This determination requires that the septic system be replaced. Due to the location of the house and bluff, the only viable location for a septic system is in the front yard, partially within the city’s right-of-way. The applicant is requesting a variance to place the pump line, tanks, mound, and dispersal area within the 50-foot bluff setback area and 20-foot bluff impact zone and a 10-foot property line setback variance for the mound and dispersal area to accommodate this placement. A variance is required because Chapter 19 requires that septic systems be setback 10 feet from property lines and 50 feet from the top of the bluff, and Chapter 20 prohibits the removal or alteration of vegetation and grading within 20 feet from the top of a bluff. LOCATION: 565 Lakota Lane (PID 251300010) APPLICANT: Francisco & Heather Lynn Silva 565 Lakota Lane Chaska, MN 55318 PRESENT ZONING: A-2 2030 LAND USE PLAN: Residential Low Density ACREAGE: 2.57 DENSITY: NA PROPOSED MOTION: “The Chanhassen Planning Commission recommends that the City Council approve a variance allowing the placement of the pump line, tanks, mound, and dispersal area within the 50-foot bluff setback area and 20-foot bluff impact zone and a 10-foot property line setback variance for the mound and dispersal area.” 565 Lakota Lane Planning Case #2020-7 Page 2 LEVEL OF CITY DISCRETION IN DECISION-MAKING: The city’s discretion in approving or denying a variance is limited to whether or not the proposed project meets the standards in the Zoning 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. PROPOSAL/SUMMARY The applicants recently purchased this property. During the purchasing process, they were informed that the septic system was in a state of non- imminent failure and would need to be replaced. The existing septic system is located within the bluff behind the house, and due to the location of the house and bluff, the only location on the property that can accommodate a new septic system is the northwest corner. This location is within the 50-foot bluff setback, the 20-foot bluff impact zone, and 10-foot property line setback. It will also require the city to issue an Encroachment Agreement allowing a portion of the dispersal area to be located within the right-of-way. The mound for the proposed septic system will be within one foot of the front lot line and the dispersal area will cross the lot line and encroach approximately eight feet into the right-of-way. The mound will also be about 22 feet from the top of the bluff and the dispersal will be around 2 feet from the top of the bluff. The tanks will be located approximately one foot from the top of the bluff, with the sewer line being about five feet from the top of the bluff at its closest point. The applicant has stated that it is not possible to place the septic system on the southern portion of the property and that the proposed northwest corner is the only approved location. The applicant has further noted that they must replace the septic system in a timely manner due to the fact that the system is non-compliant. APPLICABLE REGULATIONS Chapter 1 - General Provisions, Section 1-2, Rules of Construction and Definitions 565 Lakota Lane Planning Case #2020-7 Page 3 Chapter 19 - Water, Sewers and Sewage Disposal, Article IV, Subsurface Sewage Treatment Systems, Sec. 19-67, Amendments Chapter 20 - Zoning, Article II, Division 3, Variances Chapter 20 - Zoning, Article II, Division 4, Nonconforming Uses Chapter 20 - Zoning, Article X, “A-2” Agricultural Estate District Chapter 20 - Zoning, Article XXVIII, Bluff Protection, Sec. 20-1403, Removal or Alteration of Vegetation Chapter 20 - Zoning, Article XXVIII, Bluff Protection, Sec. 20-1404, Topographic Alterations/Grading and Filling Note: Most of the applicable setback standards are located in Chapter 19; however, Chapter 19 does not have a specific variance procedure so the variance is being granted from the general zoning code using the procedure outlined in Chapter 20. BACKGROUND County records indicate that the home was built in 1967. On October 14, 1991, the city passed ordinance number 152, which created the city’s bluff protection ordinance. On August 22, 1994, the city expanded the bluff protection ordinance to cover the entire city. On February 8, 1999, the city passed ordinance number 289, which governed the installation and maintenance of septic systems and established a 20-foot bluff setback. On May 14, 1999, the city issued a permit for a garage addition. On May 23, 2011, the city passed ordinance number 523, adopting Carver County Ordinance 67- 2010 by reference and establishing the current 50-foot bluff setback for septic systems. On November 28, 2016, the city received notice of a non-imminent failing sewage treatment system at 565 Lakota Lane. SITE CONDITIONS The property is zoned Agricultural Estate District (A2) and contains a bluff. This zoning district requires lots to be a minimum of 2.5 acres, have front yard and rear setbacks of 50 feet, side yard setbacks of 10 feet, and limits parcels to a maximum of 20 percent (20%) lot coverage. Structures are required to be 30 feet or the existing distance from the top of the bluff, with no topographic or vegetative alterations permitted within 20 feet from the top of the bluff. Chapter 19 requires septic systems to be setback 50 feet from bluffs and 10 feet from property lines. 565 Lakota Lane Planning Case #2020-7 Page 4 The existing house structure is approximately 34 feet from the front property line, with a front patio about 27 feet from the front property line, and the home is setback around six feet from the top of the bluff. The existing septic system is located within the 50-foot bluff setback and 20-foot bluff impact zone. There is also a shed located on the bluff. The property meets all other requirements of its zoning district. NEIGHBORHOOD Bluffview Addition The plat for this area was recorded in November of 1958. This plat predates the formation of the city and since the plat was recorded, the zoning code was adopted and amended multiple times, including provisions governing the location of structures and septic systems relative to bluffs. The homes in the area are of older construction, built between 1964 and 1984, and most do not conform to the city’s current bluff ordinance. Variances within 500 feet: 1974-03 535 Lakota Lane: Road Realignment as part of a subdivision - Approved* 1982-05 608 Flying Cloud Drive: Development in unsewered lot (Recreational Water Slide) - Denied *From the file it is not clear why realigning the road required a variance and was not just handled as part of the subdivision. ANALYSIS Proposed Location 565 Lakota Lane Planning Case #2020-7 Page 5 As the above illustration shows, the majority of the northern section of the property is encumbered by the 50-foot bluff setback and once the locations of the house, well, and existing septic line are taken into account, the northwestern corner of the lot is the possible location for a septic system. The applicant has moved the system as close to the northern lot line as possible in order to minimize the encroachment into the bluff impact zone and has positioned the mound outside of the most sensitive area of the bluff; however, this location has resulted in the mound being located one foot from the front lot line and its dispersal area extending into the right-of-way. Typically, staff is strongly opposed to anything being located within the right-of-way; however, in this case the proposed encroachment is a subsurface rock bed that should not include any other underground components. Due to the minimally intrusive nature of the proposed encroachment, the Engineering Department has indicated that they would be willing to grant an Encroachment Agreement to permit the installation of the rock bed within the right-of-way. The Engineering Department’s full comments and required conditions can be found in the attached memo. While staff would prefer that nothing be located within the bluff impact zone, staff recognizes that in this case it is simply not possible to design a system that will maintain a 20-foot setback from the top of the bluff. Staff also recognizes that the portions located within the bluff impact zone are all subsurface in nature and should not pose a risk to the integrity of the bluff, provided adequate precautions are taken during construction and that the area is revegetated post construction. 565 Lakota Lane Planning Case #2020-7 Page 6 Due to the lack of alterative locations and the in recognition of the fact that the proposed location minimizes to the intent practicable the impact on the bluff, staff recommends approving the required variances. Southern Location The slope near the southwestern corner of the property does level off enough that a septic system could theoretically be sited; however, there is no practical way to access that location. In order to install a system in that location, the installer would either have to traverse approximately 500 feet of steep slopes, significantly disrupting the existing vegetation, or obtain permission to bring equipment in through the Hennepin County Regional Railroad authority’s property to the south of 565 Lakota Lane. Staff does not believe it would be possible for the homeowner to obtain permission to bring equipment in though the bike and pedestrian trail, and accessing the southwestern corner of the property from Lakota Lane is not practical. For these reasons, staff agrees with the homeowner’s statement that the northwest corner of the property is the only viable location for a new septic system. Impact on Neighborhood The largest impact on the neighborhood would be the anticipated loss of trees in the proposed location of the rock bed within the city’s right-of-way. While the loss of tree screening is regrettable, 4 of the 10 houses on Lakota Lane are readily visible from the road and the loss of 565 Lakota Lanes vegetative buffer will not be a radical departure from the street’s existing aesthetic. Since most components of the septic system are below ground, it is not expected to have a significant impact on the neighborhood. SUMMARY Staff believes that the proposed location is the only viable location for a new septic system on the property and that the applicant has made every effort to locate the system as far as possible from the top of the bluff. Staff also believes that the proposed system and its location will have a minimal impact on the surrounding properties. RECOMMENDATION Staff recommends that the Chanhassen Planning Commission recommend that the City Council approve a variance allowing the placement of the pump line, tanks, mound, and dispersal area within the 50-foot bluff setback area and 20-foot bluff impact zone and a 10-foot property line setback variance for the mound and dispersal area, subject to the conditions of approval and adopt the attached Findings of Fact and Recommendation: 565 Lakota Lane Planning Case #2020-7 Page 7 1. The applicant must apply for and receive all necessary permits from the relevant agencies. 2. The applicant must show proposed erosion control on survey and install erosion control as needed to prevent offsite erosion. 3. The septic system must be located as proposed in the survey and design received by the city on May 1, 2020 as part of the variance request. 4. The property owner shall enter into an Encroachment Agreement with the city for the area of the individual sewage treatment system (septic system) that encroaches into the public easement. The final area of encroachment shall be determined by an as-built survey of the septic system, and the Encroachment Agreement shall be recorded prior to issuance of the Certificate of Compliance. 5.

Public Hearing Notice and Affidavit of Mailing G:\PLAN\2020 Planning Cases\20-07 565 Lakota Lane VAR\Staff Report-565 Lakota Lane_PC.doc 1 CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA FINDINGS OF FACT AND RECOMMENDATION (APPROVAL) IN RE: The application of Francisco and Heather Lynn Silva for the installation of a septic system within the required bluff setback, impact zone, and front setback on a property zoned A2 - Planning Case 2020-07. On June 2, 2020, the Chanhassen Planning Commission, acting as the Board of Appeals and Adjustments, met at its regularly scheduled meeting to consider the application. The Planning Commission conducted a public hearing on the proposed variance preceded by published and mailed notice. The Board of Appeals and Adjustments makes the following: FINDINGS OF FACT 1. The property is currently zoned Agricultural Estate District (A2). 2. The property is guided in the Chanhassen Comprehensive Plan for Residential Low Density. 3. The legal description of the property is: Lot 1, Bluffview Addition 4. 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 intent of the city’s bluff protection ordinance is to ensure that vegetation and soils located near and on bluffs are not distributed in a manner that has the potential to create erosive conditions or otherwise negatively impact the bluff. The configuration of the property and location of the existing home make it impossible to place a septic system on the property outside of the required bluff setback. The applicant has proposed a placement as far as possible from the top of the bluff in order to minimize the impact on the bluff impact zone. Staff believes that the proposed location will have a minimal impact on the integrity of the bluff. The city also requires septic systems to be setback from property lines and road right of ways in order to minimize the potential for these systems to negatively impact adjacent property owners or interfere with the installation of utilities or other features commonly found in right of ways. In this case, the Engineering Department believes that the rockbed 2 can be located within the right-of-way without interfering with the function of the right- of-way. Additionally, by granting a variance to the property line setbacks, the required bluff setback variance is minimized and the septic system can be placed further away from the top of the bluff. Granting a variance to allow a single-family home with no ability to hook up to municipal utilities to install a septic system is consistent with the comprehensive plan, and the proposed variance is in harmony with the intent of the zoning code. 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: Due to the existence of bluffs on the property, the dimensions of the property, the placement of the house, nature of the contours, and characteristics of the soil, the septic system must be placed in the northwest corner of the property. This placement requires variances from the bluff setbacks, impact zone, and property line setbacks. City sewer and water will not be available for the property in the near future and a functioning septic system is required to have reasonable use of the property c. That the purpose of the variation is not based upon economic considerations alone. Finding: The variance request is not solely based upon economic considerations. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The lot is a non-conforming lot of record that was created before the existing district standards, bluff protection, and septic system ordinances were created. e. The variance, if granted, will not alter the essential character of the locality. Finding: Many components of the septic system would be located below grade and would not be expected to have any visual impact on the neighborhood. While the proposal will likely require the removal of several trees within the city’s right-of-way, almost half of the other homes along Lakota Lane are easily visible from the road and this would not represent a departure from neighborhood standards. The surrounding residential properties are also located on large lots and are served by septic systems. 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 does not apply to this request. 5. The planning report #2020-07, dated June 2, 2020, prepared by MacKenzie Young-Walters, is incorporated herein. 3 RECOMMENDATION “The Chanhassen Board of Appeals and Adjustments recommends that the City Council approves the placement of the pump line within the 50-foot bluff setback area and the 20-foot bluff impact zone, a 30-foot bluff setback variance for the tanks and a 20-foot bluff and 9-foot property line setback variance for the mound and dispersal area, subject to the conditions of approval: 1. The applicant must apply for and receive all necessary permits from the relevant agencies. 2. The applicant must show proposed erosion control on survey and install erosion control as needed to prevent off-site erosion. 3. The septic system must be located as proposed in the survey and design received by the city on May 1, 2020 as part of the variance request. 4. The property owner shall enter into an Encroachment Agreement with the city for the area of the individual sewage treatment system (septic system) that encroaches into the public easement. The final area of encroachment shall be determined by an as-built survey of the septic system, and the Encroachment Agreement shall be recorded prior to issuance of the Certificate of Compliance. 5. All underground components encroaching into the public easement and identified in the Encroachment Agreement shall be detectable by customary locating equipment (i.e. the installation of tracer wire). The tracer wire shall be tested and approved prior to issuance of the Certificate of Compliance. ADOPTED by the Chanhassen Planning Commission this 2nd day of June, 2020. CITY OF CHANHASSEN BY: Steve Weick, Chairman 1 CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA FINDINGS OF FACT AND RECOMMENDATION (DENIAL) IN RE: The application of Francisco and Heather Lynn Silva for the installation of a septic system within the required bluff setback, impact zone, and front setback on a property zoned A2 - Planning Case 2020-07. On June 2, 2020, the Chanhassen Planning Commission, acting as the Board of Appeals and Adjustments, met at its regularly scheduled meeting to consider the application.

Finding: The intent of the city’s bluff protection ordinance is to ensure that vegetation and soils located near and on bluffs are not distributed in a manner that has the potential to create erosive conditions or otherwise negatively impact the bluff. It would not be in line with the intent of this Chapter to allow the removal of vegetation and grading/earthmoving activities within the bluff impact zone which could create erosive conditions or destabilize the slope. Additionally, the city requires the dedication of right-of-way to accommodate use of public infrastructure including roadways, sewer/water infrastructure, cable/power lines, and other uses. Roadway right-of-way also is intended to allow for the maintenance, expansion, and realignment of existing roadways. Encumbering this area with a privately owned septic system would not be in line with the City Code intent in requiring the dedication of public right-of-way. 2 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.

That the purpose of the variation is not based upon economic considerations alone. Finding: The variance request is not solely based upon economic considerations. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The lot was platted, house built, and septic system installed before the adoption of the current City Code governing bluffs and septic system setbacks. e. The variance, if granted, will not alter the essential character of the locality. Finding: The proposed septic system location would require the removal of multiple trees that screen the house from traffic on Lakota Lane. Replacing these trees with a septic system mound located one foot from the property line would significantly alter the appearance of the property. 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 does not apply to this request. 5. The planning report #2020-07, dated June 2, 2020, prepared by MacKenzie Young-Walters, is incorporated herein. 3 RECOMMENDATION “The Chanhassen Board of Appeals and Adjustments recommends that the City Council deny the variance request to place the pump line, tanks, mound, and dispersal area within the 50- foot bluff setback area and 20-foot bluff impact zone and deny the 10-foot property line setback variance for the mound and dispersal area, and adopt the attached Findings of Fact and Decision.” ADOPTED by the Chanhassen Planning Commission this 2nd day of June, 2020.

Your septic system is designed to kill harmful organisms and rcmove pollutants before the water is recycled back inlo our lakes, streams and groundwater. This management plan will identiry the operation and maintenance activilies necessary to ensure long- lerm performance of your septic system. Some of these activities must be performed by you, the homeowner. Other tasks must be performed by a licensed septic maintainer or service pmvider- However, it is YOUR rcsponsibility to make sure all tasks get accomplished in a timely manner. The University of Minnesota's Seplic System Owner's Guide contains additional tip6 and recommendations designed to extend the effecrive life ofyour syslem and save you money over time.

Check (listen, look) for leaks in toilets and dripping faucets. Repair leaks promptly. o Swfacing sewage. Regularly check for wet or spong/ soil amund your soil treatment area. If surfaced sewage or strong odors are not corrected by pumping the tank or fixing bmken caps, call your service professional. Untreated sewage may make humans and animals sick- o Alarms. Alarms signal when therc is a problem; contact your maintainer any time the alarm signals. o Lint fher. If you have a lint filter, ctreck for lint buildup and clean when necessary. Consider adding one after washing machine. a EflIuent screen. lf you do not have one, consider having one added the next time the tank is cleaned. Annuelly o Vater usage rale. A water meter can be used to monitor your average daily water use. Compare your water usage rate to the design flow of your system (listed on lhe next page). Contact your septic professional if your average daily flow over the course of a month exceeds 70olo of the design flow for your system. o Caps.Make sure that all caps and lids are intact and in place. Inspect for damaged caps at least every fall. Fix or rcplace damaged caps before winter to help prcvent freezing issues. o lYater conditioning devices- See Page 5 for a list of devices. When possible, pmgram the recharge frequency bced ot water demand (gallont) ralhet lh^n time (days). Recharging too frequently may negatively impact your septic system. a Reeiew your water usoge rare. Review the Water Use Appliance chart on Page 5.

Memorandum To: MacKenzie Young-Walters, Associate Planner From: Erik Henricksen, Project Engineer CC: Charles Howley, Public Works Director/City Engineer Eric Tessman, Building Official Date: 5/13/2020 Re: Setback Variance at 565 Lakota Lane – Planning Case #2020-07 The Engineering Department has reviewed the Variance submittal for 565 Lakota Lane. These comments are divided into two categories: general comments and proposed conditions. General comments are informational points to guide the applicant in the proper planning of public works infrastructure for this project, to inform the applicant of possible extraordinary issues and/or to provide the basis for findings. Proposed conditions are requirements that Engineering recommends be formally imposed on the developer in the final order. Note that references to the “City Standards” herein refer to the City of Chanhassen Standard Specifications and Detail Plates. General Comments/Findings 1. Any and all utility and transportation plans submitted with this application have been reviewed only for the purpose of determining the feasibility of providing utility, transportation facilities, and right-of-way management for the project in accordance with City Standards. A recommendation of variance approval does not constitute final approval of details, including but not limited to alignments, materials and points of access, connection or discharge, that are depicted or suggested in the application. The applicant is required to submit detailed construction drawings and/or plat drawings for the project, as applicable. The City of Chanhassen Engineering and Public Works Department will review plans, in detail, when they are submitted and approve, reject or require modifications to the plans or drawings based upon conformance with City Standards, the Chanhassen Code of Ordinances and the professional engineering judgment of the City Engineer. 2. It is the opinion of the Engineering Department that the proposed 565 Lakota Lane setback variance for the installation of an individual sewage treatment system (septic system) can be approved (as it pertains to Engineering and Public Works requirements), provided it fully addresses the comments and conditions contained herein. 3. The applicant is proposing to construct a septic system near the northwest corner of the property located at 565 Lakota Lane due to the lack of public sanitary sewer system in the area. The proposed location chosen is due to the topographic constraints of the site, as a majority of the property is a bluff. The proposed location appears to be the most feasible based on aerial reviews and the need to keep the septic system as far from the bluff as possible. Additionally, the applicant has provided percolation tests, soil borings and appropriate septic system designs showing the feasibility of the area where the proposed septic system is to be constructed. However, due to the design requirements of the above grade septic system coupled with the need to maintain the furthest setback from the bluff as feasibly possible, a portion of the system will have to encroach into public easements. See conditions 1 and 2. Proposed Conditions 1. The property owner shall enter into an Encroachment Agreement with the City for the area of the individual sewage treatment system (septic system) that encroaches into the public easement. The final area of encroachment shall be determined by an as-built survey of the septic system, and the Encroachment Agreement shall be recorded prior to issuance of the Certificate of Compliance. 2. All underground components encroaching into the public easement and identified in the Encroachment Agreement shall be detectable by customary locating equipment (i.e. the installation of tracer wire). The tracer wire shall be tested and approved prior to issuance of the Certificate of Compliance. MEMORANDUM TO: MacKenzie Young-Walters, Associate Planner FROM: Jill Sinclair, Environmental Resources Specialist DATE: June 2, 2020 SUBJ: 565 Lakota Lane, Variances to construct a septic system Staff supports the request for a variance to construct a septic system in the front yard. This option has the least amount of tree removal and environmental impact on the lot. The rear yard locations, while possibly not requiring variances, would have significant tree removal and potential impact on a bluff area.

SUMMARY OF REQUEST In 2009, the city passed Ordinance 488 which allowed for the creation of regional/lifestyle center commercial PUDs. Regional commercial centers are intended to be walkable mixed­use districts with both residential and regional commercial/office components. In order to ensure that these districts did not develop as primarily residential districts with neighborhood­level supporting commercial uses, the city restricted the percentage of the development that could be developed for residential uses and required that the residential developments not be constructed before the commercial uses. In the decade since this ordinance was passed, the retail environment has changed significantly. Consumers have shown a strong preference for experiential pedestrian­oriented retail destinations and there is a growing realization that the residential component of a regional commercial center plays an important role in creating the demand for its commercial elements. Since other portions of the city’s PUD ordinance, specifically Section 20­509’s intent clauses, also ensure that these PUDs will serve a regional commercial function, staff believes the residential percentage and phasing requirements are unnecessarily restrictive.

BACKGROUND The city first considered the creation of a regional commercial center as part of the 2030 Comprehensive Plan. During the process of researching and drafting the 2030 Comprehensive Plan, the city realized that there was the potential for a regional commercial center to be created at the intersection of Powers and Lyman Boulevards within the city. In order to facilitate this potential use, the 2030 Comprehensive Plan guided the land in question for both commercial and office use and passed Ordinance 488, which established the framework for creating a regional commercial PUD. Subsequent studies reinforced the viability of a regional commercial center in this location, and the city approved a concept PUD for a 70­acre regional commercial center in 2015. This project ultimately did not go forward, and the city approved a second concept PUD for a 118­acre regional commercial center 2016. This proposal was accompanied by an update to the area’s Alternative Urban Areawide Review. The City Council passed the PUD ordinance creating the Avienda Lifestyle Center on July 10, 2017. This PUD included provisions allowing for up to 30 percent of the development to be developed for residential uses. On June 2, 2020, the Planning Commission will conduct a hearing to consider amendments to the Avienda Lifestyle Center’s PUD. RECOMMENDATION Staff recommends that the city remove the 20 percent cap from regional commercial centers and allow the residential component to be constructed before the commercial component. Lifestyle centers would still be subject to the standards and guidelines contained in Section 20­509.

The applicant is proposing a mixed-used development. The following is from the applicant’s Development Plan. Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 4 of 23 VISION The land use change to either Office or Regional Commercial District as a part of the 2030 Comprehensive Plan was based on the city’s vision for a lifestyle center. The Comprehensive Plan states: 2.7.4 Regional/Lifestyle Center Commercial Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 5 of 23 “Definition/Vision: A mixed commercial district with retail and entertainment uses of a scale and function that serves a regional market. The physical environment emphasizes an attractive, comfortable walking experience for shoppers and visitors and is designed to serve trail users and mass transit as well as automobile traffic. Centers of this type have at least two major retail anchors and are characterized by the diversity and mix of retail and service uses within their boundaries. Uses within this district should complement existing retail users in the other commercial districts. Development of these centers shall be planned as a group of organized uses and structures to accommodate a sensitive transition between commercial activities such as loading, parking of automobiles, lighting and trash collection, and surrounding residential uses. Such centers shall be designed with one theme, with similar architectural style, similar exterior building materials, and a coordinated landscaping theme. Vehicle and pedestrian access is coordinated and logically linked to provide a comprehensive circulation system. Goods and Services Examples • Entertainment • Department Store • Comparison Shopping • Specialty Retail/Boutique • Restaurants • Hotels • Residential A new zoning district Regional Commercial (RC) will be created in the City Code to implement this land use. The city has given a dual land use of the 118+/- at the southeast corner of Powers and Lyman Boulevards to accommodate this use. PLANNING DEPARTMENT COMMENTS When the city was considering the land use change on the site in 2006-07, there was much discussion about this area having uses different from the downtown. The downtown area is intended to be the uses that meet the daily needs of residents, and the regional mall site was envisioned to be those uses that would be more of a comparison shopping that would serve a regional market including: Goods and Services Examples • Entertainment • Department Store • Comparison Shopping • Specialty Retail/Boutique • Restaurants • Hotels • Residential Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 6 of 23 The intent of this district: The use of planned unit developments for regional/lifestyle center commercial purposes should result in a reasonable and verifiable exchange between the city and the developer. This district is intended to provide for the development of regional and community scale integrated retail, office, business services, personal services and services to the traveling public near freeway interchanges. The most significant changes from the previous plan is the increase of housing units from 20 to 30 percent. The permitted uses in Avienda Village are all uses that would be part of a vibrant lifestyle center and as anticipated in the Comprehensive Plan. The following categories of uses were anticipated in the Comprehensive Plan and the listed uses should be permitted to ensure the success of the lifestyle center (see attached Exhibit A for PUD Design Standards): Developers District Master Plan The development Master Plan identifies five distinct sub-districts within Avienda. Each of these sub-districts (outlined on the plan above) is defined by specific site development patterns and perhaps a distinctive character or image. The sub-districts complement one another as part of the overall plan. They include: Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 7 of 23 • Sub-District 1 - Retail - Provides a location for larger-scale in-line and stand-alone retail and entertainment uses. • Sub-District 2 - The Village - Provides the broadest variety, highest density and greatest intensity of development, encouraging both vertical and horizontal mixed use. • Sub-District 3 - Mixed Use - Provides a location for smaller-scale retail, service and other auto-oriented uses as well as hotels and medical/technology related uses • Sub-District 4 - Multi-Family- Provides opportunities for high density senior or rental apartments. • Sub-District 5 - Low Density Residential - Provides opportunities for small lot homes. AMENDED PRELIMINARY PLAT Avienda encompasses 118.00 acres. It includes 19 buildable lots and 3 outlots. Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 8 of 23 TRAFFIC STUDY The traffic study completed with the AUAR Update indicated that the following intersections will meet signal warrants with the development: Lyman Boulevard and Audubon Road N., Lyman Boulevard and Sunset Trail, and Powers Boulevard (CR 17) and Pioneer Trail. The developer shall work with Carver County on the installation of these signals and any other improvements necessary. The developer shall fund the installation of these signals and improvements per Carver County’s cost share policy. STREETS The proposed street plan is consistent with the AUAR Update, although modifications have been made to Avienda Parkway. Previously, Avienda Parkway looped around the inside of the development. The modification cut the loop in half. After review, staff finds that the required Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 9 of 23 connectivity addressed in the AUAR Update is still being met with the proposed street layout, and the modification decreases the amount of right-of-way the city would have to maintain. Bluff Creek Boulevard connects to the intersection with Powers Boulevard and the TH 212 ramp. The connection to Sunset Trail is made to the north, and the connection to The Preserve at Bluff Creek development is made by extending Mills Drive. These connections are tied together by the proposed Avienda Parkway. The applicant shall show the road profiles and a horizontal alignment table in the plan set for all public roads prior to final plat. The plans for public streets shall be deigned to Municipal State Aid Standards and approved by the Minnesota Department of Transportation. The public roads constructed with this development are: Bluff Creek Boulevard, Avienda Parkway, Sunset Trail and Mills Drive. All other roads and drives constructed with this development will be privately owned and maintained. All public streets are proposed to have a speed limit of 30 mph. As large, landscaped boulevards are proposed, the applicant shall add a note to the typical sections to identify a corridor for installation of private utilities such as buried power, communication, gas, etc. Bluff Creek Boulevard The extension of Bluff Creek Boulevard is proposed to have a similar cross section to the existing segment it connects to; one lane each direction with a treed median. The thru lane width varies with turn lanes at intersections. Roundabouts will be constructed at the intersection with Avienda Parkway along with a roundabout for the future build-out of private accesses just west of Powers Boulevard and Bluff Creek Boulevard. These roundabouts promote traffic calming while carrying the anticipated volumes of traffic. The extension of Bluff Creek Boulevard will be a minor collector, per the 2040 Comprehensive Plan. Avienda Parkway Avienda Parkway is proposed to be a 36-foot wide roadway with a two-way left-turn lane. A roundabout will be constructed at the intersection with Sunset Trail. Staff recommends the applicant look at adding traffic calming measures to Avienda Parkway at Lots 1 and 2, Block 3 and Lot 9, Block 4. Specifically, the applicant shall look to incorporate pedestrian-friendly crossing features to the intersections at Mills Drive and Avienda Parkway, and where private drives intersect Avienda Parkway. Mills Drive The applicant shall ensure the width of Mills Drive matches with the existing Mills Drive section in The Preserve at Bluff Creek. The extension of Mills Drive is required to provide a secondary access to The Preserve at Bluff Creek development, which is an approximately 2000-foot long Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 10 of 23 cul-de-sac that currently has a temporary emergency access onto Lyman Boulevard. The developer of The Preserve at Bluff Creek 6th Addition will remove the temporary emergency access onto Lyman Boulevard once the Mills Drive connection is constructed. Further review of the final design and alignment of Mills Drive and any proposed private drives will be evaluated prior to final plat. A traffic study may be required to ensure adequate access management guidelines are adhered to. Sunset Trail Sunset Trail is a 44-foot wide roadway that consists of two 15-foot thru lanes and a 14-foot turn lane and serves as the northern access to the site off Lyman Boulevard. The east and south leg of the roundabout will be private streets to accommodate access through the center of the development while the west leg is the connection to Avienda Parkway. When future lots apply for site plan approval, these private streets will be constructed. STREET LIGHTING The applicant has not submitted a street lighting plan at this time. The project shall include street lighting per City Code. Decorative street lights are permissible with a maintenance agreement. SIDEWALKS AND TRAILS The applicant proposes a series of public and private trails and sidewalks throughout the development. All proposed trails and sidewalks within the public right-of-way will be owned and maintained by the city and shall adhere to the city’s standard specifications and details. All other pedestrian walks and corridors will be privately owned and maintained. ADA-compliant pedestrian ramps shall be constructed at all intersections and median refuges per the MnDOT standard details. RETAINING WALLS No retaining walls are proposed with the initial phase of this development, however it is possible that several retaining walls will be required around two perimeter locations to the north in subsequent phases of the development. If retaining walls will be installed in subsequent phases they shall be privately owned and maintained. As these potential retaining walls would be greater than four feet, they must be constructed in accordance with plans prepared by a registered engineer and be constructed of a durable material (smooth face concrete/poured in place, masonry/mortared, railroad ties and timber, and boulders are prohibited). Also, a fence or other barrier is required at any location where a wall is greater than 6 feet tall and within 10 feet of a public right of way. Staff recommends the applicant work with residents of The Preserve at Bluff Creek to remove the retaining wall along the shared property line and replace with a graded berm. Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 11 of 23 SANITARY SEWER MAIN The plans show two separate sanitary systems to service this development. The first will ultimately service portions of Block 4 and the homes proposed for Lot 1, Block 2 and Lot 1, Block 3 from a stub constructed near the northeast corner of the site. The homes shall tie-in to the 8-inch PVC sanitary main proposed under Mills Drive and the abutting private street. An 8-inch stub will be constructed to Sunset Trail and Lyman Boulevard for future extension to service the existing parcels on Sunset Trail north of Lyman Boulevard. The rest of the development will be serviced by sanitary sewer that will extend from the stub under existing Bluff Creek Boulevard. The sanitary main will be constructed under Bluff Creek Boulevard and Avienda Parkway and will consist of 8-inch diameter PVC. Sanitary structures along Bluff Creek Boulevard shall be moved out of the landscaped median and into the center of the eastbound travel lane for future maintenance access considerations. Further review of the final placement of the sanitary sewer main and its appurtenances will be conducted prior to final plat in order to ensure adequate easements for future maintenances activities. All sanitary sewer main constructed within the right-of-way in this project shall be publically owned and maintained. Private sanitary main must be constructed to meet the city’s requirements for public utilities. The plans shall use the most recent Chanhassen standard detail plates and specifications, which are available on the city’s website. The previously proposed design grades for sanitary pipe were set at the minimum slopes per the 10-State Standard for design. However, staff advised that setting the design grade to this minimum is not advisable. The plan must have a design grade that the developer and engineer are confident that the construction process will achieve the minimum. If the grade is flatter than the 10-State Standard at the time utility acceptance is requested, the city will require the sanitary sewer be excavated and reconstructed to meet the grade requirement. Staff recommended use of design grade 0.10% above the required minimum, which the new plans have incorporated. WATER MAIN Water main for the development is proposed to connect from a 12” stub under the existing Bluff Creek Boulevard. The developer proposes 12” PVC C900 water main to be extended under Bluff Creek Boulevard and Avienda Parkway, with an 8” main constructed under Sunset Trail for future extension. A 12” connection from the intersection of Bluff Creek Boulevard and Powers Boulevard will loop the internal water system. The development will be required to complete the water main loop abutting the north property line along Lyman Boulevard which was previously stubbed pending future development. Additional water main stubs to serve the interior of the development have been proposed and shall be provided by the developer. Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 12 of 23 Water main constructed within the right-of-way in this project shall be publically owned and maintained. All water main throughout the development must be constructed to meet the city’s requirements for public utilities. The plan shall use the most recent Chanhassen standard detail plates and specifications, which are available on the city’s website. Further review of the final placement of the water main and its appurtenances will be conducted prior to final plat and/or permitting in order to ensure adequate easements for future maintenances activities. STORMWATER The applicant has submitted a stormwater management report produced by Steven E. Sabraski, P.E. (MN License No. 47165) with Landform, dated May 1, 2020. The applicant proposed treatment of stormwater runoff with the use of pretreatment devices such as hydrodynamic separators, sump manholes with baffles, or water quality settlement basins prior to discharge to open air filtration/infiltration basins. As development continues to build-out and as parcels are developed, the basins will be converted to underground rock beds with distribution piping to provide the requisite filtration/infiltration capacity. The developer is proposing to take ownership and maintenance responsibilities of all stormwater facilities throughout the entire development. The report provides analysis and modeling results (HydroCAD, P8, etc.) that illustrates the feasibility of the overall design and meets the most restrictive rules of the underlying jurisdictional bodies (city, Riley Purgatory Bluff Creek Watershed District, the Minnesota Pollution Control Agency, etc.): • Rate Control – proposed discharge rates do not exceed the existing rates for the 2-year, 10-year, 100-year, 24-hour rainfalls and the 10-day, 100-year snow melt. • Water Quality – design modeled to illustrate the city’s non-degradation rules are met along with MPCA requirements for removing TSS and TP. • Volume Abstraction – the design abstracts 1.1 inches of runoff from the impervious areas (ultimately 60.81 acres) of the site. • Storm Sewer Pipe – sized adequately to convey for a 10-year storm. • Emergency Overflows – sized adequately for extreme events. • Low Floor Elevations – at least 3.0 feet above the 100-year HWL and 1.5 feet above the emergency overflows. The applicant has submitted the updated plans to Riley Purgatory Bluff Creek Watershed District (RPBCWD) to ensure their previous approvals from the district are still met. Ultimately, all conditions, comments, and applicable permits required by RPBCWD and other underlying jurisdictional bodies shall be adhered to, including Article VII, Chapter 19 of the City Code. ASSESSMENTS The home units must pay a water and sanitary service partial hook-up fee when Lots and Blocks are replatted at the rate in place at that time. The remaining hook-up fees would be paid with the building permits. Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 13 of 23 The developer shall work with the Building Department to determine the city SAC and WAC fees for commercial and multi-family buildings. The hook-up fees for commercial and multi- family buildings are due with the building permit at the rate in place at that time. The developer shall pay this site’s portion of the 2005 AUAR costs, which is $25,836.70, with the final plat. The developer shall escrow funds for installation of traffic signals at Sunset Trail, Powers Boulevard and Audubon Road. The escrow amount shall be based on Carver County’s cost participation policy as published on their website. WETLAND ALTERATION PERMIT Level 7 Development, LLC, received a Wetland Conservation Act (WCA) permit from the City of Chanhassen as the Local Government Unit (LGU) for the WCA. The developer was approved to impact 4.4659 acres of WCA regulated wetland. Information on the Wetland Alteration Permit can be found on the city’s website in the Avienda Development page. • The project impacts the following wetlands: Wetland Number Wetland Type Wetland Acreage Impact Acreage (fill and excavate) Fill or Excavate Wetland Management Class Wetland 1 1, 3 1.001 1.001 F Manage 2 Wetland 1/2 1, 2 0.1860 0.1860 F Manage 2 Wetland 2 1, 2, 5 2.2569 2.2569 F Manage 2 Wetland 3 1 0.6696 0 NA Manage 2 Wetland 4 1 0.1253 0.1253 F Manage 2 Wetland 5 1 0.3483 0.3483 F Manage 3 Wetland 6 1 0.2514 0.2514 E (for pond) Manage 2 Wetland 7 1 0.0150 0.0150 F Manage 3 Wetland 8 1 0.0844 0.0844 F Manage 3 Wetland 9 1 0.0985 0.0985 E (for pond_ Manage 3 Wetland 10 1 0.0740 0 NA Preserve TOTAL 5.2095 4.4659 Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 14 of 23 ARTICLE XXXI. - BLUFF CREEK OVERLAY DISTRICT With the approval of the 2017 Preliminary Plat, the City Council approved the CUP to allow grading for the connection of Bluff Creek Boulevard.

