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 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 add two single- family lots to the preliminary plat with variances from the tree replacement requirements. The applicant has added 1.08 acres with the parcel at the end of West 96th Street (731 W. 96th St.). APPLICABLE REGULATIONS Chapter 18, Subdivisions Chapter 20, Article XII, “RSF” Single-Family Residential District BACKGROUND On October 25, 2021, City Council approved a grading development contract for the project to permit the developer to initiate site grading and tree removal in preparation for the infrastructure improvements for the development. On August 9, 2021, City Council approved: The ordinance rezoning the development from Agricultural Estate District (A2) to Single- Family Residential District (RSF) (Blocks 1 and 2); 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 thru 9, Block 1). 88347 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 3 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. On August 14, 2020, the 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 Outlot 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, 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 in Outlot G north of the large wetland complex On July 10, 1995, 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-acre property which included the field surveyed area of approximately 20 acres proposed to be developed (all of Block 1, and portions of Outlots A, B, C, D, E and F, and all newly dedicated right-of-way) and is in general conformance with the requirements of Sec. 18-40. The remaining 117 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 it was original platted with the Butternut Ridge Addition in 1995 (Lot 1, Block 1). As such, the developer is not proposing to vacate the public drainage and utility easements (DUE) associated with the existing residence; further discussion regarding this DUE can be found under 89348 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 4 the “Drainage and Utility Easements”section of this report. All other recorded public DUE within the platted area, along with all other easements identified, must be vacated before, or concurrently with, the recording of final plat. The easements to be vacated include, but may not be limited to, those identified on the existing conditions 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 96th Street from abutting properties. Also, the driveway to any existing residence must be surfaced with bituminous, concrete or other hard surface materials in accordance with Sec. 20-1122 of City Ordinance. A wooden bridge structure located within Outlot B in the conveyance channel between Wetland 2 and Wetland 3 near Lot 5, Block 1 was observed during the City of Chanhassen’s SWPPP inspections. A dock was also observed on the west edge of Wetland 3. The bridge structure and dock shall be added to the existing conditions survey. No documentation for the bridge structure was submitted as part of the proposed subdivision. Bridge rating, as-builts, and a water-crossing permit from the Riley Purgatory Bluff Creek Watershed District (RPBCWD) will be required if the bridge is to remain in place. Without further documentation, the City cannot verify the bridge will be safe for citizens and maintenance crossings as Outlot B will be owned by the City. 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 90349 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 5 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 (Single-Family Residential), 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 that permits only single-family homes, and is the zoning approved for the balance of the subdivision. While the R4 District permits single-family homes, it also permits twin homes that would be inconsistent with the surrounding development. The RLM District permits single-family homes, as well as twin homes, townhouses and attached housing, but the RLM District also requires that large areas of upland 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. 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. 91350 Erhart Farm –775 and 731 W. 96th Street April 19, 2022 Page 6 SUBDIVISION The applicant is proposing a 24 lot, eight outlot subdivision with dedication of public right-of- way. Except for Outlots A and B, which will be preserved for permanent open space, the outlots will be developed in the future through another subdivision review process. Preliminary Plat STREETS The proposed subdivision has access to public right-of-way via Eagle Ridge Road to the north and 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 as reimbursement for the removal of the temporary cul-de-sac the $33,750.00 escrow which was collected from Foxwood for the removal work along with work associated with extending the street and sidewalk 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 network. The proposed subdivision, along with the future additions, are bound by Powers Boulevard to the west and CSAH 101 to the east, which are both minor arterials. 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 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 92351 Erhart Farm –775 and 731 W. 96th Street April 19, 2022 Page 7 development, which conceptually takes into account the connection of Eagle Ridge Road to Powers Boulevard, highlighted in purple and seen below: The ghost plat of the future subdivisions adequately illustrates the nature and character required of the minor collector by providing an equal mixture of mobility and access similar to its predecessor, Foxwood. Foxwood was approved with a driveway-to-road-length of 1.3 driveways for every 100 feet of road; the proposed Erhart Subdivision’s ghost plat illustrates a concept of 1.2 driveways for every 100 feet of road. A majority of the streets and their rights-of-way are proposed to meet City standards,however the small ring road abutting Outlot A, “Eagle Ridge Way”, is proposed to be a 26.5-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. Additionally, the applicant is proposing No Parking” on one side of Eagle Ridge Way, which will require the width to be updated to 26 feet from face-of-curb to face-of-curb which is 12 inches from back-of-curb with the surmountable curb design. When the previously approved preliminary plat was submitted, staff originally proposed a recommendation to require a sidewalk along “Eagle Ridge Way” in order to promote pedestrian safety due to the variance request for a narrower street width, however this recommendation was not required in the final order of the previous preliminary plat request for the subdivision.Per 93352 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 8 City Ordinance, all sidewalks are to be maintained by the abutting property owner. As the majority of the sidewalk proposed with this subdivision abuts Outlots, it will be the responsibility of the owner of these Outlots to maintain the sidewalks, which includes snow and ice removal. The previously approved preliminary plat illustrated street designs that would be stubbed out for future road extensions when the property to the west develops. These stub outs were required to be wholly incorporated in the right-of-way boundary on the plat. Additionally, “Future Street Extension” signs attached to barricades were required to be installed at these locations. The updated preliminary and final plats provided show these updates for all but one location – the southern intersection of Eagle Ridge Road and Eagle Ridge Way. Final plans must be updated accordingly, at a minimum the barricade and “Future Street Extension” sign must be installed. The preliminary and final plat and associated construction plans were sent to Carver County for the development and the County responded with a review memo dated January 10, 2022. All comments and requirements set forth by the County must be addressed prior to the City considering approval of the final plat. DRAINAGE AND UTILITY EASEMENTS The preliminary and final plat provided illustrates mostly typical public drainage and utility easements (DUE) along the proposed subdivision’s lot lines with five foot DUE along the side and rear lot lines and 10 foot DUE along the front lot lines. Rear lot lines on Lots 1-16, Block 1 are atypical to accommodate proposed wetland buffers, conservation easements and stormwater improvements. 