SSOCIATES <br />ENGINEERS & LAND SURVEYORS, INC. <br />July 7, 1993 <br />Mr. Steve Weekman <br />City of Orono <br />P. O. Box 66 <br />Crystal Bay; MN 55323 <br />RE: Cheyenne Builders <br />Our Job No. 93320 <br />Dear Steve: <br />• <br />I <br />�C—rwl a no <br />Enclosed is a revised copy of our site evaluation for Cheyenne Builders on Lot 6, Block 1, <br />RINGERSWOOD. As per your comments, we have changed the size of the perforations from <br />1/4 inch to 7/32 inch in the mound laterals. This drops the pump to output at least 42 G.P.M. <br />As per the unusually slow per rates for these soils, our crew encountered a saturated condition <br />on both the primary and alternate sites. This saturation I believe is due to the extremely wet year <br />we are having and that the testing was done after a period of heavy rains. <br />If you have any questions, please feel free to contact my office. <br />Sincerely 1 <br />Edward J. Otto, res. <br />Otto Associates, Inc. <br />EJO/md <br />Encls. <br />cc: Cheyenne Builders <br />9 WEST DIVISION STREET - BUFFALO, MINN. 55313 - (612) 682-4727 <br />
