The lot has an existing well that the owner intends to use but the existing crib and tank have been abandoned. The exact location of the abandoned septic is unknown. Due to the amount of available space, we are proposing a Category III system. The attached site plan identifies the location of the home as well as the proposed 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 towards the southwest between 25-35%. The new septic system will be located towards the west side of the lot on slopes between 20-30%. There are no slopes greater than 46% within 50 feet downslope of either the primary or alternate site. The current design meets all steep slope provisions as stated in 15.65.210.B.4 of the MOA Wastewater Code. Contour lines 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. Well radii that conflict with this property are shown. The new system will be greater than 50’ from all wells and surface water, and more than 5’ away from the septic tank. The alternate site is located more than 6’ away from the primary site. Please refer to the attached test hole log and plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
