Anchorage, Alaska 99519 August 5,2011 Subject: Septic System Installation Permit Ladies and Gentlemen: I am writing to request a permit to upgrade the septic system for the above referenced property. The septic tank was replaced in 2004. A new deep trench drain field is proposed. 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 15.5 feet below ground surface (8/5/2011) Soil Rating. From Testhole 7/12/2011 5.3 min/in = 0.8 gal per sq.ft/day No. of Bedrooms 4 Required Area per Bedroom: 150/0.8 =188 sq.fi. Total area required: 188 x 4 = 752 sqfi System: We are proposing a deep trench absorption field connected to the existing septic tank The absorption field will be 80 feet long and 2 feet wide and contain 6.5 feet (1000 sq.ft, effective) of sewer rock. Soils: A test hole was excavated on July 12, 2011. See the attached soil logs. Ground water was monitored for through August 5,2011. Ground water was not observed in the test hole. The total depth of the test hole was 15.5 feet. We are proposing a maximum depth of our drain field to be 11.5 feet. A review of soils logs and well logs from neighboring properties show consistent soil horizons with what was observed in my soils analysis. No impermeable layers where noted to a depth of 20 feet. Surface Water: No surface waters were observed within one hundred feet of the proposed septic system. Topography: The lot rises slightly to the south west. Slopes do not exceed 5%. A elevation variation of 2-3 feet will exists over the length of the trench. Waivers: A lot line waiver will be required. The lot to the west is already developed and no 203 West 15th Avenue Suite 203, Anchorage, AK 99501, Phone: (907) 279-3916 Fax: (866) 354-1597, Lspurkland~gci. net Environmental Consulting and Design I adverse impacts are anticipated. We request a waiver to reduce this set back to 2 feet. The shape of the existing crib is irregular and determining its outer extents is not possible without substantial excavation. The proposed trench may encroach upon the 10 foot setback. We request a waiver to reduce this setback to 6 feet. No adverse impacts are anticipated in granting this waiver. 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, Civil Engineer 203 West 15th Avenue Suite 203, Anchorage, AK 99501, Phone: (907) 279-3916 Fax: (866) 354-1597, Lspurkland~gci.net Environmental Consulting and Design SEPTIC SYSTEM DESIGN Talus West Block 3 Lot 13 Municipality of Anchorage Development Services Department On Site Water and Wastewater Program 4700 Elmore Rd. Anchorage, Alaska 99519 August 18, 2011 Subject: Septic System Installation Permit 11866 Wilderness Drive Ladies and Gentlemen: I am writing to address several of the comments received from the Onsite Program after review the septic system installation permit for the above referenced property. 6. Ground water: Ground water was not observed during the excavation of the test hole. Current code requirements specify that the bottom of the proposed drain field be 4 feet above seasonal high ground water levels. Onsite Program has been requiring an additional 2 feet of vertical separation during the months of July and August to account for seasonal variations in ground water levels. To my knowledge Talus West S/D does not have a shallow ground water table. A review of test holes on neighboring properties appears to confirm this. A test hole excavated at Talus West Lot 14 Block 3 did not encounter ground water. The total depth of this test hole was 18 feet. 7. Bedrock: A review of test holes and well logs for the neighboring properties indicates that the depth to bed rock is over 150 feet. No impermeable layers are noted in the well logs for Talus West S/D Block 3 Lot 13, Block 4 Lot 3 and Block 3 Lot 20. Test holes on Block 3 Lot 14 and Block 4 Lot 3 were excavated to a depth of 18 feet. No impermeable layers were noted. 8. Percolation Test Location: Based upon the observed percolation rate, a minimum absorption area of 752 sq. feet is required. With an effective depth of 6.5 feet, the minimum trench length required is 58 feet. This entire area is within 30 feet of the test hole. 9. Drain Field Orientation: The ground surface rises 2-3 feet along south end the trench. The ground surface elevation is at the test hole is close to the low point of the trench. The proposed trench location will maintain the required separation from ground water and impermeable layers and will maintain a minimum of 4 feet of cover over the field. If you have any questions or concerns, please contact me at 279-3916.

A site plan and specifications are enclosed for your review. The original 32-year old tank has just collapsed so we are requesting an emergency replacement permit in order to install a new tank. Although the residence is 4-bedroom, the owners wish to install a 1500-gallon, Municipally approved septic tank. The topography of the lot in the area of proposed construction is generally level. The proposed project will have no significant impact on present or future water supply and wastewater disposal systems serving adjacent properties, nor will it have any significant impact on reserved space-surface and subsurface, or on drainage. Please give me a call at 345-1355 if you have any questions on this submittal. Sincerely, Ted Moore, P.E. INSTALL DBL. C.O.