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), and DUE in the rear yard of Lots 16 and 17 are 20 feet wide; these widths are required in order to provide adequate access for maintenance purposes to the storm sewer system and its appurtenances. However, access to the large stormwater facility which is partially located on Outlot C and partially located on Lots 14, 15, and 16, Block 1 needs to be addressed as further discussed in this report under “Stormwater Management” of this report. Ideally, the stormwater facility would be wholly encompassed within an Outlot, along with the maintenance 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. Regardless if the BMP is encompassed by public DUE or an Outlot, the boundaries must encompass an area that is a minimum of one foot higher than the 100-year HWL in order to provide resiliency. The preliminary and final plat also illustrate wider areas of DUE between Lots 1 and 2 and Lots 3 and 4, Block 1. These were shown to facilitate stormwater conveyance systems which were proposed to collect stormwater from the impervious surfaces associated with these lots and route it to the public system in the street. Staff finds that these DUE may not be necessary if the 94353 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 9 stormwater conveyance is redesigned to a more typical draintile conveyance method as allowed through current City Specifications and Detail Plates. If feasible, the final plans and final plat shall be updated accordingly. While DUE was platted in association with Lot 1, Block 1 of the Butternut Ridge Addition which is being proposed to remain during this phase of the Erhart Farms development, there is no DUE connecting the Butternut Ridge lot to the DUE or right-of-way being dedicated with the Erhart Farms subdivision. Without a contiguous connection of DUE there would be no viable route for extending utilities to the lot. The applicant must update the final plat to include DUE that facilitates a contiguous connection between the newly dedicated DUE or right-of-way with Erhart Farms and the existing Block 1 Lot 1 of Butternut Ridge. The applicant is proposing to encompass the future public sanitary sewer lift station, discussed in more detail under the “Sanitary Sewer and Water Mains” section of this report, with DUE within Outlot F. In order for the City to best maintain such a critical public facility, the lift station needs be placed in an Outlot that the City will own and maintain in perpetuity. This Outlot should extend to the southernmost property line based on the current proposed location and dedication will be required with the recording of the final plat. GRADING AND DRAINAGE 95354 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 10 Grading A portion of the property was issued Interim Use Permit #2021-03 (IUP) on December 4, 2020 by City Council for grading operations, with an amendment and extension being approved on October 21, 2021. This IUP was requested for the dredging of Wetland 2, north of the subdivision. All terms and conditions of the IUP shall remain in effect until the permit is terminated. While the IUP did not directly impact any of the proposed 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 with this subdivision. Wetland soils, or hydric soils, are typically high in organic materials and do not lend themselves to suitable engineering fill. On October 25, 2021 the City Council approved a development contract for grading purposes Grading DC) along with the Erhart Farms Phase 1 Mass Grading and Tree Removal Plan dated October 13, 2021, contingent upon updates based on the conditions of the Grading DC. The request for the Grading DC was made by the developer in order to begin mass grading and tree clearing operations while the final plat and final construction plans were being finalized. While tree clearing operations in association with the Tree Removal Plan were initiated, no mass grading has yet occurred in association with the Erhart Farms Phase 1 Mass Grading plans. In order to efficiently and more effectively administer the requirements of the Erhart Farms development, staff is recommending consolidating the approved October 25, 2021 Grading DC along with all of its applicable conditions with the Development Contract required to be entered into upon approval of the final plat for Erhart Farms. The applicable conditions previously approved with the Grading DC purposes are enumerated under the “Applicable Recommendations from Approved Development Contract for Grading Purposes Passed by City Council 10/25/2021” section of this report. The developer is proposing to mass grade a majority of the site in order to construct the public streets, house pads and stormwater management areas. However, Lots 4-10, Block 1 are being proposed to be custom graded, which will be completed during the building permit phase. Nonetheless, the grading plans adequately illustrate the feasibility of the custom graded lots in association with the mass grading plans provided. As such the custom graded lots are acceptable and the approach can be approved in accordance with City Ordinances. While the 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 landing locations is 3%. 96355 Erhart Farm –775 and 731 W. 96th Street April 19, 2022 Page 11 A geotechnical report with soil borings conducted by Haugo Geotechnical Services, dated May 22, 2021 was provided by the developer. A geotechnical engineering firm shall be on-site during grading operations to ensure the City’s Standard 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 adhering to the recommendations of the soil engineer on site. Changes to grades shall be submitted to the City for review and approval. Drainage and Storm Sewer The proposed project area is bounded by wetlands on the northern and western sides. In the existing condition, stormwater runoff generally flows from the southwest to the northeast with the majority of stormwater outletting to Wetland 3. The proposed condition maintains the existing drainage patterns. The proposed design uses a storm sewer trunk-line to collect and convey the majority of the sites stormwater to a combination wetpond/infiltration basin best management practice (BMP) which treats the stormwater before it discharges to Wetland 3. The proposed design also incorporates a small filtration basin BMP located on Lots 2 and 3, Block 1. The filtration BMP treats stormwater before it drains to Wetland 2. This BMP will be privately owned and maintained, and as such will be required to have an Operation and Maintenance Agreement executed and recorded concurrently with the final plat. The development plans show storm sewer pipes, including draintile, with slopes less than 0.50%. Pipes with shallow slopes are difficult to construct and can cause issues with future maintenance because storm sewer velocities are not adequate for cleaning. Pipe slopes over 0.50% are recommended in areas not restricted by elevation. 97356 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 12 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). As this wall is located within a lot that is proposed to be custom graded, construction plans associated with the wall be reviewed and approved during the building permit process. 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 Section 19-145 of City Ordinance shall be submitted for the grading operations of the subdivision. The developer provided an ESCP along with a Stormwater Pollution Prevention Plan (SWPPP) which were approved by the City in conjunction with the Grading DC as mentioned previously under the “Grading” section of this report. As previously mentioned, the approval of the Grading DC was contingent upon updates based on the conditions of the approval. These conditions, which are being recommended to be incorporated as part of the development contract required for the subdivision, require that updates to the SWPPP and ESCP be provided prior to grading operations commencing. SANITARY SEWER AND WATER MAIN The subdivision has access to a 12” 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” trunk main within Powers Boulevard when the property to the west develops. As such, the developer will be required to extend the 12” trunk water main and the City will reimburse the developer for the cost of oversizing this extension along with its appurtenances as an 8” main would have been sufficient in supplying the subdivision’s water demand. The 12” trunk main will follow the street corridor to the south within Eagle Ridge Road as it will eventually connect to a future water tower location within the future subdivisions as guided for in the 2040 Comprehensive Plan. Water main stubs will be provided for future extensions when the property to the west develops, along with a stub leading towards 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 when future development to its south (i.e. the currently proposed Erhart Farms subdivision) occurred the temporary lift station would be removed and gravity sanitary sewer would be constructed