We are submitting this permit application for the construction of a new well and septic system to serve the home. 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 is virtually flat. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. 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. The absorption trench will be constructed utilizing engineered receiving soils in conformance with Section 15.65.210D3c and the attached design documents. The absorption trench will be utilized in association with an Advantex Treatment System with an AX-20 pod and pump vault. The system will be 50’ from the well on this and adjacent lots. The percolation rate for the accepting soils was estimated based on the silt content of the material found at that location. The silt content was determined to be 33.5% with 41.5% sand and 25.0% gravel. This resulted in a USCS Classification of SM or silty sand. Past experience has shown this material to absorb water at between 30 and 60 minutes per inch and often faster depending on in situ density. Please refer to the attached test hole logs, soils lab analysis, plan and profile sheets for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
