Morris Department of Health and Human Services Municipality of Anchorage 825 L Street Anchorage, AK 99501 Re: Proposed Holding Tank Lot 5 Blk 1 Valhalla Subdivision. Dear Mr. Morris: I completed to test holes on the subject lot on May 21, 1987 and found the existing soil to be unacceptable for placement of a drainfield, mound system or a bed system. The soil is organics overlaying a very silty sand (hard pan). Water was encountered at 5.5 feet in Test Hole #1 and 3.0 feet in Test Hole ~2. I cannot find a place on the lot whore an onsite system could be placed without encountering some physical conflict or poor soil conditions. My reco~aendation is to use a holding tank. At this point, I see no other option. After discussion with the owner, Marlene Swift, a 4,000 gallon holding tank has been selected. The holding tank will be placed directly in line with the septic ta~ and 5 feet west of the septic tank. The septic tank will remain in service with effluent flowing into the holding tank after primary settling in the septic tank. (see attached sketch) A flow level indicator (alarm) allowing 48 hours storage will be installed. I am also attaching the soil logs for the two test holes.

Our walk-through inspections of the septic system on the subject property indicate that the system is in a state of failure. On April 17 sewage discharge was observed on the ground near the septic tank standpipe. The tank was pumped a few days later. Approximately three weeks later the septic system was again inspected. Although there was no evidence of recent overflow, fluid levels in the standpipe were near ground level indicating that overflow was imminent. The tank and absorption field should be pumped immediately to prevent further sewage overflow. These observations indicate that the septic system has failed. Please contact one of the engineers on the list provided. The engineer should be able to provide you with some options to remedy this problem. Normally the engineering work required to investigate the cause of septic system failure and obtain an on-site permit takes less than two weeks. Thank you for your cooperation in this matter. If this Department can be of any assistance regarding the upgrade of your system please let us know. Your prompt attention to the matter of upgrading this failing septic system will be appreciated.

Anchorage, Alaska Dear Mro Wiese: We are submitting herewith the test boring results and our comments regarding soil co~d~tions encountered at the subject site. This investigation was performed Jn accordance with your request of February 17, 1977 and those procedures outlined in a letter dated July 15, 1975, by Mr. Roll Stick]and of the Municipality of Anchorage, Departmeat of Environmental Quality. A single test hole was bored on each lot within the subject area for the ?urpose of defining genera] subsurface soil conditions for the proposed sanitary systems. Excavation was accomplished with an auger type drilling rig and each test hole was extended to a total depth of 20 feet below grou~ld surface. The final logs prepared for the test holes have been included ~n Drawing A-.02. Groundwater was encountered in each test hole while drilling. III Test Hole 1, groundwater was encountered at 13 feet. In Test Hole 2, groundwater was encountered at 14 feet below ground surface. A percolation test was performed from a depth indicated and reflects average infiltration from that depth to the bottom of the hole. We appreciate being given this opportunity to be of service to you. Should you have any questions with regard to the above, please do not hesitate to contact us.
