B~ 102954 Anchorage, Alaska, 99510 Subject: Lot 13, Block H Knik Heights Subdiv/sion Well and Septic Permit Gentlemen: My firm was contacted to investigate the possibility of installing of a new system at the above referenced property. Currently the lot is undeveloped. A single test hole was excavated on January 8, 2000. The soil report and percolation test results are attached. Ground water was monitored for seven days. No ground water was encountered or monitored. No bedrock was encountered in the test hole. The lot is approximately 1.2 acres in size. Lot 13 slopes to the west at a rate of approximately 8 to 14 percent The proposed installation will be located in the center of the lot on a flat bench The proposed location will be greater than 100 feet away from the proposed well serving this property and 25 feet from the water service lines. The surrounding systems are located greater than 200 feet from the proposed installation, the lots to the north, south and east are developed, but do not conflict with the proposed installation. The proposed installation shall not impact the future development of the surrounding or existing lots. See attached design. The new system will maintain over six feet vertical separation to the bedrock and over four feet vertically to the ground water. The mwner is an experienced excavator, and plans to install the system himself. Please contact me at 272-8218, or 227-3522 if you have any questions. Sincerely, C:~WORK~ I-MARG.~I ]]EglGN P.Z.o.

Well Manhole—The well manhole was installed over well compacted Type IIA material and a 1- %" flexible drain pipe was installed from the manhole floor to the 4" foundation drain on the house. The foundation drain daylights on the Southwest corner of the house in the grove of spruce trees to the right of the driveway. The concrete surrounding the manhole is 5" thick with rebar and woven wire mesh with 4" of rigid foam insulation just under the concrete. The entire slab is heated. The lid for the manhole is the highest point (the concrete slopes away from the manhole) and has a full rubber gasket. We have never had any issues with water entering into the manhole in the +-22 years we have been in the home. 2. Septic System —The parking area over the septic system has generally existed since we built the home. The septic has never frozen in those +-22 years. There have been no frost issues with the septic system. I will forward pictures of the large boulders when they are placed around the septic tank. I hope this addresses the concerns raised.

July 27, 2022 Municipality of Anchorage COSA Re: 13001 Ridgewood Road COSA 2022 To Whom It May Concern, I was asked by Brent Western of First Water to address some concerns raised about our well and septic. 1. Well Manhole —The well manhole was installed over well compacted Type IIA material and a 1- %" flexible drain pipe was installed from the manhole floor to the 4" foundation drain on the house. The foundation drain daylights on the Southwest corner of the house in the grove of spruce trees to the right of the driveway. The concrete surrounding the manhole is 5" thick with rebar and woven wire mesh with 4" of rigid foam insulation just under the concrete. The entire slab is heated. The lid for the manhole is the highest point (the concrete slopes away from the manhole) and has a full rubber gasket. We have never had any issues with water entering into the manhole in the +-22 years we have been in the home. 2. Septic System —The parking area over the septic system has generally existed since we built the home. The septic has never frozen in those +-22 years. There have been no frost issues with the septic system. I will forward pictures of the large boulders when they are placed around the septic tank. I hope this addresses the concerns raised. Thank you. Jason M.