All buildings and other structures including parking shall be outside the Bluff Creek Overlay District. The developer shall comply with the with the 40-foot primary zone setback and preserve or create a 20-foot buffer from the primary zone. f. The buffer will be required to have a vegetation management plan and soil amendments. Landscaping Comments The design narrative submitted by the applicant references resilient plantings and responsible resource use as goals and standards of the development. To this end, it is expected that proposed landscaping and preserved green space exemplify the latest best management practices. In this regard, tree preservation, boulevard and foundation plantings, turf expanses, and irrigation needs should demonstrate a higher standard than the average residential/commercial/office development. Including topsoil and soil amendments to insure healthy plantings, specifying Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 15 of 23 landscape plants that are suited for the site conditions, installing a reuse irrigation system, including specifications for the irrigation system, incorporating parking lot raingardens, and minimizing impact to the Bluff Creek Overlay Primary Zone will all assist with elevating the project standards. The lower southwest corner of the site is part of the Bluff Creek Overlay District, an area intended for preservation and restoration. This wooded corner within the Primary Zone contains a native upland forest dominated by oaks, but also filled with elms, basswood, black cherry and ash. This area serves as a stormwater, habitat, clean air and carbon sequestration management area. According to city ordinance, ‘the purpose of the District is to protect the Bluff Creek Corridor, wetlands, bluffs, and significant stands of mature trees; promote innovative development techniques such as cluster development and open space subdivisions…’ With this intent, the developer has placed a Conservation Easement over the area to protect it in perpetuity and is in the process of recording the easement. Staff recommends that monument signs indicating the Bluff Creek Overlay District be placed at every property corner and angles with no more than 150 feet apart. The proposed landscape plan submitted includes boulevard plantings within and along the public collector roads. The existing Bluff Creek Boulevard incorporates landscaped medians and roundabout as well as boulevard trees along the trails. The city’s experience with the existing landscaping along Bluff Creek Boulevard has proven to be a higher maintenance input than other streets within the community. The landscape medians work well enough when they are planted with trees and mulched. Including shrubs and perennials creates maintenance needs that burden ongoing management for streets and parks. Trash that becomes trapped in the plantings, weed growth among the plantings, pruning and plant replacement all become continuing maintenance issues and frustrate the neighbors and the city. Staff recommends that any median landscaping be kept simple and low maintenance if it is within the public right-of-way. The boulevard tree landscape plan will need to be expanded to meet species diversity as guided by city ordinance. The city allows no more than 20% of the total trees should be from any one genus and no more than 10% should be from any one species. Additionally, species selection should be based on the site conditions – clay, alkaline, droughty soils. Parking lot, perimeter, foundation, and open space landscaping will need to meet minimum city requirements and, ideally, exceed those requirements. As drawn on the submitted plans, the parking lot design is denoting only half as many landscape islands as would be required by ordinance. Installing only 50% of the landscaping leaves large expanses of unadorned, heat- accumulating, blank pavement. The intent of city ordinances is to eliminate vast, unaesthetic parking areas. This site is ideal for incorporating resilient landscaping that serves to create a pleasing environment, trap stormwater and reduce water use. Large planting beds that can act as stormwater features and allow for optimal tree and plant growth as well as elevated aesthetics should be incorporated. Maplewood Mall should serve as an example of parking areas that endeavor to minimize the detrimental effects of impervious surfaces. For a local example, the Planning Commission Preliminary Plat and Planned Unit Development – Planning Case 2017-10 June 2, 2020 Page 16 of 23 Chaska Curling Center has successfully designed a parking lot that includes aesthetically pleasing landscaping treatments as well as stormwater management. If the proposed plan remains committed to individual landscape islands, then silva cells, engineered soil or other accommodations must be used in order to insure the survival of the trees. A reuse watering system should be considered to irrigate plantings. With the amount of impervious surface on site, adequate reservoirs of stormwater runoff will exist to serve the irrigation needs of the site. Foundation plantings will be expected for all buildings on site and residential landscaping requirements will also need to be met for those specific areas. To meet the design goals as stated in the narrative, overall tree cover should be at least 20-25% or higher in commercial areas and a minimum of 30-35% or higher in residential areas. Carver County Comments (from letter dated May 21, 2020) Carver County has submitted a letter regarding compliance addressing access controls on to county roads. This letter is similar to the letter from the 2017 preliminary approval. The developer will be required to adhere to the county’s conditions. Minnesota Department of Transportation (MnDot) Letter (dated May 20, 2020) The Minnesota Department of Transportation has submitted a letter regarding compliance with their Noise and Water Resources (drainage requirement). This letter is similar to the letter from the 2017 preliminary approval. The developer will be required to adhere to MnDot’s conditions.

DEVELOPMENT DESIGN STANDARDS A. Intent The use of planned unit developments for regional/lifestyle center commercial purposes should result in a reasonable and verifiable exchange between the city and the developer. This district is intended to provide for the development of regional and community scale integrated retail, office, business services, personal services and services to the traveling public near freeway interchanges. It shall strive to create a self-sustaining pattern of land uses with cultural, employment, entertainment, housing, shopping, and social components. The regional/lifestyle center commercial district is a mixed commercial district with retail and entertainment uses of a scale and function that serves a regional market. The physical environment emphasizes an attractive, comfortable walking experience for shoppers and visitors. It shall be designed to serve pedestrian and mass transit users as well as automobile traffic. Centers of this type, generally, have at least two major retail anchors and are characterized by the diversity of mixed retail and service uses. Uses within this district should complement existing retail users in the other commercial districts. Development of these centers shall be planned as a group of organized uses and structures to accommodate a sensitive transition between commercial activities such as loading, parking of Page | 3 automobiles, lighting and trash collection, and surrounding residential uses. Such centers shall be designed with one theme, similar architectural style, similar exterior building materials, and a coordinated landscaping theme, but shall avoid monotony in design and visual appearance. Vehicle and pedestrian access is coordinated and logically linked to provide a comprehensive circulation system. B. Design Standards Unless otherwise provided in the PUD, the design standards shall follow the Chanhassen City Code Chapter 20, Article VIII Division 1. 20-509. - STANDARDS AND GUIDELINES FOR REGIONAL/LIFESTYLE CENTER COMMERCIAL PLANNED UNIT DEVELOPMENTS and Article XXIII, DIVISION 7. - DESIGN STANDARDS FOR COMMERCIAL, INDUSTRIAL AND OFFICE-INSTITUTIONAL DEVELOPMENTS. Applies to District 1, 2 and 3. Chapter 20 DIVISION 9. - DESIGN STANDARDS FOR MULTIFAMILY DEVELOPMENTS and the Avienda Development Design Guidelines. Applies to Districts 4 and 5. The Master Plan identifies five distinct districts within Avienda. Each of these districts (outlined on the plan below) is defined by specific site development patterns and perhaps a Page | 4 distinctive character or image. The sub-districts complement one another as part of the overall plan. The districts are shown on the attached District Map above. They include: • District 1 - Retail – provides a location for larger-scale in-line and stand-alone retail entertainment uses. • District 2 - The Village – provides the broadest variety, highest density and greatest intensity of development, encouraging both vertical and horizontal mixed use. • District 3 - Mixed Use – provides a location for smaller-scale retail. Serve and auto-oriented uses as well as hotels and medical/technology-related offices. • Sub-District 4 - Multi-Family – provides opportunities for high density senior or rental apartments. • Sub-District 5 - Low Density Residential – provides opportunities for small lot homes.

As a reminder, the City Council approved the following on July 10, 2017: • Preliminary plat • Rezoning to PUD • Conditional use permit • Wetland alteration permit Level 7 Development has made strides to solve for the condition of approval for the project, secure financing and user interest, and prepare the project for grading and infrastructure improvements, but the economy and demand for specific uses have changed. Complicating these changes are the changing demand in the retail industry for bricks and mortar spaces along with the impacts of the COVID-19 pandemic, resulting in the ownership group’s desire to propose minor site plan changes. This will help prepare the site for Phase 1 land development. To be clear, although the ownership is seeking new approvals, the commitment to a high-quality regional lifestyle center remain steadfast. This narrative outlines the major changes to our updated plans and visions for the project and seek approval for the amendment back in front of the Planning Commission and City Council in June / July 2020. SITE PLAN Level 7 Development continues to work with the City to develop a plan that fulfills the City’s vision of a high- quality regional Lifestyle Center while creating flexibility to meet the demands of the current marketplace. A Lifestyle Center creates an experience that goes beyond the traditional retail shopping experience by creating a sense of place with activity generators throughout that draws the community throughout the week for multi-purposes, not just for typical shopping trips. The project will provide opportunities for Chanhassen residents that are not currently available in the city and also draw people from the region to the city. Our plan includes a mix of high-quality detached villa homes, multi-family and senior living residential facilities, office, medical and professional services, retail, entertainment, restaurants, and hospitality. This combination of uses promotes a live, work, and play theme that will be desirable for Chanhassen and surrounding communities. Since our previous approvals, the site plan has been modified to locate the key retail activity center all within the north and central portions of the site. Residential and the office uses are strategically situated around the perimeter of the site to provide a softer transition to the adjacent residential uses. In addition, after we received feedback from retail users and in an effort to create a more pedestrian oriented retail experience, the new site plan eliminates the ring road concept in the northeast area, resulting in less public PUD Amendment Narrative May 1, 2020 3 infrastructure for the City to maintain. This also allows the project to maximize pedestrian con nectivity between the residential and retail uses, while providing for more cross -parking utility and capacity. The other key backbone infrastructure, specifically Bluff Creek B oulevard and Avienda Parkway remain intact as previously approved, providing the City with better connectivity to the neighborhoods west of Avienda. Within the retail area and into the transition area to the residential uses, Level 7 has added a “Village Green” concept that will continue to be developed as the project progresses but is envisioned to become a privately owned public outdoor gathering area for the patrons of Avienda and the public. Programming of the Village Green could range from passive landscaped uses, casual gathering or seat ing areas, or all the way to a fully activated and programmed space for outdoor fitness, a farmer’s market, music venue, or other community-based events. As this area begins to develop and users are identified, Level 7 will bring back specific design and programming proposals as part of the site plan review for this area. The final key change is the relocation of the office uses to the southeast area of Avienda, which can be developed into multiple office users and buildings or provide an opportunity for a larger scale corporate headquarters office user. Through placing the office buildings in this area, structured parking within the buildings can be efficiently designed by using the site grade change and thus resulting in the removal of the large retaining wall that was previously required for the retail uses. These office buildings are planned to be 3-4 story buildings and shown as 75,000 sf per building, resulting in a total of 225,000 sf of planned office space. Overall, the new amended PUD and planned uses results in a net reduction of approximately 170,000 sf of commercial uses from the 2017 approvals, including a net reduction of 100,000 sf of retail space, which aligns with the nationwide trends as the market demand as bricks and mortar retail is reducing. The preliminary plat showed 18 lots and three outlots. The three outlots were proposed as permanent open space. Ownership continues its plans to preserve approximately 20 acres in the southwest bluff area in a conservation easement as previously agreed. Phasing This project will be phased over time with a series of final plats to support the phased development project. All public streets will be platted with the initial plat and future phases will be platted in response to market demand. Level 7 Development is finalizing plans and securing the necessary financing to commence the Phase I work over the next 18 months, which will plat the public right-of-way and will allow mass grading and construction of all new public streets and trunk public utilities infrastructure, specifically the Bluff Creek Boulevard and Avienda Parkway connections Currently, plans for Phase II will begin with the residential areas in the western areas of the site, as these uses are in high demand. Future phases will be added and PUD Amendment Narrative May 1, 2020 4 details will be finalized as part of the site plan and final plat process to ensure consistency with the design vision for Avienda. Bluff Creek Overlay District The Council approved a conditional use permit to impact Bluff Creek Overlay District (BCOD) primary and secondary zone for construction of Bluff Creek Boulevard. The remaining approximately 20 -acres of the BOCD will be placed in a conservation easement. Stormwater Management The plans were designed to maintain the ex isting drainage patterns. Stormwater improvements to serve the proposed development scenarios have been designed to and will be constructed to meet the requirements of the SWMP, RPBCWD rules, and National Pollutant Discharge Elimination System (NPDES) Phase II storm water requirements for the site as a whole. The applicant has been working with city staff on the final designs for the initial infrastructure phase. The project has previously received approvals from Riley Purgatory Bluff Creek Watershed District on its stormwater permit. As part of our PUD amendment, the team has also provided RPCWD with its new plans, and will gain approvals concurrently. Wetlands – Wetland Alteration Permit A wetland delineation was completed with the original approvals for the property and the LGU (City of Chanhassen) concurred with the delineation. Wetlands 3, 4, 6 and 10 will be preserved and will comply with the wetland buffer requirements. The ownership group has previously purchased the wetland bank credits for the wetlands that could not be reasonably saved or mitigated. PUD AMENDMENT The major site plan modifications have been described in previous sections. In addition, attached to this application is the Avienda Design Guidelines, which establish the design parameters for the project to create a consistent design theme for future owners and users of the project. These guidelines will be used to describe design preferences, illustrate design intent, and set the framework for review of future site plan and architectural reviews. The guidelines are not intended to be a prescribed solution but promote creative design options for the variety of uses throughout Avienda. Some of the key components of the Design Guidelines are: - Streetscape - Parking - Architecture PUD Amendment Narrative May 1, 2020 5 - Signage (building and site) - Public spaces While each use within Avienda has different design and operational requirements, the Design Guidelines tailor the design approach in each district, while providing a consistent theme throughout the project. The district areas are shown below in the graphic and further definitions of our appro ach can be found in the Design Guidelines: Finally, the Phase I plat will simply be to allow construction of the public infrastructure and complete mass grading to the allow those improvements. Future phases and plats will be brought before the planning commission and City Council for approval as projects begin to develop. SCHEDULE Level 7 Development’s had full intention to begin grading and constructing public infrastructure this summer, but as we all have been impacted by the pandemic, so has the potential end users. Level 7 already owns the property and with your approval of this PUD Amendment, it allows the flexibility to move forward with the project into Phase 1, either in late summer / fall 2020 or early spring 2021. The key dates are as follows and we ask for the Council’s help to keep the project moving so that we can break ground yet this year: 1. City Submittal for Phase 1 preliminary plat (public infrastructure and grading) a. Submit to the City – May 1 b. Planning Commission – June 6, 2020 PUD Amendment Narrative May 1, 2020 6 c. City Council approval – July 13, 2020 2. Final Plat Submittal for Phase 1 a. Submit to City – August 12, 2020 b. Planning Commission – September 15, 2020 c. City Council Approval – September 28, 2020 3. Anticipated City Submittal for Phase II plat, site plan a. Submit to City – June 15, 2021 b. Planning Commission – July 2021 c. City Council Approval - August 2021 SUMMARY We look forward to providing an update to the Council at the June 22nd Work Session and look forward to continued Council support for Avienda at the Council meeting on July 13th.

Restricted access to storage areas must be provided to prevent vandalism. Storage and disposal ofhazardous waste or materials must be in compliance with Minn. R. Ch. 7045 including secondary containment as applicable.Portable toilets must be positioned so that they are secure and will not be tipped or knocked over.Concrete and other washout waste: operator must provide effective containment for all liquid and solid wastes generated by washoutoperations. The liquid and solid wastes must not contact the ground, and the containment must be designed so that it does not resultin runoff from the washout operations or areas. Liquid and solid wastes must be disposed of properly and in compliance with MPCArules. A sign must be installed adjacent to each washout facility that requires site personnel to utilize the proper facilities for disposalof concrete and other washout wastes.External vehicle washing: external washing of trucks and other construction vehicles must be limited to a defined area of the site.Runoff must be contained and waste properly disposed of. No engine degreasing is allowed on site.Operator shall take reasonable steps to prevent the discharge of spilled or leaked chemicals, including fuel, from any area wherethey will be loaded or unloaded as detailed in the Permit.INSPECTIONS AND MAINTENANCE1.2.3.4.5.6.7.8.9.10.11.See Grading, Drainage, and Erosion Control sheets for the location and type of temporary erosion prevention and sediment controlBMPs. See Grading, Drainage, and Erosion Control sheets for the location and type of permanent erosion prevention and sedimentcontrol BMPs.Minimize Disturbed Areas and Protect Natural Features and SoilAppropriate construction practices (e.g. construction phasing, vegetative buffer strips, horizontal slope grading) shall be used tominimize erosion.Areas not to be disturbed (buffers, bluff creek overlay districts, etc.) shall be protected with construction or silt fence before workbegins.Operator shall develop methods to minimize soil compaction outside of building pads, pavement areas and utility trenches and shalluse tracked equipment wherever practicable.Topsoil shall be salvaged and reused to the extent practicable.Phase Construction ActivityOperator must not disturb more land than can be effectively inspected and maintained.Sediment control practices shall be established on all down gradient perimeters before any upgradient land disturbing activities begin.These practices shall remain in place until final stabilization has been established in accordance with the Permit.The timing of the installation of sediment control practices may be adjusted to accommodate short-term activities such as clearing orgrubbing, or passage of vehicles. Any short-term activity must be completed as quickly as possible and the sediment controlpractices shall be installed immediately after the activity is completed. However, sediment control practices shall be installed beforethe next precipitation event even if the activity is not complete.Control Stormwater Flowing onto and Through the ProjectThe normal wetted perimeter of any temporary or permanent drainage ditch or swale that drains water from any portion of theconstruction site, or diverts water around the site, shall be stabilized within 200 lineal feet from the property edge, or from the point ofdischarge into any surface water.Stabilization of the last 200 lineal feet shall be completed within 24 hours after connecting to a surface water.Stabilization of the remaining portions of any temporary or permanent ditches or swales shall be complete within 14 days afterconnecting to a surface water and construction in that portion of the ditch has temporarily or permanently ceased.Temporary or permanent ditches or swales that are being used as a sediment containment system (with properly designed rock ditchchecks, bio rolls, silt dikes etc.) do not need to be stabilized. These areas shall be stabilized within 24 hours after no longer beingused as a sediment containment system.Stabilize SoilsAll exposed soil areas, including stockpiles, must be stabilized. The site has discharge points within one mile of, and flows to impairedwaters. Therefore, stabilization of all exposed soil areas shall be initiated immediately to limit soil erosion in that portion of the sitewhere construction has temporarily or permanently ceased. Stabilization must be completed with in seven (7) calendar days ofcessation of construction activity.Temporary soil stockpiles shall have silt fence or other effective sediment controls, and cannot be placed in surface waters, includingstorm water conveyances such as curb and gutter systems, or conduits and ditches unless there is a bypass in place for the stormwater.Temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition concretestockpiles, sand stockpiles) and the constructed base components of roads, parking lots and similar surfaces are exempt from thisrequirement.Protect SlopesOperator shall avoid work on slopes with a grade of 3h:1v or greater when practicable. Grading on slopes with a grade of 3h:1v orsteeper will require techniques such as phasing and stabilization practices designed for steep slopes (e.g., slope draining andterracing).Protect Storm Drain InletsAll storm drain inlets shall be protected by appropriate BMPs during construction until all sources with potential for discharging to theinlet have been stabilized. Inlet protection may be temporarily removed if a specific safety concern has been identified.Provide Energy Dissipation at all Pipe Outlets Within 24 HoursAfter connection to a surface water or permanent stormwater treatment system.Establish Perimeter Controls and Sediment BarriersPrior to disturbing soils on a project site, establish sediment control BMPs on all downgradient perimeters and where site dischargesto public waters.Retain Sediment On-site and Control Dewatering PracticesDewatering or basin draining of turbid or sediment laden water related to construction activities shall be discharged to a temporary orpermanent sedimentation basin or treated with the appropriate BMP prior to entering the surface water.Discharge shall not cause nuisance conditions, erosion in receiving channels, adversely affect receiving water or impact wetlands, ordownstream properties. Discharge points shall be adequately protected from erosion and scour by accepted energy dissipationmeasures.Discharge water containing oil or grease shall be treated to remove oil or grease prior to discharge to surface waters.Refer to Permit requirements for temporary or permanent sediment basins.Establish Stabilized Construction ExitsVehicle tracking pads shall be established as shown on the grading, drainage, paving and erosion control sheet to minimize trackingof sediment from the construction site onto adjacent streets.Infiltration Basin ProtectionOperator must not excavate infiltration systems to final grade or within three (3) feet of final grade until the contributing drainage areahas been constructed and fully stabilized unless rigorous erosion prevention and sediment controls have been installed.When excavating an infiltration system to within three (3) feet of final grade, operator shall mark off and protect the area from heavyconstruction equipment to prevent compaction of soils.Dewatering and Basin DrainingPermittees must discharge turbid or sediment-laden waters related to dewatering or basin draining to a temporary or permanentsediment basin. Discharges must not cause erosion or scour near the discharge points.Remove Sediment from Surface WatersAll sediment deposits and deltas must be removed from surface waters (including drainage ways, catch basins, and other drainagesystems) and the removal areas restabilized within seven (7) days.1.2.3.4.5.6.7.8.9.10.11.12.13.14.RECORD KEEPING / RECORD RETENTIONThe SWPPP (original or copies) including, all changes to it, and inspections and maintenance records shall be kept at the site duringconstruction by the Owner / Operator who has operational control of that portion of the site.

They serve as a framework within which creative design can and should occur. There is no one prescribed solution, but many options that can meet the basic requirements and intent of this document. Application The format and content of these guidelines are specifically tailored for use as a reference workbook that is organized into two parts. The first part outlines issues and recommendations that apply to the entire project area. The second section highlights specific guidelines that apply to each sub-district. Implied Responsibility All participants in the development of this project area must recognize the local and community impacts of this project and the various systems that play an important role. Each building must fit within the context of the entire plan. Individual projects must complement, not compete with, adjacent development in terms of public space, walk and trail connections, stormwater management solutions, street layout, parking strategies, land use mix and building design. Projects in this development will also need to comply with City of Chanhassen planned unit development (PUD) standards. Overview Avienda (Pronounced: Ah-vee-EN-da) is a district with “elegant vitality”, fulfilling the City of Chanhassen’s vision to become one of the region’s most vibrant, prosperous communities. Located at the confluence of Highway 212 and Powers Boulevard, Avienda offers a desirable, diverse shopping and lifestyle destination with convenient access. As a gateway to the City of Chanhassen, development in Avienda should blend the best of residential, retail, office, medical and hospitality. It should support high quality, attractive design that is compatible as a whole with forms and materials that are authentic to the region. Design Drivers • Timeless architectural features and forms • A color palette drawn from earth tones and natural elements • A safe, balanced network of pedestrian, bicycle and automobile access • Inclusive opportunities to relax and gather • Lush, resilient plantings with multi-season interest • Responsible resource use Introduction To Design Guidelines This document is intended to help direct design solutions and define character for this project. It is also intended to provide concepts for future development that will establish and maintain the aesthetic character of Avienda. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 7 Part One: Overall Overview There are a number of standards that apply to the entire Avienda development including recommendations for stormwater management, parks, streets, land use, parking, transit and other development components. Many of these overall Avienda guidelines overlap, or are integrated with one another. For ease of discussion they are categorized according to the same list of “layers” that formed the basic structure for the Guidelines: • Context – local, city, regional • Street Hierarchy – access, circulation, arrangement • Streetscape – preferred design, location • Parking – quantity, location, type • Architecture – preferred uses, horizontal/vertical mixed use, built form, character of development • Signage – design, location, quantity, type • Stormwater Management – surface water features, stormwater management • Open Spaces – trails and plazas It is essential that proposed design solutions for development projects and other improvements within Avienda demonstrate an understanding of the interplay between these layers. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 8 Context Overview Avienda is a unique area within Chanhassen; but it is a part of, and connected with, a variety of local, city-wide and regional systems (See Figure 1). Each development project, whether a single building, one lot, or a series of blocks, must provide reasonable links to these systems as a primary design objective. Recommendations To ensure that Avienda takes full advantage of local and regional systems, development should: • Provide safe, easily-recognized connections to city, county and state trail corridors • Make provisions for public amenities and encourage their use • Tie into, and improve, the Chanhassen utility network • Integrate with and complement the existing (and future) street framework • Become an integral part of the city and county drainage/stormwater management plan Objectives • Stormwater shall be managed to the maximum extent practicable to meet the requirements of the watershed, city and other agencies. Where stormwater features are visible, they should support the aesthetic design of the development • Bikeways and pedestrian routes in Avienda must be designed for safety and ease of access. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 9 Street Hierarchy Overview The Development Master Plan defines a strategy for the layout of public and private streets in Avienda. The size, type and configuration of this street hierarchy is based on a combination of projected traffic volume, level of service at intersections, proposed adjacent land use and desired aesthetic character. These guidelines promote a system that balances pedestrian and vehicular use. Recommendations The proposed street pattern reflects an opportunity for residents and visitors to park once and enjoy the shops and amenities on foot. Methods to achieve this include: • Provide a street network that distributes pedestrian and vehicular traffic throughout Avienda (many choices or travel paths) • Promote improvements that invite pedestrian and bicycle use including wide sidewalks, streetscape amenities and designated bicycle trails DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 10 Conceptual Roadway LightingConceptual Pedestrian Lighting Objectives Creative design solutions for streetscape improvements should include: • Streetscape improvements that provide traffic calming • Inviting streetscapes that balance the needs of automobiles and pedestrians, and draw you into and through Avienda • A marriage of building design and streetscape design that encourages active spaces near the streets Street Lights Decorative street lights are desired for Avienda and the developer will work with the City and Xcel Energy to finalize the luminaire and pole types. Lighting design: Conceptual Roadway Lighting - Traditional Style Lamp in Bronze, offered through Xcel Energy, has been chosen for its aesthetic coordination with existing street fixtures in the neighborhood. Conceptual Pedestrian Lighting - BEGA brand 84 483 K3 (pole top luminaires) has been chosen for its quality and aesthetic. Select a style of similar character and quality. Streetscape Overview Amenities within the public right-of-way – and private portions of the pedestrian realm – play an important role in the aesthetics and placemaking of the Avienda streetscape: • Plazas and public gathering spaces • Street/sidewalk character and streetscape elements • Pedestrian/bicycle connections • Residential courts and other private green space The goal is to foster a safe and welcoming public realm that will invite pedestrian activity, promote traffic calming and encourage community gathering. Street trees, lighting and decorative fencing frame corridors and outdoor rooms. Special pavements, street furniture, public art and layered plantings will enhance points of interest and transition. Recommendations Give pedestrian scale to otherwise vast open parking lots, streets and plazas by: • Incorporating boulevard, median, and parking island trees to frame space and provide shade • Installing street lighting that meets all safety standards and design criteria, while creating a signature character for this district • Providing bike parking and pedestrian connections as part of each project within Avienda • Placing benches, seating, wayfinding kiosks and litter receptacles with regularity along trail loops DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 11 SidewalkBoulevard Median Street Street Boulevard TrailBirds eye of Bluff Creek Boulevard Section STREETSCAPE CHARACTERISTICS CHARACTER Natural Urban MAINTENANCE Low High PLANTING DENSITY High (screening) Low (visibility) PRIMARY USERS Automobile Long Term Impact SITE PRIORITY Immediate Impact Pedestrian Landscape enhancements at intersections Consistently planted median with thematic tie-ins to Avienda brand Swamp White Oak River Birch Street Trees Red Oak Northwood MapleDiscovery Elm White Oak DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 12 Lush plantings with year round interest and low water use. Avienda District Map Comfortable pedestrian connections within parking lots. Screen loading areas with high-quality materials that are consistent with the principal building. Parking Overview Balancing the realities of auto-related necessities and the desired character of Avienda is a significant challenge. The goal is to provide adequate parking – both quantity and location – while promoting new strategies that support the overall needs of Avienda. Parking will be provided through a combination of on-street spaces, off-street surface lots and structured ramps to support the mix of uses at Avienda. Parking structures should be below ground in high-density residential buildings or be lined with store/units or other street-level uses that are integrated into ramp design. Recommendations Parking guidelines encourage the following: • Provide a combination of fencing and landscaping to minimize the prominence of parking areas from important views • Explore options to integrate stormwater management requirements into parking area design • Landscaped parking islands intended for tree plantings must include adequate soil volume for healthy tree growth. Generally, provide one to three cubic feet of soil volume per one square foot of tree canopy area Objectives The primary objective is to provide a balance of surface lots, on-street and structured parking, with ample quantities and close proximity to serve the mix of uses in Avienda. In addition to providing adequate space, quality design is crucial. The framework for Avienda encourages creativity, innovation, quality and attention to detail in the project development, including parking solutions. Minimum Standards Parking in Avienda is intended to be shared to the greatest extent practicable in all mixed-use areas. Parking shall be provided under any of the following arrangements: • Shared parking arrangements between nearby uses are encouraged in all districts, including across Districts 1 and 2 • Within District 2 parking on individual parcels serving individual uses may be provided if designated and approved as part of the master plan • The development team will work with the City to identify opportunities for reduced and shared parking throughout the project Loading Areas Loading areas and docks shall be placed on the building’s least visible elevation. Loading areas shall be screened from public streets and residential areas through landscaping and building design measures. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 13 Architecture Overview The architectural guidelines are intended to encourage an integration of both traditional and contemporary design. Buildings should have a balanced horizontal/vertical rhythm of windows, offsets, roof lines, materials and entrances. Buildings should be highlighted by massing variety that includes transition lines. Main entrances of buildings should be clearly identifiable and timeless architectural materials, features and forms should be integrated into the design. Architectural designs should provide high-quality design, measured, to a great degree, by the pedestrian experience along the street and sidewalk and by an architectural expression that provides character without being obtrusive or artificial. The quality of the materials selected shall be guided by the design drivers and classified in the Material Classification table. Recommendations Of all the layers that combine to form the project master plan, architecture will typically be the most prominent development component. Both visually and physically, architecture will play a major role in defining the overall design character and mix of uses. It is crucial that the design and location of buildings address these architectural guidelines with specific emphasis on the following: • Promote an animated street presence with a mix of street-level uses, interesting building facades, doors and windows on the street where appropriate, careful design of lighting, awnings, signage and other elements that animate the pedestrian experience • Promote variety in building design, character and expression; not one theme or building style, but a thoughtful integration of many design solutions • Promote a variety of building types, including a range of height, scale and proportion that supports an integrated mix of shopping destinations, food venues, service businesses, commercial office options and other mixed uses • Building location is as important as building style; special architectural elements, character, transparency and a higher level of materials and detailing should be used to highlight corridors and crossroads throughout the project • Encourage the use of high-quality materials (as listed under the material classifications), suggesting a preference toward native materials, with respect for local building techniques • Minimize the impact of all mechanical equipment, as viewed from ground levels at a variety of locations. All mechanical equipment located on the roof or around the perimeter of a structure shall be screened natural stonestucco/eifs greenscreen -steel structure and “greenscreen” mesh infill creates living scrim walls of vines storefront system -clear anodized aluminum storefront system with green tinted glass and spandrel glass -copper roof and facade panels copper metal panels steel structure and angled louvers create filtered shade shade trellis Material Classification* Class I: • Brick • Natural stone • Glass • Copper metal panels • Specialty concrete • Architecturally precast textured concrete panels Class II: • Opaque panels • Ornamental metal • Architectural rockface cmu • Masonry stucco • Exterior insulating finishing system (EIFS) • Wood *Other comparable or superior materials may be approved by Design Review Committee (DRC) by a raised parapet, by comparable and compatible exterior building materials, or painted to complement the building materials in order to diminish its impact. Incidental rooftop equipment deemed unnecessary to be screened by the City shall be of color to match the roof or the sky, whichever is more effective. • Equipment used for mechanical, processing, bulk storage tanks, or equipment used for suppressing noise, odors and the like that protrudes from a side of a building or is located on the ground adjacent to a building shall be screened from public view as much as practical with materials matching the design of the building. Where miscellaneous exterior equipment cannot be fully screened with matching building materials, landscaping may be used as additional screening. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 14 Sign Master Plan Signage Overview Signage within Avienda should provide a system for clear wayfinding for all modes of transportation and should ensure successful business operation while maintaining Avienda’s brand. The Master Sign Plan identifies key sign locations. Developments shall apply to the City of Chanhassen for sign permitting. Objectives Signage should be used as a tool to help identify businesses and neighborhoods within Avienda and should have elements that are focused on its pedestrian nature as well as the signage needs for businesses. Signage and lighting which is integrated into the design of the building is encouraged. Definitions Project Identification Sign means a permanent ground, low profile sign which identifies a specific residential, industrial, commercial or office development and which is located on the premises of the development which it identifies. Off-Premise Directory Sign means a sign which identifies the names of specific businesses located in a shopping center, medical center or commercial, industrial or office development project which is located on the premises or entrance of the center or development so identified. Monument Sign means a low profile sign to identify key tenants on the parcel upon which the sign is located. Wayfinding Sign means a sign containing descriptions of major points of interest and businesses. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 15 Project Identification Sign with Off-Premise Directory Sign in background Off-Premise Directory Sign Wayfinding Signage Off-Premise Directory Sign The Off-Premise Directory Sign is allowed as part of a holistic design coordinated with the Project Identification Signs at the Powers and Lyman entrances locations. The sign shall coordinate with the materials of other signage on site. Tenant sign panel may be 8 sf, 6’-0” wide x 1’-4” tall, up to (3) three signs per monument. Wayfinding Signs The pedestrian-oriented nature of Avienda requires unique signage that will build on the design concepts for the development. These types of signs include street signs and wayfinding signs. Such signage shall be allowed on public spaces as needed to provide information and wayfinding. Standards Project Identification Sign Project Identification Signs are located at the following locations as shown on the Sign Master Plan: • Two at the Powers Boulevard entrance • One at the Lyman Boulevard entrance • One at the retaining wall facing Highway 212 • One at the corner of Lyman Boulevard and Powers Boulevard • One at the intersection of Bluff Creek Boulevard and Avienda Parkway These signs located around the periphery of the Avienda development are allowed as shown on the signage plan and shall have consistent materials and colors. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 16 Below and Right: Natural stone materials are preferred for sign bases of all scales Above: Monument Sign with multiple tenants Avienda District Map Project Identification Sign, view from highway 212 Monument Sign One sign is allowed per building in Districts 1-5 provided that the following standards are met: • The signboard shall be constructed of wood, acrylic, aluminum or metal and shall be architecturally compatible with the style, composition, materials, colors and details of the building • No part of the sign shall encroach on the right-of-way and its location shall not interfere with pedestrian or vehicular circulation • Projects with multiple tenants in a single building shall coordinate project signage as part of a holistic design. Monument signs within District 2 should incorporate the Village brand identity of Avienda. Prohibited signs The following signs are prohibited: • Signs employing mercury vapor, low pressure and high pressure sodium and metal halide lighting; plastic panel rear-lighted signs. • Signs on roofs, dormers and balconies • Billboards • Back-lit awnings • Interchangeable letter boards or panels • Flashing signs DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 17 Building Signs The following parameters apply to building signs. Local authority review, approval and permitting are also required. All storefront signage and graphics are to be first reviewed and approved. All sign packages are to include: • Locations • Sizes • Style of lettering • Materials • Types of illumination • Installation details • Logo design No roof-mounted signs are permitted. Store identification signs shall be limited to the Purchaser/Lessee’s trade name. The Purchaser/Lessee must use a crest, shield, logo or other establishment corporate insignia, the area of which shall be included within the allowable sign area. Any sign, notice or other self-illuminated signs, located in the interior of the premises and easily legible from the exterior, except those which are required by law, code, ordinances or regulations, will be allowed only if permitted by the City of Chanhassen. All attachment devices, wiring, clips, transformers, lamps, tubes, bulbs, light sources, manufacturers labels and plates and other mechanisms for signage shall be concealed from public view. Letters may be interior-illuminated with lamps wholly within the depth of the letter. Only the following types of storefront signage will be permitted: • Individual dimensional work or metal back-lit (“halo effect”) letters. • Internally-illuminated channel letters with opaque metal sides and translucent plastic faces. • No exposed crossover, raceways, ballast boxes or transformers will be permitted for wall-mounted signs. Raceways needed to support otherwise floating letters (not mounted to a wall) shall be painted to match adjacent buildings. All penetrations of the building structure required for sign installation shall be seating in a water tight condition and shall be patched to match adjacent finish. The following types of signs and sign components and devises will not be permitted unless otherwise approved: • Moving, rotating, or revolving signs • Exterior changeable letters or signs • Noisemaking signs • Signs painted directly on the storefront sign band • Signs employing flashing, flickering, changing or moving lights of any kind • Inflatable signs Examples of some features that align with this intent are shown at right. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 18 Large Tenant Retail Signage Large Tenant Retail Signage • Calculations apply to tenants with more than 10,000 sf of leasable area • Signage shall be integrated into the architectural features of the façade to which they are attached • Maximum signage area is calculated at 15% of wall area for each building • Maximum area calculation may transfer to other storefronts, leased by the same tenant to increase tenant visibility to surrounding streets • Wall-mounted signs shall not project more than 10” from the building. Cabinet signs are prohibited. • Service/secondary signage maximum area is 2 sf Table 1 Max.

