Septic System Design Dear On-Site Services Engineer: The owner of the above lot intends to build a 4-bedroom home on the property. We are submitting this permit application for the construction of a new well and septic system. The attached site plan identifies the location of the home and the proposed well, septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system on this lot or adjacent lots. The ground surface on the lot slopes gently to the southwest at grades approximating 20%. There are slopes greater than 25% within 50 feet downslope of the absorption trenches, but the trenches are designed to meet the steep slope provisions of the ordinance 15.65.210.4a and no waiver is required. Ground surface contours are shown on the site plan indicating 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. The new system will be a minimum of 100’ from all wells and surface water, and more than 5’ away from the septic tank. Please refer to the attached test hole log and plan and profile sheets for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
