We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. Also identified on the plans are the locations of wells and septic systems on the surrounding lots. No conflicts exist between the proposed septic system and those on adjacent lots. Drainage arrows are shown indicating the surface slope of the property in the area of the new septic system. Test holes were placed on the lot in the area of the absorption trench and alternate site, which indicated a silty sand with some gravel (SM/SP) material.. The percolation rate of the materials was determined to be 17 to 60 minutes per inch. No groundwater was found during the placement of the test holes, but was noted at 13' and 14' during the monitoring period. An application rate of .45 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,250 -gallon septic tank and 2-56' long by 3' wide by 6' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 2' below the surface and the total depth will be 8'. A minimum of 3' of fill will be placed over the absorption trenches and 4' over the septic tank. A flow splitter valve will be installed to insure even flow to each trench. The ground surface on the lot in the area of the septic system slopes gently to the northwest. The new trenches will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from all wells and any surface water and 10' the Lot 4, Sandy Acres November 17, 2005 Page Two proposed and existing water services in the area. If the system is constructed in accordance with our design the following statements apply: 1. 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. 2. 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. 3. 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. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, n� " OW'4 , 4f GCa•dc- Michael E.

Tanks installed without 4' of cover shall have a minimum of 2" of direct burial insulation. 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: 1. The drainfield shall be constructed to the dimensions shown on the design. The bottom of the trench shall be within 2" of level. 2. 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. 3. 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. 5. 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. 6. 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 trench to drain away. 8. 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. Lot 4, Sandy Acres November 17, 2005 Page 3 of 3 MATERIAL SPECIFICATIONS: Septic tanks must be constructed by a municipally approved septic tank manufacturer. 2. 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). 3. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Co. Styrofoam HI or equal). 4. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). 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. ANDERSON ENGINEERING P.O. BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 FAX MEMORANDUM DATE: November 30, 2005 TO: Julie Makela, P.E. FROM: Mike Anderson, P.E. SUBJECT: Lot 4, Sandy Acres Subdivision Well and Septic System Permit Attached ;is the modified area map showing wells and septic systems surrounding Lot 4, Sandy Acres Subdivision. A Class A Well is in service on the property immediately to the west. The well is located more than 200' from the property lines of Lot 4. No other wells or septic systems in the area conflict with the proposed well or septic system for this lot. The proposed absorption trench system and alternate site are located slightly outside the 30' radius of the test hole on the lot. This test hole was completed during the subdivision phase of the project and was the only area where soil absorption characteristics were slower than 15 minutes per inch. We anticipate that actual conditions found surrounding this test hole will yield soils with much better absorptive characteristics. We therefore request that a condition be placed on the permit requiring the submittal of an additional test hole and percolation testing to verify soil conditions. This work can be accomplished at the time of the construction of the system and will result in a substantial monetary saving to the owner of the property.
