The attached drawing shows the location of the house and its proximity to the absorption trench. The area available on the lot for a septic system is restricted by bedrock and the southeast corner of the lot provides the most acceptable area. The absorption trench is at least 8' from the proposed foundation which is less than the 10' required. The influence line of the footing when projected down at a 1:1 slope does not encroach into the absorption trench. The bottom of the footing is a minimum of 3.5', below ground and almost level with the bottom of the trench. We therefore conclude the location of the absorption trench will have no adverse impact on the proposed foundation. We hereby request a waiver be issued allowing the house to be 8' from the edge of the absorption trench. Sincerely, Michael E.

The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system along with the alternate site. The subdivision is served by a public water system and the septic system is more than 200' from the Class A Well in the area. Drainage arrows are shown on the site plan showing the grade and direction of flow on the lot. The drainage pattern will not be changed as a result of this project. The test holes placed on the lot in the area of the absorption trench and alternate site indicated gravel (GP) from 1.5' to 3.5' below the surface. This lense is underlain by a tighter silty gravel lense (GM). The percolation rate of the GP layer was determined to be between 1 and 5 minutes per inch. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. An application rate of 1.2 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,500-gallon STEP tank and 2-50' long absorption trenches each 5' wide by no' effective depth. The elevation of the distribution line in the absorption trench will be 1.5' below the surface and the total depth will be 1.5'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trenches and 4' over the STEP tank. The ground surface on the lot in the area of the absorption trenches is basically flat with a slight slope to the east. The new trenches will be constructed parallel with the contours of the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 10' from water services and Lot 19, Block 1, Southpark No. 2 May 3, 2011 Page Two 100' from any surface water in the area. The STEP tank will be lower than the absorption trenches with the septic effluent pumped to the absorption area through a 1.5" PVC line. 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. 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.

Box 196650 Anchorage, AK 99519-6650 Subject: Lot 19, Block 1, Southpark Subdivision No. 2 Separation Distance Waiver Absorption Trench to Lot Line Dear On Site Services Engineer: Lot 19, Block 1, Southpark Subdivision no. 2 is plagued by dense silty gravel with slow percolation rates which restrict the area available for an absorption trench. Test holes recently placed at the southeast corner indicate clean gravel with acceptable percolation rates at sufficient depth to support an absorption system. This area, however, encroaches into the 10' setback from the property line. Soils at this location are well to poorly graded gravel which is normally effective in the absorption and treatment of septic effluent. Placement of the absorption trenches within 4' of the eastern lot line will not adversely affect neighboring lots. We hereby recommend a lot line waiver be issued allowing placement of the absorption system within 4' of the southern lot line. Sincerely, Michael E. Anderson, P.E.
