We are therefore requesting a permit be issued for the construction of a new septic system to accommodate the home. A well was recently drilled on the lot to provide information for development of the subdivision. The attached Site Plan and backup documentation identify the location and configuration of the proposed 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 absorption trenches and alternate site indicate silty gravel (GM). The percolation rate of the soil was determined to be 6 to 15 minutes per inch. No groundwater was found during the placement of the test holes and none was found during the monitoring period. An application rate of .8 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,250 -gallon septic tank and a 63' long by 3' wide by 6' 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 9.0'. 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 northwest. The new trench will be constructed 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 Lot 6, Inlet View January 6, 2017 Page Two 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. 1 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, w4t-L� Michael E. Anderson, P.E.

Two cleanouts are required between the tank and the drainfield. 7. Final grading over the tank shall be such that a positive slope exists away from the septic tank. DRAINFIELD CONSTRUCTION: 1. The drainfield shall be constructed to the dimensions shown on the design. The bottom of the trench shall be within 2" of level. 2. Distribution piping must be placed level with perforations down atop a level bed of drainfield rock. Rock should then be placed over the pipe to provide a minimum of 2" of cover. 3. A silt barrier or geotextile fabric must be placed between the drainfield rock and the natural soil backfill. 4. Monitor tubes must be 4" in diameter and installed at the locations shown on the design. The portion below the distribution line must be perforated. 5.

Test wells must be placed prior to the approval of the subdivision to verify sufficient water is available to serve the new subdivision. The owner of the parcel intends to construct a new well on proposed Lot 6 as part of the aquifer study. The well will remain in service after the subdivision is approved to serve a new single family home proposed for the lot. We are therefore requesting a permit be issued for the construction of a new well to accommodate the home and provide information for the aquifer study. The attached Site Plan and backup documentation identify the location and configuration of the well and the septic system reserve area on the lot. Also identified on the plans are the proposed wells and septic reserve areas on surrounding lots also proposed for the subdivision. 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 ground surface on the lot in the area of the wells and septic systems is flat with only a very shallow grade to the northwest. The new well will be constructed in conformance with Municipal requirements. The new septic well will be constructed a minimum of 100' from all septic reserve areas proposed for the subdivision and all existing septic systems in the area. If the system is constructed in accordance with our design the following statements apply: 1. The well, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. Lot 6, T16N R1W Section 32 Proposed Lot 6, Inlet View Subdivision November 30, 2016 Page Two 2. The well, 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 well, 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 well, 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.
