IK 96L SUBJECT: Lot 17A, Block 2, Near Point Knoll Subdivision Septic System As Built The test hole utilized to design the septic system for Lot 17A, Block 2, Near Point Knoll Subdivision was placed during the subdivision phase of the project. The location was not accurately depicted on the subdivision map. The scaled location was shown on the original site plan. Evidence of the test hole was found during construction of the septic system trench and shown on the as built. Its location on the as built drawing is slightly different than that shown on the original design. The absorption trench, however was constructed in close proximity to the test hole and soils encountered in the trench were exactly as shown on the test hole log.

We are therefore requesting a permit be issued for the construction of a new septic system to serve the new home. A Class A Water System serves the subdivision. The Site Plan and backup documentation identify the location and configuration of the proposed septic system and alternate site. The Class A well on the adjacent lot is also shown along with the water service to this lot. Existing spot elevations and the current drainage pattern are also identified on the Site Plan. The drainage pattern will be maintained after development of this lot is complete. Test holes placed on the lot during the subdivision phase indicated gravel with some silt and sand in the area of the absorption trench. The accepting soils were tested and found to have percolation rates of 1 to 5 minutes per inch. No groundwater was found during excavation and none was noted during the monitoring period. Our design includes the placement of a new 1,500 -gallon septic tank along with a 63' long by 5' wide by 4' effective depth absorption trench to collect and treat the sewage generated in the house. The bottom of the trench will be 7' below the surface to provide the required separation from the water table. The distribution pipe will be 3' below the surface. A minimum of 3' of cover will be placed atop the trenches and a minimum of 4' of cover will be 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 200' from the Class A well on the Lot 17, Block 2, Near Point Knoll Subdivision May 6, 2004 Page Two adjacent lot and 10' from all water services. 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: 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. 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, c a'J'--n Michael E. Anderson, P.E.
