Owners' Association to assume ownership and responsibility for the maintenance of any landscaping the HOA may wish to have. The city will assume responsibility for the underdrains, refreshing the iron filings and any piped storm sewer conveyance into or out of this feature. The development contract shall reflect this and a drainage and utility easement shall be recorded over the feature and any conveyances. The eastern biofiltration basin will be within an outlot dedicated to the city. The city will assume ownership of this basin upon satisfaction that it has been built to design specifications. Storm Water Utility Connection Charges Section 4-30 of code sets out the fees associated with surface water management. A water quality and water quantity fee are collected with a subdivision. These fees are based on land use type and are intended to reflect the fact that more intense the development type, the greater the degradation of surface water. These fees can be credited up to 50% if the design has a reasonable expectation of achieving abstraction of the first 1.1 inches of runoff from all proposed hardcover on the site. As this development will not be employing any infiltration or re -use practices, no credit will be applied. The wetland and buffer and upland area put into the outlot will be removed from the assessed property. This area is 1.60 acres so the net assessable land area is 7.36 acres. Based upon the area and land use type, the Storm Water Utility Connection Charge is estimated to be $8,000/acre x 7.36 acres = $58,880. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 12 of 24 RIGHT-OF-WAY, STREETS AND EASEMENTS The survey included all easements and right of way shown on the title search of the property dated November 20, 2015 from Stewart Title Guarantee Company. The applicant shall have their survey confirm this with a recent title survey before final plat. The applicant proposes a 60-foot right-of-way over Street A and 60-foot right-of-way radius over the cul-de-sac bubble. The plat maintains the existing, 66-foot right-of-way easements for Lake Lucy Road and Yosemite Avenue. Easements over drainage swales, basins and storm water pipes shall be called out as "Drainage and Utility" easements. Retaining walls and an entry monument are proposed within City easements. These elements shall be relocated outside of the standard perimeter drainage and utility easement boundaries. The retaining wall on Lots 5 and 6 requires an encroachment agreement. The preliminary plat shows a signage easement on Lot 1. This shall be a paper easement between Lot 1 and the development's HOA. Per § 18-78, staff and the applicant examined providing future access for adjacent properties to the west, 1650 and 1670 Lake Lucy Road. However, it is uncertain how these properties would develop in the future and what type of legal encumbrance Lot 5 would require. Staff recommends 1650 and 1670 have access off of Lake Lucy Road when they develop in the future. STREETS, DRIVEWAYS & SIDEWALK The applicant proposes construction of a public street, Street A. The applicant shall name this street with coordination with the Fire Marshall prior to submittal for final plat review. Street A is proposed to City standards at 31 feet wide and using the Chanhassen Standard Detail typical section. The applicant shall include the horizontal alignment tabulation for Street A in the plans. Access to the subdivision from Street A is located south of the southeastern wetland. This location was chosen after examining three locations: off of Lake Lucy Road, Yosemite Avenue north of the wetland, and Yosemite Avenue south of the wetland. The Lake Lucy Road intersection alternative was eliminated because of sight -distance concerns around the curve on Lake Lucy Road and the desire for access control on Lake Lucy Road, a Major Collector roadway. The Yosemite Avenue access north of the wetland was eliminated due to environmental concerns from running a roadway between the two wetlands across their EOF point and future maintenance concerns due to a long road extension that is surround by wetland instead of servicing properties. The applicant is applying for a variance to the requirement of 300-foot spacing between local roads per § 18-57. The access location on Yosemite, south of the wetland reviewed using engineering discretion and the guidelines set forth in the 2030 Comprehensive, the proposed intersection offset seems reasonable as the proposed 12 lot subdivision would generate less Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 13 of 24 traffic than a multiple commercial driveway. The applicant's engineer completed a queuing analysis to confirm that traffic queuing to make a left turn into the proposed development would not affect the function of the Lake Lucy Road & Yosemite Avenue intersection. The developer shall show construction limits for utility work below Yosemite Ave and submit a staging and restoration plan with their final plat submittal. A street light shall be installed at the intersection of Street A and Yosemite Avenue. Driveways shall be shown on the plan in the final plat submittal. Driveways shall be designed to meet all standards in City Code §20-1122. To minimize additional stormwater runoff created by long driveways required for the "flag" or "neck" lot variance, the applicant's plan propose 10- foot driveways for the length of the "neck". The sidewalk does not continue north of Street A, therefore the pedestrian ramp at the intersection of Street A and Yosemite Avenue is not required. The pedestrian ramp on the northwest comer of the intersection of Lake Lucy Road and Yosemite Avenue shall be replaced per City of Chanhassen Standard Detail Plates. UTILITIES Sanitary Sewer The applicant proposes an 8" PVC sanitary sewer main to be owned and maintained by the City, due to the elevation of the adjacent sanitary sewer system on the east side of Yosemite, sanitary sewer for this subdivision does not meet the minimum depth required without insulation. The sanitary sewer pipe shall be insulated wherever it is less than 6 feet deep. The sanitary services may also need insulation. The proposed shallow elevation of the sanitary sewer also necessitates Lot 1-4, 11, 12 to use a private, in -home grinder system to pump waste to the public sanitary main which is a gravity flow system. The portion of the grinder pump services that lies within the right-of-way shall be gravity -flowing. Staff recommends the applicant examine at moving the sanitary service on Lot 12 further east to make a gravity service functional. Per § 18-78, the applicant proposes to install sanitary sewer main to the western property boundary to provide future extension to the adjacent properties: 1650 and 1670 Lake Lucy Road. It is unlikely they would be able to connect a gravity system to the sanitary main extension and would likely require private grinder pump systems. The retaining wall would need to be removed at the time of connection to the adjacent properties at the connecting parry's expense. The sanitary sewer/water main crossing on Lot 1 may be in conflict. The applicant's engineer shall verify this when the utility profiles are drafted. SMH 5 shall be moved to be centered between the building pads for Lots 5 and 6. The sanitary services within the cul-de-sac bubble shall be revised to eliminate bends and cleanouts within the right-of-way. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 14 of 24 The utility plan sheet shall be revised to call out the City of Chanhassen as the local authority in Note 13. Water main The applicant proposes an 8" water main system. The plans shall call out C900 material for the water main pipe. The sanitary sewer/water main crossing on Lot I may be in conflict. The applicant's engineer shall verify this when the utility profiles are drafted. Two additional hydrants shall be installed, one at the intersection of Street A and Yosemite Avenue and one at Station 3+00 of Street A. ASSESSMENTS Water and sewer partial hook-ups are due at the time of final plat. The partial hook-up fees will be assessed at the rate in effect at that time. LANDSCAPING AND TREE PRESERVATION I 111 11 v J. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 15 of 24 The following calculations were based on plans dated 4/1/16. Since that time, revisions to the grading plans have been made and not reflected in the tree preservation plans. The applicant must submit a revised tree preservation and landscaping plan before final approval. The applicant for the Lake Lucy Road property development has submitted tree canopy coverage and preservation calculations. They are as follows: Total upland area (excluding wetlands) 7.3 ac. or 318,928 SF Baseline canopy coverage 65% or 208,807 SF Minimum canopy coverage required 46% or 146,706 SF Proposed tree preservation 14% or 45,692 SF. The developer does not meet minimum canopy coverage for the site; therefore, the applicant must bring the canopy coverage on site up to the 46% minimum. The difference between the required coverage and the remaining coverage is multiplied by 1.2 for total area to be replaced. One tree is valued at 1,089 SF. Minimum canopy coverage to be replaced 121,216 SF Total number of trees to be planted II I trees The applicant has proposed a total of 66 trees, located in the front yard of each lot and in the bufferyards. Ordinance requires that at least 75% of the required trees be overstory species. The applicant has proposed 50 overstory trees. To meet minimum requirements at least 83 trees shall be overstory and the remainder can be understory species. The applicant is required to provide bufferyard plantings along Lake Lucy Road. Bufferyard requirements are as shown in the table: Landscaping Item Required Proposed Bufferyard B — South 10 overstory trees 7 overstory trees property line, Lake Lucy 21 understory trees 30 understory trees Rd., 540', 15' width 32 shrubs 37 shrubs Applicant does not meet bufferyard landscaping requirements for overstory trees. The applicant shall meet minimum requirements for bufferyard plantings. PARKS & RECREATION The site is adjacent to Pheasant Hill Park on its western border. This adjoining neighborhood park is 10.87 acres in size and was acquired by the city in 1990. COMPREHENSIVE PLAN — PARKS AND OPEN SPACE The quality and number of recreational facilities in a community directly contributes to its quality of life. For this reason, the City of Chanhassen places a strong emphasis on parks and open space. As the City of Chanhassen has developed and increased in population, more pressure and attention has Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 16 of 24 been given to providing recreational opportunities for our residents. Increased leisure time, health awareness, greater mobility, and high disposable incomes have all contributed to the increased demand for recreational activities. The challenge of the next century will be to provide facilities for a growing and diverse population. Parks can be defined as public areas that provide active or passive -oriented recreational facilities. A significant characteristic of parkland is its accessibility to its users. Open space is any parcel that is not used for buildings or other structures and is left in a natural state. Parks and open space perform diverse functions such as meeting physical and psychological needs, enhancing and protecting the resource base, enhancing real estate values, and providing a positive impact on economic development. COMPREHENSIVE PARK PLAN The city's comprehensive park plan calls for a neighborhood park to be located within one-half mile of every residence in the city. Pheasant Hill Neighborhood Park is located immediately to the west of the proposed subdivision. Pheasant Hill Park, at almost 11 acres in size, offers both passive and active recreation space in addition to extensive natural open spaces. The park features a children's playground, half -court basketball, open play field, picnic shelter, and neighborhood trail connections. Area residents will gain access from Street "A" to Pheasant Hill Park from a developer installed 8- foot wide pedestrian trail that will be maintained by the city and open throughout the year. Additional acquisition of public open space through the application of park dedication requirements is not recommended as a condition of the subdivision. COMPREHENSIVE TRAIL PLAN Residents purchasing homes within the new subdivision will have convenient access to the Lake Lucy Road pedestrian trail via a developer installed public sidewalk to be located on the eastern border of Lot 1. Construction of additional sections of the city's comprehensive trail plan is not recommended as a condition of the subdivision. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 17 of 24 MISCELLANEOUS Applicant must submit proposed street name to Chanhassen Building Official and Chanhassen Fire Marshal for review and approval. Two addition fire hydrants will be required: one at the south/west corner of Yosemite and Street "A" and the second one on the south side of street "A" by Sta.3+00. A three-foot clear space shall be maintained around fire hydrants. Street sign(s) (temporary allowed) shall be installed prior to building permits being issued. Fire Marshal must approve signage. Prior to combustible home construction fire apparatus access roads capable of supporting the weight of fire apparatus shall be made serviceable. An additional address number will be required for lot #9. Its location shall be at the entrance of the private driveway. Sign location and size must be approved by the Fire Marshal. Prior to combustible construction fire hydrants shall be made serviceable. No burning permits will be issued for tree/ brush removal. The applicant must provide a 1:200 "clean" plat drawing. Demolition permits required for the removal of any existing structures. Buildings may be required to be designed by an architect and/or engineer as determined by the Building Official. A final grading plan and soils report must be submitted to the Inspections Division before permits can be issued. Retaining walls over four feet high require a permit and must be designed by a professional engineer. Each lot must be provided with separate sewer and water services. The applicant and or their agent shall meet with the Inspections Division as early as possible to discuss plan review and permit procedures. COMPLIANCE TABLE Area (sq. ft.) Width (ft.) Depth (ft.)

