Minnesota (Builder) Comp. Guide Plan Designation: LDR – Low Density Residential Current Zoning: R1 PUD/R2 PUD – Low and Moderate Density Residential (Ardan Place Planned Unit Development) Gross Area: 26.8 Acres (Phase 2 with ROW); 52.2 Acres Overall Net Area: 24.81 Acres Lots/Units: 37 Single Family Lots/81 Townhouse Lots (118 Total Units) Gross Density: 2.26 units/acre Net (Met Council) Density: 4.06 units/acre 2 The Planning Commission is being asked to consider a request from Tamarack Land Development for approval of a final plat for Ardan Place Second Addition to allow development of 37 single-family and 81 townhouse lots. The proposed plat represents the second phase associated with the Ardan Place Planned Unit development (PUD) approved by the City in 2020. Ardan Place First Addition was approved by the City in March 2021. Staff finds the application consistent with the Ardan Place Preliminary Plat, Master PUD Development Plan, and Ardan Place First Addition Final Plat and recommends approval of application subject to the conditions detailed in the attachments and the motion above. BACKGROUND In November of 2020, the City Council approved a preliminary plat, PUD master development plan with rezoning, and zoning ordinance amendment for Ardan Place, which was comprised of 79 single-family lots and 136 townhouse units on property located approximately one-quarter mile west of Akron Avenue and along the south side of Bonaire Path. The subdivision is situated between a new elementary school site to the east, the Meadows of Bloomfield neighborhood to the west, and Union Pacific Railroad right-of-way to the south. The applicant proposed to final plat the subdivision in two phases. Phase one, Ardan Place, is the eastern portion of the property that is next to the proposed elementary school site. The second phase, Ardan Place Second Addition, will be the remaining western portion of the property. During phase one the applicant dedicated right-of-way for the internal and adjacent street system and platted two larger outlots set aside for the development of phase two, Ardan Place Second Addition. The construction plans for the subdivision have been prepared to follow the location of the two planned development stages, adhering to the mass grading plan and street layout approved with the preliminary plat. This phasing plan has worked well because it has allowed the connection between the single-family and townhouse areas to be completed with the phase one of Ardan Place and as well as the storm water plan being able to be constructed in two phases from the east with the initial final plat and then to the west with Ardan Place Second Addition. Public utilities were available to serve the first phase of Ardan Place without a connection into existing systems serving the Meadows of Bloomfield neighborhood to the west. Ardan Place Second Addition will include all necessary connections to loop the system into the existing adjacent developments. ISSUE ANALYSIS Legal Authority . This application is a Quasi-Judicial action. 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 37-lot single family and 81-unit townhouse final plat is consistent with the current land use and zoning classifications (as amended in 2020 with the preliminary plat). The subject property is guided LDR – Low Density Residential and is now split between two zoning districts: R-1PUD and R-2PUD, Low and Medium Density Residential Planned Unit Development. Both districts are considered appropriate under the land use guidance, with the R-1 area covering the northern portion of site and R-2 area following a private road south of the single-family lots. As a result of the City’s previous approvals, the property is subject to the standards of the R-1 (single-family areas) and R-2 (townhouses) zoning districts as well as the standards for the entire subdivision documented the approved PUD. Through the PUD process, the developer requested and was granted flexibility from certain requirements of the zoning ordinance; the most notable deviations are listed below. • Section 11-4-5 F. 1. R-1 Minimum Lot Area: The minimum lot area shall be 8,000 square feet (10,500 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 (75 feet for corner lots). • Section 11-4-5 F. 4. R-1 Minimum Front Yard Setback: The minimum front yard setback shall be 25 feet. • Section 11-4-5 F. 5. R-1 Minimum Side Yard Setback: The minimum side yard setback shall be 7.5 feet. • Section 11-6-3 E.10: The required tree replacement is 728 caliper inches (which is in addition to the base zoning district landscaping requirement of one tree per lot). • Section 11-4-5 F. 9. R-1 Maximum Lot Coverage: The maximum lot coverage shall be 45% for lots below 10,000 square feet and 35% for lots over 10,000 square feet. After the PUD and Preliminary Plat were approved by the City, the developer came to the realization that the typical home plans that would be offered within Ardan Place would not meet the original lot coverage requirements of 30% and 40% that were approved originally. A minor PUD amendment was approved with the Ardan Place Final Plat to change the lot coverage requirements to 35 % and 45%. 