We are therefore requesting a permit be 'issued for the construction of a new septic system to accommodate the home. A well was placed on the lot during the subdivision phase. 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 well on'the lot and those on surrounding lots. This is a new subdivision and the first loth to be developed. Neighboring lots are currently vacant. No conflicts exist between the proposed septic system and wells or septic systems on adjacent lots. Drainage arrows are shown indicating the surface slope of the property in the area of the new', septic system. I I A test hole placed on the lot in the area of the absorption trench and alternate site during the subdivision phase indicated a silty gravel (GM) material.. The percolation rate of the soil was determined to be 7 minutes per inch. No groundwater was' found during the placement of the test hole, and was not noted during the monitoring period. An application rate of .8 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,000 -gallon septic tank and a 57' long by 5' wide by 4' effective depth absorption trench to treat and dispose lof the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 3.5' below the surface and the total depth will be 7.5'. A minimum of 3' 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 northwest. The new trench will be constructed parallel with the slope as much as possible in Lot 2, Block 2, Roseberry Ridge Estates August 15, 2006 Page Two conformance with Municipal requirements. The new septic system will be constricted a minimum of 100' from all wells and any surface water and 10' the proposed and existing water services in the area. I If the system is constructed in accordance with our design the following statements apply: I 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. 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. I 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.
