A great place to live, work, and play Final Plat — Pioneer Pass Planning Case 06-09 September 25, 2006 Page 2 FINAL PLAT REVIEW PROPOSAL SUMMARY The applicant is requesting final plat approval for the first phase of the development consisting of 53 lots, 7 outlots and right-of-way for public streets. The proposal meets the requirements of the zoning ordinance. The following setbacks and site coverage must be met: front — 25 feet, side — 5 feet (garage), 10 feet (house) with a minimum 15 feet separation between buildings, rear — 25 feet, Bluff Creek Overlay — 40 feet; 35 percent site coverage. GRADING AND DRAINAGE The 63.4 acre site is bordered by wetlands to the north and southwest corner. The northern half of the property drains to the wetland to the north. The southern half of the property drains to the wetland in the southwest corner. A 2.8-acre area east of and adjacent to the Bluff Creek Boulevard roundabout currently drains to the west. A portion of Bluff Creek Ridge and Bluff Creek Drive will drain to the west. Staff will verify that the downstream facilities were sized to accommodate this runoff. The majority of the park area and the rear yards within Block 5 will drain to the southwest within the existing channel area; the post -development discharge rates are less than existing. Runoff from the remainder of the site will be conveyed to one of three storm water ponds within the development: one on the north side, and two on the south side, one on each side of Bluff Creek Drive. The majority of the site will be mass graded for the development. Outlot E and portions of Outlot B will not be graded. The grading along the rear lot lines in Block 2 must be adjusted so that there is positive drainage from the back of the building pads along Creek Ridge Lane. The rear -yard drainage and utility easements must be adjusted accordingly so that they encompass drainage swales that carry runoff from three or more lots. The developer must work with MnDOT to route the drainage at the low point of Bluff Creek Drive at Pioneer Trail. Before site grading commences, the existing building on the property must be razed. The developer's engineer has submitted hydrology calculations for the site and they appear to meet ordinance requirements. Storm sewer calculations and a drainage map have been submitted. Staff will review the storm sewer design to ensure it accommodates a 10-year, 24- hour storm event. An easement is required from the appropriate property owner for any off -site grading. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. Final Plat — Pioneer Pass Planning Case 06-09 September 25, 2006 Page 3 RETAINING WALLS Retaining walls are proposed at the following locations and elevations: Location Length (approximate) Maximum Height (approximate) Back of Lots 7 through 11, Block 1 and two future lots south of Lot 11, Block I 600 feet 20 feet (at Lot 8) 4-foot high tiers Future phase 95 feet 3.5 feet Back of Lots 1 and 2, Block 5 75 feet 3.5 feet Back of Lots 2 through 4, Block 5 200 feet 15 feet (at Lot 2) As a result of the proposed grade changes in the back of the lots within Block 2, the retaining wall within the future phase can be reduced in height and/or length, or possibly eliminated. Building permits are required for retaining walls four feet tall or higher and must be designed by a Structural Engineer registered in the State of Minnesota. UTILITIES Trunk sanitary sewer and watermain to serve the proposed development is currently being installed with the 2005 MUSA Expansion Improvements, City Project 04-05. Lateral sanitary sewer and watermain within the development will extend from the trunk facilities. Lateral sanitary sewer extends from the trunk within Bluff Creek Boulevard on the north (back) side of Lots 1 through 5, Block 1. This alignment was selected to minimize the sanitary sewer depth; a connection at the Bluff Creek Boulevard/Bluff Creek Ridge intersection would be excessively deep. No services will extend from this section of lateral sanitary sewer. The minimum cover over this segment of sanitary sewer shall be 7 feet; the construction plans shall be revised accordingly. Twelve -inch diameter trunk watermain will be installed within Bluff Creek Drive. The City will reimburse the developer the cost difference between an 8-inch lateral and 12-inch trunk. The City will not reimburse engineering costs for the trunk watermain oversizing. The developer will install a pressure reducing valve manhole in Bluff Creek Drive, approximately 200 feet south of Creek Vista Court. The City will reimburse the developer 100% of the cost to furnish and install this manhole. The City will not reimburse for engineering costs for the pressure reducing valve manhole. The City's Engineering Consultant, Short, Elliot and Hendrickson (SEH) performed a water service analysis for the 2005 MUSA. Based on SEH's analysis, homes with a lowest floor elevation of 935 feet or lower will likely require in -home pressure reducing valves. This will be determined based on field pressure readings. Final Plat — Pioneer Pass Planning Case 06-09 September 25, 2006 Page 4 The property was assessed $301,044.41 for the 2005 MUSA project. This assessment will be reallocated to the lots within the final plat area, as follows: $301,044.41, 81 units (preliminary plat) _ $3,716.60/unit Amount to be reassessed to lots within this final plat: $3,716.60/unit x 53 units = $ 196,979.78 Amount to be assessed to Outlot C (future development): $3,716.60/unit x 28 units = $104,064.79 The developer will be responsible for extending lateral sewer and watermain within the development; therefore, the sanitary sewer and water connection charges are waived. The property is subject to sanitary sewer and water hookup charges for all of the lots. The 2006 trunk utility hook-up charges are $1,575 per unit for sanitary sewer and $4,078 per unit for water. The 2006 SAC charge is $1,625 per unit. These fees shall be paid with the building permit; the permit applicant is responsible for payment of these fees. STREETS The site plan shows the current alignment of the north -south collector road and a roundabout per Kimley-Hour's design and report for City Project 06-05. The easterly half right-of-way of the north -south segment of the collector street will be dedicated with the Pioneer Pass development. The remaining western portion was platted with the Liberty on Bluff Creek development. Kimley-Horn completed a study on the 2005 MUSA which included street system analysis and proposed trunk utility alignments. The study identifies a north -south collector road between Pioneer Trail (CSAH 14) and the extension of Powers Boulevard (CR 17), as shown on the Pioneer Pass development plans. Bluff Creek Drive will be a 37-foot wide minor collector within an 80-foot wide right-of-way. Access spacing along this section of Bluff Creek Drive is consistent with the recommendations within the City's Comprehensive Plan. Bluff Creek Ridge, a 31-foot wide street within a 60-foot wide right-of-way will extend from Bluff Creek Boulevard at the intersection with the future phase of the Liberty on Bluff Creek development to the west. Bluff Creek Ridge will also connect to Bluff Creek Drive at the intersection at Creek Vista Court, a public cul-de-sac. Bluff Creek Ridge will ultimately be a through street within the Pioneer Pass development when the second phase is constructed. A temporary cul-de-sac is proposed at the terminus of the northern segment that will be constructed with this phase. A temporary cul-de-sac is not proposed, nor is it required at the terminus of the southern segment since only one or two lots will access the temporary street stub. Final Plat — Pioneer Pass Planning Case 06-09 September 25, 2006 Page 5 Creek Ridge Lane, a 31-foot wide street within a 60-foot wide right-of-way will extend north - south from Bluff Creek Ridge. The final plat includes Outlot A in the northeastern corner of the property. This outlot is necessary for the future road connection to the proposed Liberty at Creekside development. The developer is required to pay the Arterial Collector Roadway Fee, which is calculated as follows: 63.39 ac - 7.81 ac - 37.91 ac x $2,400/ac = $42,408.00 Gross area Right-of-way Outlots The entire area of Outlot C, future development, will be subject to this fee when it is final platted. The property was assessed $188,659.46 for the Trunk Highway 101/Lyman Boulevard/312/212 project. This assessment will be reallocated to the lots within the final plat area, as follows: $188,659.46 , 81 units (preliminary plat) _ $2,329.13/unit Amount to be reassessed to lots within this final plat: $2,329.13/unit x 53 units = $ 123,443.90 Amount to be assessed to Outlot C (future development): $2,329.13/unit x 28 units = $65,215.64 REMNANT PARCEL A remnant parcel of the parent property to Pioneer Pass was created when MnDOT acquired right-of-way to the south and east of the development. The preferred access for this parcel is from Bluff Creek Drive, since access to Pioneer Trail should be limited, and the slopes are gentler at this location. An alternative access would be from Pioneer Trail, approximately 700 feet east of Bluff Creek Drive. This access aligns with MnDOT's right-of-way strip east of future Lots 8 and 9, Block 2 of the second phase of the Pioneer Pass development. This remnant area slopes west to east; therefore, development in this area will likely require a lift station. An eight -inch lateral sanitary sewer will be installed along the east side of Lot 3, Block 4 to provide service to this area and any portion of the M[nDOT right-of-way that may be turned back in the future. Another alternative is to extend an eight -inch lateral along the north side of future Lot 8, Block 2 of the next phase of this development. The invert of this sanitary sewer will be lower than the stub described above. Final Plat - Pioneer Pass Planning Case 06-09 September 25, 2006 Page 6 The watermain within this remnant area should be looped. An eight -inch lateral shall be stubbed to the east of Bluff Creek Drive at approximately station 13+00 to provide future service to the remnant parcel and area turned back by MnDOT (if any). An eight -inch watermain stub should be installed with the next phase of Pioneer Pass in the vicinity of future Lots 8 through 12, Block 2. COMPLIANCE TABLE Description Area (sq. ft.) Fron a (ft.)

Phased Development. If the plat is a phase of a multiphased preliminary plat, the City may refuse to approve final plats of subsequent phases if the Developer has breached this Contract and the breach has not been remedied. Development of subsequent phases may not proceed until Development Contracts for such phases are approved by the City. Park charges and area charges for sewer and water referred to in this Contract are not being imposed on outlots, if any, in the plat that are designated in an approved preliminary plat for future subdivision into lots and blocks. Such charges will be calculated and imposed when the outiots are final platted into lots and blocks. 3. Preliminary Plat Status. If the plat is a phase of a multi -phased preliminary plat, the preliminary plat approval for all phases not final platted shall lapse and be void unless final platted into lots and blocks, not outiots, within two (2) years after preliminary plat approval. 4. Changes in Official Controls. For two (2) years from the date of this Contract, no amendments to the City's Comprehensive Plan, except an amendment placing the plat in the current urban service area, or official controls shall apply to or affect the use, development density, lot size, lot layout or dedications of the approved plat unless required by state or federal law or agreed to in writing by the City and the Developer. Thereafter, notwithstanding anything in this Contract to the contrary, to the full extent permitted by state law the City may require compliance with any amendments to the City's Comprehensive Plan, official controls, platting or dedication requirements enacted after the date of this Contract. 5.

Bob From: Ron A Mullenbach[mailto:ramullenbach@drhorton.com] Sent: Friday, April 07, 2006 4:33 PM To: Generous, Bob Subject: Pioneer Pass -26 Sorry about all of the last minutes dealings with Pioneer Pass. We had a business matter that came up and caused some problems and I apologize for any inconvenience you endured through that process. Hopefully we will find another piece of property in Chanhassen to work on in the future. Everyone in the office agrees that Chanhassen is a community we would certainly like to do business in. I don't know if you saw the letter the other night, which essentially transferred our application into Sever Peterson's name. However, I just want to request that staff look at staff billing through March 10' and charge D.R. Horton up to that time. If there is excess escrow, we'd like a refund. If the escrow does not cover the costs, please send me an invoice for the additional costs. I understand that you may need to have Mr. Peterson provide an escrow before you can release anything to Horton, so let me know if that is the case and I can help to coordinate. As always, please call with any questions. Thank you. Ron Mullenbach Assistant Land Development Manager D.R.