The mix of systems will provide an environmentally responsible, visually pleasing strategy to manage stormwater while providing focal amenities. Detailed strategies for managing stormwater within Avienda can be found in the Stormwater Management Plan. Objectives • Stormwater shall be managed to the maximum extent practicable to meet the requirements of the watershed, city and other agencies. • Integration of water and landscape, use of high quality materials and providing a safe environment supply the overlying objectives. Recommendations Stormwater management facilities will be for the most part installed and maintained by the master developer. Individual development projects should implement additional management features, as feasible, depending on their specific situations. DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 20 Public Spaces Overview Avienda healthy living brand seeks to incorporate a full menu of activity choices for visitors and residents. The plan links the existing neighborhood and trails through Avienda, creating interesting gathering nodes along the way. Of equal importance is the contribution from each development project to this network of green, adding a variety of private, semi-private, and perhaps some additional public space throughout Avienda. Private development will share the responsibility to provide inviting, innovative and usable green space as integral parts of individual parcel site design. Recommendations The Design Guidelines encourages the following: • Private development should provide inviting gathering space as integral parts of each development project • Create signature features (ponds, fountains, plazas) as major visual amenities throughout Avienda • Small pedestrian nodes should highlight transition points within Avienda and provide respite along particularly long stretches of trail Objectives Based on the Development Master Plan for Avienda, a variety of public and private green space is proposed including: • Each project within Sub-Districts 1, 2, 3 and 4 will provide intentional plazas or green areas as integral components of site development and building design • A pedestrian node should include seating, a litter receptacle and shade with proportional understory plantings to anchor the area comfortably within the context of the trail or sidewalk. Pedestrian level lighting and wayfinding should be considered depending on the node location PEDESTRIAN NODE CHARACTERISTICS CHARACTER Natural Urban MAINTENANCE Low High PLANTING DENSITY High (screening) Low (visibility) PRIMARY USERS Pedestrian Automobile Long Term Impact SITE PRIORITY Immediate Impact Views of plantings and pedestrian nodes along primary pedestrian routes Avienda District Map DEVELOPMENT DESIGN GUIDELINES Avienda Overall – 21 Pedestrian Circulation Model Swamp White Oak Pink Spires Crabapple Red Jewel Crabapple Red OakRiver Birch Northwood MapleDiscovery Elm Street Trees Pedestrian Interest Eastern White Pine Crimson Spire Oak Sub-Districts – 22DEVELOPMENT DESIGN GUIDELINES Part Two: District Guidelines Overview The Master Plan identifies five distinct districts within Avienda. Each of these districts (outlined on the plan below) is defined by specific site development patterns and perhaps a distinctive character or image. The districts complement one another as part of the overall plan. The districts are shown the attached District Map (Figure 5). They include: • District 1 - Retail – provides a location for larger-scale in-line and stand- alone retail and entertainment uses. • District 2 - Village Retail – provides the broadest variety, highest density and greatest intensity of development, encouraging both vertical and horizontal mixed use • District 3 - Mixed Use – provides a location for smaller-scale retail, service and other auto-oriented uses as well as hotels and medical/technology- related office. • District 4 - Multi-Family Housing – provides opportunities for high density senior or rental apartments • District 5 - Low Density Housing – provides opportunities for small lot homes Development plans must respond to the overall Avienda Design Guidelines described in Part One, but also the following detailed framework for each sub- district. To further clarify and illustrate proposed features in the Master Plan, these sub-district guidelines are organized under the following categories: • Public Realm / Streetscape • Site Design • Architectural In all cases, the sub-district framework must be applied in harmony with the overall Avienda framework and with other existing city, county, state codes, design criteria, plans and studies that support broader goals for regional growth and development. Public Realm/Streetscape The developer shall be responsible for construction of all streetscape improvements along adjacent streets. These improvements include all hardscape and landscape improvements, such as trails, sidewalks, street trees, benches, bike racks, litter receptacles and plantings. Plazas Except for District 5-Low Density Housing, all properties with principal buildings should have some public plaza space. The public plaza space should include benches, trash receptacles, lighting fixtures and other amenities to create a welcoming space for tenants, residents and guests. These plazas spaces should be visible from the main site access (front door) or well aligned with the project’s public frontage. MIXED USE DISTRICT VILLAGE RETAIL DISTRICT RETAIL DISTRICT MULTI-FAMILY HOUSING DISTRICT MULTI-FAMILY HOUSING DISTRICT LOW DENSITY HOUSING DISTRICT Sub-Districts – 23DEVELOPMENT DESIGN GUIDELINES BUILDING CHARACTER Providing a creative mix of building types, scales and expressions ARCHITECTURAL EXPRESSION contemporary “timeless” design that translates to all aspects of the development Sub-District 1 – 24DEVELOPMENT DESIGN GUIDELINES District 1 - Retail Public Realm/Streetscape The Retail District encourages a mix of large and small floor plate buildings comprised of retail and entertainment uses. With opportunities for in-line retail development comes auto-related infrastructure such as easily accessed surface parking lots. Again, this suggests that equal attention be paid to public realm and streetscape improvements that not only accommodate vehicles, but also invite bicycle and pedestrian traffic through surface parking areas. Site Development Buildings in this district should orient towards surface parking, with primary entries provided to animate these façades. Architectural Character Massing and rhythm define the overall feel of an individual building. Massing and rhythm in this district should include breaks in the roof line and vertical transition lines that articulate separate tenants in the same building. Massing and rhythm should continue around corners and buildings should not appear to have a “rear” facade. Maximum heights for buildings in this sub-district are limited to three stories. Sub-District 2 – 25DEVELOPMENT DESIGN GUIDELINES District 2 - Village Retail Public Realm / Streetscape Public realm and streetscape improvements define the character of Avienda and create a memorable signature for the Village District. Great plazas and great streets encourage intensified levels of activity, support the proposed mix of uses, invite community gathering and accommodate special events throughout the year. • Provide gracious sidewalk width to support intensity of pedestrian traffic in the Village District • Incorporate durable, high quality amenities including unit pavers, integral-colored concrete or scoring patterns, additional plantings, ornamental fencing and other features • Trees and planters along Village District streets to create an inviting space. • Wide sidewalks and logical connections to the Avienda trail system. Outdoor dining is encouraged • Plaza space is strongly encouraged at key development nodes. A variety of plaza uses have been explored to support the needs of residents and guests to gather, play, relax and eat Architectural Character Buildings should be composed of a visually distinct “base”, “middle” and “top”. Adopting a visually-distinct base will support the relationship of the building to the pedestrian experience. Adopting a visually distinct middle will create locations to provide signage as well as architectural massing and overall proportions that enhance the character of the development. Adopting a visually-distinct top will create consistency and will uniquely identify where the building meets the sky. Heights in this zone are restricted to a maximum of two stories above grade. Village Characteristics CHARACTER Natural Urban MAINTENANCE Low High PLANTING DENSITY High (screening) Low (visibility) PRIMARY USERS Pedestrian Automobile Long Term Impact SITE PRIORITY Immediate Impact Sub-District 2 – 26DEVELOPMENT DESIGN GUIDELINES Corner tenants are allowed to match primary entrance signage at two storefronts. Blade Sign(s) to be calculated as part of total allowable signage. Blade Signs to be a min. of 8’ AFF, may not extend above the cornice line, and may have a max. signage area not to exceed 4 sf per face. Wall-mounted signs shall not project more than 10” from the building. Cabinet signs are prohibited. “Storefront” refers to the first 12’ above each tenant floor of lease area building frontage with public access. “Elevation” refers to the first 12’ above each tenant floor of lease area building frontage without public access. Office tenant signage will be allowed on a building directory near the primary entrance and ability to use monument signage locations. Design Review Committee approval shall be based on sign design quality, attractiveness, scale appropriateness and compatibility with the building to which attached. Service/secondary signage maximum area is 2 sf. Outlots will be allowed (1) freestanding ground monument within their property that conforms to the overall development materials and aesthetic, with a maximum size of 5’-0” (H) x 10’-0” (W) with approval by the Design Review Committee. Signage Village Project Sign areas: Large tenant signage #1, 15 sf, 4’-0” wide x 3’-8” tall, (1) one sign per Project Sign Large tenant signage #2, 8 sf, 4’-0” wide x 2’-0” tall, (2) two signs per Project Sign Village Tenant Signage Criteria: Tenant signage calculations apply to tenants with less than 10,000 sf of leasable area. Maximum signage area is calculated at 15% of storefront area for each elevation of the storefront. Optional signage allowance on rear elevation. Signage to be no more than 50% of primary entrance. Length of the sign shall not be more than 75% of the overall tenant storefront measured linearly in width. Signage may be calculated for each storefront or elevation facing a designated pedestrian corridor. Maximum area calculation may transfer to other storefronts or building elevations leased by the same tenant to increase tenant visibility to surrounding streets. The body of the sign shall not exceed 30” in height. Enlarged initials, capitals and extended typographical elements (e.g., such as the up and down strokes of “g” and “h”, etc.), are acceptable up to a maximum of 36” in height or width. Stacked signage or logos must not exceed 48” in height and must fit other signage criteria. Sub-District 2 – 27DEVELOPMENT DESIGN GUIDELINES Streetscape Character Sub-District 2 – 28DEVELOPMENT DESIGN GUIDELINES Gathering space related to adjacent retail that encourages lingering, gathering and connection. This setting identified as LIVE/RELAX is a peaceful area with small seating groups and options for an overhead canopy, fire feature, kinetic art, calming water features and lush plantings.

These auto-oriented uses suggest even greater attention be paid to public realm and streetscape improvements that not only accommodate vehicles, but also invite pedestrian and bicycle traffic. Surface parking lots provide convenient access to office buildings and storefronts but present an additional challenge to the overall visual character and aesthetic appeal of this area. Plazas adjacent to main entrances are encouraged. Architectural Character Multi-story buildings in the Mixed Use District should have a ground-floor level that is visually distinct and proportionally larger than individual floors above it. Buildings in this district should not appear to have a rear façade, and building heights are restricted to four stories above grade. Sub-District 4 – 38DEVELOPMENT DESIGN GUIDELINES District 4 - Multi-Family Housing Public Realm/Streetscape A large preserve area and access to regional trails supply the informal green space for Avienda, and more specifically, provide the valuable park frontage and mix of amenities needed to support housing development within the Multi- Family District. Site Development The Multi-Family District emphasizes residential development. To support the proposed housing, a well connected project will link residents to the Village Retail District (activity center of Avienda) and adjacent recreational amenities. Residential front doors will connect with public walks along each of these streets promoting the urban character of Avienda. Special attention should be paid to welcome adjacent existing neighborhoods into Avienda. Architectural Guidelines Buildings in the Multi-Family District should have uniformly proportional floors. Architectural expressions on the facade should relate to the units behind and should create a distinct seperation of the individual units in a generally uniform design style. Heights are restricted to six stories above grade. Sub-District 5 – 39DEVELOPMENT DESIGN GUIDELINES District 5 - Low Density Housing Public Realm/Streetscape A large preserve area and access to regional trails supply the informal green space for Avienda, and more specifically, provide the valuable park frontage and mix of amenities needed to support housing development within the Multi- Family and Low Density Districts. Site Development The Low Density District emphasizes residential development. To support the proposed housing, a well connected project will link residents to the Village Retail District (activity center of Avienda) and adjacent recreational amenities. Residential front doors will connect with public walks along each of these streets promoting the urban character of Avienda. Special attention should be paid to welcome adjacent existing neighborhoods into Avienda. • Within this district a minimum driveway length of 20-feet is recommended to limit conflicts between vehicles parked in the driveway and street or sidewalk users Metropolitan District Waters Edge Building 1500 County Road B2 West Roseville, MN 55113 An equal opportunity employer MnDOT Metropolitan District, Waters Edge Building, 1500 County Road B2 West, Roseville, MN 55113 May 20, 2020 Kate Aanenson Community Development Director City of Chanhassen 7700 Market Blvd P.O. Box 147 Chanhassen, MN 55359 SUBJECT: MnDOT Review # P20-029 Avienda Preliminary Plat and PUD Ordinance NW Quad US 212 & Powers Blvd Chanhassen, Carver County Dear Ms. Aanenson: Thank you for the opportunity to review the Avienda Preliminary Plat and PUD Ordinance. MnDOT has reviewed the documents and has the following comments: Noise: MnDOT's policy is to assist local governments in promoting compatibility between land use and highways. Residential uses located adjacent to highways often result in complaints about traffic noise. Traffic noise from this highway could exceed noise standards established by the Minnesota Pollution Control Agency (MPCA), the U.S. Department of Housing and Urban Development, and the U.S. Department of Transportation. Minnesota Rule 7030.0030 states that municipalities having the authority to regulate land use shall take all reasonable measures to prevent the establishment of land use activities, listed in the MPCA's Noise Area Classification (NAC), anywhere that the establishment of the land use would result in immediate violations of established State noise standards. MnDOT policy regarding development adjacent to existing highways prohibits the expenditure of highway funds for noise mitigation measures in such developed areas. The project proposer is required to assess the existing noise situation and take the action deemed necessary to minimize the impact to the proposed development from any highway noise. If you have any questions regarding MnDOT's noise policy please contact Natalie Ries in Metro District’s Noise and Air Quality Unit at 651-234-7681 or Natalie.Ries@state.mn.us. Water Resources: A Drainage Permit is required for any development that discharges stormwater to MnDOT right- of-way/drainage system. The permit applicant shall demonstrate that offsite runoff coming to MnDOT Metropolitan District, Waters Edge Building, 1500 County Road B2 West, Roseville, MN 55113 MnDOT drainage system and/or right-of-way will not increase as a result of the proposed project. The drainage permit application, including the information below, should be submitted online to: https://dotapp7.dot.state.mn.us/OLPA The following information must be submitted with the drainage permit application: 1) A grading plan showing existing and proposed contours. 2) Drainage area maps for the proposed project showing existing and proposed drainage areas. Any off-site areas that drain to the project area should also be included in the drainage area maps. The direction of flow for each drainage area must be indicated by arrows. 3) Drainage computations for pre and post construction conditions during the 2, 10, 50 and 100 year rain events. 4) Time of concentration calculations. 4) An electronic copy of any computer modeling used for the drainage computations. 5) See also the attached Drainage Permits Checklist for more information. Once a drainage permit application is submitted, a thorough review will be completed and additional information may be requested. For questions regards these comments, contact Jason Swenson, Metro Water Resources, at jason.swenson@state.mn.us or 651-234-7539.

Consistent with the County Comprehensive Plan and County Codes, the following are comments and recommended conditions of approval and as potential requirements for any necessary permits to be issued for the project: 1. As an overall comment, prior to the next stage of plans and plat / site plans approval, the County would like to review and approve plans of detailed intersection and related segment geometric design plans with phasing and planned implementation steps and schedules. If the opportunity is not allowed for a reasonable review of such, this could lead to delays in the permitting process and potential major revisions to plans and right of way. The County is available to meet on project management or design meetings. 2. Plans for Bluff Creek Blvd at and from CSAH 17 / Powers Blvd look adequate as long as 2- lanes are maintained on the ingress side to the local roundabout, and 3-lanes are maintained on the egress side to Powers Blvd and the traffic signal intersection there. The exact width for the ingress should be a minimum of 28-ft face-to-face and preferably closer to 30-ft to accept dual LTs in. A cross-section detail should be provided for Bluff Creek Blvd as well as a plan and profile showing the vertical profile from the center-line of Powers Blvd to the internal roundabout. 3. As a note, the geometric design of the internal (City) roundabout (ICD=125 ft) could be (or should be) improved—contact the County if the City would like additional feedback. 4. The Bluff Creek Blvd connection to the existing traffic signal at Powers Blvd/ CSAH 17 and US 212 will require traffic signal modifications and upgrades. Some form of contract / permit and surety with the County will be required for design, construction, re-timing / re- programming, and final inspection for the traffic signal and roadway approach and loop detection facilities. Striping and restriping of lanes and/or crosswalks may be needed to be incorporated into the project. The modification of the existing pedestrian push buttons / APS system may also be needed. Please contact the County and MnDOT to set up a scoping and design meeting. In addition, an intersection detail and traffic signal layout and wiring plan will be required to update the current record traffic signal plan. 5. The intersection of Sunset Trail / Lyman Blvd will need to be reviewed in detail for intersection control alternatives. Intersection traffic operations at this location are a concern and it may be that access needs to be restricted to right-in / right-out until such time that higher order intersection facilities are available and/or provided for. 6. The proposed cross-section of Sunset Trail from Lyman Blvd (CSAH 18) to the south will need to be widened five (5) feet to account for this access condition as well as for two turn lanes out and enough space for truck turning movements in. The cross-section should be 22- ft in; and 27-ft out (10-17-ft). A cross-section detail should be provided for Bluff Creek Blvd as well as a plan and profile showing the vertical profile and alignment plan from the development’s internal street intersection to the far side of Lyman Blvd intersection, to include the existing street on the north side of the intersection. Further changes to Sunset Trail and its alignment may be required. 7. A full right of way intersection detail of the Sunset Trail and Lyman Blvd will need to be provided to show plans for a future traffic signal layout, wiring, loop detection, and corridor interconnection plan. In addition, numerous utilities are in place in the NW quadrant and some are being looked at to be relocated, such that a utility plan may also be required. Pedestrian ramps and other improvements will be required including pedestrian push buttons / APS systems. In addition, intersection lighting will need to be reviewed and included if not adequate as determined by the County. Contract / permit and surety with the County will be required for design, construction, and final inspection for the intersection connection, and if approved traffic signal and roadway approach facilities. Striping and restriping of lanes and/or crosswalks may be needed to be incorporated into the project. 8. The proposed vertical profile of Sunset Trail from Lyman Blvd (CSAH 18) to the south looks overly steep and will need to be revised to provide 100-feet of 2% max profile and match to the existing Lyman Blvd grade. A check for future loops and/or video camera signal detection may also be required. 9. The contour and grading of the site will need to factor in additional roadway width to include a right turn lane from Lyman Blvd to Powers Blvd. with the existing right turn lane converting to a through lane in future plans. The plat and the separate site plans’ final grading plans and right of way along both CSAH 18 and CSAH 17 will need to be reviewed and approved to show how this is set up for the planned future CSAH 18 future plans. Prior to next stage grading and plat approval, the County would like to review and approve an exhibit drawing showing a cross section of Lyman Blvd on both ends of the plat edges. The cross sections would show the future road improvements and how these improvements might affect the subject lots and any other plat or lot proposed improvements. The two cross sections should be referenced to a plan view at 1:40 scale from center of existing ROW and existing grade, with notes on proposed grades for the roadway and subject lots. 10. The field entrance on the south side of Lyman Blvd approximately 400 ft. east of Sunset Trail must be removed and replaced with full B curb. 11. As part of our review of the preliminary plans, the following are also noted: the City stubbed in a new water main at the SW quadrant of Powers Blvd and Lyman Blvd (NE quadrant of the property). County has fiber conduit and vaults along the south side of Lyman Blvd the entire length of this property. Utility plan shows the casing outside of the roadway on Sunset Trail. Proposed grading plans and utility plans will need further review to show and resolve these conflicts. 12. Prior to any work affecting or on County highways or in County right of way, the applicant shall coordinate plans with the County Engineer and obtain a Utility or Excavating/Filling/Grading Permit(s) from Carver County Public Works: (http://www.co.carver.mn.us/how-do-i/apply-for/a-permit). Final details of locations, grades, and profiles affecting County roads as well as any utility connections will need to be reviewed and approved prior to any permits. 13. Any damages, modifications, or changes incurred on County highways from current or approved conditions will need to remedied or updated at development expense, including costs incurred by the County. These are comments at this time. If you have any questions or need further assistance, please do not hesitate to contact me at dmccormick@co.carver.mn.us or by phone at (952) 466-5208.

The property is currently zoned Planned Unit Development – Regional Commercial District (PUD-RC). 2. The property is guided in the Land Use Plan for Office or Regional Commercial. 3. The legal description of the property is: See Exhibit A. 4. SUBDIVISION The findings necessary for approval of the preliminary plat have been satisfied: a. The proposed subdivision is consistent with the zoning ordinance; b. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city's 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 stormwater drainage are suitable for the proposed development; d.

The following trees may be used to meet planting requirements: Scientific Name Common Name Overstory Trees Acer saccharum spp. Maple, all varieties, except platanoides Carya ovata Shagbark Hickory Celtis occidentalis Hackberry Juglans nigra Black Walnut Quercus spp. Oak, all varieties Aesculus glabra Ohio Buckeye Betula nigra Birch, River Betula papyrifera Birch, paper Catalpa speciosa Northern Catalpa Ginkgo biloba Ginkgo Gleditsia triacanthos inermis, spp. Honeylocust, thornless - all varieties Gymnocladus dioicus Coffeetree, Kentucky Tilia spp. Linden, all varieties Ulmus spp. ELM, DED-resistant varieties Ornamental Trees Acer ginnala* Maple, Amur Amelanchier spp. Serviceberry or Juneberry Crataegus spp. Hawthorn, all varieties Malus spp. Crabapple, assorted flowering-Varieties Ostrya virginiana Ironwood Populus tremuloides Aspen Sorbus spp. Ash, Mountain, all varieties Phellodendron amurense Amur Corktree Prunus cerasifera "Newport" Plum, Newport Prunus triloba Plum, flowering or Rose Tree of China Prunus virginiana "Schubert" Chokeberry, Schubert Syringa reticulata Lilac, Japanese tree Conifers Abies balsamea Fir, Balsam Abies concolor Fir, Concolor Larix laricina Tamarack Picea abies Spruce, Norway Picea glauca Spruce, White Picea glauca densata Spruce, Black Hills Pinus nigra Pine, Austrian Pinus ponderosa Pine, Ponderosa Pinus resinosa Pine, Norway Pinus strobus Pine, White Pinus sylvestris Pine, Scotch Pseudotsuga menziesii Fir, Douglas Thuja occidentalis Arborvitae Thuja occidentalis "Techny" Techny Arborvitae * These trees shall be restricted; quantities and location must be approved by the city in a landscape plan. (2) The tree(s) must be installed prior to receiving a certificate of occupancy or financial guarantees acceptable to the city must be provided t o ensure timely installation. (3) All areas disturbed by site grading and/or construction must be seeded or sodded immediately upon completion of work to minimize erosion. When certificates of occupancy are requested prior to the satisfaction of this requirement, financial guarantees acceptable to the city must be provided. (4) No dead trees or uprooted stumps shall remain after development. On -site burial or burning is not permitted. (5) Landscaped buffers around the exterior of the subdivision shall be required by the city when the plat is contiguous with collector or arterial streets as defined in the comprehensive plan and where the plat is adjacent to more intensive land uses. Required buffering shall consist of berms and landscape material consis ting of a mix of trees and shrubs and/or tree preservation areas. No fences will be permitted between the required buffer and the collector or arterial street. Where appropriate, the city may require additional lot depth and area on lots containing the buf fer so that it can be adequately accommodated and the homes protected from impacts. Lot depths and areas may be increased by 25 percent over zoning district standards. The landscape plan must be developed with the preliminary and final plat submittals for city approval. Appropriate financial guarantees acceptable to the city shall be required. (b) It is the policy of the city to preserve natural woodland areas throughout the city and with respect to specific site development to retain as far as practical, substantial tree stands which can be incorporated into the overall landscape plan. (c) No tree removal shall be permitted except as approved in a subdivision, planned unit development or site plan application. Removal of trees prior to city approval will result in the issuance of a citation. The cleared area shall be replanted at a rate of two times the DBH inches (DBH means diameter measured at breast height, 4 5/10 feet above the ground) of trees removed, if known, or one tree per 1,089 square feet of replacement area with the required replacement area calculated at two times the canopy coverage area that was removed. Additionally, the development review process shall be halted and the developer shall be required to resubmit revised existing site condit ion and tree inventory plans and new landscaping plans incorporating the additional planting requirements. (d) The following standards shall be used in evaluating subdivisions and site plans: (1) It is a policy of the City of Chanhassen to protect the integrity of the natural environment through the preservation, protection, and planting of trees. The city finds that trees provide many benefits including: stabilization of the soil by the prevention of erosion and sedimentation, reduction of stormwater runoff and the costs associated therewith, improvement of air quality, reduction of noise pollution, control of urban heat island effect, protection and increase of property values, protection of privacy, energy conservation through natural insulation, cont rol of drainage and restoration of denuded soil subsequent to construction and grading, protection from severe weather, providing habitat for birds and other wildlife, conservation and enhancement of city's physical and aesthetic environment, reforestation of open lands, and general protection and enhancement of the quality of life and general welfare of the city. It is therefore the purpose of this section to provide regulations related to the cutting, removal, or killing of trees on construction and development sites and to ensure the protection and preservation of the natural environment and beauty of the City of Chanhassen. (2) Prior to the submittal of development plans, a tree survey of the site shall be prepared by a registered landscape architect, licensed forester, or other professional approved by the city. This survey shall include the species, DBH size, condition, location of all trees over ten inches in diameter and any damaged or diseased trees on site. All significant special, damaged or dise ased trees shall be tagged and identified by number on the survey. A delineation of the existing canopy coverage area(s) which outlines all areas covered by tree canopy shall be included as part of the survey. Additionally, all damaged and diseased trees s hall be cataloged with the nature and extent of any damage or disease specified. a. Based on this survey and either site observation and measurement or a current aerial photograph (taken within one year of the date of plan submittal) interpretation, the following shall be calculated: 1. Base line canopy coverage. 2. Minimum canopy coverage requirements. b. The following table shall be used to determine the minimum amount of canopy coverage that must be maintained or provided on-site as part of the development. It shall represent the minimum canopy coverage, consisting of existing tree canopy and/or additional t rees required for the site. Existing wetland areas, bluff areas, and dedicated park land located on site shall be excluded from the calculation of site area in the determination of site coverage. If a forested area is to be dedicated to the city for park l and, then this area shall not be included in the base line canopy coverage area calculation nor shall it count towards the minimum canopy coverage for the site. Base Line Canopy Coverage Per Acre Comprehensive Plan Designation 80—100% 60—79% 40—59% 20—39% 19% or less Commercial/industrial/institutional 28% 25% 20% 14% 10% High density residential 35% 30% 25% 20% 15% Medium density residential 40% 35% 30% 25% 20% Low density residential 55% 46% 35% 30% 25% Large lot residential 68% 56% 43% 35% 25% Base line canopy coverage is the canopy coverage existing at the time the development application is filed with the city. Minimum canopy coverage is determined by using the matrix. c. Priority shall be given to retaining stands of trees and undisturbed wooded lands over individual specimen trees that will be incorporated into the development. No more than ten percent of the canopy retention requirement may be met by an individual tree that is not included within a designated woodland area. d. For developments that do not meet the minimum canopy coverage, the developer shall be required to develop a forestation plan to bring the total canopy coverage up to the minimum requirement. Where existing woodlands are removed or there is a loss of trees that would otherwise be used to meet the canopy coverage retention requirement, the developer shall develop a woodland replacement plan. The replacement plan must designate an area at least one and two-tenths (1.2) times the removed canopy coverage area that shall be planted with replacement trees for those removed. These plans shall locate additional trees either as a continuation of existing stands of trees that are to be preserved or create new stands of trees in desirable locations such as along roadway corridors, on the north and west perimeters of the development, in common open areas, or adjacent to park facilities. e. The following criteria shall be followed in establishing minimum canopy coverage: 1. When planting trees, one tree shall be deemed to provide 1,089 square feet of required canopy coverage; 2. Trees must be from the approved list of desirable species (preference given for trees designated as native); 3. No more than ten percent of t he trees may be from any one tree species, no more than 20 percent of the trees may be from any one genus, and no more than 30 percent of trees from any one family; 4. Overstory trees shall be at least 2½-inch caliper and understory trees shall be a minimum of 1½-inch caliper; 5. Conifer trees shall be a minimum of six feet in height; 6. Plant materials used for the reforestation shall be of a similar species as vegetation found on-site; 7. Trees shall be used that are appropriate to the soil condit ions found on site; 8. Trees shall be from certified nursery stock as defined and controlled by M.S. §§ 18.44 through 18.61, the Plant Pest Act; and 9. Not less than 75 percent of the total trees required shall be overstory species. (3) In order to calculate the tree removal area of the single-family detached development the applicant must include the front 105 feet of each lot within the tree removal area of the development. If a front setback variance is approved as part of the subdivision review pr ocess, the depth of the area calculated for tree removal on the lot may be reduced by the amount of the front yard setback variance. (4) Minimizing the tree loss should be achieved by any combination of the following: a. Realignment of streets, utilities and lot lines. b. Consideration of alternative utility configurations such as the use of ejector pumps, force mains, or revised home elevations to minimize grading. c. Reductions in roadway width and right-of-way and increase in street grade up to ten percent when the applicant can demonstrate that significant tree preservation is directly related to the modification. d. Use of private streets in lieu of public streets. e. Variation in street radius and design speed. f. Modified grading plans. g. Within PUDs, the city council may consider waiving minimum lot area requirements and/or density transfers as long as it can be demonstrated by the applicant that tree preservation can be enhanced. In no case shall overall project d ensities exceed what is allowed by the comprehensive plan. The greater the level of preservation, the greater flexibility will be considered by the city. h. Within PUDs, variations to building setback lines, provided a minimum 20 -foot building separation is maintained between buildings on adjacent lots. The setback variations shall be established and recorded as part of the plat approval. (5) Trees designated for preservation shall be protected by snow fences with clearly marked signage specifying that the area is off limits for construction activities, or other means acceptable to the city, prior to land preparation or construction activities. Protective barriers in locations determined by the city must remain in place until all construction activities are terminated. No equipment, chemicals, soil deposits, or construction materials shall be placed within the protective barriers. All understory trees and natural vegetation should be preserved within the boundaries of the protective areas. Where this protection area cannot be maintained or would otherwise render lots undevelopable, an alternate protection, mitigation or tree replacement plan may be considered and approved by the city. This plan may include the use of retaining walls, installation of aerati on systems, requirement for post-construction deep root fertilization and soil aeration, or construction vehicle ramp systems. (6) At the city's discretion, conservation easements may be required to protect designated tree preservation areas. Such easements shall be permanently marked and signed as a conservation area with low profile monumentation acceptable to the city. A monument is required for each 300 linear feet of tree conservation area. Within designated woodland areas, the city shall encourage the use of indigenous grasses and plant species to more closely resemble a natural area. Homeowners associations shall be responsible for the maintenance of vegetation in common areas. Individual property owners shall be responsible for the maintenance of v egetation on their property. The planting of trees in excess of those required by this section is permitted within the designated woodland area. (7) During the removal process, trees shall be removed so as to prevent blocking of public rights -of- way or interfering with overhead utility lines. (8) The removal of diseased and damaged trees is permissible only if they cannot be saved. These trees shall not be counted when computing the base line tree canopy coverage. (9) If any protected significant trees are removed or killed or there is a loss of trees as the result of construction activities, the city requires replacement at the rate of two diameter inches per each inch of DBH of the removed, killed, or lost trees. The replacement trees shall be at lea st 2½ inches in diameter and will be species that conform to the "list of desirable tree species" for Planting in Chanhassen. No more than ten percent of the trees may be from any one tree species. Other species or sizes may be used as replacement trees subject to approval by the city. Alternately, at the city's discretion, if a developer removes trees within a protected area, the canopy coverage area shall be calculated for that area and a replacement area two times the canopy coverage area that was removed shall be planted. One tree shall be planted for each 1,089 square feet of required replacement area. Trees shall be from the list of desirable tree species, no more than ten percent of trees from any one tree species, average 2½-inch diameter, a similar species as vegetation existing on-site, and appropriate to the soil conditions. For any replacement trees that cannot be planted on the original site due to space restrictions, the developer shall pay the city the value of the trees, including material and installation, in to the community tree planting fund. (10) Financial guarantees acceptable to the city shall be required to ensure satisfactory installation of landscaping requirements. (Ord. No. 33-D, § 6.6, 2-25-85; Ord. No. 153, § 2, 11-4-91; Ord.

