Hakanson <br />Anderson <br />Assoc., inc. <br /> <br />Engineers, Surveyors & <br />Landscape Architects <br /> <br />November 1, 1989 <br /> <br />Mr. Gerald Zimmerman, Chairman <br />Ramsey Planning & Zoning Commission <br />City of Ramsey <br />15153 Nowthen Boulevard N.W. <br />Ramsey, MN 55303 <br /> <br />Re: <br /> <br />Preliminary Plat Review <br />Trott Brook Ridge <br /> <br />Dear Mr. Zi~merman: <br /> <br />We have reviewed the above referenced preliminary plat which is <br />located in the R-iR Residential rural service area of the City. <br /> <br />Following is a list of comments resulting from our review of this <br />preliminary plat: <br /> <br />The proposed plat has been revised to include 10 lots and a <br />16.9 acre park. All of the lots will exceed the minimum width <br />requirement of 200 feet for road frontage. <br /> <br />Access to the plat will be from Yo!ite Street on the north and <br />Alpaca Street and 166th Ave. on the south. To eliminate the <br />168th Lane and Bison Street cul-de-sac, Bison Street should <br />be constructed north of the plat to 171st Street. The 165th <br />Avenue cul-de-sac will need a variance for exceeding the <br />maximum length of 600 feet. <br /> <br />As previously indicated, the amount of Class i soils in <br />Block 2 is questionable. Soil borings should be provided to <br />establish the water table elevation. <br /> <br />Zn review of the drainage, storm water will be directed <br />towards Trott Brook. Drainage calculations should be provided <br />for the design of the proposed storm sewers. <br /> <br />The 100 year flood level of Trott Brook is 871.4. Therefore, <br />all livable floors must be constructed at or above elevation <br />872.4. <br /> <br />ZZZ Monroe Street <br />Anoka, Minnesota 55303 <br /> <br />61Z/427-5860 <br /> <br />Fax 612!z27-3ZN1 <br /> <br />Eugene J.