The City has a relatively high level of discretion with a variance because of the burden of proof is on the applicant to show that they meet the standards in the ordinance. PROPOSAL/SUMMARY The developer, P. A. Raften, Ins. Peterson Jacques Farm, is proposing an 81 lot single-family detached home development. Lot areas range from 11,050 to 22,666 square feet with an average lot size of 15,117 square feet. As part of the development, the developer is proposing the use of up to 12 different housing styles with building footprints ranging from 1,836 to 2,448 square feet. The property to the north is currently farmed but will shortly be submitted for development review for a proposed mixed density housing development. To the east, Town & Country Homes is proposing a 144 unit townhouse development (Planning Case #05-24 — liberty at Creekside). Pioneer Pass must provide a small segment of right-of-way to connect the projects to the north and east. To the south is the realigned Pioneer Trail and new Highway 312. To the west, Town & Country Homes is developing a 444-unit townhouse project (Planning Case 05-11 — Liberty on Bluff Creek). City water and sewer service is being provided as part of the 2005 Metropolitan Urban Services Area (MUSA) utility project currently under construction by the City. The developer will extend the trunk lines through their project to the southern and southeastern property line. The developer is providing stormwater ponding on the south and north sides of the development. The northerly pond is proposed within the Bluff Creek Overlay District due to site topography which limits were such ponding may be located. The development of this pond requires the granting of a variance to permit encroachment in to the primary zone. Access to the site will be provided by a north -south collector street (Street D) out to Pioneer Trail and by an east -west collector street from Audubon. Ultimately, the east west collector will extend to Powers Boulevard. Additionally, a future north -south collector will provide access to Lyman Boulevard. The central portion of the site has been farmed. The high point on the property is located in the west central portion of the site with an elevation of 958. The low point on the site is located in the northwest corner of the property with an elevation of 866. The Bluff Creek primary corridor is located in Outlots A and G. These Outlots may either be dedicated to the city or have a conservation easement recorded over them. The proposed development requires a comprehensive plan amendment, rezoning, subdivision, conditional use permit with variance and a wetland alteration permit. Approval of the land use amendment is subject to the Metropolitan Council approval. Staff is recommending approval of the proposed development, subject to the conditions of approval. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 3 of 22 APPLICABLE REGUATIONS Chapter 18, Subdivisions Chapter 20, Article 11, Division 2, Amendments Chapter 20, Article 11, Division 3, Variances Chapter 20, Article IV, Conditional Use Permits Chapter 20, Article VI, Wetland Protection Chapter 20, Article XIV, Division 1, Residential Low and Medium Density District Chapter 20, Article XXXI, Bluff Creek Overlay District On August 8, 2005, the Chanhassen City Council approved a Planned Unit Development concept plan for a low density residential development consisting of 120 units of twin and single-family homes. On December 8, 2003, the City approved the 2005 MUSA Alternate Urban Areawide Review (AUAR). This document was intended to review and provide mitigation measures for all development within the 2005 MUSA area. At the time of development review, each property within the 2005 MUSA area is required to reimburse the city for their propositional share, based on the land area, of the costs for completion of the AUAR. This property is responsible for $21,547.00 as their portion of the 2005 AUAR. With the update of the comprehensive plan in 1998, this property was given the two land use alternatives: Residential -Medium Density or Office/Industrial, as well as parks and open space within the Bluff Creek Corridor. The reason it was given both potential land uses was that the site has been and is farmed and was adjacent to the Benardi (Town and County) property which was similarly guided. COMPREHENSIVE PLAN AMENDMENT The developer requires a Comprehensive Plan Amendment to permit the proposed development. In calculating the City's 2020 land use designations, this 43-acre site was calculated at 50 percent industrial and 50 percent medium density residential. If this site were to be developed as all low density residential, there would 21 acres less of industrial land or a reduction from 1,269 to 1,208 or a percentage reduction of .015 percent to 8.2 percent and a 21 acre reduction in medium density land from 669 to 648 acres. The proposed amendment and rezoning assist in the furtherance of the following land use goals of the City of Chanhassen Comprehensive Plan: The plan should seek to establish sufficient land to provide a full range of housing opportunities. • The city will seek opportunities to provide transitions between different uses of different types. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 4 of 22 • Development should be phased in accordance with the ability of the city to provide services. The proposed amendment and rezoning assist in the furtherance of the following housing goals of the City of Chanhassen Comprehensive Plan: • A balanced housing supply with housing available for people of all income levels. • A variety of housing types for people in all stages of the life cycle. • Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. 2020 Land Use Plan Land Use Existing Proposed Change % of Total Commercial 212 212 0 1.4% Office/Industrial 1,229 1,208 -21 8.2% Office 117 117 0 .8% Parks & Open Space 1,466 1,466 0 9.9% Public/Semi-Public 1,242 1,242 0 8.8% Residential Large Lot 2,247 2,247 0 15.2% Residential Low Density 5,473 5,515 +42 37A% Residential Medium 669 648 -21 4.4% Density Residential High Density 398 398 0 2.6% Mixed Use 134 134 0 .9% Undevelopable 1,573 1,573 0 10.6% TOTALS 14,760 acres 14,760 acres - 100 % REZONING With approval of the land use amendment, the property is guided for Residential — Low Density Uses. The Residential — Low Density designation permits net densities of 1.2 to 4.0 units per acre. Appropriate zonings consistent with this land use designation include Residential Low and Medium Density District, RLM, Planned Unit Development — Residential (PUD-R), Single -Family Residential (RSF) and Mixed Low Density Residential (R4). The applicant is requesting to rezone approximately 43 acres from A2, Agricultural Estate District, to Residential Low and Medium Density District, RLM. The project consists of 82 single -fancily units. The proposed rezoning is consistent with the comprehensive plan amendment. The outlots adjacent to Pioneer Trail (Outlots B, C and D) and the outlots Planning Commission Planning Case No. 06-09 April 4, 2006 Page 5 of 22 containing the Bluff Creek Overlay District primary zone (Outlots A and G) will not be rezoned at this time. SUBDIVISION REVIEW LANDSCAPING/TREE PRESERVATION Total upland area (excluding wetlands, bluffs, park) 61.33 ac. Baseline canopy coverage 11.7% or 7.20 ac. Minimum canopy coverage allowed 25% or 15.33 ac. Proposed tree preservation 10.2% or 6.28 ac. Developer does not meet minimum canopy coverage allowed; therefore the difference between the baseline and proposed tree preservation is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage .92 ac. Multiplier 1.2 Total replacement 1.1 ac. or 47,916 SF Total number of trees to be planted 44 trees In addition, the applicant must increase canopy coverage to meet the minimum thirty percent required. The calculations are follows: Total reforestation area (15.33— 7.2 ac.) 8.13 ac or 354,143 SF Required canopy coverage 325trees (one tree provides 1,089 SF of canopy) The total number of trees required for the development is 369. Each lot shall have a minimum of two overstory deciduous trees planted in the front yard. Buffer yard requirements are as shown in the table: Landscaping Item Required Proposed Buffer yard B — 38 overstory trees 21 overstory trees residential lots along 76 understory trees 114 understory trees collector road 114 shrubs 0 shrubs 1900', 15' width, berm Buffer yard B — Park 9 overstory trees 14 overstory trees property 18 understory trees 10 understory trees 900', 30' width, no berm 18 shrubs 0 shrubs Buffer yard B — south 14 overstory trees 0 overstory trees property line 22 understory trees 0 understory trees 730', 20' width 36 shrubs 0 shrubs Boulevard Trees — 59 overstory trees, north 21 overstory trees, north Collector Road `D' 39 overstorytrees, south 19 overstorytrees, south Planning Commission Planning Case No. 06-09 April 4, 2006 Page 6 of 22 Landscaping Item Required Pro sed 1 per 30 feet Applicant does not meet total minimum requirements for buffer yard and boulevard tree plantings. Staff recommends that the applicant increase the planting to meet minimum ordinance requirements. According to ordinance, when a berm three feet or higher is incorporated into a buffer yard, understory and shrub plantings may be reduced by half. The berm along the collector road ranges in height from 2 feet to six feet. If the applicant can prove that berm height is a minimum of three feet or higher along the length of the road, then the buffer yard plantings can be adjusted accordingly. The applicant must also incorporate a berm and buffer yard plantings for Lot 1, Block 1 and Lot 1, Block 4. Staff recommends that the applicant include native plantings along the north Bluff Creek Overlay District primary line. This area north of the line is being impacted by grading and a restoration plan shall be developed by the applicant and approved by the city for this area. GRADING/DRAINAGE/EROSION CONTROL The 120.74 acre site is bordered by wetlands to the north and southwest corner. Before site grading commences, the existing building on the property must be razed. The property lies within the 2005 WSA Expansion study area. Kimley-Horn completed a study on the 2005 MUSA which included street system analysis and proposed trunk utility alignments. The study identifies a north -south collector road between Pioneer Trail (CSAH 14) and the extension of Powers Boulevard (CR 17). The developer's engineer submitted a site plan for Peterson Property. The plans show an approximate grading area of 46 acres (38% of the site); this includes 82 single-family house lots, public streets, two cul-de-sacs, three stormwater ponds and a public playground. Forty-nine acres (41% of the site) will be for city street and MnDOT Highway 312 construction and the remaining 25.74 acres are for outlots and future developments. A concept plan for Liberty on Bluff Creek (the property west of Peterson property) has been submitted. The developer's engineer must work with Liberty on Bluff Creek's engineer to ensure that the proposed grading on each property matches at the property line and coordinates with MnDOT for the future Highway 312 construction. The grading plan shows retaining walls in different areas. The applicant must be aware that no retaining walls are allowed within any drainage and utility easement. Building permits are required for all retaining walls and must be designed by a Structural Engineer registered in the State of Minnesota. Runoff from the northern half of the site currently drains toward the wetland on the northeastern corner and the southem half of the site drains toward the wetland on the southwestern corner. The northern portion of the site drains to proposed Pond #2 (Outlot A), which outlets to the wetland on the north property line. Runoff from the remainder of the site will be conveyed to Planning Commission Planning Case No. 06-09 April 4, 2006 Page 7 of 22 ponds within Outlots E and F, which outlet to the existing wetlands on the southwest comer of the site and eventually to Bluff Creek. The developer's engineer has submitted hydrology calculations for the site. Staff will review the calculations and forward any recommendations with the final plat report. Storm sewer calculations and a drainage map must be submitted with the final plat application. The storm sewer must be designed to accommodate a 10-year, 24-hour storm event. Additional stormwater catch basins must be added in the back yards of Lots 1-15, Block 3, along Street A in front of Lots 25-28, between Lots 15 & 16 and 4 & 5, Block 1, and the catch basin between Lots 6 & 7 must be built with two inlet openings. The last public stormwater structure that is road -accessible prior to discharging to a water body must have a 3-foot sump. The style of home and lowest floor elevation must be noted on the final grading plan. The back yard lowest entry for any house adjacent to a stormwater pond must be a minimum of three feet higher than the pond high water elevation. The final grading plan must also include a note to remove the existing driveway at Pioneer Trail. A minimum 75-foot long rock construction entrance must be shown on the plans. In addition, tree preservation fencing must be installed at the limits of tree removal. An easement is required from the appropriate property owner for any off -site grading. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. The slopes along the southwest property line of Lots 25-31, Block 2 are long and steep. This could cause drainage problems in the rear yards of the downslope properties. The applicant should demonstrate that storm water management in this area is adequate to prevent drainage issues for future homeowners. The outlet for Pond 2 appears to be designed to short-circuit the treatment capability of the pond. The outlet should be moved westward to increase the flow distance between the inlet and outlet structures. Erosion and Sediment Control Energy dissipation should be provided at the flared -end section inlet to Pond 2 within 24 hours of installation. Additional blanket should be provided for storm sewer installation area for inlet infrastructure to Pond 2. The access area should be protected with erosion control blanket upon the establishment of final grade. Erosion control blanket should be used on the slopes within Lots 31-24, Block 2. Mulch could be substituted for the blanket proposed for the berm area of Block 3 along Street D. Temporary sediment basins should be provided in existing watersheds 1 and 3 during mass grading activities. Where 10 acres or more of exposed area come to a discernable point of discharge to a wetland or waterway, a temporary basin is needed. The proposed storm water basins in proposed drainage areas 2, 6 and 7 should be temporary sediment basins until the Planning Commission Planning Case No. 06-09 April 4, 2006 Page 8 of 22 contributing areas are stabilized. The temporary outlets could be installed in place of the permanent outlets. Once the permanent outlets are installed, the basins become surfaces protected under NPDES. Perimeter control (silt fence) should be installed prior to grading along the south side of the Street D and CSAH 14 (Pioneer Trail) intersection. All silt fences near flared -end sections must be installed up and around flared -end sections so water is not discharged against the silt fence, causing it to fail. The two areas labeled as temporary sedimentation basins during the rough grading/subcut street phase of development need an outlet area defined. It is recommended to save any shredded wood material from tree removal for temporary mulch berms/vehicle exit pads as needed. Typical silt fence should be installed prior to initial rough grading activities along the west side of Outlot H to the proposed "street by others." Surface Water Management Fees Based on approximately 36.8 acres at the low density residential water quality and water quantity rates, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $165,600. Other Agencies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley -Purgatory -Bluff Creek Watershed District, Minnesota Pollution Control Agency (National Pollutant Discharge Elimination System Construction Permit), Minnesota Department of Natural Resources (dewatering permit), Army Corps of Engineers) and comply with their conditions of approval. UTILITIES Trunk sanitary sewer and watermain to serve the proposed development will be constructed with the 2005 MUSA Expansion Improvements, City Project 04-05. The developer's engineer must ensure that the proposed location of the sanitary sewer and watermain and the elevation for the sanitary sewer connection shown on the Peterson Property utility plan coincides with City Project 06-05, Bluff Creek Boulevard Improvements, utility plan. Lateral sanitary sewer and watermain within the development will extend from the trunk facilities. Staff is concerned with the proposed sanitary sewer connection to the trunk which is more than 40 feet deep along Street A at Block 1, Lots 1-5. The applicant must revise the plans and reroute the sewer to minimize the depth of the sewer main. The developer shall work with the City and the City's consultant for the Bluff Creek Boulevard improvements to reroute this sewer to an acceptable location. Also, the sewer line that runs through Stormwater Pond E needs to be moved outside the ponding limits. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 9 of 22 Watermain within Street D must be 12-inch DIP. The City will reimburse the developer the cost difference between 8-inch lateral and 12-inch trunk watermain. In -home pressure reducing water valves may be required for some lots. Utility services for the lots must be shown on the final utility plan. Installation of the private service utilities for the site will require permits and inspections through the City's Building Department. The 2005 MUSA feasibility study, which was approved by the City Council, listed an assessment to the underlying property. These assessments are for proposed trunk sanitary sewer, storm sewer, watermain, and road improvements. Since the developer will be responsible for extending lateral sewer and water service to the lots, the sanitary sewer and water connection charges will be waived. The property is subject to sanitary sewer and water hookup charges for all of the lots. The 2006 trunk utility hook-up charges are $1,575 per unit for sanitary sewer and $4,078 per unit for water. The 2006 SAC charge is $1,625 per unit. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be aware that all public utility improvements will require a preconstruction meeting before building permit issuance. Permits from the appropriate regulatory agencies will be required, including the MPCA, NPDES, Dept. of Health, Carver County, MnDOT and Watershed District. Access to Outlot B has been severed by MnDOT. Outlot B has a different zoning than the development area. The developer should work with the City to provide service stubs for the future development of the site. STREETS/ACCESS The site plan shows the current alignment of the north -south collector road and a roundabout per Kimley-Hom's design and report for City Project 06-05. The easterly half right-of-way of the north -south segment of the collector street lies within the Peterson Property development. The remaining westerly portion will be within the Liberty on Bluff Creek development. Right-of- way will be dedicated for the roadways. Public streets extending from the north -south collector include Streets A, B, C and D. Streets A, B, C and D will be a 31-foot wide back-to-back street within a 60-foot wide right-of-way. Street B ends with a 91-foot pavement radius cul-de-sac within a 120-foot radius right-of-way. Street D will intersect Pioneer Trail south of the property as part of MnDOT's Trunk Highway 312 and be 36-feet wide with an 80-foot wide right-of-way. The access for the minor collector road within the development (Street D) does not appear to line up with MnDOT's access management point at the property line. The developer will need to work with MnDOT to have the access point moved. Please contact Steve Channer with MnDOT at 651-582-1272 to move the access Planning Commission Planning Case No. 06-09 April 4, 2006 Page 10 of 22 point. Street C is 31 feet wide. The access to Pioneer Trail must be constructed in conjunction with the first phase of the development. Access to Outlot B has been severed by MnDOT. Outlot B has a different zoning than the development area. Access to Outlot B has not been determined at this time. The developer should work with MnDOT, the County and the City to determine future access to the site. The applicant must be aware that adjacent property at the northeastern corner of Peterson property has submitted a site plan (Liberty at Creekside) showing a street going through outlot (A) and intersecting with the future extension of Audubon Road. As to that, the applicant must coordinate with the adjacent property developer and need to dedicate the public street right-of- way. The developer shall dedicate street right-of-way in the northeast corner of Oulot A to provide access from the parcel to the north to the parcel to the east. An Arterial Collector Roadway Fee in the amount of $2,400/developable acre will need to be paid at the time of final plat. WETLANDS Existing Wetlands Eight wetland basins exist on -site and were delineated by Graham Environmental Services, Inc. on October 14, 2005. Wetland A is an Ag/Urban wetland (Type 2) located along the west edge of the property. The wetland is dominated by reed canary grass. Impacts to Wetland A are proposed in conjunction with the construction of the east -west collector street. Wetland B is an Ag/Urban wetland (Type 3n) located in the northeast portion of the site. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project; however, future impacts to the northeast side of this wetland may occur as part of road construction to access the Jeurissen parcel to the east. The wetland boundary along the northeast side of this wetland basin was delineated by Westwood and checked by the City in conjunction with the plans for the Jeurissen property. The boundary should be revised in accordance with that approved delineation. Wetland C is an Ag/Urban wetland (Type 3) located in the south central portion of the site, north of Pioneer Trail and within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Wetland D is an Ag/Urban wetland (Type 2) located in the south central portion of the site, west of Wetland C and within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Wetland E is an Ag/Urban wetland (Type 2) located in the eastern portion of the site within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 11 of 22 Wetland F is an Ag/Urban wetland (Type 3) located in the southwest corner of the site. The wetland contains sparse vegetation, including duckweed. Wetland G is an Ag/Urban wetland (Type 3) located in the southeast comer of the site, south of Pioneer Trail. No impact is proposed to this wetland. Wetland H is an Ag/Urban wetland (Type 2) located in the west -central portion of the site. The wetland is dominated by pinkweed and barnyard grass. Grading is proposed within this wetland to accommodate a north -south connection from Pioneer Trail to the proposed east -west collector street. Wetland Replacement A wetland replacement plan has not been submitted. The applicant should submit a complete wetland replacement plan and must receive approval of the replacement plan prior to alteration of wetlands. Wetland replacement must occur in a manner consistent with Chanhassen City Code and the Minnesota Wetland Conservation Act (MR 8420). Wetland mitigation should not be proposed for the northeast comer of the site in order to ensure adequate area for a road connection to the property to the east of the site. A wetland buffer 16.5 to 20 feet in width (with a minimum average of 16.5 feet) must be maintained around all Ag/Urban wetlands. Wetland buffer areas should be preserved, surveyed and staked in accordance with the City's wetland ordinance. The applicant must install wetland buffer edge signs, under the direction of City staff, before construction begins and must pay the City $20 per sign. All structures must be set back 40 feet from the edge of the wetland buffer. The wetland buffer setback should be shown on the plans. BLUFFS Any areas on the property that meet the City's criteria for bluffs (i.e., slope greater than or equal to 30% and a rise in slope of at least 25 feet above the toe) must be preserved. In addition, all structures must maintain a 30-foot setback from the bluff and no grading may occur within the bluff impact zone (i.e., the bluff and land located within 20 feet from the top of a bluff). The plans should be revised to show any areas meeting the City's bluff criteria. BLUFF CREEK OVERLAY DISTRICT The City of Chanhassen established the Bluff Creek Overlay District (BCOD) by ordinance in 1998 to protect the Bluff Creek Corridor, wetlands, bluffs and significant stands of mature trees through the use of careful site design and other low -impact practices. This parcel is partially encumbered by the Bluff Creek Overlay District. No alterations are allowed within the primary corridor or within the first 20 feet of the setback from the primary corridor. All structures must meet the 40-foot setback from the primary corridor. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 12 of 22 A pond (Pond 2) is currently proposed within the primary corridor. The applicant provided two alternatives for pending: one within the BCOD just north of Lots 1-6, Block 1 (Option A); and one outside of the BCOD in the proximity of proposed Lots 9-12, Block 1 (Option B). Although Option B is not within the BCOD, it is not the best option because a breach in the pond wall or an extreme storm event could cause erosion of the slope between the pond and the adjacent wetland. Additionally, due to the alignment and slopes along the northwest side of the subject property, grading will be required in the vicinity of Option A in conjunction with the construction of the east -west collector road. For these reasons, staff supports a variance for the construction of Pond 2 within the BCOD as proposed on the grading plan. PARKS AND OPEN SPACE Parks The Peterson property is located within the 2005 MUSA area at the edge of Bluff Creek and is proposed to be developed into 81 single family residential lots, 8 outlots, and right-of-way for public streets. The city's Comprehensive Park Plan calls for one acre of usable park space to be set aside for every 75 residents. The Peterson property, if developed as proposed, will result in an estimated 284 new residents (81 homes x 3.5 persons per home) moving into Chanhassen. Therefore, this subdivision generates the need for 3.79 acres of new parkland. Staff and the applicant have identified a park area (Outlot H) to be acquired as a condition of this subdivision application. Outlot H totals 205,645 square feet or 4.72 acres. With a dedication requirement of 3.79 acres, the City will be required to purchase the remaining 0.93 acres of park property. With a purchase price of $235,000 per acre, the City shall pay $218,550 to the applicant for the additional 0.93 acres. The applicant has also agreed to rough grade and cover seed the park site, and construct a 20 stall parking lot for an additional not to exceed payment of $50,000 from the City. Two access points for the parking lot are currently being studied, one off of street D and one off of the cul- de-sac on street A. Upon receipt of a warranty deed for the 4.72 acre park, and completion of the rough grading, seeding and parking lot, the city shall pay the $218,550 for the 0.93 acres of parkland in addition to an amount not to exceed $50,000 for the remaining improvements. Trails The Peterson property plat will have access to the most significant multipurpose trail corridor in the City —the Bluff Creek Trail. This trail corridor, traveling through some of the most scenic lands in Chanhassen, is currently 2/3 complete. Upon its completion, the Bluff Creek trail will travel 4 miles and feature seven pedestrian underpasses. Appropriate trail and sidewalk connectors need to be incorporated into the Peterson plat to take advantage of this valuable resource. The planning, construction, and financing of these pedestrian connectors are the responsibility of the applicant.

Average Lot Area 15,117 Setbacks: Front — 25 feet, side — 5 feet, rear — 25, Bluff Creek Primary boundary — 40 feet Maximum Site Coverage: 35 percent; Average proposed: 19 percent CONDITIONAL USE PERMIT The City of Chanhassen established the Bluff Creek Overlay District by ordinance in 1998 to protect the Bluff Creek Corridor, wetlands, bluffs and significant stands of mature trees through the use of careful site design and other low -impact practices. This parcel is partially encumbered by the Bluff Creek Overlay District. If any alterations are proposed on property within the Bluff Creek Overlay District, a conditional use permit must be obtained prior to alterations occurring. Outlots A and G contain the Bluff Creek Corridor primary zone. The Primary Corridor is designated open space. All structures must meet a 40-foot structural setback from the Primary Corridor boundary as required by Chanhassen City Code. In addition, no grading is allowed within the first 20 feet of the Primary Corridor. The plans propose grading for a stormwater pond within the Primary Corridor. This is the only feasible location for a stormwater pond due to the site topography. A variance is necessary to permit the encroachment in to the primary zone. It is reasonable to grant this variance. As a condition of approval, the applicant will be required to develop a re -vegetation for the Primary Corridor.

On March 21, 2006, the Chanhassen Planning Commission met at its regularly scheduled meeting to consider the application of D. R. Horton for a single-family residential development. The Planning Commission conducted a public hearing on the proposed development preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT The property is currently zoned Agricultural Estate District, A2. 2. The property is guided in the Land Use Plan for Residential — Medium Density and Office/Industrial 3. The legal description of the property is: The Southwest Quarter of the Northwest Quarter of Section 26, Township 116, Range 23 West; and the East half of the Northeast Quarter of Section 27, Township 116, Range 23 West, Carver County, Minnesota. 4. The Zoning Ordinance directs the Planning Commission to consider six (6) possible adverse affects of the proposed amendment. The six (6) affects and our findings regarding them are: a) The proposed action has been considered in relation to the specific policies and provisions of and has been found to be consistent with the official City Comprehensive Plan. b) The proposed use is or will be compatible with the present and future land uses of the area. c) The proposed use conforms with all performance standards contained in the Zoning Ordinance. d) The proposed use will not tend to or actually depreciate the area in which it is proposed. e) The proposed use can be accommodated with existing and planned public services and will not overburden the city's service capacity. f) Traffic generation by the proposed use is within capabilities of streets serving the property 5. SUBDIVISION FINDINGS a) The proposed subdivision is consistent with the zoning ordinance and meets all the requirements of the "RIM" Residential Low Medium Density District. 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 storm water drainage are suitable for the proposed development; d) The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; e) The proposed subdivision will not cause significant environmental damage subject to compliance with conditions of approval; f) The proposed subdivision will not conflict with easements of record, but rather will expand and provide all necessary easements. g) The proposed subdivision is not premature. A subdivision is premature if any of the following exists: 1. Lack of adequate storm water drainage. 2. Lack of adequate roads. 3. Lack of adequate sanitary sewer systems. 4. Lack of adequate off -site public improvements or support systems. 6. When approving a conditional use permit, the City must determine the capability of a proposed development with existing and proposed uses. The general issuance standards of the conditional use Section 20-232, include the following 12 items: a) The proposed development will not be detrimental to or endanger the public health, safety, comfort, convenience or general welfare of the neighborhood or the city. b) The proposed development will be consistent with the objectives of the city's comprehensive plan and this chapter. c) The proposed development will be designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area. d) The proposed development will not be hazardous or disturbing to existing or planned neighboring uses. e) The proposed development will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools; or will be served adequately by such facilities and services provided by the persons or agencies responsible for the establishment of the proposed use. f) The proposed development will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community. g) The proposed development will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare because of excessive production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash. h) The proposed development will have vehicular approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. i) The proposed development will not result in the destruction, loss or damage of solar access, natural, scenic or historic features of major significance. j) The proposed development will be aesthetically compatible with the area. k) The proposed development will not depreciate surrounding property values. 1) The proposed development will meet standards prescribed for certain uses as provided in Chapter 20, Articles IV, V and VI of the Chanhassen City Code. 7. The Board of Adjustments and Appeals shall not recommend and the City Council shall not grant a variance unless they find the following facts: a) That the literal enforcement of this chapter would cause an undue hardship. Undue hardship means that the property cannot be put to reasonable use because of its size, physical surroundings, shape or topography. Due to the topography of the site, the construction of the storm water pond in the primary zone is a reasonable request. b) The conditions upon which a petition for a variance is based are not applicable, generally, to other property within the same zoning classification. c) The purpose of the variation is not based upon a desire to increase the value or income potential of the parcel of land. d) The alleged difficulty or hardship is not a self-created hardship. e) The granting of the variance will not be detrimental to the public welfare or injurious to other land or improvements in the neighborhood in which the parcel is located. f) The proposed variation will not impair an adequate supply of light and air to adjacent property or substantially increase the congestion of the public streets or increase the danger of fire or endanger the public safety or substantially diminish or impair property values within the neighborhood. 8.

