We are submitting this permit application for a new system. The property currently has a home, a cabin with a bathroom, a well, and several septic pipes in the back yard. We are unable to detennine from these pipes the layout of the existing septic disposal field. The new system will accommodate the 3 -bedroom home in addition to the cabin. The ground surface on the lot slopes down toward the northwest corner of the lot between 5-8% slopes. There are no slopes greater than 25% within 50 feet downslope of the system. Drainage arrows are shown 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. Due to the time constraints with the home being for sale, we are proposing to use adjacent test hole information for the design and dig a confirmation test hole before installation. We have collected test hole information for all of the surrounding lots, compiled into the following table. The percolation rates varied, but were consistently more than 15 min/in, with the longest rates over 40 and 50 min/in. Our proposed design assumes a percolation rate between 30-60 min/in. Almost every test hole documented no groundwater with the exception of a test hole on Rons Lot 2, which indicated groundwater at "10+ feet". This seems to be, not an actual measured level, but instead documentation that the subsequent trench design had "at least" enough separation to meet code. We will be digging a confirmation test hole on-site prior to installation. Our trench section assumes that in this new test hole we will confirm a groundwater reading of at least 12' to the seasonal high, and 14' to bedrock/impermeable layers.
