Hakanson Anderson Assoc.,inc. Engineers, Surveyors & Landscape Architects February 27, 1989 Mr. Gerald Zimmerman Ramsey Planning & Zoning Commission City of Ramsey 15153 Nowthen Blvd. N.W. Ramsey, MN 55303 Re: Preliminary Plat of Wildwood Estates Dear Mr. Zimmerman: We have reviewed the revised Wildwood Estates Preliminary Plat as requested. Following is a list of comments resulting from our review of this plat: As previously stated, the proposed 71.8 acre development consists of 23 lots with minimum lot sizes of two and one half acres. In review the soils, mottling was present in several borings. City Code requires each lot contain 25% Class I soils or soils with seasonal groundwater less than 6 feet from the surface. To meet this requirement, the developer has agreed to grade the deficient lots to provide 27,225 square feet or 25% of 2.5 acres of lot area above the highest observed water table. Lots that will require grading are Lots 5 - 8, Block 2. The building setback from the Northern Natural Gas line should be shown. Calculations for sizing the culverts were not provided nor were the grading and drainage plan for the ponding areas. As noted on the review letter, a small area in the vicinity of Lots 3, 4 and 5 of Block 2 does not appear to have a drainage outlet. A ponding easement may be required. Also drainage easements over the low area of Lots 2 - 4, Block 1 and crossing the exception should be provided. 5. Specifications for the street plans should be provided. 222 Monroe Street Anoka, Minnesota 55303 612/427-5860 Fax 612/427-3401 Eugene J. Hakanson, RE. James M. Winter, LS. Lawrence G. Koshak~ eter