SUMMARY OF REQUEST: The developer is proposing an 82 unit single-family residential development. LEVEL OF CITY DISCRETION IN DECISION -MAKING: The City has a relatively high level of discretion in approving a Comprehensive Plan Amendment because the City is acting in its legislative or policy making capacity. The City has a relatively high level of discretion in approving rezonings because the City is acting in its legislative or policy making capacity. A rezoning must be consistent with the City's Comprehensive Plan. The City's discretion in approving or denying a preliminary plat is limited to whether or not the proposed plat meets the standards outlined in the Subdivision Regulations and Zoning Ordinance. If it meets these standards, the City must approve the preliminary plat. This is a quasi judicial decision. The City has limited discretion in approving or denying conditional use permits, based on whether or not the proposal meets the conditional use permit standards outlined in the Zoning Ordinance. If the City finds that all the applicable conditional use permit standards are met, the permit must be approved. This is a quasi judicial decision. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 2 of 22 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 variances. The City has a relatively high level of discretion with a variance because of the burden of proof is on the applicant to show that they meet the standards in the ordinance. PROPOSAL/SUMMARY The developer, D. R. Horton, Inc., is proposing an 81 lot single-family detached home development. Lot areas range from 11,050 to 22,666 square feet with an average lot size of 15,117 square feet. As part of the development, the developer is proposing the use of up to 12 different housing styles with building footprints ranging from 1,836 to 2,448 square feet. The property to the north is currently farmed but will shortly be submitted for development review for a proposed mixed density housing development. To the east, Town & Country Homes is proposing a 144 unit townhouse development (Planning Case #05-24 — Liberty at Creekside). Pioneer Pass must provide a small segment of right-of-way to connect the projects to the north and east. To the south is the realigned Pioneer Trail and new Highway 312. To the west, Town & Country Homes is developing a 444-unit townhouse project (Planning Case 05-11 — liberty on Bluff Creek). City water and sewer service is being provided as part of the 2005 Metropolitan Urban Services Area (MUSA) utility project currently under construction by the City. The developer will extend the trunk lines through their project to the southern and southeastern property line. The developer is providing stormwater ponding on the south and north sides of the development. The northerly pond is proposed within the Bluff Creek Overlay District due to site topography which limits were such ponding may be located. The development of this pond requires the granting of a variance to permit encroachment in to the primary zone. Access to the site will be provided by a north -south collector street (Street D) out to Pioneer Trail and by an east -west collector street from Audubon. Ultimately, the east west collector will extend to Powers Boulevard. Additionally, a future north -south collector will provide access to Lyman Boulevard. The central portion of the site has been farmed. The high point on the property is located in the west central portion of the site with an elevation of 958. The low point on the site is located in the northwest comer of the property with an elevation of 866. The Bluff Creek primary corridor is located in Outlots A and G. These Outlots may either be dedicated to the city or have a conservation easement recorded over them. The proposed development requires a comprehensive plan amendment, rezoning, subdivision, conditional use permit with variance and a wetland alteration permit. Approval of the land use amendment is subject to the Metropolitan Council approval. Staff is recommending approval of the proposed development, subject to the conditions of approval. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 3 of 22 APPLICABLE REGUATIONS Chapter 18, Subdivisions Chapter 20, Article II, Division 2, Amendments Chapter 20, Article 11, Division 3, Variances Chapter 20, Article IV, Conditional Use Permits Chapter 20, Article VI, Wetland Protection Chapter 20, Article XIV, Division 1, Residential Low and Medium Density District Chapter 20, Article XXXI, Bluff Creek Overlay District BACKGROUND On August 8, 2005, the Chanhassen City Council approved a Planned Unit Development concept plan for a low density residential development consisting of 120 units of twin and single-family homes. On December 8, 2003, the City approved the 2005 MUSA Alternate Urban Areawide Review (AUAR). This document was intended to review and provide mitigation measures for all development within the 2005 MUSA area. At the time of development review, each property within the 2005 MUSA area is required to reimburse the city for their propositional share, based on the land area, of the costs for completion of the AUAR. This property is responsible for $21,547.00 as their portion of the 2005 AUAR. With the update of the comprehensive plan in 1998, this property was given the two land use alternatives: Residential -Medium Density or Office/Industrial, as well as parks and open space within the Bluff Creek Corridor. The reason it was given both potential land uses was that the site has been and is farmed and was adjacent to the Benardi (Town and County) property which was similarly guided. COMPREHENSIVE PLAN AMENDMENT The developer requires a Comprehensive Plan Amendment to pen -nit the proposed development. In calculating the City's 2020 land use designations, this 43-acre site was calculated at 50 percent industrial and 50 percent medium density residential. If this site were to be developed as all low density residential, there would 21 acres less of industrial land or a reduction from 1,269 to 1,208 or a percentage reduction of .015 percent to 8.2 percent and a 21 acre reduction in medium density land from 669 to 648 acres. The proposed amendment and rezoning assist in the furtherance of the following land use goals of the City of Chanhassen Comprehensive Plan: • The plan should seek to establish sufficient land to provide a full range of housing opportunities. • The city will seek opportunities to provide transitions between different uses of different types. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 4 of 22 • Development should be phased in accordance with the ability of the city to provide services. The proposed amendment and rezoning assist in the furtherance of the following housing goals of the City of Chanhassen Comprehensive Plan: • A balanced housing supply with housing available for people of all income levels. • A variety of housing types for people in all stages of the life cycle. • Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. 2020 Land Use Plan Land Use Existing Proposed Change % of Total Commercial 212 212 0 1.4% Office/Industrial 1,229 1,208 -21 8.2% Office 117 117 0 .8% Parks & Open Space 1,466 1,466 0 9.9% Public/Semi-Public 1,242 1,242 0 8.8% Residential Large Lot 2,247 2,247 0 15.2% Residential Low Density 5,473 5,515 +42 37.4% Residential Medium 669 648 -21 4.4% Density Residential High Density 398 398 0 2.6% Mixed Use 134 134 0 .9% Undevelopable 1,573 1,573 0 10.6% TOTALS 14,760 acres 14,760 acres - 100% REZONING With approval of the land use amendment, the property is guided for Residential — Low Density Uses. The Residential — Low Density designation permits net densities of 1.2 to 4.0 units per acre. Appropriate zonings consistent with this land use designation include Residential Low and Medium Density District, RLM, Planned Unit Development — Residential (PUD-R), Single -Family Residential (RSF) and Mixed Low Density Residential (R4). The applicant is requesting to rezone approximately 43 acres from A2, Agricultural Estate District, to Residential Low and Medium Density District, RI.M. The project consists of 82 single-family units. The proposed rezoning is consistent with the comprehensive plan amendment. The outlots adjacent to Pioneer Trail (Outlots B, C and D) and the outlots Planning Commission Planning Case No. 06-09 April 4, 2006 Page 5 of 22 containing the Bluff Creek Overlay District primary zone (Outlots A and G) will not be rezoned at this time. SUBDIVISION REVIEW LANDSCAPING/TREE PRESERVATION Total upland area (excluding wetlands, bluffs, park) 61.33 ac. Baseline canopy coverage 11.7% or 7.20 ac. Minimum canopy coverage allowed 25% or 15.33 ac. Proposed tree preservation 10.2% or 6.28 ac. Developer does not meet minimum canopy coverage allowed; therefore the difference between the baseline and proposed tree preservation is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage .92 ac. Multiplier 1.2 Total replacement 1.1 ac. or 47,916 SF Total number of trees to be planted 44 trees In addition, the applicant must increase canopy coverage to meet the minimum thirty percent required. The calculations are follows: Total reforestation area (15.33— 7.2 ac.) 8.13 ac or 354,143 SF Required canopy coverage 325trees (one tree provides 1,089 SF of canopy) The total number of trees required for the development is 369. Each lot shall have a minimum of two overstory deciduous trees planted in the front yard. Buffer yard requirements are as shown in the table: Landscaping Item Required Proposed Buffer yard B — 38 overstory trees 21 overstory trees residential lots along 76 understory trees 114 understory trees collector road 114 shrubs 0 shrubs 1900', 15' width, berm Buffer yard B — Park 9 overstory trees 14 overstory trees property 18 understory trees 10 understory trees 900', 30' width, no berm 18 shrubs 0 shrubs Buffer yard B — south 14 overstory trees 0 overstory trees property line 22 understory trees 0 understory trees 730', 20' width 36 shrubs 0 shrubs Boulevard Trees — 59 overstory trees, north 21 overstory trees, north Collector Road `D' 39 overstory trees, south 19 overstory trees, south Planning Commission Planning Case No. 06-09 April 4, 2006 Page 6 of 22 Landscaping Item Required Pro sed 1 per 30 feet Applicant does not meet total minimum requirements for buffer yard and boulevard tree plantings. Staff recommends that the applicant increase the planting to meet minimum ordinance requirements. According to ordinance, when a berm three feet or higher is incorporated into a buffer yard, understory and shrub plantings may be reduced by half. The berm along the collector road ranges in height from 2 feet to six feet. If the applicant can prove that berm height is a minimum of three feet or higher along the length of the road, then the buffer yard plantings can be adjusted accordingly. The applicant must also incorporate a berm and buffer yard plantings for Lot 1, Block 1 and Lot 1, Block 4. Staff recommends that the applicant include native plantings along the north Bluff Creek Overlay District primary line. This area north of the line is being impacted by grading and a restoration plan shall be developed by the applicant and approved by the city for this area. GRADING/DRAINAGE/EROSION CONTROL The 120.74 acre site is bordered by wetlands to the north and southwest corner. Before site grading commences, the existing building on the property must be razed. The property lies within the 2005 WSA Expansion study area. Kimley-Hom completed a study on the 2005 WSA which included street system analysis and proposed trunk utility alignments. The study identifies a north -south collector road between Pioneer Trail (CSAH 14) and the extension of Powers Boulevard (CR 17). The developer's engineer submitted a site plan for Peterson Property. The plans show an approximate grading area of 46 acres (38% of the site); this includes 82 single-family house lots, public streets, two cul-de-sacs, three stormwater ponds and a public playground. Forty-nine acres (41 % of the site) will be for city street and MnDOT Highway 312 construction and the remaining 25.74 acres are for outlots and future developments. A concept plan for Liberty on Bluff Creek (the property west of Peterson property) has been submitted. The developer's engineer must work with Liberty on Bluff Creek's engineer to ensure that the proposed grading on each property matches at the property line and coordinates with MnDOT for the future Highway 312 construction. The grading plan shows retaining walls in different areas. The applicant must be aware that no retaining walls are allowed within any drainage and utility easement. Building permits are required for all retaining walls and must be designed by a Structural Engineer registered in the State of Minnesota. Runoff from the northern half of the site currently drains toward the wetland on the northeastern corner and the southern half of the site drains toward the wetland on the southwestern comer. The northern portion of the site drains to proposed Pond #2 (Outlot A), which outlets to the wetland on the north property line. Runoff from the remainder of the site will be conveyed to Planning Commission Planning Case No. 06-09 April 4, 2006 Page 7 of 22 ponds within Outlots E and F, which outlet to the existing wetlands on the southwest corner of the site and eventually to Bluff Creek. The developer's engineer has submitted hydrology calculations for the site. Staff will review the calculations and forward any recommendations with the final plat report. Storm sewer calculations and a drainage map must be submitted with the final plat application. The storm sewer must be designed to accommodate a 10-year, 24-hour storm event. Additional stormwater catch basins must be added in the back yards of Lots 1-15, Block 3, along Street A in front of Lots 25-28, between Lots 15 & 16 and 4 & 5, Block 1, and the catch basin between Lots 6 & 7 must be built with two inlet openings. The last public stormwater structure that is road -accessible prior to discharging to a water body must have a 3-foot sump. The style of home and lowest floor elevation must be noted on the final grading plan. The back yard lowest entry for any house adjacent to a stormwater pond must be a minimum of three feet higher than the pond high water elevation. The final grading plan must also include a note to remove the existing driveway at Pioneer Trail. A minimum 75-foot long rock construction entrance must be shown on the plans. In addition, tree preservation fencing must be installed at the limits of tree removal. An easement is required from the appropriate property owner for any off -site grading. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. The slopes along the southwest property line of Lots 25-31, Block 2 are long and steep. This could cause drainage problems in the rear yards of the downslope properties. The applicant should demonstrate that storm water management in this area is adequate to prevent drainage issues for future homeowners. The outlet for Pond 2 appears to be designed to short-circuit the treatment capability of the pond. The outlet should be moved westward to increase the flow distance between the inlet and outlet structures. Erosion and Sediment Control Energy dissipation should be provided at the flared -end section inlet to Pond 2 within 24 hours of installation. Additional blanket should be provided for storm sewer installation area for inlet infrastructure to Pond 2. The access area should be protected with erosion control blanket upon the establishment of final grade. Erosion control blanket should be used on the slopes within Lots 31-24, Block 2. Mulch could be substituted for the blanket proposed for the berm area of Block 3 along Street D. Temporary sediment basins should be provided in existing watersheds 1 and 3 during mass grading activities. Where 10 acres or more of exposed area come to a discernable point of discharge to a wetland or waterway, a temporary basin is needed. The proposed storm water basins in proposed drainage areas 2, 6 and 7 should be temporary sediment basins until the Planning Commission Planning Case No. 06-09 April 4, 2006 Page 8 of 22 contributing areas are stabilized. The temporary outlets could be installed in place of the permanent outlets. Once the permanent outlets are installed, the basins become surfaces protected under NPDES. Perimeter control (silt fence) should be installed prior to grading along the south side of the Street D and CSAH 14 (Pioneer Trail) intersection. All silt fences near flared -end sections must be installed up and around flared -end sections so water is not discharged against the silt fence, causing it to fail. The two areas labeled as temporary sedimentation basins during the rough grading/subcut street phase of development need an outlet area defined. It is recommended to save any shredded wood material from tree removal for temporary mulch berms/vehicle exit pads as needed. Typical silt fence should be installed prior to initial rough grading activities along the west side of Outlot H to the proposed "street by others." Surface Water Management Fees Based on approximately 36.8 acres at the low density residential water quality and water quantity rates, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $165,600. Other Agencies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley -Purgatory -Bluff Creek Watershed District, Minnesota Pollution Control Agency (National Pollutant Discharge Elimination System Construction Permit), Minnesota Department of Natural Resources (dewatering permit), Army Corps of Engineers) and comply with their conditions of approval. iTPILITIES Trunk sanitary sewer and watermain to serve the proposed development will be constructed with the 2005 WSA Expansion Improvements, City Project 04-05. The developer's engineer must ensure that the proposed location of the sanitary sewer and watermain and the elevation for the sanitary sewer connection shown on the Peterson Property utility plan coincides with City Project 06-05, Bluff Creek Boulevard Improvements, utility plan. Lateral sanitary sewer and watermain within the development will extend from the trunk facilities. Staff is concerned with the proposed sanitary sewer connection to the trunk which is more than 40 feet deep along Street A at Block 1, Lots 1-5. The applicant must revise the plans and reroute the sewer to minimize the depth of the sewer main. The developer shall work with the City and the City's consultant for the Bluff Creek Boulevard improvements to reroute this sewer to an acceptable location. Also, the sewer line that runs through Stormwater Pond E needs to be moved outside the ponding limits. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 9 of 22 Watermain within Street D must be 12-inch DIP. The City will reimburse the developer the cost difference between 8-inch lateral and 12-inch trunk watermain. In -home pressure reducing water valves may be required for some lots. Utility services for the lots must be shown on the final utility plan. Installation of the private service utilities for the site will require permits and inspections through the City's Building Department. The 2005 MUSA feasibility study, which was approved by the City Council, listed an assessment to the underlying property. These assessments are for proposed trunk sanitary sewer, storm sewer, watermain, and road improvements. Since the developer will be responsible for extending lateral sewer and water service to the lots, the sanitary sewer and water connection charges will be waived. The property is subject to sanitary sewer and water hookup charges for all of the lots. The 2006 trunk utility hook-up charges are $1,575 per unit for sanitary sewer and $4,078 per unit for water. The 2006 SAC charge is $1,625 per unit. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be aware that all public utility improvements will require a preconstruction meeting before building permit issuance. Permits from the appropriate regulatory agencies will be required, including the MPCA, NPDES, Dept. of Health, Carver County, MnDOT and Watershed District. Access to Outlot B has been severed by MnDOT. Outlot B has a different zoning than the development area. The developer should work with the City to provide service stubs for the future development of the site. STREETRACCESS The site plan shows the current alignment of the north -south collector road and a roundabout per Kimley-Hom's design and report for City Project 06-05. The easterly half right-of-way of the north -south segment of the collector street lies within the Peterson Property development. The remaining westerly portion will be within the Liberty on Bluff Creek development. Right-of- way will be dedicated for the roadways. Public streets extending from the north -south collector include Streets A, B, C and D. Streets A, B, C and D will be a 31-foot wide back-to-back street within a 60-foot wide right-of-way. Street B ends with a 91-foot pavement radius cul-de-sac within a 120-foot radius right-of-way. Street D will intersect Pioneer Trail south of the property as part of MnDOT's Trunk Highway 312 and be 36-feet wide with an 80-foot wide right-of-way. The access for the minor collector road within the development (Street D) does not appear to line up with MnDOT's access management point at the property line. The developer will need to work with MnDOT to have the access point moved. Please contact Steve Charmer with MnDOT at 651-582-1272 to move the access Planning Commission Planning Case No. 06-09 April 4, 2006 Page 10 of 22 point. Street C is 31 feet wide. The access to Pioneer Trail must be constructed in conjunction with the first phase of the development. Access to Outlot B has been severed by MnDOT. Outlot B has a different zoning than the development area. Access to Outlot B has not been determined at this time. The developer should work with MnDOT, the County and the City to determine future access to the site. The applicant must be aware that adjacent property at the northeastern corner of Peterson property has submitted a site plan (Liberty at Creekside) showing a street going through outlot (A) and intersecting with the future extension of Audubon Road. As to that, the applicant must coordinate with the adjacent property developer and need to dedicate the public street right-of- way. The developer shall dedicate street right-of-way in the northeast corner of Oulot A to provide access from the parcel to the north to the parcel to the east. An Arterial Collector Roadway Fee in the amount of $2,400/developable acre will need to be paid at the time of final plat. WETLANDS Existing Wetlands Eight wetland basins exist on -site and were delineated by Graham Environmental Services, Inc. on October 14, 2005. Wetland A is an Ag/Urban wetland (Type 2) located along the west edge of the property. The wetland is dominated by reed canary grass. Impacts to Wetland A are proposed in conjunction with the construction of the east -west collector street. Wetland B is an Ag/Urban wetland (Type 3n) located in the northeast portion of the site. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project; however, future impacts to the northeast side of this wetland may occur as part of road construction to access the Jeurissen parcel to the east. The wetland boundary along the northeast side of this wetland basin was delineated by Westwood and checked by the City in conjunction with the plans for the Jeurissen property. The boundary should be revised in accordance with that approved delineation. Wetland C is an Ag/Urban wetland (Type 3) located in the south central portion of the site, north of Pioneer Trail and within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Wetland D is an Ag/Urban wetland (Type 2) located in the south central portion of the site, west of Weiland C and within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Wetland E is an Ag/Urban wetland (Type 2) located in the eastern portion of the site within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 11 of 22 Wetland F is an Ag/Urban wetland (Type 3) located in the southwest comer of the site. The wetland contains sparse vegetation, including duckweed. Wetland G is an Ag/Urban wetland (Type 3) located in the southeast corner of the site, south of Pioneer Trail. No impact is proposed to this wetland. Wetland H is an Ag/Urban wetland (Type 2) located in the west -central portion of the site. The wetland is dominated by pinkweed and barnyard grass. Grading is proposed within this wetland to accommodate a north -south connection from Pioneer Trail to the proposed east -west collector street. Wetland Replacement A wetland replacement plan has not been submitted. The applicant should submit a complete wetland replacement plan and must receive approval of the replacement plan prior to alteration of wetlands. Wetland replacement must occur in a manner consistent with Chanhassen City Code and the Minnesota Wetland Conservation Act (MR 8420). Wetland mitigation should not be proposed for the northeast corner of the site in order to ensure adequate area for a road connection to the property to the east of the site. A wetland buffer 16.5 to 20 feet in width (with a minimum average of 16.5 feet) must be maintained around all Ag/Urban wetlands. Wetland buffer areas should be preserved, surveyed and staked in accordance with the City's wetland ordinance. The applicant must install wetland buffer edge signs, under the direction of City staff, before construction begins and must pay the City $20 per sign. All structures must be set back 40 feet from the edge of the wetland buffer. The wetland buffer setback should be shown on the plans. BLUFFS Any areas on the property that meet the City's criteria for bluffs (i.e., slope greater than or equal to 30% and a rise in slope of at least 25 feet above the toe) must be preserved. In addition, all structures must maintain a 30-foot setback from the bluff and no grading may occur within the bluff impact zone (i.e., the bluff and land located within 20 feet from the top of a bluff). The plans should be revised to show any areas meeting the City's bluff criteria. BLUFF CREEK OVERLAY DISTRICT The City of Chanhassen established the Bluff Creek Overlay District (BCOD) by ordinance in 1998 to protect the Bluff Creek Corridor, wetlands, bluffs and significant stands of mature trees through the use of careful site design and other low -impact practices. This parcel is partially encumbered by the Bluff Creek Overlay District. No alterations are allowed within the primary corridor or within the first 20 feet of the setback from the primary corridor. All structures must meet the 40-foot setback from the primary corridor. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 12 of 22 A pond (Pond 2) is currently proposed within the primary corridor. The applicant provided two alternatives for ponding: one within the BCOD just north of Lots 1-6, Block 1 (Option A); and one outside of the BCOD in the proximity of proposed Lots 9-12, Block 1 (Option B). Although Option B is not within the BCOD, it is not the best option because a breach in the pond wall or an extreme storm event could cause erosion of the slope between the pond and the adjacent wetland. Additionally, due to the alignment and slopes along the northwest side of the subject property, grading will be required in the vicinity of Option A in conjunction with the construction of the east -west collector road. For these reasons, staff supports a variance for the construction of Pond 2 within the BCOD as proposed on the grading plan. PARKS AND OPEN SPACE Parks The Peterson property is located within the 2005 MUSA area at the edge of Bluff Creek and is proposed to be developed into 81 single family residential lots, 8 outlots, and right-of-way for public streets. The city's Comprehensive Park Plan calls for one acre of usable park space to be set aside for every 75 residents. The Peterson property, if developed as proposed, will result in an estimated 284 new residents (81 homes x 3.5 persons per home) moving into Chanhassen. Therefore, this subdivision generates the need for 3.79 acres of new parkland. Staff and the applicant have identified a park area (Outlot H) to be acquired as a condition of this subdivision application. Outlot H totals 205,645 square feet or 4.72 acres. With a dedication requirement of 3.79 acres, the City will be required to purchase the remaining 0.93 acres of park property. With a purchase price of $235,000 per acre, the City shall pay $218,550 to the applicant for the additional 0.93 acres. The applicant has also agreed to rough grade and cover seed the park site, and construct a 20 stall parking lot for an additional not to exceed payment of $50,000 from the City. Two access points for the parking lot are currently being studied, one off of street D and one off of the cul- de-sac on street A. Upon receipt of a warranty deed for the 4.72 acre park, and completion of the rough grading, seeding and parking lot, the city shall pay the $218,550 for the 0.93 acres of parkland in addition to an amount not to exceed $50,000 for the remaining improvements. Trails The Peterson property plat will have access to the most significant multipurpose trail corridor in the City —the Bluff Creek Trail. This trail corridor, traveling through some of the most scenic lands in Chanhassen, is currently 2/3 complete. Upon its completion, the Bluff Creek trail will travel 4 miles and feature seven pedestrian underpasses. Appropriate trail and sidewalk connectors need to be incorporated into the Peterson plat to take advantage of this valuable resource. The planning, construction, and financing of these pedestrian connectors are the responsibility of the applicant. Planning Commission Planning Case No. 06-09 April 4, 2006 Page 13 of 22 EASEMENTS Drainage and utility easements with a minimum width of 20 feet should be provided over all existing wetlands, wetland mitigation areas, buffer areas used as public value credit and storm water infrastructure. Dedication of Outlots A and G shall be made to the city or a conservation easement shall be established over said outlots. COMPLIANCE TABLE Area ( sq. ft.) Frontage (ft.) Depth (ft.)