to a planned permanent lift station on Powers Boulevard in accordance with the 2040 Comprehensive Plan. The developer 98357 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 13 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 F abutting 96th Street rather than constructing the gravity system to Powers Boulevard. The City reviewed this proposal as it would eventually eliminate Lift Station 20 at the end of 96th Street which, when build-out of the area is complete, would not increase the net number of lift stations the City owns and maintains. After iterations of reviews and meetings between the City and the developer and their engineers, it was determined that this approach is feasible. The lift station has been preliminarily designed to accommodate sewerage flows from Foxwood, the proposed Erhart Farms subdivision, the future Erhart Farms subdivision(s), and 96th Street. The 96th Street area was analyzed based on its current zoning and the possible maximum units per acre if the area developed. As the lift station will facilitate sewerage flows from areas not required by the development (i.e. flows from 96th Street and its potential future build-out and the potential of a lot split at 9199 Eagle Ridge Road), the City will reimburse the developer a proportion of the cost to construct the lift station based on sewerage flows (i.e. residential units) along with reimbursement for the cost of stubbing out the sewer to 96th Street. The proportion was calculated to be 71% the Developer’s cost and 29% the City’s, as follows: Because the developer will be responsible for the portion of Foxwood’s sewerage flows, the 48,725.04 collected from the Foxwood development for the future build-out of a permanent lift station will be reimbursed to the developer, along with the $10,000.00 escrow that was obtained from the Foxwood development for the abandonment of the temporary lift station. The developer and their engineers will be required to continue to work with staff in the final construction plans and details of the proposed lift station along with its location. Items such as the electrical and control panels for the lift station, SCADA pole location and path checks, final details regarding the size and layout of the access, exact location of the force main, a detailed breakdown of the costs of the lift station, and other construction related items associated with the lift station still require finalization prior to approval of 100% construction plans. Staff has provided the applicant and their design team construction related comments based on the most recent submittal received to date which are the plans dated 10/17/2021 received with the December 2021 submittal. 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 backfill and compaction techniques must be provided. Lastly, as the extension of the utilities are from the Foxwood development and the City has yet to accept these utilities for public ownership and maintenance, issuance of a Notice to Proceed for utility work cannot be granted for the proposed development until Foxwood’s utilities have been accepted.

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), and runoff rate control for the 2-, 10-, and 100-year storm events. The proposed development is located within the RPBCWD and is therefore also subject to the their rules and regulations. A Stormwater Management Study dated September 28, 2021 was submitted by the applicant to the City and RPBCWD as part of the final plat review. The applicant received conditional approval from RPBCWD on October 6, 2021. An approved RPBCWD permit is required before grading or utility construction work can be started. The water quality rules appear to be met with the use of a baffle, sump, filtration basin, and wet pond/infiltration basin. Eighty-eight percent (88%) of TSS and 87% of TP is removed from the system, via MIDS modeling, however the modeling does not include baffles the infiltration basin design that will act to increase removal rates. The applicant will need to update MIDS and resubmit the models in their native form to confirm the City’s water quality rule is met. The Stormwater Management Study and supporting HydroCAD models show that the proposed development meets the City’s stormwater rate control rules. Peak runoff rates for the proposed condition are reduced when compared to the existing condition for the 2-, 10-, and 100-year storm events. The NPDES construction permit and RPBCWD Stormwater Rule both regulate water quality volumes for development projects. RPBCWD rules are stricter, requiring 1.1-inch abstraction for new and reconstructed impervious for the entire project area. The proposed project will have a total impervious area of 5.35 acres requiring 21,300 cubic feet of abstraction volume. The proposed infiltration basin provides 27,700 cubic feet of abstraction which exceeds the required volume. Infiltration rate testing was conducted onsite on September 24, 2021 by Haugo Geotechnical Services. Two test sites located at the proposed infiltration basin showed infiltration rates of 2.16 in/hr and 3.24 in/hr, which far exceed the 0.375 in /hr rate needed to drain the BMP in the 48 hour regulated timeframe. It should be noted that infiltration rates this high are not typical in Chanhassen and are usually associated with sandy soils, which are ideal for infiltration practices. The proposed wet pond/infiltration BMP treats the majority of the stormwater runoff from the development including runoff from public ROW and private property. As such, this BMP will be publicly owned and maintained. The proposed maintenance access route to the BMP is off of 96th Street. In order to gain access to the outlet control structure (OCS) and rip rap emergency 100359 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 15 overflow (EOF) the berm between the wet pond and infiltration basin has to be traversed. The elevation of the berm is 984.0, which is 1.5 feet lower than the modeled high-water level of the pond (985.5). This configuration would restrict maintenance during flooded conditions. Stormwater infrastructure (pipes and structures) are located within the access route. There is a high probability of damaging stormwater infrastructure during routine pond maintenance and therefore the storm sewer shall be offset from the maintenance route. The developer must work with staff to improve the public stormwater facility’s access route along with providing adequate justification that the maintenance access route section can support the weight of maintenance equipment. The BMP has an atypical design where the normal water level (NWL) 982.0 of the wet pond is 1.5 feet higher than the bottom of the infiltration basin 980.5. This configuration creates a hydraulic head difference, which will act to convey water through the berm under normal conditions. This is especially true with the high hydraulic conductivity/infiltration rates observed onsite. Water migration through the berm could cause stability problems. As such, the City is recommending an optimized configuration where the NWL of the wet pond matches the bottom elevation of the infiltration basin, and the berm is elevated to allow access during flooded conditions. The developer must work with staff to improve the public stormwater facility’s operation and layout to the maximum extent possible within the given the limitations of the site and RPBCWD regulations. The filtration basin BMP located on Lots 2 and 3, Block 1 is to be privately owned and therefore will require an Operations and Maintenance (O&M) Plan. An O&M Plan was not included in the submittal. The plan that identifies the maintenance schedule, responsible party, and should include information on how the system will be cleaned out. The applicant must work with staff to create an approved O&M Plan that will be signed prior to recording the final plat. STORMWATER UTILITY CONNECTION CHARGES City Ordinance 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; 2022 rates are $8,830.00 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; 2022 rates for partial hookup fees are $691.00 per unit for sanitary sewer and $2,562.00 per unit for water. The remaining partial hookups fees are due with the building permit. 101360 Erhart Farm –775 and 731 W. 96th Street April 19, 2022 Page 16 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: $8,830.00 per acre c)A portion of the water hook-up charge: $2,562.00/unit d)A portion of the sanitary sewer hook-up charge: $691.00/unit e)Park Dedication Fee: $5,800.00/unit f)Street Lighting Charge (for electricity): $300.00/light g)GIS Fees: $100 for the plat plus $30 per parcel h)Final Plat Process (review and recording of Plat and DC): $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, Block 1 shows that the 5-foot pervious nature trail encroaches 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. 