BOX 196650 Anchorage, Alaska 99519-6650 August 4, 1992 Mrs. Delores Widmer 5901 East Sixth Ave. #233 Anchorage, AK 99504 Subject: Lot 15, Blk 1, Birchtree Est. PID #017-141-23 Dear Mrs. Widmer, A careful review of the permit application for the subject lot has shown that the soil conditions do not meet the minimum requirements for on site wastewater disposal. As set forth in AMC 15.65, the lack of sufficient permeable soil and the presence of seasonally high groundwater prohibit development of a conventional soil absorption system. An appeal of this decision may be made through the office of the director pursuant to AMC 15.05.090 and AMC 15.65.015. Please be advised that any appeal must be made within twenty (20) days of the date of this decision. If you wish to discuss the matter further please do not hesitate to contact my office at 343-4744.

This investigation was perfo'L~med in accordance with your req-aest of July 28, 1975, and those pro- cedures outlined in a letter dated July 15, 1975 by Mr. Roll Strickland of the Greater Anchorage Area Borough Department of Environmental Quality. A'single test hole was put down within Lot 15, Block 1 of Birch Tree Estates S~.~bdivision for-the purpose of defining general subsurface soil conditions L©r the proposed sanitary system. Excavation was accomplished with a hand powered post hole digger. The test hole was extended to a hotal depth of 6.5 feet below ground surface. The material encountered was found to consist of 4 inches of organics over- lying 3 feet of clayey Silt with some sand and trace gravel grading to clayey sandy silt with some gravel.
