We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate 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 the proposed septic systems and wells on adjacent lots. Drainage arrows and ground surface contours 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 primary absorption trench indicate t. The percolation rate of the soil was determined to be .5 s;,m minutes per inch. The mechanical analysis performed on the material indicated 59.5% it sand. A sand liner is therefore unnecessary. Groundwater was found during the placement of the test hole at 16' and was found at 15' during the monitoring period. An application rate of 1.0 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 45' long by 5' wide by 4' effective depth absorption trench to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 3.0' below the surface and the total depth will be 7.0'. 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 is flat with only a very shallow grade to the northeast. The new trench will be constructed in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' CO 1 Lot 1, Inlet Vue Estates July 18, 2017 Page Two 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: 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, at-e12---7 ,00:01.11%‘t Michael E.