The applicant's variance request is for the use of flag lots and a local street centerline offset of less than 300 feet. Flag lots may be permitted in residential districts with a density of less than four units per acre, if the criteria in variance Section 18-22 are met and upon consideration of the following: (1) The prevailing development pattern makes it unfeasible or inappropriate to construct a public/private street. In making this determination, the city may consider the location of existing property lines and homes, local or geographic conditions and the existence of wetlands. A separate street to access individual lots would add significantly to site hard cover and would not increase accessibility. (2) After reviewing the surrounding area, it is concluded that an extension of the public or a private street system is not required to serve other parcels in the area, improve access, or to provide a street system consistent with the comprehensive plan. Public street extension is not necessary to access properties to either the north or west. (3) The use of a flag lot will permit enhanced protection of the city's natural resources, including wetlands and protected areas. As an enhancement for environmental protection, the applicant shall include the northeast portion of proposed Lot 12 in one outlot to encompass both the wetlands and the tree preservation area. It should be noted that the Shadow Ridge development, approximately 350 feet east of this development, was developed with the use of flag lots in a very similar configuration to the proposed development: a cul-de-sac street with one curve and a wetland off one side of the cul- de-sac bubble. Section 18-57 requires that local street centerline offset of 300 feet. The local street centerline offset of less than 300 feet is due to the location of the wetland on the east side of the development that would not permit the street to be moved father to the north. Staff and the applicant looked at locating the street between the two wetlands, however that alignment had potentially detrimental impacts to the wetlands and resulted in additional site development concerns. Staff is also supporting a variance from the cul-de-sac bubble for Lot 11 to permit the house to encroach within 20 feet of the cul-de-sac right-of-way. The 30 feet setback still applies from the right-of-way not included in the cul-de-sac bubble which projects 50 feet into the lot due to the bubble off -set. This variance in conjunction with the cul-de-sac bubble reduction permits the development to incorporate storm water improvements to the east of lot 12. Additionally, the applicant is requesting that the city designate the east lot line of lot 9 as the front lot line. City code states "The front yard shall be the lot line nearest the public right-of-way that provides access to the parcel". However, this configuration would require that they create a lot layout and house orientation that would not be in keeping with the house placement on lots 6 through 8 and would create a long and thin, 40 wide, building pad. The city may as part of the variance request designate appropriate house pad configurations. Planning Commission 1600 & 1630 Lake Lucy Road May 17, 2016 Page 19 of 24 Ili u11 uIW 1 4:11YC07� Staff recommends that the Planning Commission approve the rezoning and preliminary plat with variances for the use of flag lots, cul-de-sac bubble size and a local street centerline offset of less than 300 feet and a building setback variance from the cul-de-sac bubble for lot 11, plans prepared by Stantec, dated 5/6/2016, subject to the following conditions and adoption of the findings of fact and recommendation: Buildine: 1.

Public Hearing Notice and Mailing List gAplan\2016 planning cases12016-09 lake lucy rd\swff report lake lucy rd sub.doc CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA FINDINGS OF FACT AND RECOMMENDATION Application of Yosemite Holding, LLC, Almond & Carolyn Krueger and Craig & Deanna Claybaugh for rezoning, subdivision approval with variances from the subdivision requirements. On May 17, 2016, the Chanhassen Planning Commission met at its regularly scheduled meeting to consider the application of Yosemite Holding, LLC, Almond & Carolyn Krueger and Craig & Deanna Claybaugh for rezoning of the property to Single -Family Residential District, preliminary plat approval of property in to 12 lots and two outlots with variances for the use of flag lots, cul-de-sac bubble size and a local street centerline offset of less than 300 feet and a building setback variance from the cul-de-sac bubble for lot 11. The Planning Commission conducted a public hearing on the proposed subdivision preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT 1. The property is currently zoned Rural Residential District, RR. 2. The property is guided in the Land Use Plan for Residential Low Density uses. 3. The legal description of the property is: See Exhibit A_ 4. The Zoning Ordinance directs the Planning Commission to consider six (6) possible adverse effects of the proposed amendment. The six (6) affects and our findings regarding them are: a. The proposed action has been considered in relation to the specific policies and provisions of and has been found to be consistent with the official City Comprehensive Plan. b. The proposed use is or will be compatible with the present and future land uses of the area. c. The proposed use conforms with all performance standards contained in the Zoning Ordinance. d. The proposed use will not tend to or actually depreciate the area in which it is proposed. e. The proposed use can be accommodated with existing public services and will not overburden the city's service capacity. f. Traffic generation by the proposed use is within capabilities of streets serving the property. 5. The Subdivision Ordinance directs the Planning Commission to consider seven possible adverse effects of the proposed subdivision. The seven (7) affects and our findings regarding them are: a. The proposed subdivision is consistent with the zoning ordinance and complies with all the district regulations and requirements; b. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city's comprehensive plan by creating single-family lots within the density ranges required by the comprehensive plan; c. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and storm water drainage are suitable for the proposed development; d. The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; e. The proposed subdivision will not cause environmental damage; f. The proposed subdivision will not conflict with easements of record; and g. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: 1). Lack of adequate storm water drainage. 2). Lack of adequate roads. 3). Lack of adequate sanitary sewer systems. 4). Lack of adequate off -site public improvements or support systems. 6. The city council may grant a variance from the regulations contained in the subdivision ordinance as part of the plat approval process following a finding that all of the following conditions exist: a. The hardship is not a mere inconvenience, but allows for the logical configuration of the lots and also avoids negative impacts to the wetland; b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land, due to the existing parcel configuration, wetlands and site topography; c. The condition or conditions upon which the request is based are unique and not generally applicable to other property since the city directed that the street access be from Yosemite; d. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of the subdivision ordinance, the zoning ordinance and comprehensive plan. Variance Findings — Section 20-58 of the City Code provides the following criteria for the granting of a variance: a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the comprehensive plan. Finding: The construction of a single-family home on the site is permitted in the Single - Family Residential District. The need to provide relief from the setback at the bubble is due to the offset of the cul-de-sac and the storm water management which is being accommodated on the east side of the development adjacent to the wetlands. b. When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties," as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding: The buildable area of the lot is significantly limited by the required setback from the cul-de-sac bubble which is offset into the lot. The property owner proposes to construct a single-family home and driveway. The buildable area on the property has created a practical difficulty for using the site in a reasonable manner, which requires limited relief from city code. c. That the purpose of the variation is not based upon economic considerations alone. Finding: The purpose of the variance is not based on economic considerations alone. The applicant would like to construct a single-family home and driveway on the in a residential zoning district. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The location of the wetlands and storm water pond and the offset of the cul-de- sac bubble creates a unique circumstance for the property to work around when attempting to construct a single-family home on the lot. The required setback from the cul-de-sac bubble creates a narrowing of the buildable area on the lot. e. The variance, if granted, will not alter the essential character of the locality. Finding: The home located on this property will comply with all other setback requirements. Granting the proposed variance request will not alter the essential character of the locality of the Lake Lucy Road neighborhood. f. Variances shall be granted for earth sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This criteria does not apply. 8. The planning report #2016-09 dated May 17, 2016, prepared by Robert Generous, et al, is incorporated herein. RECOMMENDATION The Planning Commission recommends that the City Council approve the Rezoning, Preliminary Plat with Variances for the use of flag lots and less than 300 feet street offset subject to the conditions of the staff report.

File: 193803412 Date: February 25, 2016 Reference: Lake Lucy Road & Yosemite Avenue Housing Development Queueing Study INTRODUCTION A development consisting of 12 single family homes has been proposed to be built in the city of Chanhassen, MN near the intersection of Lake Lucy Road and Yosemite Avenue. Access to the new development will be off of Yosemite Avenue. Due to the proximity of the entrance for the new development to the intersection at Lake Lucy Road and Yosemite Avenue, there is concern that vehicles may queue back to the intersection. Stantec has been asked to investigate the potential for queueing of vehicles attempting to enter the new development on Yosemite Avenue. METHODOLOGY COUNTS Stantec performed turning movement counts (TMC) at the intersection of Lake Lucy Road and Yosemite Avenue on the afternoon of Wednesday, February 25, 2016 from 4:00-6:00 PM. It was determined that only PM peak counts would be required, as that is the time when the most vehicles would attempt to turn into the development. The counts taken were seasonally adjusted according to MnDOT standards. TRIP GENERATION Trip generation was performed using the ITE Trip Generation Manual 9th Edition. The results can be seen in Table 1 below. To simulate the maximum amount of strain on the system, and create the most potential for queues to develop, all vehicles entering the development were set to originate from Lake Lucy Road. Design with cormKmity in mind mp c.\users\mtp ..\de J.P\c ho \qu .hg tech memo.tl ® Stantec February 25, 2016 Stephanie Smith, PE Page 2 of 2 Reference: Lake Lucy Road 3 Yosemite Avenue Housing Development Queueing Study FORECASTING Analysis was performed for the year 2036. The MnDOT traffic projection factor for Carver County is currently 1.4. This factor was applied uniformly to all turning movement counts. SIMULATION The 2036 analysis was performed using the software Synchro/SimTraffic 9. The results of the simulation from this software provide the projected queueing data required to determine if any problems could potentially arise by the year 2036. RESULTS The results of the simulation showed no problems with queueing at the new intersection. The maximum queue observed in simulation was 18' in length or roughly two cars. The 95th percentile queue was 9' or roughly one car. The simulation shows that there should not be a sufficient amount of traffic to create queues reaching back to the Lake Lucy Road and Yosemite Avenue intersection.

We attended the meeting when Terry Forbord explained the project. Our concern is the loss of many beautiful trees. The ash borer is already in Plymouth and will soon become a tragic problem in our city. On this particular property, it is a haven for deer, wild turkeys and other wild life. We hope that the developers will be encouraged to save as many trees as possible. There is a beautiful clump of aspen -like trees on the comer that needs to be saved. If you have not driven by this property, please do and let the developer know that it is important not to destroy these very old and lovely trees. The David Weekley development at the end of our street was clear-cut and we do not want that to be repeated. The final approval of this project is Tuesday, May 3rd.

Where are these retention ponds to drain? There is no direct access to drain to Lake Lucy, currently the water along this section of road drains onto my property which does not have drainage access to Lake Lucy What are the elevations for at least the 5 houses proposed along LLR? That too will cause more runoff onto my property, and a larger breeding ground for mosquitos. I assume since there is not a variance for hard cover on any of the lots that is not an issue but..... can we request storm water safe or permeable paver driveways be installed to cut down on hard cover? Why weren't the neighbors contacted about the Gloccum subdivision before it happened. There was no contact from the city notifying when it was going to the Planning Commission or Council asking us for input, why? Sincerely, Kathryn Randall 1571 Lake Lucy Road 952-474-6522 Sent via iPhone On May 3, 2016, at 9:55 AM, Mary Henderson <mkhendersoni�mchsi.com> wrote: Dear Council, I have been a Chanhassen resident for 23 of the last 26 years and love where I live. Chanhassen has been voted one of the Best Cities to live in numerous times, one of the reasons for this award is it's `wide swaths of open space". However this is ever changing, changing the look and feel of why we Chanhassen's love living here. There has been a 13.68 % growth since 2000, I live in the Minnetonka School District and have seen Excelsior Elementary grow from 500 students in 2005 to over 800 in 2016. They had to downsize the playground to accommodate the cars coming and going onto the school property. There has been a huge expansion of development on West 78th Street, with Galpin continuing development of housing, and a new preschool. Wherever you look the "swaths" of open land are being developed. Small parcels where too many oversized homes are being added. For example The David Weekly Development on Yosemite and Lake Lucy. And now a new proposal to add 12 more homes across the street from there. This is the street I live off of, where Yosemite and Apple Road meet. I walk everyday along Yosemite, dodging cars that cut through to get to the city of Excelsior, HWY 7 and the schools in this area. Yosemite is used more often then Lake Lucy to Powers to access these locations. By adding 12 new homes, at least 24 more vehicles will be driving up and down a road that has no side walk and is very busy. More land will be developed, taking away green space and displacing the many animals we all enjoying seeing. All for what? The value of my 2006 new home construction has actually gone down the last couple of years. Which is very disappointing. I do not see how adding additional homes in this already overbuilt area will benefit the residents that live here. One more thing, with the passing of Prince, now his land might possibly be up for development as well. Bringing in more taxes for Chanhassen, but not good for the residents seeing their home values drop and taxes go up. This is not the reason why I live here, to see every open piece of land to be developed. Please consider this proposed land site not to be developed.

