Box 66 <br />Crystal gay, Minnesota 55323 <br />Subject: Percolation Tests <br />Lot 6, Johnson's Rearrangement of <br />Abbey's Long Lake Addition <br />Dear Mike: <br />We have reviewed the percolation tests submitted on the <br />sutject project, and it appears to be acceptable for the design <br />of a drainfield. We would, however. caution you that when <br />inspection is made of this to ascertain that it is constructed <br />with no core than the proper amount of slope across the drain - <br />field. The area is rather hilly and care will need to be ex- <br />ercised to insure that this is done properly. <br />If you have any further questions, please do not hesitate <br />to contcct us. <br />Very truly ycurs, I <br />McCOMBS-KNUTSON ASSOCIATES, INC. <br />Williah H.
