The length of the trench was increased because of silty sand SM/~ layers in the effective absorption sidewall area of the trench. Because of the narrow width of the layers, conduction of a percolation test, representative of the entire side wall area, is impossible. Therefore, the SM/ML layers were not counted in the trench depth. Thus, while there is 42" of gravel in the trench, effective gravel depth is 12 inch~s, therefore, length of trench was increased from 41' If you have any questions, please call.

U S, I1l£. ~y 3~ 1984 SOILS FOR EKLUTNA GATE SUBDIVISION BACKGROUND: This area lays just east of the Eklutua interchange of the Glen Highway in the north part of the Municipality of Anchorage. The area is a general flat plain area and is located between the Glenn Highway and the Alaska Railroad. It is a new area that is being subdivided for additional housing. Vegetation on the area is predominately large cottonwood interspursed with spruce. The south portion of the area contains a heavy growth of spruce and appears to have been formerly cleared. The top soils consists mostly of organic debris and sand. The under material is made up of mostly water deposited gravel and sand. Only at the very deep areas does silty, sandy gravels occurred. DISCUSSION: Test were performed in conjunctions with the requirements set forth "Design Manual for On-Site Waste Water Disposal System" EPA. Testholes were dug with a Ford rubber tired backhoe on May 1, 1984. Testholes were not able to be dug deeper than 11 or 12 feet during this test. The gravel material was very loose and the hole tended' to sluff in with depth. The objective of our testing was to determine the soils suitability for on-site septic system. The important soils classification are: 1). Soil depth 2). Depth to ground water. 3). Soil permeability The individual testhole soils logs are attached in the appendix. Shallow soil: Results of our testing indicated that bedrock depth were not obtained anywhere within the area. From the geolocial formations available it would appear that bedrock is not a factor in this area. Soil-Water: None of the test holes showed anY ground water. The only moist soils found were near the 12 foot depth and these were occassional layers of silty sandy gravels (GM). These soils were slightly moist but no free water was in that soil structure. Soils Permeability: All the soils in the area are highly permeable and should not create any problems with the installation of on-site sewer systems. In several instances we noticed layer~ of organic material (root mass) at depth below that which would normally be be found. It would appear that this area ha~ been overlaid with gravel several times in the recent geologic history. The root masses were in sandy material and we feel that thio will not inhibit permeability. Conclusions: Based upon our soils we feel that all the lots are acceptable for on-site sewer sTstems. Deep trenches or f£ve foot wide shallow dralnflelds are recommended in this area. Because of the looseness of gravel a five foot wide shallow alternate maybe necessary in some cases. Approved by~ h~DD, PE
