Pate 2703 Blueberry Anchorage, Alaska Project: Percolation Te'st - Lot 4, .Block 2 Elmore Subdivision Gentlemen: A percolation test has been performed on the subject lot. The test was performed in a previously excavated pit. The test data are shown on the · attached sheet. Because of the difficulty of digging, the actual test hole used is not considered to be a definite measure of the percolation rate of the area. The measured rate was 1-inch per 4 minutes. Our ~ast experience tn this type of soil leads us to believe that a rate of 1-inch per 10 to 15 minutes should be used for design purposes. The water level in the pit may require a redesign of your.se, epage. pit. As we discussed during our phone conversation, a tandem, rather than a stacked arrangement of the concrete rings, may be feasible. We suggest that you take this report along with'a topographic~lot. plan to'the Greater Anchorage Health Department for a discussion of What arrangement will meet their criteria.