Average Lot Area 15,117 Setbacks: Front — 25 feet, side — 5 feet, rear — 25, Bluff Creek Primary boundary — 30 feet Maximum Site Coverage: 35 percent; Average proposed: 19 percent CONDITIONAL USE PERMIT The City of Chanhassen established the Bluff Creek Overlay District by ordinance in 1998 to protect the Bluff Creek Corridor, wetlands, bluffs and significant stands of mature trees through the use of careful site design and other low -impact practices. This parcel is partially encumbered by the Bluff Creek Overlay District. If any alterations are proposed on property within the Bluff Creek Overlay District, a conditional use permit must be obtained prior to alterations occurring. Outlots A and G contain the Bluff Creek Corridor primary zone. The Primary Corridor is designated open space. All structures must meet a 40-foot structural setback from the Primary Corridor boundary as required by Chanhassen City Code. In addition, no grading is allowed within the first 20 feet of the Primary Corridor. The plans propose grading for a stormwater pond within the Primary Corridor. This is the only feasible location for a stormwater pond due to the site topography. A variance is necessary to permit the encroachment in to the primary zone. It is reasonable to grant this variance. As a condition of approval, the applicant will be required to develop a re -vegetation for the Primary Corridor.

The City has a relatively high level of discretion with a variance because of the burden of proof is on the applicant to show that they meet the standards in the ordinance. PROPOSAL/SUMMARY The developer, D. R. Horton, Inc., is proposing an 81 lot single-family detached home development. Lot areas range from 11,050 to 22,666 square feet with an average lot size of 15,117 square feet. As part of the development, the developer is proposing the use of up to 12 different housing styles with building footprints ranging from 1,836 to 2,448 square feet. The property to the north is currently farmed but will shortly be submitted for development review for a proposed mixed density housing development. To the east, Town & Country Homes is proposing a 144 unit townhouse development (Planning Case #05-24 — Liberty at Creekside). Pioneer Pass must provide a small segment of right-of-way to connect the projects to the north and east. To the south is the realigned Pioneer Trail and new Highway 312. To the west, Town & Country Homes is developing a 444-unit townhouse project (Planning Case 05-11 — Liberty on Bluff Creek). City water and sewer service is being provided as part of the 2005 Metropolitan Urban Services Area (MUSA) utility project currently under construction by the City. The developer will extend the trunk lines through their project to the southern and southeastern property line. The developer is providing stormwater ponding on the south and north sides of the development. The northerly pond is proposed within the Bluff Creek Overlay District due to site topography which limits were such ponding may be located. The development of this pond requires the granting of a variance to permit encroachment in to the primary zone. Access to the site will be provided by a north -south collector street (Street D) out to Pioneer Trail and by an east -west collector street from Audubon. Ultimately, the east west collector will extend to Powers Boulevard. Additionally, a future north -south collector will provide access to Lyman Boulevard. The central portion of the site has been farmed. The high point on the property is located in the west central portion of the site with an elevation of 958. The low point on the site is located in the northwest comer of the property with an elevation of 866. The Bluff Creek primary corridor is located in Outlots A and G. These Outlots may either be dedicated to the city or have a conservation easement recorded over them. The proposed development requires a comprehensive plan amendment, rezoning, subdivision, conditional use permit with variance and a wetland alteration permit. Approval of the land use amendment is subject to the Metropolitan Council approval. Staff is recommending approval of the proposed development, subject to the conditions of approval. 'Planning Commission Planning Case No. 06-09 March 21, 2006 Page 3 of 22 APPLICABLE REGUATIONS Chapter 18, Subdivisions Chapter 20, Article 11, Division 2, Amendments Chapter 20, Article II, Division 3, Variances Chapter 20, Article IV, Conditional Use Permits Chapter 20, Article VI, Wetland Protection Chapter 20, Article XIV, Division 1, Residential Low and Medium Density District Chapter 20, Article XXXI, Bluff Creek Overlay District BACKGROUND On August 8, 2005, the Chanhassen City Council approved a Planned Unit Development concept plan for a low density residential development consisting of 120 units of twin and single-family homes. On December 8, 2003, the City approved the 2005 MUSA Alternate Urban Areawide Review (AUAR). This document was intended to review and provide mitigation measures for all development within the 2005 MUSA area. At the time of development review, each property within the 2005 MUSA area is required to reimburse the city for their propositional share, based on the land area, of the costs for completion of the AUAR. This property is responsible for $21,547.00 as their portion of the 2005 AUAR. With the update of the comprehensive plan in 1998, this property was given the two land use alternatives: Residential -Medium Density or Office/Industrial, as well as parks and open space within the Bluff Creek Corridor. The reason it was given both potential land uses was that the site has been and is farmed and was adjacent to the Benardi (Town and County) property which was similarly guided. _COMPREHENSIVE PLAN AMENDMENT The developer requires a Comprehensive Plan Amendment to permit the proposed development. In calculating the City's 2020 land use designations, this 43-acre site was calculated at 50 percent industrial and 50 percent medium density residential. If this site were to be developed as all low density residential, there would 21 acres less of industrial land or a reduction from 1,269 to 1,208 or a percentage reduction of .015 percent to 8.2 percent and a 21 acre reduction in medium density land from 669 to 648 acres. The proposed amendment and rezoning assist in the furtherance of the following land use goals of the City of Chanhassen Comprehensive Plan: • The plan should seek to establish sufficient land to provide a full range of housing opportunities. • The city will seek opportunities to provide transitions between different uses of different types. Planning Commission Planning Case No. 06-09 March 21, 2006 Page 4 of 22 • Development should be phased in accordance with the ability of the city to provide services. The proposed amendment and rezoning assist in the furtherance of the following housing goals of the City of Chanhassen Comprehensive Plan: • A balanced housing supply with housing available for people of all income levels. • A variety of housing types for people in all stages of the life cycle. • Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. 2020 Land Use Plan Land Use Existing Proposed Change % of Total Commercial 212 212 0 1.4% Office/Industrial 1,229 1,208 -21 8.2% Office 117 117 0 .8% Parks & Open Space 1,466 1,466 0 9.9% Public/Semi-Public 1,242 1,242 0 8.8% Residential Large Lot 2,247 2,247 0 15.2% Residential Low Density 5,473 5,515 +42 37.4% Residential Medium 669 648 -21 4.4% Density Residential High Density 398 398 0 2.6% Mixed Use 134 134 0 .9% Undevelopable 1,573 1,573 0 10.6% TOTALS 14,760 acres 14,760 acres - 100% REZONING With approval of the land use amendment, the property is guided for Residential — Low Density Uses. The Residential — Low Density designation permits net densities of 1.2 to 4.0 units per acre. Appropriate zonings consistent with this land use designation include Residential Low and Medium Density District, RIM, Planned Unit Development — Residential (PUD-R), Single -Family Residential (RSF) and Mixed Low Density Residential (R4). The applicant is requesting to rezone approximately 43 acres from A2, Agricultural Estate District, to Residential Low and Medium Density District, RLM. The project consists of 82 single-family units. The proposed rezoning is consistent with the comprehensive plan amendment. The outlots adjacent to Pioneer Trail (Outlots B, C and D) and the outlots Planning Commission Planning Case No. 06-09 March 21, 2006 Page 5 of 22 containing the Bluff Creek Overlay District primary zone (Outlots A and G) will not be rezoned at this time. SUBDIVISION REVIEW LANDSCAPINGMKEE PRESERVATION Total upland area (excluding wetlands, bluffs, park) 61.33 ac. Baseline canopy coverage 11.7% or 7.20 ac. Minimum canopy coverage allowed 25% or 15.33 ac. Proposed tree preservation 10.2% or 6.28 ac. Developer does not meet minimum canopy coverage allowed; therefore the difference between the baseline and proposed tree preservation is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage .92 ac. Multiplier 1.2 Total replacement 1.1 ac. or 47,916 SF Total number of trees to be planted 44 trees In addition, the applicant must increase canopy coverage to meet the minimum thirty percent required. The calculations are follows: Total reforestation area (15.33— 7.2 ac.) 8.13 ac or 354,143 SF Required canopy coverage 325trees (one tree provides 1,089 SF of canopy) The total number of trees required for the development is 369. Each lot shall have a minimum of two overstory deciduous trees planted in the front yard. Buffer yard requirements are as shown in the table: Landscaping Item Required Proposed Buffer yard B — 38 overstory trees 21 overstory trees residential lots along 76 understory trees 114 understory trees collector road 114 shrubs 0 shrubs 1900', 15' width, berm Buffer yard B — Park 9 overstory trees 14 overstory trees property 18 understory trees 10 understory trees 900', 30' width, no berm 18 shrubs 0 shrubs Buffer yard B — south 14 overstory trees 0 overstory trees property line 22 understory trees 0 understory trees 730', 20' width 36 shrubs 0 shrubs Boulevard Trees — 59 overstory trees, north 21 overstory trees, north Collector Road `D' 39 overstory trees, south 19 overstory trees, south Planning Commission Planning Case No. 06-09 March 21, 2006 Page 6 of 22 Landscapine Item Required Proposed 1 per 30 feet Applicant does not meet total minimum requirements for buffer yard and boulevard tree plantings. Staff recommends that the applicant increase the planting to meet minimum ordinance requirements. According to ordinance, when a berm three feet or higher is incorporated into a buffer yard, understory and shrub plantings may be reduced by half. The berm along the collector road ranges in height from 2 feet to six feet. If the applicant can prove that berm height is a minimum of three feet or higher along the length of the road, then the buffer yard plantings can be adjusted accordingly. The applicant must also incorporate a berm and buffer yard plantings for Lot 1, Block 1 and Lot 1, Block 4. Staff recommends that the applicant include native plantings along the north Bluff Creek Overlay District primary line. This area north of the line is being impacted by grading and a restoration plan shall be developed by the applicant and approved by the city for this area. GRADING/DRAINAGE/EROSION CONTROL The 120.74 acre site is bordered by wetlands to the north and southwest corner. Before site grading commences, the existing building on the property must be razed. The property lies within the 2005 MUSA Expansion study area. Kimley-Horn completed a study on the 2005 MUSA which included street system analysis and proposed trunk utility alignments. The study identifies a north -south collector road between Pioneer Trail (CSAH 14) and the extension of Powers Boulevard (CR 17). The developer's engineer submitted a site plan for Peterson Property. The plans show an approximate grading area of 46 acres (38% of the site); this includes 82 single-family house lots, public streets, two cul-de-sacs, three stormwater ponds and a public playground. Forty-nine acres (41% of the site) will be for city street and MnDOT Highway 312 construction and the remaining 25.74 acres are for outlots and future developments. A concept plan for Liberty on Bluff Creek (the property west of Peterson property) has been submitted. The developer's engineer must work with Liberty on Bluff Creek's engineer to ensure that the proposed grading on each property matches at the property line and coordinates with MnDOT for the future Highway 312 construction. The grading plan shows retaining walls in different areas. The applicant must be aware that no retaining walls are allowed within any drainage and utility easement. Building permits are required for all retaining walls and must be designed by a Structural Engineer registered in the State of Minnesota. Runoff from the northern half of the site currently drains toward the wetland on the northeastern comer and the southern half of the site drains toward the wetland on the southwestern corner. The northern portion of the site drains to proposed Pond #2 (Outlot A), which outlets to the wetland on the north property line. Runoff from the remainder of the site will be conveyed to Planning Commission Planning Case No. 06-09 March 21, 2006 Page 7 of 22 ponds within Outlots E and F, which outlet to the existing wetlands on the southwest comer of the site and eventually to Bluff Creek. The developer's engineer has submitted hydrology calculations for the site. Staff will review the calculations and forward any recommendations with the final plat report. Storm sewer calculations and a drainage map must be submitted with the final plat application. The storm sewer must be designed to accommodate a 10-year, 24-hour storm event. Additional stormwater catch basins must be added in the back yards of Lots 1-15, Block 3, along Street A in front of Lots 25-28, between Lots 15 & 16 and 4 & 5, Block 1, and the catch basin between Lots 6 & 7 must be built with two inlet openings. The last public stormwater structure that is road -accessible prior to discharging to a water body must have a 3-foot sump. The style of home and lowest floor elevation must be noted on the final grading plan. The back yard lowest entry for any house adjacent to a stormwater pond must be a minimum of three feet higher than the pond high water elevation. The final grading plan must also include a note to remove the existing driveway at Pioneer Trail. A minimum 75-foot long rock construction entrance must be shown on the plans. In addition, tree preservation fencing must be installed at the limits of tree removal. An easement is required from the appropriate property owner for any off -site grading. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. The slopes along the southwest property line of Lots 25-31, Block 2 are long and steep. This could cause drainage problems in the rear yards of the downslope properties. The applicant should demonstrate that storm water management in this area is adequate to prevent drainage issues for future homeowners. The outlet for Pond 2 appears to be designed to short-circuit the treatment capability of the pond. The outlet should be moved westward to increase the flow distance between the inlet and outlet structures. Erosion and Sediment Control Energy dissipation should be provided at the flared -end section inlet to Pond 2 within 24 hours of installation. Additional blanket should be provided for storm sewer installation area for inlet infrastructure to Pond 2. The access area should be protected with erosion control blanket upon the establishment of final grade. Erosion control blanket should be used on the slopes within Lots 31-24, Block 2. Mulch could be substituted for the blanket proposed for the berm area of Block 3 along Street D. Temporary sediment basins should be provided in existing watersheds 1 and 3 during mass grading activities. Where 10 acres or more of exposed area come to a discernable point of discharge to a wetland or waterway, a temporary basin is needed. The proposed storm water basins in proposed drainage areas 2, 6 and 7 should be temporary sediment basins until the Planning Commission Planning Case No. 06-09 March 21, 2006 Page 8 of 22 contributing areas are stabilized. The temporary outlets could be installed in place of the permanent outlets. Once the permanent outlets are installed, the basins become surfaces protected under NPDES. Perimeter control (silt fence) should be installed prior to grading along the south side of the Street D and CSAH 14 (Pioneer Trail) intersection. All silt fences near flared -end sections must be installed up and around flared -end sections so water is not discharged against the silt fence, causing it to fail. The two areas labeled as temporary sedimentation basins during the rough grading/subcut street phase of development need an outlet area defined. It is recommended to save any shredded wood material from tree removal for temporary mulch berms/vehicle exit pads as needed. Typical silt fence should be installed prior to initial rough grading activities along the west side of Outlot H to the proposed "street by others." Surface Water Management Fees Based on approximately 36.8 acres at the low density residential water quality and water quantity rates, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $165,600. Other Agencies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley -Purgatory -Bluff Creek Watershed District, Minnesota Pollution Control Agency (National Pollutant Discharge Elimination System Construction Permit), Minnesota Department of Natural Resources (dewatering permit), Army Corps of Engineers) and comply with their conditions of approval. UTILITIES Trunk sanitary sewer and watermain to serve the proposed development will be constructed with the 2005 MIJSA Expansion Improvements, City Project 04-05. The developer's engineer must ensure that the proposed location of the sanitary sewer and watermain and the elevation for the sanitary sewer connection shown on the Peterson Property utility plan coincides with City Project 06-05, Bluff Creek Boulevard Improvements, utility plan. Lateral sanitary sewer and watermain within the development will extend from the trunk facilities. Staff is concerned with the proposed sanitary sewer connection to the trunk which is more than 40 feet deep along Street A at Block 1, Lots 1-5. The applicant must revise the plans and reroute the sewer to minimize the depth of the sewer main. The developer shall work with the City and the City's consultant for the Bluff Creek Boulevard improvements to reroute this sewer to an acceptable location. Also, the sewer line that runs through Stormwater Pond E needs to be moved outside the ponding limits. Planning Commission Planning Case No. 06-09 March 21, 2006 Page 9 of 22 Watermain within Street D must be 12-inch DIP. The City will reimburse the developer the cost difference between 8-inch lateral and 12-inch trunk watermain. In -home pressure reducing water valves may be required for some lots. Utility services for the lots must be shown on the final utility plan. Installation of the private service utilities for the site will require permits and inspections through the City's Building Department. The 2005 MUSA feasibility study, which was approved by the City Council, listed an assessment to the underlying property. These assessments are for proposed trunk sanitary sewer, storm sewer, watermain, and road improvements. Since the developer will be responsible for extending lateral sewer and water service to the lots, the sanitary sewer and water connection charges will be waived. The property is subject to sanitary sewer and water hookup charges for all of the lots. The 2006 trunk utility hook-up charges are $1,575 per unit for sanitary sewer and $4,078 per unit for water. The 2006 SAC charge is $1,625 per unit. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be aware that all public utility improvements will require a preconstruction meeting before building permit issuance. Permits from the appropriate regulatory agencies will be required, including the MPCA, NPDES, Dept. of Health, Carver County, MnDOT and Watershed District. Access to Outlot B has been severed by MnDOT. Outlot B has a different Zoning than the development area. The developer should work with the City to provide service stubs for the future development of the site. The site plan shows the current alignment of the north -south collector road and a roundabout per Kinley-Horn's design and report for City Project 06-05. The easterly half right-of-way of the north -south segment of the collector street lies within the Peterson Property development. The remaining westerly portion will be within the Liberty on Bluff Creek development. Right-of- way will be dedicated for the roadways. Public streets extending from the north -south collector include Streets A, B, C and D. Streets A, B, C and D will be a 31-foot wide back-to-back street within a 60-Foot wide right-of-way. Street B ends with a 91-foot pavement radius cul-de-sac within a 120-foot radius right-of-way. Street D will intersect Pioneer Trail south of the property as part of MnDOT's Trunk Highway 312 and be 36-feet wide with an 80-foot wide right-of-way. The access for the minor collector road within the development (Street D) does not appear to line up with MnDOT's access management point at the property line. The developer will need to work with MnDOT to have the access point moved. Please contact Steve Charmer with MnDOT at 651-582-1272 to move the access Planning Commission Planning Case No. 06-09 March 21, 2006 Page 10 of 22 point. Street C is 31 feet wide. The access to Pioneer Trail must be constructed in conjunction with the first phase of the development. Access to Outlot B has been severed by MnDOT. Outlot B has a different zoning than the development area. Access to Outlot B has not been determined at this time. The developer should work with MnDOT, the County and the City to determine future access to the site. The applicant must be aware that adjacent property at the northeastern corner of Peterson property has submitted a site plan (Liberty at Creekside) showing a street going through outlot (A) and intersecting with the future extension of Audubon Road. As to that, the applicant must coordinate with the adjacent property developer and need to dedicate the public street right-of- way. The developer shall dedicate street right-of-way in the northeast comer of Oulot A to provide access from the parcel to the north to the parcel to the east. An Arterial Collector Roadway Fee in the amount of $2,400/developable acre will need to be paid at the time of final plat. WETLANDS Existing Wetlands Eight wetland basins exist on -site and were delineated by Graham Environmental Services, Inc. on October 14, 2005. Wetland A is an Ag/Urban wetland (Type 2) located along the west edge of the property. The wetland is dominated by reed canary grass. Impacts to Wetland A are proposed in conjunction with the construction of the east -west collector street. Wetland B is an Ag/Urban wetland (Type 3n) located in the northeast portion of the site. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project; however, future impacts to the northeast side of this wetland may occur as part of road construction to access the Jeurissen parcel to the east. The wetland boundary along the northeast side of this wetland basin was delineated by Westwood and checked by the City in conjunction with the plans for the Jeurissen property. The boundary should be revised in accordance with that approved delineation. Wetland C is an Ag/Urban wetland (Type 3) located in the south central portion of the site, north of Pioneer Trail and within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Wetland D is an Ag/Urban wetland (Type 2) located in the south central portion of the site, west of Wetland C and within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Wetland E is an Ag/Urban wetland (Type 2) located in the eastern portion of the site within MnDOT Right of Way. The wetland is dominated by reed canary grass. No impact is proposed to this wetland in conjunction with this project. Planning Commission Planning Case No. 06-09 March 21, 2006 Page 11 of 22 Wetland F is an Ag/Urban wetland (Type 3) located in the southwest corner of the site. The wetland contains sparse vegetation, including duckweed. Wetland G is an Ag/Urban wetland (Type 3) located in the southeast corner of the site, south of Pioneer Trail. No impact is proposed to this wetland. Wetland H is an Ag/Urban wetland (Type 2) located in the west -central portion of the site. The wetland is dominated by pinkweed and barnyard grass. Grading is proposed within this wetland to accommodate a north -south connection from Pioneer Trail to the proposed east -west collector street. Wetland Replacement A wetland replacement plan has not been submitted. The applicant should submit a complete wetland replacement plan and must receive approval of the replacement plan prior to alteration of wetlands. Wetland replacement must occur in a manner consistent with Chanhassen City Code and the Minnesota Wetland Conservation Act (MR 8420). Wetland mitigation should not be proposed for the northeast corner of the site in order to ensure adequate area for a road connection to the property to the east of the site. A wetland buffer 16.5 to 20 feet in width (with a minimum average of 16.5 feet) must be maintained around all Ag/Urban wetlands. Wetland buffer areas should be preserved, surveyed and staked in accordance with the City's wetland ordinance. The applicant must install wetland buffer edge signs, under the direction of City staff, before construction begins and must pay the City $20 per sign. All structures must be set back 40 feet from the edge of the wetland buffer. The wetland buffer setback should be shown on the plans. BLUFFS Any areas on the property that meet the City's criteria for bluffs (i.e., slope greater than or equal to 30% and a rise in slope of at least 25 feet above the toe) must be preserved. In addition, all structures must maintain a 30-foot setback from the bluff and no grading may occur within the bluff impact zone (i.e., the bluff and land located within 20 feet from the top of a bluff). The plans should be revised to show any areas meeting the City's bluff criteria. BLUFF CREEK OVERLAY DISTRICT The City of Chanhassen established the Bluff Creek Overlay District (BCOD) by ordinance in 1998 to protect the Bluff Creek Corridor, wetlands, bluffs and significant stands of mature trees through the use of careful site design and other low -impact practices. This parcel is partially encumbered by the Bluff Creek Overlay District. No alterations are allowed within the primary corridor or within the first 20 feet of the setback from the primary corridor. All structures must meet the 40-foot setback from the primary corridor. Planning Commission Planning Case No. 06-09 March 21, 2006 Page 12 of 22 A pond (Pond 2) is currently proposed within the primary corridor. The applicant provided two alternatives for ponding: one within the BCOD just north of Lots 1-6, Block 1 (Option A); and one outside of the BCOD in the proximity of proposed Lots 9-12, Block 1 (Option B). Although Option B is not within the BCOD, it is not the best option because a breach in the pond wall or an extreme storm event could cause erosion of the slope between the pond and the adjacent wetland. Additionally, due to the alignment and slopes along the northwest side of the subject property, grading will be required in the vicinity of Option A in conjunction with the construction of the east -west collector road. For these reasons, staff supports a variance for the construction of Pond 2 within the BCOD as proposed on the grading plan. PARKS AND OPEN SPACE Parks The Peterson property is located within the 2005 MUSA area at the edge of Bluff Creek and is proposed to be developed into 81 single family residential lots, 8 outlots, and right-of-way for public streets. The city's Comprehensive Park Plan calls for one acre of usable park space to be set aside for every 75 residents. The Peterson property, if developed as proposed, will result in an estimated 284 new residents (81 homes x 3.5 persons per home) moving into Chanhassen. Therefore, this subdivision generates the need for 3.79 acres of new parkland. Staff and the applicant have identified a park area (Outlot H) to be acquired as a condition of this subdivision application. Outlot H totals 205,645 square feet or 4.72 acres. With a dedication requirement of 3.79 acres, the City will be required to purchase the remaining 0.93 acres of park property. With a purchase price of $235,000 per acre, the City shall pay $218,550 to the applicant for the additional 0.93 acres. The applicant has also agreed to rough grade and cover seed the park site, and construct a 20 stall parking lot for an additional not to exceed payment of $50,000 from the City. Two access points for the parking lot are currently being studied, one off of street D and one off of the cul- de-sac on street A. Upon receipt of a warranty deed for the 4.72 acre park, and completion of the rough grading, seeding and parking lot, the city shall pay the $218,550 for the 0.93 acres of parkland in addition to an amount not to exceed $50,000 for the remaining improvements. Trails The Peterson property plat will have access to the most significant multipurpose trail corridor in the City —the Bluff Creek Trail. This trail corridor, traveling through some of the most scenic lands in Chanhassen, is currently 2/3 complete. Upon its completion, the Bluff Creek trail will travel 4 miles and feature seven pedestrian underpasses. Appropriate trail and sidewalk connectors need to be incorporated into the Peterson plat to take advantage of this valuable resource. The planning, construction, and financing of these pedestrian connectors are the responsibility of the applicant. Planning Commission Planning Case No. 06-09 March 21, 2006 Page 13 of 22 EASEMENTS Drainage and utility easements with a minimum width of 20 feet should be provided over all existing wetlands, wetland mitigation areas, buffer areas used as public value credit and storm water infrastructure. Dedication of Outlots A and G shall be made to the city or a conservation easement shall be established over said outlots. COMPLIANCE TABLE Area (sq. ft.) Frontage (ft.) Depth (ft.)

