The existing undocumented septic system needs to be upgraded. The existing septic tank and drainfield will be decommissioned in accordance with the code. The proposed septic system will be located at the toe of a steep slope outside of the 100‐foot well radius. The proposed 5‐bedroom septic system upgrade is detailed on the design drawings. If constructed as designed, it will; Satisfy all code required separation distances, Not cause any probable adverse impacts to adjacent properties, Not negatively impact existing wells and septic systems on adjacent properties, Not be adversely affected by potential drainage that could flow onto and off of the subject property. Please feel free to contact me for more discussion. Thanks James Jay Crewdson, P.E.
