The attached site plan identifies the location of the home as well as the proposed well, septic location and alternate site.No conflicts exist between this proposed system and any wells,whether on this lot or adjacent lots. This is a large lot with more than 120,000 square feet of surface area. The well radius is contained entirely on the lot. Drainage arrows and contours are shown on the site plan showing the grade and direction of flow. The drainage pattern in general will not be changed by the construction. The test holes placed on the lot indicated different soil conditions depending on location. To the north, we found poorly graded sand with silty gravel. On the south side of the lot, we found hard clay with sand in the upper 10',with silty sand below that.No groundwater or bedrock was found down to 20'. The percolation rate in the area we are placing the trench was determined to be between 5-20 minutes per inch in the deeper sandy soils. The trench will need to be below that upper section of clay. An application rate of 0.6 gpd/sf was used in the design of the absorption system.We are proposing to place a new 1,000-gallon septic tank with a wide absorption trench 5' wide x 75' long x 4' effective depth.The elevation of the distribution line will be 10'below the surface for a total depth of 14'. Soil will be mounded .5' above the trench. A minimum of 3' of fill will be placed over the absorption trench and 4' over the septic tank. The ground surface on the lot slopes to the southwest at grades in excess of 25%,but it is over 50' from the area where we are placing the trench. The new trench will be constructed parallel to the slope as much as possible. It will be a minimum of 100' from all wells and surface water,and more than 5' away from the septic tank. The alternate site is located more than 10' away. If the system is constructed as designed, it will have no adverse impact: • On the wells in the area or those to be constructed in the future. • On existing septic systems in the area or those to be constructed in the future. • On reserve space on any lots located in the area. • On drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Benjamin Schiller, P.E.
