t Ye'll- C�u NW, -, - , , <br />October 28, 1975 <br />Mr. Carl L. Kevlin <br />Crest Investment Corporation <br />Suite 118 <br />1500 L•'. 79th Street <br />Bloomington, Minnesota 55420 <br />545 Indian Mound <br />Wayzata, Minnesota 55391 <br />(612)473-4224 <br />Re: On Land Disposal Systems <br />For Mr. Vince Bernhardt's Property at <br />Lot 4, Block 1, Riedel Company's Stubbs <br />Bay Addition <br />Dear Mr. Kevlin: <br />Enclosed are specifications and drawings for a proposed <br />disposal system for the above referenced project. <br />On October 13 and 14, 1975 percolation tests were <br />conducted on the above mentioned property at the loca- <br />tions described en Figure 1 of the enclosed drawings. <br />Testing consisted of a soil boring to a depth of three <br />and a half feet and six percolation test holes. <br />Soils encountered were light brown sandy clay and some <br />reddish brown and grey clay interbedded. The soil <br />boring was made at an elevation about five feet lower <br />than the area where the percolation tests were run. No <br />,round water was encountered in the soil boring hole, <br />therefore, the ground water table is greater than 8 <br />feet deep in the percolation test area. <br />Percolation rates for the test holes averaged 4 minutes <br />per inch. These rates indicate a natural soil suitable <br />for use as a d):ain field for on site disposal. <br />Stated percolation rates are averaged for the locations <br />shown and no guarantee is implied or expressed that these <br />conditions exist for the entire proposed drain field area. <br />