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 in November of 2020 consisting of 215 single-family and townhouse lots and various outlots. During the first phase of Ardan Place the final plat subdivided unplatted land into 42 single family lots, 55 townhouse lots, two large outlots for future development, dedicated right-of-way for all subdivision public roads and two outlots for storm water ponding and common areas around individual townhomes. Ardan Place Second Addition final plat will subdivide the two large outlots that were platted during the first phase of the project for future development into 37- single family lots, 81 townhome lots and three outlots for storm water ponding and common areas around individual townhomes. The City has also required that the street that runs through the townhome section of the subdivision remain a private road and therefore it has been platted as a separate outlot on the Final Plat. The two public streets that were constructed during the initial phase of Ardan Place will continue west to serve the single-family homes in this Second Addition. Water and Sanitary Sewer. Public utilities that serve Ardan Place and will serve Ardan Place Second Addition connect into the sanitary sewer and water lines currently located within the Bonaire Path West right-of-way. These services will follow the dedicated public street or private alignments and will be stubbed for further extensions to the west with the second addition. A small portion of the Ardan Place Second Addition sewer line will connect into the existing infrastructure in the Meadows of Bloomfield development, while the water lines will be looped into this adjacent system and back out to Bonaire Path from Autumn Path. Drainage and utility easements must be provided on the plat for those lines that run underneath the private townhouse roads. Landscaping and Berming . Prior to the approval of Ardan Place final plat in 2021 the applicant updated the tree preservation and replacement plan to save a small number of trees on the western boundary of the property. Since the western portion of the property was not a part of the first phase of the project, this was not shown in the first final plat but was shown in the remaining project plans. Ardan Place Second Addition’s landscape plan reflects off the landscape plan that was approved with the first phase. It shows the required increase in caliper inches of replacement trees and as well as the required number of trees for development within R-1 and R-2 zoning districts. The second subdivision phase includes 195 comprised of a mix of trees on individual lots and replacement 4 trees within common open space areas. At $300 per tree based on the City fee schedule the required landscaping security totals $64,350 (195 trees plus 10%). The first phase of Ardan Place included 188 trees, which was just under half of the trees planned for the entire subdivision. P arks and Open Space. Parks and Recreation staff reviewed the plans for the final plat of Ardan Place Second Addition and found them to be consistent with the preliminary and first phase final plat approval. The city is not planning on any public parks within the subdivision area, and staff is recommending that the City collect cash in-lieu of land for the 118 units. This amount totals $356,650 (37 single family units at $3,400 per unit and 81 townhouse units at $2,850). The proposed dog park that will be constructed in this phase of the project is a private open space amenity for the neighborhood and will not be controlled or maintained by the City in any manner. Sidewalks, Trails, and Pathways . The first phase of Ardan place that was approved by the City was consistent with the City’s policies for sidewalks in new subdivisions. The construction plans depicted sidewalks along on side of all public streets, including the addition of a sidewalk along Ardroe Avenue connecting the townhouse area to Bonaire Path West. The plans also included a larger, multi-purpose bituminous trail along the southern edge of the townhouse area that will connect back to the sidewalk system at the eastern edge of the subdivision and along the private street connecting the townhouse and single-family areas. This trail connection will also provide direct access to the planned dog park that will be completed in this second phase for properties further north. During the first phase of Ardan Place there was talk about extending the multi-purpose trail to the west to connect into the Meadow of Bloomfield development during the second phase of the project. After discussion among staff, it was concluded that the applicant would have to obtain approval from the neighboring development to be able to make that connection. The applicant would have to submit documentation to the City of the approval between Ardan Place and the Meadows of Bloomfield before construction of the connection. Engineering Comments. The Project Engineer has reviewed the proposed Ardan Place Second Addition Final Plat and has provided comments in the Engineer’s Memo dated January 7, 2022. Notable Comments include: the developer will need to pay for the required area charges as specified in the City’s fee schedule, some drainage and utility easements will need to be vacated before the plat can be recorded, a permanent trail easement within Outlot B, street labeled Rosemount Way must be changed to Rosecommon Way, and construction plans will need to be updated to address modification requested by the City Engineer. Development fees as detailed in the Engineer’s Memo are due with the final plat and subdivision agreement. CONCLUSION & RECOMMENDATION Staff recommends approval of the Final Plat for Ardan Place Second Addition creating 37 single-family lots and 81 townhouse lots. This recommendation is based on the information submitted by the applicant, findings made in this report, and the conditions detailed in the attached memorandums.