102361 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 17 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 thru 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 The applicant for the Erhart Farm Phase I development submitted tree canopy coverage and preservation calculations. Total upland area (excludes wetlands, bluff)21.184 acres Baseline canopy coverage 84% or 17.83 acres Minimum canopy coverage required 55% or 11.65 acres Proposed tree preservation 24% or 5.1 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 11.65 acres Less canopy preserved 5.1 acres Minimum canopy coverage to be replaced 6.55 acres Multiplied by 1.2 7.86 acres or 342,381 sf Divided by 1089sf =Total number of trees to be planted 314 trees The applicant has submitted a landscape plan showing a total of 314 trees to be planted in the development. Any trees planted outside of the final plat area will not be counted towards reforestation quantities. There are no buffer yard landscaping requirements for this development. The applicant has not provided quantities for any species proposed to be planted. The applicant must verify that species diversity requirements are met for the development, namely no more than 10% of any one species, no more than 20% of any one genus and no more than 30% of any one family. A revised landscape plan with a complete Plant Schedule listing quantities, plant names, sizes and survey symbol must be submitted to the City for approval prior to a Notice to Proceed. In the submitted Final Plat narrative dated December 17, 2021, the applicant has proposed conservation easements on Lots 2 thru 10, Block 1 and staff would support this. The existing 103362 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 18 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 the remaining area of trees on Lots 4 thru 10. Lots without any remaining trees, which would include Lots 1 thru 3, 11 thru 18 are proposed to have reforestation plantings in the rear yards. These trees will be a mix of potted, transplanted and balled and burlapped trees planted in a random pattern to replicate a native woods. The plantings will be crucial in meeting the reforestation requirements to replace lost canopy cover on over half of the lots. To ensure that these trees grow and become canopy cover, staff recommends that the proposed Conservation Easement extend over the Reforestation Mix planting areas. The applicant shall submit a plan showing the proposed Conservation Easement for city approval and shall be recorded concurrently with the final plat. As part of the 314 trees required for reforestation, the applicant is including 27 trees that were planted in 2021 as part of the replacement plantings for a haul road from the applicant’s wetland project. When the lots are inspected for the required number of trees, any of these trees found to be less acceptable than standard nursery stock or dead will be required to be replaced with 2.5” nursery stock. Tree plantings have been located on the west side of the proposed collector. The 18 proposed plantings shall be relocated to the ‘reforestation mix’ area on the 18 lots. No plantings will be allowed on the west side of the collector road due to future construction in that area. Trees planted in unbuilt lots have low survivability due to lack of care. Additionally, once construction starts on a lot, protecting the tree is extremely difficult and damage to the tree is easily done. The trees that will be required for those lots must planted in a future phase after construction is completed on the lots. The applicant has requested a variance from the minimum size requirements for reforestation plantings. Staff can support the variance for allowing the 110 proposed nursery stock potted trees. Staff believes this approach can facilitate a more natural layout for reforestation plantings. Using tree stock of different sizes will foster structural diversity and serve to bear some resemblance to a naturally occurring wooded area. The applicant has requested a variance from supplying certified nursery stock for the development. As proposed in the landscape plan, the applicant would transplant 84 trees found on site in addition to the 27 transplanted trees installed in 2021. This equates to 35% of the proposed trees to be planted. Staff recommends that no more than 10% of the total required plantings come from uncertified nursery stock. Certified nursery stock is inspected by the Minnesota Department of Agriculture for any signs of disease or pests. Plant materials found to have diseases or pests that can harm or kill landscape plants are treated or destroyed to ensure that all plant stock sold by nurseries is healthy and safe for the environment. While transplanting trees on site may be at less risk to introducing new pests or diseases, there is no guarantee that this is so and could potentially spread diseases or pests from one area of property to another. In addition to protecting the vegetation health, plant stock from a commercial nursery is required to meet criteria for proper tree health, growth and structure. There are minimum requirements for 104363 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 19 size, root growth, and branching structure. These criteria ensure that the tree is of the best possible quality when planted and is set up for good health and longevity. If there are native trees on site that meet the minimum proposed diameter of 2.5” and are without major structural defects, then the applicant can identify transplant trees for approval by the city. The applicant may have up to 10% of the total required reforestation total originating from uncertified, wild stock in addition to the 27 transplanted trees already installed. This 10% equates to a total of 31 trees to be sourced on site for transplanting. A total of 230 trees will be scheduled for planting within the ‘reforestation mix’ area shall be planted as one planting project. The 230 trees are comprised of 110 ¾”-1” nursery potted trees, 89 developer installed 2.5” B&B nursery stock trees, and 31 on-site transplants. A tentatively scheduled planting date as well as a maintenance plan that includes regular weekly watering will be required to be submitted prior to the Notice to Proceed. 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 CSAH 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 continue 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. Outlot A shall be retained by the developer or Homeowners Association as a private open space subdivision amenity. 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 CSAH 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 CSAH 101. 105364 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 20 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. A “5-foot pervious nature trail” is shown that connects to the 96th Street right-of-way and terminates at an existing stormwater facility that treats runoff from CSAH 101. A permanent trail, and drainage and utility easement along the rear lot lines of Lots 5 thru 17 shall be dedicated with the final plat. Trail development may occur in the future. 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 23 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 2022 single-family Park fee of $5,800 per unit, the total Park fees for Erhart Farm would be $133,400.00. Outlot B shall be donated or dedicated to the City of Chanhassen to be part of permanent open space around the wetland complexes. MISCELLANEOUS 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. Fire hydrant locations and distancing look to be appropriate. No landscaping (trees, shrubs, plants) to be done within three feet in all directions around each hydrant. 2. Roads 20-26 feet wide will need to have No Parking Fire Lane signs on both sides of the road. 3. Elevation drops and grading for roads will need to meet Fire Access road maximum of 10%. 4. No combustible construction (wood) can begin until fire apparatus access roads are approved (temporary is ok) and hydrants are installed and active/usable. Foundation work is acceptable. 5. May not block emergency access or fire hydrants during construction at any time. 106365 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 21 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. 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 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. 107366 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 22 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. 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.

