The attached site plan identifies the location of the home and existing well as well as the proposed septic location and alternate site. No conflicts exist between this proposed system and any wells, whether on this lot or adjacent lots. Drainage arrows 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 indicate silty gravel with sand. No groundwater or bedrock was found down to 17'. The percolation rate was determined to be around 3 min/in. An application rate of 1.2 gpd/sf was used in the design of the absorption system. We are proposing to place a new 1000-gallon septic tank with a deep absorption trench 3' wide x 25' long x 8' effective depth. The elevation of the distribution line will be 3' below the surface for a total depth of 11'. Soil will be mounded 0.5' 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 moderately, between 10-35%, with a steeper portion at the far back corner of the lot. Most of the property is under 25% slope, although downslope from where the house will go there are some steeper portions that approach 35%. The alternate site is more than 50' from this steeper area, but the primary site is located 25' away. We are requesting a waiver to locate the primary trench 25' from these steeper slopes. The 25% line of influence from the distribution pipe will not daylight on this slope, as shown in the attached profile. In addition, with the very fast-draining soils, there is not much possibility of effluent migrating very far laterally. There is no danger of contamination by granting this waiver. 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 20' 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, PE \. t 00 %*: 49TM *14 rf.
