A rezoning must be consistent with the City’s Comprehensive Plan. The City’s discretion in approving or denying a preliminary plat is limited to whether or not the proposed plat meets the standards outlined in the Subdivision Regulations and Zoning Ordinance. If it meets these standards, the City must approve the preliminary plat. This is a quasi-judicial decision. The City’s discretion in approving or denying a Variance is limited to whether or not the proposed project meets the standards in the Zoning Ordinance for a variance. The City has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi-judicial decision. The City’s discretion in approving or denying a Variance in conjunction with a subdivision is limited to whether or not the proposed project meets the standards in the Subdivision Ordinance for a variance. The City has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi-judicial decision. Notice of this public hearing has been mailed to all property owners within 500 feet. PROPOSAL/SUMMARY The applicant is requesting rezoning of a portion of the property from Agricultural Estate District, A2, to Single-Family Residential District, RSF; subdivision approval to create 21 single-family lots with variances for street widths, street frontages on some lots in Block 1, and wetland setback on Lot 1, Block 1; seven Outlots and right-of-way for public streets. The applicant held neighborhood meetings with the West 96th Street residents on Saturday, July 10, 2021 and the Foxwood and Pioneer Hills neighborhoods on Wednesday, July 14, 2021. APPLICABLE REGULATIONS Chapter 18, Subdivisions Chapter 20, Article II, Division 3. Variances Chapter 20, Article XI, “A2” Agricultural Estate District BACKGROUND On January 25, 2021, City Council approved the Interim Use Permit to allow site grading to create an open water wetland. The project began this winter, but due to warm weather, could not be completed. Erhart Farm – 775 W. 96th Street July 20, 2021 Page 3 On August 14, 2020, the Chanhassen City Council approved the adjustment to the Bluff Creek Overlay District (BCOD) Primary Zone boundary to encompass the additional 3+ acre area adjacent to Highway 212 in Oultot G. (Planning Case #2020-13) On July 7, 2020, the City of Chanhassen received a complete Wetland Delineation Report for the property and a Notice of Application was sent on July 15, 2020. The on-site Technical Evaluation Panel (TEP) was held on July 29, 2020 in order to review the wetland boundaries and types. The wetland types that were delineated on the property were Types 1, 2, 3, 5, and 6. The TEP and Local Government Unit (LGU) concurred with the boundaries and types and the Notice of Decision was issued on August 8, 2020. As part of the 2040 Comprehensive Plan adopted on February 10, 2020, the City approved a three acre Land Use amendment from Residential Low Density to Office in the western portion of the parcel encompassing the area adjacent to Highway 212 in Outlot G. In 2008, as part of the City’s 2030 Comprehensive Plan, the City approved a Land Use amendment of the westerly 10 acres of the property from Residential-Low Density to Office. On October 23, 2006, the Chanhassen City Council approved Wetland Alteration Permit #06-32 for the construction of an access road and stormwater pond. The wetland mitigation for this is located Outlot G north of the large wetland complex On July 10, 1995, the City Council approved the preliminary and final plat of Butternut Ridge Addition, Subdivision #95-9, creating one lot and one outlot. This subdivision permitted the property owner to sell the 2½-acre home site on the property and keep the balance of the site for the owner’s personal use and future development. The property owner still owns the home on the property. EXISTING CONDITIONS The developer provided an existing condition survey of the entire 117.14 acre property which included the field surveyed area of approximately 17.6 acres proposed to be developed (Blocks 1 and 2, Outlots A, B and C, and all newly dedicated right-of-way) and is in general conformance with the requirements of Sec. 18-40. The remaining 117.14 acres not surveyed will be field surveyed at the time of future development. A single-family residence with a barn exists within the proposed development and is proposed to remain as Lot 5, Block 2. As such, the developer is proposing to vacate the public drainage and utility easements (DUE) associated with the existing residence and record adjusted public DUE with the proposed plat. This public DUE, along with all other easements identified within the platted area, must be vacated before the City Council considers final plat approval. The additional easements to be vacated include those identified on the existing condition survey (per document numbers; A186881, A509111, A94210, A651406, etc.). Additionally, the developer will be required to obtain any necessary right-of-way easements for the extension of W. 96th Erhart Farm – 775 W. 96th Street July 20, 2021 Page 4 Street from abutting properties. Lastly, the driveway to the existing residence must be surfaced with bituminous, concrete or other hard surface materials in accordance with Sec. 20-1122 of City Ordinance. SITE CONSTRAINTS Wetland Protection There is are multiple wetlands located on the property. Bluff Creek Overlay District Outlot G is bisected by the Bluff Creek Primary Zone. Bluff Protection There are no bluffs on the property. Shoreland Management The property is not located within a Shoreland Overlay district. Floodplain Overlay This property is not within a floodplain REZONING The existing zoning of the property, Agricultural Estate District, is not consistent with the Land Use designation of the property, Residential Low Density. The Comprehensive Plan allows less intensive land uses to remain in place. However, any approval by the City for development of the property must be consistent with the Comprehensive Plan. The following zoning districts are consistent with a Residential Low Density land use: RSF (Residential Single Family), R4 (Mixed Low Density), RLM (Residential Low and Medium Density), or PUD-R (Planned Unit Development Residential). The proposed rezoning to Single-Family Residential District (RSF) is consistent with the Comprehensive Plan Land Use designation. The RSF District is the most appropriate zoning district to rezone this property since it is the primary zoning for single-family residential properties, is a standard zoning district and permits only single-family homes. While the R4 District permits single-family homes, it also permits twin homes which would be inconsistent with the surrounding development. The RLM District permits single-family homes, as well as Erhart Farm – 775 W. 96th Street July 20, 2021 Page 5 twin homes, townhouses and attached housing, but the RLM District also requires that large areas of upland are preserved or created as permanent open space to balance the higher hard surface coverage permitted on the individual lots. Finally, the PUD-R District can be created for a single-family subdivision, but the ordinance requires that the use of the PUD zoning also allows for a greater variety of uses, internal transfers of density, construction phasing and a potential for lower development costs. In exchange for this enhanced flexibility, the City has the expectation that the development plan will result in a significantly higher quality and more sensitive proposal than would have been the case with the use of other, more standard zoning districts. The proposed rezoning assists in the furtherance of the following land use goals of the City of Chanhassen Comprehensive Plan: Development will be encouraged within the MUSA line. The plan should seek to establish sufficient land to provide a full range of housing opportunities. o Development should be phased in accordance with the ability of the City to provide services. The proposed rezoning assists in the furtherance of the following housing goals of the City of Chanhassen Comprehensive Plan: A balanced housing supply with housing available for people of all income levels. A variety of housing types for people in all stages of the life-cycle. Staff is recommending the rezoning to RSF be approved. SUBDIVISION The applicant is proposing a 21 lot, seven outlot subdivision with dedication of public right-of- way. Except for Outlots A and B, which will be dedicated for permanent open space, the outlots will be developed in the future through another subdivision review process. Erhart Farm – 775 W. 96th Street July 20, 2021 Page 6 STREETS The proposed subdivision has access to public right-of-way via Eagle Ridge Road to the north and W. 96th Street to the south. The subdivision to the north, Foxwood, was required to construct Eagle Ridge Road as a minor collector, which terminated at a temporary cul-de-sac. The developer of the current subdivision, “Erhart Farms” must remove the temporary cul-de-sac and restore the area. The developer will be provided the $33,750.00 escrow which was collected from Foxwood for the removal of the temporary cul-de-sac along with other improvements at this location. Eagle Ridge Road will ultimately extend to Powers Boulevard as development continues to the west of the proposed subdivision. Eagle Ridge Road, a minor collector in the City’s roadway network is designed to provide a mixture of mobility and access, and serves a vital role by routing traffic from the local roads and funneling them to the arterial networks. The proposed subdivision, along with the future additions, are bound by Powers Boulevard to the west and Highway 101 to the east, which are both minor arterials and county roads. The proposed Erhart Farms subdivision has provided plans for the extension of Eagle Ridge Road along with providing access from the south via the extension of W. 96th Street, which gives secondary access to both the newly proposed development and the existing Foxwood development. The developer has provided a “ghost plat” of the future development, which conceptually takes into account the connection of Eagle Ridge Road to Powers Boulevard, highlighted in purple and seen below. The ghost plat adequately illustrates the nature of the minor collector by providing an equal mixture of mobility and access. Erhart Farm – 775 W. 96th Street July 20, 2021 Page 7 However, in order to limit the unintentional routing of traffic from Eagle Ridge Road, the minor collector, onto local roads, the proposed 4-way intersection must be redesigned so that the portion being designated as the minor collector does not require vehicles to stop. As currently proposed and after ultimate build-out, traffic heading southbound would have to come to a stop and then turn right to continue on the minor collector roadway, which may be confused with continuing straight which would route them to a local road. The developer and their design team have been working with staff to address this concern, and must continue to work with staff to update the public street layout to be resubmitted for review and approval prior to City Council considering final plat approval. A majority of the streets and their right-of-way are proposed to meet City Standards, however the small ring road abutting Outlot A, “Eagle Ridge Way”, is proposed to be a 26-foot wide back-of- curb to back-of-curb design within a standard 60-foot right-of-way. The variance from the City’s 31-foot wide street standard was requested by the developer in order to reduce impervious surface and save additional trees. As this will be a single-loaded road with homes on only one side of the road, staff finds that the variance regarding the street width is acceptable, with all other street section standards being adhered to. However, if the variance for the 26-foot street design is accepted, plans must incorporate sidewalks along “Eagle Ridge Way” to promote pedestrian safety along the narrower street section. A sidewalk must also be added along the W. 96th Street corridor extension, as when W. 96th Street is reconstructed sidewalk will be installed to promote pedestrian connectivity throughout the neighborhoods and to the surrounding the public trail network. A “5-foot pervious nature trail” is proposed that connects to “Road A” right-of-way and terminates at an existing stormwater facility that treats runoff from County Road 101. The connection point at “Road A” creates a mid-block crossing, i.e. there is no intersection at this Erhart Farm – 775 W. 96th Street July 20, 2021 Page 8 location. While the developer has not indicated whether the trail will be dedicated to the City or be owned and maintained by an HOA, mid-block crossings are not ideal locations for pedestrian crossings and should be avoided when able. The developer’s design team must address this concern. Lastly, the proposed street designs show areas that will be stubbed out for future road extensions when the property to the west develops. These stub outs need to be wholly incorporated in the right-of-way boundary on the plat. “Future Street Extension” signs attached to barricades must also be installed at these locations. DRAINAGE AND UTILITY EASEMENTS The preliminary plat provided illustrates