Average Lot Area 15,117 Setbacks: Front — 25 feet, side — 5 feet, rear — 25, Bluff Creek Primary boundary — 30 feet Maximum Site Coverage: 35 percent; Average proposed: 19 percent CONDITIONAL USE PERMIT The City of Chanhassen established the Bluff Creek Overlay District by ordinance in 1998 to protect the Bluff Creek Corridor, wetlands, bluffs and significant stands of mature trees through the use of careful site design and other low -impact practices. This parcel is partially encumbered by the Bluff Creek Overlay District. If any alterations are proposed on property within the Bluff Creek Overlay District, a conditional use permit must be obtained prior to alterations occurring. Outlots A and G contain the Bluff Creek Corridor primary zone. The Primary Corridor is designated open space. All structures must meet a 40-foot structural setback from the Primary Corridor boundary as required by Chanhassen City Code. In addition, no grading is allowed within the first 20 feet of the Primary Corridor. The plans propose grading for a stormwater pond within the Primary Corridor. This is the only feasible location for a stormwater pond due to the site topography. A variance is necessary to permit the encroachment in to the primary zone. It is reasonable to grant this variance. As a condition of approval, the applicant will be required to develop a re -vegetation for the Primary Corridor.

R. Horton — Planning Case No. 06-09 Pioneer Pass Request for a comprehensive plan Land Use Amendment from Residential — Medium Density and Office/Industrial to Residential - Low Density (approximately 43 acres); Rezoning from Agricultural Estate District, A2, to Residential Low and Medium Density District, RLM (approximately 43 acres); Preliminary Plat creating 82 lots, 8 outlots and right-of-way for public streets (approximately 73 acres); Conditional Use Permit for development within the bluff creek overlay district with a Variance for encroachment into the primary zone; and a Wetland Alteration Permit for the grading and filling of wetlands on property located north of Pioneer Trail (1600 Pioneer Trail) at future Highway 312. On March 21, 2006, the Chanhassen Planning Commission met at its regularly scheduled meeting to consider the application of D. R. Horton for a single-family residential development. The Planning Commission conducted a public hearing on the proposed development preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT The property is currently zoned Agricultural Estate District, A2. 2. The property is guided in the Land Use Plan for Residential — Medium Density and Office/Industrial 3. The legal description of the property is: The Southwest Quarter of the Northwest Quarter of Section 26, Township 116, Range 23 West; and the East half of the Northeast Quarter of Section 27, Township 116, Range 23 West, Carver County, Minnesota. 4. The Zoning Ordinance directs the Planning Commission to consider six (6) possible adverse affects of the proposed amendment. The six (6) affects and our findings regarding them are: a) The proposed action has been considered in relation to the specific policies and provisions of and has been found to be consistent with the official City Comprehensive Plan. b) The proposed use is or will be compatible with the present and future land uses of the area. c) The proposed use conforms with all performance standards contained in the Zoning Ordinance. SCANNED d) The proposed use will not tend to or actually depreciate the area in which it is proposed. e) The proposed use can be accommodated with existing and planned public services and will not overburden the city's service capacity. f) Traffic generation by the proposed use is within capabilities of streets serving the property. 5. SUBDMSION FINDINGS a) The proposed subdivision is consistent with the zoning ordinance and meets all the requirements of the "RIM' Residential Low Medium Density District. 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 storm water drainage are suitable for the proposed development; d) The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; e) The proposed subdivision will not cause significant environmental damage subject to compliance with conditions of approval; f) The proposed subdivision will not conflict with easements of record, but rather will expand and provide all necessary easements. g) The proposed subdivision is not premature. A subdivision is premature if any of the following exists: 1. Lack of adequate storm water drainage. 2. Lack of adequate roads. 3. Lack of adequate sanitary sewer systems. 4. Lack of adequate off -site public improvements or support systems. 6. When approving a conditional use permit, the City must determine the capability of a proposed development with existing and proposed uses. The general issuance standards of the conditional use Section 20-232, include the following 12 items: a) The proposed development will not be detrimental to or endanger the public health, safety, comfort, convenience or general welfare of the neighborhood or the city. b) The proposed development will be consistent with the objectives of the city's comprehensive plan and this chapter. c) The proposed development will be designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area. d) The proposed development will not be hazardous or disturbing to existing or planned neighboring uses. e) The proposed development will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools; or will be served adequately by such facilities and services provided by the persons or agencies responsible for the establishment of the proposed use. f) The proposed development will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community. g) The proposed development will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare because of excessive production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash. h) The proposed development will have vehicular approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. i) The proposed development will not result in the destruction, loss or damage of solar access, natural, scenic or historic features of major significance. j) The proposed development will be aesthetically compatible with the area. k) The proposed development will not depreciate surrounding property values. 1) The proposed development will meet standards prescribed for certain uses as provided in Chapter 20, Articles IV, V and VI of the Chanhassen City Code. The Board of Adjustments and Appeals shall not recommend and the City Council shall not grant a variance unless they find the following facts: a) That the literal enforcement of this chapter would cause an undue hardship. Undue hardship means that the property cannot be put to reasonable use because of its size, physical surroundings, shape or topography. Due to the topography of the site, the construction of the storm water pond in the primary zone is a reasonable request. b) The conditions upon which a petition for a variance is based are not applicable, generally, to other property within the same zoning classification. c) The purpose of the variation is not based upon a desire to increase the value or income potential of the parcel of land. 0 d) The alleged difficulty or hardship is not a self-created hardship. e) The granting of the variance will not be detrimental to the public welfare or injurious to other land or improvements in the neighborhood in which the parcel is located. f) The proposed variation will not impair an adequate supply of light and air to adjacent property or substantially increase the congestion of the public streets or increase the danger of fire or endanger the public safety or substantially diminish or impair property values within the neighborhood. 8. The planning report #06-09 dated March 21, 2006, prepared by Robert Generous, et al, is incorporated herein. RECOMMENDATION The Planning Commission recommends that the City Council approve the proposed development including a comprehensive plan Land Use Amendment from Residential — Medium Density and Office/Industrial to Residential - Low Density (approximately 43 acres); Rezoning from Agricultural Estate District, A2, to Residential Low and Medium Density District, RLM (approximately 43 acres); Preliminary Plat creating 81 lots, 9 outlots and right-of-way for public streets (approximately 73 acres); Conditional Use Permit for development within the bluff creek overlay district with a Variance for encroachment into the primary zone; and a Wetland Alteration Permit for the grading and filling of wetlands ADOPTED by the Chanhassen Planning Commission this 21s` day of March, 2006.

