Box 196650 Anchorage, AK 99519 On-Site Sewer Application Gentlemen: RECEIVED MAR 1 1 1994 Municipality of Anchorage Dept. Health & Human Sen/ices U.S. Survey 3202, Lot 2, T10N RIW S10 The attached paperwork presents EBA Engineering's on-site sewer design for the above referenced property. Design of the absorption field follows requirements specified in the Anchorage Municipal Code Chapter 15.65. A five foot wide shallow trench with a two foot effective depth has been specified. The minimum trench length is 55 feet and the maximum depth of the trench is six feet below the original ground surface. Reserve area for the lot is approximately 100,000 square feet. Slope on the tract is 30 to 35 percent on the south side of the property and 0 to 5 percent on the north side of the property. Slope in the immediate vicinity of the proposed drainfield site runs between 0 to 5 percent. Separation distances from the proposed system to all adjacent systems exceed 200 feet and impact on adjacent systems and property appears negligible. There is no surface water in the immediate vicinity of the drain field. The subsurface soils are primarily silty sands with gravel (SM) with a percolation rate of approximately 20 min/inch. Groundwater was not encountered in the drainfield area. The system installation will follow requirements specified in the Anchorage Municipal Code Chapter 15.65, and will be in accordance with On-Site Wastewater Disposal System Permit provisions. The following modifications have been made to EBA's initial on-site sewer design: 1. The calculation error has been corrected. Two 5' by 55' shallow trenches have been substituted for the original design. 2. Cleanout locations have been clearly delineated. 3. The total depth of the proposed bed has been illustrated. 907-East Dowling Road, Suite 27, Anchorage, Alaska 99518 · Telephone (907) 561-4085 · FAX (907) 561-7071 · 0941 0287 Page 2 4. The reserve replacement trench site has been moved an adequate distance from the 30 to 35% slope on the south side of the property.