mostly typical public drainage and utility easements DUE) along the proposed subdivision’s lot lines with a five-foot DUE along the side and rear lot lines and a 10-foot DUE along the front lot lines. Rear lot lines on Lots 1 through 15, Block 1 are atypical to accommodate proposed wetland buffers and conservation easements. DUE abutting the side lot lines of Lots 13 and 14, Block 1 are five feet wider than the typical 5-foot side lot DUE (a total of 20 feet wide between the two lots) in order to provide proper widths to maintain the storm sewer conveyance located between the lots. However, access to the large stormwater facility, which is partially located on Outlot B and partially located on Lots 14, 15, and 16, Block 1 needs to be addressed. Ideally, the stormwater facility would be wholly encompassed within an Outlot, along with the access route to the facility which is necessary to maintain the BMP. By including the access route within an Outlot, the route would be protected in perpetuity from encroachments and would require that the City maintain the area to ensure adequate ingress/egress. The developer and their design team must work with staff to improve the public stormwater facility’s access route. GRADING AND DRAINAGE Erhart Farm – 775 W. 96th Street July 20, 2021 Page 9 A portion of the property was issued Interim Use Permit (IUP) #2021-03 on December 4, 2020 by City Council for grading operations. This grading permit was requested for the dredging of Wetland 2, north of the subdivision. All terms and conditions of IUP #2021-03 shall remain in effect until the permit is terminated. While IUP #2021-03 did not directly impact any of the improvements associated with the Erhart Farms subdivision proposal, there are spoils from the wetland dredging that will be required to be removed entirely from areas where public improvements are proposed as wetland soils, or hydric soils, are typically high in organic materials and do not lend themselves to suitable engineering fill. A geotechnical report with soil borings conducted by Haugo Geotechnical Services, dated May 22, 2021 was provided by the developer. Grading plans must be updated to indicate the location of the borings as it appears there may be an error in the one of the measured surface elevations (SB-5) based on the provided map in the report. Groundwater was observed at boring SB-5 so the accuracy of the measured surface elevation must be verified. A geotechnical engineering firm shall be on-site during grading operations to ensure the City’s Standard Erhart Farm – 775 W. 96th Street July 20, 2021 Page 10 Specifications and Detail Plates are adhered to along with any Minnesota Building Code requirements. If groundwater is encountered during grading, the grades shall be adjusted to maintain a 3-foot separation from the bottom floor elevation and shall adhere to the recommendations of the soils engineer on site. Changes to grades shall be submitted to the City for review and approval. The developer is proposing to mass grade the site in order to construct the public streets, house pads and stormwater management areas. While grading plans are in general conformance with City Ordinances, there are multiple driveways that are proposed to be near the maximum 10% allowed by Ordinance. Plans will be required to show top of curb elevations at the centerline of each driveway to ensure that individual building permits for each lot are in conformance with the plans and do not require variances from the 10% maximum. Additionally, the developer’s engineer shall ensure that the maximum driveway grades shown on the plan are calculated such that a 10-foot landing is provided where the driveway connects to the street and a 5- to 10-foot landing is provided at the garage. The recommended grade at these locations is 3%. Lastly, grading is being proposed on Outlot E that will tie-in to Lots 1, 2, and 3, Block 2 and create a 3:1 slope for a maximum of 130 feet which will drain to these backyards. The developer needs to address this portion of the grading plan as to how the future addition on Outlot E will account for drainage. Portions of Lots 1, 2, and 3 may need further grading depending on the future build-out on Outlot E and should be taken into account during this phase of the development. Per Section 18-40(4)d.2.v. draintile services are required for Lots 1, 2, 3 and 4, Block 2 as these lots are proposed to drain from the back of the lot towards the street. RETAINING WALLS The developer is proposing one retaining wall within the subdivision which will be wholly located on Lot 8, Block 1. The wall is proposed to have a height of over four feet and must be privately owned and maintained. Walls over four feet in height shall be constructed in accordance with plans prepared by a registered engineer and shall be constructed of a durable material (smooth face concrete, masonry/mortared, railroad ties and timber are prohibited). EROSION PREVENTION AND SEDIMENT CONTROL The development will exceed one (1) acre of land disturbance and will, therefore, be subject to the General Permit Authorization to Discharge Stormwater Associated with Construction Activity Under the National Pollution Discharge Elimination/State Disposal System (NPDES Construction Permit). Additionally, an Erosion and Sediment Control Plan (ESCP) in accordance with ordinances shall be submitted for the grading operations of the subdivision. The developer has provided an ESCP along with a Stormwater Pollution Prevention Plan (SWPPP), and while overall the plan appears feasible, certain amendments will be required prior to acceptance of final plans. As such, the developer and their design team must work with staff to update the ESCP and resubmitted for review and approval with the submission of the final construction plans. Erhart Farm – 775 W. 96th Street July 20, 2021 Page 11 SANITARY SEWER AND WATER MAIN The subdivision has access to a 12-inch, C900 PVC trunk water main that was extended by the development to the north (Foxwood). This trunk main will eventually be looped to a 16-inch trunk main within Powers Boulevard when the property to the west develops. As such, the developer will be required to extend the 12-inch trunk water main and the City will reimburse the developer for the cost of oversizing this extension, as an 8-inch main would have been sufficient in supplying the subdivision’s water demand. The 12-inch trunk main will follow the street corridor to the south (“Road A”) as it will eventually connect to the future water tower location Location A”), as demarcated on plan sheet “Primary Through Road Connection Exhibit”. Water main stubs will be provided for future extensions when the property to the west develops, along with a stub leading to W. 96th Street. Any wells located on the property to be developed must be properly abandoned. A temporary lift station was installed by the Foxwood development to the north in order to provide sanitary service for that subdivision. It was anticipated that when future development to its south (i.e. the currently proposed development, Erhart Farms), the temporary lift station would be removed and that gravity sewer would be constructed to a planned permanent lift station on Powers Boulevard. The developer and their engineer have been working with staff since the pre-application meeting to determine the feasibility of abandoning the temporary lift station and constructing a new permanent lift station located near Outlot C abutting W. 96th Street, rather than constructing the gravity system to Powers Boulevard. Furthermore, this approach would eventually eliminate Lift Station 20 at the end of W. 96th Street, which when ultimate build-out is complete, would not increase the net number of lift stations that the City owns and maintains. After iterations of reviews and meeting with the applicant’s engineers, it has been determined that this approach is feasible. The lift station has been preliminarily designed to accommodate sewerage flows from Foxwood, the proposed Erhart Farms, portions of the future development to the west, and flows anticipated along W. 96th Street including the possibility of future development to the south. As such, any oversizing of the lift station and its components beyond what would be necessary to accommodate sewerage flows from Foxwood and the future development associated with Erhart Farms would be reimbursed by the City. Furthermore, the developer will be provided the $10,000.00 escrow that was obtained from the development to the north for the abandonment of the temporary lift station. The developer will be required to work with staff in the final construction plans and details of the proposed lift station along with its location. Additionally, as the proposed force main will be located on a large section of fill where the existing lift station is to be abandoned, a geotechnical engineer’s recommendation on proper back fill and compaction techniques must be provided. While generally the preliminary utility plans provided do appear feasible, profile views were not provided in order to conduct a complete review, e.g. checking for conflicts with other utilities or reviewing cover of mains to meet City Standards. The developer will be required to provide updated utility plans upon submittal of the final plat and final construction plans that include profile views. Additionally, sanitary sewer is being proposed at a pipe slope of 0.4%, the absolute minimum for 8-inch sanitary sewer mains in accordance with Recommended Standards Erhart Farm – 775 W. 96th Street July 20, 2021 Page 12 for Wastewater Facilities (2014 Edition). It is strongly recommended that plans be updated to incorporate a slope of 0.5% in order to allow for construction tolerances and promote constructability, as any sanitary sewer main installed with less than 0.4% slope will be required to be reconstructed to obtain the minimum slope. Lastly, prior to commencement of any utility work, a copy of all required permits from the appropriate regulatory agencies shall be provided to the City which shall include but is not limited to the Minnesota Department of Health, Metropolitan Council Environmental Services, and the Minnesota Pollution Control Agency. STORMWATER MANAGEMENT Article VII, Chapter 19 of City Code describes the required stormwater management development standards. Section 19-141 states that “these development standards shall be reflected in plans prepared by developers and/or project proposers in the design and layout of site plans, subdivisions and water management features.” These standards include water quality treatment resulting in the removal of 90% total suspended solids (TSS) and 60% total phosphorous (TP). The applicant will need to work with Riley Purgatory Bluff Creek Watershed District (RPBCWD) and the City in order to meet all the requirements. General 1. Applicant needs to provide a copy of an approved RPBCWD permit before work is started. Water Quality 1. Water quality levels appear to be met with the use of a baffle, sump, and filtration pond; 95% of TSS and 77% of TP is removed from the system, via MIDS modeling. a. Provide screenshots of BMP inputs to MIDS to confirm calculations. Volume Control 1. Infiltration was shown not feasible, due to soil type. Filtration is permitted as an alternate BMP. Filtration Basin Design 1. Provide an operation and maintenance plan that identifies the maintenance schedule and responsible party. This should include information on how the system will be cleaned out. 2. Provide baffle detail for CBMH 102. 3. The ‘Pond/Filtration Basin Section’ detail needs to be changed per the following comments: a. A geo-textile fabric should be installed between the natural soil and the filtration media. b. It is recommended that the draintile in both basins show a slope of at least 0.5% to prevent water from sitting in the draintile. Erhart Farm – 775 W. 96th Street July 20, 2021 Page 13 c. Provide the normal water level elevation for the wet pond section. d. Provide a detail for the Emergency Overflow Outlet shown on the north side of the pond/filtration basin. Civil Plans 1. Confirm if entrance from north will be used during construction. If so, a rock construction entrance should be shown. 2. On the Grading and Erosion Control plans the “Heavy Duty Silt Fence” detail should be replaced with a wire-backed silt fence. The wire backed heavy duty silt fence should be shown where grading extends to within 10 feet of wetland limits. 3. The project SWPPP and NPDES permit must be submitted to the City prior to the start of any earthwork. 4. The Joint Application for wetland impacts (or no loss) must be submitted to the City, and a Notice of Decision must be issued by the WCA LGU, prior to the start of any earthwork. STORMWATER UTILITY CONNECTION CHARGES Section 4-30 of City Code sets out the fees associated with Surface Water Management. A water quality and water quantity fee are collected with a subdivision. These fees are based on land use type and are intended to reflect the fact that the more intense the development type, the greater the degradation of surface water. This fee will be applied to the new lots of record being created. The fees will be assessed at the rate in effect at that time; 2021 rates are $8,660.00 per acre. ASSESSMENTS Water and sewer partial hookups are due at the time of final plat. The partial hookup fees will be assessed at the rate in effect at that time; 2021 rates for partial hookup fees are $691.00 per unit for sanitary sewer and $2,476.00 per unit for water. The remaining partial hookup fees are due with the building permit. Fees Based on the proposal, the following fees would be collected with the development contract: a) Administration fee: If the improvement costs are less than $500,000, 3% of the improvement costs. If the improvement costs are between $500,000 and $1,000,000, 2% of the improvement costs. If the improvement costs exceed $1,000,000, 2.5% of the first 1,000,000 plus 1.5% of the remainder. b) Surface Water Management fee: $8,660.00 per acre c) A portion of the water hook-up charge: $2,476.00/unit d) A portion of the sanitary sewer hook-up charge: $691.00/unit Erhart Farm – 775 W. 96th Street July 20, 2021 Page 14 e) Park Dedication fee: $5,800.00/unit f) Street lighting charge: $300.00/light g) GIS fees: $100 for the plat plus $30 per parcel h) Final plat process (review and recording of Plat and Development Contract): $450.00 WETLANDS AND BUFFERS Several wetlands were identified and delineated on and near the property. The applicant submitted a wetland delineation report in July 2020 and the wetland types and boundaries were approved in August 2020. A summary of the delineated wetlands and types can be seen in the table below. The applicant is showing impacting 100% of Wetland 1. The applicant must submit a Joint Application for wetland impacts for this proposed activity. In addition, a small area northeast of Lot 5, Bock 1 shows that the 5-foot pervious nature trail encroaching into Wetland 3. The applicant should clarify if this area would constitute as wetland impacts. If so, it would also need to be included in the Joint Application submittal. A Wetland Alteration Permit may be necessary if the proposed wetland impacts are not deemed exempt according to Sec. 20-417 of the City Code. The applicant has shown wetland buffers on the property. The applicant is showing to use buffer averaging to achieve the overall required buffer area. The wetland buffer widths and wetland buffer monuments appear to be sufficient. However, the plans show that grading is proposed within the wetland buffer in Lots 1 through 3, Block 1 and Lots 11 and 12, Block 2. The applicant should submit a landscape plan to ensure that this area sufficiently grows back with native buffer vegetation. LANDSCAPING AND TREE PRESERVATION Erhart Farm – 775 W. 96th Street July 20, 2021 Page 15 The applicant for the Erhart Farm, Phase I development submitted tree canopy coverage and preservation calculations. Total upland area (excluding wetlands, bluff) 17.62 acres Baseline canopy coverage 98% or 17.25 acres Minimum canopy coverage required 55% or 9.7 acres Proposed tree preservation 23% or 4.0 acres The developer does not meet minimum canopy coverage for the site; therefore the applicant must bring the canopy coverage on site up to the 55% minimum. The difference between the required coverage and the remaining coverage is multiplied by 1.2 for total area to be replaced. One tree is valued at 1,089 SF. Minimum required 9.7 acres Less canopy preserved 4.0 acres Minimum canopy coverage to be replaced: 5.7 acres Multiplied by 1.2 6.84 acres or 297,950 SF Divided by 1089 SF = Total number of trees to be planted 273 trees The applicant has submitted a landscape plan showing a total of 76 trees to be planted in the development. The applicant shall increase tree planting in the development to meet minimum requirements and submit a landscape plan showing 273 trees prior to final plat approval. Additionally, Northern Pin oak shall be replaced with white, bur, or red oak species. The alkaline soils of Chanhassen make the northern pin oak selection undesirable for long term survivability. Additional selections of tree species should expand the breadth of tree types and take into consideration the City’s requirement for species diversity. There are no bufferyard landscaping requirements for this development. Staff has reviewed the tree clearing limits for the development on the plans. There are a number of trees at the edge of the grading limits that staff would like to consider for preservation. Staff recommends that the developer conduct a walk-through of the grading limits on site prior to removals with City staff to inspect for opportunities for additional tree preservation. Staff supports the proposed conservation easements on Lots 4 through 9, Block 1. The existing woods in this area contain a diversity of native species such as sugar maples, red oaks, basswood and ironwood. Many of these trees are significant and provide aesthetic and environmental benefits within the community. A conservation easement would protect this area in perpetuity. The applicant is also proposing to preserve a very large oak on Lot 10. The bur oak is 46-inches in diameter and nearly 12 feet in circumference. This is a signature tree and could provide a signature landmark along Eagle Ridge Road. The protected area around the tree is tight. Staff recommends that the applicant explore options to eliminate grading within the dripline to improve chances of survivability. This is true of all trees proposed to be preserved in front and Erhart Farm – 775 W. 96th Street July 20, 2021 Page 16 side yards in Block 1. Ensuring the tree root zones are preserved to the greatest extent possible will assist greatly in the survivability of the trees. Failure to protect the root zones during construction will jeopardize all efforts invested in preservation. PARKS & RECREATION Park Plan The City’s comprehensive park plan calls for a neighborhood park to be located within one-half mile of every residence in the City. The park service area of community parks extends to a distance of 1-2 miles. The proposed Erhart Farm Subdivision is located directly adjacent to the 58-acre Fox Woods Park Preserve and directly across Highway 101 from the 45-acre Bandimere Community Park. Bandimere Community Park offers a wide and growing array of recreational amenities and has been open to the public since 1999. Development of public access points to the Fox Woods Park Preserve, through a combination of vehicle and pedestrian touch points as well as the installation of a series of nature trails within the preserve, will begin concurrent with the development of the Erhart property. Additional acquisition of public open space through the application of park dedication requirements is not recommended as a condition of the subdivision. Trail Plan Residents purchasing homes within the new Erhart Farm subdivision will have convenient pedestrian access to area public park facilities through careful planning and construction of some key pedestrian improvements: Planning and construction of interior sidewalks within the subdivision. Planning and construction of a Highway 101 trail connection between the current trail terminus at the Bandimere Park Pedestrian Underpass and the northern terminus of the plat adjacent to and along Highway 101. Planning and construction of interior trails within the subdivision from Eagle Ridge Road to Fox Woods Park Preserve and Powers Boulevard with future phases of the development. Park and Trail Conditions of Approval Full park fees in lieu of additional parkland dedication and/or trail construction shall be collected as a condition of approval for Erhart Farm for the 21 new housing units. The Park fees will be collected in full at the rate in force upon final plat submission and approval. Based upon the City’s 2021 single-family Park fee of $5,800 per unit, the total Park fees for Erhart Farm would be $121,800.00. Erhart Farm – 775 W. 96th Street July 20, 2021 Page 17 MISCELLANEOUS Building 1. A building permit must be obtained before beginning any construction. 2.

May not block emergency access or fire hydrants during construction at any time. Carver County Preliminary feedback on Erhart Farm Preliminary Plat PID# 251550022 1. Regarding access onto the County Highways a. A Transportation Impact Analysis (TIA) is required based on the number of proposed units for the full development of the parcel and potential traffic impacts to CSAH 101 and CSAH 17. The TIA will need to evaluate the operations at the following intersections: CSAH 17/Proposed local road intersection, CSAH 101/W. 96th St., and CSAH 101/Eagle Ridge Road intersections. See the attachment titled Appendix A: Traffic Impact Analysis Process for requirements. Based on TIA findings, County may impose reasonable conditions to mitigate development driven traffic impacts at these intersections. b. Future access is proposed at CSAH 17 for the full buildout of the development. The proposed access to CSAH 17 is located 0.15 miles from the CSAH 17/TH 212 ramp Erhart Farm – 775 W. 96th Street July 20, 2021 Page 18 intersection to the north and 0.29 miles from the CSAH 17/CSAH 14 intersection to the south. Turn lanes have already been constructed at the proposed access point. c. The County’s Access Spacing Map in the 2040 Comprehensive Plan (Figure 4.14) identifies this segment of CSAH 17 as Category 5B, which guides full access intersection spacing at 1/4 mile intervals and secondary (limited) intersection spacing at 1/8 mile intervals. As proposed, the distance to the CSAH 17/TH 212 ramp intersection meets the spacing guidance for secondary (limited) access consideration and the distance to the CSAH 17/CSAH 14 intersection meets the spacing guidance for full access consideration. More information and review of operations and safety analysis from the TIA is needed to determine the recommended and allowable intersection type at the CSAH 17 connection point. d. No additional direct access to CSAH 101 is proposed. Additional County review and approval will be required if this condition changes. 2. Regarding highway right -of-way a. CSAH 17 at this location is a 4-lane divided urban roadway facility with a trail on both sides. The existing right-of-way adjacent to the parcel varies but is approximately 50 feet from the centerline of the roadway plus a State-owned outlot with a variable width. The right -of-way and combined State-owned outlot for CSAH 17 appear to meet the right-of-way guidance for consistency with the County’s 2040 Comprehensive Plan (Figure B.6), but further review of preliminary plat and survey documents is required to confirm this. b. CSAH 101 at this location is a 4-lane divided urban roadway facility with a trail on both sides. The existing right-of-way adjacent to the parcel varies but is approximately 75 feet from the centerline of the roadway. The right-of-way for CSAH 101 appears to meet the right-of-way guidance for consistency with the County’s 2040 Comprehensive Plan (Figure B.6), but further review of preliminary plat and survey documents is required to confirm this. c. Review of plat documents is needed to ensure existing right-of-way around the two stormwater ponds adjacent to CSAH 101 is shown on the drawings. d. County recommends all new, dedicated outlots adjacent to the County right -of-way be owned by the City. 3. Noise mitigation along CSAH 17 and CSAH 101 is recommended via increased setback, berm, and/or other screening of planned dwellings adjacent to CSAH 17 or CSAH 101. 4. The County will need to review and approve the final grading plans for properties adjacent to CSAH 101 and CSAH 17. A grading permit will be required for grading work within the highway right-of-way. 5. The technical details of the final plat, its boundaries and form(s) will need to be reviewed and approved by the County surveyor. 6. Prior to any work affecting or on County highways or in County right-of-way, the applicant shall coordinate plans with the County Engineer and obtain a Utility or Excavating/Filling/Grading Permit(s) from Carver County Public Works: (www.co.carver.mn.us/departments/public-works/quick-links/permits). Final details of locations, grades, and profiles affecting County roads as well as any utility connections will need to be reviewed and approved prior to any permits. Erhart Farm – 775 W. 96th Street July 20, 2021 Page 19 7. Any damages, modifications, or changes incurred on County highways from current or approved conditions will need to remedied or updated at development expense, including costs incurred by the County. Planning When this parcel is platted, it shall be removed from the rural service district in the city of Chanhassen. Section 2-32 (c) Whenever any parcel of land included in the rural service district is platted, in whole or in part, or whenever application is made for a permit for the construction of commercial, industrial or urban residential building or improvement to be situated on such parcel or any part thereof, or whenever such building or improvement is commenced without a permit, the City Council shall make and enter an order by resolution transferring such platted or improved parcel from the rural service district to the urban service district.

