Box 196650 Anchorage, AK 99519-6650 Re: ON-SITE SEWER/WELL PERMIT Dear Sirs: RECEIVED At the request of Mary Britton, Phukan Consulting Engineers & Associates, Inc. (PCA) performed a preliminary investigation at the property with the legal description of Lot 11, Block 9, Second Addition to Elmore Subdivision. The purpose ofthe investigation was to determine the suitability of the subject property for development and on-site wastewater disposal. Two test pits were dug at the property. Their locations are shown on the enclosed site plan. Both test pits revealed an organic mat to an eight inch depth underlain by sandy silt from eight inches to 33 inches below the existing ground surface. Below the sandy silt, from 33 inches to eight feet deep is sandy gravel with cobbles. Ground water table was encountered at about seven foot depth in both test holes. Ground water was then monitored at both locations from September 14 through October 18, 1996. (Ref. attached Table). The highest water level was observed October 16 at Test Hole # 1, where the water level was 73.5 inches below the existing ground surface. A percolation test was conducted eight feet east of Test Hole # l, at a depth of four feet within the sandy gravel layer. Test results indicated a percolation rate of 3.5 minutes per inch. (Ref. attached test results). This is consistent with the visual soil classification and observed percolation rates on neighboring lots. Based on thc field investigation results, a five foot wide standard shallow trench disposal system has been designed for the leach field. To insure a four foot separation distance to ground water table, the base of the trench will be two feet below grade. The sandy silt at this level will be removed and replaced with filter sand. The trench was sized for the proposed three-bedroom house using an infiltration rate of one gallon per day per square foot, and an application rate of 150 gallonspcr bedroom per day. A total infiltration area of 450 square feet is proposed. There is minimal probable impact from the proposed wastewater disposal system to adjacent property. Wells are over 200 feet away from and up gradient of the proposed absorption trench and will not be affected. Existing wastewater systems are over 100 feet 2702 Gambell, Suite 201 · Anchorage, Alaska 99503 · (907) 272-7111 I FAX 277-3177 Department of Health and ttuman Services November 22, 1996 · Page 2 away and also, will not be impacted. Reserved space and drainage on adjacent lots will not be affected. It is concluded and recommended that the proposed wastewater disposal system when constructed in accordance with the enclosed drawings and specifications, will not adversely affect ground or surface water quality or punic health. As such, permit should be given for the construction of the proposed septic system and a water well at the property as indicated. Should you have any questions, please do not hesitate to contact us.