Planning Commission Meeting, Tuesday, May 17, 2016 We are in full agreement with 76 of 80 conditions of approval. Following the section labeled RECOMMENDATIONS on Page 19, there are seven topics, with conditions. Seventy six of these conditions are standard and typical of final plats, construction plans and details. We will accommodate all of these requests in our revised plans. Please see our responses to the following 4 conditions: Note — Three of these four items can be accommodated, but we would like to share some comments for your consideration. Because we are concerned that these conditions will either adversely impact environmental quality, impose added cost without any real benefit, we would like these conditions to be discussed, and ideally, removed as conditions of approval. Engineering Recommendation number 14 is a significant concern to us for the reasons described below. "Engineering: Condition 14. Retaining walls and entry monument... shall be relocated outside standard perimeter drainage and utility easement boundaries, excepting the retaining wall on Lots 5 and 6." Developer & Consultant Observation: The positions of the retaining walls on lots 5 and 6 serve the same function of assisting drainage, within the 'drainage easements" as do the retaining walls on Lots 8, 9 and la The walls on each one of these lots is critical to the proper drainage and runoff flows, as well as sustaining a suitable area for home construction. Significantly, forcing the walls off of drainage easements, (specifically titled for such use), is an exceptional and unusual requirement that will cause harm. This would impose adverse effects on the functions and values of lots and inhibit drainage, while providing no benefits. We, therefore, request that this Engineering Condition #14 be deleted/ The other three conditions we have concerns regarding are the following: We are being asked to move our entrance monument outside the drainage and utility easement. We have successfully placed entrance monuments within these easements throughout the Metropolitan Area. When they are carefully placed where they won't impede reasonable sight triangles these monuments se neither transportation nor pede rian safety problems. a And, as long as coordination is done with the relevant utility companies, building, grading and landscape contractors, there is neither any interruption of utility lines nor any drainage problems with this placement. A. "Environmental Resources Condition: 2. All required plantings must be located on private property outside of public right of way..." Developer & Consultant Observation: Creating a new neighborhood provides an opportunity to introduce the trees that have the greatest visual impact on a city; its boulevard -street trees. Excluding street tree planting from a residential neighborhood's boulevards causes a loss of beauty, and future value gains, at the minor and marginal benefit of potentially, lower maintenance. We understand the value of some limitations on planting with regard to a main collector such as Lake Lucy Road. However, the accepted and typical, well vetted detail has street trees centered between the sidewalk and back of curb, or between the property line and back of curb. That is what our planting plan shows. In these times of tight municipal budgets, and the Emerald Ash Borer, the provision of street -boulevard trees, (conforming to city -approved tree species preferences), is a way to further beautify the city, while also improving the long term values, aesthetics and temperature moderations within new Chanhassen neighborhoods... without direct cost to the City. We, therefore, request that this condition #2 be deleted. B. "Water Resources: Condition 3: "... achieve a new overall reduction of at least 90% of total suspended solids .... This includes manipulation of the NURP50 Particle Distribution'. Developer & Consultant Observation: The effect of these changes, (and proposed "manipulations" of generally accepted stormwater software input parameters), would result in multiple stormwater management devices. These would likely result in decreased removal efficiency and increase city maintenance obligations and costs. There is no ordinance standard that requires this requested change. The manipulation of these parameters will not likely advance the total management goals, they simply add redesign costs. We, therefore, request that this condition #3 be deleted. C. "Water Resources: 18: Efforts shall be made to raise the elevations of Lots 2 through 5 to assure positive flow towards the street and ultimately to the treatment devices. Developer & Consultant Observation: The grading design on the preliminary plat shows a graded pad that is larger than the actual home footprint. In any event the grading design shows water being conveyed both to the street and, via side yards, to the rear yard and drainage swales. This is a common practice, and positive drainage will be provided. Building Requirement #4 on pg. 19, ensures that final grading plans for each lot and home will be in conformance before building permits are issued. Generous, Bob From: Renee Schubbe <Schubbel@msn.com> Sent: Tuesday, May 17, 2016 9:55 AM To: Generous, Bob Subject: Lake Lucy Road Development Hello! I am unable to make it to the Planning Commission Meeting tonight, but wanted to let my view of the proposed development be known. I am opposed to this development and hope that it will not be approved as it stands right now. The proposed destruction of over 200 trees on that lot is unacceptable to me. I watched as the trees were taken down at the David Weekly development across the street from this one, and I was appalled that the city was allowing it. As a private homeowner, I feel that the city would not allow me to take down that many trees on my own property, but seems to have a double -standard when it comes to developers. Even though the developer is proposing to plant new trees, it does not fit with the character of Chanhassen, and especially the area along Lake Lucy Road, to have new, young trees instead of our beautiful mature ones. I hope that the City of Chanhassen, and the Planning Commission, will not approve this development and the proposed destruction of over 200 trees on this lot. Thank you for your time. Sincerely, Renee Schubbe 6550 Shadow Lane Chanhassen, MN ALAN & MARY WEINGART May 17, 2016 TO: City of Chanhassen Chanhassen Planning Commission RE: Yosemite Holding, LLC Rezoning Request 1600 and 1630 Lake Lucy Road Planning Commission Members, Unfortunately, I will be unable to attend tonight's Planning Commission meeting due to a business conflict that has taken me out of town. I lieu of attendance, I wanted to express some concerns regarding the proposed development referenced above. First of all, I am NOT opposed to the development of the indicated property. Landowners have the right, within limits, to do what they want with their own land. The issue I have is when that development has a potential, and in this case likely, detrimental impact on neighboring properties. Mary and I are the owners of a portion of the property directly to the south of the subject development. We, along with the Kendall's and Randall's, own the property noted in the recent staff report as the "Southern Drainage Area". Our own property happens to be the 1800' driveway that extends from Lake Lucy Road out to the 11 acre so-called "island" in Lake Lucy. (We also have our primary residence down Lake Lucy Road and up Steller Court at 1685 Steller Court.) The Southern Drainage Area is made up primarily of wetlands, a portion of which I was required to mitigate when we put our driveway in back in 1999-2000. This is very low property that "holds" water for quite some time after heavy rains and/or snowmelt (when there used to be such a thing!). There is NO DRAINAGE from this basin into Lake Lucy or anywhere else, so the water accumulates and slowly percolates into the wetlands or evaporates ..... the only two options. The staff report makes an interesting observation when it says on page 6 that "Regardless of which path the drainage takes relative to the driveway; it all ends up in a third wetland with no constructed outlet although it appears that it does drain overland to Lake Lucy if it bounces approximately five (5) feet." (emphasis added). "Bounces .... 5... feet? I suspect that this is a technical engineering term of art, but I have never seen this occur in this area nor can I imagine such happening. I do, however, agree that the water would need to rise in that wetland basin about 5 feet BEFORE it would begin to make its way to Lake Lucy. AND, if that were the case, my driveway would be under water about 4'/2 feet, along with the Kendall's home being partially flooded! The point being made here is that the prospect for southerly discharge of water is quite detrimental to the property owners that I have mentioned, and 1 would propose that our driveway would be the first property negatively impacted by such discharge. This potential for standing water that covers or degrades my driveway at the lowest point through these wetlands seriously impacts the value of my island property as it is the only means of reaching that 11 acre parcel. The staff report attempts to address the mitigation of this problem, but, in my opinion, raises more concerns than it resolves. The division of the development into "two major drainage area(s)" creates a significant area from which water will flow into the Southern Drainage Area. Some particularly troubling statements from the report are as follows: 1685 STELLER COURT, EXCELSIOR, MN 55331 Telephone: Work: (612) 376 4005 Mobile: (952) 239 5899 Home: (952) 474 6884 Email: Work: aweingart@doughertymarkets.com Home: alweingartna visi.com ALAN & MARY WEINGART i Page 6: When addressing my driveway, the report states, "nor does it appear designed to city standards." When I put this driveway in, it was certainly vetted and approved by the City and about 15 other state and federal agencies. Please review the records as this was not a renegade homeowner acting on his own! ■ Page 6: "Staff agrees that the lack of easement and infrastructure makes it untenable to send any additional runoff to the south. These property owners should not bear the responsibility for the stormwater management of the subject property." ■ Page 6: "The development of the site must not direct any additional volume of runoff to the south. Further, rates must not be increased over existing rates for any scenario." ■ Page 6: "The current plan...... still directs the majority of lots 1 through 7 to the south." ■ Page 6: Apparently, one solution is to "employ downspouts" to assist in the direction of the roof drainage to the north. Who is going to police this once the development is done? The staff report even questions this on page 7 when they add, "While this could work in principal, the practice of this will be difficult [to] implement, inspect and compel compliance." ■ Page 7: All of this leads staff to conclude that it is highly unlikely that more water is not being directed south than is claimed." ■ Page 7: "It is intuitive that a site, after mass grading, will be more compacted than under current conditions. Mass graded sites intentionally compact soils to increase strength for paved areas and building pads. This increase in compaction leads to an increase in bulk density and a decrease in soil porosity. This translates into an increase in the volume of water running off the site." These are just a few of the statements that staff has made throughout their thorough report that question the southerly flow of stormwater discharge and how this problem is being mitigated. The only potential solution that I can envision (and I am not an expert on these matters) is for the stormwater to be diverted: 1. To the eastern wetlands as is being proposed for the northern section of this development, 2. Through Pheasant Hills Park to the wetlands on the southerly side of that park north of Lake Lucy Lane, or 3. Down Lake Lucy Road to the west so that it ultimately drains into the wetlands to the west of Steller Court (admittedly, a difficult redirection). Having the stormwater from roughly half of this development flow to the Southern Drainage Area with no interruption (not even a holding pond) will be significantly detrimental to my property, and that of my neighbors, as well. And, any monitoring of this once the development has been done will be virtually impossible and unenforceable. Once again, I apologize for not being able to attend the May 17'h Planning Commission meeting, but hope you will take our concerns under consideration in your assessment of this development. Thank you for your time and commitment to the City of Chanhassen as your task is not an easy one.

The 100 year rain was mentioned by staff at the meeting last evening which I believe was stated at 6" in 24 hours, this seems to be happening more often than once in a 100 years. There have been many times in the past and will be more in the future when we get more than that in a few days of steady rain. Last fall (Oct. -Nov 2014) we received more than 6" in a few days of constant rain. My property received so much water that I could have had a skating pond over the winter on the area where the water ponds on the north side of my property. This "pond" greatly exceeded the "normal' high water markers placed on my property years ago. How can the currently proposed plat NOT increase drainage onto my and the adjoining properties when especially since the developer states they will have to haul in many tons of earth to do the proposed building of these homes. The current soil is basically clay which causes a lot of runoff so what type of soil will be brought in to reduce this? Staff mentions packing of the soil on the property as a concern. If soil compaction is done in the "usual' way it will be packed to densely and increase more drainage to the south. How will this be monitored or dealt with? Looking at the latest elevations (pages 4 and 6 of commission packet) of lots 1- 6 and possibly 7 the runoff to the south can only be more than present. How will the drainage be monitored to make sure it is not more than what currently drains south? Since there is no direct drain to Lake Lucy from mine or neighbor properties when the water has nowhere to go it backs up onto my property. There have been times in the 20 years I have owned this property that the northern part of my property has been basically inaccessible due to the amount of moisture there. This may be great to drown the wild garlic but also great for the mosquito population. I would like to see a comparison of the existing elevations compared to the proposed elevations for this project and have someone explain to my neighbors and me how the drainage to the south from current proposed preliminary plat will NOT increase due to the change. I will be out of town for the next few days but would like to take this opportunity to invite the council members, staff and whomever to come walk the properties on the south side of Lake Lucy Road after Memorial Day to really SEE the problem that could be caused if drainage into this area is increased at all! Bring your water boots... Sincerely, Betsy (Kathryn) Randall 1571 Lake Lucy Road 952-474-6522 wild-f�, LAKE LUCY ROAD; NEW RESIDENTIAL NEIGHBORHOOD RESPONSES TO STAFF RECOMMENDATIONS to PRELIMINARY PLAT FILING. Planning Commission Meeting, Tuesday, May 17, 2016 We are in full agreement with 76 of SO conditions of approval. Following the section labeled RECOMMENDATIONS on Page 19, there are seven topics, with conditions.