Approved 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 and 30-foot buffer setback VARIANCE The applicant received approval for the following variances as part of the original subdivision: 1. Seven lots with less than 90 feet of frontage (Lots 3 thru 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. As part of the amended preliminary plat to include the parcel on 96th street within the subdivision, the applicant is requesting a variance from the tree replacement requirements for the development. 110369 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 25 Variance findings for subdivision (tree replacement requirements): a. The hardship is not a mere inconvenience; b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land including trees; 111370 Erhart Farm – 775 and 731 W. 96th Street April 19, 2022 Page 26 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. 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); and preliminary plat with variances for tree replacement requirements 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. Fire hydrant locations and distancing look to be appropriate. No landscaping (trees, shrubs, plants) to be done within three feet in all directions around each hydrant 2. Roads 20-26 feet wide will need to have No Parking Fire Lane signs on both sides of the road. 3. Elevation drops and grading for roads will need to meet Fire Access road maximum of 10%. 4. No combustible construction (wood) can begin until fire apparatus access roads are approved (temporary is ok) and hydrants are installed and active/usable. Foundation work is acceptable. 5. May not block emergency access or fire hydrants during construction at any time. Engineering 1.

Request for Rezoning from Agricultural Estate District (A2) to Single-Family Residential District (RSF), Subdivision Approval creating 24lots and eight outlots with a Variance from the tree replacement regulations. On April 19, 2022, the Chanhassen Planning Commission met at its regularly scheduled meeting to consider the application of Black Cherry Development, LLC for an amendment to an approved preliminary 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 (A2). 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 land use and housing goals of the 2040 Comprehensive Plan; b. The proposed use is or will be compatible with the present and future single-family residential and open space 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, but will enhance the residential character of the area; 117376 2 e. The proposed use can be accommodated with existing and proposed 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 the 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; b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land including trees; 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; 118377 3 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.The planning report #2021-1A2 dated April 19, 2022, prepared by Robert Generous, et al, is incorporated herein.

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. The applicant has acquired a second existing residence and is proposing to adjust the lot lines and subdivide. 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. FINAL PLAT REQUEST The proposed development plan consists of a low-density single family residential subdivision with 19 single family lots of which 18 are new. The proposed development is consistent with the City’s Single- family Residential District (RSF) and will provide a per acre unit density consistent with the City’s Comprehensive Plan land use for the property. The applicant has recently acquired an existing single-family lot with PID 250252400. The applicant requests that the additional lot be preliminarily subdivided and final platted concurrently with this final plat application. The applicant proposes creating 2 additional lots than were previously approved. A preliminary plat request of 22 single family lots (21 new) was approved on August 9th 2021. Block 1 lots 1-17 are included in this final plat request. A Riley Purgatory Bluff Creek Watershed District Permit was Conditionally approved at the October 6th Board of Managers Meeting. Chanhassen City council approved a Development Contract for Grading purposes on October 25, 2021. 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 18 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 1.33 units per net acre within the proposed new lots subdivision area.

The Chanhassen City Council also approved the variances for the front yard setback (Lot 1, Block 1), wetlands setback (Lot 1, Block 1), and street frontages (Lots 3 through 9, Block 1) at the meeting August 9th 2021. 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) 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 approved at City Council Meeting August 9th 2021, also see Variance Approval 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 127386 Final Plat Submittal December 17, 2021 Erhart Farm – Chanhassen, MN Page 5 of 10 18 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 and C 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. 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. 128387 Final Plat Submittal December 17, 2021 Erhart Farm – Chanhassen, MN Page 6 of 10 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 in Outlot F 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 226 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 final plat development proposal will add 20 new homes (this includes 18 new homes and 2 existing). This will leave additional service capacity for roughly 158 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. 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 wet pond, one infiltration basin, and one filtration 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 wetpond prior to discharging into the basins. The basins 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: 129388 Final Plat Submittal December 17, 2021 Erhart Farm – Chanhassen, MN Page 7 of 10 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 have an approved variance to reduce the principal structure setback to buffer for one lot (Lot 1, Block 1), see Variance Request section of narrative.

