The vertical separation distances were measured from the up-gradient side of the field, the trench does not exceed 60” wide, and the pipe invert is 3’ below the original grade. Any disturbed vegetation within 50’ downhill has been restored with erosion control vegetation. The proposed design meets all MOA steep slope requirements as stated in AMC 15.65.210.B.4. Sincerely, Benjamin Schiller, PE 9/24/21 October 7, 2021 MOA Development Services Department On -Site Water & Wastewater Program 4700 Elmore Rd Anchorage, AK 99507 Subject: Shangri-La Estates East, Block 1, Lot 14 — NHN Sandpiper Drive Test hole justification Dear On -Site Services Engineer: During construction, on this property, the trench was installed outside the 30' radius of a test hole. However, after comparing the test holes performed by Forge Engineering in 2020 to the subdivision test hole dug on the south side of the property in 2006, we are confident that the soil in the location of the existing trench is either identical to or better than the soils encountered in the test holes used for this design. The subdivision test hole log shows a percolation rate of 1.6 MPI and no groundwater in the month of May down to 16'. Please see the aforementioned test hole log attached for reference.

We are submitting this permit application for the construction of a new well and septic system. The attached site plan identifies the location of the home and the proposed well and 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 in the area of the absorption trenches slope slightly to the north. Slopes greater than 25% may be found less than 35’ from the trenches, but the total drop between the distribution line in the trench and the base of the slope is less than 10’. Surface contours are shown on the site plan indicating the grade and direction of flow. Storm water drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. 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. Please refer to the attached test hole log and plan and profile sheets for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
