Minnesota 55323•Municipal Offices <br />On the North Shore of Lake Minnetonka <br />August 18, 1977 <br />I: <br />Mr. Kenneth Daniels <br />2905 Fox Street <br />Long Lake, Minnesota <br />Mr. Daniels: <br />55356 <br />The city engineer and inspector have reviewed the percolation tests and <br />proposed septic treatment area on your property. We feel that a drainfield <br />system can be designed for this area in conformity with Minnesota PCA standards <br />as proposed in WPC-40 for soils with percolation rates between 60 and 120 MPI. <br />In this situation, trenches should be constructed 48 inches wide and then lined <br />with at least 6 inches of loany sand prior to placement of the normal gravel <br />filter. Ihe design treatment area should be 330 sq. ft. per bedroom. <br />Plea^ submit a sketch of the proposed field layout and have your contractor <br />obtain the permit and install the system as soon as possible. <br />Sincerely, <br />‘r Olson <br />^st. Zoning Administrator <br />cc: Carl Widmer, Widmer Bros. <br />APO: be