Request lot frontage variance (All lots meet the lot width requirement at 30 feet setback.) Setbacks: 30-Foot Front and Rear; 10-Foot Side; Wetland 20-foot buffer 30-foot buffer setback VARIANCE The applicant is requesting the following variances as part of the subdivision: 1. Seven lots with less than 90 feet of frontage (Lots 3 through 9, Block 1). 2. One lot with a front yard setback variance of five feet to permit a 25-foot front yard setback (Lot 1, Block 1). 3. One lot with a 10-foot wetland buffer setback to permit a setback of 20 feet (Lot 1, Block) 4. Eagle Ridge Way is proposed to be a 26-foot wide back-of-curb to back-of-curb design within a standard 60-foot right-of-way. The variance is from the City’s 31-foot wide street standard. Erhart Farm – 775 W. 96th Street July 20, 2021 Page 21 Zoning variance findings section 20-58: Finding: A setback variance to permit the home on Lot 1 to remain in line with those of the existing development to the north is in harmony with the zoning standards. The lot frontages for Lots 3 through 9 are slightly below the 90-foot standard, but all lots meet the lot width at the building setback line. a. When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties" as used in connection with the granting of a variance, means that the property owner Erhart Farm – 775 W. 96th Street July 20, 2021 Page 22 proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding: The applicant’s proposed setback on Lot 1 is consistent with what is found on other properties in the neighborhood to the north and is predicated by the location of the existing road and wetland. The street frontages on Lots 3 through 9 are due to the tight radii on Eagle Ridge Way and the attempt to minimize the roadway width. b. That the purpose of the variation is not based upon economic considerations alone. Finding: The variance request is not solely based upon economic considerations, but to create a development in harmony with the environment. c. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The plight of the landowner is due to the existing development to the north of the parcel, the wetland located east of the proposed lots, and the design to preserve significant environmental features on the site. d. The variance, if granted, will not alter the essential character of the locality. Finding: The proposed subdivision will be compatible with the existing development to the north (Foxwood), will create single-family detached homes on lots exceeding those in that development, and be compliant with City Code. e. Variances shall be granted for earth-sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. Variance findings for subdivision (Street width): a. The hardship is not a mere inconvenience by providing reasonable access to Lots 2 through 10, Block 1 while reducing potential impacts to the natural features on the site; b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land including trees; a full sized public street is not necessary to provide access to these properties within the development; c. The condition or conditions upon which the request is based are unique and not generally applicable to other property because of the development design and wetland preservation; Erhart Farm – 775 W. 96th Street July 20, 2021 Page 23 d. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of subdivision regulations, the zoning ordinance and Comprehensive Plan since it will reduce potentially significant impacts on the site and within the neighborhood. RECOMMENDATION Staff recommends that the Planning Commission recommend approval of the rezoning of the development from Agricultural Estate District (A2) to Single-Family Residential District (RSF); preliminary plat with variances for street width, front yard setback (Lot 1, Block 1), wetland setback (Lot 1, Block 1) and street frontages (Lots 3 through 9, Block 1) subject to the following conditions: Building 1. A building permit must be obtained before beginning any construction. 2. Building plans must provide sufficient information to verify that proposed building meets all requirements of the Minnesota State Building Code, additional comments or requirements may be required after plan review 3. Retaining walls (if present) more than four feet high must be designed by a professional engineer and a building permit must be obtained prior to construction. 4. A final grading plan and soils report must be submitted to the Inspections Division before building permits will be issued. 5. Each lot must be provided with a separate sewer and water service. Fire 1. Confirming this will connect to Eagle Ridge Road to the north. 2. Fire hydrant locations and distancing look to be appropriate.

Request for Rezoning from Agricultural Estate District (A-2), to Single-Family Residential District (RSF), Subdivision Approval creating 21 lots and seven outlots with a Variance for a public street cross section, and Variances for lot frontages, front yard setback and wetland buffer setback. On July 20, 2021, the Chanhassen Planning Commission met at its regularly scheduled meeting to consider the application of Black Cherry Development, LLC 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 1. The property is currently zoned Agricultural Estate District (A-2). 2. The property is guided in the Land Use Plan for Residential – Low Density uses. 3. The legal description of the property is: See Exhibit A) 4. REZONING FINDINGS 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; 2 e. The proposed use can be accommodated with existing public services and will not overburden the City's service capacity; f. Traffic generation by the proposed use is within capabilities of streets serving the property. 5. SUBDIVISION FINDINGS a. The proposed subdivision is consistent with the zoning ordinance and meets all of the requirements of the “RSF” Single-Family Residential 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 stormwater 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 the subdivision ordinance; 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 stormwater 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. VARIANCE FINDINGS WITH A SUBDIVISION a. The hardship is not a mere inconvenience by providing reasonable access to Lots 2 through 10, Block 1 while reducing potential impacts to the natural features on the site and within existing off-site right-of-way; b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land including trees; a full sized public street is not necessary to provide access to these properties within the development, while preserving trees; 3 c. The condition or conditions upon which the request is based are unique and not generally applicable to other property because of the development design and wetland preservation; d. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of subdivision regulations, the zoning ordinance and Comprehensive Plan since it will reduce potentially significant impacts on the site and within the neighborhood. 7. VARIANCE FINDINGS – Section 20-58 of the City Code provides the following criteria for the granting of a variance: a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the Comprehensive Plan. Finding: A setback variance to permit the home on Lot 1 to remain in line with those of the existing development to the north is in harmony with the zoning standards. The lot frontages for Lots 3 through 9 are slightly below the 90-foot standard, but all lots meet the lot width at the building setback line. b. When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties" as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding: The applicant’s proposed setback on Lot 1 is consistent with what is found on other properties in the neighborhood to the north and is predicated by the location of the existing road and wetland. The street frontages on Lots 3 through 9 are due to the tight radii on Eagle Ridge Way and the attempt to minimize the roadway width. c. That the purpose of the variation is not based upon economic considerations alone. Finding: The variance request is not solely based upon economic considerations, but to create a development in harmony with the environment. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The plight of the landowner is due to the existing development to the north of the parcel, the wetland located east of the proposed lots, and the design to preserve significant environmental features on the site. e. The variance, if granted, will not alter the essential character of the locality. Finding: The proposed subdivision will be compatible with the existing development to the north (Foxwood), will create single-family detached homes on lots exceeding those in that development, and is compliant with City Code. 4 f. Variances shall be granted for earth-sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. 8. The planning report #2021-12 dated July 20, 2021, prepared by Robert Generous, et al, is incorporated herein. RECOMMENDATION The Planning Commission recommends that City Council approve the proposed rezoning from Agricultural Estate District (A-2), to Single-Family Residential District (RSF); Preliminary Plat approval for 21 lots and seven outlots; a Variance for public street cross-section; and Variances for lot frontages, front yard setback and wetland buffer setback for a single-family detached residential subdivision subject to the conditions of the staff report. ADOPTED by the Chanhassen Planning Commission this 20th day of July, 2021.

Abstract Property Address: 775 96th St. W, Chanhassen, MN. 55317 PID: 251550010 and 251550022 EXISTING SITE DESCRIPTION The development site includes 2 existing parcels totaling 117.14 acre in size. A single family residence with barn does exist on a 2.53 acre parcel internal to the property with the majority of the property currently undeveloped. The property is bound by Powers Boulevard to the west, TH 101 to the east, Fox Woods Preserve and Foxwood subdivision to the north and existing rural estate residential to the south. The site has rolling terrain with several wetland areas and wooded areas scattered on the property. The property does have right of way roadway access to Powers Boulevard, 96th Street and Eagle Ridge Road, there are also two platted right of way corridor stubs from Flintlock Trail and Homestead Lane (without constructed roads). The applicant has gathered wetland delineation information for the wetland areas adjacent to the proposed residential subdivision area, ponded water areas in future development area have also been surveyed. A portion of the parent property falls within the boundaries of the Bluff Creek Overlay District, however, no development is proposed near that area in this application. PRELIMINARY SUBDIVISION, REZONING AND VACATION REQUEST The proposed subdivision request includes creation of 21 new single family homes lots. The development proposal requires rezoning of only a portion of the existing Erhart property at this time. There will be a large remnant of land that will remained undeveloped and is assumed able to remain with current use and zoning. The proposed subdivision area will require rezoning of the property from A2 - Agricultural Estate District to RSF – Residential Single Family District. The proposed rezoning of the