We are therefore requesting a permit be issued for the construction of a new septic system to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the existing well and septic system along with the alternate site. Also identified on the plans are the existing well on surrounding lots. The subdivision was only recently platted and recorded and this is the first lot to be developed. A well is in place on the lot which was used during the design phase of the subdivision for the aquifer test. It will be utilized to provide water to the new home. A four-bedroom Advantex Treatment System will be placed on the lot in conformance with the subdivision plat notes. No conflicts exist between the proposed septic system and well or septic systems and wells to be developed 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. Two test holes were placed on the lot in the area of the absorption trench and alternate site. The logs indicate silty gravel (GM/GP) with sand in the zone specified for the absorption trench. The percolation rate of the soil was determined to be 2-3 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 4.0 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 Advantex Treatment Tank 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 6' below the surface and the total depth will be 10' to compensate for the steep slope on the lot. A Lot 3, Block 3, Potter Highlands Subdivision No. 2 May 13, 2015 Page Two 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 slopes to the west at a steep grade. A trench to slope waiver is attached for review and approval. 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: 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, Michael E. Anderson, P.E.

The developer of the lot intends to place a system with gravity flow. We have located an area with acceptable soils, but both the primary and alternate sites must be placed on a slope greater than 25%. The distribution lines in the trenches will be placed as 6' below the surface. The 25% slope when extended from the sidewall of the trenches does not daylight less than 50' from the trench. We are therefore applying for a waiver allowing placement of the primary and alternate absorption trenches at the location shown. The soil encountered in the test holes is silty gravel with sand (GM/GP) which is very good for the absorption of septic effluent. No migration of effluent is expected to occur to the steep slope.
