Overview Tradition Development (a/k/a SBF Development Corp.) representatives are requesting approval of the Spirit of Brandtjen Farm (SBF) 23rd Addition final plat, which consists of 47 detached townhouse lots, five common area HOA lots, and four outlots located south of 160th Street (CSAH 46), north of 161st Street, and east of Eagleview Drive. This is the second phase of the SBF 21st Addition preliminary plat of 43 attached townhouse lots and 99 detached townhome lots approved by the City Council on April 1, 2019. The SBF 21st Addition final plat of 43 attached townhome lots and 52 detached townhome lots was approved by the City Council on June 17, 2019. The layout of the SBF 21st Addition final plat is consistent with the approved preliminary plat. In conjunction with the SBF 21st Addition final plat, a no parking resolution is required consistent with the street designs approved with the SBF PUD. Primary Issue to Consider • Why is an access easement agreement included with this final plat? An easement is needed for the publicly accessible, privately maintained sidewalks proposed within Outlot B, which will be owned by the SBF HOA.

Daniel Licht, AICP DATE: 20 August 2020 RE: Lakeville – Spirit of Brandtjen Farm; 23rdAddition Final Plat TPC FILE: 135.01 BACKGROUND SBF Development Corporation has submitted application to final plat Spirit of Brandtjen Farm 23rd Addition. The final plat consists of 47 detached townhouse dwelling units, 4 outlots, and public right-of-way to be developed upon Outlot F, SBF 21st Addition, which is located east of Eagleview Drive and north of 161st Street. The subject site is zoned PUD, Planned Unit Development District as approved by the City Council on 20 June 2005. The PUD Development Stage Plan and preliminary plat for SBF 21st Addition was approved by the City Council on 1 April 2019. Exhibits: A. Site Location Map B. Approved Preliminary Plat C. Landscape Plan (3 sheets) D. Final Plat (3 sheets) ANALYSIS SBF Land Use Plan. The SBF Master Land Use Plan (Page 3.4 of the SBF PUD Booklet) designates development of the subject site for Residential Village Center abutting Eagleview Drive with Medium Density Residential uses at 6 to 8 dwelling units per acre extending east to the regional greenway corridor trail. The overall density of the preliminary plat is 6.75 dwelling units per acre. The area of Outlot F, SBF 21st Addition is 8.6 acres. The proposed density of the 2 47 detached townhouses proposed within the SBF 23rd Addition Final Plat is 5.47 dwelling units per acre. As approved with the PUD Development Stage Plan for SBF 21st Addition, the proposed detached townhouse dwellings within the final plat provide a transitional land use between Eagleview Drive and the public elementary school to the east consistent with the SBF Land Use Plan. Lot Area. The PUD Development Stage Plan for the subject site included allowance for 4,762 square feet of lot area per dwelling unit. The proposed number of dwelling units within the subject site has been approved based on the key flexibilities established for the SBF PUD District for density transfer. Allowance of the lot area per dwelling unit for the proposed development is also appropriate in the context of an acceptable site plan that provides for a unique neighborhood character. Setbacks. The table below indicates the required setbacks for the proposed development as established by the PUD Development Stage Plan approval to provide for building forward streetscape character and to allow the detached townhouse buildings to be shifted to one side of the unit lot line. This offset of the detached townhouse building within the unit lot allows opportunity for outdoor living areas to the side the building within a larger side yard, which is a creative and efficient use of the area between structures. Yard Structure Min. Setback Front Building 15ft. Garage Door NA Side-Corner Building 15ft. Rear Building NA Garage Door 25ft. Between Buildings Detached TH Sidewall to sidewall 14ft. Sidewall to unenclosed deck or pergola 7ft. ROW/Buildings Guest parking 15ft. Streets. The final plat provides for Duvane Way off of 161st Street as a public street within a 52 foot wide right-of-way and with a 28 foot wide street section consistent with the design for SC.3 established by the SBF PUD Booklet. Parking will be restricted to one side of Duvane Way at the time of final plat approval. The construction plan for the proposed public street is to be subject to review and approval of the City Engineer. Private Drives. The final plat includes 4 private drives within outlots for rear loaded access to the attached garage for each detached townhouse. The section design for the private drives are 20 feet in width and have concrete curb on each side. The proposed private drive section design is consistent with the standards incorporated as part of the SBF PUD Booklet. The proposed private drives are to be posted as fire lanes with no parking allowed. The construction plans for the proposed private drives are to be subject to review and approval of the City Engineer. 3 Trails/Sidewalks. A trail is currently under construction along the south side of 160th Street (CSAH 46) from Eagleview Drive to Diamond Path abutting the subject site. There is an existing five-foot wide sidewalk abutting the subject site on the north side of 161st Street. The submitted plans indicate that five-foot wide concrete sidewalks will be constructed both sides of Duvane Way at the front of the detached townhouse dwellings (but not including on the north side not of Duvane Way between Lots 9 and 10, Block 1). The site plan also provides for 2 sidewalks within Outlot B at the front of the row townhomes within Blocks 3 and 4. Construction plans for the proposed sidewalks are to be subject to review and approval of the City Engineer. Landscaping. A landscape plan has been submitted for the proposed final plat that includes street boulevards, private drives, common open spaces, and the typical foundation plantings for the townhouse and detached townhouse dwellings. A landscape buffer yard abutting 160th Street (CSAH 46) consistent with previous phases of SBF is also illustrated on the landscape plan, with the plantings installed on the interior side of a 10 foot high berm. The types and sizes of proposed plantings comply with Section 11-21-9.C.1 of the Zoning Ordinance. The developer must provide cost estimates for the plantings to be installed to verify compliance with the requirements of Section 11-58-21.J.1 of the Zoning Ordinance. Park Dedication. The final plat for SBF 23rd Addition does not include dedication of land to the City for public parks in accordance with the 2015 Parks, Trails, and Open Space Plan. Park dedication requirements are to be satisfied by payment of a cash fee in lieu of land at the time of final plat approval based on the provisions of the SBF Master PUD Agreement. Easements. Section 10-4-4 of the Subdivision Ordinance requires 10-foot wide drainage and utility easements at the perimeter of the base lots. The final plat provides for dedication of drainage and utility easements over all of the base lots as well as over all of the outlots. The proposed drainage and utility easements comply with the Subdivision Ordinance. All drainage and utility easements are subject to review and approval of the City Engineer. Grading. The plans with the final plat application include grading, drainage, and erosion control plans. All grading plans are subject to review and approval by the City Engineer. Utilities. The subject site is included within the current MUSA. Plans for construction of sewer and water utilities to the detached townhomes within the proposed final plat have been submitted. All utility plans are subject to review and approval of the City Engineer. Outlots. The preliminary plat includes the following outlots: Outlots Purpose Ownership A, C, D Private drive HOA B Publicly accessible/privately maintained sidewalk HOA 4 Homeowners Association. Documents including SBF 23rd Addition as part of the SBF Master Homeowners Association and establishing separate homeowners association provisions for the detached townhomes are required. All homeowners association documents are subject to review and approval by the City Attorney. Development Agreement. Section 10-5-1.A of the Subdivision Ordinance requires the developer to provide construction and warranty securities for the public improvements within the final plat that are to be outlined within a development agreement. The development agreement is to be drafted by the City Attorney and executed by the applicant prior to City Council consideration of the final plat. Dakota County.