property from A2 to Preliminary Subdivision Submittal May 14, 2021 Erhart Farm – Chanhassen, MN Page 3 of 9 RSF will provide a per acre unit density (in developed area), consistent with the City’s Comprehensive Plan land use plan for the property. Comprehensive Plan Designation The parent property has two 2040 Comprehensive Plan Land Use designations within the full boundary. The property is primary guided as Residential Low Density with a section of land in the northwest corner along Powers Blvd and TH 212 guided as Office. The proposed residential subdivision area falls within the area guided for residential low density. Adjacent land uses to the south and north are either guided as Residential Low Density or Residential Large Lot and a section of land to the north is guided as Parks Open Space. All adjacent land uses are compatible to the proposed development proposal. The proposed subdivision consists of 21 new single family lots and 1 existing home to remain. Residential Low Density land use guides for single family housing density of 1.2 – 4.0 units per acre. The proposed development plan has a net density of 1.2 units per net acre within the proposed new lots subdivision area. Land Use Density Calculation Gross Acreage (Full Property) - [A] 117.14 acres Delineated Wetland Area (Wetlands 2, 3) 1 - [B] 22.564 acres Subdivision Related Outlots (A, B, C) 2 - [C] 27.045 acres Existing Residential Lot (Per proposed plat) -[D] 2.407 acres Future Development Outlots – [E] 74.547 acres Approximate Subdivision Net Acreage = A – B – D – E 17.622 acres Net Density (21 lots) 2 1.2 units per acre Notes: 1) Wetland 1 is excluded as the development plan proposes to impact this wetland and Wetland 4 is excluded since it is in a future development area. 2) Calculation includes Outlots A, B and C for density estimate (with wetlands 2 &3 areas deducted) Zoning Classification and Rezoning Request The proposed application requests approval for rezoning a portion of the property proposed as new single family homes from Agricultural Estate District (A2) to Residential Single Family District (RSF). The proposed rezoning is consistent with the guiding land use for the property and consistent with adjacent uses. The Foxwood development to the north of was zoned Residential Low and Medium Density District RLM) and the properties to the south are Agricultural Estate District (A2). The development site land not subdivided as new single family lots can remain as currently zoned, Agricultural Estate District (A2). There are a few lots that do not meet all the criteria of the RSF District standards and thus this application does request review and approval of 3 variance requests. See Variance Request section in this narrative for detailed request. A summary of required and proposed lot standards criteria for RSF zoning is as follows: Required Proposed Lot Area - Minimum 15,000 SF 15,029 SF (0.345 ac) Average Lot Area N/A 20,844 SF (0.479 ac) Preliminary Subdivision Submittal May 14, 2021 Erhart Farm – Chanhassen, MN Page 4 of 9 Lot Width – Minimum R/W Frontage 90’ 63.42’ (Variance Requested) 1 Lot Width – Minimum @ Front Setback N/A 90’ 2 Lot Depth – Minimum 125’ 134.4’ Setbacks: Front 30’ 30’ (25’ min) (Variance Requested)3 Rear – Principal 30’ 30’ Side – Structure 10’ 10’ Wetland Buffer 30’ 30’ (20’min) (Variance Requested) 4 Maximum Impervious Lot Coverage 25% 25% Maximum Principal Structure Height 35’ 35’ Minimum Right-of-Way Width 60’ 60’ Notes and zoning exceptions requested, also see Variance Request section of narrative: 1) Variance requested for reduced frontage width for 7 lots (Lots 3-9, Block 1). 2) Proposed minimum lot width measured at the front setback. 3) Variance requested for 1 lot (Lot 1, Block 1) to reduce front setback to 25’ (only lot directly adjacent to Foxwood lots). 4) Variance requested for 1 lot (Lot 1, Block 1) to reduce wetland buffer setback to 20’ (lot adjacent to Foxwood lots). Subdivision Features and Benefits 21 new single family homes and inclusion of the existing home to remain Preservation of onsite wetlands and creation of wetland buffers. Outlots provided over the preserved wetland area abutting the proposed new single family lots. Wetland outlot B to be provided to the City after final platting. Wetland buffer creation in accordance with City and Watershed requirements. Extension of public watermain south to 96th Street. Removal of the “temporary” Foxwood lift station and proposal for a new permanent lift station that can be designed to accommodate future service for the existing homes on 96th Street. Significant tree preservation in area of development including proposal for a conservation easement area. Site plan provides a secondary right of way connection for the existing Foxwood and 96th St. housing developments. Extension of public right of way including roadway, sanitary sewer, and watermain to the southern property boundary. Installation of stormwater management facilities to provide volume control, water quality and rate control for runoff from the new roadway surfaces prior to discharging to the existing wetlands. Site Access and Pedestrian Circulation The initial phase of the development site has available vehicular right of way access from Eagle Ridge Road by way of the Foxwood Development and 96th Street. Both Eagle Ridge Road and 96th Street currently dead-end with temporary style turn-arounds. The development as proposed will provide second access points to 2 existing developments improving the emergency servicing ability for each development as well as the proposed Erhart Farm project. Preliminary Subdivision Submittal May 14, 2021 Erhart Farm – Chanhassen, MN Page 5 of 9 The Eagle Ridge Road and 96th Street roadway extensions are proposed with the City standard 60’ wide right of way and a 31’ back of curb to back of curb road width. A public sidewalk is proposed along Eagle Ridge Road from Foxwood southerly to the proposed intersection with 96th St and along 96th St. The proposed Eagle Ridge Way roadway section is proposed with a modification to City standard. The development plan proposes the typical 60’ right of way width for Eagle Ridge Way, however, the road width is proposed at a narrower 26’ back-to-back width. The proposed narrower width is requested to reduce impervious surface, save additional trees and because this will be a single loaded road with homes only on 1 side of the street. The project is also proposing a nature trail routed along the rear of several lots adjacent to wetland 3 that will be placed within a trail easement. The plan is for this trail is to ultimately cross the wetland 2 overflow outlet to wetland 3 and connect to the TH 101 trail. Grading and Topography The site has been designed to fit within the existing natural features and topography. Mass grading will be required to construct the public roadways, house pads, and stormwater management areas. Some small retaining walls will be necessary to construct some future home sites, however, they are designed to stay within individual lots with no cross-lot walls needed and thus will be the responsibility of the future lot owners. Since the retaining walls are contained within individual lots they will be built as needed with the home construction and could vary from depiction is subdivision submittal plans. The mass grading activities do require removal of several onsite trees, however, there are significant tree savings proposed. The grading plan proposed little to no grading within proposed wetland buffers and existing steeper slope areas. Per City requirement all proposed graded slopes will not exceed 3 horizontal to 1 vertical. Sanitary Sewer and Watermain The site has limited access to public sanitary sewer via an existing lift station within Foxwood, however, City Staff has provided direction that no additional homes should be added to the existing Foxwood lift station. The Foxwood lift station was designed as “temporary” when the Foxwood project was constructed and the long term plan was to connect the Foxwood gravity sewer to another lift station in the future. The Erhart Farm development proposes to construct a new permanent lift station in the south end of the proposed plat near 96th Street. The new lift station would allow for the removal of the Foxwood lift station, however, the existing forcemain within Foxwood would be used by the new lift station. The proposed lift station will also be designed with depth to serve the homes along 96th Street and that will allow for the City to remove the existing lift station servicing the 96th St homes in the future. The existing 4” forcemain that outlets the Foxwood lift station will be the same outlet for the proposed lift station. The 4” forcemain does have a capacity for up to 180 homes, assuming the construction of a new lift station, wet well and pumps to accommodate the additional flow. The existing Foxwood lift station current serves 48 homes and the current development proposal will add 21 new homes (the existing home is not included at this time). This will leave additional service capacity for roughly 111 homes with construction of the new lift station. The site will connect to public water via a 12” public watermain at the south end of Foxwood within Eagle Ridge Road. The 12” watermain will be extended southerly through the project within Eagle Ridge Road and stub for future extension. The project will extend or stub 8” diameter lateral trunk watermains within the development and easterly in 96th Street for future connection to the homes in 96th St. Preliminary Subdivision Submittal May 14, 2021 Erhart Farm – Chanhassen, MN Page 6 of 9 Stormwater Management The development is located within the Riley Purgatory Bluff Creek Watershed District and so is required to provide stormwater management in accordnance with RPBCWD and City regulations. The proposed development’s stormwater management plan does provide the required volume control, water quality, and peak rate control. The development will provide stormwater management via one treatment basin. The development is also proposing some permanent preservation of upland area within conservation easement. Runoff to infiltration areas from the proposed roadways will be captured and pretreated in a sump manholes and forebays prior to discharging into the basins. The basin will provide the required water quality and rate control of stormwater prior to discharging to the downstream wetland. Wetland Management The site’s wetlands were delineated by Kjolhaug Environmental Services (KES). KES delineated any wetlands near the proposed single family subdivision area and 4 wetlands (1, 2, 3 and 4) were identified. A MnRAM analysis has been performed with the delineation to confirm the classifications of the wetlands. The City of Chanhassen and Riley Purgatory Bluff Creek Watershed District have slight differences in wetland classification labels and regarding wetland buffers requirements. The following is a summary of the buffer requirements for the project: Local Governmental Unit City of Chanhassen Riley Purgatory Bluff Creek Watershed District Wetland Classification Buffer Strip Requirement Principal Structure Setback to Buffer Accessory Structure Setback to Buffer Wetland Classification Average Buffer Width Required Min.

