On the East it is bordered by Audubon Hills and on the North by Raven Woods and Dafoe Subdivision. RECEIVED Land Forms The subdivision is' characterized by a series of knolls with interconnecting valleys. There are two distinct drainage patterns, one from the South East corner to the North West and one from the South to North. A sketch, Figure 1, is attached ~to show the drainage patterns. Vegetation The knolls are generally covered with white Spruce and Birch. Some of the denser soils have stands of what appears to be Black. Spruce. The valleys contain sparce birch and spruce with heavy concentrations of alder. soils Soils were tested with a Mobile B24 ski mounted drill towed by a Bombi track rig. Several holes were d~illed with a Mobile Minuteman in areas where access was limited. The soils for specific holes are shown on the attached soils logs. Percolation tests are included where appropriate. In general the soils on the west two thirds are sands and sandy gravels. The soils on the east third range from silty gravels to silts with occasional seams of gravels. These general soils are shown on Figure 1. Water was generally not found above 12~13 feet except for one hole which had water at 9 feet. Conclusions The thirty five soils tests indicate that this subdivion is acceptable for on-site sewer systems. The land forms and soils tend to support smaller lots in the western two thirds and larger lots on the eastern third except in the areas of good gravels where smaller lots are acceptable. The extreme Northeast corner is acceptable for homes if built on the hills. 1220 J.Ucs! 25th Au~nu¢ · Anch0roq~, Alaska 99503 · (907) 276-1361 Recommendations Because of the land forms and soils types the final configuration of this subdivision should accomodate the various soils ~ypes. Future development to the south and east of this subdivision may increase water flow through this subdivision. A drainage pattern should be established in specific areas through use of small explosive changes or selected ditching. This pattern should be both esthetically pleasing and environmentally sound.
