Background
The final plat consists of subdividing approximately 109 acres into a subdivision with a total of 28 new lots and one lot for the existing home on 125th Avenue. The final plat also includes outlots for ponds, drainage, wetlands, and future development.
ENGINEERING ITEMS
The developer has responsibility to construct 125th Avenue NE intersection improvements associated with this development. Anoka County has specified required improvements in their plat review.
All local public streets require dedication of 60 feet of right-of-way and shall be constructed to 29 feet back to back of width. All streets will follow the Anoka County street name grid system.
Developer and staff will work together to identify areas of the plat where additional trees can be saved through the use of custom grading, retaining walls, and by structure design.
The property owners in this plat, together with other property owners along Lever Street have petitioned for trunk sanitary sewer, water main, and street improvements to be constructed to serve the plat. A feasibility report was prepared and presented to the City Council on June 1, 2017. The report identified assessments that each parcel on Lever Street would pay for the proposed improvements. The estimated cost for property owners of this plat are estimated at $384,846. The Blaine City Council held a public hearing and ordered improvements on July 13, 2017 (City Project No. 17-07). The Oakwood Ponds development will be responsible for paying assessments for the improvements.
It is anticipated that the city project, to install the trunk sanitary sewer and trunk water main along Lever Street NE from 125th Avenue NE to serve properties along Lever Street NE, will be Spring/Summer of 2018.
Trunk Sanitary Sewer area charges become due with platting for upland acreage (the 28 lots). The 2017 rate of $6,300/acre for Sanitary Sewer District 7 will apply to all upland acreage, this rate will be indexed at the end of January 2018 to the 2018 rate and will apply to this parcel.
Standard utility and drainage easements must be dedicated along all lot lines and over areas of delineated 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. A Drainage and Utility easement will need to be dedicated in the north west corner of the Oakwood Ponds development to accommodate the proposed Lever Street Lift Station.
Development requires a National Pollutant Discharge Elimination System (NPDES) Phase II General Storm Water Permit for Construction Activity from Minnesota Pollution Control Agency (MPCA). A prerequisite to the MPCA permit application includes preparation of a site Storm Water Pollution Prevention Plan (SWPPP) for the development site.
Rice Creek Watershed District review and permit is required.
Construction contract documents shall include a mass (rough) grading, erosion protection, sediment control, development, utilities, roadway, and storm drainage plan sheets. Plans shall detail wetland information, tree preservation, erosion protection, sediment control, proposed grading contours, utilities, roadway geometrics, storm drainage, storm water quality management, custom lot-grading, house type, and house elevation information. Additional information is required on adjacent parcels to the south to confirm that existing drainage patterns are being addressed. The development plan shall indicate all structures will be protected from flooding. Supporting wetland delineation report, geotechnical investigation report, soil boring logs and hydrology report shall be included in the submittal for City review and approval.
The Developer shall process a Letter of Map Change with FEMA prior to issuance of building permits within the unnumbered A-Zone on the FEMA flood map. Developer shall provide all FEMA paperwork and structure as-built surveys to homeowners at time of lot closing. Developer is responsible for following through with FEMA as necessary to receive final FEMA documents and to provide those documents to the homeowners, and to record the final documents on the certificate of title for each parcel in the development.
As-built surveys shall be required to verify structure elevations, custom grading requirements, and final lot grading elevations.
The final plat is consistent with the approved preliminary plat, Resolution No. 17-147.

By motion, approve the Resolution.