This combination of buffer and buffer setback that slightly exceeds the City’s standalone requirement. The project does request variance to reduce the principal structure setback to buffer for one lot (Lot 1, Block 1), see Variance Request section of narrative. The following is a summary of the proposed wetland buffers: Wetland Area4 Classification Lineal Frontage3 Buffer Area For Avg Calc.4 Minimum Buffer Width Average Buffer Provided 11 2,238 SF MANAGE 1 2 139,758 SF MANAGE 1 986 LF 42,497 SF 20’ 43.1’ 3 843,116 SF MANAGE 2 1,871 LF 75,742 SF 20’ 40.5’ 42 19,962 SF MANAGE 2 Preliminary Subdivision Submittal May 14, 2021 Erhart Farm – Chanhassen, MN Page 7 of 9 Notes: 1) This wetland is assumed to be fully impacted by development and will require mitigation permitting. 2) A buffer to wetland 4 is not proposed at this time as there is no development proposed abutting that wetland. 3) Lineal frontage listed is as assumed for buffer requirement calculation, also refer to wetland management plan for additional calculation details. 4) Actual wetland buffer to be provided is greater than value used for averaging calculation. The development plan proposes impact to 1 of the delineated onsite wetlands. The small wetland 1 is to be impacted because of the necessary road construction and associated grading and changes to existing hydrology. It is assumed that the necessary wetland mitigation will be done offsite through purchasing wetland banking credits. The applicant has previously received an interm use permit (IUP) to excavate within wetland 2 delineated limits to create water storage areas. The wetland 2 work started in winter 2021 but was not able to be finished at that time, and that work is proposed for completion in Winter 2021/22. The applicant has also received no loss permit approval to excavate with a portion of Wetland 3 and plans to complete that excavation work in winter 2021/22 as well. Tree Preservation The estimated baseline tree canopy coverage for the full development site is 60% of the net area (excluding wetland areas). Per the City code, low density residential is allowed to remove trees to a limit of 35% tree canopy prior to requirement of replacement mitigation. The development plan proposes to maintain tree canopy coverage of 47% for the property and thus no tree preservation plan specific tree replacement is required at this time. The applicant is proposing a conservation easement over a portion of the rear of lots along Eagle Ridge Way and abutting the buffer area of wetlands 2 and 3. Landscaping The landscape plan for the project includes boulevard trees and seeding of disturbed areas and stormwater management area. The proposed single family yards will be vegetated with typical residential turf grass, disturbed outlot areas with native seed mix, and pond and infiltration basin with appropriate seed mixes. EASEMENT VACATION REQUEST The proposed subdivision plan does require a lot line adjustment to the existing residential lot that currently contains 1 home and barn. The home and barn will remain at this time and the dimensions of the lot containing the existing home will be slightly modified. As a result of needing a modification to the existing lot, the applicant is request approval to vacate the standard public drainage and utility easements within the existing lot. The proposed preliminary plat does propose to replace public drainage and utility within the newly configured lot. It is understood that the vacation will not officially be enacted until the property is final platted and the proposed easements can be established. Preliminary Subdivision Submittal May 14, 2021 Erhart Farm – Chanhassen, MN Page 8 of 9 VARIANCE REQUEST The subdivision as proposed request review and approval of 3 variances including: 1. 7 RSF zoned lots (Lots 3-9, Block 1) with less than 90 lineal feet of right of way frontage. 2. 1 RSF zoned lot (Lot 1, Block 1) with a proposed front setback of 25’ 3. 1 RSF zoned lot (Lot 1, Block 1) with a proposed wetland buffer setback of 20’. Variance Explanation and Justification 1. Variance is requested for 7 lots (Lots 3-9, Block 1) to reduce RSF zoning required minimum lot frontage from 90 feet to dimensions as proposed per preliminary plat. All 7 lots are along the internal single loaded loop road called Eagle Ridge Way. The variance request is needed due to the lineal footage hardship created by ‘tighter’ horizontal roadway curves limiting right of way frontage. The applicant is proposing a narrower road pavement surface and tighter alignment to minimize the roadway ‘footprint’ and maximize preservation of trees, yet still create enough lots to meet the City’s density goals for the area. All 7 lots do meet the typical RSF required lot width at the front setback and exceed the minimum lot area and depths. There are ways to create irregular dimensioned right of way to get to a lot frontage calculation equal to 90’ per lot, however, the applicant prefers to request approval of a variance in this case as the preferred design. Variance approval would result in lots with: a. Smallest lot area (Lot 3, Block 1) of 18,046 sf and the average lot size for the 7 lots of 24,628 sf or 64% greater than the RSF minimum of 15,000 SF. b. 90’ minimum lot width provided at 30’ front setback for all 7 lots. c. A minimum lot depth of 174’ for the 7 lots and most are well over that depth. d. Proposed conservation easement on the sloped tree area within a rear portion of most of these lots. 2. Variance is requested for a reduced front yard setback for Lot 1, Block 1 from the typical RSF zoning 30’ front yard setback to the typical RLM zoning 25’ front yard setback. This lot is the only Erhart Farm lot proposed directly adjacent to homes within the Foxwood development. The Foxwood project was developed with RLM zoning standards including a 25’ front yard setback. Proposed variance would allow for Lot 1, Block 1 to have same front yard setback as the existing lot located directly north of the proposed lot. Variance request to reduce the front setback is due to the shallow lot hardship directly created for the lot by the location of the existing Eagle Ridge Road right of way (constructed with the Foxwood development) and the proximity to wetland 2. 3. Variance is requested for a reduced principal structure setback to a wetland buffer for Lot 1, Block 1 from the typical 30’ wetland buffer to a 20’ principal structure setback. The variance request to reduce the setback is due to the shallow lot hardship directly created for the lot by the location of the existing Eagle Ridge Road right of way (constructed with the Foxwood development) and the proximity to wetland 2. Wetland 2 has a manage 2 classification with a 20’ minimum buffer required and an allowed 15’ accessory structure setback to the buffer. The reduction of the principal structure setback from 30’ to 20’ will better allow for home construction on the lot. Variance request to reduce the setback is due to shallow lot hardship directly created for lot by the location of the existing Eagle Ridge Road right of way which was constructed with the Foxwood development and the proximity to wetland 2. Variance approval of requests 2 and 3 would result in a developable lot (Lot 1, Block 1) with: a. Lot area = 15,333 sf Preliminary Subdivision Submittal May 14, 2021 Erhart Farm – Chanhassen, MN Page 9 of 9 b. Lot width (R/W frontage) = 114.94 ft c. Min lot depth = 134.4 ft d. Buildable principal structure pad depth = 55 ft TIMING/PHASING If the City approves the preliminary subdivision and rezoning request, it is the Applicant’s desire to proceed immediately with application for final plat review and plans for a mass grading start in Late Summer/Fall 2021. CONCLUSION The applicant respectfully concludes that the request for a rezoning and preliminary subdivision approval will allow for a development consistent with City Goals and Objectives for this area. The proposed development will create a single family subdivision that; meets density goals of the area, is consistent with the adjacent land uses and upgrades and extends public utilities and right of way to adjacent properties.

Introduction The purpose of this process is to provide guidance to applicants assessing the potential transportation impacts of a new development or a redevelopment.The following guidelines have been developed to provide a clear,orderly,and consistent analysis by establishing minimum standards for all Traffic Impact Analysis TIA).County staff will review the TIAs based on these criteria. II. Transportation Impact Analysis TIA) A TIA is a study which assesses the effects that a particular development will have on the transportation network in the community.These studies vary in their range of detail and complexity depending on the type,size and location of the development.TIAs should accompany developments which have the potential to impact the transportation network.It will be determined in the early review meeting if a TIA is necessary.These studies can be used to help evaluate whether the development is appropriate for a site and what type of transportation improvements may be necessary.For the purposes of the TIA,all land at one location,including existing developments or available land for building development under common ownership or control by an applicant shall be considered when determining if required criteria are met.An application shall not avoid the intent of this criterion by submitting a partial or segmented application or approval request for building permits,development plans,subdivision,etc. III. Transportation Impact Analysis Triggers a) A TIA is required for any development meeting any of the following criteria: i) generating approximately 750 or more vehicle trips per day. ii) generating approximately 100 or more vehicle trips in any one hour period. iii) if associated roadway traffic is increased by 50%or more. iv) development will likely create a hazard to public safety. v) development traffic will substantially affect an intersection or roadway segment already identified as operating at an unacceptable level of service as determined by the County. The trip rates in the most current edition of the Institute of Transportation Engineers ITE)Trip Generation should be used in determining the amount of traffic a particular development will generate. If the proposed use is an expansion of an existing facility then existing traffic patterns should be extrapolated to the proposed improvement.If no ITE rates exist for a particular type of development or there is some uncertainty regarding the need to conduct a study,the County Traffic Engineer will determine if a TIA is required.If an applicant believes a TIA is not necessary then a written justification will be required.County staff will review the document and determine how to proceed. b) A TIA is not required when a development falls below the above mentioned threshold. A traffic study may be required in lieu of a TIA. Carver County will consider the following effects in the evaluation of traffic studies that are warranted by certain zoning,land use,conditional use permits and final development plan applications prior to the application being submitted: i) Does the development significantly affect the operation and congestion of the adjacent roadways or intersections and/or result in a traffic hazard? ii) Does the development significantly affect pedestrian safety? iii) Does the development provide feasible opportunities to address an existing traffic issue or safety problem? c) Sound engineering practices and applicable regulatory standards shall be used to evaluate any development proposal,regardless of the development size or scope. d) Developments adjacent to another jurisdictional entity shall submit the traffic study to the respective agency for their information. IV. Transportation Impact Analysis Study Area a) The transportation consultant and project manager shall meet with the County Traffic Engineer to establish the study area,to discuss critical issues,and to determine the complexity of the report to be submitted.A preliminary site plan showing the planned development,internal circulation,and connection to the public roadway system shall be provided to the County at the initial meeting.The study area shall be approved by County staff. b) All site access drives,adjacent roadways,and adjacent major intersections,plus the first affected signalized intersection in each direction from the site shall be analyzed.Additional areas may be added based on development size and specific site or local issues and policies.A general guideline for setting the project study boundary will be when a development’s traffic using any particular intersection falls below 20%. V. Transportation Impact Analysis Requirements A TIA shall be completed by a qualified Professional Engineer P.E.).All traffic analysis shall utilize software consistent with MnDOT practice such as the latest versions of Synchro/SimTraffic and for roundabouts SIDRA or ARCADY.The TIA report will usually include the following: a) Report Letter i) Identify the person(s)to whom the report is addressed. ii) Summarize the findings and recommendations. iii) Clearly define peak traffic periods. b) Proposed Development and Study Area. i) Describe proposed development. ii) Map of site and street network. iii) Identify intersections/highway links to be analyzed. c) Existing Traffic Conditions i) Figures showing ADTs,peak hour turning movements and levels of service for all applicable peak hour and peak hour of development unless otherwise directed by the County Traffic Engineer). ii) Indicate roadway/intersection geometrics,street right of way,type of traffic control at intersections,traffic regulations i.e.no parking zones,posted speed limit),and bus stops. iii) Determine queue lengths at controlled intersections that may affect project. d) Future Projected Traffic Conditions Without Development Utilize County Travel Demand Model or historical growth information) i) Figures showing future projected ADTs,peak hour turning movements and level of service. ii) Identify changes in road network and land use expected under full development conditions. iii) Determine queue lengths at controlled intersections that may affect project. e) Existing Site Traffic i) Site generated traffic ADT and peak hours. ii) Figure showing distribution by direction of approach. iii) Figure showing assignment volumes and turning movements)to each link in the network analyzed. f) Proposed Site Traffic i) Site generated traffic ADT and peak hours if development is to be completed in phases,show cumulative traffic for each phase added) ii) Figure showing distribution by direction of approach. iii) Figure showing assignment volumes and turning movements)to each link in the network analyzed. iv) "Pass by"trip assumptions,distribution and assignment. g) Traffic Impact of Proposed Development i) Figures showing ADTs,peak hour turning movements and level of service for present conditions with proposed development. ii) Figures showing ADTs,peak hour turning movements and level of service for future projected conditions with proposed development. iii) Determine queue lengths at controlled intersections that may affect the project. iv) Review ingress/egress sight distance,capacity and safety. v) Review on site circulation for vehicles and pedestrians. h) Problem Areas i) Identify congestion or safety problems for present conditions with proposed development. ii) Identify congestion or safety problems under full development conditions with proposed development. iii) Identify crash experience and expectancy. i) Travel Demand Management Plan i) A travel demand management plan shall be included as part of the analysis ii) Bicycle and Pedestrian Facilities provide for access to,from and through development for bicyclists and pedestrians;recommend designated bicycle paths,lanes and facilities) j) Recommended Improvements and Mitigation Measures i) Identify possible short term improvements and mitigation measures. ii) Identify possible long term improvements and mitigation measures iii) Recommended improvements and mitigation measures k) Appendices i) Capacity analysis calculations,data and assumptions provide sufficient information for reviewer to follow analysis and to be able to spot check results). ii) Queue length analysis calculations,data and assumptions. iii) Provide other pertinent information that may be needed to explain or justify data used in the report i.e.,if data from an actual field study of sites in the metro area is used in place of ITE trip generation rates,then a report of the field study results should be included in the appendix) The TIA must be submitted at the same time as the appropriate development application to the City. However,the developer may find it advantageous to have the TIA completed and submitted to the County several weeks prior to the submittal of the development application in order to incorporate recommendations from the traffic report on the development plan.The completed TIA meeting the above requirements will be reviewed by County staff and written comments will be provided within 30 days.

