Box 66 <br />Cr>ial Bay, MN 55323 <br />RE: Scotch Pine Addition <br />City Zoning File #2065 <br />BRW File 3233AOO <br />Dear Mike: <br />This letter is in response to comments from your letter dated September 14,1995. <br />Specifically, I would like to address the environmental benefits from this project. <br />A budget analysis program was used to estimate the contaminant loading for the <br />before and after conditions for the proposed street vacation. The results of the budget <br />analysis show a contaminant reduction of approximately 50% for the drainage area <br />contributimi to the adiacent wetland and ultimately to Lake Minnetonka. <br />This analysis does not take into account the oils, rubber, and other garbage <br />commonly associated with street run-off that currently enters directly into the <br />wetland by way of the existing storm sewer. <br />A permit has been applied for through the Minnehaha Creek Watershed District, and <br />the plans for this project have been revised to reflect the comments of the Board. A <br />Site/Grading plan was submitted to your oflice on 9/13/95. which addresses erosion <br />control, utility adjustments, and pavement removal. <br />If you have any questions, please call me at 373-6362. <br />Sincerely, <br />BRW, INC. <br />S.Sandberg, FIT <br />Project Engineer <br />Sam Marfield <br />Keith Dahl/BRW <br />c:
