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 slopes gradually toward the south. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate s ite. There are contour lines, labeled with elevations, on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trenches will be constructed parallel to the slope as much as possible. Wells on this and adjacent lots are shown along with the neighboring wastewater systems. 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 logs, plan, and profile pages for the septic design. A confirmation test hole will be performed to confirm the findings of the subdivision test hole used for the permit application. If this design is followed, there will be no adverse impacts to adjacent properties.

The minimum well productivity required by this Department (AMC 15.55) for a 4 -bedroom residence is .42 gallons per minute. Although the subject well currently exceeds this minimum requirement, all parties concerned are advised that the production capacity of the well may fluctuate. Restriction of non-critical water uses such as washing cars and watering lawns and gardens may be required. This advisory must be attached to all copies of the subject Certificate of On - Site Systems Approval.