PUBLIC PRESENT: Robert Boecker 610 W. 96th Street Gary & Lane Burdick 731 W. 96th Street Dr. Carissa Haverly 750 W. 96th Street Roger & Kim Lee 600 W. 96th Street Elaine & Johnnie Meyering 1050 Homestead Lane Andrew Riegert 620 W. 96th Street Martin Schutrop, Schutrop Building & Dev. Corp. 540 Lakota Lane, Chaska Chairman von Oven reviewed guidelines for conducting the Planning Commission meeting. Vice Chair von Oven stated both Public Hearings will go before the City Council on Monday, August 9, 2021. PUBLIC HEARING: CONSIDER A REQUEST TO REZONE PROPERTY FROM AGRICULTURAL ESTATE DISTRICT (A2) TO SINGLE-FAMILY RESIDENTIAL (RSF) AND SUBDIVISION OF PROPERTY INTO 21 SINGLE-FAMILY LOTS WITH VARIANCES AT 775 96TH STREET W. Senior Planner Generous presented the staff report on this item, noting the applicant is requesting the rezoning of the property, which would be consistent with the Comprehensive Plan and subdivision approval to create 21 single-family lots and several outlots with dedication of public right-of-way. The property is zoned Agricultural Estate District (A2) which is really a holding district in the community and is guided for residential low-density uses which permits densities of 1.2 to 4 units/acre. The proposed density of the part they are platting with the first phase would be 1.69 units/acre and is within the density range permitted by the Comprehensive Plan. There is a large wetland complex on the eastern portion of the property and a portion of the site is heavily wooded; the applicant has allowed the neighbors to use the wooded area as a walking area and permitted horse trails. Mr. Generous noted the RSF district is consistent with the Planning Commission Minutes – July 20, 2021 2 Comprehensive Plan and looked at other districts but none were really appropriate. Staff is in support of rezoning to RSF which is consistent with the land use and is also one of the most common for single-family homes in Chanhassen. The subdivision would create 21 single-family homes on the eastern part of the subdivision and replat the farm site; access would be via public streets from Eagle Ridge Road to the north and 96th Street to the south. City sewer and water would be extended into the project and would move the current lift station on the north side of the project to the very south side of the project and it will be sized sufficiently to handle additional sanitary sewer. As part of the development, the applicant is also providing stormwater treatment. As part of the first phase of development, there is not a lot of tree preservation as there is a huge knoll (shown onscreen) and to bring it down and make it suitable for development they will have to do quite a bit of grading so that entire area will be disturbed. Mr. Generous also noted another area to be disturbed to provide stormwater ponding. There is a significant amount of tree replacement that needs to be done and current analysis says that is 273 trees. Project Engineer, Erik Henricksen, presented and noted staff conducted a review of the grading and drainage plan and found that it is in general conformance with ordinances and standards. There are a few areas that would be “Do Not Disturb” areas, one being on Outlot A, a small portion on Lot 10, Block 1, to save an old, very significant oak tree, and some other preserved areas. Grading is proposed on Outlot E and the City is working with the developer’s engineers to see an exhibit of the ultimate build-out and grading plan for the area to be sure there is no adverse drainage impacts to the lots located on Block 2. Earlier this year, the property was issued grading Interim Use Permit #2021-03 for the dredging of a wetland north of the proposed development and the applicant is about midway through completion and there is a stockpile of wetland spoils which are not conducive to engineering fill or house pad support and they will want to ensure that is relocated or removed. Mr. Henricksen walked the Commissioners through public sanitary and water mains including 8” sanitary sewer, 12” trunk main, and relocation of an existing temporary lift station. Lift Station #20 at the end of W. 96th Street would be removed and all of the sanitary sewer after W. 96th Street is reconstructed would be accommodated with the oversizing of the new lift station. The applicant has provided preliminary designs for that lift station and it does prove feasible. The City is still working through plans to get a final location for the lift station. Finally, the oversizing of all of the public utilities required would be reimbursed by the City, including the 12” PVC trunk main and the lift station. Mr. Henricksen walked the Commissioners through public storm sewer and said the applicant’s approach to stormwater management is feasible through the use of a baffle, catch basin sumps, and filtration pond. Staff is working with the applicant to find a more ideal access to this public facility as right now it is located in backyards which can sometimes prove difficult to get access to for maintenance dredging. Street connectivity goes from the termination of Eagle Ridge Road with W. 96th Street which was a requirement from Public Works and Fire for emergency vehicle access. The applicant is asking for a variance from the typical street width which is proposed to be 26 feet wide rather than 31 feet wide because it is single loaded with houses on one side and to save additional trees. Staff recommends approval of that with the condition of a sidewalk installed on that portion. A nature trail is proposed with a mid-block crossing and staff is working with the developer to find a different location. Mr. Henricksen walked the Commissioners through potential street collector roads and design alternatives to improve the traffic flow. An ideal water tower location was noted on screen and spoke about as a W. 96th Street improvement tentatively scheduled for 2026. Planning Commission Minutes – July 20, 2021 3 Mr. Generous said there are four variance requests, of which three are from the Zoning ordinance. First, seven lots have less than 90 feet of frontage, however when they go back to the building point they all meet or exceed the 90 foot requirement so staff is in support of that. Second, they are requesting setback variances for Lot 1 which is the most northerly lot and is directly next to the Foxwood development and the front setback would match the smaller setbacks of that development; because it is between the roadway and the wetland they are also requesting a variance from the wetland setback on the back. Eagle Ridge Way is proposed to be a 26-foot wide road and staff is in support of all the variance requests with this development. Staff believes the applicant will be able to preserve wetlands in their current conditions. Staff is recommending approval of the rezoning, approval of the Preliminary Plat with variances for the street width and front yard setback, wetland setback, and street frontages subject to the conditions in the staff report, and adoption of the Findings of Fact and Recommendation. Commissioner Reeder asked the City’s frontage requirement. Mr. Generous replied it is 90 feet. Commissioner Reeder asked how small the lots are that are being asked for variances. Mr. Generous replied the smallest width was approximately 87 feet. He reiterated once they get to the 30-foot setback they meet or exceed the 90 feet of width. Vice Chairman von Oven asked on the proposed width of the street that needs the variance, are there any concerns with fire trucks or ambulances getting through that area? Mr. Henricksen noted there are no concerns from the Fire Department, and Fire Code does state the minimum width for private streets is about 20 feet. There are certain requirements that must be met, Fire performed a review, and there were no flags raised. Public Works and Engineering does not have a concern other than keeping pedestrians on a sidewalk and out of the street. Mr. Generous stated one side of the street will be signed as “no parking.” Vice Chairman von Oven asked to see the slide with concerns about water. He asked if staff could predict what the applicant will come back with for drainage and where the water will go. Mr. Henricksen noted the applicant provided sheets that show the detail of the high point in the back and demonstrated some routes on screen and stated they do want to ensure feasibility and ensure everything has been checked so there are no impacts to the existing lots. Vice Chairman von Oven asked, regarding the oversizing of the lift station, will that choice have any negative impacts on the residents of W. 96th Street, whether it is a temporary shutdown or changeover? Mr. Henricksen stated sewer and water should and will always be provided during construction and reconstruction of the W. 96th Street corridor. The oversizing of the lift station will be Planning Commission Minutes – July 20, 2021 4 oversized and built to accommodate when that construction occurs. He explained more about gravity, current lots, and future lots and the future lift station. Commissioner Reeder asked if there was a tree survey done and if he can see where the trees are currently and where they will be taken down. Mr. Generous explained the trees are all throughout the area. Mr. Henricksen showed a satellite view and explained tree coverage. Commissioner Reeder asked if there will be any trees left in the area they are currently developing. Mr. Generous replied, yes, and pointed out the areas on screen, including a large oak that they want to preserve. Commissioner Alto noted it was mentioned that the rezoning fits into the 2040 Comprehensive Plan and asked how many other areas there are in Chanhassen that could be up for development for that plan. Mr. Generous stated Residential Low Density (RLM) is the largest land use; west of Highway 101 is guided for RLM as well so once sewer and water becomes available they could redevelop. Commissioner Alto said it looks like the W. 96th Street neighborhood is older than Eagle Ridge. She asked if the developer knew the price point of the proposed development versus the price point of the houses below and above. Mr. Generous believes the same developer that did Foxwood is interested in this and the applicant could speak about that. A representative from Black Cherry Development, Tim Erhart, approached the podium and said he and his wife bought the property when they moved to Chanhassen in 1980 and moved onto the old farm site and rebuilt the house. He got into the hobby of growing, cultivating, and straightening trees, and building trails; they also built or restored seven ponds on the property and it has been a beautiful and fun nature project. He wants to see it properly incorporated into the enclave of south Chanhassen with trails and further pond development. He shared the history of how the project came to be and noted two years ago he had no notion of selling any of the land and a friend from Gonyea stated they had excess sewer capacity on the temporary lift station and were out of lots so asked if he would be willing to sell some land. He feels very comfortable about the project as it is today. He pointed out the last wetland that he wanted to restore is about halfway done. He noted, regarding trees, it was submitted that they would clear out all of the trees for the houses and that is not the case. Now that tree preserve will allow individual lot owners to optimize their lot, he believes that will lead to a lot less tree removal than shown on the plan. He loves trees and is working very hard to make it good. Regarding the prices of the homes, he believes other homes in Foxwood are going for $800,000-$950,000 although it is a tough question. Planning Commission Minutes – July 20, 2021 5 Vice Chairman von Oven opened the public hearing. Dr. Carissa Haverly, 750 W. 96th Street, had some concerns. First, she would ask the Planning Commission to understand that hooking up W. 96th Street to Eagle Ridge is because of the Fire Department requirement, but will drastically change the character of the neighborhood and traffic that flows through. It is a tight-knit community and everyone knows one another; she asked that the City be mindful of the decisions they are making and the way it will affect residents. Second, she had a grave concern in being forced to hook up to sewer and water and being charged a hefty assessment fee. She works three part-time jobs, her husband works full- time and part-time and if the City requires them to no longer use their well and sewer, it will cost them a lot of money. She is concerned that there may be others in the neighborhood that also fall into that category. Finally, Dr. Haverly said regarding the reconstruction of W. 96th Street to include sidewalks, her property is one of the end properties on the development and W. 96th Street goes onto her property and uses part of the utility easement. In looking through City Code, Section 18-64 through 18-77, Article 4 describes easements as the front 10 feet of one’s property provided for utilities. Division 5 Section 20-379 defines utilities as sewer, gas, electrical, and water systems but it does not say that the City may use her property for roads and sidewalks. She then did a search on eminent domain and could not find it. She wonders what recourse the City has for using her property for this street and sidewalks and every single resident will be giving