Planning Commission
The Planning Commission voted unanimously to approve the preliminary plat. There were no comments at the public hearing.
Background
The Northeast Area Plan Amendment, approved in October of 2002, created a land use designation of LDR (Low Density Residential) for the area included within this plat. The Harpers Street Development Guide Plan was adopted by the City Council in mid 2005. This parcel was once part of a larger preliminary plat that was never completed however at that time the parcel was rezoned to DF (Development Flex) as part of that process.
The current preliminary plat proposal consists of subdividing approximately 5.3 acres into a subdivision with a total of eight (8) dwelling units. This application proposes single-family homes consistent with the DF zoning and LDR land use designation.
Because the developer is proposing different housing styles with different design issues, platting requirements, lot sizes, markets and price ranges, the existing DF (Development Flex) zoning is proposed to establish the minimum standards for each of these areas.
The proposed plat is located along the 128th Lane alignment, west of Harpers Street NE. As part of the platting Park Dedication will be required for the eight (8) lots that are created.
Neighborhood Description
In summary, Deer Pond is proposed to contain the following:
8- Single-Family Lots
The single-family product on 72-100 foot wide lots will be enhanced with exterior architectural details. The homes will include brick, stone, varying gables and hip rooflines. The floor plans would provide a minimum square footage of 1,500 square feet of finished area above grade for a split entry or modified two-story and a minimum of 1,400 square feet above grade for a rambler style home. The estimated price range is $400,000-$450,000+.
All single-family units are proposed to be constructed with a 25-foot front yard setback and 30-rear yard setback. The lots will generally be around 80 feet wide and 130 feet deep.
Engineering Items
Developer installed improvements shall include construction of all streets within the plat including lateral sanitary sewer and water main with services, storm drainage improvements, storm water management and water quality treatment infrastructure, bituminous streets with concrete curb and gutter, 6 foot concrete sidewalks along south side of 128th Lane and east side of Coral Sea Street, streetlights, mailboxes, traffic control signs, street signs, and all appurtenant items. Plans and specifications must be approved by the City prior to start of construction.
Trunk sanitary sewer area charges become due with platting for 4.69 acres of upland. The 2017 rate for Sanitary Sewer District 6-5 is $5,917 per upland acre for a total due of $27,751 if platted in 2017. This amount is due prior to the release of mylars for recording at the county.
The developer has responsibility for the City’s financial participation in 125th Avenue NE improvements associated with the traffic that is generated from this development. This includes, but is not limited to, intersection improvements, traffic signal installations, and roadway widening improvements. The City has calculated the development potential of all of the developable property lying north of 125th Avenue and within the current development schedule provided by the 2005 MUSA and has determined the per lot cost associated for the improvements. The 2017 rate of $1,494 will apply to this plat for the 8 lots for a total of $11,952, if platted in 2017. This amount is due prior to release of mylars for recording at the county.
All local public streets typically require dedication of 60 feet of right-of-way and shall be constructed to 29 feet back to back of width.
Street and utility extensions are required to the edges of the plat to connection to the adjacent parcels.
Standard utility and drainage easements must be dedicated along all lot lines and over areas of wetlands, wetland mitigation, infiltration trenches, drainage swales, and storm water management ponds. The Developer is to provide access for inspection and maintenance of storm water management infrastructure. Restrictions will be placed on lot lines as needed to limit fences and landscaping to insure access. Developer to verify normal ground water elevation in ponds. If the “Normal Ground Water Elevation” does not match the “Normal Water Elevation” that the 10:1 safety bench is designed at, provide a dense vegetative buffer strip between the two elevations. Developer shall submit a buffer strip seed mix design for review. All pond slopes shall be 4:1 except below Normal Ground Water Elevation, which can be 3:1.
Each lot shall have a minimum rear yard area behind each structure of a minimum of 20 feet from the structure at a maximum grade of 5%.
Development requires a National Pollutant Discharge Elimination System (NPDES) Phase II Permit from Minnesota Pollution Control Agency (MPCA).
Construction contract documents shall include a grading, erosion protection, sediment control, development, utilities, roadway, and storm drainage plans. Plans shall detail tree preservation, erosion protection, sediment control, proposed grading contours, utilities, roadway geometrics, storm drainage, storm water quality management, custom lot-grading, structure type, and structure elevation information. Additional information is required on adjacent parcels that indicate existing drainage patterns are being addressed. The development plan shall indicate all structures will be protected from flooding. Supporting geotechnical investigation report, soil boring logs and hydrology report shall be included in the submittal for City review and approval.
A Coon Creek Watershed District (CCWD) permit is required prior to any plan approval by the City.
As-built surveys shall be required to verify structure elevations, custom grading requirements, and final lot grading elevations.
The plat contains a significant number of trees that will be removed as part of the grading for lots and storm water improvements. The City’s tree replacement requirements would require 38 trees (eight trees per acre) (4.8 disturbed acres) to be replaced. The Developer is required to plant three trees per lot for the overall preliminary plat which will account for 24 of the replacement trees. A landscape plan for the remaining 14 trees must be presented to the Planning Department prior to release of mylars for recording at Anoka County, or the Developer can make a cash payment of $4,200 ($300 per tree) to the City’s reforestation fund.