Documents reviewed include: • ARDAN PLACE 2nd STORM SEWER DESIGN.pdf • ARDAN PLACE 2ND CONST. PLANS 11X17.pdf Applicant should provide responses to each comment. We offer the following comments below. Greyed out comments have been addressed and comments new to this review are in red. Grading, Drainage, and Erosion Control Comments: 1. General a. Show or define access routes for maintenance purposes to Pond 2 and the infiltration basin. 2. Ponds and Wetlands a. The 100-year HWL and 10-day snowmelt elevations differ between HydroCAD and the plans for the NURP basin and infiltration basin. Modify v alues to match. b. Ensure pretreatment is provided by installing sump structures on the last road accessible storm sewer structure prior to discharging into the pond. i. Add a sump to structure STMH-1. c. Refine the outlet control structure detail for Pond 2 to include the weir elevation (as modeled in HydroCAD) and the inlet pipe elevation and size. d. Call out rip rap on the plans at the storm sewer discharge points. e. Modify the infiltration basin notes to state that the soil in the upper 12-inches to 18-inches of the basin shall be amended with MnDOT Grade 2 compost or biotic media (not topsoil) due to higher pollutant retention capability and more uniform media with less fine particles. f. Modify the outlet control structure in the SE corner of the site to comply with the City design guidelines. 3. Emergency Overflow Routes a. Label the street low point EOF. b. Label the rear yard low point EOFs for Block 2 near Rosecommon Way and Block 3. 01/03/2022 Page 2 K:\016934-000\Admin\Docs\Stormwater Management Review_01032022\Ardan Place - Minea Property Rosemount Stormwater Management Review - 01032022.docx c. Ensure all low opening elevations are 1.5-feet above the EOF elevation (see grading plan review for list of homes to revise). i. Phase 1 home on Block 3 ii. Block 16, Lot 1 Stormwater Management Plan: 1. General Storm Sewer Design a. All storm sewer shall be designed to accommodate the 10-year rainfall event. Please submit a utility plan, rational calculations, and an associated storm sewer drainage area map. i. Modify CBMH 4 area in the storm sewer calculations to match the drainage area map. 2. Water Quantity a. Per past comments provided to the developer, all site drainage shall be routed to a regional outlet control structure that connects overflows from the site to the east as shown in the City SWMP. Please show the equalizer pipe between the Phase 2 and Phase 1 infiltration basins (as mentioned in HydroCAD) that will facilitate drainage to the east for the Phase 2 portion of the site. 3. Modeling a. Modify the primary outlet pipe from Pond 2 to match the plans and outlet control structure detail. b. Include the OCS grate and EOF between Pond 2 and the infiltration basin in the model because the 10-day snowmelt flow utilizes those outlets. SWPPP: 1. Erosion Control Plan a. Call out inlet protection on all catch basins along Autumn Path and Bonaire Path. i. Add inlet protection near the rock entrances on the right hand side of the roadways. ii. Show inlet protection on the inlet south on Autumn Path. b. Show where to install the silt fence around the basins post grading. The leader should point to silt fence.