up a hunk of their front yards in order to accommodate this, which is eminent domain and requires some fiscal compensation. Vice Chairman von Oven noted she keeps referring to 76th Street and he does not know what that is. Dr. Haverly replied she is nervous and she meant W. 96th Street. She asked to show the ghost plat of the subdivision and pointed out her property and utility easement; this does infringe on her property and they can definitely come to some kind of agreement or conclusion. Elaine Meyering, 1050 Homestead Lane, saw on the map that they are proposing a road through their cul-de-sac and stated they are against that and do not want that to go through. She noted on the map showing the future that a road may go through the cul-de-sac on Homestead Lane and on Flintlock Trail for future development of the area. If that happens, she wonders when and if they would be assessed fees for City sewer and water, as well as curb and gutter. She also asked if the properties would stay the way they are on Homestead Lane or rezoned into smaller lots. Commissioner Noyes asked to clarify in extending W. 96th Street to the west it appears that would potentially connect with Flintlock Trails and Homestead Lane both coming in from the south. Ms. Meyering replied yes. When looking at the map A, B, C, D, she asked if those are water towers. Mr. Henricksen said from the 2040 Comprehensive Plan this property was analyzed to have a water tower on it at some location and the developer’s engineer has provided three locations that Planning Commission Minutes – July 20, 2021 6 would meet the requirements. There will not be a need to install three water towers but there are three possible locations identified. He showed the most ideal location from staff’s point of view. Ms. Aanenson, Community Development Director, noted one of the first things staff does is to show a potential alignment for the street because it is in the Comprehensive Plan that the street must connect. The intention here is that it is transparent that there is a potential for connection. Will it happen? They will have to decide as the rest of the street comes in, and they know there is a potential for water sites so people can plan for that in the future. It is not the City’s intention to rezone the property on W. 96th Street nor to rezone the property south. The goal in moving forward is as systems fail (septic and sewer) there is another alternative to provide for those houses, as there have been situations where systems fail and people cannot sell their home. They are always planning for other options but does not mean that it has to go through at that time; they are saying there are options to provide sewer and water access to those and some of those decisions are also made by the Fire Department. She clarified today they are looking at this project to show what could happen over there. Kim Lee, 600 W. 96th Street, noted four bullet points on a document, regarding construction traffic on W. 96th Street. Included is further deterioration of the road, and she noted they would like to maintain the current cul-de-sac with no through traffic. The proposed construction access from Powers Boulevard in line with the current ghost plat, they know the construction is not just the first 21 houses but will eventually extend and all of that traffic will go on for 3-5 years as this is not something short-lived. If it was at least looked at through Powers, there is no one there, and then W. 96th Street won’t be affected until possibly 2026. She noted they know it is eventually coming, but none of those homes would be interrupted until that time. Chairman von Oven closed the public hearing. Commissioner Alto asked if it is determined that all construction traffic would enter through W. 96th Street or would it be split between Eagle Ridge. Mr. Henricksen replied ideally it would be split. It is not atypical for public right-of-ways to be used for construction access when they see developments extending from existing right-of-ways. Through construction planning to have two routes and access points to the development would be sought after. With W. 96th Street being slated for reconstruction in the future, it is an ideal location to have construction traffic. Commissioner Alto asked if it is possible to ask the developer to use the Powers connection as a construction road. Mr. Henricksen noted they looked at that possibility but found it infeasible with the proposed development and not necessarily prudent or reasonable. Commissioner Reeder asked what made it infeasible. Mr. Henricksen replied it comes into construction means and methods in looking at getting a delivery when there is a road that is unplatted and does not have addresses. Planning Commission Minutes – July 20, 2021 7 Assistant City Engineer, George Bender stated it is someone’s property and to make the requirement – rather than request – as a condition of the development goes to the reasonability of the request. Commissioner Noyes asked if the western part was being developed now, would the access come down W. 96th Street for construction? Mr. Henricksen replied no. It would come off Powers Boulevard. He noted reconstruction of W. 96th Street is highly contingent on the future developments. Mr. Generous clarified the westernmost portion is guided for office development; it is really market-driven and if someone wanted to come in and do that they would probably require making the connection from Powers Boulevard. He clarified there is a large ridge right there that will have to come down to meet the 7% slope requirements of the City. Commissioner Skistad asked if W. 96th Street is currently a mound and well system for sewer and water. Mr. Generous clarified they have sewer connection, but not everyone has water. Mr. Henricksen replied they have tanks in their backyard which then flow to the gravity system in W. 96th and then goes to Lift Station 20 and gets pumped across Highway 101 to another gravity system. It would be ideal to have a normal sewer pipe there as the tanks are an area of Infiltration and Inflow (I and I) so they are seeing surface water and ground water leeching into the sanitary system. It is an issue the City is dealing with as a whole but W. 96th Street has exhibited a higher I and I than normal and it is believed to be tied to the tank system tied in there. Commissioner Reeder asked what the policy is if and when they put that pipe in. Do they require a hook-up? Mr. Generous replied if one is within 150 feet of the sewer line, they are required to connect. A well may be maintained until it fails and then one cannot drill a new well but would have to connect. Mr. Henricksen believes the 150-foot requirement is also linked to new construction. Vice Chairman von Oven noted this Commission has approved two variances in the last six months in his neighborhood which has resulted in a ton of construction traffic and drives him nuts. However, it was the right thing to do because the variances followed the City plan and it is the right of the property owner to do with their property what is allowed by the City. From his point of view, the Commission has a set of plans and variances before it that do not vary widely from what the City expects and that a property owner is not going beyond their rights. He does not see anything on the map that City Code gives reason to say one cannot do that, which is also why he believes staff is recommending approval for City Council. Planning Commission Minutes – July 20, 2021 8 Commissioner Reeder thinks the construction traffic on W. 96th will be outrageous. He has lived with this in the past and he thinks it will be a large problem for the City for the five years it takes for things to be built. Vice Chairman von Oven does not disagree but he does not feel it is within their rights to force the property owner to go in through Powers. Commissioner Alto moved, Commissioner Johnson seconded that the Chanhassen Planning Commission recommends that the City Council approve the rezoning of the development from Agricultural Estate District (A2) to Single-Family Residential District (RSF); preliminary plat with variances for street width, front yard setback (Lot 1, Block 1), wetland setback (Lot 1, Block 1) and street frontages (Lots 3 through 9, Block 1) subject to the conditions of the staff report and adoption of the Findings of Fact and Decision. All voted in favor and the motion carried unanimously with a vote of 6 to 0. PUBLIC HEARING: CONSIDER A REQUEST TO REZONE PROPERTY FROM AGRICULTURAL ESTATE DISTRICT (A2) TO SINGLE-FAMILY RESIDENTIAL DISTRICT (RSF) AND SUBDIVISION APPROVAL OF TWO LOTS AND ONE OUTLOT WITH VARIANCES FOR A PRIVATE STREET AND PRIVATE STREET WIDTH AT 9197 EAGLE RIDGE ROAD Mr. Generous presented the staff report and said Planning Case #2021-15 is a rezoning and subdivision approval to create two lots, one for the existing home and the other for a new building site. The approval comes with variance requests for a private street, as currently the lot is accessed via a private street and they would extend that to serve the two lots. There is also a request to have less than a 20-foot wide private street because of retaining walls on site in the wetland. The site is guided for residential low density which permits densities of 1.2 to 4 units/acre. Sewer and water are stubbed to the end of the private street but are not connected to the homes. There are wetlands in the northeast and south side of the property. Mr. Generous spoke about utilities and tree removal. Mr. Henricksen reported there are no public utilities or street connections. As presented and shown, the grading plan is feasible and meets the ordinances. Construction plans will require some updates and will be reviewed during the building permit process. Mr. Generous stated City Code permits the use of private streets for up to four single-family homes. He advised the applicant that they need the Fire Marshal to sign off on the variance for design standards for a private street. The applicant is proposing to use wetland buffering which the Watershed District must approve. Staff is recommending approval of the rezoning and the subdivision with the variance for the private street and private street width subject to the conditions of the staff report and adoption of the Findings of Fact and Recommendation. Commissioner Skistad asked how long the private road would be. Planning Commission Minutes – July 20, 2021 9 Mr. Generous replied about 200-300 feet. Commissioner Alto asked if the trail across Highway 101 that plans to connect to Bandimere Park will be constructed. Mr. Generous replied not as part of this development. Currently, there is an underpass under Highway 101 and they would be looking for the connection in the future. Commissioner Noyes asked if that connection is in an easement or on an outlot that the City would own. Mr. Generous noted that is up to the developer. The City would prefer it as an outlot that the City would own, but if the developer wanted to keep it, then they could and place a drainage, utility, and trail easement for a future trail alignment. The Council discussed trail crossings and their preference is not to have trail crossings mid- block. Mr. Henricksen noted the newly formed Traffic Safety Committee developed earlier this year is developing a safe crosswalk policy which deals directly with mid-block crossings to have certain criteria for when and if they are installed and what type of improvement. Martin Schutrop, Schutrop Building, noted there will be a shared agreement on the driveway for maintenance and plowing. The current house has already been sold and will be remodeled and updated. Vice Chairman von Oven opened the public hearing. Vice Chairman von Oven closed the public hearing. Commissioner Noyes moved, Commissioner Skistad seconded that the Chanhassen Planning Commission recommend that the City Council approve the rezoning from Agricultural Estate District (A2) to Single-Family Residential District (RSF), a two-lot, one outlot subdivision with a variance for the use of a private street and private street width subject to the conditions of the staff report; and adoption of Findings of Fact and Decision. All voted in favor and the motion carried unanimously with a vote of 6 to 0. APPROVAL OF MINUTES: Commissioner Noyes noted the minutes of the Planning Commission meeting dated July 6, 2021 as presented. ADMINISTRATIVE PRESENTATIONS: Ms. Aanenson presented highlights of action taken by the City Council on planning matters. At the last Council meeting, the Avienda Final Plat was approved, and there was a Metes and Bounds subdivision for a salon. Regarding the interim use for the driving range, the City sent out Planning Commission Minutes – July 20, 2021 10 for jurisdictional review and received a response from the DNR that they had no comments from the Biology and Wildlife person. During the City Council meeting out of the blue, someone from the DNR Wildlife got up and noted he had no problems and had met with the applicant the previous Friday. The City sent a letter that it would have been nice if they had communicated that with them. ADJOURNMENT: Commissioner Noyes moved to adjourn the meeting. All voted in favor and the motion carried unanimously with a vote of 6 to 0. The Planning Commission meeting was adjourned at 8:46 p.m. Submitted by Kate Aanenson Community Development Director
