We are requesting a permit be issued to construct a well and septic system on the property. The absorption trench will be oversized to accommodate future construction. The attached site plan identifies the location of the home and the proposed well and septic system. No conflicts exist between this proposed system and any other well or septic system on this lot or adjacent lots. The ground surface on the lot slopes to the southwest at 20% in the area of the proposed trench. There are slopes greater than 25% within 50 feet down slope of the trench, but the absorption trench design meets the steep slope criteria of the Municipal Ordinance and no waiver is required. Ground surface contours are shown on the site plan indicating the grade and direction of flow. Storm water drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. The new system will be a minimum of 100’ from all wells and surface water, 10’ from any water service and more than 5’ away from the septic tank. Please refer to the attached test hole log and plan and profile sheets for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

A 400' run is very long so I will utilize a 3" pump inline from the tank to assist the truck so the job can go at a more normal pace and save the wear on the pump truck. Good luck on the build and lets us know when you would like to be serviced. Michael 1