Because we are concerned that these conditions will either adversely impact environmental quality, impose added cost without any real benefit, we would like these conditions to be discussed, and ideally, removed as conditions of approval. Engineering Recommendation number 14 is a significant concern to us for the reasons described below. "Engineering: Condition 14. Retaining walls and entry monument... shall be relocated outside standard perimeter drainage and utility easement boundaries, excepting the retaining wall on Lots 5 and 6." Developer & Consultant Observation: The positions of the retaining walls on lots 5 and 6 serve the some function of assisting drainage, within the "drainage easements", as do the retaining walls on lots 8, 9 and 10. The walls on each one of these lots is critical to the proper drainage and runoff flows, as well as sustaining a suitable area for home construction. Significantly, forcing the walls off of drainage easements, (specifically titled for such use), is an exceptional and unusual requirement that will cause harm. This would impose adverse effects on the functions and values of lots and inhibit drainage, while providing no benefits. We, therefore, request that this Engineering Condition #14 be deleted/ This condition will remain. Per Condition 14, the retaining wall on Lots 5 and 6 may stay inside the easement, but will require an encroachment agreement. That retaining wall must be under an encroachment agreement so that it can be removed when the properties to the west connect to the sanitary sewer near the wall. This is discussed further in the Utility Section of the staff report. For the other retaining walls, requiring them to be constructed outside of drainage and utility easements is not an "exceptional" or "unusual" requirement. The purpose of a perimeter drainage and utility easement is to provide an area for public and private utilities to access the lots and to provide a drainage way between the lots and set back from the building pads. The retaining wall locations proposed would inhibit these purposes. Retaining walls are neither drainage conveyances nor utilities and do not belong in a D&U Easement. The wall on Lot 9 is particularly problematic as maintenance of the wall would require encroachment onto Lot 10. The other three conditions we have concerns regarding are the following: We are being asked to move our entrance monument outside the drainage and utility easement. We have successfully placed entrance monuments within these easements throughout the Metropolitan Area. When they are carefully placed where they won't impede reasonable sight triangles these monuments cause neither transportation nor pedestrian safety problems. And, as long as coordination is done with the relevant utility companies, building, grading and landscape contractors, there is neither any interruption of utility lines nor any drainage problems with this placement. This condition will remain. The placement of the entrance monuments, as proposed, would be within a drainage and utility easement that is specifically dedicated for water and sanitary sewer pipe. When the City performs maintenance or replacement of these pipes, the monument would have to be moved at the expense and likely objection of the Homeowners Association. It is unacceptable to place an entrance monument within this drainage and utility easement, regardless of what the developer has done in other cities in the past. Additionally, the city does not permit monument signage within corner site triangles and would require any signage to be moved out of those site triangles. A. "Environmental Resources Condition: 2. All required plantings must be located on private property outside of public right of way..." Developer & Consultant Observation: Creating a new neighborhood provides an opportunity to introduce the trees that have the greatest visual impact on a city; its boulevard -street trees. Excluding street tree planting from a residential neighborhood's boulevards causes a loss of beauty, and future value gains, at the minor and marginal benefit of potentially, lower maintenance. We understand the value of some limitations on planting with regard to a main collector such as Lake Lucy Road. However, the accepted and typical, well vetted detail has street trees centered between the sidewalk and back of curb, or between the property line and back of curb. That is what our planting plan shows. In these times of tight municipal budgets, and the Emerald Ash Borer, the provision of street -boulevard trees, (conforming to city -approved tree species preferences), is a way to further beautify the city, while also improving the long term values, aesthetics and temperature moderations within new Chanhassen neighborhoods... without direct cost to the City. We, therefore, request that this condition #2 be deleted. The condition will remain. Trees planted on private property near the front property line will still provide a 'boulevard tree' feel to the street but be less exposed to damage from snow plow or sweeping operations as well as out of sight line and utility conflicts. B. "Water Resources: Condition 3: "... achieve a new overall reduction of at least 90% of total suspended solids .... This includes manipulation of the NURP50 Particle Distribution". Developer & Consultant observation: The effect of these changes, (and proposed "manipulations" of generally accepted stormwater software input parameters), would result in multiple stormwater management devices. These would likely result in decreased removal efficiency and increase city maintenance obligations and costs. There is no ordinance standard that requires this requested change. The manipulation of these parameters will not likely advance the total management goals, they simply add redesign costs. We, therefore, request that this condition #3 be deleted. The condition will be modified to read as shown below. "The stormwater management practices shall achieve a net overall reduction of at least 90% for total suspended solids and 60%for total phosphorous using industry accepted removal rates. This includes manipulation of the NURP50 Particle Distribution filtration efficiencies to match accepted literature values." The condition was misstated. The NURP particle distribution remains unchanged. What must change is the efficiency with which the particle removals will occur. The default removal efficiencies assume that 100% of the water is infiltrated to the water table. The proposed systems are designed to have a piped outlet (underdrain and/or surface flow) meaning there will be little to no infiltration. As such, the assumed removal efficiencies are incorrect and are incongruent with accepted literature values and overstate the removal of phosphorous and particulates from the runoff. Code requires that water quality standards of 90%TSS and 60%TP reduction are met. Section 19-144 reads as follows: (3) Newly constructed or modified detention basins shall provide storage volume below the outlet (dead storage) to allow for water quality treatment in accordance with the following, whichever is most restrictive: a. Water quality features meeting the MPCA NPDES construction permit for permanent stormwater management systems; b. Water quality treatment consistent with NURP criteria (90 percent removal of TSS and 60 percent removal of TP for a standard NURP particle size distribution) C. "Water Resources: 18: Efforts shall be made to raise the elevations of Lots 2 through 5 to assure positive flow towards the street and ultimately to the treatment devices. Developer & Consultant Observation: The grading design on the preliminary plat shows a graded pad that is larger than the actual home footprint. In any event, the grading design shows water being conveyed both to the street and, via side yards, to the rear yard and drainage swales. This is a common practice, and positive drainage will be provided. Building Requirement #4 on pg. 19, ensures that final grading plans for each lot and home will be in conformance before building permits are issued. The condition will remain. As presented, the high point is at the front of the building pads on the grading plan. As such, only the front yards will be directed towards the street. The remainder of the lots will discharge to the rear towards the area in question south of Lake Lucy Road. This is a development level issue and not a responsibility to be borne by the builder. In fact, it may be too late at that time to address drainage concerns. If the indicated pad size is the issue then I would suggest altering the pad size to accommodate the anticipated home. The watershed draining to the south must not only be limited to the greatest extent practicable but the assumed drainage areas must match what the proposed grading plan shows.

Yes, Chanhassen Is changing. We are no longer that community of 5,000 as we were 30 years ago. Development on all fronts continue. As your council, it is our job to do what we can to preserve and protect the character and qualities of the city that make it attractive to people that want to experience what we all enjoy. Change is going to happen. We are better stewards of our community when we guide and manage that change, rather than react without vision. I will keep your thoughts in mind as this comes before the council for review. Thank you.

V IKn . This will likely be problematic for future owners of these lots as the ' 1 VN. ck and area for recreational use. At a minimum, the grading=be to provide a 10-foot by 10-foot level area at all exterior egress points. ,`� Newea w#w.T 4e-retW Foil In the proposed plan, Lots 6-9 have been artificially created as walkouts through construction of LC I'Te ^r OF three retaining walls 5-9 feet tall and routing stormwater through the center of their backyard at a 'fyt D~cp shallow slope: approximately 2% at Lot 6, 3% at Lot 7, 2% at Lot 8, and 3-4% at Lot 9. The TO 9 center of this drainage route would be as little as 12 feet behind the building pad of Lot 9. This will likely be problematic for future owners of these lots as there is often an expectation to have a level, dry backyard area for recreational use. Lots 6-9 should be a rambler -style home, as this would fit better with the grading on surroundmg properties and allow the applicant to create more effective drainage for these lots, rather than excavating down and constructing retaining; walls to force a walk -out style home onto the lot. T�� t DesIo� d� s° The front yards of Lots 3, 4 and 5 appear to drain water towards Feuilding pad or would have ( N d Y� a flat driveway grade.

If it is a driveway culvert, the applicant �A shall have it removed or bulkhead and abandoned. Erosion Prevention and Sediment Control The plans shall identify the areas intended for stockpiling materials on site during construction. Retaining Walls The applicant has proposed four retaining walls as part of this subdivision. The wall south of the southeastern wetland is approximately 100 feet long and 4 feet tall. Street A is above this wall, and the southeastern wetland is below the wall. As the sidewalk shall be ✓ moved to the south side of Street A, the retaining wall shall be minimized as much as possible. The retaining wall shall be shifted out of the right-of-way.14"! The retaining wall on the western property line of Lot 8 is approximately 55 feet long and 5 feet tall. The backyard of Lot 8 is below the wall. ? q s � �> Thretaining wall on Lot 9 is approximately 110 feet long and 6 feet tall. The backyard of 0 PC Lo 8 s below the retaining wall. This wall shall be relocated outside the drainage and utility easement. This wall shall be eliminated or reduced size by changjpg the home style of Lots 8 p q� and 9 to ramblers NMz. The retaining wall on the eastern property line of Lot 9 is approximately 80 feet long and 4 feet/ tall. The building pad of Lot 10 is below this wall. Top and bottom wall elevations shall be shown for this retaining wall. This wall shall be relocated outside the drainage and utility easement. The retaining wall at the comer of Lots 5 and 6 is approximately 125 feet long and 9 feet tall. The sideyard of Lot 5 and the backyard of Lot 6 are below this wall. This wall crosses the lot line and thus is on both Lot 5 and 6. Any wall that crosses lot lines shall be owned and�� a f' maintained by a Homeowners Association (HOA). The development plans shall call out the material of the retaining wall. The following materials are prohibited for retaining wall construction: smooth face, poured in place concrete (stamped or 1600 & 1630 Lake Lucy Road Page 3 of 8 patterned is acceptable), masonry, railroad ties and timber. Boulder walls shall not be taller than Ott six feet. RIGHT-O&WAY AND EASEMENTS The survey included all easements and right of way shown on the title search of the property t� dated November 20, 2015 from Stewart Title Guarantee Company. The applicant shall have their survey confirm this with a recent title survey before final plat. The applicant proposes a 60-foot right-of-way over Street A and 60-foot right-of-way radius over the cul-de-sac bubble. The plat maintains the existing, 66-foot right-of-way easements for Lake Lucy Road and Yosemite Avenue. Easements over drainage basins and storm water pipes shall be called out as "Drainage and /" Utility" easements. d� Three retaining walls and two entry monuments are proposed w tin City easements or right of way. These elements shall be relocated outside of the easement. The retaining wall on Lots 5 ✓ and 6 requires an encroac ent agreement. Additional drainage and utility easement shall be granted on Lot 1 to provide 10-feet from the center of the sanitary sewer main. Per § 18-78, staff would like the applicant to examine providing future access for adjacent properties to the west, 1650 and 1670 Lake Lucy Road. Staff recommends an access easement over the north 35 feet of Lot 5 for a future private street to service Lot 5 and the future subdivided properties on existing 1650 and 1670 Lake Lucy Road. STREETS, DRIVEWAYS & SIDEWALK The applicant proposes construction of a public street, Street A. The applicant shall name this street with coordination with the Fire Marshall prior to submittal for final plat review. Street A is proposed to City standards at 31 feet wide and using the Chanhassen Standard Detail typical section. The applicant shall include the horizontal alignment tabulation for Street A in the plans. Access to the subdivision from Street A is located south of the southeastern wetland. This location was chosen after examining three locations: off of Lake Lucy Road, Yosemite Avenue north of the wetland, and Yosemite Avenue south of the wetland. The Lake Lucy Road intersection alternative was eliminated because of sight -distance concerns around the curve on Lake Lucy Road and the desire for access control on Lake Lucy Road, a Major Collector roadway. The Yosemite Avenue access north of the wetland was eliminated due to environmental concerns from running a roadway between the two wetlands across their EOF point and future maintenance concerns due to a long road extension that is surround by wetland instead of servicing properties. 1600 & 1630 Lake Lucy Road Page 4 of 8 The applicant shall appty fora variance to the requirement of 300-foot spacing between local roads per § 18-57. The access location on Yosemite, sou—th o e we ran reusing engineering discretion and the guidelines set forth in the 2030 Comprehensive, the proposed intersection offset seems reasonable as the proposed 12 lot subdivision would generate less traffic than a multiple commercial driveway. The applicant's engineer completed a queuing analysis to confirm that traffic queuing to make a left turn into the proposed development would not affect the function of the Lake Lucy Road & Yosemite Avenue intersection. A street light shall be installed at the intersection of Street A and Yosemite Avenue. 1 Driveways shall be shown on the plan in the final plat submittal. Driveways shall be designed to Y �Y meet all standards in City Code §20-1122. Only one driveway access point is allowed form a single residential lot to the street. To minimise additional stormwater runoff created by long M S'/� driveways required for the "flag" or "neck" lot variance, the applicant shall install a 10-foot IL driveway for the length of the "neck". The sidewalk within the development shall move to the south side of the street. This eliminates the need for pedestrian ramps at the intersection of Street A and Yosemite Avenue. The pedestrian ramp on the northwest corner of the intersection of Lake Lucy Road and Yosemite Avenue shall be replaced per City of Chanhassen Standard Detail Plates. The sidewalk along Yosemite Avenue is very close to the existing utility pole. This conflict will need to be resolved by either moving the sidewalk or the utility pole and shall be shown on the plan set. J l,�rA` V. ( s ON Q.v.N�9 col.= . UTILITIES Sanitary Sewer The applicant proposes an 8" PVC sanitary sewer main to be owned and maintained by the City, Due to the elevation of the adjacent sanitary sewer system on the east side of Yosemite, sanitary sewer for this subdivision does not meet the minimum depth required without insulation. The sanitary sewer pipe shall be insulated wherever it is less than 6 feet deep. The proposed shallow elevation of the sanitary sewer also necessitates Lot 2, 3 and 4 to use a private, in -home grinder system to pump waste to the public sanitary main which is a gravity flow system. The portion of the grinder pump services that lies within the right-of-way shall be gravity -flowing. it The minimum sanitary sewer grade that the City will accept is 0.401/o, therefore setting the ALAW design grade to this minimum is not advisable. The plan must have a design grade that developer and engineer are confident that the construction process will achieve the minimum of 0.40%. Sanitary sewer installed at less than 0.40% shall not be accepted by the City and must be reinstalled at the developer's expense. Staff recommends use of 0.50% minimum design grade. Per § 18-78, the applicant is required to install sanitary sewer main to the western property boundary to provide future extension to the adjacent properties: 1650 and 1670 Lake Lucy Road. It is unlikely they would be able to connect a gravity system to the sanitary main extension and 1600 & 1630 Lake Lucy Road Page 5 of 8 would likely require private grinder pump systems. Staff recommends locating the extension / between Lots 5 and 6, however, the retaining wall would need to be removed at the time of ✓ connection to the adjacent properties at the connecting party's expense. The sanitary sewer/water main crossing on Lot 1 may be in conflict. The applicant's engineer shall verify this when the utility profiles are drafted. SMH 3 shall be moved outside the wheel path to the center of the road or center of the traveled lane. The sanitary services within the cul-de-sac bubble shall be revised to eliminate bends within the right-of-way. .� To reduce future maintenance needs for the City, SMH 1 location shall be adjusted to eliminate the need for SHM 2. e' The utility plan sheet shall be revised to call out the City of Chanhassen as the local authority in Note 13. Water Main The applicant proposes an 8" water main system. The plans shall call out C900 material for the water main pipe. The 90 degree bend shall be replaced with two 45 degree bends to reduce pressure on a single sharp turn of the main. The water main along Yosemite Avenue shall be shifted into the right-of-way. The sanitary sewer/water main crossing on Lot 1 may be in conflict. The applicant's engineer,, -- shall verify this when the utility profiles are drafted. >,S Two additional hydrants shall be installed, one at the intersection of Street A and Yosemite p s Avenue and one at Station 3+00 of Street A. ✓�s �� r+9 TALKING POINTS FOR TUESDAY'S MEETING: The existing togopraphic survey shall show a minimum of 100 feet outside the development boundaries and include the existing first floor elevations of nearby structures. 2.