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. 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 130389 Final Plat Submittal December 17, 2021 Erhart Farm – Chanhassen, MN Page 8 of 10 The estimated baseline tree canopy coverage for the proposed development area is 84.2% of the net area excluding wetland areas). Per the City code, low density residential is allowed to remove trees to a limit of 55% tree canopy prior to requirement of replacement mitigation. The development plan proposes to maintain tree canopy coverage of 24.1% within the development area and thus tree replacement mitigation is required. The developer proposes to install all of the tree mitigation within the proposed phase 1 development and disturbed areas. The applicant is submitting a Variance to the city code for tree planting requirements. See sperate second variance request narrative. 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 and rear yard lot 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 is creating new public Right of Way for proposed 96th street. There is currently a permanent easement for public roadway, drainage and utility purposes over a section of the Southeast part of the property. There is currently a turn-a-round at the end of existing 96th street that the easement covers. The proposed development is connecting to the existing 96th Street and removing the turn-a-round. The easement will no longer be needed with the proposed public ROW for 96th street. The document number for the easement is 509111. The residents of Foxwood Development, Erhart Farm, and 96th will be able to enter or exit at 96th Street and 101 or Eagle Ridge Road and 101. APPROVED VARIANCE REQUESTS AUGUST 9, 2021 The proposed subdivision has 3 previously approved variances. The approved variances were approved by City Council on August 9, 2021. Please refer to the Erhart Farm Preliminary Plat Application and Narrative for the variance requests. The approved variances are: 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 REQUEST, TREE REPLACEMENT Variance to Section 18 to allow tree replacement plantings to be less than 2.5-inch (overstory) and 1.5-inch (understory) and waive the requirement for “certified nursey stock” for onsite transplants. The variance would not apply to the trees proposed on the lots to be installed with the homes. Variance Explanation and Justification (pursuant to Section 20-58) 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. 131390 Final Plat Submittal December 17, 2021 Erhart Farm – Chanhassen, MN Page 9 of 10 The purpose and intent of the tree replacement is to re-establish a tree canopy lost due to tree removal. Per City code, one tree shall be deemed to provide 1,089 square feet of required canopy coverage. Reducing the size of the initially planted tree does not impact the ultimate canopy value. Also, transplants from onsite do not have risk of introducing insects and/or disease that a nursery tree might, so the need for certification is eliminated. 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. The code calculation for tree replacement for a fully wooded site requires more trees than can be practically planted on the site. The Erhart Farm property being developed is the most heavily wooded portion of the property. Additional tree preservation is not practical as the City has required a collector roadway (with fixed connection points) and a deeper than typical sanitary sewer through this heavily wooded area. The only option to preserve more trees is a no build option and that does not facilitate the City Comp Plan requirements for the extension of Eagle Ridge Road, nor the replacement of the temporary lift station installed in the Foxwood neighborhood. In lieu of requesting a variance to reduce the number of trees required, the request is only for reduction in the size requirement. c. That the purpose of the variation is not based upon economic considerations alone. The wetland buffers, pond slopes, and other proposed re-forestation areas are not appropriate locations for typical 2.5-inch nursery trees. Smaller trees that can be hand planted are more appropriate for these natural (and access restricted) areas. Also, tree transplanted from the onsite much of the site is a tree farm) are fully acclimated to the site conditions. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. The City allowed or facilitated the two dead end roadways (Eagle Ridge Rd and W 96th St) that are now being connected at the City’s direction. The City designated the connection from Foxwood to Powers Blvd as a Collector Road. The City’s trunk sewer plan requires a deeper than typical sanitary sewer through the site. The only portion of the situation that is “created by the landowner” is that the landowner planted a significant portion of the trees that are being removed and is now obligated to replace per City code. e. The variance, if granted, will not alter the essential character of the locality. See comments in (a) above. The number of trees planted will meet the code. Some will be smaller initially, but will rapidly catch up in size to a larger tree as the transplant shock is greatly reduced with a smaller tree. 132391 Final Plat Submittal December 17, 2021 Erhart Farm – Chanhassen, MN Page 10 of 10 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. n/a TIMING/PHASING The applicant was approved for Grading and Tree Clearing on October 25, 2021. The applicant has started to remove trees from the site. The applicant’s contractor will begin mass grading the site beginning spring 2022. Following the mass grading the applicant would begin street and utility construction if the final plat plans are approved by city council. Thus beginning street and utility work late spring 2022. CONCLUSION The applicant respectfully concludes that the request for a final plat 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. 133392 11032456789BLOCK1OUTLOTA11121314151617OUTLOTBOUTLOTEOUTLOT BBLO C K 1 BL O C K 1OUTLOT HEAGLE RIDGE WAY EAGLERIDGEROADEA G L E R ID G EROAD96TH STREETOUTLOTFEAGLERI D G E R O A D18 19OUTLOT D OUTLOT C OUTLOT BOUTLOTBOUTLOT GEXCEPTIONEXCEPTIONEXCEPTIONEAGLERIDGEROADSTATETRUNK HWY.

Comments updated January 10, 2022. June 22, 2021 City of Chanhassen c/o Bob Generous AICP Senior Planner 952-227-1131 bgenerous@ci.chanhassen.mn.us Re: Development / Access Review Comments: Erhart Farm Preliminary Plat – FINAL PLAT – located at PID# 251550022 adjacent to County State Aid Highway (CSAH) 101 (Great Plains Blvd.) and CSAH 17 (Powers Blvd.) Thank you for the opportunity to review the subject development in the City of Chanhassen. Consistent with the County Comprehensive Plan and County Codes, and other official controls of the County, the following are comments and recommended conditions of approval and as potential requirements for any necessary permits to be issued for the project. 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 101/96th St., and CSAH 101/Eagle Ridge Rd. 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. i. Condition applies. TIA required prior to final plat approval. 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 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. i. 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 ¼ 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 138397 needed to determine the recommended and allowable intersection type at the CSAH 17 connection point. 1. Condition applies. No access to CSAH 17 will be allowed or approved until all conditions are met. c. No additional direct access to CSAH 101 is proposed. Additional County review and approval will be required if this condition changes. i. Information. 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 ft. 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. i. Condition applies. Right of way appears consistent with planning guidance. 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 ft. 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. i. Condition applies. Right of way appears consistent with planning guidance. 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. i. Condition applies. Revision required. There is a Drainage and Utility easement missing in Outlot B for the triangle shaped stormwater pond on the west side of CSAH 101. d. County recommends all new, dedicated outlots adjacent to the County right of way be owned by the City. i. Condition applies. Request to confirm Outlot B ownership ahead of final plat approval. 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. i. Condition applies. Request for information regarding proposed noise mitigation measures. 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. i. Condition applies. Additional review and coordination needed for permit approval. 5. The technical details of the final plat, its boundaries and form(s) will need to be reviewed 139398 and approved by the County Surveyor. i. Condition applies for final approval. 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 an Access, 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. i. Condition applies. Additional review and coordination needed for permit approval. 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. i. Information. These are the County’s comments at this time.

