The septic system serving the home has reached the end of its useful life, so we are submitting this permit application for the construction of a new and septic system. The attached site plan identifies the location of the home as well as the proposed septic location. 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 north east to the south west at a moderate slope of around 10%-15% across most of the lot. While the corners of the lot do approach 25% slope, there are no slopes greater than 25% within 50 feet downslope of the proposed septic system. 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. The size of the lot, direction of the contours, location of existing structures, and the existing drainfield limit the available area for a new drainfield. As a result, the proposed drainfield must be located within 10 feet of the north property line. There are no structures within 10 feet of the property line, and the proposed drainfield will have no adverse impact on the neighboring property. For these reasons, we request a waiver to allow the drainfield to be 5’ from the property line. Wells on this and adjacent lots are shown. The new system will be a minimum of 100’ from all wells and surface water, and more than 5’ away from the septic tank. Please refer to the attached test hole log, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

Street Anchorage, Alaska 99501 { nUIROrlmErITAL COFITROL SI RUICI B, IrlC. Dear Susan: This is in regards to Northwoods Subdivision Phase IV, Block 16, Lots 16 & 17. In the spring of 1985, I performed soils tests on each of these lots. There also had been a testhole done in February 1984 on lot 16 to 13 feet that was dry. On May 17, 1985, I inspected septic systems installed on both lots. On Lot 16 they installed a deep trench and on Lot 17 a shallow bed. Both systems were bone dry. These soil logs and inspection reports are enclosed. Recently, however, there have been some groundwater problems with various lots in Northwoods. So, before granting final approval for the Health Authority Approval on these lots, the MOA requested that testholes be dug near the septic systems in order to determine whether or not groundwater had come up in this area subsequent to the inspection. Therefore, four testholes were performed, with monitor tubes installed in all. A drawing is attached showing the location of these testholes. On Lot 17, two test holes were performed. One was done about 20 feet south of the bed, towards the road. This test hole was dug to 12 feet on 10/22/85 and originally was dry. On 10/29 the water had seeped in to a depth of 7.5 feet, and on 11/6/85 it was stabilized at 7.5 feet. This testhole was done near the shallowest corner of the bed, where the original depth of the bed was only about 3 feet (See inspection report -- top of tile to finish grade was only 2 feet here.) Further, groundlevel at the monitor test location is about a foot lower than at the bed, so even if the 7.5 fooC water table were continuous laterally, it would be 4.5 feet below the base of the bed. However, a second testhole was done near this bed to the east, 16 feet from the bed, and here seeps that were at 14.8 feet on 10/29 stabilized at 11.7 feet on 11/6, well below the level of the bed. Therefore, it does not appear that groundwater is in any danger of being contaminated by the bed on Lot 17. The standpipes in the bed also proved to have no water in them. On Lot 16, a trench 11 feet deep was dug for the septic systems~ A testhole was dug about 40 feet south of this trench, in.which some seeps from 8 to 12.5 feet were observed yon 10/22 which were at 9 feet on 10/29 and 8.7 feet on 11/6. ~y However, 40 feet is really quite far away from'the septic system, so a second test hole was du~ only 10. feet from the 1200 LUesI 33rd Aucnu~, Suile E; o Anchora§e, /~l~sk~ 99503-(907) 561-50z10 trench, and it was dry to a depth of 15 feet on 10/29 and still dry on 11/6. The standpipe in' the trench also is dry. Therefore, it appears that groundwater on Lot 16 also is in no danger of being contaminated by the septic system. Now, you may have noticed by the drawing that Test Hole #4, with water stabilized at 11.7 feet, is only 22 feet from this ll-foot deep trench. However, this is no cause for alarm. It is obvious that Test Hole #4 does not represent the true, laterially continuous water table; otherwise, one would certainly expect to find groundwater also around I1 feet at Test Hole #3, which is only about 30 feet away and downhill. Yet Test Hole #3 is dry to 15 feet. It appears that an isolated seep, possibly a misplaced pocket of water, was encountered at Test Hole #4 which does not go anywhere near the septic systems. Therefore, since the original soils tests were dry, the original inspections weredry, and the recently dug test holes show groundwater to be at i~ast 4 feet below the bottom of either septic system, we feel there is now'no reason to withhold final approval of the Health Authority Approval for either of these two lots. If you have any questions please feel free to call. Sincerely, Darcy ~'evens Engineering Geologist