The water main along Yosemite Avenue shall be shifted into the right-of-way. 50. Two additional hydrants shall be installed, one at the intersection of Street A and Yosemite Avenue and one at Station 3+00 of Street A. The following is a list of my main concerns with the plan as proposed. 1. Runoff rates and volumes cannot be increased to the south. ✓1 Under current conditions the southern and western 40% of the site drains to the south. It is conveyed through a culvert under Lake Lucy Road and discharges into a series of ditches, corrugated metal pipe culverts and wetlands. Water appears to overtop the drive under current conditions at the southern of the two culverts. In order to drain out of the third and final wetland, the water must bounce as much as 3 feet to leave the wetland and reach Lake Lucy. In discussions with Roger Humph he he suggested he would be able to address the watershed area by directing the front of lot 2 throug�lto the street and to the wetlands. It has yet to be seen how this will be accomplished. 2. The stormwater management practices shall achieve an overall reduction of at least 90%for total suspended solids and 60% for total phosphorous using industry accepted removal rates. The modeled design removal efficiencies were considerably greater than the values recognized by the Minnesota Stormwater Manual and other industry standards. This may be due to the limitations of the modeling software. TSS removal efficiency for a filtration device just using a sand media filter should be between 77% and 90%. The modeled removal was 97% and nearly 100%. TP removal efficiencies for the some device type should be between 28% and 56%. This is with additional Wq volume, pretreatment etc. None of which are shown in the design. The model is indicating that between 91% and 96% of the TP will be removed using these devices on this site. Using literature review values, removals for the site in aggregate are more likely between 73% and 84% for TSS and between 27% and 41 % for TP. The applicant must achieve the 90% TSS and 60% TP removal using removal efficiencies recognized as industry standards or otherwise justifiable.

