[~nc~ineerin~ ~, [~nuironmenlal Sluclies January 30, 1984 Besse, Epps 'and Potts 2220 E 88th Avenue Anchorage, Ak 99507 Attention: John Epps Dear John, On December 28-31, 1983 we drilled a series of test holes on Lots 2, 8, 10, 12 and 14, Block t Spring Hills Estates Addition No 1. These holes are in addition to the holes drilled on the Spring Hills Estates before this area was excluded. The new soils logs are attached. Our findings indicate that this addition will support on-site sewer systems. It may be necessary to sp~t the houses so that the higher areas are used for waste disposal systems. The Creek setback will generally force sewer systems into the higher area. We had problems in drilling to 14 feet on Lot 2 because of the dense gravel strata at about 9 feet deep. We experienced a similar problem along the same elevation on the up stream part of the original subdivision. When we used a beck hoe to excavate those original holes we found very large cobbles and boulders which rejected our drilling efforts. I believe this lot can best be developed using a shallow bed or 5 feet wide drainfield. The soils encountered, should not cause foundation problems if the houses are kept toward the higher grounds and away frcm the creek. If shallow ground water is encountered a foundation drain should be used to keep the crawl space dry. As this is an environmentally sensitive area, the potential buyers should be alerted to our rec~mendations. If you have any questions, please let ma know. 1200 UJest 33rd r~uenu¢, Suile ~ · P~nch(~r~q¢, Alosk 99503 ' (907) 276-1361 MUNICIPALITY OF ANCHORAGE DEPARTMENT OF HEALTH AND ENVIRONMENTAL PROTECTION 825 L.
