Hakanson Anderson Assoc.,Inc. Engineers, Surveyors & Landscape Architects February 28, 1989 Mr. Gerald Zimmerman Ramsey Planning & Zoning Commission City of Ramsey 15153 Nowthen Boulevard N.W. Ramsey, MN 55303 Re: Revised North Forty 2nd Addition Preliminary Plat Review Dear Mr. Zimmerman: We have reviewed the revisions for the preliminary plat for North Forty 2nd Addition and offer the following comments: 1) As previously stated, North Forty 2nd Addition is a 40.5 acre development with 13 residential lots. 2) Soil borings suitable in number to determine the water table throughout the plat and soil classifications to determine if the soil is suitable for on-site waste disposal systems were not provided as requested. Two borings were provided with the original submittal of the preliminary plat; These borings do not reflect the water table elevation on Lots 3-7, Block 1. 3) The additional area to be dedicated for parkland to provide access around the ponding area on the south boundary of the plat was provided to approximately elevation 871. Filling of the wetland may be required to construct a trail above elevation 871. In addition, the drainage calculations show that the high water level will be at elevation 873. Since the land dedicated is less than 10%, the balance will have to be paid in cash. 4) Easements for the drainageways and detention ponds are not shown on the plans. High water elevations are needed for all the ponds along with the grading plan for the ponding areas to provide for storage of a 100 year storm. 22.2 Monroe Street Anoka, Minnesota 55303 612/427-5860 Fax 612/427-3401 Eugene J.
