We are therefore requesting a permit be issued for the construction of a new septic system to accommodate the structure. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system along with the alternate site. Also identified on the plans are the existing wells on surrounding lots. The area is served by the AWWU water system and a new water service will be constructed to this lot No conflicts exist between the proposed septic system and wells on adjacent lots. 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. A test hole was placed on the lot in the area of the absorption trench and alternate site. The log indicates silty gravel with sand (GM) and some silt in the zone specified for the absorption trench. The percolation rate of the soil was determined to be 1.7 minutes per inch. Groundwater was found during the placement of the test hole at 11' below the surface and remained at that level during the monitoring period which included May 15, 2013. 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 2,000 -gallon septic tank and 2 - 40' long by 5' wide by 4' effective depth absorption trenches to treat and dispose of the effluent generated in the duplex. The elevation of the distribution line in the absorption trench will be 3' below the surface and the total depth will be 7'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank. The ground surface on the lot in the area of the septic system slopes to the north at N100' Lot 6, Block 1, Dale Briggs Subdivision April 4, 2015 Page Two shallow grades. 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 100' from all wells and any surface water and 10' the proposed and existing water services 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, Michael E. Anderson, P.E. Attachments MICHAEL E. ANDERSON April 6, 2015 Municipality of Anchorage Development Services Department On -Site Water and Wastewater Program P.O. Box 196650 Anchorage, AK 99519-6650 Subject: North 100' Lot 6, Block 1, Dale Briggs Subdivision Separation Distance Waiver Absorption Trench to Lot Line Dear On Site Services Engineer: The subject lot is only 100' in depth allowing very little area for an on site septic system. The lot and the surrounding area are served by the AWWU water system however and no conflicts will result from placement of the absorption trench at 6.3' from the north property line. Soils in this area percolate at rates less than 5 minutes per inch and little or no migration of effluent is expected. We therefore request a waiver be issued allowing the absorption trench system to be constructed 6.3' from the north property line. Sincerely, Michael E.