Further, they will discontinue to model the buffer as a best management practice and will instead evaluate the construction of an additional biofiltration basin on lot 10. 3. The applicant shall prepare and submit a Surface Water Pollution Prevention Plan that contains all required elements from Parts III and IV of the NPDES/SDS Construction Permit. This shall be a standalone document. In order to review erosion prevention and sediment control practices comprehensively, a SWPPP needs to be provided. This SWPPP must be exclusive of the plan set so that it can be reviewed on its own merits. The city has modified a SWPPP review checklist developed by the PCA so that it is more specific to Chanhassen. This checklist can be made available upon request. 4. It will be required that six inches of topsoil be placed on all disturbed areas to be vegetated V/ throughout the subject property. This shall be reflected in the grading plan, erosion plan and SWPPP. 5. The upland area between the two wetlands shall be graded to allow for a safe and stable overflow from the north wetland to the east wetland. In order for the routing to function properly, a stabilized overflow swale will be necessary to route runoff to the east. This area shall be protected from soil losses to the wetland through erosion and shall be stabilized within 48 hours of completion of earth moving activities. The developer and the contractor shall submit a completed Landowner Statement and Contractor Responsibility form to the City. 6. Any disturbance of the buffer areas shall be restored with native vegetation appropriate to thc-� area and the plans shall note this and the seed mix to be used. All stormwater practices shall be place into a drainage and utility easement if not included in an outlot. An outlot will always be the preferred option. 8. An operations and maintenance manual shall be developed for the practices to be employed and submitted to the City. This document shall clearly indicate who is responsible for what tasks, schedule of anticipated maintenance milestones, detailed grading and planting plans including any appurtenant infrastructure. Staff is concerned about the long term viability of these biofiltration basins given their proximity to proposed house pads and potentially problematic access. The Zo I n ed to prepare an operations and maintenance manual for the features includina inspection schedule. The applicant will need to form a Home Owners' Association to assume ownership and responsibility for the maintenance of any landscaping the HOA may wish to have. The city will assume responsibility for the underdrains, refreshing the iron filings and any storm sewer conveyance into these features. The development contract shall reflect this and a drainage and utility easement shall be recorded over all features. 9. The plans and the O&M shall clearly indicated how reasonable and access will be granted to each practice and assured throughout the life of the practice. �oS pry •> f� Features that are not reasonably accessible may not be accepted by the city.—W 10. The development contract shall include language indicating that the Homeowners' Association shall be responsible for any landscaping work associated with the biofiltration features and the city shall maintain the associated infrastructure including the underdrain, the filtration media and the storm sewer conveyance system. 11. The wet detention pond shall be no larger in surface area or depth than is necessary. If the intent is to route the bulk of the water to the north there should be little need for a pond of this size. The depth of the pond lends to less desirable lots as the homes will walk out onto a 3:1 side slope down to the pond. 12. The wet detention pond shall be designed to have an emergency overflow skimmer outlet structure. Lake Lucy Road shall not be used as the emergency overflow and the existing RCP flared end section is cracked. 13. A detailed plan of the filtration basins, consistent with the MN Stormwater Manual shall be submitted with the final plat submittal for review and approval by city staff. It shall include, at a minimum, a plan view, a profile view, all necessary elevations, any in situ soil preparation, methodologies to be employed to protect from construction traffic, soil filter media V specifications, any plantings and any appurtenant work to be done. These plans shall reflect the MN Stormwater Manual recommendations and requirements for filtration basins. These plans shall be adequate for construction to engineering specifications without confusion. It has been the city's experience that the level of detail necessary for proper construction is lacking from these plan types. Cam' 14. Underdrains and drain tile shall have tracer wire and cleanouts and a butterfly valve shall be installed on the underdrain so that the outflow can be adjusted to achieve maximum infiltration. Currently the only justification for the absence of any infiltration is the geotechnical borings which were performed with the construction of house pads, roads, etc in mind and do not Se. necessarily reflect the potential for infiltration throughout the site. Gulliver, et al showed that up to 1 soil boring or permeameter test may be needed per 1,000 SF. 7 o� 144 15. Pretreatment shall be required for all filtration basins receiving piped discharge. 7 16. The biofiltration devices shall be designed and constructed as infiltration/filtration/recharge facilities unless it can be shown that a limitation such as less than 3 feet to ground water or bedrock is an existing condition. 17. The elevations of Lots 2 through 5 shall be raised to assure positive flow towards the street and ultimately to the treatment devices and to minimize flow to the south such that there is no increase in volume or rates leaving the site under Lake Lucy Road. It does not appear that the proposed drainage boundaries for P4, P5 and P5 are reflected in the grading plan. There appears to be poor drainage in the front yards and a steeper hydraulic gradient towards the back yards of these lots in this area. This may be further complicated by the trail moving to the south side of the cul de sac. 17 18. There is positive drainage towards the houses on Lots 7, 8 and 9. This is not an acceptable condition. 19. According to the grading plan, a low spot will be created on the southern lot line of lot 6 7 adjacent to the retaining wall. This is an unacceptable condition. . 20. Storm Water Utility Connection charges due at the final plat are estimated to be $58,880.00. Many of these items have been discussed with the consulting engineers and they are working to resolve those issues. However, in the absence of a plan set showing the resolution to be practical, all comments �— remaingermane at the time. This concludes my review. Thank you. &W�� Grading & Drainage The existing togopraphic survey shall show a minimum of 100 feet outside the development boundaries and include the existing first floor elevations of nearby structures. Storm sewer and treatment areas shall be shown on the grading plan. b Based on the building pads shown, the hardcover area generating stormwater runoff on Lots 1-4 and 6-10 exceed the 25% maximum without taking the driveways into account. Many greatly Vf-., exceed 25% and go as high as 37�ardcover. The applicant shall show building styles and driveways to confirm their ability to meet the 25% maximum hardcover requirement. r� The lots shall be graded to drain away from proposed building locations. Spot elevations shall be shown on the plans to verify that water will drain away from buildings at the following locations: Lot 6 backyard, Lot 7 backyard, the east side of Lot 1, the front yard of Lot 2. Lot 9 appears to drain toward the building on the north and west side. Lot 9 grading shall be revised to route water away from the building pad. -- Lots 2, 3 4 and 5 on the southern half of the property show little or no level back yard area. For example, Lot 3 has a 3-foot level area, then a 3:1 slope (the maximum allowed within a subdivision) goes down 10 feet in elevation to a 12-foot level area around the stormwater pond. This will likely be problematic for future owners of these lots as there is often an expectation to have a level backyard area for recreational use. At a minimum, the grading plan shall be revised to provide a 10-foot by 10-foot level area at all exterior egress points. In the proposed plan, Lots 6-9 have been artificially created as walkouts through construction of three retaining walls 5-9 feet tall and routing stormwater through the center of their backyard at a shallow slope: approximately 2% at Lot 6, 3% at Lot 7, 2% at Lot 8, and 34% at Lot 9. The center of this drainage route would be as little as 12 feet behind the building pad of Lot 9. This will likely be problematic for future owners of these lots as there is often an expectation to have a level, dry backyard area for recreational use. Lots 6-9 should be a rambler -style home, as this would fit better with the grading on surrounding properties and allow the applicant to create more effective drainage for these lots, rather than excavating down and constructing retaining walls to force a walk -out style home onto the lot. The front yards of Lots 3, 4 and 5 appear to drain water towards the building pad or would have a flat driveway grade. The front yard grading plan shall be revised to allow a minimum of 0.5% slope on the driveways and to drain away from the proposed building pad. The backyard drainage on Lot 12 shall be revised to a minimum of 2%. Draintile is required for all lots where stormwater runoff will flow from the back to the front of the property. Draintile shall be shown on the plans for Lots 6, 7, 8, and 9. The plan shall show EOF locations and elevation for all basins and wetlands on site. All EOF shall be at least 1 foot below the lowest opening of adjacent homes. 1600 & 1630 Lake Lucy Road Page 2 of 8 The low point near the Lots 5 and 6 retaining wall and the low point on the cul-de-sac bubble shall be incorporated into the storm sewer system to drain. To minimize additional stormwater runoff created by long driveways required for the "flag" or "neck" lot variance, the applicant shall install a 10-foot driveway for the length of the "neck". The applicant shall identify the discharge point of the culvert shown on the existing topography near the existing driveway of 1600 Lake Lucy Road. If it is a driveway culvert, the applicant shall have it removed or bulkhead and abandoned. Erosion Prevention and Sediment Control The plans shall identify the areas intended for stockpiling materials on site during construction. Retaining Walls The applicant has proposed four retaining walls as part of this subdivision. The wall south of the southeastern wetland is approximately 100 feet long and 4 feet tall. Street A is above this wall, and the southeastern wetland is below the wall. As the sidewalk shall be moved to the south side of Street A, the retaining wall shall be minimized as much as possible. The retaining wall shall be shifted out of the right-of-way. The retaining wall on the western property line of Lot 8 is approximately 55 feet long and 5 feet tall. The backyard of Lot 8 is below the wall. The north retaining wall on Lot 9 is approximately 110 feet long and 6 feet tall. The backyard of Lot 8 is below the retaining wall. This wall shall be relocated outside the drainage and utility easement. This wall shall be eliminated or reduced in size by changing the home style of Lots 8 and 9 to ramblers The retaining wall on the eastern property line of Lot 9 is approximately 80 feet long and 4 feet tall. The building pad of Lot 10 is below this wall. Top and bottom wall elevations shall be shown for this retaining wall. This wall shall be relocated outside the drainage and utility easement. The retaining wall at the comer of Lots 5 and 6 is approximately 125 feet long and 9 feet tall. The sideyard of Lot 5 and the backyard of Lot 6 are below this wall. This wall crosses the lot line and thus is on both Lot 5 and 6. Any wall that crosses lot lines shall be owned and maintained by a Homeowners Association (HOA). The development plans shall call out the material of the retaining wall. The following materials are prohibited for retaining wall construction: smooth face, poured in place concrete (stamped or 1600 & 1630 Lake Lucy Road Page 3 of 8 patterned is acceptable), masonry, railroad ties and timber. Boulder walls shall not be taller than six feet. RIGHT-OF-WAY AND EASEMENTS The survey included all easements and right of way shown on the title search of the property dated November 20, 2015 from Stewart Title Guarantee Company. The applicant shall have their survey confirm this with a recent title survey before final plat. The applicant proposes a 60-foot right-of-way over Street A and 60-foot right-of-way radius over the cul-de-sac bubble. The plat maintains the existing, 66-foot right-of-way easements for Lake Lucy Road and Yosemite Avenue. Easements over drainage basins and storm water pipes shall be called out as "Drainage and Utility" easements. Three retaining walls and two entry monuments are proposed within City easements or right of way. These elements shall be relocated outside of the easement. The retaining wall on Lots 5 and 6 requires an encroachment agreement. Additional drainage and utility easement shall be granted on Lot 1 to provide 10-feet from the center of the sanitary sewer main. Per § 18-78, staff would like the applicant to examine providing future access for adjacent properties to the west, 1650 and 1670 Lake Lucy Road. Staff recommends an access easement over the north 35 feet of Lot 5 for a future private street to service Lot 5 and the future subdivided properties on existing 1650 and 1670 Lake Lucy Road. STREETS, DRIVEWAYS & SIDEWALK The applicant proposes construction of a public street, Street A. The applicant shall name this street with coordination with the Fire Marshall prior to submittal for final plat review. Street A is proposed to City standards at 31 feet wide and using the Chanhassen Standard Detail typical section. The applicant shall include the horizontal alignment tabulation for Street A in the plans. Access to the subdivision from Street A is located south of the southeastern wetland. This location was chosen after examining three locations: off of Lake Lucy Road, Yosemite Avenue north of the wetland, and Yosemite Avenue south of the wetland. The Lake Lucy Road intersection alternative was eliminated because of sight -distance concerns around the curve on Lake Lucy Road and the desire for access control on Lake Lucy Road, a Major Collector roadway. The Yosemite Avenue access north of the wetland was eliminated due to environmental concerns from running a roadway between the two wetlands across their EOF point and future maintenance concerns due to a long road extension that is surround by wetland instead of servicing properties. 1600 & 1630 Lake Lucy Road Page 4 of 8 The applicant shall apply for a variance to the requirement of 300-foot spacing between local roads per § 18-57. The access location on Yosemite, south of the wetland reviewed using engineering discretion and the guidelines set forth in the 2030 Comprehensive, the proposed intersection offset seems reasonable as the proposed 12 lot subdivision would generate less traffic than a multiple commercial driveway. The applicant's engineer completed a queuing analysis to confirm that traffic queuing to make a left tum into the proposed development would not affect the function of the Lake Lucy Road & Yosemite Avenue intersection. A street light shall be installed at the intersection of Street A and Yosemite Avenue. Driveways shall be shown on the plan in the final plat submittal. Driveways shall be designed to meet all standards in City Code §20-1122. Only one driveway access point is allowed form a single residential lot to the street. To minimize additional stormwater runoff created by long driveways required for the "flag" or "neck" lot variance, the applicant shall install a 10-foot driveway for the length of the `heck". The sidewalk within the development shall move to the south side of the street. This eliminates the need for pedestrian ramps at the intersection of Street A and Yosemite Avenue. The pedestrian ramp on the northwest comer of the intersection of Lake Lucy Road and Yosemite Avenue shall be replaced per City of Chanhassen Standard Detail Plates. The sidewalk along Yosemite Avenue is very close to the existing utility pole. This conflict will need to be resolved by either moving the sidewalk or the utility pole and shall be shown on the plan set. UTILITIES Sanitary Sewer The applicant proposes an 8" PVC sanitary sewer main to be owned and maintained by the City, Due to the elevation of the adjacent sanitary sewer system on the east side of Yosemite, sanitary sewer for this subdivision does not meet the minimum depth required without insulation. The sanitary sewer pipe shall be insulated wherever it is less than 6 feet deep. The proposed shallow elevation of the sanitary sewer also necessitates Lot 2, 3 and 4 to use a private, in -home grinder system to pump waste to the public sanitary main which is a gravity flow system. The portion of the grinder pump services that lies within the right-of-way shall be gravity -flowing. The minimum sanitary sewer grade that the City will accept is 0.40%, therefore setting the design grade to this minimum is not advisable. The plan must have a design grade that developer and engineer are confident that the construction process will achieve the minimum of 0.40%. Sanitary sewer installed at less than 0.40% shall not be accepted by the City and must be reinstalled at the developer's expense. Staff recommends use of 0.50% minimum design grade. Per § 18-78, the applicant is required to install sanitary sewer main to the western property boundary to provide future extension to the adjacent properties: 1650 and 1670 Lake Lucy Road. It is unlikely they would be able to connect a gravity system to the sanitary main extension and The modeled design removal efficiencies were considerably greater than the values recognized by the Minnesota Stormwater Manual and other industry standards. This may be due to the limitations of the modeling software. TSS removal efficiency for a filtration device just using a sand media filter should be between 77% and 90%. The modeled removal was 97% and nearly 100%. TP removal efficiencies for the same device type should be between 28% and 5696. This is with additional WQ volume, pretreatment, etc. None of which are shown in the design. The model is indicating that between 91% and 96% of the TP will be removed using these devices on this site. Using literature review values, removals for the site in aggregate are more likely between 73% and 84% for TSS and between 27% and 41 % for TP. The applicant must achieve the 90% TSS and 60% TP removal using removal efficiencies recognized as industry standards or otherwise justifiable.

Further, they will discontinue to model the buffer as a best management practice and will instead evaluate the construction of an additional biofiltration basin on lot 10. 3. The applicant shall prepare and submit a Surface Water Pollution Prevention Plan that contains all required elements from Parts III and IV of the NPDES/SDS Construction Permit. This shall be a standalone document. In order to review erosion prevention and sediment control practices comprehensively, a SWPPP needs to be provided. This SWPPP must be exclusive of the plan set so that it can be reviewed on its own merits. The city has modified a SWPPP review checklist developed by the PCA so that it is more specific to Chanhassen. This checklist can be made available upon request. 4. It will be required that six inches of topsoil be placed on all disturbed areas to be vegetated throughout the subject property. This shall be reflected in the grading plan, erosion plan and SWPPP. 5. The upland area between the two wetlands shall be graded to allow for a safe and stable overflow from the north wetland to the east wetland. In order for the routing to function properly, a stabilized overflow Swale will be necessary to route runoff to the east. This area shall be protected from soil losses to the wetland through erosion and shall be stabilized within 48 hours of completion of earth moving activities. The developer and the contractor shall submit a completed Landowner Statement and Contractor Responsibility form to the City. 6. Any disturbance of the buffer areas shall be restored with native vegetation appropriate to the area and the plans shall note this and the seed mix to be used. 7. All stormwater practices shall be place into a drainage and utility easement if not included in an outlot. An outlot will always be the preferred option. 8. An operations and maintenance manual shall be developed for the practices to be employed and submitted to the City. This document shall clearly indicate who is responsible for what tasks, schedule of anticipated maintenance milestones, detailed grading and planting plans including any appurtenant infrastructure. Staff is concerned about the long term viability of these biofiltration basins given their proximity to proposed house pads and potentially problematic access. The applicant will need to prepare an operations and maintenance manual for the features including inspection schedule. The applicant will need to form a Home Owners' Association to assume ownership and responsibility for the maintenance of any landscaping the HOA may wish to have. The city will assume responsibility for the underdrains, refreshing the iron filings and any storm sewer conveyance into these features. The development contract shall reflect this and a drainage and utility easement shall be recorded over all features. 9. The plans and the O&M shall clearly indicated how reasonable and access will be granted to each practice and assured throughout the life of the practice. Features that are not reasonably accessible may not be accepted by the city. 10. The development contract shall include language indicating that the Homeowners' Association shall be responsible for any landscaping work associated with the biofiltration features and the city shall maintain the associated infrastructure including the underdrain, the filtration media and the storm sewer conveyance system. 11. The wet detention pond shall be no larger in surface area or depth than is necessary. If the intent is to route the bulk of the water to the north there should be little need for a pond of this size.

