Box 196650 Anchorage, Alaska 99519-6650 Ref.: New Sewer & Water System Design and Permit Application Fairmount Subdivision, Add. A, Lot 24 Gentlemen: The owner of the above referenced property wishes to construct a new 5-bedrcom single family residence. The property will be served by on-site septic and water. The attached documents include a proposed septic system design and depicts the location of the proposed well and septic on the lot. SEPTIC SYSTEM - Design Details SUBSURFACE CONDITIONS: Attached are soil logs for two test pits excavated on the property for the purpose of characterizing the subsurface conditions. Percolation test results are shown on the logs. Ground water was encountered in both excavations. The water level was measured after being allowed to stabilize for eight days from the date of the excavation. This final elevation is also shown on the soil logs. 2. DESIGN SUMMARY: a. System type: Absorption bed b. Percolation rate: less than I minute per inch. c. Application rate: 0.7 gpd/sf for Fdter sand. d. Design flow: 5 bdrms x 150 gpd fodrm = 750 gpd e. Min. absorption area: 600 ~/0.7 gpd/sf = 1071 sf f. Width: 15 ft g. Length: 71.5 ft h. Sand f'dterdepth: 24 inches. SKLH Consultants / MOA On-Site Services New SAS; Fairmount, Add. A Lot 24 July 31.1, 2000 Page 2 of 2 SURFACE WATER: The North and South property lines are bounded by two creeks. To the North lies the Little Rabbit Creek and to the South is a small (less than 2 feet across and 4 inches deep) creek in the Ricky Road ROW. The minimum 100-ft protective separation distance for both creeks have been shown on the attached sheets. TOPOGRAPHY: The lot has a steady slope to the West and Northwest of between 4 and 8 percent. A steep slope exists along the Little Rabbit Creek with an estimated vertical elevation difference of over 25 feet. The slope is substantially greater than 25%, but is of no significance since locating the septic system is over shadowed by the new water well and the creek set back distances. To the best of my knowledge, the proposed installation does not adversely impact the development of adjacent lots. If you should have questions, please do not hesitate to contact me.