(a) All subdivisions shall comply with surface water management criteria as set forth in Chapter 19 of the City Code. the city's surface water management plan dated August 2006, which is incorporated herein by this reference. (b) In accordance with the city's surface water management plan as a condition of subdivisio n approval, sSubdividersApplicants shall pay a Surfacetormwater Management Feewater quality and water quantity connection charge. The feecharge shall be based on the developable land. Undeveloped areas such as wetlands and buffers placed into an Outlot, public parks, and public right -of-way are exempt from these fees. upon the gross area of the subdivision less the area to be dedicated to the city for ponding, parks and wetland, and right-of-way for state highways, county roads, and local arterial roadways. The fee schedule connection charges per acre is for water quality and water quantity isare outlined in subsection 4-30(c)3. (c) The applicant subdivision will be given a credit for providing oversized on-site stormwater managementquality improvements that are designed to treat runoff from outside the proposed projectsubdivision to LWMPNURP standards. The Ffee credit will be calculated using the following formula: the percentage of Water Quality Volume oversized compared to the Water Quality Volume required for the project, limited to a maximum of 100%. The per acre feewater quality connection charge will be multiplied by the on-site drainage area for water quality treatment facilities. This value will then be multiplied by 50 percent. The subdivision will also be given a credit for on -site stormwater quality improvements that are oversized to treat runoff from property outside the subdivision to NURP standards. The credit will be calculated using the following formula: The per acre water quality connection charge will be multiplied by the off -site drainage area for water quality treatment facilities. This value will then be multiplied by 50 percent. A fee cCredit will not be granted if the stormwater from contributing off-site areas is already treated to LWMPNURP standards. If there is opportunity to oversize larger than the 100% maximum Water Quality Volume amount, the City may choose to enter into a cost share for the additional oversizing. The water quality connection charges that correspond to the land uses that contribute to the stormwater ponds will be used to calcu late credits. The charge for lots oversized due to individual on -site sewage disposal and water systems will be reduced to the charge that would be imposed on a one-half-acre lot. An additional charge will then be imposed if the lot is further subdivided less a credit for the charge previously paid. The charge shall be paid in cash before the subdivision is approved by the city unless the city and subdivider agree that the charge may be assessed against the property. Property being subdivided shall be exempt from the stormwater management feequality and water quantity connection charges imposed by this section if the charges were paid or assessed in conjunction with a previous subdivision of the property and if the property is not being zoned to a classification with a higher charge.

(a) The subdivider shall submit engineering plans and specifications satisfactory to the city for all required improvements, as listed or as specified in this chapter. These improvements must be initiated within one year of final plat approval and completed within two years. (b) The following public improvements are required in every plat: (1) All subdivision boundary corners, block and lot corners, street intersection corners and points of tangency and curvature shall be marked with durable iron or steel monuments meeting the minimum requirements of state law. The city may, when a subdivision is es sentially complete, require a development to have the plat restaked to replace the original monuments destroyed or obliterated during the construction process. (2) Stormwater management as required per City Code ChapterSection 19. As a rule, the surface water discharge rate from the subdivision is to be retained at the predevelopment rate for a 100 - year, 24-hour storm event through the use of surface water detention/retention facilities or other appropriate means as approved by the city engineer. (3) Every roadway shall have an adequate sub-base and shall be improved with a bituminous or concrete surface in accordance with the design standards specified by the city for urban or rural sections. Except in areas where lot widths excee d 100 feet or topography or tree cover dictates otherwise, grading shall provide for easy installation of sidewalks. (4) Concrete curb and gutter shall be required for all urban street sections. (5) Sidewalks may be required. The following criteria sha ll be used in determining if sidewalks are to be included in a development: a. Sidewalks that connect to existing sidewalks within adjacent developed areas. b. Sidewalks that connect neighborhoods to adjacent schools, parks and neighborhood commercial areas. c. Sidewalks that connect neighborhoods to existing neighborhoods, within adjacent developed areas, and proposed trails as shown in the City of Chanhassen Comprehensive Plan. d.

(1312) Arterial and collector roadways abutting a proposed subdivision must be improved in accordance with the city's adopted five-year capital improvement plan. If there is a nexus between the need for the improvement and the subdivision, the subdivider must constr uct the improvement or pay a proportionate fee to allow the city to construct the improvement. If the construction work is undertaken by the subdivider, the city will reimburse the subdivision 40 percent of the cost for reconstructing a two lane roadway section and 50 percent of the cost of widening a roadway from two lanes to four lanes, or upgrading a roadway from a rural design to an urban section. In lieu of the subdivider performing the construction work, at the city's option, the subdivider shall pay an equivalent fee to the city, based upon estimated construction costs. The fee shall be deposited in a dedicated fund for the purpose for which it was collected. (1413) The developer is required to install public improvements including, but not limited to, sanitary sewer, water main, storm sewer and urban streets to the property boundary to provide future extension to adjacent properties. (c) Prior to the city signing the final plat and prior to the construction of any improvements or site grading, the developer shall provide the city with a letter of credit or cash escrow to insure that all improvements required by this chapter will be installed and paid for at no city expense. For improvements to be installed by the developer, the developer is obligat ed to install and complete all such improvements at his or her own expense and under the supervision and inspection of the city. For improvements which the city agrees to install, the developer shall pay the cost of such improvements through payment of special assessments. As security to the city for installation of the improvements or the payment of special assessments, the developer shall be required to file a cash escrow or letter of credit in an amount and form acceptable to the city to cover the cost of all improvements and special assessments.

(a) As a prerequisite to subdivision approval, subdividers shall dedicate land for parks, playgrounds, public open spaces and trails and/or shall make a cash contribution to the city 's park fund and trail fund, as provided by this section. (b) Land to be dedicated shall be reasonably suitable for its intended use and shall be at a location convenient to the people to be served. Factors used in evaluating the adequacy of proposed par k and recreation areas shall include, size, shape, topography, geology, hydrology, tree cover, access and location. (c) The park and recreation committee shall recommend to the city council the buildable land dedication and cash contribution requirements for proposed subdivisions. (d) If the property being subdivided was previously subdivided, a credit will be given for similar requirements satisfied in conjunction with the previous subdivision. Requirements will be calculated based upon the increase in the population calculation and any change from residential to nonresidential or nonresidential to residential. (e) When a proposed park, playground, recreational area, school site or other public ground has been indicated in the city's official map or c omprehensive plan and is located in whole or in part within a proposed subdivision, it shall be designated as such on the plat and shall be dedicated to the appropriate governmental unit. If the subdivider elects not to dedicate an area in excess of the buildable land required hereunder for such proposed public site, the city may consider acquiring the site through purchase or condemnation. (f) Land area conveyed or dedicated to the city shall not be used in calculating density requirements of chapter 20 and shall be in addition to and not in lieu of open space requirements for planned unit developments. (g) Where private open space for park and recreation purposes is provided in a proposed subdivision, such areas may be used for credit, at the discretio n of the city council, against the requirement of dedication for park and recreation purposes, provided the city council finds it is in the public interest to do so. (h) The city, upon consideration of the particular type of development, may require larg er or lesser parcels of buildable land to be dedicated if the city determines that present or future residents would require greater or lesser land for park and playground purposes. (i) In residential subdivisions, one acre of buildable land shall be conveyed to the city by warranty deed for every 75 people the subdivided land could house based upon the following population calculations: Single-family detached dwelling per lot 3.5 persons Two-family dwelling per dwelling unit 3.0 persons Apartment, townhouses, condominiums and other dwelling units, per bedroom 1.0 persons (j) In subdivisions other than residential subdivisions, either a cash donation equal to ten percent of the fair market value of the buildable land being subdivided or a combination thereof, shall be conveyed to the city. (k) In lieu of a park land donation, the city may require an equivalent cash donation based upon average buildable land value in the city. The cash dedication requirement shall be established annually by the city council. (l) In lieu of a trail donation, trail construction, or trail easement dedication, the city may require a cash donation for the trail system. The cash dedication requirement shall be established annually by the city council. (m) The city may elect to receive a combination of cash, land and development of the land for park use. The fair market value of the buildable land, at the time of final subdivision approval, the city wants and the value of the development of the land shall be calculated. That amount shall be subtracted from the cash contribution required by subsection (k) above. The remainder shall be the cash contribution requirement. (n) "Fair market value" shall be determined as of the time of final subdivision approval in accordance with the following: (1) The city and the developer may agree as to the fair market value; or (2) The fair market value may be based upon a current appraisal submitted to the city by the subdivider at the subdivider's expense. (3) If the city disputes such appraisal, the city may, at the subdivider's expense, obtain an appraisal of the property by a qualified real estate appraiser, which appraisal shall be conclusive evidence of the fair market value of the land. (o) Planned developments with mixed land uses shall make cash and/or land contributions in accordance with this section based upon the percentage of land devoted to the various uses. (p) Park dedication fees shall be paid at the time of final subdivision recording. (q) The cash contributions for parks and trails shall be deposited in either the city's park and recreation development fund or multipurpose pedestrian trail fund and shall be used only for park acquisition or development and trail acquisition or development. (r) If a subdivider is unwilling or unable to make a commitment to the city as to the type of building that will be constructed on lots in the proposed subdivision, then the land and cash contribution requirement will be a reasonable amount as determined by the city council. (s) Wetlands, ponding areas and drainage ways accepted by the city shall not be considered in the park land and/or cash contribution to the city. (t) Subdividers of land abutting streets that have been designated in the city's comprehensive trail plan for the installation of a trail shall be required to dedicate the land for the trail to the c ity and construct the trail. An appropriate trail fee credit shall be granted. (Ord. No. 85, § 2, 3-14-88; Ord. No. 182, §§ 1, 2, 3-8-93; Ord. No. 198, § 1, 2-14-94; Ord.

The analysis of flood levels, storage volumes and discharge rates for detention basins shall utilize the design storm/freeboard evaluation storm concept. (3) Minor drainage systems (storm sewer) shall be analyzed and designed to protect for the 10-year frequency rainfall, and shall be evaluated for the 100-year frequency rainfall. Full pipe flow analysis shall be used unless special conditions can be demonstrated to consider pressure flow. (4) The rational method is the accepted design method for the design of minor systems (storm sewer). The preferred method of design would be a method utilizing a hydrograph approach with factors for land use and soil moisture conditions. NRCS methodology is not acceptable for minor system design unless approved by the city engineer. (5) Landlocked stormwater basins shall be designed to hold back-to-back 100-year storms. For landlocked areas, available freeboard and infiltration capacity of in-place soils should be analyzed (if analyzed for unfrozen soil conditions). (d) Peak Discharge Rates.

(2) The construction of detention basins will involve the direct participation of individual developers. Where regional basins serve multiple properties and may lie outside of t he ownership of the specific development, the city and WDs will take an active role on implementing policy. Because the basis for the hydrology is based on the developer's grading plan, the developer is required to obtain and submit the certification of a licensed engineer that the detention areas are constructed to the specifications of the approved design.

SURFACE WATER MANAGEMENT Chanhassen, Minnesota, Code of Ordinances Page 12 Water Level Diagram (2) The facility design shall provide adequate live storage to provide protection from the design storm, consistent with lowest building elevation standards. Lowest building floor elevation is defined as the lowest slab elevation for a home or building, including basements and crawl spaces. The lowest building floor elevation for structures adjacent to wetlands and water bodies shall be an elevation three two feet above the 100-year high water level. (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 treatment consistent with NURP criteria (90 percent removal of TSS and 60 percent removal of TP for a standard NURP particle size distribution); and/or - CITY CODE Chapter 19 - WATER, SEWERS AND SEWAGE DISPOSAL ARTICLE VII. SURFACE WATER MANAGEMENT Chanhassen, Minnesota, Code of Ordinances Page 13 (a) c. For proposed projects in a watershed that directly discharges to a "Prese rve" water feature Developments shall maximize preservation and use of natural detention areas and regional detention areas shall be used to the greatest practical extent. Multiple purpose stormwater facilities are encouraged to maximize maintenance effici ency within proposed developments while providing the proper flood control and water quality features. (b) The construction of detention basins will involve the direct participation of individual developers. Where regional basins serve multiple properties and may lie outside of the ownership of the specific development, the city and WMOs will take an active role on implementing policy however each development shall endeavor to participate. Because the basis for the hydrology is based on the developer's grading plan, the developer is required to obtain and submit the certification of a licensed engineer that the detention areas are constructed to the specifications of the approved design. (c) Developers and/or project proposers shall be responsible for obtaining the legal rights to discharge to an existing regional facility or basin and assuring there is a maintenance agreement in place. (d) For the permanent protection of surface water impoundments and drainage systems the dedication of land or dedication of protective easements are required. Platting of drainage and utility easements or dedication of Outlots over hydrologic features such as floodplains, storm sewers, ponds, ditches, swales, wetlands and the approved buffer strips, and waterways are required. (Table 20 of SWMP), NURP plus enhanced treatment is required as listed below: 1. Stormwater ponds are required to include a sediment forebay at the inlet. The volume of the sediment forebay should be five to 15 percent of the permanent pool surface area. The sediment forebay shall be a minimum of three feet plus the depth for sediment storage. 2. Projects in watersheds that discharge directly to Assumption Creek must incorporate BMPs as outlined in Appendix A C.1, C.2, C.3 and C.5 of the MPCA NPDES construction general permit, and as listed below: i. During construction. aa. All exposed soil areas with a slope of 3:1 or steeper, that have a continuous positive slope to a special water must have temporary erosion protection or permanent cover within three days after the area is no longer actively being worked. All other slopes that have a continuous positive slope to a special water must have temporary erosion protection or permanent cover with in seven days after the area is no longer actively being worked. bb. Temporary sediment basin requirements described in Part III.B.1 -5 of the NPDES construction general permit must be used for common drainage locations that serve an area with five or more acres disturbed at one time. ii. Post construction. The water quality volume that must be treated by the project's permanent stormwater management system described in Part III.C of the NPDES construction general permit shall be one inch of runoff from the new impervious surfaces created by the project. iii. Buffer zone. An undisturbed buffer zone of not less than 100 linear feet from the special water (not including tributaries) shall be maintained at all times. Exceptions from this requirement for areas , such as water crossings or limited water access, are allowed if the permittee fully documents in the SWPPP the circumstances and reasons that the buffer encroachment is necessary. All potential water quality, scenic and other environmental impacts of these exceptions must be minimized and documented in the SWPPP for the project. iv. Temperature controls. The permanent stormwater management system must be designed such that the discharge from the project will minimize any increase in the temperature of tr out stream receiving waters resulting from the 1-, and 2-year 24-hour precipitation events. This includes all tributaries of - CITY CODE Chapter 19 - WATER, SEWERS AND SEWAGE DISPOSAL ARTICLE VII. SURFACE WATER MANAGEMENT Chanhassen, Minnesota, Code of Ordinances Page 14 designated trout streams within the section that the trout stream is located. Projects that discharge to trout streams must minimize the impact using one or more of the following measures, in order of preference: aa. Minimize new impervious surfaces. bb. Minimize the discharge from connected impervious surfaces by discharging to vegetated areas, or grass swales, and through the use o f other nonstructural controls. cc. Infiltration or evapotranspiration of runoff in excess of pre -project conditions (up to the 2-year, 24- hour precipitation event). dd. If ponding is used, the design must include an appropriate combination of measures such as shading, filtered bottom withdrawal, vegetated swale discharges or constructed wetland treatment cells that will limit temperature increases. The pond should be desi gned to draw down in 24 hours or less. ee. Other methods that will minimize any increase in the temperature of the trout stream. ff. For proposed projects in a watershed that directly discharges to an "Improve 1" (Table 20 of SWMP) water feature NURP plus enhanced treatment is required as listed below: A. Stormwater ponds are required to include a sediment forebay at the inlet. The volume of the sediment forebay should be five to 15 percent of the permanent pool surface area. The sediment forebay shall be a minimum of three feet plus the depth for sediment storage. B. Projects in watersheds that discharge directly to Riley or Bluff Cre eks must analyze the downstream system to ensure there is no increase in runoff rates. One way to determine the downstream effects is to extend the analysis downstream to a point where the proposed development represents less than ten percent of the total watershed draining to that point. (b) Skimmers and outlets. (1) Skimming devices should be designed to remove oils and floatable materials up to a one -year frequency event. The skimmer should be set 12 inches below the normal surface water elevation and should control the discharge velocity to 0.5 fps. (2) Outlets shall be evaluated for the need to dissipate energy so as to reduce velocities to permissible levels as allowed by the soil and vegetation. At a minimum, flared end sections should be provided with riprap consistent with Minnesota Department of Transportation standards. For areas with high flows or where excessive erosion occurs or is anticipated, energy dissipation per Federal Highway Administration standards shall be followed. (3) Riprap shall be provided below the channel grade and above the outfall or channel bottom to insure that riprap will not be undermined by scour or rendered ineffective by displacement. Riprap consisting of natural angular stone suitably graded by weight shall be desi gned for anticipated velocities. Riprap shall be placed over a suitable filter material or filter fabric to insure that soil particles do not move through the riprap and reduce its stability. (4) For outlets through berms or roadway embankments and all cu lverts under public traveled streets, anti-seepage collars shall be used (see diagram in this section).

See the Code Comparative Table for full derivation. Sec. 20-401. - Findings intent; rules adopted by reference. (a) Wetlands help maintain water quality, serve to reduce flooding and erosion, act as sources of food and habitat for a variety of fish and wildlife, and are an integral part of the community's nat ural landscape. Wetlands provide the aesthetic benefits of open space and can be used to provide a natural separation of land uses. It is the intent of this article to establish a policy of sound stewardship through coordination of regulations that conserv e, protect, enhance, and result in the no net loss of these environmentally sensitive resources. In addition, it is the intent of the city to promote the restoration of degraded wetlands. (b) The intent of this article is to avoid alteration and degradation destruction of wetlands. When this is not feasible, mitigation must be provided to recreate the function and value of the lost or altered wetlands. (c) This article is adopted in part to implement the Wetland Conservation Act of 1991, as amended (M.S. § 103F.612 et seq.), and the accompanying rules of the Minnesota Board of Water and Soil Resources (Minnesota Rules Chapter 8420, as amended). (d) This article incorporates by reference the act and the rules. Terms used in this article which are defined in the act or the rules have the meanings given there. (Ord. No. 449, § 2, 5-14-07) Sec. 20-402. - Purpose. The purpose of this article is to assure the general health, safety, and welfare of the residents through preservation and conservation of wetlands and sound management of development by: (1) Conducting an inventory and classification of all wetlands within the city and maintaining a comprehensive set of official city maps depicting the approximate location and extent of wetlands. (2) Establishing wetland regulations that are coordinated with the stormwater management water quantity and water quality goals and policies of the Chanhassen Local Surface Water Management Plan. (3) Requiring sound management practices that will protect, conserv e, maintain, enhance and improve the functions and values of wetlands within the community. (4) Requiring measures designed to maintain and improve water quality in streams and lakes. (5) Protecting and enhancing the scenic value of wetlands. (6) Restricting, controlling and mitigating the harmful effects of development on in and around wetlands. (7) Allowing only development that is planned to be compatible with wetland protection and enhancement. (8) Providing standards for the alteration of wetlands when alteration is allowed. (9) Educating and informing the public about the numerous benefits and features of wetlands and the impacts of urbanization. (10) Obtaining protective easements over or acquiring fee title to wetlands and buffers as appropriate. (Ord. No. 449, § 2, 5-14-07) Sec. 20-403. - No net loss. (a) To achieve no net loss of wetland, except as provided under sections 20-417 and 20-418 of this article or authorized by a wetland alteration permit issued by the city, a person may not drain, grade, excavate, fill, burn, remove healthy native vegetation, or otherwise alter or destroy degrade a wetland of any size or type. Any alteration to a wetland permitted by a wetland alteration permit must be fully mitigated so that there is no net loss of wetlands. (b) Wetlands shall be subject to the requirements established herein, as well as restric tions and requirements established by other applicable city ordinances and regulations. The wetland protection regulations shall not be construed to allow anything otherwise prohibited in the zoning district where the wetland area is located. (c) All activities within the city shall comply with the Wetland Conservation Act of 1991, as amended (M.S. § 103F.612 et seq.), and the accompanying rules of the Minnesota Board of Water and Soil Resources (Minnesota Rules Chapter 8420, as amended). Where the requirements of City Code differ from those requirements, the more restrictive shall apply. (Ord. No. 449, § 2, 5-14-07) Sec. 20-404. - Official wetland map. (a) The city shall maintain the official city wetland inventory, which is hereby adop ted by reference. An electronic copy of this map shall be maintained on the city's geographic information system (GIS) database, with both hard and electronic copies being made available for public review upon request. (b) The city wetland inventory shall identify each basin as one of four management categories: Preserve, Manage 1, Manage 2, and Manage 3. These classifications will be determined using Figure 1.1 "Wetland Management Classification Process Flowchart for Basic Wetland Protection" from Minnes ota Routine Assessment Method for Evaluating Wetland Functions (MnRAM Version 3.0), or future versions. (c) The presence or absence of a wetland on the city wetland inventory does not represent a definitive determination as to whether a jurisdictional wetland that would be covered by this article is present. Wetlands identified during a site specific delineation, but not identified by the city wetland inventory, are still subject to the provisions of this article. (d) The city wetland inventory may or may notdoes not depict previously delineated wetland boundaries and shall not be used as such. (e) The city wetland inventory shall be amended by the city from time to time to include any wetlands discovered during the site review process. (Ord. No. 449, § 2, 5-14-07) Sec. 20-405. - Wetland delineation. (a) It is the responsibility of the project applicant to determine whether a wetland exists on a subject property. It is the responsibility of the applicant to complete a wetland delineation and subm it sufficient documentation of the wetland boundary to the city in a wetland delineation report.

Three hard copiesOne electronic copy of the wetland delineation report must be submitted to the city's WCA agent. Additionally, an electronic copy of the delineated wetland boundaries must be submitted in a format compatible with the city's GIS database. Wetland delineations shall be valid for three five years. Wetland delineations completed more than three five years prior may be confirmed and/or updated by a qualified wetland professional through a site visit and submittal of a summary of the findings, a copy of the old delineation, and a map depicting both the original and revised wetland boundaries, where applicable. (b) Wetland delineations do not need to be completed for properties adjacent to a proposed development that is under separate ownership. However, sufficient information must be present ed to demonstrate that any proposed activities shall not directly or indirectly impact adjacent basinsproperty. The applicant shall review readily available information including, but not limited to, the city wetland inventory, national wetland inventory maps, topographic maps, soil survey maps, and recent and historic aerial photographs in preparing this assessment. (Ord. No. 449, § 2, 5-14-07) Sec. 20-406. - Wetland classification. (a) All wetlands delineated under section 20-405 of this article that have not been previously classified, shall be classified using the results from the Minnesota Routine Asses sment Method for Evaluating Wetland Functions (MnRAM Version 3.0), or future versions. (b) A MnRAM shall be completed by the property owner or applicant for each previously unclassified wetland. An electronic version of the MnRAM evaluation must be submitted to and approved by the city to establish the classification of each wetland prior to any alteration or impact to the wetland. (c) MnRAM 3.0 assessments may have been completed by the city as a component of the city wetland inventory. Applicants, however, may appeal the determination, and submit a request to change the classification. To do so, the applicant must submit an electronic copy of the MnRAM for each affected wetlandbasin to the WCA agent. The forms must be filled out by a qualified wetland scientist. The WCA agent will consult with the technical evaluation panel to determine if a change in the classification is warranted. In all cases, the burden to demonstrate the need for a change in classification lies with the applicant. (Ord. No. 449, § 2, 5-14-07) Sec. 20-407. - Permit required. No person shall drain, excavate in the permanent or semi-permanent flooded areas of open water wetlands, or fill a wetland, wholly or partially, or otherwise impact wetlands without first having a wetland replacement plan or other determination approved by the city. Draining, grading, excavating, filling, removing healthy native vegetation, or otherwise altering or degradingdestroying a wetland of any size or type not subject to an exemption under section 20-417 of this article requires a wetland alteration permit. Activity in a wetland requiring a wetland alteration permit includes, but is not limited to: (1) Construction of new streets and utilities. (2) Creation of ponds or dams and alterations of the natural drainageways of watercourses. This shall only be allowed as part of a mitigation project, or to restore or improve the function and value of the wetland. (3) Installation of boardwalks and docks.

The annual report shall include all the information required of annual monitoring reports by Minnesota Rules Chapter 8420.0620 0810subpart 2. The wetland alteration permit holder shall submit annual monitoring reports as required by Minnesota Rules Chapter 8420.06100810. Submission shall continue for at least threefive years or until the replacement wetland is deemed by the technical evaluation panel (TEP) to be fully functional. Where feasible, the city shall require the wetland alteration permit holder to satisfy long term management requirements. (d) Mitigation surety. To ensure that the proposed wetland replacement occurs, the city shall hold either a cash escrow or letter of credit equal to 110 percent of the current value of wetland credits on the open market. An additional escrow account shall be established to ensure that the required monitoring occurs. The monitoring escrow shall be set at 110 percent of the current average monitoring expense as performed by an independent consultant. The monitoring and replacement escrows may be released incrementally as monitoring and replacement are successfully completed. The remaining escrow amount will be returned and the letter of credit terminated upon completion of the monitoring and approval by the technical evaluation panel (TEP). Any interest earned by holding of a c ash escrow shall be the property of the city. (e) Within the Minnehaha Creek Watershed District, 1:1 mitigation is required for excavation within wetlands. (Ord.