PIONNER PASS,1600 PIONEER TRAIL, APPLICANT SEVER PETERSON: REQUEST FOR A COMPREHENSIVE PLAN LAND USE AMENDMENT FROM RESIDENTIAL -MEDIUM DENSITY AND OFFICE/INDUSTRIAL TO RESIDENTIAL - LOW DENSITY (APPROXIMATELY 43 ACRES): REZONING FROM AGRICULTURAL ESTATE DISTRICT (A2) TO RESIDENTIAL LOW AND MEDIUM APPROIXMATELY 73 ACRES); CONDITIONAL USE PERMIT FOR DEVELOPMENT WITHIN THE BLUFF CREEK OVERLAY DISTRICT WITH A VARIANCE FOR ENCROACHMENT INTO THE PRIMARY ZONE; AND WETLAND Public Present: Name Address Joel Cooper John Chadwick Paul Bilotta JRH Inc. J. Edwin Chadwick LLC HMI Development Kate Aanenson: Thank you Mayor, members of the council. This project before you tonight, Pioneer Pass is located also in the 2005 MUSA area. It will gain it's access off the new frontage road, then also off of Pioneer Trail. This request involves a couple of actions, most specifically land use amendment from residential medium density or office industrial to low density. Of approximately 43 acres. It also includes the rezoning to RLM and we'll spend a little bit of time going through that zoning district itself. Also preliminary plat and a conditional use for the work m City Council Meeting — April 24, 2006 within the Bluff Creek Overlay District and a variance for the pond in the overlay district. And then also a wetland alteration permit for grading and filling. Most importantly I'd like to talk a little bit about the land use on this. If you want to turn to page 4 of the staff report, we put a table in there showing you where we are to date on the different land uses. Based on the previous discussion, it may be hard to believe this but our largest land use is low density, large lots or single family is our largest land use. If you go to the housing goals, we've always said it will predominantly 80% single family detached, so what you're seeing now is the introduction of some other product types. The RLM zoning district, which you look at this ... was anticipated in some of the properties within the overlay district. As we looked at the overlay district, as we talked about in the past, there were two ways to accomplish providing the entire creek corridor, and I'll go back to my old map here. The goal was to provide a corridor that runs from the north side to the south along the Bluff Creek and instead of acquiring it all, which we could have done, we've worked through the zoning technique to provide that corridor because we have had experiences where people plotting up the lot, so in this specific piece came before you and asked for concept PUD to discuss whether or not you wanted to look at the medium density or the industrial. At that time the applicants, also in talking with staff, we wanted to provide different housing styles on the property so this would be a single family product. So what we did on page 4 is we put the compliance table to date on that percentage of units, and it was discussed actually even on the bottom of page 2, talking about the 43 acres. Again, try to keep this simplistic but when we did our compliance on the land use, or our calculations, we assumed that a 50/50 split. If it went industrial or residential, we assumed based on the land use calculations for housing densities at 50/50 split. So in looking at the units lost among the medium densities were, that would have showed up on that 50% also. Again we used those numbers to keep track of that. We had to make certain assumptions for assessments and we looked at those numbers of, number of units, also for utilities. Water rate structure. Storm water fees so we look at all those numbers. So looking at the overall, we're taking into low density. Adding 42 acres, or taking out of the medium density 21. So that ties back to that percentage. Again in looking at the zoning that could have been applied on this, they could have gone with the medium or the industrial but at the concept this council gave direction conceptually, while it doesn't have legal standing, in good faith they moved forward using the low density. I'll talk about the specific questions on the green, I'm not going to talk too much about that except that we did talk that it slopes down towards the creek, and the park is located in that area that actually provides a good transition between Liberty at Bluff Creek and this project itself. And also as the Park Director mentioned, we believe it's in a good site as far as the visibility from a major collector road, which would be another nice view as you come down the collector road. Turn at the round about and then ... minor collector that they'll be putting in place. So access on this, another issue under zoning itself, because there is other industrial zoning on this piece of property, so what the developer, but then also MnDot has and if they decide to turn back that right-of-way, excess right-of-way, that would stay under guiding the industrial, which would tie into the triangular piece that we talked about earlier. Everybody tracking me on that? So we, so this property is in excess MnDot right-of-way. This property here. Mayor Furlong: We expect it will be? Kate Aanenson: Yeah, it could be turned back at some time when they're done with the project. 39 As A33 City Council Meeting — April 24, 2006 Mayor Furlong: Okay. Kate Aanenson: But we're not changing the guiding on that. We're only changing the guiding, so this will still remain industrial, and that ties back into... going to go here, and then this is also, what we talked about earlier, is the industrial piece on the other side of the creek. Mayor Furlong: If it remains industrial or will it be dual guided? Kate Aanenson: Probably still be dual guided. But we would recommend probably a transition area of some professional office, kind of in that area. Buffering. But the issue there then too was access. Again, as I indicated, it will have access off of the collector road. They are also building a minor collector on this portion. So they're... the issue that we have is there's a gap there between the MnDot right-of-way and getting to Pioneer. So on this map doesn't show it but the subdivision map does show that connection onto Pioneer, so there's two access points in and out of that subdivision also. And as the City Engineer indicated earlier, that access point was, this access point was actually over here earlier. Approximately in this area. It's not been moved over to this point as part of the design build. Councilman Lundquist: So they're building the road. Kate Aanenson: To tie in... Councilman Lundquist: From their development all the way to, is that Bluff Creek Drive coming up there or what is that? Kate Aanenson: Yes. This is the new aligned Bluff Creek Drive, right. Councilman Peterson: They're not building right up to that though? Kate Aanenson: Yes they are. Building right across. Yes, we are making that a condition of approval because there's a gap and we wanted two access points in the subdivision. Councilman Peterson: And that part is in MnDot's right now? Kate Aanenson: It is. It's a condition of approval that they secure that to make that access happen. Yeah, so we're not putting all the pressure back on this road, so the two access points. So I mentioned again these are all public streets. This one being the 80 foot. The rest of them would all be the 60 foot. There's a compliance table in the staff report talking about the lot sizes. Again this is the RLM zoning district. We did apply this when we updated the city code to give another zoning option within the RLM zone. This is the area that's being preserved. There is buildable area up in the, let me go to the plat itself. There is some buildable area on this side of the creek, and on the north side. They are providing an additional access through their property to the Creekside, Liberty at Creekside development. So again this is an opportunity for them to take advantage of some of the impervious surface. In working with the grades, and our road construction through the project itself, the best place to locate that pond without putting a big 40 City Council Meeting — April 24, 2006 retaining wall outside of the overlay district is where it is, and that's why the staff supported the variance on the location of that pond. Part of it is our construction of the road. I talked about. Mayor Furlong: Is that ... second? Secondary. Kate Aanenson: Yes. It's actually in the primary, so that's the first time we've done that but in looking at where, if we pulled it up closer to those lots, we didn't want that proximity... so the staff supported that again with some significant grading that you're not seeing... so that's already being impacted by grading of the road, so we felt that was, it's already been impacted by our road design, so putting the pond there didn't add additional impact. Councilman Lundquist: How much of the primary zone is it? Kate Aanenson: So this is, it's hard to see on this. This is the grading, the lines. Can you zoom in a pinch more, just up in this comer right here. These lines are pretty light but the significant impact in grading right through here on that, and I know it's hard to see. For the mad. So that's where this pond follows, so the back's up in here is pretty much the primary line right there. Councilman Lundquist: Go back to the, okay. Kate Aanenson: Right in here. Councilman Lundquist: Okay. So essentially the whole pond is in the primary zone? Kate Aanenson: Correct. Correct. And again, the reason we did support that early on is that we already were impacting that with our, so since it was, the grades were being changed for our project, it made sense to put it there. Instead of putting it closer to the backs of the lots where engineering had some concern. The... change of grades right in the back of the retaining walls. Councilman Lundquist: Kate, what's in that green spot in the back there? No, in the opposite corner. Kate Aanenson: Here? Councilman Lundquist: Yeah. Kate Aanenson: That's a wetland associated with the creek. Councilman Lundquist: Okay, and so. Kate Aanenson: And this is all. Councilman Lundquist: There you go. That one you just touched, right there. So putting a pond right there, is that still in the primary zone? Kate Aanenson: Correct. 41 City Council Meeting — April 24, 2006 Councilman Lundquist: Okay, so it doesn't matter, alright. Kate Aanenson: But again that's part of the green space that they're capitalizing on, which I'll segway to now and then I'll swing back to parks. In the compliance table we give you all the lots. Lots average 15,000 square feet. The smallest being 9. It does say that 5 and a 10. The plat you're looking had some, it shows 10 all the way around on all sides. It does allow, 10 foot. In talking with the applicant. Mayor Furlong: Are you talking about side yard setback? Kate Aanenson: Correct. But with a 70 foot, but. Mayor Furlong: So then... Kate Aanenson: Right, but what I'd like to recommend is that we had 5 in here, that is allowed as a minimum. That we change that to a 5 and a 10. That would be 15 feet inbetween, to allow that flexibility because this was designed for specific buildings. We had custom product homes. Right now they're trying to introduce a number of different builders in here, and this zoning district also allows 35% impervious, again anticipating that we want to do a single family that would be able to capitalize on the overall district, using that green space. This does allow for the 35% hard cover within the subdivision itself. So if you went with a bigger home on these smaller lots, it would fit based on the impervious calculation, and that's again in the RLM zone. So they're showing the 10 on either side. And that was with the 70 foot wide home in there. Some of them are coming in a little bit larger so, they certainly can do the 5. 5 and 10, so you'd rotate that. So we have at least 15 feet between, there's probably some that certainly would be the 10 and 10. So you'd have the, which is our standard. Councilman Lundquist: So you're asking for 5 and 10 or 10 and 10? Kate Aanenson: 5 and 10. I'd like to leave that flexibility in because you may have a larger home, if you get those, there's some builders that they're talking to that we've worked with that do a little bit larger home than the 70. We'd like that flexibility to be able to introduce that. But I would say there'll probably be a lot of them at the 10 and 10. Councilman Lundquist: So they're asking for 10 and 10 or? Kate Aanenson: They're asking for 5 and 5. Councilman Lundquist: Oh okay. Kate Aanenson: I'm recommending that we go to 5 and 10. Councilman Lundquist: Okay, I'm with you. Ex City Council Meeting — April 24, 2006 Kate Aanenson: That's what the code allows, 5 and 5 and I asked them if they would be willing to go to the 5 and 10. On the bottom of page 15, again the average lot size on that is the 15,000. That's also in the compliance table on one of the sheets on your site plan too. So it does have some lots obviously that are over on the cul-de-sac lots, and again this project itself will have some very interesting views which is certainly of interest to Mr. Peterson who owns the property to take, to really capitalize on the serentic area here, and then also as a part of the extraction that was negotiated through the park commission and park director, provide an opportunity obviously for these residents... for the Bluff Creek and that would be a public park. I think that's all I had unless there was some specific questions on anything. I'd be happy to answer any questions that you have. Mayor Furlong: Any questions for staff? Councilman Peterson: Kate what have we got, what do we have for similar setback between single family homes...? What did we do at Settlers West? Kate Aanenson: They're 10 and 10, but they're all maxed out. That's a 25% impervious and all those houses are going either at 24 or right at 25 when they come in, so in looking at this, I think the uniqueness again, allowing the impervious to go higher because we've created that green space in the back, it allows people to come back and do those porches, decks, those sort of things without the fact that they're going over, and that's really key to what we believe is giving that flexibility on developments, as opposed to putting those much larger homes on the minimum 15,000 which everybody tries to maximize the number of lots, so we believe that the flexibility's built in here and using this different zoning technique. Again we anticipated this application somewhere in the district. The 2005. Mayor Furlong: I guess the question is, should we reserve time on future agendas for hard surface coverage...? Kate Aanenson: Oh you may. You may. Mayor Furlong: And I guess ... I guess that's a question in terms of initial design and wherever you put the setbacks and what's allowed so. For a builder to build out ... what they're allowed to do so if that's where. Kate Aanenson: Right, and I'll go back to the discussion we've had this with the Planning Commission too. Our zoning ordinance was built at a time when our standard lot frontage, 90 foot and then you've got 10 on each side, left you a 70 foot home. Most of the larger home builders now are doing a 74 or 75, 76 foot wide home. They can't meet the setbacks, and not only that, they're much deeper. So you know we tried to look at how do we balance that and that's why we introduce this zoning district too. Now certainly going a small 80 foot frontage wouldn't work on that but it allows you to go the 35%. They can do the bigger lots, but they'd also have to create that green space, so it's an opportunity where you've got the right area. Mayor Furlong: And that 35%, that would be valid for what, the 12,000 foot lots... 43 City Council Meeting — April 24, 2006 Kate Aanenson: That's correct. Over the entire site. Correct. Mayor Furlong: Any questions at this point? Just one question I had, this was in the conditions with regards to the parks. With regard to the economics of the additional park. Mr. Gerhardt, any comments on that or? Todd Gerhardt: I think the language that is written in the report reflect the purchase agreement with D.R. Horton. I think for everything to be equal, I like the Mayor's point that we talked about earlier that as long as it doesn't go any higher, but if it goes lower, then we'd want to adjust the dollar amount so. Mayor Furlong: I asked the question of where the dollar amount came up and I understood that it was from the previous purchase agreement, and if that's where... Todd Gerhardt: That was a good recommendation Mayor. Mayor Furlong: ... the only question I had, is that still a valid concern on our part. Todd Gerhardt: I think we'll address that with the final plat. I would think they're probably continuing to market the property and might have a purchase agreement by then and we can even get a dollar amount in there. Mayor Furlong: Okay. Kate Aanenson: Yeah, I think obviously getting some preliminary plat approval allows them to accelerate their marketing, correct. Mayor Furlong: Alright. Any other questions for staff at this point? Councilman Peterson: Kate from a historical, the only concern I've got to some degree is we're doing a zoning change without having any sense of a look or feel of what they're planning to put down there. And I don't remember if we've ever done that. Kate Aanenson: Well, except that we do it on a standard subdivision all the time. We don't ask if, when Pinehurst came in, we didn't look at their product. We've asked them to whoever they're working with. It's happened sometimes that they'll reassemble lot lines that you can do administratively. If they have to drop one lot to make some builder happy, they split part of a lot and join it to the other two. If you follow me, so that may happen, but certainly that's what they need that information to go forward with marketing. And we do have this size lots, actually Springfield was the last PUD that we did which is off of Lyman, and that's an average of 15,000. Some as small as 11. The problem is the 30% and still that's sometimes in a PUD the single family, you really need to get closer to the 35 for the smaller lot. And that's how we looked at. Councilman Peterson: The subdivision... rezoning. Kate Aanenson: Well PUD would. Yeah, a PUD would. 44 City Council Meeting — April 24, 2006 Councilman Peterson: But then we gain control with PUD... Kate Aanenson: Correct. Correct. Well you still, our ordinance says we don't do design standards or design review on a single family home, so. We only do it on multi family, or attached. Mayor Furlong: Any other questions at this point? You have some more questions... At this point in time —the applicant, good evening. If they would like to address the council, you're more than welcome. John Chadwick: Good evening. My name is John Chadwick. I live at 11430 Zion Circle, Bloomington, Minnesota. Representing the Peterson family. Thank you Mr. Mayor, council, staff. Chance to be here. It seems like I've had a chance to visit with most of your staff throughout this last year and a half, and it's been a good experience. Not that there hasn't been a little back and forth, but I think that's really good. And what we tried to do, I think it's about a 63 acre site when you look at it corner to comer to comer to meander and wherever she all goes, but it does, it is part of the Bluff Creek and I think there's 18-19 acres of that that's being preserved. And then there's a 4 acre park, 4.79 acre, 4.73 acre park, the yellow area right there that should be of great benefit to the people here. It's available as Kate said, you've got a nice drive what you're looking at when you're coming from the north and south. You come in from the southem collector road, that comes in off of Pioneer, you can get there. You can see it, everybody can get to it and can use it. That should be a great amenity. We did a road connection and everything as a public street. We tried our best to follow the AUAR as far as we need to build a southern collector, so we did that. We want to tie into the east/west, north/south collector. We did that. We got that nice round about that gives us a beautiful sight lines to the development, and you know I didn't design all this stuff. We got design consultants and engineer is here making that whole thing work out. And we've got about 80 foot drop from the top of the farm all the way down to the water level of Bluff Creek, and so it's a pretty nice deal for making single family. It would be really difficult to do big, flat buildings on that thing without grading the heck of her. So we, the street's curved, turned out to the roads and the way they lay out there. I'm sure there's going to be a lot of grading but there's been a lot of farming done there too, so we don't have to run into too many trees on this particular site. And as far as down on the Bluff Creek area, some of that hasn't been farmed. Of course that will be restored as part of this development and put it back into a more of a natural state. Sony about that Sever. The deal's probably done. And so with that we've got 81 lots and we're anxious to get going on that and we are actively marketing that and we've got a lot of great inquiries on that and unsolicited inquiries now that the word is out. It's out there and people like to be in Chanhassen. And we like to make that possible and with your help and support we're going to make that possible. And make it as part of this area, this whole AUAR area that we worked so hard on. We're here to answer any questions. We don't need to belabor the point. The hour is late. And then... other areas that we'd like to get on to so with that I will stop and I thank you all for your hard work. Mayor Furlong: Very good. Thank you Mr. Chadwick. Any questions? Very good. Any follow up questions? 45 City Council Meeting — April 24, 2006 Councilman Lundquist: Just had one quick one Mr. Mayor. Kate, the south side of the property, as that will be some sort of, oh yeah. Of commercial, industrial, office. Whatever that might be there. On the topography, landscaping, whatever that might be, do we have what we feel would be adequate buffering between the backs of those houses? As Mr. Undestad can attest to, we just went through a fun one like that as we transition from a single family neighborhood to what was an open space is now an industrial office. Kate Aanenson: Yeah, it's a good question. I didn't touch too much on this but they're actually buffering through landscaping the collector because you've got street on both sides like on these lots. And then also on this minor collector, there is no direct access. You have to get that via this street, so that would be a nice experience as you come along the park there. Also providing additional landscaping here. To this area too, we've also talked about letting through their covenants, letting those homeowners know that this is excess right-of-way and may be developed as something else in the future. But there is a pretty good change in grade but we've talked about some things that we can come back with on final plans too. How we take care of addressing that and then the transition of buffer. Councilman Lundquist: Is the grade change down or up? Kate Aanenson: Right now it's berm. But it could go away and that's kind of what, they've addressed that so that's why we need to put in the covenants that may go away and it may be something else, and that's kind of what we're talking about. Leaving that in place but figuring out, because if a different use came in and we'd want to provide some other type, whether it's fencing or. It may be an office with a greater setback that may work too and get access via this road and how we orientate that and stuff so, that's something that we'd work on too between now and final plat. Councilman Lundquist: Okay. Just you know a concern. We bring in office industrial or commercial, they're not generally amenable to giving you a bigger setback. They're trying to put as big a box on there as they possible can so. Maybe it's something we want to look at between now and final as well to make sure that we've got some protection so that 8-10 years down the road when that end of that gets... Mayor Furlong: So will that remain zoned A2 guided... Kate Aanenson: That's correct. Yep, it will remain zoned A2 and guided for office or, excuse me, office industrial/medium density. Mayor Furlong: Or medium density. Kate Aanenson: And that's one we could look at too as we update the comp plan, if you wanted to get something more specific, that could be one that we'll target too. To look. Mayor Furlong: Other questions at this point? Thoughts and comments. m City Council Meeting — April 24, 2006 Councilman Lundquist: Want me to go first this time Craig? Councilman Peterson: Sure. I can't play the protagonist all night. Councilman Lundquist: Mr. Mayor, my thoughts. I'm glad to see a different style in here. On this property. It seems a lot of the issues that we just went through on the last one we won't face here. Kate, thanks for the comparison on the Springfield. That helps me get a little bit better handle because when I look at the numbers and I think about 12 or 13,000 acre, or square foot lot you know with a 35% hard cover on there, that seems like you know, you could share dinner with your neighbors through the kitchen window if you tried hard, so that's good there. The, you know obviously the proximity to the park and all of that is good. I'm a little bit leery I guess not having a builder necessarily identified that you know, I want to make sure we get a good quality piece and I feel like as we, we're at the point now where if we approve this, you know yes there's a final plat to go yet and hopefully we'll have that not so minor detail taken care of at that point, but you know I want to make sure that we lay out all the guidelines and we don't get somebody comes in and builds some lower quality pieces on there and there's not a heck of a lot we can do about it at that point so. Either that's a concern that's out there, but this being in the preliminary phase, if we get to the final I'd be a lot more concerned about it at that point but overall pretty straight forward. I like the way it's laid out. It again still, it's a lot of units in there when you look at it on paper. It'll be sandwiched probably inbetween two townhouse developments which, and a future office industrial and a major highway and some collector streets and all kinds of good stuff so it will be interesting to see how the marketing process goes. Wish you luck there. Hopefully we can get a good builder in there, but as it stands overall I'm comfortable with what we've got at the stage that we're at now. You know look for some of that buffering on the south side, and the final and hopefully we can get to a point where we've got a builder identified so we can get a little bit more comfortable with the products that we'd be looking for so, those are my comments. Mayor Furlong: Good, thank you. Other thoughts. Councilwoman Tjornhom: Well I feel comfortable with the project. I think that you know, I don't really have a fear that we're going to have some disaster strike and we'll have horrible round houses or something in these developments. I think that we'll come up with property owners and some builders that have good design standards and are going to you know, the neighborhood will only sell if they have good houses in them so I'm trusting that that, I'll follow my wisdom on that. I think that it's a good neighborhood because it will have a different variety of price points perhaps than some of the other neighborhoods we've had. We won't have maybe million dollar homes. We'll have more something in reach for other people in the community. I'm guessing. Maybe not. Maybe higher... I think that neighborhood flows nicely. I think the park is a good asset. And I leaned over to Councilman Lundquist while you were up presenting your plans and I said it looks like a good door knocking neighborhood. I like that. Homes close together and easy access. Other than that I guess I don't have any problems with it and I look forward to seeing how it develops. Mayor Furlong: Councilman Peterson. 47 City Council Meeting — April 24, 2006 Councilman Peterson: I would echo my two peers and previous comments so nothing to add. Councilman Lundquist: One quick mulligan though. It is the one concern I do have that I'll just reiterate again is the loss of the industrial piece. You know we talked about it at concept. We talked about it as we go along that you know, I guess we can't let it slide by. Probably still beating a dead horse but I'll continue to do that as we. Mayor Furlong: I'll pick up on that and give you some of my thoughts. Perhaps something that we or staff want to look at with the excess right-of-way piece to maybe take away the dual on that. I'm not advocating that but consider it. Looking at if it works. Maybe then giving it a single guiding, which, because that was a point Councilman Lundquist raised at the time that we approved concept plan. We've learned more from that ... and where things might be going but that might be something to look at. Not advocating it but maybe that's the opportunity. You know overall I'm pleased with what I've heard this evening. It helped me gain some comfort. I think my concern is when we're dealing with smaller lot sizes, and here some of these are pretty good sized lots. It's probably more of a function of the topography and the lots going down to the creek, you know. Because there are some small ones here too. I'm just a little concerned with some of the setbacks in here. I think a normal single family residential we're at 30 and 30 on the front and back. 30 in the front. Kate Aanenson: Yeah, we've actually approved a lot of, yeah. If you go to like Longacres, a lot of those were given the 20 on the front. On this PUD's. Same with Springfield. Where we try to preserve trees. Actually I think we did that on a few on Pinehurst too where if you recall as you go to that ravine, so we try to stay at a minimum of 25. That gives you better stacking on the front driveway. You'll see that on another project that's coming forward that we stick with at least a 25. Mayor Furlong: Because this is, you know setbacks are something I've mentioned before... especially with 5 on a side yard, or even what's being proposed here as the 5 and 10. 15 feet is not a lot between two homes and you know my, on the impervious surface, you know 35% on a 22,000 acre lot, that's quite a bit that can be used. Would it all be used? Perhaps not but it could be used. My preference is to try to keep that down just from a storm water management, especially near the creek. And maybe I can give... and try to force that to 30. Keep that at 35 and those side yard setbacks... but I would be interested in some thoughts there. A lot of the flexibility is important but at the same time it's that look and feel that's going to add 5 more feet to the lawn distance perhaps between homes but again... Yeah, 15 feet is not much. Kate Aanenson: Can I throw this out Mayor since they're working on, at this point if we look at the 5 and 10 when they come back for final plat, when they've got a builder, then you'll have a better idea. Kind of what their needs are because if we eliminate it now, then we've prevented them from doing anything bigger than that 70, so maybe it's a percentage, if they kind of know who their builders are. Mayor Furlong: And I guess the assumption there is it might be a single builder. Maybe there... but is there something that prevents us from relaxing those setbacks? I've got to believe that we can't be more restrictive... Is there some reason that we couldn't relax those. m City Council Meeting — April 24, 2006 Kate Aanenson: That's what I'm saying. Keep it open so you can make it more restrictive, well I guess that wouldn't work that way. Mayor Furlong: Well if we wanted, and I don't even know if anybody else agrees with me. Councilman Peterson: Yeah, I'm tracking with you. I understand. Kate Aanenson: Yeah, well just qualify it. Say at final plat we review based on the builders that it may be changed. Mayor Furlong: What I heard tonight and your comment with Settlers West was another most recent example is that, whatever those setbacks are, they go to a maximum. ...but so, from our standpoint I guess... Kate Aanenson: Yeah, I guess in this instance too the ordinance does say 5 and 5, so we've asked them in good faith if they would consider accepting the 5 and the 10, which they said they'd like to do. So, or are willing to do, but I think you know looking at who the builder is, we have a better understanding, or the builders if there's a couple of them, kind of what their needs are. So maybe it's even greater like a 7 and 10, I'm not sure. Just give me that 2 extra feet. Because sometimes it affects when people do side, side loaded, side decks. Those sort of things. Mayor Furlong: Right, I understand and I'd be interested in other members of council comments but to relax something based on specific requirements... Whatever it is, it's going to be that or more requested so... I've gained a lot of comfort this evening with the presentations than I was coming in tonight so. When we talked about the concept plan, we talked about some single families... single family. The lot sizes and those setbacks are something that concerned me a lot and ... trying to visualize that. If we're going to give in the impervious surface, I guess I'd prefer to keep sides at 10 and 10, but open to any thoughts or comments. Councilman Peterson: I understand exactly what you're saying. As I said earlier in the evening, part of what I'm sensing is, again to reiterate, south of, in 2005 MUSA we're getting things tighter than what we all perceived it to be, so I think to your point Mayor, if we can start bringing things apart, even in a little way I think it's a good thing because if you read a lot of the residents have moved out here and obviously we're talking about new residents coming in, but the ones who have moved out here, it was because they wanted more green space and they wanted homes that weren't right next to each other so. Again I'm not trying to market homes but I'm trying to address what our community's wanting. Mayor Furlong: Let me ask a question. Maybe Mr. Knutson this is a question for you. If this is being rezoned... ordinances, do we have the ability to, and maybe it would be a different type of zoning that would have... To me it sounds like a simple request but maybe it isn't. Roger Knutson: Well Mayor we were just discussing how we got here. The 5. 49 City Council Meeting — April 24, 2006 Kate Aanenson: Is the minimum. Roger Knutson: In that's the minimum allowed. Kate Aanenson: Correct. Roger Knutson: In the zoning ordinance. Kate Aanenson: That's correct. Roger Knutson: They're not asking for a variance. Kate Aanenson: No, I'm saying they're willing to do a 5 and a 10. In good faith they're willing to accept a 10 foot. A 5 and a 10 foot. As a minimum, but it's not in the zoning ordinance. We make it. Roger Knutson: You certainly can say they've agreed to do that. Can you condition it, condition a rezoning on that? No. Because that's what your zoning ordinance allows. But as part of plat approval, you're agreeing to that condition as a part of the plat approval I guess. Mayor Furlong: Is there... zoning that wouldn't throw it into variances on the lot sizes that, the lots on those setbacks? Kate Aanenson: Well if you did a PUD-R, the smallest lot would be 11, and they've got some lots that are smaller than 11,000. And they'd also have the higher impervious, which would be the 30% versus the 35. Councilman Peterson: A couple lots are at 7,000. Kate Aanenson: Correct, yeah. So it wouldn't meet that requirement, plus it would set the higher percentage for the impervious. Mayor Furlong: I thought you said right now the impervious is 35. Kate Aanenson: Correct. If you went to a PUD-R, which would be the other low density which would allow you to average the lot size to get to 15, that PUD-R zoning district requires a minimum 11,000. There's lots underneath that so that would be, it wouldn't meet that test. And then also the impervious under a PUD-R is also 30%. This is 35. Todd Gerhardt: We're still going to have to get down to see what type of model, whoever's going to ultimately own this is, what kind of model can they fit on there. It's nice that we give them, these are the parameters, you know I think is what we're establishing here. They're going to have to make their model fit to those parameters. Kate Aanenson: Correct, but if it's 5 foot, it's 5 foot. If it's a custom builder and the buyer wants a certain home plan, that's, it's a custom builder. 50 City Council Meeting — April 24, 2006 Mayor Furlong: What I'm hearing is that the 5 and 10 is something that we're requesting. Kate Aanenson: No. I'm saying I asked them if they could do a 5 and a 10 and they said they could. In good faith, but it's not, the minimum is still 5 and 5, and that's what the City Attorney is saying you can't enforce that. Councilman Lundquist: But Kate I don't see, as I'm looking through that compliance table, I don't see any lots that are less than 11,000. Councilman Peterson: I saw one at 7. Councilman Lundquist: 13, 14. 15. There's 11,050. Kate Aanenson: Also the 30% then too as opposed to the 35. They are averaging right now 19%. Mayor Furlong: And I guess you know, 30% is more important than the smaller lots than on the larger lots in terms of if it's a 12,000 foot lot... Kate Aanenson: Again that 19% was based on one builder you know using a couple different products so I don't know if you have 3 or 4 different builders, that number may jump up. Mayor Furlong: Which number is that? Kate Aanenson: If you look in the staff report on page 15. Yeah, underneath the chart we put in kind of right now it's averaging about 19%, but that was based on the previous home builder's design. Councilman Peterson: In the narrative it states the lots range from 11,050 to 22,066. Mayor Furlong: But at 98% that the average proposed coverage based upon the previous builder so then there's ... they'd have up to 30? Kate Aanenson: Correct. Todd Gerhardt: Yeah, I think that code 9,000 throws you off there. Mayor Furlong: That's the issue that ... look at. We don't deal with product design on a single family house so what we can work with is, is how they fit on the lots. Overall, like I said, you know this evening I was a little concerned about the lots and the sizes and setbacks. I'm getting comfortable with the lot sizes because of the examples given. Still not there on setbacks, and if there's something that we can do there that would give some more comfort, especially as we talk about them driving down the roads, collector roads. The roads that the neighborhood... between the homes provide greater views for people off to Bluff Creek as well. That's my issue. I think 51 City Council Meeting — April 24, 2006 if, to your point similar ... I'd be very happy to move forward. Proceeding with the rest and if we need to reduce some things or take a look at some things. Councilwoman Tjomhom: Kate, was this addressed at the Planning Commission at all? Kate Aanenson: No. Councilman Peterson: Well we create it, we do it or not. I mean. Mayor Furlong: Can we do it this evening? Is that something we can look at quickly? Kate Aanenson: Well I guess it's up to the applicant. Yeah, Mr. Chadwick. John Chadwick: Thanks for the chance to come back up here. With all due respect I wish we'd started at 5 by 5 and you'd have asked for 10 and I said sure, 10. It really gets a little tough when they ask for that, you double one side. That's okay. You double the other side, that gets a little tighter. I think there's a big streak going through here. That's an 80 footer so there's some open space there and there's a park and there's this and so I understand that people don't want to live right on their neighbors and I don't either, but I think we'll probably be okay and I hope you can have some comfort in that and you've got another couple passes at us I think before we actually start building anything. I hope that answers things. Mayor Furlong: And I appreciate that, and I guess the question is, do we have ... or not? If we approve this tonight on preliminary... Kate Aanenson: That's correct. That's correct. Roger Knutson: Mayor, if you approve it tonight this way, you can't be more restrictive later. Councilman Lundquist: But we can't approve it at 10 and 5. We can only approve it at 5 and 5 because that's the setbacks equal with the zoning. Roger Knutson: That's what your zoning ordinance provides. Councilman Peterson: Why don't we change it to a PUD. Mayor Furlong: And I guess I would then ask council if there's desire to try to do something like that... Councilman Peterson: Kate, the minimum lot size in PUD-R is what, I I? Kate Aanenson: 11,000. Councilman Peterson: So that's not an issue. Impervious surface will. 52 City Council Meeting — April 24, 2006 Kate Aanenson: Could be at 30%. It tends to be a problem in other PUD's. That's why we've moved away from doing it. The last one we ever, that we've done is Springfield because it tends to be a problem. They don't have the green space that goes beyond the entire site though too so it may work. Todd Gerhardt: You can't force a developer into a PUD situation. So they have to apply for that and have to start all over. Councilman Peterson: We couldn't do it tonight. Roger Knutson: They'd have to request. They'd have to withdraw their application and go back through Planning Commission. Kate Aanenson: Yeah, we noticed it as this. Mayor Furlong: Okay. Well that would be an over burden ... I can't see forcing that. So I guess we'll have to work on some faith that we'll have some distance between the homes. Any other discussion of council? Is there a motion? Councilman Peterson: Motion to approve subject to facts of finding supported by staff. Written in there by staff. Mayor Furlong: Is there a second? Councilman Lundquist: Clarification. Would that be all five of the motions? Kate Aanenson: Thank you. Councilman Peterson: Yep. Councilman Lundquist: Second. Mayor Furlong: Made and seconded for all five motions. Is there any discussion? Resolution #2006-31: Councilman Peterson moved, Councilman Lundquist seconded that the City Council approve the comprehensive plan Land Use Amendment from Residential — Medium Density and Office/Industrial to Residential - Low Density of the land within the Plat of Pioneer Pass except for Outlots A, B, C, D and G contingent on Metropolitan Council review. All voted in favor and the motion carried unanimously with a vote of 4 to 0. Councilman Peterson moved, Councilman Lundquist seconded that the City Council approve the Rezoning of the land within the Plat for Pioneer Pass except for Outlots A, B, C, D and G, Pioneer Pass, from Agricultural Estate District, A2, to Residential Low and Medium Density District, RLM. All voted in favor and the motion carried unanimously with a vote of 4 to 0. 53 City Council Meeting — April 24, 2006 Councilman Peterson moved, Councilman Lundquist seconded that the City Council approve Preliminary Plat for "Pioneer Pass" creating 81 lots, 9 outlots and right-of-way for public streets, plans prepared by James R. Hill, Inc., dated 213/06, subject to the following conditions: 1. The developer shall prepare a noise analysis for noise that will be generated by traffic on Highway 312 and Pioneer Trail.

