This design is for a new pressure distr consisting of a septic tank, with lift station feedin trench absorption field. Jeep 2. The existing lot has ample soils to install the original trench with two reserve areas, but needs additional fill along the bluff line to provide a minimum of 50' from the field to the top of bluff. To allow the excess fill material on the site to be used for this bluff filling, the fill work will be accomplished no later than the installation of the field. The contractor is responsible for obtaining any fill permits for this installation. 3. System Design -- 4 bedrooms at 188 sf/bedroom = 752 sf area Trench system -- 58' length x 7' depth x 2 = 812 sf, therefore the trench meets the system size criteria. 4. All construction materials, construction methods and electrical and on-site inspections will follow MOA rules and regulations. The electrical inspection for the lift station shall follow MOA code requirements for both installation and inspections. The contractor is responsible for obtaining all required electrical permits. The contractor is responsible for notifying the Engineer and the MOA at least four hours in advance of all inspection needs. The contractor will insure that no additions or changes have been made to the location of adjacent wells or septic systems prior to the start of construction. If any changes to those systems have occurred, the Engineer should be immediately notified for review and possible changes. 5. The 1 1/4" field pipe will be placed no higher than the top of the SM material. 6. The lot has a small flat top area above the bluff line. The remainder of the site slopes down at 40 - 50% to the north. The new system is over 200 feet from the creek located near the north property line. With the filling of the bluff area this system will have little or no effect on surface drainage, ground water levels or the adjacent systems in the area. The top of field pipe is designed to be below the street ditch grade to prevent contamination from the system to the drainage ditch. 7. The system should be maintained with annual pumping and inspection of the tank and lift station components. The alarm system for the lift station high water level should be located in the house in accordance with MOA requirements. ON-SITE WASTEWATER SYSTEM DESIGN LIFT STATION DESIGN CRITERIA Lot 9 & 10, Clearview subdivision The lift station will be approved by the Municipality of Anchorage, Department of Health and Human Services prior to construction.

FROM: Susan Oswalt, On-site Services /~ . Department of Health and Human~ervices SUBJECT: Request for Comments on Subdivisions August 30, 1991 The Environmental Services Division, On-site Services Section, of the Department of Health and Human Services has reviewed the following cases and has these comments: S-9114: Lot 9A Clearview Subdivision We recommend this plat be denied. Currently neither lot can meet technical requirements for on-site wastewater permits under ~34C 15.65 due to the lack of reserved disposal areas and the steep slopes requiring setbacks. Even in combination, these lots lack the required amount of area less than 25% slope and required distance from lot lines, drainages, and edge of slope. There is no information on water availability. S-9115: S-9116: S-9117: Lot lB Moorehand Subdivision Provide copy of ADEC Certificate to operate a public well prior to final approval. Lots 9A, 9B Block 10 Fist Addition Alaska Industrial Subdivision Both lots must be served by public sewer and water. Lots 4A, 4B Block 9 Prospect Heights Snbdivision The original soil test was performed in 1977; there is no monitoring tube for verification of groundwater table. We request that a new tube be installed, and monitoring be performed through a high water period. We require information on water availability. The applicant has failed to provide information on wells and wastewater disposal systems within 200 feet of the development. We also require that the applicant show which provision for reserved disposal area will be utilized.