It is bordered on the east by the City of Eden Prairie; on the north by Shorewood; and on the west by Victoria and Chaska. Its southern border is the Minnesota River. The City has land in four watersheds: the Carver WMO, Riley-Purgatory-Bluff Creek, Minnehaha Creek, and the Lower Minnesota River Watershed Districts. This Local Water Management Plan (LWMP) was prepared in conformance with Minnesota Statutes 103B.235 and Minnesota Rules 8410. This plan is intended to provide the City of Chanhassen with information and direction in the administration and implementation of water resource management activities within the City during the period 2018-2027. It serves as a guide to projects, provides for effective allocation of resources, and sets forth a funding plan for projects and programs over the next 5 to 10 years. A number of water resources-related problems, issues and requirements were identified in this planning process. These include:  The reissue of the State of Minnesota’s NPDES General Stormwater Permit in 2013 requires local governments such as Chanhassen to adopt and enforce standards and ordinances for development and redevelopment which limits stormwater runoff from sites over one acre in size.  New or expanded maintenance and administrative responsibilities are required in the NPDES permit to control runoff and protect and improve water quality from City owned or maintained land.  All 4 WMO’s are updating their 10 year Comprehensive Plans. The City is required to amend their LWMP to be consistent with each WMO  In order to maintain and/or obtain primary responsibility for managing local water resources additional ordinance revisions are required. The alternative is to defer the authority to the local WMO  Some of the lakes and streams in the City do not meet the state’s water quality standards for recreation and aquatic life.  Stream gullies and escarpments are contributing excess sediment into Bluff Creek and the Minnesota River. The LWMP updates the City’s goals and related policies to address the problems and issues that were evaluated for the updated LWMP. The goals are as follows: Executive Summary Page | v Local Stormwater Management Plan, December 2018 Implementation This LWMP includes an Implementation Plan to help achieve those goals through capital projects, management programs, and operations and maintenance activities. Capital Projects. The Riley-Purgatory-Bluff Creek WD has completed Use Attainability Assessments (UAAs) and/or Total Maximum Daily Load (TMDL) studies for some of the waterbodies in the City. These studies have identified potential actions that could help protect or improve water quality. The City evaluates partnership opportunities with the Districts to undertake priority projects as project plans develop. In addition, the City has been systematically surveying the condition of storm drainage system features. These condition assessments have identified a number of potential improvement projects, and priority actions are included in the Implementation Plan. The Implementation Plan also includes projects to install water quality Best Management Practices (BMPs) with street or other construction projects. Management Programs. The City operates several programs that directly or indirectly affect water resources, including a Public Education and Outreach program. A variety of social and traditional media are also used to inform and educate citizens. City and partnership events, workshops and festivals provide additional opportunities for education. The City of Chanhassen collaborates with the Metropolitan Council to participate in its Citizen Assisted Monitoring Program (CAMP). Volunteer residents take samples from the following lakes: Lake Lucy, Lake Minnewashta, Lake Riley, Lake St. Joe, Lake Susan, and Lotus Lake. Aquatic Invasive Species management is implemented through a partnership with Carver County WMO, Riley Purgatory Bluff Creek Watershed District, and local Lake Associations. Operations and Maintenance Activities. The City undertakes a variety of operations and maintenance actions, including actions required by its NPDES MS4 Permit. These include ongoing water body inventory and condition assessments, erosion control monitoring, street sweeping, stormwater system inspection, maintenance and repairs, road salt management, and a general education and outreach program. Goal 1.Promote abstraction through infiltration, reuse and other methods where practicable to do so to provide flood protection, ground water recharge and improved water quality. Goal 2. Achieve water quality standards in lakes, streams, and wetlands consistent with their designated uses and established classifications. Goal 3. Protect and rehabilitate wetlands to maintain or improve their function and value. Goal 4. Prevent contamination of the aquifers and promote groundwater recharge to maintain base flows in streams and wetlands. Goal 5. Maintain primary responsibility for managing water resources at the local level and continue coordination and cooperation with other agencies and organizations. Goal 6. Cultivate an environmentally literate public to promote an active community role in sustainable management of water resources. Executive Summary Page | vi Local Stormwater Management Plan, December 2018 Plan Updates Section 6 of this Plan sets forth a process to update the LWMP in response to city operations, budget planning, work requirements or WMO plan revisions. The Implementation Plan and Capital Improvement Program (CIP) will be reviewed and updated periodically by the City as needed based on new information or as new opportunities and requirements arise. At a minimum, the CIP will be updated biannually. Major issues that result in potential significant revisions to the LWMP will be forwarded to the Watershed Districts and WMO for discussion and review to determine if the LWMP will require a formal update. Page | vii Local Stormwater Management Plan, December 2018 Figure 1.1. City of Chanhassen in located in the Twin Cities Metro Area, Minnesota. Page | 1-1 Local Stormwater Management Plan, December 2018 1.0 Introduction and Purpose 1.1 PURPOSE OF PLAN The City of Chanhassen is located in Carver County within the Twin Cities Metropolitan Area (Figure 1.1). This Local Water Management Plan (LWMP) describes how the City of Chanhassen will fulfill the requirements of Minnesota Statutes 103B.235 and Minnesota Rules 8410 in the management of the water resources within the city during the period 2018-2027. It is a summary of the city’s management goals and policies, and strategies, including a capital improvement program and review of local policies and ordinances. Minnesota Statutes 103B.231 establishes the purposes of water management planning in the Twin Cities Metropolitan Area as to: 1. Protect, preserve, and use natural surface and groundwater storage and retention systems 2. Minimize public capital expenditures needed to correct flooding and water quality problems 3. Identify and plan for means to effectively protect and improve surface and groundwater quality 4. Establish more uniform local policies and official controls for surface and groundwater management 5. Prevent erosion of soil into surface water systems 6. Promote groundwater recharge 7. Protect and enhance fish and wildlife habitat and water recreational facilities 8. Secure the other benefits associated with the proper management of surface and ground water Minnesota statutes and administrative rules also require that City management of its water resources be consistent with the requirements of the four watershed districts having land within its borders: Riley- Purgatory-Bluff Creek Watershed District; Minnehaha Creek Watershed District; Carver County WMO; and the Lower Minnesota River Watershed Management District. 1.2 RELATIONSHIP TO OTHER CITY PLANS This LWMP is intended to address surface water management; ground water supply and wellhead protection planning are separate from this Plan except as surface water management influences groundwater. 1.2.1 Comprehensive Plan The Comprehensive Plan is a blueprint for how the City manages its land use. The Metropolitan Council in accordance with the Metropolitan Land Planning Act develops and updates regional planning policies and requires that all cities periodically update their Comprehensive Plans to be consistent with those policy plans. Thrive MSP 2040 and the 2040 Water Resources Policy Plan identify certain required elements of local water resources planning. This Local Water Management Plan Update meets those requirements. 1.2.2 Storm Water Pollution Prevention Program Chanhassen is regulated by the State of Minnesota’s National Pollutant Discharge Elimination System (NPDES) General Stormwater Permit as a Municipal Separate Storm Sewer System (MS4). In accordance Page | 1-2 Local Stormwater Management Plan, December 2018 with that permit, the City developed a Storm Water Pollution Prevention Program (SWPPP) comprised of a series of Best Management Practices (BMPs) in six Minimum Control Measure (MCM) areas to prevent pollution and to manage and treat runoff discharged from the city into state waters. An annual report documents the specific actions taken in the previous year, which is presented to the public for review, approved by the City Council, and submitted to the Minnesota Pollution Control Agency (MPCA) for approval. In 2006 the City was one of 30 cities statewide selected by the MPCA to undertake a special Nondegradation Assessment as part of its NPDES permit. The purpose of the study was to assess changes in stormwater runoff volume, total suspended solids (TSS) and total phosphorus (TP) loading since 1988, and to predict how land change expected to 2020 would impact those parameters. The study found that while runoff volumes had increased, pollutant loading had decreased as a result of City and watershed district water quality treatment requirements. A new General Permit became effective August 1, 2013, and the City and other MS4s were required to prepare a new SWPPP and submit obtain renewal of coverage under the permit. Many of those BMPs are incorporated into this LWMP. 1.2.3 Wellhead Protection Plan Minnesota state statutes require the owners and operators of public drinking water systems to prevent contamination of public water supply wells by effectively managing potential contaminant sources in the area which contributes water to those wells. They must prepare a wellhead protection plan which includes: a map showing the boundaries of the delineated wellhead protection area, a vulnerability assessment of the well and the wellhead protection area, an inventory of potential sources of contamination within the wellhead protection area, a plan to manage and monitor existing and proposed potential sources of contamination, and a contingency strategy for an alternate water supply should the water supply be disrupted by contamination or mechanical failure. The City’s Wellhead Protection Plan (WHPP) addresses the ten municipal supply wells used by the City. Initially completed in 2002, it was updated in 2011 to include new wells and additional analysis. The WHPP includes an identification of a Wellhead Protection Area and an assessment of the vulnerability of the wells to contamination. One well, an emergency backup well, was identified as vulnerable to surface contamination, while the other wells were classified as not vulnerable. The uppermost source water aquifer within the Drinking Water Supply Management Area (DWSMA) was identified as having mostly low vulnerability to surface contamination. Infiltration of stormwater is not desirable where the DWSMA indicates the aquifer is vulnerable to contamination from the surface, and other stormwater BMPs are recommended. DWSMA vulnerability is further described at the subwatershed level in Appendix A of this Plan. 1.2.4 Bluff Creek Natural Resources Management Plan The Bluff Creek Natural Resources Management Plan was completed in 1996. The Management Plan identified high-quality natural features for preservation as well as potential restoration projects. To protect this area, several zoning and land use recommendations were intended to minimize new impervious surface, control and limit stormwater runoff and pollutant loading, and protect or enhance wildlife corridors and connectivity. Many of these recommendations were incorporated into the Bluff Creek Overlay District zoning ordinance enacted in 1998. Maintaining and enforcing stormwater Page | 1-3 Local Stormwater Management Plan, December 2018 management requirements through this Plan and the Riley-Purgatory-Bluff Creek Watershed District are integral to achieving the goals of the Bluff Creek Plan. 1.3 RELATIONSHIP TO OTHER PLANS Several agencies manage programs or regulate activities for local stormwater or water resource management. The following sections summarize those relevant to local water management planning. 1.3.1 Metropolitan Council Water Resources Policy Plan The Metropolitan Council’s Water Resources Management Policy Plan is a framework to integrate water resources management and protection with planning for the Metro region’s growth. In 1995, the Metropolitan Land Planning Act was amended to require that each city and township's comprehensive plan include a local water management plan. These local plans need to be consistent with Minnesota Statutes 103B and Metropolitan Land Planning Act requirements. Local water management plans are reviewed by the Met Council as part of the local comprehensive planning process prior to their approval by the WMO and adoption by the city or township. In addition to the local stormwater plan elements required in statute and administrative rule, the Policy Plan expects communities to show that they are committed to the Met Council’s goal of no adverse impact (nondegradation) for area water resources. Local plans should include actions such as ordinances requiring runoff water quality treatment and limiting the rates and volumes of runoff; adopting Best Management Practices for development and redevelopment; and wetland management planning. The Policy Plan places a special emphasis on nondegradation of lakes identified as Priority Lakes. The Met Council defines Priority Lakes as lakes of high regional recreational value that are at least 100 acres in size; supply drinking water; have very good water quality; or have exceptional significance for wildlife habitat. Lakes in Chanhassen that have been designated as Metro Priority Lakes are: Minnewashta, Ann, Lotus, and Riley. 1.3.2 Minnesota River Basin Plan The Minnesota River flows southeast from its source at Big Stone Lake on the South Dakota border to Mankato then northeast to join the Mississippi River at Fort Snelling (about 335 total miles). It covers approximately 16,770 square miles, roughly 10 million acres. Thirteen major watersheds in Minnesota drain into the basin, which touches 37 counties. Most of Chanhassen is located in the Lower Minnesota River subbasin. The 2001 Minnesota River Basin Plan (MPCA 2001) lays out a broad framework for directing environmental programs toward improving water quality in the Minnesota River, its tributaries and other water bodies. Priority actions include reducing nutrient, sediment, and bacteria inputs to the River and improving the health of biologic communities. 1.4 RELATIONSHIP TO OTHER REGULATORY AGENCIES The LWMP is intended to meet requirements outlined in Minnesota Rules 8410 and Minnesota Statutes 103B as well as provide a user-friendly tool for day-to-day management of the City’s water resources. The LWMP provides the following information, as required in the Minn. Statutes 103B.235.  Existing and proposed physical environment and land use within the City  Drainage areas and the volumes, rates, and paths of stormwater runoff  Identification of stormwater storage areas Page | 1-4 Local Stormwater Management Plan, December 2018  Performance standards for water quality and water quantity protection  Implementation program  Capital improvement program The Plan was also written with consideration of the needs, requirements and direction outlined in the following:  Local Water Management Rules – Minn. Rules 8410  Wetland Conservation Act – Minn. Rules 8420  Minnesota Pollution Control Agency Water Quality Standards – Minn. Rules 7050  U.S. Army Corps of Engineers Section 404 Clean Water Act  Metropolitan Council Water Resources Policy Plan May 2005  Riley-Purgatory-Bluff Creek Watershed District Water Management Plan - January 2011  Minnehaha Creek Watershed District Comprehensive Water Resources Management Plan – April 2007/ January 2018  Carver County WMO Comprehensive Water Resources Management Plan – October 2010  Carver County Groundwater Plan - 2016  Lower Minnesota River Watershed District Water Management Plan - December 2011  Metropolitan Surface Water Management Act (Chapter 601, Laws of 1990)  Use Attainability Analyses (UAAs) for lakes and streams in the city  The approved TMDLs for turbidity and fish biotic impairments in Bluff Creek The watershed organizations and their respective jurisdictions within the City are shown on Figure 2.1. The LWMP is intended to satisfy the rules set forth in the current watershed management plans. The City will participate in upcoming revisions, evaluate any future watershed management plan amendments in relation to the LWMP and incorporate items as needed. Page | 2-1 Local Stormwater Management Plan, December 2018 2.0 Regulatory Framework 2.1 CHANHASSEN ORDINANCES AND POLICIES The City has enacted several ordinances to protect and manage its water resources. Chapter 19 of Chanhassen City code addresses design standards and requirements for water and sewers. Article V addresses illicit discharge detection and elimination within Chanhassen storm sewer systems. Article VII spells out development standards and design elements intended to implement the standards and achieve the goals set forth in this plan in order to preserve, protect and improve the city’s surface water resources. Specific elements within Article VII include erosion prevention and sediment control requirements, hydrologic and hydraulic design elements, water quality, rate control and volume reduction requirements. Those design standards include more stringent requirements for developments that discharge into Assumption Creek. That Article also establishes a Surface Water Management Utility and associated fees for operation of this utility. Chapter 20 is the City’s Zoning Code. Article VI establishes wetland management classifications and standards for managing and protecting wetlands in the city. The City of Chanhassen is the responsible Local Government Unit (LGU) for the administration of the Wetland Conservation Act (WCA) in all areas of the city. This article includes standards for setbacks and for establishing and maintaining buffer strips adjacent to wetlands, and policies and procedures for altering wetlands and mitigating impacts to wetland functions and values. Article V establishes the City’s Floodplain Overlay District and floodplain management standards. The ordinance establishes the regulatory flood protection elevation as no lower than two feet above the elevation of the regional flood. The ordinance also establishes what land uses may occur within the Overlay District under what conditions. Article VII sets forth the City’s Shoreland Management District ordinances. The lakes and streams within the city that are regulated under this ordinance are established by management classification. The article includes minimum lot size and width requirements, structure and onsite sewage system setbacks, and limitations on altering and clearing vegetation and adding impervious surface. Article XXVIII establishes bluff protection standards in general. Article XXXI establishes the Bluff Creek Overlay District and standards for protecting the quality and extent of the natural features within the District, which is centered on Bluff Creek. The Overlay District defines a Primary Zone, which is intended to be Open Space, and a Secondary Zone, in which regulated development may occur. Within this Secondary Zone, the ordinance requires a more stringent bluff setback; limits the amount of impervious surface allowed based on bluff slope; encourages terrain- adaptive architecture and density clustering; and requires preservation of natural habitat or, within the Secondary Zone, mitigation of any unavoidable impacts. 2.2 STATE AGENCY REGULATORY FRAMEWORK Many agencies manage programs or regulate activities for local stormwater or water resource management. The following sections summarize those of primary relevance to urban local water management planning. Page | 2-2 Local Stormwater Management Plan, December 2018 2.2.1 Metropolitan Council The Metropolitan Council’s Water Resources Management Policy Plan includes a range of programs administered by various governmental and private agencies for management of water resources in the Metro area. Several of Met Council’s programs of interest to cities include the following:  Development of targeted watershed pollutant loads  Review of watershed and local water plans and comprehensive plans for consistency with metropolitan goals and objectives  Watershed Outlet Monitoring Program (WOMP)  Citizens’ Assisted Lake Monitoring Program (CAMP)  Environmental Information Management System  Regional Water Supply Plan for the Metropolitan Area 2.2.2 Minnesota Pollution Control Agency The MPCA administers several programs applicable to local storm water management planning. The MPCA monitors water quality, sets standards, and implements various controls. Following are two programs related to water quality.  The MPCA manages the National Pollutant Discharge Elimination System (NPDES) Phase II permitting for small municipal separate storm sewer systems (MS4s) and construction and industrial discharge permitting  The MPCA implements the Clean Water Act, which requires that states adopt water quality standards to protect waters of the state. The EPA and MPCA require preparation of Total Maximum Daily Load (TMDL) studies to identify the source of pollutants and plans for bringing the water resources into compliance. Lake Susan, Riley Lake, and Lotus Lake are impaired by excess nutrients; Bluff Creek is impaired by excess turbidity and does not meet state fish biology standards; and the Minnesota River does not meet turbidity standards. Several lakes and the Minnesota River do not meet mercury or PCB standards and have been listed on the MPCA’s 303(d) list of impaired waters. Section 3.2 discusses impaired waters in more detail. 2.2.3 Minnesota Department of Natural Resources The DNR manages and protects the state’s natural resources and operates numerous programs. The department provides technical assistance and information regarding best management practices, natural resource management, incorporating natural resource conservation in land use planning, and lakescaping. The Fisheries Division monitors and improves fisheries within the state. It also promotes fishing opportunities and provides grants to assist in the construction of fishing piers. The Ecological and Water Resources (EWR) Division focuses on an overarching vision of “Healthy Watersheds throughout Minnesota.” The EWR Division also provides the following services:  Maintains an inventory of public waters and operates permit programs for working in public waters or for appropriating public waters;  Oversees the state’s floodplain management program;  Provides local stewardship by coordinating the Mississippi River Critical Area and MNRAA programs and the Shoreland Management program; Page | 2-3 Local Stormwater Management Plan, December 2018  Collects, analyzes, and provides ecological information, including:  Location and management of rare resources (endangered and threatened species, critical habitats, high quality natural communities);  Management of harmful exotic species, fish and wildlife diseases, and negative environmental impacts of human development;  Management and restoration of important ecological processes in river systems and key natural areas; and  Development of information about Minnesota's ecosystems and their significance to a sustainable quality of life. The DNR’s webpage at http://www.dnr.state.mn.us/lakefind/index.html is LakeFinder, a DNR supported tool that combines information from various DNR Divisions, as well as other state agencies, such as Minnesota Pollution Control Agency (water quality) and Minnesota Department of Health (fish consumption). This tool contains data for more than 4,500 lakes and rivers throughout Minnesota. The DNR also provides a variety of specialized programs oriented to property owners or neighborhood groups, such as the Aquatic Plant Management, Urban Fisheries and Fishing in the Neighborhood, Neighborhood Wilds, and Metro Greenways programs. 2.2.4 Minnesota Department of Health The Environmental Health Division of the MDH administers numerous programs of interest to local water management planning, including the following.  Drinking water protection  Wellhead protection  Lake and fish monitoring (in partnership with DNR/MPCA)  Environmental Health Services  Health risk assessment, site assessment, and consultation  Well management The City worked with the MDH to develop a Wellhead Protection Plan (WHPP). 2.2.5 Carver County and Carver SWCD Carver County provides a variety of programs throughout the county that relate to water resources management. County staff manage feedlot and septic system programs, and undertake lake and stream monitoring for water quality where that is not undertaken by a WMO. The County also provides Aquatic Invasive Species (AIS) monitoring and works to stop their spread. Common carp, curlyleaf pondweed, Eurasian water milfoil, and zebra mussels have been found in some of the lakes in Chanhassen. The County has in place an approved groundwater plan, and offers financial assistance to property owners to properly seal unused or abandoned wells. The Carver Soil and Water Conservation District (SWCD) provides outreach and assistance to both urban and agricultural land owners to help them protect and improve lakes, streams, and wetlands in the county. The SWCD promotes environmentally-friendly landscaping, offers financial assistance for shoreline restorations and other Best Management Practices (BMPs), and sponsors student and adult education programming. Page | 2-4 Local Stormwater Management Plan, December 2018 2.2.6 Watershed Districts and WMOs Watershed Management Organizations (WMOs) in the Metro area are required by statute to prepare and administer water management plans that establish watershed-wide goals, policies, and regulations. Local governments are also required by statute to prepare and administer local water management plans that establish local goals, policies, and regulations regarding those water resources management areas that are consistent with the watershed plans. Chanhassen has land within the boundaries of three watershed districts and one county WMO (see Figure 2.1):  Riley-Purgatory-Bluff Creek Watershed District  Minnehaha Creek Watershed District  Lower Minnesota River Watershed District  Carver County WMO Minnehaha Creek WD Local Plan Requirements. The MCWD updated its Watershed Management Plan in 2017. The City of Chanhassen has land in the Lake Virginia, Christmas Lake and Lake Minnetonka subwatersheds. In addition to the general requirements for Local Management Plans set forth in Minnesota Rules 8410, additional items must be addressed in the city’s Local Plan. One focus of the MCWD plan is fostering collaboration between the District and the cities to achieve mutual water and natural resource management goals. To that end the local plan should include:  Locations of publicly-owned lands such as parkland, right of way, or public facilities that may provide opportunities for collaborative stormwater management BMPs.  Lands that may potentially develop or redevelop within the planning timeframe.  Planned Infrastructure improvements or parks or open space acquisitions.  Potential to use development and redevelopment regulation to create incentives to protect water and other natural resources, including controls on removing mature trees.  Ways in which the city’s development review process encourages low impact development, and how the City ensures BMPs are adequately maintained post-construction.  A description of how the City will proactively and at least annually communicate and coordinate with the District on implementation efforts and opportunities for collaboration. A second focus is the MCWD LGU Coordination Plan. Through the Minnehaha Creek Watershed District (MCWD) 2018 Water Management Plan, LGU coordination is identified as an integral component of the Local Water Management Plan. A coordination plan is requested to define a set of protocols that supports ongoing communication and promotes value-added collaboration between the District and LGU. Through these communications, the District and LGU will coordinate programs and resource deployment and be best suited to identify areas of collaboration and partnership. The goal of the coordination plan is to create a framework to maintain awareness of needs and opportunities to co-plan water and land use early in the planning process, while also identifying LGU services and expectations of MCWD. Through the Local Water Plan, the District invites a partnership framework that fosters increased early coordination of land use and water resource management to achieve its water quality goals.

The Riley-Purgatory-Bluff Creek Water Management Plan requires Local Water Plans (LWP) to meet the standards set forth in Minnesota Rules 8410. In addition, cities must submit an annual compliance report describing its annual achievements and progress towards meeting its goals. The LWP should also describe the self-evaluation process the city will use to assess whether those goals and actions should be revised. Lower Minnesota River WD Requirements. The Lower Minnesota River Third Water Management Plan requires Local Water Plans (LWP) to meet the standards set forth in Minnesota Rules 8410. The District will spot-check projects and programs for continued compliance with the approved LWP. Carver County WMO Requirements. The Carver County WMO Comprehensive Water Management Plan requires Local Water Plans (LWP) to meet the standards set forth in Minnesota Rules 8410. In addition, if the City desires to take on regulatory responsibility, the Plan should state so, and describe the local controls, policies, and procedures it will use to administer the permitting program, and demonstrate it has the technical capacity to do so.

Commented [A1]: Update this map Page | 2-8 Local Stormwater Management Plan, December 2018 2.3 WETLAND CONSERVATION ACT The adminitrative responsibilities for the Wetland Conservation Act of 1991 (WCA) will continue to rest with the City. Wetland LGU responsibilities include:  Review and approve wetland delineations and determinations  Review and approve wetland exemption / no-loss applications  Review and approve wetland replacement plan applications  Coordinate Technical Evaluation Panel (TEP) meetings  Send Notices of Application and Decision to the TEP  Enforce wetland replacement monitoring requirements, review monitoring reports and certify replacement wetlands  Work with DNR and Carver County to enforce WCA violations 2.4 RELATIONSHIP TO NPDES STORMWATER PERMIT The City holds a permit from the MPCA to discharge stormwater into waters of the state through the MPCA’s NPDES General Stormwater Permit. The permit specifies that the City must develop, receive MPCA approval of, and implement a Stormwater Pollution Prevention Plan (SWPPP) that addresses a series of Best Management Practices (BMPs) for the following six minimum control measures established by the EPA: 1. Public education and outreach 2. Public participation/involvement 3. Illicit discharge detection and elimination 4. Construction site runoff control 5. Post-construction runoff control 6. Pollution prevention/good housekeeping during municipal operations The City’s previous SWPPP was approved in 2003 and amended in 2006. The State of Minnesota adopted a new NPDES General Stormwater Permit effective August 1, 2013, and the City submitted a permit reapplication in December 2013. Approval of the new permit and SWPPP was received in 2014. Activities and policies to be included in the SWPPP are prescribed in the General Permit, and include many of the actions and policies set forth in this LWMP. 2.5 WATER RESOURCE RELATED AGREEMENTS Water resource-related agreements, including Joint Powers Agreements, are typically struck between agencies or entities with overlapping regulatory interests or geographic similarities. The City has the following agreements:  Cooperative agreements with RPBCWD providing for property use, construction, maintenance and credit-sharing for Susan Park Pond project and Chanhassen High School stormwater reuse projects (2018), Cooperative agreement for the Lake Susan spent-lime water-quality improvement project (2015), Pursuing a cooperative agreement with RPBCWD for efficient joint administration of financial assurances secured for regulatory purposes (2018) Page | 2-9 Local Stormwater Management Plan, December 2018  Memorandum of Agreement Between Carver County Land and Water Services and the City of Chanhassen Regarding Water Quality Education (MS4 Requirements), AIS and Targeted Monitoring Within City Boundaries.  Agreement Between the Carver Soil and Water Conservation District and the City of Chanhassen Relating to Urban Development Review and Site Inspection Services; Wetland Conservation Act; Individual Homeowner Natural Resource Issues.  1996 was the last executed cooperative agreement with MCWD. The city and MCWD are working on an interim agreement for regulatory responsibility during the current Plan and ordinance process Page | 3-1 Local Stormwater Management Plan, December 2018 3.0 Assessment of Problems 3.1 HYDROLOGIC MODELING As part of this Plan, the HydroCAD hydrologic and hydraulic models for the city were updated to include the most recent watershed and basin information. There are fifteen individual HydroCAD models for the City. Issues raised by these models are discussed in Appendix A in the Subwatershed Summaries. The purpose of performing this modeling is for planning level assessments. The models were not calibrated to actual runoff and flows, and are not intended to be flood studies. The models were executed for the 100-year Atlas 14 precipitation event. Model output is quite lengthy and is available electronically. The output files are incorporated into this Plan as Appendix B. In, addition in 2003, the Minnehaha Creek Watershed District (MCWD) completed a multi-year Hydrologic, Hydraulic, and Pollutant Loading Study (HHPLS) to document the physical and biological characteristics of the watershed which includes projected runoff rates and volumes. 3.1.1 Areas of Known Flooding On June 19, 2014, 4.98 inches of rain fell in less than 24 hours at the National Weather Service monitoring site in Chanhassen, a nearly 25-year return interval event. Almost 4.5 inches of rain had fallen in the weeks preceding this storm event, and the ground was saturated and ponds and wetlands were still full. Localized flooding occurred at a number of locations. These included both ongoing problem areas as well as locations where no or minimal flooding had been observed before:  Market Boulevard north of MN T.H. 5  Pipewood Curve  Kerber Boulevard between Saddlebrook Curve and Sierra Trail  Lake Riley Boulevard at Lyman Boulevard  Old 212 near Moon Valley Gravel Pit 3.2 IMPAIRED WATERS Waters that do not meet state water quality standards are listed as “Impaired” by the State of Minnesota will require additional analysis in the form of a Total Maximum Daily Load (TMDL) study. A TMDL is the maximum amount of a pollutant a waterbody can receive and still meet water quality standards. The TMDL study identifies the sources and magnitude of pollutant loading and establishes a numeric load reduction that must be made for each source. Table 3.1. Impaired Waters in Chanhassen.

