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. Lots on all sides with exception of the westerly lot are vacant so 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 test hole was placed on the lot in the area of the absorption trench and alternate site. The logs indicate gravelly sand (SM) with silt in the zone specified for the absorption trench. 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. Plat notes require the use of nitrate reducing septic system s on the lot. We have therefore specified an Advantex Treatement System to accommodate four bedrooms. An application rate of 4.0 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new Advantex Tank and AX-20 Pod and a 15' 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' 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 surface of the lot will allow gravity flow from the pod to the absorption trench so an add on lift station is not required. Lot 6, Block 2, Shangri La East Subdivision September 25, 2013 Page Two 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 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.
