Box 196650, Anchorage, Ak 99519-6650 (907) 343-7904 Ref: Proposed Septic Upgrade for Eklutna Gate First Addition; Lot 10, Block 1, To whom it may concern: The existing 4 bedroom house is served by a community water system and a private septic system. The owner has requested a septic system upgrade from Alaska Native tribal Health Consortium (ANTHC). We are proposing that a new 1250 gallon septic tank and a bed type drainfield. Two test holes were excavated on the property. The drainfield will be designed around the 30 foot radii of this test hole. Comments regarding the design are summarized as follows: 1. SOILS: See the attached logs which shows the soil classifications, groundwater monitoring, and the percolation test results. 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications. 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed septic system. 4. TOPOGRAPHY: As can be seen on the attached design drawing, the average topography is generally flat within 50 feet of the proposed drainfield. In short, there are no slope concerns. We are unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If have any questions, please contact us at 337-6179. Thank you for your assistance. Pres ;s, P.E., M.S. Attached is a site plan drawing, a design drawing, a detail drawing, and two soil logs, which are all part of the design package for this septic system. (Contact G.E.G.

I~n~ji,~r!n~j $ I~,uironm~nlol Stu~li¢~ May 3, 1984 SOILS FOR EKLUTNA GATE SUBDIVISION BACKGROUND: This area lays just east of the Ek!utna 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 I1 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 alightly moist but no free water was in that ~oil 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 layera of organic material (root mass) at depth below that which would normally be be found. It would appear that this area has been overlaid with gravel several times in the recent geologic history. The root masses were in sandy material and we feel that this will not inhibit permeability. Conclusions: Based upon our soils we feel that all the lots are 1:200 LUest 33roi ~uenu¢. Suite B · )~nchorog~./~los~a 99~3 · [907) 276-1361 acceptable for on-s~te se~er systems. Deep trenches or five ~ooC ~ide shallow drainflelds are recomended in this area. Because of the looseness of gravel a five foot wide shallow alternate maybe necessary in some CaSes.