A measure of the quantity and quality of aquatic life. Source: MPCA 2018 draft 303(d) list of impaired waters. 3.3 TMDLS AND UAAS A TMDL was completed and approved in 2013 for the Bluff Creek biotic integrity and turbidity impairments. A statewide TMDL has been completed for the mercury impairments. The Riley-Purgatory- Bluff Creek Watershed District has completed Use Attainability Analyses (UAAs) for Lake Susan, Lake Lucy, and Lake Ann. The UAAs are scientific assessments of a water body’s physical, chemical, and biological condition. The studies include water quality assessments and recommendations for protective and/or remedial measures for the studied lakes and their directly tributary watersheds. The results of these UAAs provide the City guidelines for water resource improvement projects for these water bodies. Although the UAAs provide some background data that may be used towards preparation of a TMDL they do not meet MPCA criteria for a TMDL document. 3.3.1 Total Maximum Daily Load (TMDL) Studies Bluff Creek Turbidity and Fish Biota TMDL. Bluff Creek is listed by the Minnesota Pollution Control Agency (MPCA) as impaired for aquatic life use due to excess turbidity levels and low fish biota scores. The Turbidity and Fish Biota TMDL was approved in 2013. The Bluff Creek TMDL Biological Stressor Identification Report identified sediment, metals, habitat fragmentation, and flow as stressors to fish biota. Although the TMDL Report discusses all of these stressors, Wasteload Allocations (WLAs) were made only for total suspended solids (TSS), which represents a surrogate for both turbidity and fish biota. Chanhassen’s TSS Wasteload Allocation requires an 88 percent reduction in TSS contributed to the stream. Primary sources of sediment are stream bank and bluff erosion, as well as poorly vegetated ravines and gullies. An inventory and assessment of the Bluff Creek lower valley was completed to identify sites contributing excessive amounts of sediment to Bluff Creek and to determine feasible options for addressing sources of excess sediment delivery to the stream. Five sites were classified as Severe and are highest priority for stabilization and restoration, as was the stream just below the Hennepin County Regional Trail Corridor culvert crossing. The stream channel has downcut significantly below that culvert, and the culvert is being undermined, which could lead to future failure. This large drop also disrupts the connectivity of the creek, fragmenting habitat. Fish and other aquatic organisms are not able to migrate upstream of the culvert. Correction of the severe erosion and addition of a fish passage to reconnect the creek above and below the culvert were identified as priority implementation projects. Page | 3-3 Local Stormwater Management Plan, December 2018 South Metro Mississippi Total Suspended Solids TMDL. The South Metro Mississippi TSS TMDL was approved in 2016. This TMDL would require a 25 percent reduction in TSS load from MS4 communities such as Chanhassen. MS4s can demonstrate they meet this reduction by implementing a suite of BMPs that the MPCA will develop, or by showing that pollutant loads from their community meet or are less than the target load of 154 lbs/acre/year. This proof can be accomplished through water quality monitoring or modeling. Twin Cities Metropolitan Chloride TMDL. This study includes TMDLs for 37 of the 39 lakes and streams in the Metro Area that are impaired by excess chloride levels. The report also identifies high-risk waterbodies where monitoring data indicates that resource is approaching the impairment threshold. There are no chloride-impaired waters in Chanhassen, but the City is located within the tributary area of Minnehaha Creek, which is impaired by excess chloride. In addition, Bluff Creek has been classified as a high-risk waterbody. No specific load reductions were identified for Bluff Creek or any other waterbody in Chanhassen, but the TMDL suggests that all cities where high-risk resources are located consider developing a chloride management plan for those lakes and streams. In general, the TMDL suggests that regardless of whether or not runoff drains to an impaired or high-risk waterbody road authorities and other regulated entities take proactive steps to reduce the application of road salt for winter ice control as much as possible without compromising public safety. 3.3.2 UAAs and Other Studies RPBCWD has conducted several excellent UAAs and valuable studies for several water resources in the city. Three UAAs were updated in 2013. Short descriptions of findings are provided below. In addition A UAA for Rice Marsh Lake and Lake Riley was completed in 2016. Furthermore, the District implemented the Creek Restoration Action Strategy study which includes both Bluff and Riley Creeks. The Upper Riley Creek Sediment Source Assessment was also performed February 2017. The District also conducted a beyond Atlas 14 floodplain evaluation. More detail for each study and assessment is available from the Watershed District (http://www.rpbcwd.org/resources/). Lake Susan. Lake Susan is a shallow, 88 acre lake. Nearly all the surface area is less than 15 feet deep, shallow enough to be almost entirely dominated by rooted aquatic vegetation. Water quality is variable, some years approaching state water quality standards for shallow lakes and some years worse, but on average, the lake does not meet those standards. The Riley-Purgatory-Bluff Creek Management Plan classified Lake Susan as a deep lake, and water quality falls short of deep lake goals. Invasive aquatic vegetation has been an issue in Lake Susan for many years. Curly-leaf pondweed and Eurasian watermilfoil present the greatest threat to the lake. The University of Minnesota has been working to manage the rough fish population in the lake while also trying to reestablish native aquatic vegetation. Modeling completed for the UAA update estimated the amount of nutrient loading from the watershed and from internal and other sources. The North subwatershed, where there are developed areas with little or no water quality treatment, is the largest source of load to the lake. In the South subwatershed, a large wetland in Lake Susan Hills West Park is a likely exporter of phosphorus. Lake Susan also experiences high sediment loading. Total Phosphorus (TP) load to Lake Susan needs to be reduced by 182 pounds per year, or about 25 percent, to meet the shallow lake standard. The UAA identified some pond enhancements and a Page | 3-4 Local Stormwater Management Plan, December 2018 restoration of the identified wetland in Lake Susan Hills Park followed by a lake alum treatment to seal bottom sediments as potential actions to achieve that goal. Lake Lucy and Lake Ann. Water quality in Lake Lucy and Lake Ann has been fairly stable—neither degrading nor improving—in recent years. Lake Lucy currently meets the MPCA shallow lake water quality standards; however, excess phosphorus results in algal blooms and reduced water clarity that does not meet the RPBCWD’s goals. The annual phosphorus loading to Lake Lucy, based on the 2012 water year, indicates nearly half of the phosphorus load to the lake is from watershed runoff. Since the watershed to Lake Lucy has many ponds and wetlands that settle out particulates, much of the phosphorus that reaches Lake Lucy is in the soluble, or non-settleable, form that is readily available for algal uptake. The other primary contributions of phosphorus are internal sources, including release from the bottom sediments and from the dieback of Curlyleaf pondweed. While Lake Ann is currently meeting both the RPBCWD and MPCA water quality goals, the release of phosphorus from the lake sediments appears to lead to periodic blue-green algal blooms suspended below the water surface. During the 2012 water year, more than half of the phosphorus load to Lake Ann came from internal sources, primarily the release from the bottom sediments. Approximately 30 percent of the phosphorus load was from the Lake Ann watershed and discharge from Lake Lucy. Because the lakes currently meet state water quality standards, no specific phosphorus load reductions have been identified. However, to meet Watershed District goals, improve water clarity, and reduce the incidence and severity of algal blooming, the UAA identified a number of management actions. These include: implementing stormwater volume abstraction rules as portions of the watershed develop or redevelop; maximizing the treatment of watershed runoff such as iron-enhanced sand filter pond benches or the use of spent lime treatments to remove soluble phosphorus; and curly-leaf pondweed treatment in Lake Lucy and a whole-lake alum treatment in Lake Ann to help control internal phosphorus load. 3.4 PROBLEMS AND ISSUES Local water management problems, issues, and opportunities were identified by reviewing:  Statutory requirements for Local Water Management Plans  Lake inventory data  Lake UAAs and stream TMDLs  Input solicited from the public, the Environmental Commission, City staff, and state and local agency staff Once the problems and issues were identified staff identified and prioritized potential solutions to help the City of Chanhassen accomplish the goals of this Plan. This section presents those items evaluated to develop the proposed improvements and management studies summarized in the Implementation Plan. Table 3.2. Problems, issues, and opportunities. Water Quality Conditions  Lakes and streams are listed on the Clean Water Act Section 303(d) TMDL List of Impaired Waters.  Nonpoint source pollution reduction is necessary through maintenance practices such as street sweeping, sump manhole cleaning, and pond inspections. Page | 3-5 Local Stormwater Management Plan, December 2018 Drainage and Flooding  Near stream gullies and escarpments should be addressed to control sediment deposition into surface waters and to protect property and infrastructure. There are ongoing opportunities to work with the WMOs to address gully erosion  Subsurface drainage causing icing on public streets and pedestrian pathways. Regulatory Requirements and Operational Policies  Atlas 14 updated precipitation frequency data is available for adoption.  Approaches such as Minimal Impact Development and Integrated Management Practices are available to reduce the public expenditures necessary to control runoff and protect and improve water quality.  The City’s approved NPDES permit and SWPPP requires ordinance revisions and operating program enhancements.  City goals, policies and ordinances to help protect natural resources may need review and refinement. Water-Based Recreation Needs  Water quality should be protected and improved to protect and enhance recreational opportunities.  Control of aquatic invasive species (AIS) is of growing concern. Maintenance Requirements  BMP maintenance and repair requirements have been identified during NPDES inspections, including restoration of storage capacity, repair of erosion, and prevention of future problems.  Street sweeping, sump manhole cleaning, and BMP inspections are necessary on an ongoing basis to help reduce nonpoint source pollutant loads. Education and Outreach  Education and outreach efforts could be expanded with a focus on targeted groups with new and expanded educational opportunities. Continuing to build and grow education opportunities with CCWMO to improve efficiency and reduce duplication of efforts Financial Resources  Financial resources are limited, requiring that projects be prioritized. Groundwater Protection  The LWMP should be coordinated with the Wellhead Protection Program so that policies that encourage infiltration and groundwater recharge are consistent with the policies to protect sensitive areas and groundwater supply recharge areas.  Seminary Fen is a rare calcareous fen and Assumption Creek is a trout stream, both of which are dependent on groundwater. Collaboration Opportunities  There are opportunities for collaboration with other agencies such as the WMOs, the county, and state agencies to leverage expertise and resources to finance and construct improvements. 3.4.1 2006 SWMP Priority Issues The City’s 2006 Surface Water Management Plan identified a number of potential projects and activities to address the then-current problems and issues and to help achieve that Plan’s goals. The highest priority were set forth in Table 45 of that Plan. These included seven structural practices, two ordinance updates, and some inspection and record keeping updates. Most of these high priority actions have been completed. Page | 4-1 Local Stormwater Management Plan, December 2018 4.0 Goals and Policies This section of the Plan outlines goals and policies guiding surface water management in the City of Chanhassen. A goal is a desired end toward which surface water management efforts are directed. Each goal has several corresponding policies that form the governing principals that will be followed to achieve the goals. Table 4.1 summarizes the six water resources management goals. The six goals and the corresponding policies are presented and discussed in more detail in the following pages. Table 4.1. Water resources management goals. Goal Number Goal Area Goal Statement 1 Water Quantity Promote abstraction through infiltration, reuse and other methods where practicable to do so to provide flood protection, ground water recharge and improved water quality. 2 Water Quality Achieve water quality standards in lakes, streams, and wetlands consistent with their designated uses and established classifications. 3 Wetlands Protect and rehabilitate wetlands to maintain or improve their function and value. 4 Groundwater Prevent contamination of the aquifers and promote groundwater recharge to maintain base flows in streams and wetlands. 5 Regulatory Responsibility Maintain primary responsibility for managing water resources at the local level and continue coordination and cooperation with other agencies and organizations. 6 Public Education and Participation Cultivate an environmentally literate public to promote an active community role in sustainable management of water resources. 4.1 GOALS AND POLICIES Water Quantity Development and changes in land use that result in additional impervious surface will result in a corresponding increase in stormwater runoff rates and volumes. This increase can cause flooding and erosion issues in the downstream system. It is important to control these increased runoff rates and volumes in order to ensure reduction of flooding in the downstream system and to control the potential effects of erosive flows on streams and waterways. Storm sewer design within the City of Chanhassen has been largely based upon the precipitation frequency estimates published in the Weather Bureau’s Technical Paper Number 40 (“TP 40”), Rainfall Frequency Atlas of the United States for Durations from 30 Minutes to 24 Hours and Return Periods from 1 to 100 years (Hershfield 1961). In April 2013 the National Oceanic and Atmospheric Administration (NOAA) published Atlas 14, Precipitation – Frequency Atlas of the United States, Volume 8 Version 2.0 to replace TP40. Atlas 14 used a much more robust data set over a much longer time span then was used for TP 40. While the 2-year average return interval and the 10-year average return interval remained relatively unchanged, the 100-year amount increased by 1.38 inches or 23% over the previous estimate Page | 4-2 Local Stormwater Management Plan, December 2018 (Table 4.2). The longer period of record used in developing Atlas 40 allowed for a more statistically accurate estimate of the less frequent events. Table 4.2. Comparison of TP-40 to Atlas 14 event depths. Publication 2-Year, 24 Hour 10-Year, 24 Hour 100-Year, 24 Hour TP 40 2.8” 4.2” 6.0” Atlas 14 2.87” 4.27” 7.38” Even though we now know to design to greater depths for certain events the City’s infrastructure has generally performed very well. However, there have been a few instances where the existing infrastructure was inadequate to accommodate the runoff volumes and/or rates. The City experienced large storm events in 2005, 2009, and 2014. The first 2005 large event occurred on September 3 and 4 and totaled approximately 5.55 inches of rainfall. The second occurred on October 4 and 5, 2005, and totaled approximately 4.61 inches of rainfall. From June 19 through June 20, 2014 the Chanhassen area received approximately 6.23 inches of rainfall. That June Chanhassen received 12.79 inches of rainfall after a wetter than average April and May. While significant damages did not occur from these events, a few areas were subject to high water levels and short-term flooding of streets. Lotus Lake, Lake Riley and Lake Minnewashta all experienced extended high water levels. Residents on these lakes experienced submerged docks and some shoreline erosion damage. Users were subject to the City’s emergency slow/no-wake restrictions for a period of about 15 days. Looking at opportunities to reduce the extent and/or duration of these high water levels is one of the key water quantity issues for the City. Because the lake discharges to Purgatory Creek, the solution is not a simple one. Coordination with RPBCWD, Lotus Lake area residents and the potentially impacted property owners downstream will be a critical step in developing a long term solution that does not push the problem downstream. Another issue that was discovered during the large event of 2005 is the lack of emergency overflows and flow paths in some areas of the City. Ultimately, the City’s focus is to operate and maintain the system so that it continues to function in the way it is intended, and provides flood protection for adjacent properties. During review of storm water management plans it is important for City staff to review the location of emergency overflow paths for storm water infrastructure in new developments. In recent years there has been a paradigm shift in water quantity management. The strategy today is to where possible manage stormwater where it falls, as exemplified by the State of Minnesota’s Minimal Impact Design Standards (MIDS). The emphasis is on reducing the volume of runoff discharged to downstream resources through abstraction, or the permanent retention of runoff on a site through structures and practices such as infiltration, evapotranspiration and capture and reuse. This abstraction can help mitigate the effects of larger storm events. Abstraction has other benefits as well, including minimizing and reducing the amount of pollution reaching our lakes, rivers and streams and recharging groundwater resources. A Flood Hazard Boundary Map dated January 1979 was completed for the City of Chanhassen, which identifies the entire City as a No Special Flood Hazard Area or Zone C. The Flood Insurance Study for Carver County is being updated as part of the FEMA Map Modernization Program. Updated maps are expected to be published in 2018. Maps are available from the FEMA website, www.fema.gov, available at City Hall or from the respective WMO. Page | 4-3 Local Stormwater Management Plan, December 2018 Goal 1. Promote abstraction through infiltration, reuse and other methods where practicable to do so to provide flood protection, ground water recharge and improved water quality. Policy 1.1. Require all developments to construct stormwater best management practices, improve existing practices, and/or contribute to the construction or improvement of a regional facility for the purpose of reducing peak flows and runoff volume generated by the subject development. Policy 1.2. Require all development and redevelopment projects to demonstrate no net increase in the annual runoff water volume discharged from the site compared to pre-development conditions. Policy 1.3. Creative and innovative green site design and Best Management Practices, including infiltration systems and stormwater reuse, will be the preferred practice unless site limitations such as soil conditions, depth to groundwater, and safety preclude the use of these practices. Policy 1.4. Continue to stringently enforce lot coverage requirements set forth in City Code and development contracts. Policy 1.5. Establish and maintain overflow routes for ponds and low areas to provide relief during storm conditions that exceed design conditions. Policy 1.6. Where volume reduction is infeasible and detention ponds are necessary, regional ponding areas, as opposed to individual on-site ponds, should be used to reduce flooding, to control discharge rates, and to provide necessary storage volumes as indicated in this Plan. Policy 1.7. When areas are developed, redeveloped, and as infrastructure is replaced, stormwater facilities should be built and/or upgraded to provide or improve flood management and water quality. Policy 1.8. Encourage the development of new and improvement of existing ponds located upstream of priority water bodies. Policy 1.9. Permanently protect surface water impoundments and drainage systems by requiring the dedication of land and/or protective easements as required. Policy 1.10. Design, operate and maintain newly constructed storm water facilities in accordance with this Plan and NPDES MS4 permit requirements. Policy 1.11. Manage floodplain activities in accordance with all City, state, and federal regulations. Policy 1.12. Require building elevations to provide at least 23 feet of freeboard adjacent to ponding areas and floodplains for all development and redevelopment or when drainage facilities are constructed for an area. Policy 1.13. Preserve existing water storage below 100-year flood elevations. Policy 1.14. Continue management and development of public and private stormwater infrastructure as separate systems. Policy 1.15. The Water Resources Department manages public surface water resources identified in the LWMP and NPDES MS4 permit. Drainage, seeps, and springs on or between single family private parcels is not managed unless specifically identified in the LWMP, NPDES permit, or City ordinance. Page | 4-4 Local Stormwater Management Plan, December 2018 Policy 1.16. Require development and redevelopment stormwater management incorporate the protection of existing and native plant and forest communities. Policy 1.17. Develop a tree preservation and native habitat protection credit consistent with the MCWD credit Policy 1.18. Require development and redevelopment projects and plans incorporate wildlife connectivity opportunities Water Quality The City of Chanhassen seeks to maintain and improve the water quality in its lakes, streams and wetlands to meet or better the State of Minnesota surface water quality standards for lakes and streams. There are many potential sources of water pollution that can negatively impact public safety and the enjoyment of these resources. Stormwater runoff can convey phosphorus, chloride, sediment, oils, debris, and bacteria to downstream waters, increasing algal blooms, reducing water clarity, and impacting fish and other aquatic communities. Excessive volumes and rates of stormwater runoff discharged into channels and streams can erode streambanks, causing additional water quality impacts. One of the City’s chief strategies for achieving its water quality goals is to require development and redevelopment to provide stormwater quality treatment through abstraction of 1.1 inch of runoff from impervious surfaces, or if that is infeasible, to provide treatment by some other means. Other strategies include better management of construction site erosion control measures, disconnecting and reducing the level of impervious cover, reducing the extent of managed lawn areas and replacing them with native vegetation, reducing stream bank erosion, and practicing good housekeeping practices, such as removing leaves from streets and storm drains and limiting the use of phosphorus fertilizers. Goal 2. Achieve water quality standards in lakes, streams, and wetlands consistent with their designated uses and established classifications. Policy 2.1. Manage each water body in the City’s surface water system to meet state, local, and federal water quality standards. Policy 2.2. Require that development and redevelopment projects demonstrate no net increase in the annual mass of total suspended solids (TSS), total phosphorous (TP) from the site compared to pre-development conditions. Policy 2.3. Require owners of development or redevelopment projects to provide on-site volume reduction or treatment or, where volume reduction is infeasible, contribute to the construction or improvement of a regional facility. Policy 2.4. Establish and implement on-going programs for property owners, local leaders, and those who live, work and play in the city designed to promote active stewardship of water resources. Develop and maintain a public education program to promote reduction of nutrient and sediment loading to water bodies. Policy 2.5. Continue to monitor long-term water quality trends on prioritized water bodies. Policy 2.6. Develop and implement a priority ranking scheme to focus management activities and capital improvements. Update priorities annually with a 5 year horizon. Policy 2.7. Evaluate the progress of the surface water management program on an annual basis in conjunction with the NPDES MS4 annual report. Page | 4-5 Local Stormwater Management Plan, December 2018 Policy 2.8. The City may require higher water quality standards in areas draining to an Impaired or Special Water. Policy 2.9. The City will lead by example by following the standards of this Plan and implementing BMPs to provide pollution prevention and water quality treatment on City-initiated projects. Policy 2.10. All vegetative surfaces must utilize native vegetative cover, deep rooted low mow/no mow/turf alternatives, or approved landscape plantings. Landscape plantings include woody vegetation, annual and perennial forbs, ornamental grasses, fruit/vegetable gardens, and mulch Policy 2.11. Prohibit the discharge of foreign material into the storm water system. Such material should include, but not be limited to, waste oil, paint, grass clippings, leaves, commercial fertilizers, trash, construction debris, and miscellaneous chemicals. Policy 2.12. Continue implementing a spill response program for the City personnel to prevent discharge of spilled materials into the storm sewer system. Policy 2.13. Continue to implement the erosion and sediment control policies and the construction site inspection program to ensure reduction of water quality impacts from lack of erosion and sediment control. Policy 2.14. Protect shorelands and water resources. All properties are required to have native vegetated buffer adjacent to wetlands, storm ponds, and water resources. Non- conforming properties, and lots of record shall be brought into compliance when applying for permits or variances to improve the property. Non-conforming buffers should attempt to meet regulatory requirements whenever possible. The minimum non- conforming buffer width shall be 10’. Policy 2.15. Maintain a shoreland ordinance consistent with DNR requirements and recommendations to promote and encourage shoreland protection. Policy 2.16. Develop a Vegetation Management Plan. Ordinances and policies will be updated based on the goals and recommendations of the plan. Wetlands The City of Chanhassen serves as the Local Government Unit (LGU) for the purposes of administering the State of Minnesota’s Wetland Conservation Act (WCA). The City’s Wetland Protection Ordinance sets forth standards for the protection of wetlands, including wetland buffers, setbacks, and mitigation of unavoidable impacts. The policies and strategies set forth in this Plan will apply to all property within the City. Any wetland habitat will be subject to these management policies, as well as the rules and requirements of the Wetland Conservation Act. Goal 3. Protect and rehabilitate wetlands to maintain or improve their function and value. Policy 3.1. Continue to act as the responsible Local Government Unit (LGU) for administration of the Minnesota Wetland Conservation Act (WCA) for wetland impacts in the City. Policy 3.2. Maintain an official wetlands map that classifies wetlands by function and value and periodically update the wetland inventory data and the wetland management classifications. Page | 4-6 Local Stormwater Management Plan, December 2018 Policy 3.3. Update the City’s Wetland Protection Ordinance as necessary to maintain consistency with state and watershed district requirements. Policy 3.4. Promote stewardship of wetlands on private property Policy 3.5. Ensure administrative costs are reasonable and sufficient to cover administration of WCA. Administrative fee will be an average of neighboring LGUs that administer the WCA Policy 3.6. Improve historic wetlands through pre-treatment and restoration activates when practical to do so, and in conjunction with street improvement and redevelopment projects Policy 3.7. Prioritize the protection the Seminary Fen and, unique natural resources during development and redevelopment Policy 3.8. Allow natural wetland systems to function within their existing and historic boundaries without interference or removal of non-invasive plant and wildlife species Policy 3.9. Impacts to, or created by, existing, non-invasive, vegetation and wildlife caused by local climate impact, natural behavior, or approved development are considered natural wetland functions Groundwater The City’s role in managing groundwater resources is limited in scope. There are actions the City can take to prevent or minimize impacts to groundwater quality. Groundwater and surface waters interact, and streams and wetlands and to a lesser extent lakes are reliant on groundwater contributions to maintain stream baseflow and wetland hydrology. The City’s primary strategies in groundwater management are to encourage infiltration of stormwater to help recharge surficial groundwater and to encourage water reuse and conservation to reduce consumption and protect the water supply. Goal 4. Prevent contamination of the aquifers and promote groundwater recharge to maintain base flows in streams and wetlands. Policy 4.1. Continue implementation of the City of Chanhassen Wellhead Protection Plan and implement Carver County Groundwater Plan 2016 Policy 4.2. Cooperate with the Minnesota Department of Health (MDH), Carver County, the Department of Natural Resources, and other agencies to periodically assess the vulnerability of groundwater used for drinking water supplies. Policy 4.3. Promote infiltration of stormwater and resulting groundwater recharge where it is feasible and does not pose a threat to groundwater quality, in accordance with the Minnesota Department of Health’s Evaluating Proposed Storm Water Infiltration Projects in Vulnerable Wellhead Protection Areas. Policy 4.4. Promote proper well abandonment. Page | 4-7 Local Stormwater Management Plan, December 2018 Regulatory Responsibility Regulatory authority for the various WMO’s within the City are shown in Table 4.3. The City assumes the role of permitting all applicable land alteration activities summarized in table 4.3 and enforcing the standards and policies set forth by the LWMPPlan. Riley Purgatory Bluff Creek Watershed District (RPBCWD) also reviews and permits on any proposed land alteration under their rules within the RPBCWD. Minnehaha Creek Watershed District (MCWD) permits for projects that include land alteration, floodplain alteration, dredging, shoreline and streambank improvement, and stream and lake crossings. Lower Minnesota River Watershed District reviews alterations to land within the Minnesota River valley. Carver County Water Management Organization reviews and permits land altering projects in the WMO. The City is the LGU for the Wetland Conservation Act, and assumes the role of permitting all wetland impacts. The Minnesota Department of Natural Resources has authority over issues relating to water and wetlands designated as State Protected Wetlands and Waters. The U.S. Army Corps of Engineers has authority relating to all wetlands identified by the U.S. Fish and Wildlife Service’s National Wetland Inventory. The Minnesota Department of Health has regulatory authority over groundwater issues within the City. Carver County has adopted a Groundwater Plan (2016). Erosion control falls under several jurisdictions including the City, the watershed districts, and the MPCA. The MPCA also has regulatory authority over individual septic systems within the City limits. Table 4.3. Agencies with regulatory authority.

Policy 5.3. This plan and all subsequent amendments will be consistent with the plans of regulatory agencies. Policy 5.4. This plan will be amended as necessary to remain current. Page | 4-8 Local Stormwater Management Plan, December 2018 Policy 5.5. Coordinate projects and information with government agencies; i.e. MnDOT, Carver and Hennepin Counties, Department of Natural Resources, Watershed Districts, and Water Management Organizations. Public Education and Participation The public education and participation goals and policies recognize that people want to be involved in decisions that affect the water resources in their community. The City seeks to create opportunities for the public to participate in information gathering and decision-making. Public education and participation activities are also requirements of the National Pollutant Discharge Elimination System (NPDES) Permit. Goal 6. Cultivate an environmentally literate public to promote an active community role in sustainable management of water resources. Policy 6.1. The City will continue to provide opportunities for public involvement (e.g., neighborhood meetings, public hearings, mailed notices, etc.) for significant water resource decisions or projects. Policy 6.2. The City will coordinate and consult with appropriate City commissions and committees on surface water issues. Policy 6.3. The City will communicate with lake associations and other appropriate civic and citizen groups. Policy 6.4. The City will develop an Education and Outreach Plan, actively implement the current educational programs, and work to develop and implement new education programs and activities related to water resources. Policy 6.5. The City will cooperate with other agencies and encourage establishment of model interpretative sites for public education like the stormwater practices at the Landscape Arboretum. Policy 6.6. Continue to remain in compliance with the NPDES Phase II MS4 permit with respect to public education and involvement. Policy 6.7. Promote the installation of low mow/no mow turf, turf alternatives, and restoration of native vegetation on all public and private property within the city.

Prioritize partnership opportunities with CCWMO to improve and expand education and outreach programs and goals Page | 5-1 Local Stormwater Management Plan, December 2018 5.0 Implementation Plan The City of Chanhassen will implement both management programs and capital projects to achieve the goals and policies set forth in this Plan. These actions address the problems and issues identified here as well as NPDES and TMDL requirements and agency and watershed expectations. The following sections describe those actions, which as summarized in Tables 5.2 and 5.3. Each year the City will review progress and resources, and these implementation actions may be reviewed and updated based on changing conditions or requirements. If necessary, this Plan may be amended in accordance with the procedure set forth in Section 6.0. 5.1 PERMITTING AND ENFORCEMENT Numerous local, state, and federal agencies regulate water resources. However, the primary regulators are the City of Chanhassen; the four watershed management organizations within Chanhassen; the Minnesota Department of Natural Resources (MDNR); and the Minnesota Pollution Control Agency (MPCA). These regulations are discussed in Section 2.0 Regulatory Framework. 5.1.1 Current Ordinances and Potential Revisions The City of Chanhassen has enacted numerous policies and ordinances regulating and managing water resources. These are described in Section 2.1 above. In its NPDES stormwater permit application, the City agreed to within one year or permit approval adopt ordinance revisions as necessary to meet permit requirements. It is the City’s desire to reduce administrative and regulatory burden while staying protective of our water and natural resources. The City intends to exercise sole regulatory authority over development and redevelopment projects requiring stormwater, wetland, floodplain, or erosion control review and approval, and will work with the WMOs to adopt Memoranda of Understanding (MOU) or other similar agreements. The City will continue to ensure submission of applications for permits under those WMO rules, and all variances, for which the city does not have authority are submitted to the WMOs for review and approval. This process will be assured through the implementation of a new water resource permit process developed in collaboration with the WMOs. In addition to amending its official controls the City will follow the framework and scope for each WMO required to adopt an MOU. Specifically, RPBCWD requires the MOU details the scope of each entity’s exercise of regulatory authority (i.e., who will regulate what) for presentation to the City Council and Board of Managers for approval. The MOU also will establish a process and schedule for exchanging progress reports, the city’s submission of permitting information to the District and regular meeting to ensure water-resources management concerns and projects are pursued via the most effective and cost- efficient route possible. The MOU also will provide procedures and a timeline for the District’s reengagement of all of its regulatory authority if the city is found not to have adopted the necessary official controls or implemented a complete and effective regulatory program. Additional regulatory revisions are necessary to bring the ordinances into conformance with the requirements of the WMO’swatershed districts in the city (Table 5.1). The city will undertake these ordinance revisions within six months after adoption of this Plan. It is expected that where the Page | 5-2 Local Stormwater Management Plan, December 2018 requirements of the individual watershed districts differ, the City will adopt the most stringent of the requirements for application citywide. The most stringentCity will adopt and use the current requirements of each WMO for permitting reviews, which are generally summarizedthe City will adopt are highlighted in Table 5.1. The city will work with the WMOs as it considers regulatory revisions and permit review processes and procedures to ensure that they are consistent with WMO requirements. The city commits to updating its ordinances as necessary and required within one year after receiving notification that a WMO has significantly revised its rules and standards.

Page | 5-7 REVIEW DRAFT Local Stormwater Management Plan, January 2018 5.1.2 NPDES Permit Implementation Requirements Under the requirements of NPDES Phase II, the City has implemented a Storm Water Pollution Prevention Program (SWPPP). Best Management Practices (BMPs) identified in the MPCA-approved SWPPP are implemented on an ongoing basis. Annual activities are detailed in the city’s Annual Report and reviewed at an annual public meeting prior to submittal of the annual report to the MPCA. More information about the SWPPP can be found in the Surface Water Resources Section of the City’s website (http://www.ci.chanhassen.mn.us/index.aspx?nid=1085.) The City’s Engineering/GIS Department maintains databases and GIS mapping of stormwater and wetland information for both public and private systems. These sources summarize pertinent management information about BMPs, wetlands, and other water resources in the city including BMP location, type, and responsible party. The information provided for stormwater ponding systems includes physical condition, maintenance histories, pond elevations, watershed acreages, basin sizes, and other as-built information where available. The City utilizes a Stormwater Asset Management Program from WSB to rank basins based on cost/benefit, pollutant removal efficiency, and annual inspect data. All information is being collected, updated, and integrated into the City’s general asset management software on an ongoing basis as part of the NPDES Phase II permit requirements and provides data and direction to prioritize maintenance. The city will work with state, federal, and local entities to determine additional data needs and the best approach to manage the data. An Inventory of real property owned by the City, and maps of public and private stormwater systems are included in Appendix A. The City is committed to complete the MCWD conveyance map and inventory discussion within 2 years of Plan adoption. The State’s General Permit was reissued effective August 1, 2013, and the City has been issued a reauthorized permit. The City’s SWPPP application identified a number of BMPs that the City needs to initiate or update, such as developing certain programs, expanding record keeping, and establishing new or modified policies. The new permit also requires revisions to the city’s ordinances requiring stormwater management, namely adopting more stringent standards to reduce phosphorus and total suspended sediment in stormwater runoff, limiting new volumes of stormwater runoff, public education and staff training, illicit discharge, BMP inspection and maintenance for both public and private stormwater BMPs. 5.2 IMPLEMENTATION PROGRAMS AND PROJECTS 5.2.1 Education and Outreach Program The City recognizes that a critical element in reaching the long-term goals developed for this LWMP is public education. An education and outreach plan will be developed to achieve these goals and meet requirements of the NPDES permit. This plan will incorporate opportunities to collaborate with the four WMOs and other organizations to maximize existing local education resources and expertise. The City also uses various media outlets such as local news articles, City newsletters, Facebook, and the City of Chanhassen website to educate citizens on the basics of our stormwater system, provide updates on current actions the City is taking to monitor or improve stormwater systems, and inform residents about opportunities to improve local water bodies through workshops, volunteer opportunities, or rebates. Page | 5-8 REVIEW DRAFT Local Stormwater Management Plan, January 2018 City events and festivals provide additional opportunities for education. High priority topics are periodically identified for emphasis, including topics such as:  Water resource management  Pollinators and Wildlife habitat  Groundwater protection  Low impact and green design such as pervious pavers  Wetlands  Pet waste control  Native plant establishment  Leaf and grass clipping management  Wetland, lake and pond buffers  Lawn chemical and phosphorus fertilizer usage Adults and youth can also participate in outreach activities such as: the storm drain labelling program; Wetland Health Evaluation Program (WHEP); park cleanup events; Citizen Assisted Lake Monitoring program (CAMP). The City Council relies on a Planning Commission and Environmental Commission to provide recommendations and direction on water resource topics. The City recognizes the important value of coordination and collaboration with other agencies, and will continue to find opportunities to improve these relationships and will utilize collaborative resources such as WaterShed Partners, Blue Thumb, Let’s Keep it Clean, the Minnesota Stormwater Coalition, and the CCWMO to maximize resources and message impacts. LMRWD offers a Cost Share Incentive Program and Water Quality Restoration Program that the city will promote. Education programming includes training for City staff, local leaders and decision makers on various water resources management topics. 5.2.2 Monitoring Program The city will meet with each WMO staff annually to review opportunities to coordinate data collection and assessment to improve informed decision making. In addition the city continues to operate the following monitoring programs: Citizen Assisted Monitoring Program (CAMP). The City of Chanhassen partners with the Metropolitan Council to participate in its Citizen Assisted Monitoring Program (CAMP). Volunteers collect surface water samples from Chanhassen lakes. The samples are then sent to the Metropolitan Council to be analyzed for the following: • Total phosphorus (TP) • Total Kjeldahl nitrogen (TKN) • Chlorophyll-a (CLA) Volunteers also gather the following information: • Measure surface water transparency using a Secchi disc • Record water temperature • Record perceptions such as weather conditions Samples are taken bi-weekly from April through October (14 sampling dates) and are sampled at the lake's deepest open-water location. The CAMP currently monitors the following lakes: • Lake Lucy Page | 5-9 REVIEW DRAFT Local Stormwater Management Plan, January 2018 • Lake Minnewashta • Lake Riley • Lake St. Joe • Lake Susan • Lotus Lake Stream Health Evaluation Program (SHEP). This program gives citizens professional training on how to evaluate a stream health based on physical assessments and bio-monitoring. Citizens evaluate physical characteristics of stream sites, collect and identify macro-invertebrates. Citizens get hands on opportunities to learn about stream ecosystems and assist Carver County in water quality monitoring. Aquatic Invasive Species (AIS). AIS monitoring is coordinated through a partnership program with CCWMO, RPBCWD, and local lake associations 5.2.3 Operations and Maintenance The City of Chanhassen follows Best Management Practices (BMPs) in operating and maintaining its infrastructure and facilities, consistent with its NPDES permit and this Plan. The City’s approach to ensuring maintenance of private stormwater infrastructure for development and redevelopment includes:  Stormwater BMPs are required to be placed into permanent easements recorded against the property  Public BMPs are required to be placed in drainage and utility easements recorded on the plat  All BMPs are required to have Operation and Maintenance Plans detailing maintenance responsibilities, and recorded against the property  All BMPs are required to have Inspection Forms detailing inspection activities and including identification of responsible party performing the maintenance and submitting annual inspection reports  Authorization for the City to access BMPs for inspection and to perform maintenance if property owner fails to meet requirements. Property owner is responsible for all maintenance costs incurred by the City  Wetlands and water resources are to be placed into outlots during development or redevelopment.  Recommends BMPs receiving public or community stormwater not be placed on single family residential lots during development or redevelopment  The City does not have the capacity to take on private stormwater BMP maintenance, therefore, it is the responsibility of the property owner to operate, maintain, and inspect City staff and projects serve as a model for good housekeeping practices. Some specific Best Management Practices integrated into daily activities include: Street Sweeping. The City sweeps all streets at least annually, and sweeps more frequently in certain key areas. Staff continuously reviews street sweeping practices to assure they are consistent with the latest management recommendations. Some TMDLs and UAAs have identified key areas where enhanced sweeping can provide additional nutrient and sediment removal to protect or improve lake and stream water quality. Page | 5-10 REVIEW DRAFT Local Stormwater Management Plan, January 2018 Snow and Ice Control. Street maintenance staff use the recently-developed Winter Maintenance Assessment Tool from the MPCA to evaluate and enhance snow and ice control practices optimizing the application of road salt - sodium chloride – to limit chloride loading to surface waters. BMP Inspections and Maintenance. In accordance with its NPDES permit, stormwater ponds are inspected at least every five years for sediment accumulation and maintenance needs. The City’s BMP Inspection and Maintenance Program ensures public and private stormwater infrastructure is inspected and maintained to meet regulatory requirements. Private stormwater BMPs on sites over an acre that discharge into the City’s system submit annual inspection reports, and are inspected by City staff once every three years. The City utilizes design standard details setting forth the City’s BMP and infrastructure design and maintenance requirements. The City is developing its Stormwater Inventory Inspection and Maintenance Plan. This Plan includes both activities necessary to meet NPDES Phase II permit obligations as well as general operations and maintenance activities. These include:  BMP operation and maintenance plans  Vegetation Management Plan  Facilities Maintenance Plans  Street and parking lot sweeping  Chloride management  Catch basin and sump inspection, cleaning, and repair.  Sump catch basin inspection, cleaning, and repair.  Sediment removal schedules.  Televising, jetting, and repair of storm sewers and culverts.  Treatment effectiveness evaluation.  Illicit discharge detection and elimination plan As a requirement of its NPDES permit, the City must establish Enforcement Response Procedures and Plan Review Checklists which will be added as Appendix D and E within 6 months of Plan adoption. The City of Chanhassen also maintains up to date GIS shapefiles containing information about water bodies, stormwater facilities, and stormwater infrastructure. Opportunistic BMPs. Where possible, Chanhassen will incorporate BMPs into its street and utility infrastructure to protect and preserve its water and natural resources. 5.2.4 Capital Improvement Program The Implementation Plan in Tables 5.2 and 5.3 details a Capital Improvement Program (CIP) of projects. The Use Attainability Analyses (UAAs) and Total Maximum Daily Load (TMDL) studies have identified potential actions that could help protect and improve the water quality in and enjoyment of studied waterbodies, and some of those actions are included. In addition, every year the City considers updates to the City’s CIP not only for improvements to the storm drainage system but also the transportation system, water and sanitary sewer utilities, and park facilities. Drainage system maintenance and condition assessments have identified a number of pond maintenance and other projects such as dredging to restore or enhance the effectiveness of those features, and priority actions have been included in the CIP. Page | 5-11 REVIEW DRAFT Local Stormwater Management Plan, January 2018 Road, utility, and park projects are also an opportunity to incorporate water quality and quantity BMPs. These projects are intended to maximize the amount of nutrient and sediment removal from stormwater prior to being discharged into the lakes, streams, and wetlands in the community. Concept- level planning estimates the cost of potential BMPs for inclusion in the CIP. Specific BMP selection and design are undertaken during project design. The CIP also includes collaborative projects with the watershed districts. The City is open to working together with the districts to identify additional projects or opportunities to integrate water resource and conservation protection, including working with the Minnehaha Creek district in advancing its Balanced Urban Ecology policy. The City also intends to prepare a Natural Resource Management Plan to identify, prioritize, and recommend restoration and management strategies for all public natural areas, and will consult with the various WMOs to obtain their input and feedback. This CIP is reviewed and updated annually, and additional projects may be added as more or better information is available or as opportunities arise. 5.3 IMPLEMENTATION PLAN FUNDING The City will fund the Implementation Program (IP) through a combination of sources. The primary source of funds will be Stormwater Utility Fees. The types of activities included in the IP can be categorized as operations and maintenance; programs and special studies; and capital projects. Operations and maintenance and most of the proposed programs and special studies would be funded by the Stormwater Utility,and/or the General Fund, or the Water Surcharge Fund. For capital projects, other sources of funding may be available to supplement Stormwater Utility Funds: matching funds from the watershed districts, contributions from other agencies for cooperative projects, or grant funds.

Page | 5-15 REVIEW DRAFT Local Stormwater Management Plan, January 2018 5.4 ADDRESSING IDENTIFIED PROBLEMS AND ISSUES As noted earlier in Table 3.2 of this Plan, the planning process revealed a number of problems and issues. Table 5.4 repeats those by category, and describes how each was addressed in this Plan. Table 5.4. Implementation actions addressing identified problems and issues. Category Identified Problems and Issues Identified Solutions Water Quality Conditions Lakes and streams are listed on the Clean Water Act Section 303(d) TMDL List of Impaired Waters. The CIP includes, and will periodically be updated to include, projects to achieve pollutant load and runoff volume reductions to address listed impairments and NPDES permit requirements. Nonpoint source pollution reduction is necessary through maintenance practices such as street sweeping, sump manhole cleaning, and BMP inspections. The City has an ongoing program of routine and targeted street sweeping and sump manhole cleaning. Public BMPs will continue to be systematically inspected. Maintenance activities and projects programmed into the CIP. Drainage and Flooding Near stream gullies and escarpments should be addressed to control sediment deposition into surface waters and to protect property and infrastructure. The City will continue to work with WMOs to protect existing and improve flood storage capacity through targeted BMPs and increased street sweeping. The City will prioritize BMPs that protect or repair highly erodible and sensitive soil areas in the Bluff Creek Overlay District. Regulatory Requirements and Operational Policies Atlas 14 updated precipitation frequency data is available for adoption. The City will require stormwater modeling work to use Atlas 14 precipitation depths and nested distributions. Approaches such as Minimal Impact Development and Integrated Management Practices are available to reduce the public expenditures necessary to control runoff and protect and improve water quality. The City will continue to work with developers to incorporate standards into new development and redevelopment. The City’s approved NPDES permit and SWPPP requires ordinance revisions and operating program enhancements. City Code will be revised within 12 months to incorporate volume management and water quality requirements. City goals, policies and ordinances to help protect natural resources may need review and refinement. The City currently has ordinances in place protecting steep slopes and bluffs, shorelands, wetlands, and the Bluff Creek Overlay District Water-Based Recreation Needs Water quality should be protected and improved to protect and enhance recreational opportunities. This Plan includes a number of capital projects and maintenance programs intended to improve water quality to better support fishing, swimming and boating. Control of aquatic invasive species (AIS) continues to be an important concern The City will continue to work with CCWMO, watershed districts, lake associations, and DNR to undertake AIS program activities such as watercraft inspections, biocontrol, fish restocking, or other similar activities. Maintenance Requirements BMP maintenance and repair requirements have been identified during NPDES The City will continue to systematically assess the condition of public BMPs. The CIP includes Page | 5-16 REVIEW DRAFT Local Stormwater Management Plan, January 2018 Category Identified Problems and Issues Identified Solutions inspections, including restoration of storage capacity, repair of erosion, and prevention of future problems. and will periodically be updated to include projects identified in the pond inventory and inspections. Street sweeping, sump manhole cleaning, and BMP inspections are necessary on an ongoing basis to help reduce nonpoint source pollutant loads. The maintenance program includes provisions for regular and special street sweeping; inspection and maintenance of sump manholes and catch basins; basin inspections and repairs; illicit discharge detection; and erosion control. Education and Outreach Education and outreach efforts could be expanded with a focus on targeted groups with new and expanded educational opportunities. Opportunities exist with CCWMO and other organizations to improve efficiency and reduce duplication of efforts Education and outreach efforts will be continued including written and electronic communications, and opportunities for participation by citizen volunteers such as the Wetland Health Evaluation Program (WHEP) and the Citizen Assisted Monitoring Program (CAMP) for lakes. Increase collaboration and coordination with CCWMO and other organizations Financial Resources Financial resources are limited, requiring that projects be prioritized. The budget in this Plan prioritizes operating programs and projects to address both regulatory and operational needs and water resource improvements. The City will continue to leverage available funding by collaborating with partners and seeking grant funding. Groundwater Protection The LWMP should be coordinated with the Wellhead Protection Program and Carver County Groundwater Plan (2016) so that policies that encourage infiltration and groundwater recharge are consistent with the policies to protect sensitive groundwater recharge areas Infiltration requirements are integrated with Wellhead Protection requirements and Carver County Groundwater Plan (2016) to protect groundwater quality. Seminary Fen is a rare calcareous fen and Assumption Creek is a trout stream, both of which are dependent on groundwater. The City participates in the Met Council’s Seminary Fen Work Group to study the effects of groundwater pumping on Seminary Fen. City ordinance imposes stringent standards on development and redevelopment in the Assumption Creek drainage area. Collaboration Opportunities There are opportunities for collaboration with other agencies such as the watershed districts, the Three Rivers Regional Park District, and state agencies to leverage expertise and resources to finance and construct improvements. The City will continue to collaborate with the watershed districts to identify and complete capital projects and pursue opportunities with development and redevelopment projects.

