Background
Staff Report Prepared by Lori Johnson
Lennar Corporation received approval from the city council in January 2020 to develop 42 acres on the east side of Lexington Avenue and north of 125th Avenue for the purpose of constructing 97 single family homes in a development known as Lexington Cove. The first addition of the plat, with 59 lots, is known as Lexington Cove 1st Addition. The second and final addition, which is currently being proposed, is 38 lots and will be known as Lexington Cove 2nd Addition.
The 38 lots will be used for single family homes, while Outlot A will be used for storm water/drainage purposes.
Park dedication will be required for the 38 new lots being constructed at the rate of $4,449 per unit, for a total park dedication fee of $169,062. This amount must be paid prior to releasing the plat mylars for recording at Anoka County.
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.
Trunk Sanitary Sewer area charges become due with platting for upland acreage. The 2020 rate of $6,652/acre for Sanitary Sewer District 7 will apply to all upland acreage platted in 2020.
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 ensure access.
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.
A Rice Creek Watershed District review and permit are required for this project.
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 if any of the development is 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.

The final plat is consistent with the approved preliminary plat, Resolution No. 20-15.
