SUMMARY Applicant: Prestwick, LLC (Scott Johnson) Comp. Guide Plan Designation: LDR – Low Density Residential Current Zoning: R1-PUD Low Density Residential with the Prestwick Place Planned Unit Development Gross Area: 59.98 Acres Net Area: 18.83 Acres (excluding future outlot phases) Lots/Units: 38 Single Family Lots Gross Density: 0.64 units/acre Net (Met Council) Density: 2.02 units/acre 2 The Planning Commission is being asked to consider a Final Plat request from Prestwick, LLC for Prestwick Place 14th Addition to allow development of 38 single-family lots. The final plat is necessary to facilitate subdivision of the property into individual residential lots, outlots, and public streets. Staff finds the application consistent with the Prestwick Place 13th Addition Preliminary Plat (which covers this area) and recommends approval of this application subject to the conditions listed above. BACKGROUND The Planning Commission reviewed a preliminary plat and planned united development (PUD) master development plan for Prestwick Place 13th Addition to allow 191 lots on 73 acres at its July 26, 2016 meeting. The City Council approved the preliminary plat and PUD plans at a later meeting based on the recommendation of the Planning Commission with a slight reduction in the overall number of lots to 186. The applicant subsequently submitted a final plat for the first phase of development within the plat area, which was approved on September 6, 2017. The first phase was located along Akron Avenue in the far eastern portion of the preliminary plat area. The applicant is now proposing to develop the second phase of the project, but rather than continuing to plat lots from east to the west, the applicant is proposing to shift to the far western portion of the project area for the second phase. The primary reason for the revised phasing is to be able to construct a model home closer to Connemara Trail and provide more direct access into the development from Connemara Trail. The proposed final plat represents the second development phase within the Prestwick 13th preliminary plat area, and would create 38 single-family lots clustered at the far western edge of the development. In addition to the residential lots, the applicant will be dedicating right-of-way for an extension of Ailesbury Avenue to serve the subdivision, along with a small segment of 140 Street that will connect into the adjacent Bloomfield neighborhood and a new road to be called Ashford Path in the northern portion of the plat. The Prestwick Place 14th Addition final plat will also create three larger outlots reserved for future project phases. ISSUE ANALYSIS Legal Authority. The final plat application is Quasi-Judicial because the City has a set of standards and requirements for reviewing this type of application that is described in detail below. Generally, if the final plat meets the ordinance requirements it must be approved. Land Use and Zoning. The proposed 38 lot single family development is consistent with the land use and zoning classifications for the project area. The subject property is guided LDR – Low Density Residential and zoned R-1, Low Density Residential with the Prestwick Place 13th Addition Planned Unit Development (PUD). As a result, the property is subject to all the standards of the R-1, Low Density Residential zoning districts as well as the standards for detached single family units contained in the PUD. The Prestwick PUD included several deviations from the base R-1 zoning; the most notable include the following: 1. Section 11-2-15 F. Single Family Detached Dwelling Garage Requirements: The home designs do not need to include an option for a three garage stall. 2. Section 11-4-5 F. 1. R-1 Minimum Lot Area: The minimum lot area shall be 8,600 square feet for interior lots and 10,200 square feet for corner lots. 3. Section 11-4-5 F. 2. R-1 Minimum Lot Width: The minimum lot width shall be 65 feet for interior lots and 80 feet for corner lots. 4. Section 11-4-5 F. 4. R-1 Minimum Front Yard Setback: The minimum front yard setback shall be 25 feet. 5. Section 11-4-5 F. 5. R-1 Minimum Side Yard Setback: The minimum side yard setback shall be 7.5 feet. 6. Section 11-4-5 F. 9. R-1 Maximum Lot Coverage: The maximum lot coverage shall be forty percent (40%) for lots less than 9,750 square feet in size and thirty-five percent (35%) for greater 3 than 9,750 square feet. Overall, the final plat conforms to the R-1 district standards and Prestwick PUD requirements, with the smallest lot within this project phase at a little over 9,000 square feet and the width of the narrowest lot at 65 feet. Many of the other standards are addressed at the building permit stage when an individual site survey is reviewed by the City. Final Plat. Standards for reviewing subdivision requests are detailed in Title 12 of the Rosemount City Code. This section of the Code outlines the two-step Preliminary and Final Plat process for land subdivision. In this case, the preliminary plat was approved on September 6, 2016 consisting of 186 single family lots. The current application proposes to plat 38 single family lots for Prestwick Place 14th Addition and to dedicate the easements necessary to construct the storm water retention area within the overall development area. The developer has made some very minor modifications to the preliminary plat in order to accommodate wider easements over certain lots as required by the City Engineer. Taking these adjustments into account, the Prestwick Place 14th Addition Final Plat is consistent with the approved Prestwick Place 13th Addition Preliminary Plat. In conjunction with the final plat request, the developer is also proposing to vacate existing drainage and utility easements that were provided over this area. The existing blanket easement will then be replaced with easements as delineated on the final plat. The Planning Commission is not required to take action on the easement vacation request; easement vacation is a Council action. However, the map showing existing easements to be vacated is provided for information. Streets & Access. The final plat will dedicate an extension of Ailesbury Avenue as it heads north of Connemara trail. Access to the 38 lots will occur from this intersection until such time that other internal roads are connected to