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 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. The alternate absorption trench will also be constructed and connected to the new septic system with a flow diverter valve for future use if and when it may become necessary. Test holes were placed on the lot in the area of the absorption trench and alternate site. The logs indicate silty sand with gravel (SM) in the zone specified for the absorption trench. The percolation rate of the soil was determined to be 4-5 minutes per inch. No groundwater was found during the placement of the test holes but rose to 10.5' below the surface during the monitoring period. An application rate of 1.2 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 2,000 -gallon septic tank and a 100' long by 5' wide by 2.5' 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 2' below the surface and the total depth will be 4.5'. The configuration of the alternate absorption trench will be identical to the primary trench. 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. Lot 1113-3, Birch Grove Subdivision June 27, 2016 Page Two CO -ir3 The ground surface on the lot in the area of the septic system slopes to the southwest. 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. 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, -711'- Michael Michael E.

That trench is in the area of the alternate site. It has been backfilled and compacted to near natural state with the same material excavated from the trench which was silty sand (SM). Typically over excavated areas in absorption trenches are backfilled with uncompacted sand. The in situ material is comparable to this material and the trench is now in a state similar to that required by the Municipality for trenches that are excavated to depths which encroach into the separation distance to groundwater. We therefore request this area be considered acceptable in its current condition for placement of an absorption trench. We hereby request the change order allowing development of the alternate site be approved. Sincerely, Michael E. Anderson, P.E.
