OF I!EALTH & ENVIRONMENT,iL FitOTECTION RECEIVED This subdivision is located in Section 33, T14N, R3W and Sect[on 4, T13NR3W. It contains 280 acres with 56 lots and 5 tracts. It is in the lower reaches of the South Fork of Eagle River. Land forms This subdivision is in the lowe~ section of the valley and shows greater evidence of stream erosion into the U shaped valley floor. The slope of the stream is greater than in the upper reaches of the valley. Only a short distance to the north the river plunges over a waterfall. This waterfall at the valley mouth denotes it as a hanging valley. The northeastern portion of the subdivision is generally on a bench. The land on the portion of the subdivision to the west of the river is characterized by steep slopes with large open grassy areas. The western portion appears to have a large number of springs and rivulets which probably originate in the snow fields to the west. To the west of Red Ram Drive, %he slopes ar~ very steep. The southern most portion of the subdivision, blocks 5, 6 and 7 are slopes with benches below Sun Valley Drive. The area appears to be very well drained. Bedrock was not encountered. This subdivision ranges in elevation from 2200 down to 1520 feet. Vegetation With the wide range of elevation the vegetation varies from above timberline species to spruce, alder and poplar with an occasional birch in the lower areas. Portions of tile subdivision have been denuded for homesteading. In these areas the emergent vegetation is generally alder and grasses. Spruce are starting to show under the alder thickets in the normal successional pattern. Soils Soils in the subdivision were tested by a combination of wheeled and track backhoes and a Minuteman drill. Several areas could not be drilled with the portable drill because of the high rock content. Test holes 1 through 5 show the soils to be acceptable for on-site systems. A bed should be considered for lot 2, block 5 as the best soils are between 2 and 6 feet. All other systems should be standard systems. Individual soils logs are attached for each of the lots. ~220 (]J~st 251h J~u~nu¢., J~nch0rct§~, Alaska 99503 · (907) 276d361 Conclusions The land encompassed acceptable for on-site sewer Recommendations Further soils work is needed subdivision. by blocks 5, 6 and 7 appear to be systems, on the north portion of the SOILS LOG MUNICIPALITY OF ANCHORAGE DEPARTMENT OF HEALTH AND ENVIRONMENTAL PROTECTION 825 L.
