BOX 240773 ANCHORAGE, AK 99524 April 23, 2004 Municipality of Anchorage Development Services Department On -Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Subject: Lot 2, Block 5, Skyway Park Estates Subdivision Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: The owner of Lot 2, Block 5, Skyway Park Estates Subdivision intends to construct a four-bedroom home on the lot. We are therefore requesting a permit be issued for the construction of a new septic system to serve the new home. The subdivision is served by the Municipal water system and no conflicts exist with adjacent septic systems or wells. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system and alternate site. The current drainage pattern is also identified on the Site Plan. The drainage pattern will be maintained after development of this lot is complete. A test hole placed on the lot in 1979 indicated silt with some gravel in the area of the absorption trench. The accepting soils were tested and found to have a percolation rate of 9 minutes per inch. No groundwater was found during excavation and none was noted during the monitoring period. A permit was issued to construct a septic system on this lot in 1979. The permit was issued based on an application rate of 160 square feet per bedroom. The test hole and permit are now more than 25 years old and we are proposing to provide acceptable test hole data prior to the construction of the new system. Acceptable soils logs and percolation test data will be provided along the inspection report and certified as -built for the new system. Our design includes the placement of a new 1,250 -gallon septic tank along with a 50' long by 3' wide by 8' effective depth absorption trench to collect and treat the sewage generated in the house. Our application rate is nearly 188 square feet per bedroom approximately 18% larger than the rate used for the permit issued in 1979. The bottom of the trench will be 9.5' below the surface. The distribution pipe will be 1.5' below the surface. A minimum of 3' of cover will be placed atop the trenches and a minimum of 4' of cover will be Lot 2, Block 5, Skyway Park Estates April 23, 2004 Page Two placed atop the new septic tank. The ground surface on the lot slopes at shallow grades from east to west as shown on the Site Plan. The absorption trench will be constructed parallel with the slope of the ground surface as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 10' from the water service proposed for the lot and on adjacent lots. It will also be constructed a minimum of 100' from any surface water in the area. If the system is constructed in accordance with our design the following statements apply: 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. 2. 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. 3. 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. 4. 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, n ' Michael E. Anderson, P.E.

Dear Mr. Dunning: At your request, I conducted a soils investigation at the proposed location of a sanit -. ry sewer system on the subject lot. This investigation, which was accomplished June 17, 1979, consisted of the inspection of soils removed during the drilling of a 7.6.5 footdeep test hole, using 4 inch diameter solid flight augers, powered by a trailer mounted Mobile B-34 drill rig. - - After completion of drilling, Test Hole No. 1 was filled with water and a percol.ition test - performed. The results of this test are tabulated on an accompanying sheet. The soils encountered are graphically shown on the accompanying test hole boring log, '"he soils consisted of a surficial layer of organics and organic silt 1.5 feet thick, over_.ying a silt with some gravel and a trace sand 9.5 feet thick, in turn overlyima'a silt with -a trace clay 2.5 feet thick, underlain by a silty gravc-1 with some sand 1.5 i.'eet thick, .. tui: underlain by a clayey silt with a trace gravel 1.5 feet thick. No pater table was encountered. The topography of the lot shows a gentle to moderate down slope in northwesterly dire_ . on. Vegetation presnt on the lot consists of moderately dense very large spruce and birch tree;, to 75 feet tall, with scattered patches of willows and alders, and a low (;_)und cover of mosses and grasses An accompanying sheet contains the graphic test hole boring log, two lot topography profiles, and a sketch showing the subject lot with the approximate locations of the test holes in relation to the property lines. I recognize that this is the second soils investigation performed on your properi-y. I have- noted the location of the other test on the lot sketch. The disLance of approximately feet between the test I performed and the previously performed test that failed, plus cc:_ approximate elevation difference of 8-10 feet, are responsible for the stratagraphic change that allowed this soils investigation -percolation test Lo be successful. I appreciate the opportunity to be of service to you. Please contact me it you have a:.. questions regarding this soils investigation. Very truly yours, Michael B. 13 rgmann Consultin Geologist Attachments: Drawing of test hole boring log, profile sketches, and location sketch.

Percolation test performed on June 17, 1979, using 'fest Hole No. 1. The test hole was drilled to a total depth of 16.5 feet, but when measured with tape before performing percolation test, it was noted that it had caved in at the 9.0 foot depth. The percolation test was performed by filling the hole with water and measuring the drop periodically for one and one half hours. On June 18, 1979 a second percolation test was performed in the same fahion using the same test hole. It. is tabulated below the original percolation test.