COUNCIL PRESENTATIONS: Councilman Lundquist: Yes Mr. Mayor, I would like to have a discussion regarding our skate park, and I can defer if there are other members of the council that wanted to discuss other items first or we can go ahead with that. Mayor Furlong: Are there other items at this point? Other council presentations before Councilman Lundquist? Councilwoman Tjornhom: No. Councilman Lundquist: Well first let me say thanks to Sergeant Olson and Mr. Hoffman that hung around until 20 after 10:00 to talk about that because they're two of the key parties and I really do want your input and your thoughts, so thank you for that. Been an ongoing issue or challenge probably since it was built. Continue to have some things going on out there that are just items in my personal view that, or occurrences that I would rather not see. Last week we had another incident on or around the skate park that concerns me from a safety of the people using it standpoint. So what I want to discuss tonight, amongst the council members with some input from staff and especially from Todd and Sergeant Olson is, I feel like that we haven't solved the problems at the skate park. We still have instances of things going on out there with litter and the foul language. We've had some acts of violence out there now. We've got tobacco use and all that other stuff going on. We've tried various measures of closing it down, and you know I know that Mr. Gerhardt and Mr. Hoffman and the deputies have put their time, especially Todd and Todd to go out and try to rectify those situations through, how shall we say you know gentle persuasion. And you know, with limited success I think so, I look at that. It's, you know you get a collector of people together, especially when you're talking about pre -teens. Teens and there's some older people that use that as well, but anytime we get a collection of people together unsupervised... that are undesirable, I look at it as an overwhelming majority of people that are using that space out there are doing it for the, are using it as intended. We've got a lot of kids out there riding their skate boards. We'd absolutely rather have them riding them there than on the front steps of the library or you know in front of the businesses downtown and all of that so, I want to have that amenity. But I want to ensure that we're, that we as a city are providing a safe amenity as well. And an amenity where parents can feel confident that they're sending their kids out there and they're not going to be subject to you know violence. They're not going to be subject to you know some of the other things that are going on out there. Things like that are going to happen. Kids face all kinds of challenges, realize that but I can't, I have a problem sitting and knowing that those things are going on and we continue I think to do the same things over and over, and I feel like as a council we need to have a discussion to talk about if we're providing the right resources to staff or the right direction to staff or what else is there out there -o9 Planning Commission Meeting —April 4, 2006 PUBLIC HEARING: CONDITIONAL USE PERMIT FOR DEVELOPMENT WITHIN THE BLUFF CREEK OVERLAY DISTRICT WITH A VARIANCE FOR ENCROACHMENT INTO THE TRAIL (1600 PIONEER TRAIL) AT FUTURE HIGHWAY 312, PLANNING CASE NO. 06-09, APPLICANT D.R. HORTON. Public Present: Name Address Joel Cooper SEH Paul Bilotta 1641 Chatham Avenue, St. Paul 55112 John Chadwick 11430 Zion Circle John and Joe Knoblauch 1450 Knob Hill Lane, Excelsior Sever Peterson Eden Prairie Bob Generous presented the staff report on this item noting that D.R. Horton has withdrawn and assigned the application to the property owner, Sever Peterson. Sacchet: Thank you Bob. Questions from staff. Mark, go ahead. Undestad: One quick one Bob. Can you show on that plan again, you said that the road will cut Outlot A, it will split Outlot A when that goes in. Where is that? Generous: It's approximately here. It comes down and then. Undestad: And that's Liberty at Creekside? Generous: Liberty at Creekside here. So between their property and the Degler property there's a small piece of right-of-way that would need to be dedicated. The developer would only provide the right-of-way and any necessary easements for it's construction. Town and Country Home would be responsible for it's construction. Undestad: Thank you. Sacchet: Kurt, c e� SCMMEo Planning Commission Mee — April 4, 2006 • Papke: The access to Pioneer Trail, so there's an overpass that would have to be constructed to get there? How do you get to Pioneer Trail? I'm a little bit confused. Generous: It will be at grade that come down because the freeway will actually be south of Pioneer here. ...will go to the north. Papke: Okay, it crosses over there. Generous: The excess right-of-way is, none of that area is for potential river crossing also, so there could be additional ramping. That has to be resolved with MnDot yet. They're doing the Environmental Impact Statement now and it's going through that process. They have this six corridors I believe and they're trying to get that down to one and then adopt that so that the local communities can do the official mapping. Sacchet: In terms of the comprehensive plan ... requiring a comprehensive plan amendment. So are we actually deviating from the original idea of the comprehensive plan? Can you clarify that please. Generous: Well the comprehensive plan currently guides the property for medium density residential or office industrial uses, neither of which would be consistent with single family detached housing. So to do this development, and based on the original, the concept approval that was given for the planned development a year ago, this is one, a way that we saw that they could do it through this zoning with the land use amendment. Sacchet And then the other question with storm water pond. It seems like there were two options given. One in the primary zone and one not. Generous: Correct. Sacchet: If you could elaborate a little more because I think it's staffs finding that they were not in the primary zone would be more hazardous or less ideal than the one in the primary zone. Is that something for you Alyson? Fauske: Staff worked with the developer... preliminary plat submittal, we went around and around on this issue. Basically what it came down to planning commissioners that when we looked at ... erosion, the erosion potential of that pond outletting within that primary zone... we felt that it was a better place than that pond... Sacchet: Overall a better solution. And then I have a detail question. Condition 8 of the preliminary plat approval for recommendation. Talks about the 950 contour. Is that the border of the primary zone or why is 950 essential? Generous: It's for, to provide screening from the road at the round about I believe. Sacchet: I didn't understand that one. 37 C ... Planning Commission Meeting — April 4, 2006 Generous: Yeah, so that they can get some berming Sacchet: It's a berming situation? Generous: Yeah. Sacchet: Okay. And so we, I didn't see much detail about the wetland replacement plan. That's something that still needs to be worked out? Generous: Yes. They submitted the initial stuff in that and that has a dual tracking process. It's going through the technical committee reviews. Sacchet: Okay. So that's still being worked? Generous: Yes. Sacchet: Okay. Alright, if there's no more questions for staff, I'd like to invite the applicant. If you want to come forward and tell us who you are and what you want to add to what staff presented to us. Maybe we'll have some questions for you. We'll see. John Chadwick: Thank you. My name is John Chadwick. I reside at 11430 Zion Circle, Consultant on behalf of the Peterson Family. Sever Peterson is here. Our planning consultant Paul Bilotta is with us and also Joel Cooper from the Hill Engineering Firm. Here to answer questions. Certainly thank you for all your consideration to date. Enjoy being here again. If you didn't remember me I was here in August so that's who I am. Thank you. Good to be back. Sacchet: So you don't have any particular issues? Everything's cool for you. John Chadwick: No, and Joel's been through all the engineering comments and, well all the comments. We've been working on this for quite some time. Sacchet: Okay. Do we have questions? Yes Jerry, you have a question for the applicant. McDonald: For the applicant. I'm confused as to who's doing the development. D.R. Horton was part of this and they're no longer in it. Who's the, you know the general contractor doing all the work and everything. Are you all doing that yourself or? John Chadwick: Weird question. The Horton folks and our folks parted company today at about 5:30 and so I don't have a specific answer for that. Certainly who the general contractor would be, even in their case they wouldn't be getting into who's going to do the grading, etc until they put it out for bid so, I'm sure with lot prices that will be there, we'll have a number of quality builders. As a matter of fact there's one here in the audience now. So I'm sure there's going to be some wonderful people stepping forward. McDonald: Okay. im Planning Commission Meeting — April 4, 2006 Sacchet: Alright, thank you very much. Now this is a public hearing. If anybody wants to address this item, please come forward and let us know if you have something to say. Seeing nobody get up, I'll close the public hearing and bring it back to the commission for discussion and comments. Discussion. Comments. Anybody? McDonald: Well I guess I've got a question. And maybe this is nothing but, we've got a very detailed plan here that was put together based upon two applicants getting together. If it now comes back to somebody else, can the plan change? If we do a PUD and they want to do something different with the number of lots or how, you know once we do this, is this it? Generous: Unless they come back with a whole new plan and start the process over. But it's like property owners all the time bringing a subdivision request. It's reviewed and then they'll sell it off to builders or developers in the future. In this instance they had D.R. Horton that started the process. They're withdrawing as the applicant. However they've assigned their rights if you will to this development plan to the property owner and he's going, wants to take it forward. Sacchet: So it's simple. Generous: Nothing changes as far as the plans are concerned. Sacchet: And if they would change it... Generous: They would have to come back, yeah. McDonald: Okay. I have no other comments or questions. Sacchet: Alright. If there's no questions, comments, we've just got to make some motions. Motions with lots of conditions. Page 16 I think is where it starts. Generous: 16 through 22. Larson: A, Band C? Generous: And D. Sacchet: A, B, C, D and E. Larson: Alright, I'll make a motion. I'll make an attempt anyway.

Go ahead Kurt. Papke: I'd like to make a friendly amendment that condition, or motion C. The plans are prepared not by the robber baron of the north, but rather by James R. Hill. Sacchet: Is that acceptable Debbie? Larson: Yes. Sacchet: I had a friendly amendment too. To the part E. I would like to specify encroachment to the primary zone to construct a storm water pond, as shown in the plans and specified the date whatever so we know it's in the plan.

The amendment proposes to change the land use designation for approximately 42 acres located north of Pioneer Trail at future highway 312 from Medium Density Residential and Office/Industrial to Low Density Residential. The net density of the project is 2.88. City's average density since 2000 has been 5.1. As the parcel is less than 80 acres and under 100 units proposed, the amendment meets the administrative review waiver guidelines. Council staff finds that the amendment is in conformance with metropolitan system plans, consistent with the Regional Development Framework, and has no impact on the plans of other units of local government. Council staff also finds that this amendment meets the Comprehensive Plan Amendment Administrative Review Guidelines adopted by the Council on May 11, 2005. Therefore, the Council waives further action on this review and the City may place this amendment into effect immediately. The amendment, explanatory materials supplied and the information submission form will be appended to the City's Plan in the Council's files.

I am forwarding the corrected disposition details for the outlots as follows: Developer — Pioneer Pass, LLC Original fee owner — Peterson -Jacques Farms Outlot A — Due to the fact that this parcel was assessed for special assessments as part of the Bluff Creek Blvd project it is our intent to plat it as an outlot and negotiate a sale of the outlot to Town & Country so they can incorporate it into their plat as road right-of-way. So until that transaction is completed with Town & Country the ownership will remain with the Developer. Outlot B and E — The ownership of these outlots will initially remain with the Original fee owner. It is their intent to donate both parcels to the City for open space and to qualify for a charitable donation of the property. Bruce Odlaug, Sever's attorney will be in contact with you with more details. Outlot C — Ownership will be with Developer, and is to be platted as the second phase of the development. Outlot D — Ownership will initially remain with the Original fee owner, with the outlot being deeded to the City for park dedication purposes as part of the final plat recording. The payment amount indicated in the preliminary plat approvals for the park property in excess of the required dedication will be paid to Peterson -Jacques Farms. Outlot F and G — will be deeded to the City as part of the plat for storm water ponding. Please call if you have any questions on the above. I did also confirm with David Braslau Associates that he will have a completed noise study to you by this Friday. I would also appreciate feedback on the revised street names as soon as you can so I can update the plat.

At present, I am assuming the following: Outlot A will be dedicated to the City for future right-of-way. (connection to Liberty at Bluff Creek) Outlot B will be retained by the developer. (Bluff Creek Primary zone and storm water pond) Outlot C will be platted in the future. Outlot D will be dedicated to the City for a future park. Outlot E will be retained by the developer. (Bluff Creek Primary zone) Outlot F will be retained by the developer. (storm water pond) Outlot G will be retained by the developer.

Project Location: Pioneer Pass (Peterson Parcel) (NW'/4 Section 26 and NE 1/4 Section 27, Township 116N, R23W) Type of Application (check one): ❑ Delineation Decision ❑ Exemption Decision ❑ No Loss Decision ❑x Replacement Plan Decision ❑ Banking Plan Decision Date of Decision: May 26, 2006 Findings and Conclusions The City of Chanhassen, LGU, has made a replacement plan decision approving the wetland Impacts associated with the Pioneer Pass development in the Chanhassen 2005 MUSA area. Impacts are limited to filling of type 1 wetland basin I (.47 acres). Replacement wetland will be created on site with .48 acres of New Wetland Credit and 1.22 acres of Public Value Credit. The applicant considered the no -build option as well as the total avoidance option in sequencing discussions, however both were dismissed as infeasible. Wetland I is considered a severly degraded basin due to a high level of disturbance and farming activities that have historically occurred around and through the basin. The basin is also predominately fed by surface water which will be cut off during the development of the site. CITY OF CHANHASSEN By:✓T_ a �� Title: Natural Resource Technician Date: 5/26/2006 Aanenson, Kate From: Fauske, Alyson Sent: Wednesday, June 21, 2006 9:15 AM To: Oehme, Paul Cc: Aanenson, Kate Subject: Outlot B Peterson property Streets The preferred access alignment would be from the minor collector that will be built with the single family development and will connect to Pioneer Pass. This is preferred since access to Pioneer Trail should be limited and the slopes are gentler at this location. An alternative access would be from Pioneer Trail, approximately 700 feet east of the Pioneer Pass minor collector connection. This access aligns with the ROW piece between Lots 19 and 20, Block 1 and Outlot B. Slopes are an issue at this location. Sanitary Sewer The preferred sewer service location for Outlot B is from Lot 19, Block 1. The invert to Outlot B would be approx. 910', which is 20' deep, but quickly shallows due to topography. Outlot B will likely need to be served by a lift station. If MNDOT turns back some of the ROW north of Pioneer Trail, there may be enough developable area south of the Pioneer Pass development and Pioneer Trail. Sanitary sewer should be stubbed between Lots 23 and 24, Block 1. The invert elevation at the stub would be approx. 911.6', or approx. 14.5' deep. This sewer could be extended to the west should this area south of the Pioneer Pass plat become developable. This stub can be installed in lieu of the one shown between Lot 28 and 29, Block 1 of the preliminary plat, which is undesirable since it would run under a storm water pond. Water Based on the area of Outlot B (4.13 acres per preliminary plat) and the zoning, watermain should be looped. Eight inch water should be stubbed between Lots 20 and 21, Block 1. If the street access extends from the minor collector, water would be extended from the minor collector to provide looping. An 8" stub should be installed just south of the Pioneer Pass property line to provide the most flexibility for extending the watermain since it is unknown how much, if any of the MNDOT ROW will be turned back. If the street access extends from Pioneer Trail the watermain for Outlot B would have to loop back into the Pioneer Pass development. The location of this second loop should be chosen so that utilities will not lie on both sides of a lot lie 10' wide sideyard D&U on both sides of the lot), but this may be inevitable. Under this scenario, it may be best to loop between Lots 19 and 20 and Lots 20 and 21, Block 1 since these are longer lots lie more buildable area at the back) and close to Outlot B.

