We are therefore requesting a permit be issued for the construction of a new well and septic system to accommo~late the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. Also identified on the plans are the existing wells in the area and septic systems on surrounding lots. No conflicts exist between the proposed septic system and well or septic systems 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 storm drain easement is located to the south of the lot. This is not a drainage easement and no surface drainage is expected through this area. A rock lined drainage ditch traverses the lot at the southern boundary. The purpose of the ditch is to control excess drainage during extraordinary storm events. No surface water has ever been noted in the ditch. The test hole placed on the lot in the area of the absorption trenches and alternate site indicate silty gravel with sane (GM). The percolation rate of the soil was determined to be 40 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 .45 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 septic tank and 2-53' long by 3' wide by 8' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 3' below the surface and the total depth will be 11 '. A flow splitter valve will be placed to insure even flow to each trench. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed Lot 13, Block 2, Cross Point Estates Subdivision July 15, 2014 Page Two 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 at a shallow grade with some cress sloping from 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 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. 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.