DDRRAAIINNAAGGEE AANNDD GGRRAADDIINNGG BBAACCKKGGRROOUUNNDD Spirit of Brandtjen Farm (SBF) is a planned unit development of which development began in 2005. The proposed development encompasses nearly all of the north half of Section 1, Township 114, Range 20 and a substantial portion of the south half of said section. The initial stormwater modeling and drainage plan for SBF, located on the south half of Section 1, was prepared by Westwood Professional Services. The original design consisted of a main basin, Spirit, surrounded by six National Urban Runoff Program (NURP) basins. The Spirit basin design did not include a gravity outlet other than infiltration. A system of pumps was incorporated into the design to serve three functions: 1) Irrigation supply, 2) Recirculation for water features, and 3) Drawdown, if needed. During 2008, a decision was made to not construct the recirculation features. As a result, the proposed pumping station was not constructed, however, the pump station draw intake line was. As development has continued, Spirit basin appears to have adequately infiltrated all runoff from the development without the presence of the pumping system. A gravel processing area has been in operation on the north half of Section 1 in excess of forty years. As part of gravel operations years ago, a series of basins was constructed as wash basins for sand processing. The operational need for these basins ended approximately in 2013 and a reclamation plan was prepared for the gravel processing area. As part of the reclamation plan, the largest basin was measured and quantified, and incorporated into the reclamation plan with intended use as a stormwater management basin. The basin is referred to as Nordeast Basin. PPRROOPPOOSSEEDD SSTTOORRMMWWAATTEERR MMAANNAAGGEEMMEENNTT PPLLAANN SBF 23rd Addition is located within the North Creek drainage district as identified in the City’s Water Resources Management Plan.

The proposed system utilizes the existing Nordeast Basin for flood storage and infiltration, having peripheral National Urban Runoff Protection (NURP) and stormwater collection systems. The pretreatment NURP basins are multi-celled. The stormwater management system to serve SBF 23rd Addition was constructed with development of SBF 18th Addition and SBF Commercial 2nd Addition. A National Pollution Discharge Elimination System General Stormwater Permit for construction activity is required by the Minnesota Pollution Control Agency for areas exceeding one acre being disturbed by grading. A copy of the Notice of Stormwater Permit Coverage must be submitted to the City upon receipt from the MPCA. SSTTOORRMM SSEEWWEERR Development of SBF 23rd Addition includes the construction of a public and private storm sewer system. Storm sewer will be installed to collect and convey stormwater runoff generated from the streets and open space within the development. The storm sewer will convey the runoff to the stormwater management basins located downstream of the development. The constructed public storm sewer shall be located within public right-of-way and/or public drainage and utility easements. The Trunk Storm Sewer Area Charge will not be collected for SBF 23rd Addition as the entire area of the plant drains directly to Nordeast. Final locations and sizes of all storm sewer facilities will be reviewed by City staff with the final construction plans.