future project phases. The proposed final plat also includes a secondary road connection to 140th Street West from the neighborhood to the west. A short segment of 140th Street West was constructed with the Bloomfield 7th Addition plat, and this right-of-way was platted up to the property line adjacent to the applicant’s site. There is a small segment of the road that will need to be constructed within the adjacent plat (roughly 20 feet) in order to make this connection. The plat will also include approximately one-third of Ashford Path in the northern part of the subdivision running parallel with the railroad right-of-way in this area. The typical street design for this overall subdivision is a 32-foot-wide street with a sidewalk installed on one side of the street. This typical design meets the City’s standards for a street that allows parking on both sides of the street. Based on a condition added to the preliminary plat approval, the plans for Ashford Path and Ailesbury Avenue include sidewalks on both sides of this street. The applicant is working with City on a slight modification to the overall construction plans for this project phase in order to ensure that Ailesbury Avenue property aligns with the intersection of Connemara Trail. The City Engineer has pointed out that the necessary alignment can be accomplished within the proposed right-of-way; therefore, no plat modifications are necessary to accomplish the proper connection. 4 Landscape and Berming. The landscape plans have been updated to reflect the revised phasing for the project and indicate that there will be one tree planted on each interior lot, and two trees on every corner lot as required by the landscape ordinance. With thirty-three interior lots and five corner lots, the developer is required to plant a minimum of forty-three trees on private lots within the final plat. In addition to the trees required by ordinance, the developer is also proposing to install an additional 10 trees along the Connemara Trail right-of-way in order to comply with a condition of preliminary plat approval for buffering and screening along this road. Because there are no lots that back directly on to Connemara Trail (the only homes that front Connemara are side lots at the entrance into the plat) a berm is not needed to comply with the preliminary plat requirements. The majority of the Connemara Trail frontage is used for storm water ponding. With these revisions, the updated plans are in conformance with the previous conditions of approval and exceed the minimum requirements of the Zoning Ordinance for landscaping. Grading and Storm Water Management. The grading plan for Prestwick Place 13th Addition was previously updated to reflect the changes in phasing throughout the development and to expand the amount of storm water retention in the southern portion of the site. In addition to the larger southern pond, the prosed grading along the northern portion of the site (adjacent to the railroad right-of-way) was revised to direct more storm water to the west and south. The 14th Addition includes the larger storm water retention area in the southern portion of the plat along Connemara Trail that will collect storm water runoff from individual lots as well as the public roads within the subdivision. One of the preliminary plat conditions noted that this particular pond should be dedicated within an outlot; however, after further reviewing the proposed grading around the pond, Staff is recommending that the pond remain under private control subject to a drainage and utility easement. Staff has also worked with the developer to configure the lots around the pond so that maintenance of the slopes adjacent to the pond will be owned and maintained by the adjacent homeowners. Please note that a portion of the pond will be replatted to match up with individual lots in the adjacent project phase. Parks and Open Space. The Parks and Recreation Director has previously reviewed the Prestwick Place 13th Preliminary Plat and noted that no additional land is anticipated to be dedicated within the subdivision for park purposes. There is an existing City Park located in the middle portion of the overall PUD area on the south side of Connemara Trail approved during the original Prestwick Place Preliminary Plat approval in 2007. The existing park (Ailesbury Park) will serve the entire Prestwick Place neighborhood located west of Akron Avenue. Staff is recommending that the developer pay cash in lieu of land dedication consistent with the City’s park dedication requirements. The required cash payment amount is documented on the attached memorandum from the Parks Director. For the 14th Addition final plat, the developer will be required to pay a fee in lieu of land dedication of $129,200 for the 38 proposed lots. Sidewalks, Trails and Pathway. Access to the City’s trail system is provided by trails that have been constructed along Connemara Trail and Akron Avenue. Within the subdivision, pedestrian access will be provided by a sidewalk on one side of every street, including all cul-de-sacs, and the sidewalks along both sides of Ashford Path and Ailesbury Avenue. 5 Engineering Comments. The City’s project engineer has provided comments in the attached memorandum dated June 27, 2017. Some of the highlights from this memorandum are as follows:  Agreements between the holders of easements for transmission facilities within the site and the developer are required.  The City engineer has requested minor revisions to the stormwater plan to better comply with the City’s standards.  A temporary cul-de-sac is needed at the end of Ashford Path to provide room for larger vehicles to turn around within the subdivision.  The developer will be responsible for various fees associated with the development and existing cost-sharing agreements related to the construction of Connemara Trail and Akron Avenue. As a condition of approval, the developer will need to abide by the conditions and standards within the City Engineer’s Memorandum. CONCLUSION AND RECOMMENDATION Staff recommends approval of the Final Plat for Prestwick Place 14th Addition creating 38 single family lots. This recommendation is based on the information submitted by the applicant, findings made in this report and the conditions detailed in the attached resolutions.

