The attached site plan identifies the location of the home and the proposed septic system. There are no conflicts with any other well or septic system on this lot or adjacent lots. The lot is generally flat, and the septic system is located in the flattest area. There are no slopes greater than 25% within 50 feet downslope of the site. Contours on the site plan show grade and flow direction. Stormwater drainage will not impact the system, and the trench will be constructed parallel to the slope. The well on this lot is shown. Wells on adjacent lots are not within viewing distance. The septic system will be a minimum of 100’ from all wells and surface water, and more than 5’ from the septic tank. Please refer to the attached test hole log, plan, and profile pages for the septic design. Following this design will ensure no adverse impacts to adjacent properties.