PUBLIC HEARING: CONSIDER A REQUEST FOR APPROVAL OF THE SUBDIVISION OF 6.4 ACRES INTO TWO SINGLE-FAMILY LOTS WITH VARIANCES FOR PROPERTY LOCATED AT 1641 WEST 63RD STREET (NYE ADDITION). Planning Commission Summary – May 5, 2020 2 Sharmeen Al-Jaff and Erik Henricksen presented the staff report on this item. Commissioner McGonagill asked if the cul-de-sac radius was adequate for fire truck maneuvers, the cul-de-sac length versus city code requirements, clarification regarding the sanitary sewer, and the narrow right-of-way between Wood Duck Lane and Yosemite. Commissioner Randall recused himself from this discussion due to a conflict of interest. Commissioner Reeder asked if this road connection is shown in the Comprehensive Plan and if a ghost plat was created with the Pheasant Hill plat showing how this plat affects development of the parcel at 6480 Yosemite. Commissioner Noyes asked if the Outlot A wetland would be affected if the road connection goes in in the future. Speaking on behalf of the applicant Ann Nye, Woody Love described their thought process in developing this parcel of land and noted he was available to answer questions. Chairman Weick opened the public hearing. Sharmeen Al-Jaff summarized the information contained in emails sent to the City regarding this item. A number of individuals living on Wood Duck Lane do not want to see this connection happen as they don’t want to see the through traffic and the intent is to keep the neighborhood as is. Neighbors on 63rd Street were in favor of the road connection as a means to take some of the traffic off of their street. City staff received an email today expressing support of the project and noted that some of the signatures on the petition to save Wood Duck Lane did not live in Chanhassen. Jay Meyer, 1611 West 63rd Street and the neighbor to the east of Ann Nye, asked for clarification on the status of the wetland and road connection if development occurs in the future and expressed favoring putting in a trail over the right-of-way.

Weick: Well thank you very much Eric and welcome to the Planning Commission and we look forward to working with you. Second new to the Planning Commission for the next term is Mark Von Oven. If you could also introduce yourself Mark. Von Oven: Hey everybody, Mark Von Oven. Really excited to be here. My wife and I have lived here in Chanhassen for the last 3 years. We have a 5 year old daughter and two 3 year old sons so if finding a quiet place for a Zoom meeting version of the Planning Commission was a requirement I don’t think I would have made it on the Planning Commission so I apologize when the kids all run in and jump on top of me during the middle of the meeting but really excited to be here and excited to meet all of you in person. Chanhassen Planning Commission – May 5, 2020 2 Weick: Yep and we’re excited to have you as well. Welcome and again look forward to working with you as well Mark. No matter what’s in the background. Again tonight’s meeting is a little out of the ordinary for us so I’d like to review the guidelines that we will have for this meeting and just take a few minutes to walk through that. This is our first Planning Commission attempt at this so we do ask for everybody’s patience. Also that the commission members not hold chats or discussions on the side through the Zoom application as all discussions need to be made public. Tonight we have two public hearings on tonight’s agenda and we will do our best to follow the following format. Staff will present the item. At that time we will ask for comments from the Planning Commission. The applicant will then be asked if they would like to make any additions or comments on behalf of their petition. At that time then we will open the public hearing. For the public hearing there are a couple different ways to join. All emails will be summarized and read for the record. Any that have been submitted. If there are any in person comments they’ll be taken here in the council chambers and we are practicing safe social distancing. And the third way is for telephone calls and calls will be taken and the phone number will appear on your screen at the time that the public hearing is opened for comments so you can call in as well. Once we’ve heard, and we’ll take some extra time there to make sure that we have the opportunity to hear from everybody that wants to be heard through whatever channel they choose. At that time we’ll close the public hearing and the commissioners will then have another chance to discuss the item. At that time I think it might work best to go, we’ll call on commissioners to make their comments so that we’re not just talking over the top of each other. We’ll see how that works and then we’ll need a motion, a second and we will take a roll call vote so I will, I’ll call your name and you will vote either yay or nay for the item. With that I will introduce the first item on the agenda this evening. PUBLIC HEARING: CONSIDER A REQUEST TO AMEND THE PUD AT 7801 AUDUBON ROAD (PAISLEY PARK). Weick: Kate we have a request to amend the PUD at 7801 Audubon Road which is Paisley Park and that is Case No. 2020-04. With that I will turn it over to you Kate. Aanenson: I’m just looking for the screen to come on. The power point. Awesome, thank you. Thank you Chair. Good job on the announcements. So this item will be going to City Council on May 26th so this is a request to amend the ordinance governing Paisley Park to allow for unlimited smaller events and up to 12 larger events and one outdoor event per year. As you’re aware Paisley Park is located on Audubon Road just off of Highway 5. In your staff report there was a lot of detail regarding the background on this and I just want to remind everybody what the background was especially for our new Planning Commission members. So back in October of 2016 the Planning Commission chose to make this a PUD which would allow for museum tours and concerts affiliated with the park. Because the property was zoned office industrial, and that’s how the recording studio was being used, the PUD was the tool then to implement how the property was to be used. So in 2018 they also asked to allow for alcohol for special events. I think the first test might have been some of the Super Bowl events and the like so and that has Chanhassen Planning Commission – May 5, 2020 3 gone very well. So then we also amended it to do for all temporary, for a number of temporary events. Not all temporary events so that was amended in 2019. So since that time there’s a new Executive Director and I’ll let him speak in a minute here but they’re looking at some potential amendments to, as I stated to allow for more smaller events instead of limiting it to the 12 which was the original PUD. So the Executive Manager, or Executive Director Alan Seiffert met with the City Council in January-February to discuss those desires so here we are today to process that request. So again it’s permitted 12 indoor concerts but the calendar year requires a concert specific seating plan and that’s really to make sure the Fire Marshal reviews that depending on the size of the event. So alcohol can be served only in conjunction with the temporary event permit and that’s all through catering because they don’t have a liquor license and no outdoor events. We have had no problems up there and with the sheriff’s office and traffic again a lot of the parking then is off site and they’re bused in or Ubered or the like or Lyft so the proposed change then would allow up to 12 indoor concerts with over 200 attendees. They still would have to do a specific seating plan for those but then allow unlimited private events. So sometimes they will have corporate events. School events and the like so again we, as long as they are following the fire department fire code issues we don’t have a problem with that so we removed the provision requiring the temporary event permit to serve alcohol as long as they’re getting the catering license we would follow through on that. So that would allow potentially one outdoor concert per year. That’s what they’re talking about. Now I’m not sure this year will come to fruition but that’s also something that we would work between the different departments managing traffic, safety and all those issues too so there would have to be a protocol and a plan put in place for that to move forward. So again as I stated to date there’s been no issues with the alcohol service on site and we don’t feel like the smaller events require the level of review associated with the permit and based on the A-3 occupancy the HVAC capacity, the heating ventilating and potential parking issues don’t necessitate a cap on the larger events and justifying requiring permits so some of the concerns that the outdoor events might be an attractive nuisance so again that’s something that we would look at further refinement if they were to come in for an outdoor concert. So we are recommending approval of the amended language is one of the attachments in your staff report so with that following our protocol there I would let you ask if the commission has any questions and I know Mr. Seiffert’s on the Zoom too. Weick: Okay thank you Kate. I would at this time open it for any planning commissioners who would like to ask Kate questions or need clarification. McGonagill: Steve you want to go down the line or you just want us to go individually? Weick: For this one I was just going to let you jump in. McGonagill: Okay I guess the only question I have on this Kate is the last meeting or a couple weeks before we approved The Moments of Chanhassen which is across Highway 5 from this and the only concern I have is, was that senior citizen area there, an outdoor concert at Paisley Park. The impact that that would have on the residents. I realize that they have to kill, or they Chanhassen Planning Commission – May 5, 2020 4 have to turn off their loud speakers at 10:00 but as we know in places like that people retire a lot earlier than that and so did you all consider that or talk to Paisley Park about that? Aanenson: Yep and I’ll let the Executive Director talk about that more specifically but we’re saying that’s a potential. There’s still a lot of logistics to work through. Some of that being that it’s next to MnDOT. Highway 5 and then congestion and traffic because they’re getting bused there or you know there’s not that much parking on site because it’d be a much larger event, some of those things would have to come into play so it’s not a given. They’d still have to have a workable plan before it could be approved but we’re saying the potential is there. McGonagill: So for that, for that permit to be approved would it go to City Council or just to staff? How does that process, let’s say we approve the PUD tonight and they want to do an outdoor event and let’s say there’s concerns like I mentioned for example with The Moments of Chanhassen, how, what form does that come up in? Aanenson: So that’s part of the event permitting. So again that goes to, that would be engineering or else it’d be the fire department, planning. That’s what MacKenzie works on and of course anybody else that would have, the sheriff’s office also weighs in on those too and so if it can’t meet the satisfaction of safety for those departments then it would not be approved just like any other temporary permit. McGonagill: Thank you. Weick: Thank you Commissioner McGonagill. Any other commissioner comments at this time? Skistad: This is Laura Skistad and I just had a question on parking and how that would work if you know would they ever utilize Lake Ann Park during…with busing in or. Aanenson: That’s a great question. They were asked that too and because we have so many summer activities I’m not sure that would be a decision of the Park Director but I think there were some concerns too people going across underneath the tunnel. Whether they would try to go, cross above grade instead of under the tunnel so those, that’s a good question but those are some of the logistics that we would want more details on and how they would manage that. So again these are things that we said we need to understand that that would work so they’d have to still get approval for that permit. Skistad: Okay. And then my only other question was the HVAC system not designed for A-1 occupancy so what are the risks in that? Aanenson: Well it’s just as a limited capacity of how many people they can have in there so as they have a certain number of people inside and number of times that that at some point needs to be upgraded. But if it’s an outdoor concert it wouldn’t affect that but they also have provided for Chanhassen Planning Commission – May 5, 2020 5 restrooms and the like anything else that would be associated with that. Again those are some of the logistics that they need to demonstrate. Skistad: Okay thank you. Weick: Thank you Commissioner Skistad. Other comments for Kate? And hearing none from the other commissioners. Aanenson: Yep so Alan Seiffert I saw him on the Zoom earlier so he’s the Executive Director out at Paisley so if you want to just make any comments Alan. Alan Seiffert: First of all thank you. I think Kate laid it out very well. We are really interested in working very closely with the City just to make sure that whatever we do is going to be successful, not just in terms of what happens at Paisley but for the overall community. We feel that, that after really in the last 6 months in particular, we’ve been spending a lot of time really trying to work with Kate and the team just to make sure as we, as a business grow in scale that we do it in a way that is mindful. We do think we have some great solutions for outdoor but as I think Kate mentioned we will…and we will only move forward in there where all of us feel, whether it’s the City, you know Fire Chief, Carver County whether we all feel comfortable with it. Yes we are aware of the local residents. We are aware of whatever we do outside would impact and so as I said we do have some thoughts about how to best indicate that. Just to be clear we’re talking about outdoor you know, this is Paisley Park. We are not hoping to kind of create some you know extra loud festival. This is really about kind of enhancing the overall experience and we think giving a bit more visibility to Chanhassen and to Paisley so we’re really pleased. We think this is a thoughtful approach and we are, we very much appreciate it. Aanenson: So again we are recommending approval, just as Mr. Seiffert said, you know we’ve kind of taken baby steps through this whole process and kind of building on success and that’s where we want to continue to go. Weick: Great. Aanenson: So I do have a motion. I’m assuming they can see that if the screen is up, the motion. Weick: Everybody in the public. Aanenson: Yep, oh let me just on that too. I did not receive any comments or emails on this item and it was noticed so. Weick: So at this time we will open the public hearing. As Kate mentioned there are no emails to be summarized for the record. I would certainly invite anyone here in person who wishes to Chanhassen Planning Commission – May 5, 2020 6 speak on this item to come forward. Seeing no one come forward in person, I guess we’d see if there’s telephone calls. Aanenson: We don’t have any. Weick: And we don’t, we don’t have. So we will give that a minute. See if anyone attempts to dial in. While we’re waiting I will say it’s exciting to have a place like Paisley Park I think in our city as Mr. Seiffert mentioned. It’s a very nice you know addition and public attraction, museum and event space that’s very unique and I think very special for Chanhassen so we are pleased to have them as neighbors. So did not hear any phone calls, no one called in so I’m going to assume that we don’t have any of those either and I will close the public hearing portion of this item. At this time our Planning Commissioners can make comment. I will go around the table for those comments at this time. I’ll call you out by name and if you want to make any special comments or ask any final questions you may do so at that time. Once we’ve gone through each commissioner then we could consider a motion and a second. So I’ll start with Commissioner Randall. Any comments or questions? Randall: I do not have any comments or questions. I just think it’s a good move and I’ll be voting in favor of it. Weick: Great, thank you Commissioner Randall. Commissioner Reeder. Any comments or questions? Reeder: I have no comments at this time. I see no problem with what they’re proposing. Weick: Thank you. Commissioner Noyes? Noyes: I don’t have any questions or comments at this time either and I’m very supportive as well. Weick: Thank you. Commissioner McGonagill? McGonagill: I don’t have any comments Chairman and I do appreciate Paisley Park’s approach to this and working with the City and just continue to be thoughtful as you step through it and I know you’ll continue to grow and that’s what we want so I will be voting in favor as well. Weick: Thank you. And Commissioner Skistad. Skistad: My only comments is they have been good neighbors and I’ve had good neighbor conversations with many of my neighbors as well and we like what’s going on there so I will also be voting in favor of this. Weick: Thank you. That’s a good perspective. And finally Commissioner Von Oven. Chanhassen Planning Commission – May 5, 2020 7 Von Oven: Again no questions just that Paisley is a very special place in our community and I’m happy to vote in favor. Weick: Wonderful. So at this time we can consider a motion. It’s in your packet or on the screen. Randall: I’d like to make a motion. Can you hear me? Weick: Yep go ahead. Randall: Yeah I’d like to make a motion. Weick: Okay. Randall: The Chanhassen Planning Commission recommends that the City Council approve the proposed amendments to Paisley Park’s Planned Unit Development (PUD) ordinance. Weick: Thank you Commissioner Randall. We have a valid motion. Do we have a second? McGonagill: I’ll second it. Weick: We have a second from Commissioner McGonagill and at this time I will take a roll call vote on the item. Randall moved, McGonagill seconded that the Chanhassen Planning Commission recommends that the City Council approve the proposed amendments to Paisley Park’s Planned Unit Development (PUD) ordinance. All voted in favor and the motion carried unanimously with a vote of 7 to 0. Weick: So we have a majority. 7-nothing unanimous vote in favor of amending the PUD for Paisley Park. Thank you Kate. PUBLIC HEARING: CONSIDER A REQUEST FOR APPROVAL OF THE SUBDIVISION OF 6.4 ACRES INTO TWO SINGLE-FAMILY LOTS WITH VARIANCES FOR PROPERTY LOCATED AT 1641 WEST 63RD STREET (NYE ADDITION). Weick: This is Planning Case 2020-06. We will follow the same format and with that I will turn it over to Sharmeen for our staff presentation. Al-Jaff: Chairman Weick, members of the Planning Commission. The application before you is for. Chanhassen Planning Commission – May 5, 2020 8 McGonagill: Chairman can Sharmeen speak up a little bit? She’s coming in very faint. Al-Jaff: Okay is this better? Skistad: Yes. Al-Jaff: Okay. The site is located north of Wood Duck Lane, south of West 63rd Street. West of Yosemite Avenue. The application before you is for a subdivision of 6.4 acres into two lots. Lot 1 contains a single family home as well as multiple accessory structures. Lot 2 is proposed to house a single family home, a future single family home. One of the things that we need to point out the parcels are zoned single family residential. Guided low density and one of the issues that we looked at with Lot 2 is the fact that the city code requires the construction of a primary structure before the construction of a secondary or an accessory use. With this subdivision there will be a small shed that will be located on the site and that will create a non-conforming use. Staff is recommending that the applicant provide the City with an escrow and guarantee that the structure, this accessory structure will be removed within 4 months after approval of this application. Both lots meet the minimum area, width and depth requirements of the zoning ordinance. The proposal is consistent with the Comprehensive Plan and the zoning ordinance and at this point I would like to turn it over to Erik Henricksen, the project engineer to address a few engineering issues. Henricksen: Thank you Sharmeen. Chairman and commissioners, as we have a few new commissioners I would like to introduce myself. My name’s Erik Henricksen. I’m the project engineer as Sharmeen said for the City’s engineering department. Tonight I will be reviewing with you access, right-of-way, utilities, and other engineering and public works related topics associated with the proposed Nye Addition beginning with access. The proposed subdivision has frontage on both 63rd Street to the north and Wood Duck Lane to the south. Lot 1 will maintain existing driveway connection to 63rd Street and the newly created Lot 2 will connect with a new driveway access to Wood Duck Lane. I would like to mention at this time that you will notice a majority of the slides focus on the area near Lot 2 as this is where all the improvements are proposed. Lot 1 has an existing structure with existing services and the preliminary plans provided, they have no improvements proposed on Lot 1 so with that we can move to the next slide. The proposed plat illustrates the dedication of public right-of-way for the potential future extension of Wood Duck Lane to Yosemite Avenue. The dedicated portion of public right-of- way will be adequate to achieve a consistent 50 foot wide right-of-way throughout the corridor which matches the right-of-way widths surrounding the streets such as 63rd Street and Wood Duck Lane. This corridor has been planned connection since the 1980’s since the construction of Wood Duck Lane’s cul-de-sac was built to be temporary. Thus this right-of-way dedication will help achieve the potential connection in the future as development occurs. Next slide Sharmeen. Thank you. Speaking of the cul-de-sac improvements the applicant is proposing to reconstruct the temporary cul-de-sac at the end of Wood Duck Lane. This will bring it into conformance with city standards and city ordinances. The temporary cul-de-sac standard requires the diameter Chanhassen Planning Commission – May 5, 2020 9 of 70 feet. Because the cul-de-sac is located in the area with significant grade change to the north and one existing driveway access to the south the applicant’s engineer did propose a modified temporary cul-de-sac. Now staff did review the modified design and based on the preliminary design the proposed modifications are acceptable because they do meet the intent of what city standards for a temp cul-de-sac is which is to allow emergency service vehicles more maneuverability and they’re designed also to maintain the existing driveway access alignment to the south for if the street is extended in the future. Yeah we can go to the next slide. Looking at services and utilities in the area the proposed subdivision has access to public sanitary sewer and water located in both the abutting rights-of-way. The existing home on Lot 1 currently as I mentioned has active sanitary sewer and water services. Those are had from 63rd Street to the north. Lot 2 however will require new services to be tapped from sanitary and watermains which would be had from Wood Duck Lane right-of-way to the south. While the existing watermain has adequate frontage for the service tap it does continue down the right-of-way loop. The sanitary sewer would require an extension of the existing. So as you can see from the table there the proposed sanitary sewer main is to be extended approximately 150 feet to the east to adequately serve the property. The applicant did show and their engineer’s came up with the design within the preliminary plans to show the feasibility of this extension and the general conformity to city standards and specifications and detail plates and the such. This extended public sanitary sewer main after it is accepted by City Council will be owned and maintained by the City so it will remain a public survey. To the next slide Sharmeen. Thank you. The wetland, there is a wetland. The wetland’s located on Lot 2. It was delineated by Alliant Engineering in the fall of 2019 but delineation and classification subsequently made approved by the City. The applicant has proposed the dedication of Outlot A to the City which encompasses the wetland in it’s entirety. Entire delineated wetland. Summarizing city code an outlot is defined as a platted lot that can’t be developed and in this case it is being dedicated to the City for the protection and preservation of the wetland. Staff does recommend extending the boundaries of Outlot A to incorporate the wetland buffer for additional protection as it won’t impact the constructability of the site. While there are additional wetlands within this subdivision on Lot 1, which is located on the western portion of Lot 1 but these wetlands have already been encumbered by drainage and utility easements back in 2006 and they are being maintained. From what the applicant is proposing impacts to the wetlands on either Lot 1 or 2. So with that I can hand it back to you Sharmeen. Al-Jaff: With this application the applicants submitted a landscape and tree preservation inventory of the site. As you can see the only area that will be disturbed is where the new house pad is going to be. As well as the segment that will bring the cul-de-sac into compliance with city ordinances. The City’s Comprehensive Park Plan calls for a neighborhood park to be located within half a mile of every residence within the city. The Nye Addition has access to both Pheasant Hill Park as well as Curry Farms Park. Staff is recommending approval of this application with conditions outlined in the staff report as well as adoption of the Findings of Fact and Decision Recommendation and we’ll be happy to answer any questions. Chanhassen Planning Commission – May 5, 2020 10 Weick: Thank you Sharmeen and for this round of staff questions I think we will sort of, I’ll call on commissioners if you would like to ask questions of either Sharmeen or Erik, you can do so and just try and have those ready when you are called on. With that I would ask Commissioner McGonagill if you have questions or comments for City. McGonagill: Thanks Chairman. Sharmeen could you put up the map please or Erik, one of them so we can talk through it. Can you do that? Weick: I mean we’re going to try and do that. McGonagill: Okay. Weick: It’s hard to bounce those back and forth but yeah there we go. McGonagill: Back up the one you just had before that if you can. Yeah that’s fine. That one’s fine. So first question, Erik we’ve had this come up before on cul-de-sacs on some things. That cul-de-sac even though it’s kind of a modified plan that will allow the fire trucks to make the turn to come around. I mean the fire department has signed off on this is that correct? Henricksen: Eric has reviewed the plans. The modified cul-de-sac it does maintain that 70 foot radius which, you know for that maneuver so this as you can see what’s important to kind of note too is that from the previous temporary cul-de-sac which is highlighted in brown and then what they’re proposing, that extension I think gives that adequate movement so the short answer is yes but you can see it’s quite an up size from what’s currently there. McGonagill: Correct, yeah it just allows them to come around and make the turn and there’s nothing in the middle of that cul-de-sac. There’s no structure or flower plants or anything like that. Henricksen: Correct. McGonagill: On, and so how far is it, remind me from the main road to this? Is that a 1,900 foot cul-de-sac basically? Henricksen: That’s correct yes. McGonagill: And the city code allows how much? Henricksen: City code last was amended and I believe right now the temporary, or the longest a cul-de-sac can be I believe is 750 feet. I think it used to be 800 and then it went down to 750. McGonagill: Okay so this is quite a bit longer. This one’s quite a bit longer. It will still be quite a bit longer than the code. Chanhassen Planning Commission – May 5, 2020 11 Henricksen: Correct. McGonagill: Where is, this is more of a technical question. I’m just curious from fire prevention again and then I’ll finish on the fire prevention piece. Where are the main fire hydrants up in here? Are they, is there one over on, go ahead. Can you show me? Henricksen: Yeah actually I’m going to try this. We were successfully able to do this before. I’m going to show you my screen so. McGonagill: I can see the red dots so you’re good. Henricksen: Can you see now our datalink? McGonagill: Yes. You’re muted Erik. Henricksen: Okay can you hear me now? McGonagill: Yes. Henricksen: So here is Lot 1 or the potential Lot 1. The existing structure. Right here is Wood Duck Lane so this is that undersized temporary cul-de-sac as it stands now. This symbol right here illustrates the hydrant for access to Lot, which would be utilized for Lot 2 if there was an emergency there. The hydrant over here by 63rd and Audubon Circle is also fairly close to Lot 1 so adequate spacing for fire hydrants per ordinance and fire code are available. McGonagill: So what that means is there’s a, which is good if there’s a fire on Wood Duck Lane or in those homes around those 3 cul-de-sacs, if in the winter the trucks won’t have to run lines that far. They can be there and do what they need to do. Henricksen: Correct and the spacing, the fire hydrant spacing is up to city ordinance and fire code, yep. Right. McGonagill: What size, I’m going to sewer now Erik. What size of sewer main are we running on the extension because there are, there is tracts of land to the, I’ll kind of try to do it. To the east that could at some time be subdivided. They’ll either, the sewer will either go to Yosemite or it will come this way so. Henricksen: The minimum sewer main diameter is 8 inch for the public mains and currently within Wood Duck Lane it is a 8 inch so it’d be an extension of the minimum. The 8 inch PVC sanitary sewer. Chanhassen Planning Commission – May 5, 2020 12 McGonagill: And there’s no, we don’t need a left station or anything back up in there even though there’s a little bit of an undulation? Henricksen: The applicant’s engineer did provide us with preliminary construction plans for it and it is gravity fed at this time. McGonagill: Okay. And then if you can Erik talk about with me a little bit the other side of Wood Duck Lane and Yosemite, there’s a narrow right-of-way there. They’re dedicating a right-of-way south of the outlot and then take me through over to Yosemite. I believe that’s a private drive? Henricksen: That right-of-way is, that section of right-of-way that you’re describing past the Wood Duck Lane is encumbered by a private drive access. The dedication that the applicant is proposing for right-of-way would line up with and create a 50 foot wide right-of-way corridor. Now…is not our typical right-of-way width. 60 foot is and that’s what we maintain for any new subdivision coming in. When we experience these smaller right-of-way widths in these types of neighborhoods it’s better just to keep it consistent rather than trying to keep pushing it out. And 50 foot would be adequate to put in the street section. Required residential street section through our standard specs. McGonagill: So if I go from the right side of outlot A where that 50 foot easement now would be added in to Yosemite, how long is that distance? Henricksen: Could you repeat that question please? McGonagill: Okay if you go from right there to Yosemite down the Tacoma trail, that 50 foot, if it went how far is that? Roughly speaking. Aanenson: About 300 feet. Henricksen: 250 feet. McGonagill: 250 feet? Henricksen: Correct. McGonagill: Okay thank you. Outside of that there is no other non-conformances with this correct? Aanenson: Did you have a question? Can you repeat that? McGonagill: I just had a question Kate. Outside of this area of the right-of-way and the shed there’s really no other non-conformances with this. You know you’ll have the right kind of cul- Chanhassen Planning Commission – May 5, 2020 13 de-sac. You’ll have, there’s a narrow right-of-way here but outside of that everything else is, lines up with the Comprehensive Plan is that correct? Aanenson: Right I mean, it’s not, it’s meeting the requirements and so we’re taking additional right-of-way to provide for potential in the future which is what we always try to do. McGonagill: Okay thank you. That answers my questions. Mr. Chair I’m complete. Thank you. Weick: Sure thing and I will just sort of, once we go through everybody I will give you a chance is something pops back into your head. Commissioner Skistad, questions or comments for City. Skistad: I think Michael covered it. Weick: Okay. Skistad: So I don’t have anymore, thank you. Weick: Great thank you. Commissioner Von Oven? Von Oven: I do not have any additional questions. Weick: Thank you. Commissioner Randall? Randall: I would like to recuse myself from this discussion just because I, I live right next to that area so, is that a problem? Aanenson: You certainly can recuse yourself if you want to. Weick: I will not call on you again. Randall: Sorry about that. Weick: That’s okay. Commissioner Reeder? Reeder: Mr. Chairman a couple questions. What is the, does the Comprehensive Plan call for this road to go back out and connect as we’re allowing? Aanenson: Does it show on the Comprehensive Plan? They don’t show local streets like that. The connections. We only show areas where they’re deficient like a minor collector or something like that so. Chanhassen Planning Commission – May 5, 2020 14 Reeder: Okay second thing when Pheasant Hill was platted was there a ghost plat created at that time to show how the property at 6480 Yosemite would be platted later? Al-Jaff: There wasn’t a plat for it. However over the last I want to say 15 or 20 years there was multiple sketches done, scenarios to look at how that site would develop in the future. Reeder: Can you show up on the screen that property and show me what those choices are? Al-Jaff: Well this is the site right. Aanenson: I think it’d be helpful if you put the datalink up. It’s really hard to see. Al-Jaff: Erik can you please put the datalink up? Henricksen: Sure yeah. You won’t be able to control it. To be honest I don’t have the knowledge of what the division would look like. If you want to guide me through it I’d be happy to. Aanenson: I just wanted to make sure everybody understands what piece of property we’re talking about. Henricksen: Okay yeah I’ll bring that up. Aanenson: Thank you. So where he’s drawing that’s one home with a long driveway that goes out to Yosemite. There you go. Thank you. Al-Jaff: So this parcel has the potential for, currently it contains a single family home but has the potential for 3 additional single family homes. Reeder: And where would they be? Al-Jaff: They would be located along the west portion of the site. Aanenson: Does that include a public street Sharmeen? Al-Jaff: That includes a public street. Reeder: Okay so my question is how does the plat that we’re looking at tonight affect the future development of that property? Al-Jaff: What this plat is doing is dedicating the right-of-way as well as extending sewer service to the site so that should that parcel ever subdivide they would be able to extend services and infrastructure to accommodate the development. Chanhassen Planning Commission – May 5, 2020 15 Reeder: So what they’re meeting or doing this plat, this other property would be able to get water and sewer if it wanted to develop, is that what you’re saying? Al-Jaff: So water is available to the site at this time and maybe Erik if you, yes. Where Erik is pointing the arrow on the site. Sewer will be extended to the, from the cul-de-sac to the east and it will be brought all the way to the most westerly lot line of the parcel we are looking at. Reeder: What about access to those lots? I don’t think you have 50 feet of right-of-way there. You’ve only got 33 is that correct? Al-Jaff: You are correct in saying that and that is one of the things that would have to be secured by the owner of the property. To make the development viable. Reeder: In the email that we got from that owner he’s suggesting that with only limited right- of-way that he would need to have a private road in there constructed on their 33 feet that’s available. Is something we would allow? Aanenson: That would require a variance and then they have to go through their test. It’s hard to see because it’s moving around a lot so you know we’re dedicating right-of-way to the north so I think if we could go back to that slide. So there is some dedication to the north but if it was to development without a public street then it would be whether or not you would allow a private street and that, a private street does require a variance. Up to 4 homes. Reeder: Have we done that in other areas? Aanenson: Sure. Reeder: I mean I live on a street that’s far less than standard. Aanenson: Correct. So if you go back, unfortunately we don’t have it up but there’s pinch point coming out where the driveway goes now. Just someone has to buy some property from one of the homes that are abutting Yosemite and that’s, herein lies the problem to connect that street right now. Reeder: I’m sorry I didn’t understand. It’s not connected up to Yosemite? Aanenson: The driveway comes through there but it’s not a full right-of-way. 50 foot right-of- way. Reeder: It’s 33 right? Chanhassen Planning Commission – May 5, 2020 16 Al-Jaff: So right now there is a driveway over a 33 foot right-of-way that provides access to this parcel and you can see it if you look right here. This is the 33 feet. Reeder: Excuse me. Al-Jaff: And this portion is where we are going to be able to the additional right-of-way right here. And achieve the 50 foot to align. Reeder: If we proceed with this plat it’s logical that your, the only access to that other parcel for development would be off of Yosemite on either acquiring more right-of-way or on a private road with less right-of-way. Al-Jaff: Well. Reeder: Because you’re putting in a cul-de-sac and I suppose you could take that cul-de-sac out is that your theory? Al-Jaff: Correct. So should the need ever present itself in the future or if the City, if additional right-of-way was secured and the road was extended we know that everything has been prepared and put in place to accommodate the potential extension of Wood Duck Lane. And connect it to Yosemite. Reeder: In the event that that property does not develop the property owner in the letter we got suggested that the City might want to put some kind of a trail access heading out to Yosemite to allow that Pioneer Hills to have access Yosemite and that in fact would be used for emergency access on this terribly long cul-de-sac. Is that something that would be feasible? Al-Jaff: We would have to study this further. Anything is possible but we know that the recommendation has always been the connection of Wood Duck Lane to Yosemite and with this proposal and at this moment we are securing the right-of-way. There is no plan at this moment to make the connection but until an actual development or request comes in we really cannot, the connection at this moment is not feasible. We don’t have the proper right-of-way. Reeder: For a road. Is that what you’re saying? Al-Jaff: Correct. Reeder: But what I asked was about a trail. Aanenson: So I’ll address that. So the park looks at this and so their recommendation was not forwarded to put a trail through there. Could they revisit it? I’m not sure unless it’s an approved surfaced for a fire truck that would also be emergency access. Typically at a minimum for emergency access you want 30 foot right-of-way with a 7 ton design so that’s something that the Chanhassen Planning Commission – May 5, 2020 17 fire department would have to look at so. Neither one of those commented that they saw this as a needed issue at this time. Reeder: Well I think it’s an issue that we make sure that property owners can develop their property if they’ve got such a large piece like that but I don’t think that addresses a trail but it seems like the reason you’re providing more right-of-way here and you’re still saying you want to connect those roads is for the safety of the people living on that very long cul-de-sac, is that correct? Al-Jaff: We are asking for the additional right-of-way to ensure that should the City extend the road, should a developer come in to develop the site that we have met ordinance requirements and secured the right-of-way through the subdivision process. Aanenson: Also it’s two fold. The temporary cul-de-sac on there was, is there a lot longer than was ever anticipated. It’s substandard in the turnaround so it’s solving that problem to get to the end of there and turn around so that’s the other issue that it’s addressing. Reeder: If, I would say it’s not solving that problem. You’re simply making a cul-de-sac a little bigger but you still have a temporary cul-de-sac there. I mean the other way would be to approach would be to not allow any more land to be developed in this area until the property owners got together and the proper right-of-way was secured to put the road through in a manner that we would normally do. Aanenson: Sure, that was suggested and I’ll let the applicant discuss that. Reeder: Mr. Chairman that’s all I have for right now. Weick: Okay thank you Commissioner Reeder. Those were good questions to raise and a good conversation. Finally Commissioner Noyes. Noyes: Yes I do have a comment question. The plan calls for a buffer on the west and north sides of the Outlot A wetland. In the future will there be any requirements of the buffer on the south side of that wetland if the connection is made using that dedicated right-of-way? I mean do we have any concerns about encroaching that wetland if at some point this connection was made? Henricksen: The wetland is delineated and the wetland delineation does extend through the right-of-way so the wetland, because this is what we call a paper street, there’s not an actual physical road there, the delineation would continue through. If a road is extended and constructed there it would have to go through the WCA process for impacts to a wetland. The buffer does stop at the right-of-way as is platted and as it should on a plat. One of the, this is kind of getting into the weeds a little I guess but on our kind of preliminary construction plan review we are going to have that wetland buffer actually extend into the right-of-way to maintain Chanhassen Planning Commission – May 5, 2020 18 a continuous buffer strip on this property. There’s a landscaping plan wherein buffers you have to install native vegetation. You know the purpose of a buffer is to kind of to buffer the wetland to create that…so that would extend into the right-of-way although it’s not technically defined as the buffer so we did take that into account looking at the preliminary plat but that’s more on the kind of construction plan review that would continue onto final plat stage. Noyes: Well there’s no, but the City doesn’t have any risks or future considerations that they need to be concerned about as it relates to that buffer should the road go through? But we have to think about different ways to approving this today? Henricksen: Not to plat no. It’s again if during the construction of the road that delineation depending on when it happens it have to re-delineated. If there are impacts to the wetland because the wetland does extend into the right-of-way. In fact the wetland goes beyond the property because it kind of looks like sort of pie shaped essentially so the wetland is a lot larger than that from what. Noyes: Okay. Henricksen: It would have to go through regulatory processes just like the wetland impact. Noyes: Okay thank you, that was very helpful. Weick: Any other questions Commissioner Noyes? Noyes: I do not, I’m good. Thank you. Weick: Okay and I will just open it up in general if someone thought of something you can certainly speak up right now. Hearing no commissioners right now we will move on to an applicant presentation. Aanenson: Yes you’re online. Did you want, who’s speaking for the applicant? Al-Jaff: Woody is speaking. Woody Love. Weick: Great thank you. Woody Love: Yes Mr. Chair and commissioners. My name is Woody Love and I represent Ann Nye at 1641 West 63rd. She has made the decision to sell her property. We looked at a 5 lot entitlement to that area but discovered that the simplest solution and to keep the character of the original Koehnen homestead this simple subdivision would accomplish it. It would be the less, least intense used land in the area and only have two residences. With that we do have a staff member from Alliant with us and my only intent would be to stand for questions so thank you. Chanhassen Planning Commission – May 5, 2020 19 Weick: Great thank you very much and appreciate you opening yourself up for questions. With that I would open it up for the commissioners and again I’ll just walk through each commissioner. If you do have a question of the applicant you may ask at this time. I will start with Commissioner Reeder. Any questions for the applicant? Reeder: I think I’m pretty good on questions right now. I may come back later if there’s something that comes up but I’m good now. Weick: Okay thank you. Commissioner Noyes? Noyes: I’m good as well, thank you. Weick: Thank you. Commissioner McGonagill? McGonagill: No questions for the applicant Mr. Chairman. Weick: Okay. Commissioner Skistad? Skistad: No questions Mr. Chairman. Weick: Thank you. And Commissioner Von Oven. Von Oven: No questions Mr. Chairman. Weick: Okay well thank you again Mr. Love for opening yourself up for questions. At this time we will open the public hearing portion of this case. Aanenson: Mr. Chair if we may, I think we’d like to read in, we’ve received some emails and then we’ll also let people know that they can call in and then there are a couple people here that also want to speak so we’ll start with just maybe summarizing the emails. Weick: Thank you. Al-Jaff: So one of the issues that we began working on this application over a year ago and one of the topics that continuously presented itself was extending Wood Duck Lane and connecting it to Yosemite. Quite a few of the individuals actually lived on Wood Duck did not want to see this connection happen for the purpose of they don’t want to see the through traffic and the intent was to keep the neighborhood as is. There were some that wanted to see the connection specifically neighbors who lived on 63rd Street and their reasoning was 63rd carried a lot of heavy traffic and they were hoping this would be their opportunity to see the traffic reduced by having a second access point up that would get individuals outside of this neighborhood other than 63rd. Since the staff report went out we did receive an email this afternoon from a resident in our community that basically wanted to point out they were in support of the development as it Chanhassen Planning Commission – May 5, 2020 20 stands and as proposed by the applicant. They also wanted to let the Planning Commission know that quite a few of the signatures on the petition to save Wood Duck Lane were from individuals that lived out of town. It’s not, they’re not community members. Those were the issues pointed out in the emails. Weick: Do we need to summarize, is that sufficient? Okay. Aanenson: As I said there were some in the packet so those are all public too so. Weick: And those are all part of the record. Aanenson: Yep so all of these will go forward to the City Council. They’ll all be part of the record correct, as will the people that want to speak. Weick: Great thank you Sharmeen. At this time I would invite anyone here in chambers that would like to comment? Oh both ways, yeah. Jay Meyer: Do you want me to come up to the mic? Weick: Yes and state your name and your address for the record please. Jay Meyer: Hi My name’s Jay Meyer. I’m on the east side of this proposed development. If you put up the map I can show you where we’re at. Reeder: Can’t hear. Jay Meyer: I’m sorry I’ll get closer. Can you hear me now? Is this good? Is this mic on? Aanenson: It’s on. It’s on… Reeder: That was better yes. Jay Meyer: Okay. I live on the east side at 1611 West 63rd. Been neighbors with Ann for 7 years or so. I just have some questions regarding this proposal and if we could put up the map that we’ve been looking at. I just want to get some things clarified but otherwise I think I’m basically okay with everything. Just want to, if you put up the one that shows the right-of-way. Weick: And while we’re pulling that up I just will say I’ll kind of note all your questions just the way this is set up and then we’ll kind of ask the appropriate people after. Jay Meyer: Okay, yeah and I want to point out that a lot of my questions have already been answered. I appreciate all the commissioners, especially Commissioner Reeder addressed many of my concerns already. So we’re on the east side so that Outlot A butts up against our property Chanhassen Planning Commission – May 5, 2020 21 and our property goes from north to 63rd south to Tacoma. Is that what that is? I didn’t know the name of that street. Anyway so if my understanding is correct this Outlot A is going to be designated as a wetlands and nothing’s going to change in it? Weick: We’ll get clarification on that yep. Jay Meyer: Okay, alright. So that’s my first question. The second question is the right-of-way that extends to the south of that wetlands would, comes up to a, you know the east edge of our property. Yeah okay. So go back to that right-of-way picture if you would. That’s fine. So that south edge of the Outlot A butts up against our’s so if, and we’re talking about a street in, which I don’t really want and I think our neighbors agree with everyone there that we don’t really want a street going through there. I’m not opposed to this path. I think what Commissioner Reeder put in I think that’s a good idea to put a trail through there to connect to Wood Duck but the question I have is, so that right-of-way in the future if either 6480 to the south or our property to the east were to develop that, we’d have to, that right-of-way would extend east right at that point? All the way to Yosemite, correct? Or that’s the question I’m asking. Weick: Yeah. Jay Meyer: Okay. So that’s my basically two questions. Does anything happen to that Outlot A once it gets designated and does that right-of-way extend straight east from there. And I guess the only other question I would have is that wetlands it’s, there’s standing water in there. Is there going to be, you know this is sub question of my first one, if there’s anything going to happen to it is there any kind of pond or lake going to be put in there or is it just going to be left alone because when it rains it drains into our property and it’s not been too big of an issue but if we could something about that I’d like to see that done so that’s all I have. Weick: Great and thank you very much for coming tonight. I really appreciate it. Kate the first question is I think about the delineation of Outlot A. Aanenson: Yeah, so it will stay an outlot but I’ll let Erik talk about where the drainage is going. I think that’s the bigger yeah, yeah. Weick: And how would it be maintained. Aanenson: Correct. So Erik if you could address that. Henricksen: Dedication of the, I’m sorry. Dedication of the outlot to the City and it being a wetland ensures that there would be no development. There would be no improvement whatsoever. The idea being we want to maintain that natural resource of a wetland so it’s an older practice to take wetlands and try to turn them into ponds. That is not consistent with our local water management plan or WCA or any other kind of regulations so the idea here being it’s a wetland. It’s covered by an outlot defined by code as something we don’t develop and the Chanhassen Planning Commission – May 5, 2020 22 intent being we would not do any improvements to that outlot so. And the City is aware of that, you know the drainage pattern of the wetland. It does, the emergency overflow essentially goes to the northeast and it kind of cuts between the properties and then flows through it’s natural drainage patter so there are no plans right now for that improvement so, and if that doesn’t answer the question just let me know. Jay Meyer: No that’s good. Weick: I think that’s good, thank you. And then the intention I guess is for that right-of-way to extend due east. Aanenson: Correct and that would only happen if somebody wanted to subdivide that lot. Weick: Correct. Aanenson: And there might have to be a delineation on that piece too if there’s wetland. I’m assuming it’s not following a straight line right there. That that would have to be delineated too. Jay Meyer: And I don’t know if that would be two wetlands. I guess it could be. Weick: But for clarification any extension beyond what was shown in the dedication, the right- of-way dedication, any extension further east would be part of a future planning case. Aanenson: That’s correct. That’s correct. Weick: Okay and would have to, we’d have to then consider wetlands and things like that that it might cross through as well. Okay. Did that and I’ll sort of go off record, script a little bit but did that answer your questions? I just want to be sure you’re covered. Jay Meyer: It did. I just want to reiterate I think this trail’s a good idea. Weick: Okay thank you. Anyone present who would like to come forward? Please do so. State your name for the record and your address. Ken Ashfeld: Thank you Mr. Chair and members of the Planning Commission. My name is Ken Ashfeld and I reside at 6480 Yosemite so I, on that larger parcel to the south that has been discussed to some extent this evening. Weick: Sure. McGonagill: Can you lean forward please, it’s hard to hear you. Chanhassen Planning Commission – May 5, 2020 23 Ken Ashfeld: I appreciate the opportunity to appear before you tonight relative to the Nye Addition. I have provided written comments to your packet and I appreciate staff getting that into your packet this evening and trying to be sensitive to your time I will try not to repeat all of that. Our property is 2.84 acres lying south of what would be the extension of Wood Duck Lane to Yosemite. My wife and I are relatively new to the community so please bear with me if my facts aren’t totally accurate but I will state them as I know them. Firstly it’s been my understanding since the development of the Pheasant Hills neighborhood that it’s been the City’s objective to extend Wood Duck Lane to Yosemite. It’s been my experience that that’s normal planning. That extraordinary long cul-de-sacs on a temporary nature are normal or common if it’s within a master plan of being extended in the future. That was 30 years ago or more and not necessarily everything has turned out that we thought would turn out that we planned 30 years ago. That further development has not occurred. When I look at the Nye Addition as it’s laid out and it’s being developed just into two parcels and actually it is the eastern parcel that would be the additional lot, I do not believe that extension of Wood Duck Lane is very viable from a number of reasons. Extending Wood Duck Lane would be pretty expensive. It’s I think 250 feet just to get to the Nye property and then it’s another 300-400 feet and that just makes the connection and then it’s about another 300 feet or so that would have to be built on my property to, in order to develop those 3 lots that were spoken of. So we‘re talking you know 1,000 feet of road that would normally provide direct access benefit to somewhere on the order of 12 lots that could share in that cost and now with the Nye Addition just coming off of the cul-de-sac I do not see the property owners there having any interest in paying for another road that doesn’t really benefit them any further. So at the end of the day unless my property absorbs all the cost of extending Wood Duck Lane plus the utilities and streets into my property it’s not going to happen in my mind. I could be wrong. I’m just taking a shot at it here. Like I said it’s pretty expensive to build. It would be my belief that if we were, if you could turn back time 30 years and you realized the difficulties of extending Wood Duck Lane at this particular point, my property would have been master planned into the Pheasant Hill development and we wouldn’t even be needing to talk about this. At the current point in time I really don’t see the ability to develop my property unless there is an alternative plan for a private drive. I made mention of that in my written comments to the Planning Commission. I don’t need to dwell into that any further unless any members of questions of myself. The one other issue that concerns me that in the absence of developing my property and putting an extension of sewer to the sewer line that was spoken of for the Nye Addition and a connection to a watermain, my existing sewer and water service line that kind of snakes through between two properties on Pintail Circle. There’s a narrow easement that was negotiated back in 1994 for that, for those sewer and water lines to my house. I don’t think those property owners really know that they’re even there and without the ability to develop and hence put in a normal water and sewer system to serve those 3 lots that we had talked about it’s going to be like that forever and at some point in time those lines will need some maintenance and digging up and it’s going to be, going to be ending up digging up those two properties to get at them. Whether that’s going to happen in my lifetime but we know it’s going to happen at some point in time and it would be, it would be ideal to have a permanent sewer and water solution for that. I believe it was intended to be temporary from the beginning but perhaps your planning staff has a better idea on that. I’m not sure about that. So that Chanhassen Planning Commission – May 5, 2020 24 concludes my remarks. You know as a vibrant city and all that you have to deal with in the city of Chanhassen these issues may seem pretty small when we’re talking just a couple few lots but this, the approval of this development as it’s shown has a profound effect on my property because for all practical purposes it’s not economically feasible to develop if the condition of development is the extension of Wood Duck Lane. So at the end of the day Wood Duck Lane remains the same and the proposal that I presented to you in my written comments, essentially it’s a private drive on a 33 foot right-of-way today serving one parcel. The only difference would be serving 4 parcels by a private drive that would be updated to city standards and my read of the PUD standards would be a 20 foot road which could reside in the 33 foot right-of- way. I think the PUD standards call for a 30 foot. It refers to just a swap of land or a corridor. So with that Mr. Chairman I would stand for any questions that you or commissioners may have. Weick: Thank you and as we go around we’ll certainly see if there are questions or clarification that anyone would need but thank you very much for coming tonight and I do promise you on behalf of all of the commissioners that there is no, there’s nothing we hear that is too, that is small. That we consider small anyway. Every issue and every case that we hear is the most important thing to somebody and we do treat them all that way. So thanks to everyone who came tonight. We also have had the phone number up for a little bit of time now. I’m not sure if anyone has called in. We do. Aanenson: No. Weick: We do not have anyone who called in, I’m sorry. So with that I will close the public hearing portion of tonight’s item. With the public hearing closed at this time I’ll let the commissioners sort of gather their thoughts here as I talk but we will go around and call on each commissioner if you do have comments or you’ve thought of something you’d like clarified, now is the time to do that. I will start with Commissioner Von Oven. Von Oven: I knew at the exact moment… Weick: You’re welcomed. That’s alright. Von Oven: Yeah so alright I’m new so I don’t know who ends up answering this or if this is just thrown out there into the ether and then maybe somebody jumps on it but I will say number one, Mr. Ashfeld’s voices the same kind of concern that I’ve had through all of this which is that 30 years ago there was a temporary solution put in place and now it feels like we’re putting another temporary solution in place so is it the position of staff that this solution is okay and that something else is to come or is Mr. Ashfeld looking for a more holistic solution that addresses his ability to do things to his property in the future. That that seems to be the case from me so I guess maybe the question is for Mr. Ashfeld and I don’t know if that’s allowed but what I got a sense of from your letter was that this was kind of sprung upon you and if there were more time that you or others or a collective may end up putting forth a solution that actually solves this 30 year temporary problem. Is that truly the case? I guess is my question. Chanhassen Planning Commission – May 5, 2020 25 Ken Ashfeld: Mr. Chair if I could answer. Weick: Sure. Ken Ashfeld: When I bought the property commissioner I was of the impression from anecdotal stories that I had heard that the City was going to push Wood Duck Lane to Yosemite and that there would be a higher density development, I think was like 5 or 6 lots that Mr. Love spoke of and that then it would be just a short cul-de-sac serving my property off of Wood Duck Lane extension to Yosemite. At that particular point assuming that there were no right-of-way issues and equitable distribution of the costs of that roadway, that all made kind of sense to me. At this particular point then I think a, and Mr. Love could probably speak to that, that a previous potential buyer ran into a roadblock of acquiring that right-of-way from property owners along Yosemite. Whether it’s myself or the Nye’s we don’t have right of eminent domain to require someone to sell us right-of-way. Only the City has that so if that property owner doesn’t wish to sell right-of-way there is really no way of acquiring it and then under the current plan there really is no benefit or motivation for the Nye property to seek an extension of Wood Duck Lane. So what I was basically saying is the, to take on that cost it is just not feasible to carry that cost on 3 lots. I would just remain on the property as it is and it would remain that way forever so unless the City decided on it’s own initiative or motivation to extend Wood Duck Lane it would never happen. Weick: Okay thank you. Aanenson: I think it’s important that we bring, maybe bring Woody Love in to speak because there is some history on that and I would concur with what he just said. There’s no motivation for the City to do a local street like that so the other thing you have, I think the other gentleman who spoke earlier also, you’d have to have all parties working together and I’ll let Mr. Love speak to that because I do believe there was another application that sought to, or another developer that sought to do that. Weick: Mr. Love if you’re still on if you could comment. Woody Love: Mr. Chair, commissioners. Yes when we, when I was contacted by Ann Nye to look at selling her property. She is really the last remnant of the Koehnen Farm. We realized it was a 5, up to 5 lots that it was entitled to but it is simply was not practical to consider the extension, much less the neighborhood reaction to that so we’ve looked at the most minimal impact way of being able to turn the land into use that can be marketed. So we viewed this as a least impacted this property first with it’s easement for drainage in the Riley-Purgatory district. This is actually kind of a glacial divide that the house is on the crest of so to the west that land was sold as an easement to the City for water quality and now the pasture to the east will be, we delineated the wetland at a great expense and realize this area has drainage issues so it’s our hope that, and I know the City’s planning if that can help address any volume or water quality control Chanhassen Planning Commission – May 5, 2020 26 issues in the future. Equally while there was, we didn’t see any incentive or possibility of dividing the land and paying for a project of that size and I think Mr. Ashfeld explained it very well. Anywhere from the raw expense the need for a private individual doesn’t have the ability to use eminent domain if it is a public question. We never had the intent of putting in the road. Right now we’re looking as a minimum impact simple subdivision and Mr. Chairman did I answer your question? Weick: Okay I’ll defer to you. Does that, are we getting clarity? Aanenson: Yes. Yeah so I guess there’s two issues here. So when the first project came through there was a lot of angst on the people on Wood Duck Lane and 63rd Street and I say a lot of angst times 100. There was a lot of it so I think they chose to take the path of least resistance and do one lot and solve the problem with the cul-de-sac. Is it solving all the problems? Is it creating future problems? But then you have to say well do they wait until 6480’s ready to go and the gentleman on 1611 are ready to go and who’s going to pay for the condemnation on the piece to the south because typically that’s development driven so otherwise everybody wait until that happened. So that’s kind of, you know we went around and round as Mr. Love stated, around and around trying to figure out the best way and this was a collective staff position on the best approach. Weick: And I’ll turn back to Commissioner Von Oven to see if you’re getting clarity on your question or not. Von Oven: I am and actually just answered my second question so thank you. Weick: Perfect. Anything else Mark? Von Oven: No. No further questions. Weick: Okay. Working up. Commissioner Skistad? Do we have you Commissioner Skistad? There you are, alright. Skistad: I’m here. I guess I don’t have any questions other than one that probably can’t be answered which is you know why wasn’t he, Mr. Ashcroft incorporated in that other development but it doesn’t apply really to this. A question for us I guess. Weick: Okay. Thank you Commissioner Skistad. Commissioner McGonagill? McGonagill: Thank you Mr. Chairman. I guess a couple clarifications to staff. And I guess we’ll come back Mr. Chairman and give our comments, is that what right now we’re going through clarification questions? Weick: And comment would be fine at this time. Chanhassen Planning Commission – May 5, 2020 27 McGonagill: Okay thank you. Kind of following up with Commissioner Reeder’s point. You could for Mr. Ashfeld’s property, right now it’s accessed off Yosemite via a private drive. That is correct staff? Al-Jaff: Yes. McGonagill: So you could also do that if you had to, if you were to come down the right-of-way off of Wood Duck Lane too. I mean there’s a couple different ways to access through there even though there’s no private today it would take some sort of a variance down the road but there’s a couple different ways to get in there down the road whenever Mr. Ashfeld would develop that. Yes it would take, require a private drive but we’ve done that before, is that correct? Al-Jaff: Yes it won’t be recommended because that means extending the length of an already very long cul-de-sac. McGonagill: Correct I understand you know and that’s the last that we want to avoid because I am all about fixing that cul-de-sac and getting the right kind of access in there and that’s not the, it’s not for sure the preferred way. However by, go ahead. Aanenson: Could I just add? I was just going to add if the property at 1611 puts a lot on that private drive and 3 on 6480 and then one on the Nye property now you’re at 5 so, and even a variance you know there’s a test for that and so, so. Al-Jaff: And you’re limited to 4 homes via private street. McGonagill: So what your point there Kate? Aanenson: You’re only allowed 4 homes via a private street so somebody’s going to get out of that opportunity unless you grant a variance and then you still haven’t solved the end of that cul- de-sac because now we’ve kind of permanently kind of notched as a non-conforming situation for the end for safety purposes so again that recommendation came from the fire department. McGonagill: It’s your point which I think is correct. That is why you’re wanting to get the easement through the future extension of Wood Duck Trail so you have the easement on Outlot A. You’re keeping all the options open so that at such time that if these people do get together and we start dividing things up even further, you’ve got future Planning Commissions have all the options in front of them to consider what they need to do. Would that be correct? Aanenson: That’s correct. McGonagill: And you know I appreciate the Nye’s effort to take the minimal lot, take the minimalized approach but we know that Chanhassen’s building out. We know that down the Chanhassen Planning Commission – May 5, 2020 28 road things are going to continue to subdivide and continue to grow and so I think we have my comment on this, we have to be very consistent and that we keep, continue to keep the options on the table for future commissions, to commissioners to take the decisions they need to take. So my position on it is, as you proposed it, as staff has proposed it with the modified but revised cul-de-sac with picking up the easement on Outlot A. Bringing it across even though Wood Duck Lane is not extended yet, you’ve given the option to as other people build down the road, other new ideas, you haven’t put yourself in a box if you understand my point Chairman. Jay Meyer: Can I just ask a clarification, is that possible? Weick: We’ve closed the public hearing. Jay Meyer: I just want to know if that private lane could come into my, if I was to subdivide would a private lane come? Aanenson: That’s what I just pointed out. There’s too many homes on it. Jay Meyer: No different one. The one original one that’s already there? From the east. Weick: Yeah I think you’ll have to do that after and I apologize unless you understood. Okay. Sorry about that Commissioner McGonagill. Did you have final comments? McGonagill: That’s it. Just my, I guess my comment would be or my position I’ll be voting in favor of staff’s recommendation. Weick: Okay thank you Commissioner McGonagill. I would move to Commissioner Noyes. Noyes: At this point I do not have any additional comments or questions, thank you. Weick: Thank you. And finally Commissioner Reeder. Reeder: Thank you Mr. Chairman. My concern is that we’re picking one development over another one to some extent. It seems like we’re saying that we’re going to amplify the original mistake of making a very long cul-de-sac which I’m sure there was a lot of discussion on at that time and they did it for some reason but now we’re adding another house on that even though I understand we are gaining a little bit larger cul-de-sac but it doesn’t seen like we’re heading toward a solution. In fact we’re maybe heading away from actually ever getting the so called temporary cul-de-sac extended as I assume staff has always been recommending. So my concern is, does it make sense to add one more house to a cul-de-sac? I’m sure it does. Does it make sense to make it maybe more difficult or not provide an avenue for the other properties in there to subdivide their property also so my thought is that I would probably be willing to vote for the proposal with the addition that we add on there some statement that indicates that it would be our, Planning Commission recommendation that consideration that future considerations for the Chanhassen Planning Commission – May 5, 2020 29 development of the other properties there would possibly include a private road to serve those properties if necessary. Weick: Okay thank you for your comments. I’m processing quite a bit right now. I do want to circle back around. After some of the commissioners that spoke earlier, I want to give you a chance if something else has come to your mind so I’ll just open it up in general. We won’t go through everybody but if somebody wanted to follow up on anything that they’ve heard now would be the opportunity to do that. Noyes: Chairman, Commissioner Noyes. Weick: Yeah. Noyes: I just think we can’t predict the future and what, who’s going to kind of go forward with the next proposal as it relates to this situation and I think while we’ve got to be cognizant of all of the options here, I don’t know that we can really try to put a solution in place that will best predict what’s going to happen in the future and I think our focus now really has to be on the proposal that’s in front of us and not and really I guess be too concerned. It’s got to be in the back of our mind but I mean it can’t be our decision can’t be solely based on what we think could happen because I don’t think we know. Weick: Thank you. I do appreciate your perspective on that. Other comments? Reeder: Mr. Chairman. Weick: Yes. Reeder: In response to that I think you can’t predict what’s going to happen but you should not prevent things from happening by dealing with one piece of property and not necessarily considering the others. Weick: Thank you. All very good points. And I do appreciate everybody putting a lot of thought into this. It is a difficult situation. We often do hear situations like this when we have to consider what might be happening around a property and are we putting ourselves in the best position to try and plan for a future contingencies and what could happen in the future. With that I would say that we could entertain a motion at this time and certainly Commissioner Reeder if you wanted it to propose a motion with some type of addition to it you are certainly free to do that as well. Reeder: Thank you Mr. Chairman I will. Weick: Okay. Chanhassen Planning Commission – May 5, 2020 30 Reeder: I move that the Chanhassen Planning Commission recommends approval of preliminary plat to subdivide 6.4 acres into two lots and one outlot as shown in plans dated March 27, 2020 subject to conditions and adopting of the Findings of Fact and Decision Recommendation. And recommend that future considerations of developing adjacent properties are given the option of a private road as an alternative to consider. McGonagill: Mr. Chairman? Weick: One moment. Hold on. Can you repeat that Kate? Aanenson: If I’m clear on that Commissioner Reeder you want to make sure there was future consideration of access to service those other properties via this same cul-de-sac? Reeder: I’m sorry could you say that again, I couldn’t quite hear you. Aanenson: Yep. So your additional recommendation is that future consideration of access to that temporary cul-de-sac to other properties be considered. That’s something the council will have to weigh in on but that’s what you wanted to add. That’s what I understood. Reeder: I didn’t hear the word private road in what you just said. What did you say? Aanenson: Access via private road. Just to be clear on that, you can’t bind a future council but for consideration and discussion we’ll put that in there as your concern. That’s what you wanted in. Reeder: Yeah I’m just, I just want to be able to raise the issue as part of a recommendation. I understand clearly that we cannot bind the council or future Planning Commissions or councils. Aanenson: Sure got it. Weick: So is this added as part of the motion or as a note? Aanenson: Well we’re not going to edit his comments. I think it was… McGonagill: Kate we can’t hear you. Aanenson: I also understood that there was a trail connection comment for consideration too so we’ll just pass those on as additional comments that the Planning Commission had if that’s okay with you Commissioner Reeder that’s as part of your motion. Reeder: No, no, I added it as part of the motion. Aanenson: Okay. Chanhassen Planning Commission – May 5, 2020 31 Weick: But is it okay to have discussion about that? Aanenson: Sure. Weick: I’m just, I’m not sure when you’re talking about a private road is that connecting to the east to Yosemite or to the west to the cul-de-sac? Reeder: As I think was said just a minute ago you could probably go either way. Weick: I’m just concerned that the stipulations on this motion are, the issue I’m having is it’s burdening, it’s burdening the existing case with unknown future development. That’s, I’m a little hung up on how the potential future development of property affects this motion specifically. McGonagill: Yeah Mr. Chairman I agree with you in that regard that the options of private drives and the way you want to develop it are always available to people to approach the Planning Commission to do the things that Commissioner Reeder’s talking about and so I do agree with you it’s an undue burden to the motion and I don’t think it’s required. We don’t know what’s going to be developed and if people want to develop with a private drive or a public drive, or public street they’ll have those avenues available to them at that point in time. You follow me Mr. Chairman? Aanenson: No I was just going to say so what I would say is there’s a motion on the floor so there can be a second or not be a second but then you can decide whether or not to forward a different motion but there is a motion on the floor so someone would have to second it to move forward. Weick: Okay. McGonagill: And Kate that motion includes the amendment to the motion? Aanenson: Correct. That’s our understanding Commissioner Reeder right? Weick: Yes. And kind of loosely worded it recommends that future considerations of developing a private road are considered. So we have a valid motion. Do we have a second? Aanenson: So that would say seeing none. Then you could ask for another motion. Weick: Yeah hearing no seconds I would entertain an amended motion or another motion. McGonagill: Mr. Chairman I’ll propose the motion as stated in the staff report. Chanhassen Planning Commission – May 5, 2020 32 Weick: If you could restate it please. McGonagill: Could you show that please? Thank you. Weick: We’ll get there. McGonagill: The Chanhassen Planning Commission recommends approval of the preliminary plat to subdivide 6.4 acres into two lots and one outlot as shown on plans dated March 27, 2020, subject to conditions and adopting of the Findings of Fact and Decision Recommendations. Weick: We have a valid motion. Do we have a second? Noyes: Chairman I will second it. Weick: Commissioner Noyes seconds the motion. Before we vote I would just comment that Commissioner Reeder your motions and your version of the motion that you amended is part of the record now. It is and Kate’s made special note to include it in the special comments that are forwarded to the City Council as well and so those comments will be prioritized in that way. Reeder: Thank you Mr. Chairman. I appreciate that. Weick: You are welcome. I’m just making some notes here. Other comments before we vote? I again thank you for your attention and detail in this matter and we will now have a roll call vote on this motion that is on the table.

