The attached site plan identifies the location of the home as well as the proposed well, septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system, whether on this lot or adjacent lots. The ground surface on the lot slopes down from the east side of the lot to the west side of the lot at between 10-20% slopes. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contours are shown on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. During the excavation of the test hole, groundwater came up too fast for us to do a perk test on the soils under the organic layer. For that reason, we took a sample of the soil to the lab for an analysis. The soils were classified as SM, “Silty sand w/ gravel”. It was close to 50% sand and less than 21% silt, and would not be impermeable. We would anticipate this soil to have a percolation rate under 60 min/in. However, we have designed this with a conservative perk rate of 6 1-90 min/in. Test holes in adjacent properties were found to have the following perk rates: Municipality of Anchorage On-site Water and Wastewater REVIEWED FOR CODE COMPLIANCE OSP241316, Deb Wockenfuss, 09/23/24 Test Hole Soil Perk rate Lot 9, 7/28/00 SM, Silty Sand 3.2 min/in Lot 9, 7/28/00 GM, Silty Gravel 4.4 min/in Lot 11, 3/20/91 SP, Poorly graded sand 13 min/in B4 Lot 8, 3/22/01 GM, Silty Gravel 24 min/in B4 Lot 8, 3/22/01 GM, Silty Gravel 24 min/in B4 Lot 9, 4/14/92 GM, Silty Gravel 3 min/in B4 Lot 9, 4/14/92 GM, Silty Gravel 33 min/in As there is no way to percolate these soils, we ask that this conservative rate be accepted in lieu of a stamped perk test. Wells on this and adjacent lots are shown. The new system will be a minimum of 50’ from all wells and surface water, and more than 5’ away from the septic tank. The alternate site is located more than 6’ away. Please refer to the attached test hole log, lab analysis, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
