The change was made due to the slopes on the lot which exceed 10% in some cases. The developer of the lot is anxious to obtain a building permit for the lot and needs the septic system permit to do so. He is willing to provide additional soil tests and, if necessary, move the absorption trenches to a more suitable location at a later date. Weather conditions make additional exploration at this time very expensive. We have attempted to site the proposed absorption system near the location of the test hole placed during the initial subdivision of the parent parcel. A site visit yesterday indicates the location of the test hole is fairly fiat as noted on the test hole site plan provided by Hank Wilso.n.., I have also attached a contour map of the area completed during the initial subdivts~on by. Mr. Wilson. The location of the proposed absorption bed appears to meet the requirements of the Municipal Ordinance except that an additional percolation test will be required. We are confident that the soils on this lot are fairly uniform in that they vary from poody graded to well graded gravel. We will furnish additional soils information as required with the as-built of the new system. Thank you for your time concerning this issue and please call if you have additional questions. · ANDERSON ENGINEERING P.O.

Bragaw Street Anchorage, AK 99507 Attention: Dan Roth Su~e~: Lot 13, Block 2, Near Point Knoll Subdivision Permit No. SW010055 Dear Dan: The owner of Lot 13, Block 2, Near Point Knoll Subdivision has placed another test hole on a more suitable area of the lot for a septic system. A copy of the test hole log and percolation test is included for your review. This test hole was found to contain silty gravel with some sand which percolated at a rate approximating 2.5 minutes per'inch. No water was found in the test hole and none is expected during the monitoring period. An updated log will be forwarded to you once the 7 day monitoring period is completed. The attached revised site plan shows the location and configuration of the new trench. Based on conditions encountered the new trench will be 40' long by 3' wide with an effective depth of 7'. The owner has also decided to place a concrete slab on the south side of the lot for recreational vehicle parking. This site is also shown on the plan. Please review the attached documentation and revise Permit No. SW010055 to include the new design. Thank you for your cooperation with this modification. Sincerely, Michael E. Anderson, P.E.

The ~)wner of Lot 13, Block 2, Near Poi'nt K~oll Subdivision intends to place a new four- bedroom home on the lot. We are therefore applying for a permit to construct a new septic system on the lot to serve the' proposed home. The attached Site Plan and backup documentation identify the location and configuration of the new septic system and the parametem, used In the design. It also show. s the location of the alternate site and the water service line proposed for the lot. Ex~sfing drainage pattems are shown and will not be altered by th.e development of the lot. Several test holes we~.e' placed I~ this subdivision over the past years. All of these holes revealed'well to poorly graded gravels with percolation rates between 1 and 5' minutes per inch, A test hole at the proposed location for the new and alternate absorption trenches revealed poorly graded gravel with few fines and a percolation rate of less than-1 minute per inch. No groundwater was noted.in the'test hole dudng 'excavation and none was noted dudng the monitoring period, We are therefore 'proposing to place 2-5'.wide by 6.0.'.long by .5' effective depth absorption trenches with a 2' sand liner to slow the percolat~0n rate and effectively treat the septic effluent. The distribution pipe will be placed at 3' below the existing ground surface and the total depth of the trenches will be 5.5'.
