The proposed system will serve a future 4-bedroom single-family residence. Soil logs, design calculations, site plan and design drawings are enclosed for your review. L. Soils. In May 2022 a test hole was dug to a depth of t2'.In June no groundwater presented itself in the test hole. The adjusted seasonalgroundwater elevation for the month of June would be 11'. The percolation rate was < 1 mpi. 2. Soil Absorption System Design. See Sheet 2 of the design package. 3. Wells. A new private water well will be drilled on this lot. Neighboring properties are served by private water wells. All neighboring water wells are > 100' from the subject property septic system. 4. Neighboring Wastewater systems. lmmediate neighboring septic systems are all +10' distant from the property lines. 5. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field. 5. Topography: The property in the immediate area of the new trench has a slope of 32%. ' The criteria of 15.65.210 B.1.d can't be met, as the field draining the house is less than 50' up-gradient from the 32% slope. The 'steep slope' provisions of this code will apply. Construction of the septic system will meet all the conditions of L5.65.210 B.4.a i, ii, iv. 15.65.210 B.4.a iii will apply to this case and all existing vegetation on the 32% slope will remain intact. The slopes will not be disturbed. 15.65.210 B.4.a.v The disposal field is greater than 100' up-gradient from any 46% slope. As shown on sheet 4 of the design package, a line of 46% slope starting at 2.5' above the invert of the perforated pipe does not daylight the existing ground for at least 35'. The proposed installation will not affect the future development of this or the surrounding lots. Sincerely, Curtis L. Townsend, P.E.