MEMBERS ABSENT: Kelsey Alto. STAFF PRESENT: Kate Aanenson, Community Development Director; MacKenzie Young- Walters, Associate Planner; Bob Generous, Senior Planner; Joe Seidl, Water Resources Engineer; Erik Henricksen, Project Engineer. PUBLIC PRESENT: Keith Anderson 8043 Cheyenne Avenue Ben Campion 204 W. 77th Street Mike Werth Techniques Construction Mary and Michael Meuwissen 4265 County Road 123, Mayer, MN Ed Szalapski 850 Pleasant View Road Todd Simning Ador Homes Matt Pavek Civil Site Group Dan Blake Black Cherry Development Tim Erhart 9611 Meadowview Drive, Chanhassen, MN Nick Pekarek 202 Chan View Bryce Marsh PUBLIC HEARING: 204 W. 77TH STREET: CONSIDER A REQUEST FOR A VARIANCE TO PERMIT A SIX-FOOT PRIVACY FENCE Associate Planner Young-Walters gave a presentation on the item, noting the Applicant is proposing a 6-foot high privacy fence within the front yard setback. A 30-foot setback is required off Erie Avenue and fences within the setback are limited to three feet in height if opaque or four feet in height if open construction because it is a corner lot. There is an existing 5-foot high chain link fence that is partially within the required 30-foot setback. The Applicant is requesting to install a 6-foot high privacy fence that would maintain the 5.9-foot setback from Erie Avenue. The justification is that the property does not have a lot of privacy because it has street frontages on both sides. The lot’s triangular shape and non-conforming house placement mean that a privacy fence would not be permitted in most of the rear or side yard under City Code. The Applicant has noted that nearby lots including the corner lot across the street have privacy fences and they do not believe their proposal would negatively impact the neighborhood. Staff believes the overall intent of the fence ordinance is to allow for residents to have private rear and side yards and they view this as an exceptional case where, due to the non-conforming placement of 405 Planning Commission Minutes – April 19, 2022 2 the primary structure, the front yard setback does not align with the front of the house. Staff believes the property’s unique shape and size create a practical difficulty and recommends approval. Chairman von Oven opened the public hearing. Chairman von Oven closed the public hearing. Commissioner Noyes moved, Commissioner Johnson seconded that the Chanhassen Board of Appeals and Adjustments, approves a variance to permit the Applicant to construct a six-foot privacy fence within the front yard setback along Erie Avenue, subject to the conditions of approval, and adopts the attached Findings of Fact and Decision. All voted in favor and the motion carried unanimously with a vote of 6 to 0. PUBLIC HEARING: 6430 PLEASANT VIEW LANE: CONSIDER A REQUEST FOR A SIDE YARD SETBACK VARIANCE TO PERMIT CONSTRUCTION OF AN ADDITION Senior Planner Generous gave a staff report on the item, noting the house is currently built five feet from the side property line on a non-conforming lot and the proposed expansion would still be under the 25% hardcover limit. The Applicant would like to expand the house along the same plane to extend the garage. The proposed expansion creates a tandem garage with interior storage and expands the living area. Mr. Generous checked on four variances regarding nearby properties and only one was granted for the same reason, to expand the house along the existing plane of the structure. The Applicant wants to maintain the integrity of the building. Staff believes the request is reasonable and recommends approval of the five-foot north yard setback variance with an allowance for the 18-inch eaves. Mike Werth is representing the homeowner and said currently the house is over the setback. He showed plans and explained the design choice. Chairman von Oven opened the public hearing. Chairman von Oven closed the public hearing. Commissioner Noyes stated another case was approved that was almost an identical type of variance request of an addition on the same plane, so there is some precedent they are following. It seems like a reasonable solution. Chairman von Oven said if the neighbors are good with it, he is also, as one cannot tell what is going on back there. Chairman von Oven moved, Commissioner Goff seconded that the Chanhassen Board of Appeals and Adjustments approves a five-foot structure side yard setback variance with an additional 18-inch encroachment for the eaves subject to the to the conditions of approval, and adopts the Findings of Fact and Decision. All voted in favor and the motion carried unanimously with a vote of 6 to 0. 406 Planning Commission Minutes – April 19, 2022 3 PUBLIC HEARING: 855 PLEASANT VIEW ROAD: CONSIDER A REQUEST FOR SUBDIVISION REVIEW FOR TWO LOTS WITH VARIANCES FOR THE USE OF A PRIVATE STREET AND A NECK LOT Senior Planner Generous gave a staff report, noting this is a two-lot subdivision and the proposed development is consistent with the guided use of residential low-density. The proposed subdivision creates two single-family lots, the first adjacent to Pleasant View Road and the second is the neck lot. There is a wetland located on the southern part of the property. Staff directed the Applicant to come in from one access point via a private street and the only public improvement would be the extension of a water line across Pleasant View Road and the installation of a fire hydrant. Water Resources Engineer Seidl said regarding drainage and grading on the site, the project area generally slopes down from the northwest with some relatively steep slopes on the site. Stormwater runoff is conveyed through properties on the east to Fox Path Road where it is collected by public infrastructure and outlets into Lotus Lake. Mr. Seidl shared the Watershed District rules including the abstraction rule, water quality rule, and peak discharge rate rule and spoke about potential impacts or adverse effects for the development and for the Applicant to design around those potential impacts. He received comments from two residents who are concerned about the project as they are directly downstream. Mr. Generous stated Staff believes the Applicant meets all these findings and recommends approval of the subdivision with the variances for the private street and neck lot subject to the conditions of approval of the Staff report. Matt Pavek, Civil Engineer on the project, shared they are almost through the preliminary design phase, everything is sized, and the final design will meet all the requirements. They are working with the Watershed District as they have rather robust requirements, as well. Todd Simning, working with the Applicant, shared that historically there were two houses on the property which discharged stormwater offsite. That definitely did have an impact to the downstream neighbors. He noted they are upsizing the basins to be sure that there is not an issue for any parties. Chairman von Oven opened the public hearing. Ed Szalapski, 850 Pleasant