The proposed system will serve a 3-bedroom single-family residence. The existing system was installed in 1982 and did not meet COSA operation requirements. Soil logs, design calculations, a site plan, design drawings and construction specifications are enclosed for your review. Design Calcs: No Groundwater observed to a depth of 18 feet below ground surface (10/1/2010) Soil Rating. From Testhole 9/24/2010 1 min/in = Maximum application rate 1.2 gal per sq.ft/day No. of Bedrooms 3 Required Area per Bedroom: 150/1.2 gpd/sq.ft.= 125 sq.ft. Total area required: 125 x 3 = 375 sq.ft. System: We are proposing a 1000 gallon septic tank, and a deep trench absorption field. The absorption field will be 40 feet long and 2.5 feet wide and contain 6 feet of sewer rock. This provides 480 sq. feet. of effective absorption area. Soils: A test hole was excavated on September 24, 2010. See the attached soil logs. Ground water was monitored for through October 1, 2010. Ground water was not observed. A percolation test was conducted at a depth of 5 feet in the limiting stata (1 min./in). The gravely sand from 1-4 will perc at a faster rate. The drain field was sized using conservative application rate of 1.0 g.p.d./sq.ft. 203 West 15th Avenue Suite 203, Anchorage, AK 99501, Phone: (907) 279-3916 Fax: (866) 354-1597, Lspurkland~gci.net Surface Water: system upgrade. Environmental Consulting and Design I There are no surface waters within several hundred feet of the proposed septic Topography: The lot slopes from the northeast to the south west at approximately 20-30%. The existing trench has been located above this slope for 28 years and there is no indication of effluent seeping out anywhere down grade of the trench. The entire area is heavily vegetated and in our opinion the day lighting of septic system effluent is not a concern. Waivers: Slope set back waiver 35 feet- drain field to slope greater than 25%. The installation of this septic system will not prevent wells and septic systems from being installed on the adjacent lots. The proposed septic system will not change the general slope of the area. Ponding and/or concentration of surface runoff will not result from this installation. If you have any questions or concerns, please contact me at 279-3916. Sincerely, Lars Spurkland, P.E.
