SUBJECT: Tract 6, Siefker Subdivision Septic System Construction Permit £ Test holes used f.o.r the des gn of the septic system upgrade on.the subject lot were placed in 1990. It is not possible to monitor the groundwater at th~s time as a monitor tubes have been removed. We will, however, place a monitor tube prior to construction of the trench upgrade and monitor the groundwater for 7 days. Results will be submitted with the septic system as-built. Please issue the septic .system construction permit with this condition if it is acceptable to you. Please let me know if you have any questions or additional information is required. October 4, 2001 Municipality of Anchorage Development Services Department On-Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Subject: Tract 6, Siefker Subdivision Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer:. The owner of the subject lot is currently selling his house and must upgrade his septic system to obtain a Certificate of Health Authority Approval. We are therefore requesting a perm t be ssued for the construction of a new septic system t.o serve the three-bedroom'home. The attached Site Plan and backup documentation identi.fy'the location and configuration of the new septic system and the parameters used m the design. Also identified on the plans are the location of the existing septic system and well on the lot and the test hole location. Existing drainage patterns are shown and will not be altered by the development of the lot. A Bull Run Flow Diverter Valve will be installed and tied in to the existing at~sorption trench to aIIow use at a future date. In addition a Flow Divider Valve will also be installed to insure even effluent flow to each segment of the new trench. Two test holes were placed near the location of the existing absorption trench in 1992. These test holes are suitable for use in the design of the new system and are presented for your review. Percolation tests will be performed during construction to verify the soil conditions noted on the existing logs. These logs indicate fine clean sand with some silt is found near the location of the new absorption trench. Pemolation tests in the material resulted in rates of lessthan 1 minute per inch. Groundwater was found during the placement of Test Hole No. 1 at 11' and remained at that elevation during the monitoring period. No water was noted in Test Hole No. 2 at any time. We are therefore proposing to place a 5' wide absorption trench system .w, ith 1.5' of gravel beneath the distribution pipe. The total depth of the trench will be 6. The distribution pipe will be placed at 4.5' below the ground surface to provide sufficient drop from the septic tank to the absorption trench. The total length of the new absorption trench will be 60' in two segments of 30'. The ground surface on the'lot slopes as shown on the attached Site Plan with only minor slopes near the proposed sept. ic system site. The new absorption trench will be constructed on a fairly fiat surface ,n conformance with Municipal requirements and parallel to ground contours where possible. All components of the new septic system will be constructed 100' from the existing well on the lot. · Tract 6, Siefker Subdivision October 4, 2001 Page Two If the system is constructed in accordance with our design the following statements apply: 1. .The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely. Michael E. Anderson, P.E.

ALASKA 99518 907-344'4711 Mr. Dan Bolles Dept. of Health and Human Services Municipality of Anchorage Box 196650 Anchorage, Ak. 99519 Re; Tr. 6, Siefker s/d August 10, 1992 Dear Mr. Bolles: The referenced lot has a nearly failed crib and a concrete septic tank - both within or very near the lot well's 100 feet radius. The owner has decided on his own to bring the septic system up to code. The lot slopes to the west at about 2% or so and a drainage ditch runs along Cange. Most development has occurred on the west half of the lot. All adjacent lots are developed but their wells and septic systems were apparently constructed without permits. Even if all ef these lots' wells were Class C, this new improvement would not encroach on the protective radiuses. Soils are a uniform sized fine sand. I will give the Department a sample for sieve analysis for future reference. A perfectly graded SW may have a smaller pore size but I believe that this sand is nearly ideal for filtration and the formation of a bio-mat. Based on current regu].ations, no affect on adjacent lots is expected. The owner has decided to install only a single trench which is 125% of the required size instead of the alternated trenches shown. This change will be redrawn on the as-built. Please call if you have any further questions. EFCFIVED AUG 0 Munic~pahty of Anchorage Dept.
