The parcel is currently being subdivided into two lots as shown on ~he attached drawing. We are therefore applying for a permit to construct a new well and septic system on the lot to serve the proposed home. The attached Site Plan and backup documentation identify the location and configuration of the new septic system and the parameters used in the design. Also identified on the plans are the location of the proposed well along with the test holes and the alternate site. Existing drainage patterns are shown and will not be altered by the development of the lot. We have surveyed the area and the new system will not conflict with other wells or septic systems in the area. Two test holes were recently placed on the lot to determine subsurface conditions. Soils were found to be poorly graded sands and gravel with varying amounts of silt. Percolation tests in the material indicated rates approximating 1 minute per inch in both the sand and the gravel. No groundwater was found during the excavation and none was found during the monitoring period. We are therefore proposing to place an absorption trench 32' long by 3' wide with a 6' effective depth to treat the septic effluent. The distribution pipe will be placed at 3' below the surface for a total depth of 9'. The ground surface on the lot slopes as shown on the attached Site Plan with grades from northwest to southeast and flatten in the area of the test holes. The new absorption trench will be constructed parallel to the contours of the surface as much as possible in conformance with Municipal requirements. Grading will be accomplished to assure surface drainage is away from the new trench. The existing drainage pattern on the lot will not be affected during development. If the system is constructed in accordance with our design the following statements apply: The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. BLM Lot 198, Section 18, T15N, R1W May 25, 2001 Page Two The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Michael E. Anderson, P.E.

Soils on the lot are very clean and the trench walls will not stand vertically during construction. The wider and shallower trench wilt be much easier to construct and require less drainfield rock. Please modify the septic system construction permit to allow the new configuration for the drainfield. Please let me know if you have any questions or additional information is required.

Work also includes the construction of a new 32' long X 3' wide X 6' effective depth absorption trench at the location shown. The distribution line in the trench will be placed at 3' below the existing ground surface. Total depth of the trench will be 9' below the existing ground surface. A minimum of 3' of cover are required above the absorption trench to protect against frost penetration. All components of the septic system must be placed a minimum of 100' from all wells in the area. Construction shall be in accordance with the approved site plan, design drawings, Municipal Permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. The Contractor shall be responsible for obtaining all underground utility locates and for the layout of the septic system and verification of the location of all lot lines. Unless specifically agreed otherwise, the contractor shall be responsible for final grading areas subsequently depressed from soil settling. Property owner shall be responsible for revegetation of affected areas unless specifically agreed otherwise. Contractors installing wastewater disposal systems must be certified by the Municipal Department of Health and Human Services for system installations. Owners installing their own systems must receive prior approval from D.H.H.S. before beginning system installation. SEPTIC TANK INSTALLATION 1. A new 1,000 gallon septic tank must be be procured from an approved source and installed at the location shown. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. 3. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 4. All standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 5. Tanks installed without 4' of cover shall have a minimum of 2" of direct burial insulation. ,BLM Lot 198, Section 18 May 26, 2001 Page 2 of 3 6. A foundation cleanout shall be installed one to four feet from the building foundation. Two cleanouts are required between the tank and the drainfield. 7. Final grading over the tank shall be such that a positive slope exists away from the septic tank. DRAINFIELD CONSTRUCTION: 2~ The drainfield shall be constructed to the dimensions shown on the design. The bottom of the trench shall be within 2" of level. Distribution piping must be placed level with perforations down atop a level bed of drainfield rock. Rock should then be placed over the pipe to provide a minimum of 2" of cover. A silt barrier or geotextile fabric must be placed between the drainfield rock and the natural soil backfill. 4. Monitor tubes must be 4" in diameter and installed at the locations shown on the design. The portion below ground must be perforated. Contractor shall verify the septic tank and drainfield are a minimum 100' away from any private water wells in the area, 150' from a Class "C" Well or 200' from any community well. Direct bury insulation must be placed over the distribution system if less than 3' of backfill depth is available. Finish grade over the trench must be mounded to prevent settlement or depressions. 7. Grade area surrounding the absorption trenches to drain away. o A minimum 2' of accepting soil is required below the drainfield rock for a 5' wide trench, Contractor shall verify this condition prior to placement of the rock. All pockets of unacceptable materials must be removed and replaced. MATERIAL SPECIFICATIONS: 1. Septic tanks must be constructed by a municipally approved septic tank manufacturer. The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: Cast Iron (perforated and solid), ASTM D3034 or P.V.C. (perforated and solid), ASTM F810 or H.D.P.E. (perforated, but not solid) and ASTM D2662 or A.B.S. (perforated and solid). Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Co. Styrofoam HI or equal). Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). · .BLM Lot 198, Section 18 May 26, 2001 Page 3 of 3 5. A permeable geotextile fabric (Typar, Mirafi or equal) must be installed between the final 'drain rock layer and the native soil layer. 6. All drain rock shall be .5" to 2.5" in diameter with less than 3% passing the #200 sieve. INSPECTIONS: Municipal Ordinance requires a minimum of two inspections. These inspections must be conducted under the supervision of a professional engineer registered in the State of Alaska. The first inspection must be conducted after the excavation of trenches, beds or pits and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled. The second inspection must be conducted after the placement of the geotextile fabric, gravel, distribution piping, standpipes, cleanouts and insulation. No backfill should be in place at the time of inspection. Contractor shall provide a copy of all field survey layout and construction notes for use in preparing the certified as-built of the completed system.