View Road, welcomes the development and thinks the houses will be a great improvement to the neighborhood. He thanked Mr. Generous for asking the Applicant to put in a single private road rather than three driveways. Mr. Szalapski was looking through plans for utilities noting his driveway is right across and would like a guarantee that someone without a four-wheel drive truck will be able to get in and out of there. He noted he bought his property in 1994 and in looking at the original plats he has a little strip of land on the south side of Pleasant View Road across from his property. He believes it is within the City right-of-way but the City is not using it; his understanding is that it is still his property and he wants to make sure the new development will not encroach on that. He worries about subtracting that land from his property when it comes to hardcover calculations and things like that. 407 Planning Commission Minutes – April 19, 2022 4 Mr. Generous noted Staff disagrees with Mr. Szalapski’s analysis that he owns that property as it was shown as platted right-of-way which puts it in the City’s ownership. Chairman von Oven closed the public hearing. Commissioner Johnson moved, Commissioner Schwartz seconded that the Chanhassen Planning Commission recommends City Council approve a request for subdivision review for two lots with variances for the use of a private street and a neck lot on property located at 855 Pleasant View Road subject to the conditions of the staff report, and adopts the Findings of Fact and Recommendation. All voted in favor and the motion carried unanimously with a vote of 6 to 0. PUBLIC HEARING: 775 AND 731 W. 96TH STREET (ERHART FARM): CONSIDER A REQUEST FOR REZONING AND PRELIMINARY PLAT TO ADD TWO LOTS TO THE APPROVED PRELIMINARY PLAT FOR THE ERHART FARM DEVELOPMENT WITH A VARIANCE FROM THE TREE REPLACEMENT REQUIREMENT Mr. Generous noted this is an amendment to a preliminary plat that was previously approved. The Applicant is adding 1.08 acres to the development. As part of this, they must rezone the property from agricultural to single-family residential which is consistent with the Comprehensive Plan. Mr. Generous noted the only revision is because of a small area on the south end. He shared about tree preservation and landscaping noting the variance from the tree replacement requirement is for using less than 2.5 inch tree stock and certified nursery tree stock. Staff recommends approval. Mr. Henricksen gave an overview of grading and drainage, noting the changes are not substantial. The site is proposed to be mostly mass graded and tree clearing has already commenced. Mr. Henricksen spoke about public sanitary and water mains, as well as stormwater. Dan Blake, Black Cherry Development, spoke about Outlot A, maintenance, and the tree question on the west side of the street. The Applicant thinks trees along the west side would have the most visible benefit to the public and neighborhood. They would agree to relocating or replacing those trees in the future. Chairman von Oven opened the public hearing. Chairman von Oven closed the public hearing. Commissioner Schwartz moved, Commissioner Soller seconded that the Chanhassen Planning Commission recommends City Council approve the amended preliminary plat with a variance for the tree replacement requirements subject to the conditions of the staff report, amend the rezoning to include the additional parcel, and adopts the Findings of Fact and Recommendation. All voted in favor and the motion carried unanimously with a vote of 6 to 0. 408 Planning Commission Minutes – April 19, 2022 5 PUBLIC HEARING: CONSIDER A CODE AMENDMENT REGULATING THE OUTDOOR STORAGE OF WATERCRAFT ON RESIDENTIAL PROPERTIES Mr. Young-Walters gave the staff report on the item, noting the item will go before City Council on May 9, 2022. The issue is the desirability of amending City Code to permit the seasonal storage of watercraft in residential driveways. The existing ordinance restricts watercraft storage to the side and rear yards of properties. Because of side yards on lots it is not always possible for residents to put their boats in that location and additionally when individuals violate the ordinance it is difficult to enforce due to the mobile nature of trailers and watercrafts which can create frustration. The proposed solution is to allow one watercraft trailer and associated watercraft to be stored on driveways between April 1 and October 1. Homeowners associations would still retain the ability to establish standards for their neighborhoods. Staff believes this would make it easier to enforce and believes it strikes a balance between allowing residents reasonable use of their property and preserving the character of the City’s neighborhoods. Mr. Young-Walters showed exhibits and examples on screen. He shared about resident feedback, noting 10 emails were received with six in opposition to the proposed changes and four in support. All comments were forwarded to the Planning Commissioners. The Commissioners asked clarifying questions regarding the potential amendment and discussed different scenarios, driveway lengths, sight lines, RV’s and other storage uses versus boats, and safety. Chairman von Oven opened the public hearing. Bryce Marsh stores his boat at his cabin in the summer and in his garage in the winter. He has been cited multiple times with his boat in the driveway bringing it back from the cabin or pulling it out of the garage. He advocates for adding RV’s. Nick Pekarek, 202 Chan View, is an outdoorsman and needs access to the boat until the water freezes up. He noted to park a boat alongside his garage, he only has a 5-6 foot space available. He is asking for longer dates in the fall and does not understand why he cannot park a boat in the driveway. Chairman von Oven closed the public hearing. Chair von Oven said there is no denying that the City is somewhat divided on this issue. There is a desire to allow people to use their property for the hobbies they have and he was both surprised and disappointed when it did not pass the City Council two years ago. He agrees that the date is wrong and would like to amend it to at least November 1 if not December 1. Commissioner Noyes thinks the percentage of outdoor stored boats goes down after Labor Day. Commissioner Schwartz asked why the language pertaining to RV’s and other types of vehicles was removed from the proposed language. 409 Planning Commission Minutes – April 19, 2022 6 Mr. Young-Walters replied the City Council directed Staff to explore watercraft and watercraft trailers only. Chairman von Oven moved, Commissioner Noyes seconded that the Chanhassen Planning Commission recommends the City Council approve the proposed amendment to Sections 1- 2 and 20-909 of the Chanhassen City Code concerning the outdoor storage of watercraft, amended with the start date of April 1 and end date of December 1. All voted and the motion carried with a vote of 5 to 1.
