Hakanson Anderson Assoc., Inc. Engineers, Surveyors & Landso~,ne Architects September 26, 1989 Mr. Gerald Zimmerman, Chairman Ramsey Planning & Zoning Commission City of Ramsey 15153 Nowthen Blvd. N.W. Ramsey, MN 55303 Re: North Forty 3rd Addition Preliminary Plat Review Dear Mr. Zimmerman: As requested, we have reviewed the preliminary plat for North Forty 3rd Addition and offer the following comments: 1) North Forty 2nd Addition is a 70.26 acre development with 21 residential lots. Ail of the lots meet the City's minimum width and area requirements of 200 feet and 2.5 acres, respectively. According to the Anoka County Soil Survey, soils in the area consist of Hubbard coarse sand with the exception of Lot 2, Block 1 which has an area with high water. Based on the soil borings, the water table on the site varies from elevation 867 to 871. Therefore, all the proposed lots have adequate Class I soils for on-site wastewater disposal systems. 3) In review of the proposed drainage improvements, it is proposed to pond all the runoff on the plat. In review of the drainage calculations and the grading plan, all of the drainage areas with the exception of area E do not provide for adequate storage. 4) Since none of the detention areas have outlets, the building elevations of the lowest floor should be set at least three feet above the highest known water levels as stated in the Environmental Protection Ordinance. 5) In review of access to the plat, the primary access will be from Armstrong Boulevard N.W. (County Road No. 83). The proposed access to the County Road should be reviewed by the Anoka County Highway Department. The proposed plat is proposed to connect to the existing streets in the surrounding Whispering Pines Estates development.
