Background
In October of 2015, 2016 and 2017, the applicant received approval of a preliminary plat one year extension from the City Council for a subdivision known as Sarah Jean Estates that includes approximately 5 acres and 12 lots and an outlot for storm water. The applicant has been working on completing similar single family projects on the west side of Blaine (Jackson Street).
The final plat proposal consists of subdividing approximately 5 acres into a subdivision with a total of 12 dwelling units. This application proposes single-family homes. Park Dedication will be required as part of the platting.
The developer is proposing to match the development standards, housing styles and platting requirements that were initially approved with the existing DF (Development Flex) zoning.
The proposed plat is located along the 127th Avenue alignment, east of Harpers Street NE.
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 west side of Jamestown Street, north side of 127th Avenue, and 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 2017 rate for Sanitary Sewer District 6-5 is $5,917 per upland acre and will be index in February for the 2018 rate. This development will be charged the 2018 rate for 4.50 acres.

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.
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 reviewed this plat.
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 36 (eight trees per acre) to be replaced. The 12 lots (with four corner lots) would normally plant 27 trees. Therefore, tree replacement requirements will require 9 additional trees on site. A landscape plan identifying these trees will need to be submitted prior to any building permits being issued.
The final plat is consistent with the approved preliminary plat, Resolution No. 14-181.