The grading plan shows retaining walls in different areas. The applicant must be aware that no retaining walls are allowed within any drainage and utility easement. Building permits are required for all retaining walls and must be designed by a Structural Engineer registered in the State of Minnesota. The City of Chanhassen • A growing community with clean lakes, quality schools, a chaning downtown, thriving businesses, winding trails, and beautiful parks. A geat place to live, work, and play. Bob Generous Peterson Property Preliminary Plat Review March 1, 2006 Page 2 of 7 Runoff from the northern half of the site currently drains toward the wetland on the northeastern corner and the southern half of the site drains toward the wetland on the southwestern comer. The northern portion of the site drains to proposed Pond #2 (Outlot A), which outlets to the wetland on the north property line. Runoff from the remainder of the site will be conveyed to ponds within Outlots E and F, which outlet to the existing wetlands on the southwest corner of the site and eventually to Bluff Creek. The developer's engineer has submitted hydrology calculations for the site. Staff will review the calculations and forward any recommendations with the final plat report. Storm sewer calculations and a drainage map must be submitted with the final plat application. The storm sewer must be designed to accommodate a 10- year, 24-hour storm event. Additional stormwater catch basins must be added in the back yards of Lots 1-15, Block 3, along Street A in front of Lots 25-28, between Lots 15 & 16 and 4 & 5, Block 1, and the catch basin between Lots 6 & 7 must be built with two inlet openings. The last public stormwater structure that is road -accessible prior to discharging to a water body must have a 3-foot sump. The style of home and lowest floor elevation must be noted on the final grading plan. The back yard lowest entry for any house adjacent to a stormwater pond must be a minimum of three feet higher than the pond high water elevation. The final grading plan must also include a note to remove the existing driveway at Pioneer Trail. A minimum 75-foot long rock construction entrance must be shown on the plans. In addition, tree preservation fencing must be installed at the limits of tree removal. An easement is required from the appropriate property owner for any off -site grading. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes. UTILITIES Trunk sanitary sewer and watermain to serve the proposed development will be constructed with the 2005 MUSA Expansion Improvements, City Project 04-05. The developer's engineer must ensure that the proposed location of the sanitary sewer and watermain and the elevation for the sanitary sewer connection shown on the Peterson Property utility plan coincides with City Project 06-05, Bluff Creek Boulevard Improvements, utility plan. Bob Generous Peterson Property Preliminary Plat Review March 1, 2006 Page 3 of 7 Lateral sanitary sewer and watermain within the development will extend from the trunk facilities. Staff is concerned with the proposed sanitary sewer connection to the trunk which is more than 40 feet deep along Street A at Block 1, Lots 1-5. The applicant must revise the plans and reroute the sewer to minimize the depth of the sewermain. The developer shall work with the City and the City's consultant for the Bluff Creek Boulevard improvements to reroute this sewer to an acceptable location. Also, the sewer line that runs through Stormwater Pond E needs to be moved outside the ponding limits. Watermain within Street D must be 12-inch DIP. The City will reimburse the developer the cost difference between 8-inch lateral and 12-inch trunk watermain. In -home pressure reducing water valves may be required for some lots. Utility services for the lots must be shown on the final utility plan. Installation of the private service utilities for the site will require permits and inspections through the City's Building Department. The 2005 MUSA feasibility study, which was approved by the City Council, listed an assessment to the underlying property. These assessments are for proposed trunk sanitary sewer, storm sewer, watermain, and road improvements. Since the developer will be responsible for extending lateral sewer and water service to the lots, the sanitary sewer and water connection charges will be waived. The property is subject to sanitary sewer and water hookup charges for all of the lots. The 2006 trunk utility hook-up charges are $1,575 per unit for sanitary sewer and $4,078 per unit for water. The 2006 SAC charge is $1,625 per unit. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be aware that all public utility improvements will require a preconstruction meeting before building permit issuance. Permits from the appropriate regulatory agencies will be required, including the MPCA, NPDES, Dept. of Health, Carver County, MnDOT and Watershed District. Access to Outlot B has been severed by MnDOT. Outlot B has a different zoning than the development area. The developer should work with the City to provide service stubs for the future development of the site. STREETS The site plan shows the current alignment of the north -south collector road and a roundabout per Kimley-Hour's design and report for City Project 06-05. The r Bob Generous Peterson Property Preliminary Plat Review March 1, 2006 Page 4 of 7 easterly half right-of-way of the north -south segment of the collector street lies within the Peterson Property development. The remaining westerly portion will be within the Liberty on Bluff Creek development. Right-of-way will be dedicated for the roadways. Public streets extending from the north -south collector include Streets A, B, C and D. Streets A, B, C and D will be a 31-foot wide back-to-back street within a 60- foot wide right-of-way. Street Bends with a 91-foot pavement radius cul-de-sac within a 120-foot radius right-of-way. Street D will intersect Pioneer Trail south of the property as part of MnDOT's Trunk Highway 312 and be 36-feet wide with an 80-foot wide right-of-way. The access for the minor collector road within the development (Street D) does not appear to line up with MnDOT's access management point at the property line. The developer will need to work with MnDOT to have the access point moved. Please contact Steve Charmer with MnDOT at 651-582-1272 to move the access point. Street C is 31 feet wide. Access to Outlot B has been served by MnDOT. Outlot B has a different zoning than the development area. Access to Outlot B has not been determined at this time. The developer should work with MnDOT, the County and the City to determine future access to the site. The applicant must be aware that adjacent property at the northeastern corner of Peterson property has submitted a site plan (Liberty at Creekside) showing a street going through outlot (A) and intersecting with the future extension of Audubon Road. As to that, the applicant must coordinate with the adjacent property developer and need to dedicate the public street right-of-way. An Arterial Collector Roadway Fee in the amount of $2,400/developable acre will need to be paid at the time of final plat. RECOMMENDED CONDITIONS OF APPROVAL 1. Before site grading commences, the existing building and driveway access off Pioneer Trail onto the property must be removed. 2. On the grading plan, add a note to remove any existing house and driveway access. The developer's engineer must work with Liberty on Bluff Creek's engineer to ensure that the proposed grading on each property matches at the property line. 4. Ground slopes shall not exceed 3:1.

Surveys • Please identify the B-corners and in -place monumentation in the final plat. For questions concerning this request, please contact Bruce Wetherbee (763-797-3110) of Mn/DOT's Surveys Section. Residential Noise Statement Mn/DOT'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 An equal opportunity employer Development, and the U.S. Department of Transportation. Minnesota Rule 7030.0030 states that municipalities are responsible for taking all reasonable measures to prevent land use activities listed in the MPCA's Noise Area Classification (NAC) where the establishment of the land use would result in violations of established noise standards. Mn/DOT policy regarding development adjacent to existing highways prohibits the expenditure of highway funds for noise mitigation measures in such areas. The project proposer should assess the noise situation and take the action deemed necessary to minimize the impact of any highway noise. If you have any questions regarding Mn/DOT's noise policy please contact Peter Wasko in our Design section at (651) 582-1293. As a reminder, please address all initial future correspondence for development activity such as plats and site plans to: Development Review Coordinator Mn/DOT - Metro Division Waters Edge 1500 West County Road B-2 Roseville, Minnesota 55113 Mn/DOT document submittal guidelines require three (3) complete copies of plats and two (2) copies of other review documents including site plans. Failure to provide three (3) copies of a plat and/or two (2) copies of other review documents will make a submittal incomplete and delay Mn/DOT's 30-day review and response process to development proposals. If you happen to know the property identification number, please include that information with your submittals. We appreciate your anticipated cooperation in providing the necessary number of copies, as this will prevent us from having to delay and/or return incomplete submittals.

Pioneer Pass/Chanhassen, Minnesota Traffic Noise Assessment 1.0 INTRODUCTION 1.1. Study Objectives and Project Location This noise assessment reports on projected traffic noise levels at the Pioneer Pass development in Chanhassen, Minnesota, that will be located south of Bluff Creek, west of the newly constructed TH 212, and north of the realigned Pioneer Trail. Location of the site relative to Bluff Creek, the future TH 212 and Pioneer Trail is show in Figure 1.1. The assessment addresses compliance of the project based on the Minnesota Noise Standards. 1.2. Minnesota Noise Standards The Minnesota noise standards for different land uses are presented in Table 1.1, with those for residential land use (which apply to the Pioneer Pass development) shown in bold type. The L10 metric represents the noise level not to be exceeded for 101/6 or six minutes of an hour. The L50 metric represents the level not to be exceeded for 50% or 30 minutes of an hour. Table 1.1 Minnesota State Noise Standards Noise Area Classification Daytime (0700-2200) Sound levels in dBA Nighttime (2200-700) Sound levels in dBA Noise Metric L10 L50 L10 L50 1 residential 65 60 55 50 2 commercial 70 65 70 65 3 industrial 80 75 80 75 Source: Minnesota Rules 7020.0040 Under exceptions contained in Minnesota Rules, commercial noise standards (NAC-2) or an L50 of 65 dBA can be applied to a residential land use providing the provision in the rules can be met. The applicable provisions of Minnesota Rule 7030.0050 are presented below. Subp. 3. Exceptions. The noise area classification for a land use may be changed in the following ways if the applicable conditions are met. B. The standards for a building in a noise area classification 2 shall be applied to a building in a noise area classification 1 if the following conditions are met: (1) the building is constructed in such a way that the exterior to interior sound level attenuation is at least 30 dB(A); (2) the building has year-round climate control; and (3) the building has no areas or accommodations that are intended for outdoor activities. Any new home constructed to comply with the Minnesota energy code will likely comply with the first two conditions listed above. Outdoor areas associated with homes are not normally intended for use between 6-7 am when the highest "nighttime" levels occur. David Braslau Associates, Inc. Page I Pioneer Pass/Chanhassen, Minnesota Traffic Noise Assessment 1.3. Report Structure Section 2.0 of this assessment describes the information and data sources used in noise level prediction and analysis. Section 3.0 describes noise modeling assumptions. Section 4.0 presents the noise modeling results. Section 5.0 discusses sound attenuation required to comply with the Minnesota noise standards and HUD guidelines. Section 6.0 contains a summary of findings and conclusions. David Braslau Associates, Inc. Page 2 a Pioneer Pass/Chanhassen, Minnesota Traffic Noise Assessment 2.0 DATA SOURCES USED FOR THE ANALYSIS 2.1. Information on the Proposed Project Information on the proposed project that has been provided by Terry Schneider of Project Development, Inc. include the following: • General project location • Site layout relative to the adjacent roadways • Grading and drainage plan that includes pad elevations of proposed buildings 2.2. Previous information on the Project Site Highway geometry and elevation data were obtained for a previous study to assess potential noise levels on the proposed project in discussions with MnDOT with reference to the Sever Peterson property. There is no warranty expressed or implied by Sever Peterson as to the applicability of these data for use other than its original purpose. However, the previous grading plan for the Peterson property has been superceded by the new grading plan Pioneer Pass and has been used for the analysis and prediction of traffic noise levels in this Pioneer Pass noise assessment. 2.3. TH 212 Traffic Projections Future traffic projections for 2007 and 2025 by MnDOT were available from a previous air quality analysis update for the TH 212 corridor. David Braslau Associates, Inc. Page 4 Pioneer Pass/Chanhassen, Minnesota Traffic Noise Assessment 3.0 TRAFFIC NOISE MODELING ASSUMPTIONS Roadway elevations as well as detailed topographic data previously provided by RLK were used in conjunction with the Final 50 Scale Grading Plan for Pioneer Pass, LLC, as input into the traffic noise model. Roadway traffic volumes used for the AM (6-7 AM) and PM Peak Hour are shown in Table 3.2. Table 3.1 Assumed AM and PM Traffic Volumes on TH 212 (vph in 2025) PM Percent NB SB Cars 90 1357 3006 MT 4 60 134 HT 6 90 200 AM Percent NB SB Cars 90 1803 814 MT 4 80 36 HT 1 61 1201 54 A speed of 65 mph was assumed on TH 212 Two-way roadway volumes on Pioneer Trail based upon traffic flow data and are shown in Table 3.2. Table 3.2 Assumed AM and PM Traffic Volumes on Pioneer Trail (vph in 2025) PM Percent Two-way Cars 95 1330 MT 2 28 HT 3 42 AM Percent NB Cars 95 798 MT 2 25 HT 3 1 17 A speed of 55 mph was assumed on Pioneer Trail. Based upon the topographic and grading information provided, some limited shielding of the homes by the TH 212 cut was included in the noise model as a topographic noise barrier. Thirteen lots that are closest to Pioneer Trail and TH 212 were used to assess potential noise impacts on the project. Homes further from these roadways will be shielded by this first row of homes and will have levels that are at least 4 to 5 dBA lower. Receptors on the ground and upper floor of a home on each block were assumed. The receptor site locations are shown in Figure 3.1. David Braslau Associates, Inc. Page 5 Pioneer Pass/Chanhassen, Minnesota Traffic Noise Assessment 4.0 TRAFFIC NOISE MODELING RESULTS 4.1. PM Peak Hour Traffic Noise Levels Predicted PM Peak Hour traffic noise levels (year 2025) at the ground floor or walkout level (representing persons standing at ground level outside of the buildings) are shown in Figure 5.1. It can be seen that the ground level receptor sites are predicted to be in compliance with the Minnesota noise standards in the year 2025. 4.2. AM (6-7 AM) Traffic Noise Levels Predicted AM (6-7 AM) traffic noise levels (year 2025) at the upper level (representing sleeping rooms) are shown in Figure 5.2. The LIO 55 are above the nighttime standards. This is a common occurrence along all major highways in the Twin Cities Metropolitan Area. However, under the MPCA rule exceptions, as noted in Section 1.2, the higher NAC-2 standards can be applied providing a 30 dBA attenuation is provided by the walls along with year-round climate control. This is discussed in Section 6.1 below. David Braslau Associates, Inc.

TRAFFIC NOISE ASSESSMENT Upper Floor L10 Levels (AM) Pioneer Pass/Chanhassen, Minnesota Traffic Noise Assessment 5.0 NOISE ATTENUATION REQUIREMENTS As noted above, the MPCA rules will require a 30 dBA exterior -to -interior noise attenuation for the residential buildings in the Pioneer Pass development that are adjacent to TA 212 and Pioneer Trail. For construction that complies with the Minnesota Energy Code, insulating windows are needed as well as insulated walls. The minimum STC rating generally encountered for new insulating windows in Minnesota is STC 28. STC is the Sound Transmission Class that specifies how much sound attenuation is provided by a window or a wall. Typical wall construction with 2x6 studs provides an STC 40 wall with 2x4 studs providing an STC 39 wall. Typical bedrooms do not have more than 20% window area. With these assumptions and a 3 dBA correction factor to reflect traffic noise, the 30 dBA exterior -to -interior noise attenuation would be achieved. In addition to the proposed wall construction and windows, normal good building practices to ensure adequate sound attenuation such as shielding or appropriately routing through -the -wall vents and adequately caulking windows and other openings will be required. David Braslau Associates, Inc. Page 10 Pioneer Pass/Chanhassen, Minnesota Traffic Noise Assessment 6.0 FINDINGS AND CONCLUSIONS A traffic noise assessment has been completed for the Pioneer Pass development based upon the MPCA noise standards. The assessment has been based upon 2025 traffic projections by the Minnesota Department of Transportation (MnDOT) for the future TH 212 corridor passing through Chanhassen, Minnesota. Roadway elevations, topography and pad elevations have been based upon previously provided data and the Final 50 Scale Grading & Drainage Plan for Pioneer Pass. Vehicle mix has been based upon data from other studies along TH 212 in the study area. Receptor sites have been assumed on the fast and second floors of each of the proposed residential buildings adjacent to the future TH 212 right-of-way and Pioneer Trail. Traffic noise predictions have been made taking into account the roadway and traffic parameters as well as shielding by topography due to the TH 212 cut. Predictions of noise levels (I.10 or the level exceeded 10% of the hour) were made for the worst "nighttime" hour, or 6-7 AM, and the PM Peak Hour. In the year 2025, predicted L101evels at the ground or walkout level are in compliance with the daytime noise standards, while the upper level or sleeping room level are above the nighttime standards, but by less than 10 dBA. However, under the MPCA rule exceptions, the higher NAC-2 standards can be applied providing a 30 dBA attenuation is provided by the building along with year-round climate control. Typical building construction should provide the needed 30 dBA noise attenuation required by MPCA rules when the nighttime level exceeds 55 dBA by no more than 10 dBA. y:\jobs\2006jobs\206089\pioneerpms-noisemsessment.dm David Braslau Associates, Inc. Page 11 The applicant shall coordinate with the developer of the adjacent properties in the northeast comer of the site the dedication of public street right-of-way to provide access from the parcel to the north to the parcel to the east and revise the plans accordingly From: Terry Schneider [mailto:terryschn@qwest.net] Sent: Wednesday, September 13, 2006 9:04 PM To: Generous, Bob Cc: Roosteoec@aol.com; Bruce Odlaug; John Chadwick; John Knoblauch; Jeff Williams; Paul Bilotta; Oehme, Paul; Joel Cooper Subject: RE: Pioneer Pass - disposition of Outlots Bob, I am forwarding the corrected disposition details for the outlots as follows: Developer — Pioneer Pass, LLC Original fee owner — Peterson -Jacques Farms Outlot A — Due to the fact that this parcel was assessed for special assessments as part of the Bluff Creek Blvd project it is our intent to plat it as an outlot and negotiate a sale of the outlot to Town & Country so they can incorporate it into their plat as road right-of-way. So until that transaction is completed with Town & Country the ownership will remain with the Developer. Outlot B and E — The ownership of these outlots will initially remain with the Original fee owner. It is their intent to donate both parcels to the City for open space and to qualify for a charitable donation of the property. Bruce Odlaug, Sever's attorney will be in contact with you with more details. Outlot C — Ownership will be with Developer, and is to be platted as the second phase of the development. Outlot D — Ownership will initially remain with the Original fee owner, with the outlot being deeded to the City for park dedication purposes as part of the final plat recording. The payment amount indicated in the preliminary plat approvals for the park property in excess of the required dedication will be paid to Peterson -Jacques Farms. Outlot F and G — will be deeded to the City as part of the plat for storm water ponding. Please call if you have any questions on the above. I did also confirm with David Braslau Associates that he will have a completed noise study to you by this Friday. I would also appreciate feedback on the revised street names as soon as you can so I can update the plat.

At present, I am assuming the following: Outlot A will be dedicated to the City for future right-of-way. (connection to Liberty at Bluff Creek) Outlot B will be retained by the developer. (Bluff Creek Primary zone and storm water pond) Outlot C will be platted in the future. Outlot D will be dedicated to the City for a future park. Outlot E will be retained by the developer. (Bluff Creek Primary zone) Outlot F will be retained by the developer. (storm water pond) Outlot G will be retained by the developer. (storm water pond) Outlots B and E, if retained by the developer, will need conservation easements recorded against them. Drainage and utility easements must be recorded over all of Outlots B, E, F, and G. Please let me know if these assumptions are correct. We would like to complete our review by this Fri. Bob JAMES R.
