Hakanson <br />Anderson <br />Assoc., Inc. <br />February 8, 1988 <br />Mr. Dennis Cin <br />Chief, Regulatory Functions Branch <br />U.S. Army Corp of Engineers <br />1135 U.S. Post Office & Customs House <br />St. Paul, MN 55101 <br />Re: Gateway North Industrial Airport <br />Proposed Development - Ramsey, Minnesota <br />Dear Mr. Cin: <br />Engineers, Surveyors & <br />Landscape Architects <br />The City of Ramsey is contemplating the acquisition and improvement <br />of Gateway North Industrial Airport. An environmental assessment <br />report is currently being prepared for the proposed project and a <br />draft should be available later this month. <br />The proposed project requires the relocation of County State Aid <br />Highway 116 near a Type III wetland (Anoka County 118). Enclosed <br />is a copy of the Airport Layout Plan, an aerial photo and a <br />generalized wetlands map. The proposed right-of-way alignment is <br />shown on the enclosed plans. Actual roadway width would be 24 <br />feet. Final alignment of the roadway has not as yet been <br />determined, however, it appears that the roadbed itself would be <br />out of the wetland area. We would appreciate receiving any <br />comments that your office may have in this matter. <br />A second item of consideration is that storm water runoff from the <br />air field is planned to be drained predominantly to the east. <br />Discharge of some runoff to Wetland No. 117 is being considered as <br />well as the need for future detention basins. At ultimate <br />development, approximately 12% of the airport land area would have <br />impervious surfaces. Drainage concepts will be further refined as <br />the project moves into design development. We would appreciate <br />receiving your concerns in this regard as well. <br />222 Monroe Street <br />Anoka, Minnesota 55303 <br />612/427-5860 <br />