Commissioner Randall recused himself from this item. Woody Love: Mr. Chairman on behalf of Ms. Nye we want to thank you the commissioners and staff for your careful consideration. Weick: Thank you and we appreciate your time this evening as well. Give me a moment to collect my thoughts here and take a couple notes. We still have some business to take care of as a Planning Commission but that was the final item in front of us this evening for voting. Again thank you to everybody really for your detail and your attention on this matter. It’s an important one. ELECTION OF CHAIR AND VICE CHAIR. Weick: The next item on the agenda this evening is new business in which we will elect a Chairman and a Vice Chairman for the upcoming session. With that I would entertain nominations. McGonagill: Mr. Chairman I’d like to nominate Steven Weick for Chairman. Weick: That’s me. McGonagill: That is you. Randall: I’d like to second the nomination. Aanenson: There you go, first and seconded it. Weick: There we have it. You guys are fast. I can’t take notes that fast. Aanenson: I got it. Chanhassen Planning Commission – May 5, 2020 35 McGonagill: All in favor say? McGonagill moved, Randall seconded to appoint Steven Weick as Chairman of the Planning Commission. All voted in favor and the motion carried unanimously with a vote of 6 to 0. Steven Weick recused himself from the vote. Weick: So we have a commissioner. It is a pleasure. I know we joke but it is a pleasure to work with all of you and I do enjoy doing it. We do need a Vice Chairman as well so we would accept nominations for Vice Chairman. McGonagill: I would like to Mr. Chairman, I’d like to nominate Mr. Randall again. Weick: We have a nomination. Skistad: I’ll second that nomination. Weick: And a second. Do we vote on this? Aanenson: Skistad yes. Weick: Yeah Skistad so I guess we would vote in the same manner. McGonagill moved, Skistad seconded to appoint Mark Randall as Vice Chairman of the Planning Commission. All voted in favor and the motion carried unanimously with a vote of 6 to 0. Mark Randall recused himself from the vote. McGonagill: Why break up a great team. Weick: Well I will speak on behalf of Commissioner Randall that he is also pleased and delighted to be Vice Chairman. Alright thank you very much matter solved. ADOPTION OF BYLAWS. Weick: We also need to adopt our bylaws. Kate. Aanenson: Yeah so they are in your packet but your bylaws. Skistad: Can’t hear you Kate. Aanenson: Oh sorry. So the bylaws were put in your packet and you adopt these annually. Nothing’s changed on anything since the last time. It’s the election of officers that are parliamentary procedure, public hearings which we successfully did tonight and so because there Chanhassen Planning Commission – May 5, 2020 36 was no changes we would certainly recommend that you approve the bylaws as you have every other year unless there’s something significant you want to change. McGonagill: I move we approve the bylaws Mr. Chairman. Weick: I will actually do a roll call vote on this one just in case someone wants to make a comment on the bylaws. Commissioner McGonagill, Randall seconded to approve adoption of the Planning Commission Bylaws. All voted in favor and the motion carried unanimously with a vote of 7 to 0. Weick: So we adopt the bylaws with the unanimous 7 to 0. APPROVAL OF MINUTES: Commissioner Skistad noted the verbatim and summary Minutes of the Planning Commission meeting dated February 18, 2020 as presented. All voted in favor and the motion carried unanimously with a vote of 7 to 0. ADMINISTRATIVE PRESENTATION. Weick: And with that we would. Aanenson: I’ll just do an update and tell you what’s coming up. A City Council update. First of all I’d like to welcome our new members for successfully making it through and for our first Zoom meeting. Thank you. It’s kind of nice to have the group back together. Our last as noted in the Minutes was February 18th so originally I thought we’d have another meeting in 2 weeks but we had a variance request but that application did not come in but we do have a meeting on September, excuse me. June 2nd and that’s an amended PUD for the Avienda project so that will be a little bit more involved. Just get everybody up to speed on where they are. They’ve just made some internal changes but we’ll go through that on September so we do not have a meeting in 2 weeks but that, sorry I keep saying September. June 2nd. June 2nd will be our next meeting and we’ll see where we’re at if we do a Zoom again or not. It’s kind of hard to do social distancing in this room with 7 people so it’s helpful to have the Chair in here and we’ll get better at this but it’s a lot of logistics of moving between people and the presentation and the like but with that I’ll just give you a quick City Council update. So while you had approved The Moments, that took quite a while to get all of it to City Council but they did approve The Moments senior housing and then Chapel Hill sign was approved in March and then we didn’t have any planning items because we haven’t had a meeting so this item will be going forward with your comments the second meeting in May for the City Council. So with that that’s all I had and gosh we made it through. Weick: We did it. Chanhassen Planning Commission – May 5, 2020 37 Aanenson: So let’s remove ourselves. Weick: Fair enough. So I will entertain a motion to adjourn. McGonagill: Before you do that Mr. Chairman I would like to just recognize staff’s work on the proposal we went through tonight. Sharmeen and the rest of them. There was a lot of effort there over not just one meeting but several in years to get to this point. Aanenson: Yes thank you for recognizing that and I’d also like to thank Erik Henricksen too who spent a lot of time and they walked the site and really spent a lot of time. Thoughtful consideration involved decisions that went into that so thank you. McGonagill: It’s just a hard one. These are always hard and these are going to come up more and more. Commissioners as we continue to build out Chan you’re going to see this occur over and over and it’s okay. That’s what we’re here to do. So thanks staff for that and appreciate that. And with that Mr. Chairman I will provide a motion to adjourn. Commissioner McGonagill moved to adjourn the meeting. All voted in favor and the motion carried unanimously with a vote of 7 to 0.
