Box 196650 Anchorage, Alaska 99519-6650 Fax 249-7847 Re: Elmore #2 Subd. Blk 10, Lot 11 To Whom it may concern: This is a request for a new well and septic permit on the above referenced lot. The test hole consisted of poorly graded gravel (GP) for the entire 10 foot depth with water observed at 10 feet during the excavation and then raising to 7 feet after the 7 day monitoring period. The perc was two minutes per inch. The attached site plan has the new layout for the installation of a trench 65 feet long located to the west of the proposed driveway. None of the neighboring properties will be impacted by this upgrade since most are vacant and the lots are large. The slope at the site, is very flat, about 1 to 3 percent to the west. No cut banks or slopes over 25 percent existing with 200 feet of the proposed installation. Please call me if you have any questions. Sincerely J ~ Mic ae~l'N. AnderSon, P.E.