The wet detention pond shall be designed to have an emergency overflow skimmer outlet structure. Lake Lucy Road shall not be used as the emergency overflow and the existing RCP flared end section is cracked. 13. A detailed plan of the filtration basins, consistent with the MN Stormwater Manual shall be submitted with the final plat submittal for review and approval by city staff. It shall include, at a minimum, a plan view, a profile view, all necessary elevations, any in situ soil preparation, methodologies to be employed to protect from construction traffic, soil filter media specifications, any plantings and any appurtenant work to be done. These plans shall reflect the MN Stormwater Manual recommendations and requirements for filtration basins. These plans shall be adequate for construction to engineering specifications without confusion. It has been the city's experience that the level of detail necessary for proper construction is lacking from these plan types. 14. Underdrains and drain tile shall have tracer wire and cleanouts and a butterfly valve shall be installed on the underdrain so that the outflow can be adjusted to achieve maximum infiltration. Currently the only justification for the absence of any infiltration is the geotechnicol borings which were performed with the construction of house pads, roads, etc in mind and do not necessarily reflect the potential for infiltration throughout the site. Gulliver, et al showed that up to 1 soil boring or permeameter test may be needed per 1,000 SF. 15. Pretreatment shall be required for all filtration basins receiving piped discharge. 16. The biofiltration devices shall be designed and constructed as infiltration/filtration/recharge facilities unless it can be shown that a limitation such as less than 3 feet to ground water or bedrock is an existing condition. 17. The elevations of Lots 2 through 5 shall be raised to assure positive flow towards the street and ultimately to the treatment devices and to minimize flow to the south such that there is no increase in volume or rates leaving the site under Lake Lucy Road. It does not appear that the proposed drainage boundaries for P4, PS and P6 are reflected in the grading plan. There appears to be poor drainage in the front yards and a steeper hydraulic gradient towards the backyards of these lots in this area. This maybe further complicated by the trail moving to the south side of the cul de sac. 18. There is positive drainage towards the houses on Lots 7, 8 and 9. This is not an acceptable condition. 19. According to the grading plan, a low spot will be created on the southern lot line of lot 6 adjacent to the retaining wall. This is an unacceptable condition. 20. Storm Water Utility Connection charges due at the final plat are estimated to be $58,880.00. Many of these items have been discussed with the consulting engineers and they are working to resolve those issues. However, in the absence of a plan set showing the resolution to be practical, all comments remain germane at the time. This concludes my review. Thank you. The following is a list of my main concerns with the plan as proposed. 1. Runoff rates and volumes cannot be increased to the south. Under current conditions the southern and western 40% of the site drains to the south. It is conveyed through a culvert under Lake Lucy Road and discharges into a series of ditches, corrugated metal pipe culverts and wetlands. Water appears to overtop the drive under current conditions at the southern of the two culverts. In order to drain out of the third and final wetland, the water must bounce as much as 3 feet to leave the wetland and reach Lake Lucy. Y � 1 C ' il1�' � • � / �ry� In discussions with Roger Humphries, he suggested he would be able to address the watershed area by directing the front of lots 2 through 7 to the street and to the wetlands. It has yet to be seen how this will be accomplished. 2. The stormwater management practices shall achieve an overall reduction of at least 90% for total suspended solids and 60%for total phosphorous using industry accepted removal rates. 1600 & 1630 Lake Lucy Road Page 5 of 8 would likely require private grinder pump systems. Staff recommends locating the extension between Lots 5 and 6, however, the retaining wall would need to be removed at the time of connection to the adjacent properties at the connecting parry's expense. The sanitary sewer/water main crossing on Lot 1 may be in conflict. The applicant's engineer shall verify this when the utility profiles are drafted. SMH 3 shall be moved outside the wheel path to the center of the road or center of the traveled lane. The sanitary services within the cul-de-sac bubble shall be revised to eliminate bends within the right-of-way. To reduce future maintenance needs for the City, SMH 1 location shall be adjusted to eliminate the need for SHM 2. The utility plan sheet shall be revised to call out the City of Chanhassen as the local authority in Note 13. Water Main The applicant proposes an 8" water main system. The plans shall call out C900 material for the water main pipe. The 90 degree bend shall be replaced with two 45 degree bends to reduce pressure on a single sharp turn of the main. The water main along Yosemite Avenue shall be shifted into the right-of-way. The sanitary sewer/water main crossing on Lot 1 may be in conflict. The applicant's engineer shall verify this when the utility profiles are drafted. Two additional hydrants shall be installed, one at the intersection of Street A and Yosemite Avenue and one at Station 3+00 of Street A. TALKING POINTS FOR TUESDAY'S MEETING: / 1.

Additional drainage and utility easement shall be granted on Lot 1 to provide 10-feet from the center of the sanitary sewer main. 28. Per § 18-78, staff would like the applicant to examine providing future access for adjacent properties to the west, 1650 and 1670 Lake Lucy Road. Staff recommends an access easement over the north 35 feet of Lot 5 for a future private street to service Lot 5 and the future subdivided properties on existing 1650 and 1670 Lake Lucy Road. 29. The applicant shall name this Street A with coordination with the Fire Marshall prior to submittal for final plat review. 30.

CITY OF CHANHASSEN RECEIVED APR U "1 2016 CHANHASSEN PANNING OEPT DRAINAGE REPORT Apnl 1, 2016 A drainage analysis was completed for the proposed Lake Lucy Road project located northwest of the intersection of Lake Lucy Road and Yosemite Ave in Chanhassen, Minnesota. The proposed development will included 12 single family home lots with a new roadway and utilities. The following is a summary of the stormwater analysis completed for this development. Summary of Site Drainage Existing Conditions Under the existing conditions, the 9.0 arce site, which has a total drainage area of approximately 13.5 acres, is divided by a natural ridge that cuts the site approximately in half. This divide is also the hydrologic boundary between Minnehaha Creek Watershed District (MCWD) to the north and Riley Purgatory Bluff Creek Watershed District (RPBCWD) to the south. The north half of the site drains to two existing wetlands. These wetlands are connected by an overland spillway. Approximately 4 acres from off -site land to the north drains to the north wetland. The south half of the site drains to an existing culvert that flows to the south across Lake Lucy Road. The site is primarily wooded with 3 single family homes located on the southern side of the site. Proposed Conditions Proposed conditions will include the construction of 12 single family homes, a new roadway, and new utilities. The general drainage patterns will remain with the northern portion of the site draining to the two wetlands and the southern portion of the site draining to a proposed wet detention pond to the south. Runoff from the roadway will be treated by two filtration basins. The majority of pervious surfaces of the site will be turf, with the northwest corner being kept as woods. An emergency outflow pipe will be placed at the south end of Wetland East to provide additional outflow capacity during storm events that exceed the 100-yr, 24-hr event. Design Criteria Criteria and assumptions made for this analysis: • Peak runoff rates not to increase for the 2-, 10-, and 100-yr, 24-hr storm events. • Rainfall depths assuming TP-40 were used for this analysis with Type II rainfall distribution. Rainfall Event Rainfall Depth (in) 2-yr 2.8 10-yr 4.2 100-yr 6.0 • Minimum time of concentration was assumed to be 6 minutes. • Water quality requirement must meet NURP criteria (90%Total Suspended Solids (TSS) removal and 60%Total Phosphorus (TP) removal) ® Stantec OP v:\1938\active\193903412\de gn\stormwater\1604-0i sub ffl.1\193BW412 drainage-memo-160401.do x t DRAINAGE REPORT April 1, 2016 • Infiltration: Due to the presence of Hydrologic Soil Group (HSG) Type D soils, infiltration is not recommended for this site. • Wetlands: Meet the wetland requirements for bounce and inundation period for Manage 1 and Manage 2 wetland classifications. Peak Rate Control The following table summarizes the peak flow rates for each drainage area for the 2, 10, and 100-yr, 24-hr storm events under existing and proposed conditions. Based on the analysis the proposed stormwater management meets the City's requirements for peak rate control. Refer to the attached drainage area map and HydroCAD output information for further details. Rate Control Summary 2-year I 10-year 100-year Condition (cfs) (cfs) :is) To South 5.4 9.7 13.5 Existing Conditions I To West j 0.4 0.8 1.4 To South 3.0 6.7 9-7 Proposed Conditions I To West 0.0 0.0 0.0 Volume Control The soils on site consist of primarily sandy clays and clayey sands. These soils don't provide good infiltration rates: therefore, infiltration is considered an inappropriate form of stormwater management. In place of infiltration features, filtration features will be used to treat stormwater prior to discharging offsite. Water Quality Since infiltration is not feasible on the site, NURP water quality standards (90%TSS removal and 60% TP removal) were met. To achieve these standards, filtration basins and natural turf buffers were used. The software modeling program P8 was used to perform the necessary water quality calculations. NURP standards were achieved for each outfall location; wetland north, wetland east, and the pond outlet. A separate analysis was conducted for each outfall. Drainage areas for each outfall included some portions from offsite areas and undisturbed on -site areas. These areas were included in the analysis, but sediment loadings were removed to appropriately analyze the land disturbance drainage. Below is a summary of each outfall.

Onsite drainage area includes roadway, housing lots, and turf surfaces. The roadway and a portion of the lots will be routed to a 1.5-ft deep filtration basin with a draintile underdrain for treatment prior to discharging to the wetland. The remainder of the Wetland North drainage area flows overland (or turf buffer areas) prior to discharging to the wetland. Wetland East The Wetland East receives flow from a small area of on-site/disturbed area are form the west with the majority of the drainage area being from offsite/undisturbed areas. The on -site drainage area primarily includes a portion of residential lot area and a small amount of new sidewalk. The primary stormwater treatment features will consist of a turf buffer area and a small 1-ft high filtration berm that runs along the perimeter of the wetland. South The South outfall receive flow from southern portion of the site include the east portion of the proposed roadway. The runoff from the roadway is routed to a 1.0-ft deep filtration basin with a draintile underdrain for pretreatment prior to discharging into the wet detention pond. The wet detention pond includes a 5-ft deep permanent pool to provide water quality treatment prior to discharging off site. Below is a summary of the TSS and TP removal efficiencies. Based on the analysis the proposed stormwater management meets the City's requirements for water quality treatment. More information can be found in the attached P8 output data. Water Quality Summary outfall TSS Removal Efficiency (%) TP Removal Efficiency (%) Wetland North 90.3 62.0 Wetland East 94.3 76.3 South 95.9 76.8 Wetlands The general understanding of how the wetlands function under existing conditions is that Wetland East overflows into Wetland North through the natural spillway at an elevation of 1006.6. and then Wetland North discharges at an unknown rate to the east through an outlet pipe at the northeast corner of Wetland North. The functionality of this outlet pipe is currently unknown ® Stantec apv:\1938\active\193803412\design\stormwater\1604-01 submitta1\193803412 drainage_ memo_160401.docx DRAINAGE REPORT April I, 2016 and therefore is not included in the HydroCAD modeling. The two wetlands onsite are classified as Manage 1 (Wetland East) and Manage 2 (Wetland North). These types of wetlands have specific bounce and inundation period required based on the Recommended Wetland Management Classification System that accompanies the Minnesota Routine Assessment Method (MnRAM) Evaluating Wetland Function that are summarized in the table below. Wetland Permitted Inundation Inundation Management Bounce for 10-yr Period for 1-year Period for 10-yr Runout Control Classification Event & 2-year Event Event Elevation Manage 1 Existing + 0.5 it Existing + 1 day Existing + 7 days No Change 0 to 1.0 ft aboveexisting Manage 2 Existing + 1.0 itExisting + 2 days Existing + 14 days runout An inundation period analysis would not be accurate due to the unknown nature of the existing outlet pipe, therefore, bounce and runout control elevation criteria are the only requirement that were analyzed. The outlet elevation of Wetland East cannot be lowered; therefore an emergency outlet pipe was place at an elevation of 1006.7 which is above the existing overland spillway elevation. This emergency outlet will help alleviate flooding potential of the wetland areas during larger storm events (e.g. greater than 100-yr event). The table below summarizes the wetland analysis.

