We are therefore requesting a permit be issued for the construction of a new septic system to accommodate the home. The lot is currently served by the AWWU water system. 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 and septic systems on surrounding lots. No conflicts exist between the proposed septic system or septic systems and wells on adjacent lots. In addition, the proposed septic system and alternate site are more than 200' from the community wells in the area. 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 test hole recently placed on the lot in the area of the absorption trench and alternate site indicated silty sand with gravel (SM) in the zone specified for the absorption trench. The percolation rate of the soil was determined to be 4.4 minutes per inch. No groundwater was found during the placement of the test hole, and none was found 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 1,250 -gallon septic tank and a 50' 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 ground surface on the lot in the area of the septic system slopes to the southwest Tract 2-C, Stewart No. 2 May 29, 2014 Page Two 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 allells and any surface water and 10' the proposed and existing water services in the area. P ,Lai e 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, 7v� Michael E. Anderson, P.E.

The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system.
