ANDERSON ENGINEERING P.O.

We are therefore requesting a permit be issued for the construction of a septic system to accommodate the home. The subdivision is currently served by the AWWU water system. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system along with the alternate site. Also identified on the plans are the locations of the proposed water service line. 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 1 to 5 minutes per inch. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. An application rate of 1.2 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 2,000 -gallon septic tank and a 54' long by 3' wide by 7' effective depth absorption trench to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 3' below the surface and the total depth will be 10'. A minimum of 3' of fill will be placed over the absorption trenches and 4' over the septic tank. 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 Lot 5, Block 1, Sky Hills November 8, 2005 Page Two constructed a minimum of 100' from any surface water and 10' the 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, A s rIAC" Michael E. Anderson, P.E.

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 8, Block 1, Sky Hills November 8, 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.

BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 FAX MEMORANDUM DATE: December 12, 2006 TO: Deb Wockenfuss FROM: Mike Anderson, P.E. SUBJECT: Lot 5, Block 1, Skyhills Subdivision No. 1 Septic System As Built The septic system absorption trench orientation for the subject lot was designed based on drainage patterns shown on the surveyor's certified plot plan. A copy of that plan is attached for your review. The contractor elected to change the configuration of the trenches based on actual conditions encountered in the field. The surface area at the location of the trench is virtually flat and either orientation is acceptable. We have paid the $115 Septic System Exception Fee. Test holes were placed on the lot prior to any clearing and were located with a cloth tape prior to the flagging of the lot lines. The locations shown on the original design are not exact. Prior to construction the absorption trench was laid out using Test Hole B as control. The trench falls totally within the 30' radius of Test Hole B. The actual test hole locations were noted during the final as built survey. //5 IZ11271oC 0e�7- 367