I have been fortunate to have been involved in the development of several important projects in Chanhassen throughout my career, including Near Mountain, Longacres, Springfield and the Highlands at Lake St. Joe. Each of these projects presented their own distinct opportunities and challenges and all of them were improved as a result of the guidance and assistance of the City's excellent staff. This project continued that tradition. This proposal is for the development of an infill site and like many others this property has presented a number of challenges. I am grateful to the staff for working closely with our team as we sought design solutions to respond to the many development constraints that are present on this property. Candidly, I had hoped to find a plan that would yield more lots, but in the end I am confident that we have created the plan that best fits this site and is the best compliment to its surroundings. We look forward to hosting a neighborhood gathering at the Chanhassen Recreation Center on April 7 and to the opportunity to present our project to the Planning Commission and City Council. I am confident that you will agree with me that our proposal will result in the development of another great Chanhassen neighborhood. It is a pleasure to be back working in Chanhassen. Sincerely, Terry Forbord Yosemite Holdings LLC Stantec 2 LAKE LUCY ROAD, YOSEMITES HOLDINGS, LLC RESIDENTIAL NEIGHBORHOOD SUMMARY OF REZONING, SUBDIVISION AND VARIANCE APPLICATION Yosemite Holdings LLC respectfully requests approval for a rezoning, subdivision approval and three variances for flag lots to authorize the development of a 12 lot subdivision located in the NW Quadrant of Lake Lucy Road and Yosemite Avenue in the City of Chanhassen. We have reviewed the application checklist, submitted all of the required items and the relevant fees and believe our application is complete to initiate the City review and approval process. COMPREHENSIVE PLAN CONSISTENCY The Subject property is guided Low Density Residential In the Chanhassen Comprehensive Plan which is consistent with the rezoning to RSF District zoning that we are seeking. The Comprehensive Plan supports the policy of zoning the property RR Rural residential until municipal utilities are available to support development at densities consistent with the City's 15,000 sq. ft. minimum lot size. The City has fulfilled its plans to provide municipal sanitary sewer and water to serve this property and the developer is seeking the rezoning required to extend these utilities and develop the land as anticipated in the Comprehensive Plan. REZONING FROM RR RURAL RESIDENTIAL TO RSF SINGLE FAMILY RESIDENTIAL DISTRICT With the availability of municipal water and sanitary sewer service to the property the existing property owners have elected to sell their property. The rezoning from RR District to RSF District is fully consistent with the Comprehensive Plan now that the City has constructed the utility services to the area to improve this property. SUBDIVISION APPROVAL The City of Chanhassen's minimum lot size in the RSF District is 15,000 sq. Ft. The Subject Property contains a total of 390,563 sq. ft. (8.96 acres). As the development summary on Figure C1.01 shows, this gross density is reduced by 38,687 sq. ft. of existing street right-of-way from Lake Lucy Road and Yosemite Avenue and an additional 41,629 sq. ft. for the street to serve this subdivision. There is also 32,984 sq. ft. of delineated wetland area within the property boundaries and the City ordinance requires an additional 17,404 sq. ft. of wetland buffer area surrounding the wetland boundaries. The combination of all of these factors reduces the total net acreage of the property to 259,895 sq. ft. (5.96 acres). Pursuant to the Comprehensive Plan, this area is sufficient to support just over seventeen (17), 15,000 sq. ft. lots. However, the shape of the property, configuration of the wetlands, the site topography and access limitations make it impossible to utilize the property to this level of efficiency. These factors combine to yield a total of only 12 single family lots. All of these lots exceed the City's 15,000 sq. ft. minimum lot size and all of them are configured to accommodate a minimum of 70 ft. wide pad sizes. Many of the pads are 80 ft. wide and several lots exceed 20,000 sq. ft. in area and are fully consistent with the general image and character of Chanhassen's low density single family residential district. VARIANCES REQUEST JUSTIFICATION The factors listed above all justify the approval of three simple variances that will allow the property to be put to a reasonable use without jeopardizing the essential character of Chanhassen's single family neighborhoods. Each of these factors is also graphically illustrated on exhibits that are attached to this narrative. Again, all of the proposed lots exceed the lot area requirements and all will accommodate large house pads. The difficult shape, tight dimensions along the western boundary, access limitations and the shape of the wetlands and buffers all combine to necessitate three flag lots. These proposed flag lots are lots 5, 8 and 9. All of them contain well over the minimum lot sizes and all of them have generous building pads. It is the dimension of the north western site boundary that makes it impossible to meet the letter of the code for these highly desirable park -view lots. The following information describes all of the ways in which the Subject Property complies with the conditions and criteria needed to justify the requested flag lot variances. The following is taken directly from Sec. 18-22 —Variances in the Chanhassen Code. Sec. 18-22. - Variances. The City council may grant a variance from the regulations contained in this chapter as part of the plat approval process following a finding that all of the following conditions exist: (1)The hardship is not a mere inconvenience; (2)The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land; (3)The condition or conditions upon which the request is based are unique and not generally applicable to other property; (4)The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of this chapter, the zoning ordinance and comprehensive plan. The property has an irregular shape due to surrounding subdivision patterns. It contains two irregularly shaped delineated wetlands that require 50 ft. and 55 ft. of wetland buffer and setbacks. The site also has access limitations and constraints along both Lake Lucy Road and Yosemite Avenue, including a spacing requirement from Lake Lucy Road along Yosemite Avenue to accommodate safe traffic queuing. Required setbacks around the perimeter of the property (rear yard and some side yard setbacks) further complicate the challenges associated with the shape of the parcel. Adding to the challenge of putting the property to a reasonable use is its topography and the limited depth of the sanitary sewer pipe that will serve the development. In our presentation before the Planning Commission we will provide a more complete description of the numerous site plan alternatives that have been explored and reviewed with City staff. There are two exhibits that illustrate existing, limiting site conditions; (pages 4 & 5). An added four exhibits included in this submission packet that are labelled Sanitary Sewer Serviceability Study (pages 6 —10). Each of these illustrate development constraints due to the project topography in relation to the elevation of the ® Stantec 3 sanitary sewer pipe that will serve the property. These exhibits each describe different aspects of this constraint as it relates to different development concepts, but the essential point is that a significant portion of the property does not offer basement elevations that are high enough to drain by gravity into the sanitary sewer system. This fact, when coupled with the other constraints listed above, has caused the Development Team to explore numerous design alternatives. Each of these have been reviewed and discussed with City staff, including numerous options for site grading, sewer lift stations, grinder pumps and other forms of pressurized sewer systems before the proposed plan was selected. The relationship between the physical conditions of this property and the existing sanitary sewer elevation is a practical difficulty that is unique to this property. A review of the great lengths the Development Team and staff have gone to find an acceptable solution proves that these sewer service constraints present more than mere inconvenience. The result of granting the requested variances results in a subdivision that meets the purpose and intent of Sec.18-22 Variances and the comprehensive plan and zoning ordinance. The consequences of the hardships and practical difficulties facing the development of this parcel are directly related to its distinct physical surroundings, shape, topography and natural conditions; and they present challenges that go well beyond mere inconvenience. As previously mentioned the property contains 259,895 sq. ft. (5.96 acres) of developable land net of wetlands and right of way. Pursuant to the comprehensive plan and zoning ordinance this is sufficient land area to support 17 lots, based on the required 15,000 sq. ft. minimum size. The requested variances to allow three flag lots will allow the property to accommodate a total of 12 lots that all exceed the 15,000 sq. ft. minimum. Consequently, the result of granting the requested variances is reasonable. Conversely, failure to grant these variances would deny the property owners a reasonable use of their property, as defined by the Comprehensive Plan, zoning ordinance since all of the conditions in Sec. 18-22 have been met. In summary, the conditions that justify the granting of these variances are unique to this property and are distinct from the conditions on any other property in the City. The granting of these variances will allow the property to be developed for single family detached housing in accordance with the comprehensive plan and zoning ordinance. The proposed lots will all meet or exceed the 15,000 sq. ft. minimum lot sizes and will be served by sanitary sewer and water and the neighborhood will be served by new storm water ponding and conveyance systems and will cause no adverse impacts to the public welfare. The proposed variances meet all four required conditions contained in Sec. 18-22 variances. We respectfully request the approval of these variances to allow the property to be put to a reasonable use, consistent with the goals of the comprehensive plan and the purpose and intent of the Chanhassen Zoning Code. SUMMARY AND CONCLUSION The application by Yosemite Holdings LLC is fully consistent with the Chanhassen Comprehensive Plan. The rezoning from RR Rural residential to RSF Single family Residential is also fully consistent with the Comprehensive Plan now that the City has provided municipal utility services to the property. Finally the requested variances to permit three flag lots meet all of the requisite conditions required in Sec.18-22 of the Chanhassen Code. The conditions found on the site go well beyond mere inconveniences and they are unique to this property, The result of granting these variances is reasonable and the proposed subdivision will be fully consistent with the essential character of Chanhassen's single family neighborhoods. We respectfully request approval of our application and we are pleased to bring this fine new neighborhood community to the wonderful City of Chanhassen. ® Stantec 4 * Perimeter property - dimensions, and standard lot width criteria, result in fractional lot size differences and / inefficient land use. / I II I Low Point 1004 Wetland & Buffers / .40, \ 1 High Point; \ 1032 i -i 1 Low Point 1 1002 I I 1 Wetland & s Buffers r I I Culvert/fI I C' IL` oio foint - - - - Lake Lucy Road _ _ _ _ limited c 0' 40' 80' 160' NORTH -------__ V:1938/ACTIVE/1938034)2/GRAPHICS/LAKE LUCY NARRATIVE GRAPHICS.INDD I 1 1 1 1 I I I LIMITING EXISTING CONDITIONS ��° PRACTICAL DIFFICULTIES THAT SATISFY VARIANCE CRITERIA Property, Access, Grades, Wetlands & Buffers Inefficient, mij environmentally disruptive access location II I i The property has an irregular shape due to surrounding subdivision patterns and ownership.

The lots then have to be 100' wide. Lots 5 and 9. The area of the throats are not counted in the lot area of the flag lot. Lots 5 & 9. The width of the lot on a cul-de-sac must be 90 ft at the building setback line. Lot 8. The wetland and buffer shall be shown in outlots. The stormwater pond on the south side should be located in an outlot. At a minimum, it must be covered by a d&u easement. The easement for the trail and d&u on the south side of lot 6 shall be 20'.

I had Ryan digitize the graphic, in order to see how this layout fits the ordinance. We have 4 flag lots, 2 of which need variances. The Flag lots are lots 4,5, 8 and 9. Lots 8 and 9 would require front yard setbacks variances. Also we will be out on the site this week doing PM peak traffic counts for turning movements, this will be used for the queuing determination on the proposed access. • � ! 3e' r��e5 S��,A�. • -- I Ene...

FYI. Sincerely Terry Forbord From: Terry Forbord Sent: Thursday, March 03, 2016 3:24 PM To: Bob Generous (bgenerous@ci.chanhassen.mn.us) Cc: Stephanie Smith (sbsmith@ci.chanhassen.mn.us) Subject: Lake Lucy Rd. I'm sorry I missed your call on March 22nd, my wife and I took our elderly and frail mothers to Florida for what likely is their last vacation. We returned on March 16` I understand Roger Humphrey with Stantec has been in communication with you and that you also have met with him to review our Concept Plan for Lake Lucy Rd. I have appreciated your and Stephanie's cooperation, support and guidance for the necessary variances and sewer access adjustments so we can make this new neighborhood work. Slight modifications/variances/adjustments can make a world of difference when creating great neighborhoods. I've learned from Roger that at the last meeting you somewhat changed course advancing the idea of a private driveway to serve three to four of the homesites in the northwest corner of the neighborhood. This has created significant problems for a host of reasons. Our builders will not enter the project under those conditions due to the many problems private drives as presented can create and the Realtors are very negative. Here are just a few immediate responses to the negative effects of the private drive concept on the following key provisions 1. Hurts curb appeal of homes 2. Makes marketing of home more difficult 3. Negative effect on the appraised value of the homes 4. Creates problems for Waste & Recycling containers & collection trucks 5. Creates problems for Moving & Delivery trucks 6. Greatly increases difficulty in construction operations & deliveries 7. Imposes limitations on guest parking options 8. Creates challenges for mailbox placement & access 9. Creates compounded complications for snow extraction and storage 10. Creates increased HOA Fees for private road maintenance and all necessary legal documentation already burdened due to the lack of efficient access to municipal sewer 11. Exacerbated Public Safety efficiencies We are working on a productive response with better solutions to eliminate these very negative conditions. We sincerely hope to have your continued cooperation and support so we can move this deal forward. We need to resolve this; time being of the essence. We're running out of time and need to get an application before the Planning Commission posthaste. We will get back to you soon with simple solutions that work for the market and should be acceptable to the City Thank you, Sincerely, Terry Forbord Yosemite Holdings LLC Office: (952) 470-5121 Cell: (612) 868-2483 tforbord@forbordusa.com Terry Forbord on Linkedln "The days are long, but the years are short" by - Gretchen Rubin - - "Work hard.
