Background
The plat consists of subdividing approximately 5 acres into a subdivision with a total of 13 dwelling units and one outlot for ponding. Originally 1`5 lots were envisioned but two of the lots will instead be platted as Outlot A to meet storm ponding for this development. If a more regional ponding solution is developed in the next future it is possible that Outlot A could be re-platted for an additional two lots. 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 will be utilized to establish the minimum standards for each of these issues. The flexibility provided by the DF zoning has formed the basis of the Harpers Street Development Guide Plan and the many plats that have followed.
The proposed plat is located along the 127th Avenue alignment, west of Harpers Street NE.
Engineering Items
Developer installed improvements shall include construction of all streets within the plat (127th Avenue and Guadalcanal Street) 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 2014 rate for Sanitary Sewer District 6-5 is $5,205 per upland acre. There are 5.01 acres in the plat for a 2014 cost of $26,077.
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 $1,314 per lot (2014 rate). The plat contains 13 lots and will have a responsibility of $17,082.
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 approved the project.
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 13 lots (with four corner lots) would normally plant 34 trees. One additional tree will be required to be planted within the plat.
The final plat is consistent with the approved preliminary plat, Resolution No. 13-108.
Recommendation
By motion, approve the Resolution.
