The attached site plan shows the locations of the home, proposed well, septic system, and alternate site. The new septic system is located uphill from the home, where slopes are milder. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contours have been added to the site plan to show that stormwater drainage will not affect the septic system. The new trench will be constructed parallel to the slope where possible. The well on this lot is shown and any wells on the adjacent lots are not within 100’ of this lot. The new system will be at least 100 feet from all wells and surface water, and more than 5 feet from the septic tank. The alternate site is over 16 feet away. Please refer to the attached test hole logs, plan, and profile pages for the septic design. Following this design will prevent adverse impacts to adjacent properties.