The following review comments were generated from the following documents included in the submittal: Grading Plan Prestwick Place 14th Addition Final Plat Stormwater Management Plan and Calculations Geotechnical Evaluation GENERAL COMMENTS: 1.The development fees below are estimated based on the current Schedule of Rates and Fees. These fees are due with the final plat and subdivision agreement. GIS Fees: $60/unit Sanitary Sewer Trunk Charge: $1075/acre Watermain Trunk Charge: $6500/acre Storm Sewer Trunk Charge: $6865/ net developable acre 2.Per the existing Joint Development and Cost Sharing Agreement, the developer is responsible for the costs of adjacent roadways. These costs are as follows: Prestwick Cost Share Spreadsheet: G:\ENGPROJ\431\Prestwick Place Cost Share Tabulation - 2017.xlsm The developer is responsible for costs associated with upgrading Akron Avenue. This cost is $278.40/acre. The developer is responsible for costs associated with the recent extension of Connemara Trail between Bloomfield and Akron Avenue. This cost is estimated at $12,643.12/acre. 3.Improvements are proposed within the Northern Natural Gas pipeline easement. Prior to construction, an agreement will need to be executed with Northern Natural Gas allowing the proposed street and utility crossings and grading. A copy of the agreement shall be submitted to the City. 4.A temporary cul-de-sac will be required at the phase line past Block 1, Lot 14 and Block 2, Lot 10. The cul-de-sac should have a 45’ radius with bituminous curb. 5.The developer is required to obtain a NPDES Construction Stormwater Permit and provide a copy of the approved SWPPP to the City prior to the start of any construction activity. STORMWATER COMMENTS: 6.All reginal basins should have outlet pipes with control structures containing a weir wall set at the 100-yr, 24-hr rainfall event and an orifice with a sluice gate set at the NWL. Orifice should be sized to allow 0.05 cfs/acre of drainage area when the basin is at the HWL. 7.Lining of NURP ponding areas is not required by the City; however, the developer may want to consider as ponding areas will likely not maintain vegetation below the NWL. 8.Storm sewer inlets are generally required every 300’. Anticipate additional inlets will be required on Ashford Path. 9.Conservation easements will be required over all ponding and infiltration areas, and shall encompass at minimum the HWL and all naturally vegetated areas. Signage for conservation easements shall be provided by the developer and an extended maintenance warranty shall be required to ensure establishment of the naturally vegetated areas. 10.Storm sewer is proposed along the side and back lot lines of many properties to convey rear yard drainage. Drainage and utility easements along these lines shall prohibit the installation of sheds to ensure that access can be provided for storm sewer maintenance. Fences are allowed but shall not restrict drainage and are required to include gates for truck access over the drainage and utility easement. Also, landscaping that will block access should be prohibited. These restrictions should be added as a restriction on the property deed. 11.The width of drainage and utility easements over all public utilities shall be verified during final design. 12.Trees are not allowed to be planted within drainage and utility easements, over the proposed storm sewer, or within a pond access location. Trees located on individual properties shall not be planted near the sanitary sewer and water service lines. Should you have any questions or comments regarding the items listed above, please contact me at 651-322-2015. MEMORANDUM To: Kim Lindquist, Community Development Director Kyle Klatt, Senior Planner Anthony Nemcek, Planner John Morast, Interim City Engineer Mitch Hatcher, Project Engineer From: Dan Schultz, Parks and Recreation Director Date: June 22, 2017 Subject: Prestwick Place – 14th Final Plat The Parks and Recreation Department recently reviewed the final plat for the Prestwick Place 14th Addition. After reviewing the plans, the Parks and Recreation Department staff has the following comments: PARKS DEDICATION The parks dedication requirement for the 38 units in the 14th addition is either 1.52 acres of land or cash in lieu of land. Because the Prestwick Place development has already dedicated land that was developed as Ailesbury Park, staff is recommending that the developer pay cash in lieu of land to fulfill their parks dedication requirement. The cash in lieu of land dedication for 38 units is $129,200 (38 units x $3,400 per unit). The cash dedication is to be paid prior to, or at the time of execution of the final plat. Please let me know if you have any questions about this memo.
