Planning Commission
The Planning Commission voted unanimously to recommend approval of the Preliminary Plat and CUP. There were some comments from adjacent property owners related to house prices and regional storm ponding.
Background
The North East 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.
The land was originally preliminary platted as a part of a larger plat known as Harpers Woods. This area was never final platted due to a turn in the economy.
The preliminary plat proposal consists of subdividing approximately 5 acres into a subdivision with a total of 15 dwelling units. This application proposes single-family homes. Park Dedication will be required as part of the platting.
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 flexibility provided by the DF zoning forms the basis of the Harpers Street Development Guide Plan.
The proposed plat is located along the 127th Avenue alignment, west of Harpers Street NE.
Neighborhood Description
In summary, Marquest Meadows North is proposed to contain the following:
15- Single-Family Lots
The single-family product on 80 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 $225,000-$300,000+. Shadetree Builders is planning to be the primary builder within this development, but may open the development to other builders.
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 135 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, streets with concrete curb and gutter, 6 foot concrete sidewalks along east side of Guadalcanal Street and north side of 127th Avenue, 8 foot bituminous trail on the west side of Harpers 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 upland acreage. The 2013 rate for Sanitary Sewer District 6-5 is $5,179 per upland acre.
The developer has responsibility for financial participation in the Plat's share of the cost of off-site improvements required by Anoka County on 125th Avenue NE at Harpers Street. 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 following:
The developer has responsibility for financial participation in 125th Avenue NE improvements associated with this development. This includes, but is not limited to, intersection improvements, traffic signal installations, and roadway widening improvements. Anoka County will specify required improvements in their review. 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 to be $1,307 per lot (2013 rate). The plat, if it ultimately contains 15 lots, would have a responsibility of $19,605 if platted in 2013.
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 for future connections 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.
Developer will need to create a temporary storm pond (southeast corner of the plat) that will need to be maintained and contained within an Outlot until a regional storm sewer system is constructed. The developer of the Marquest Meadows North plat will also have the responsibility to pay for its portion of the future costs of the Harpers Street Area regional storm sewer system project.
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.
Coon Creek Watershed District (CCWD) has this plat scheduled to appear before their board on June 10, 2013.
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 35 (seven trees per acre) to be replaced. The 15 lots (with four corner lots) would normally plant 34 trees. One additional tree will be required to be planted within the plat.
