Opened and Closed on the same day, or b. Covered, sealed, and heated to prevent freezing 3 Special Provisions: A test hole is required prior to construction of the absorption field, in the location shown on the site plan, to confirm minimum separation to impermeable soil and seasonal high groundwater, as well as percolation rate. Construction may proceed at your own risk prior to 7-day groundwater monitoring. If results require a design change, construction shall stop pending approval of a change order. Please submit results with the inspection report (or change order, if required).

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 other well or septic system, whether on this lot or adjacent lots. The ground surface on the lot has a moderate slope of around 15% for the front 80’. For around 25’ after that it is much steeper, it levels out for a little, then the back half slopes down towards Potter Valley Rd. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contours are shown on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. This design is based upon a Northern Geotechnical test hole from 2025. We propose a confirmation test hole be dug prior to installation to confirm presence of receiving soils and separation distances to impermeables and groundwater. Wells on this and adjacent lots are shown. The new system 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 6’ away. Please refer to the attached test hole log, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
