SUBJECT: Lot 1, Block 1, Northwoods Subdivision Phase 2 Septic System Upgrade Inspection Report We have made the following revisions in accordance with your comments: 1. No maintenance agreement is required. The primary system is a gravity flow trench system. The alternate site is an Advantex Treatment System, but the maintenance agreement is typically required if and when the Advantex system is designed. 2. A cross section is attached showing the surface slope. The slope is 25% or less for 50' from the edge of the absorption trench. 3. The primary and alternate sites are all contained within 30' of the test holes completed during the design phase.

The owner is requesting the new system be designed for a four- bedroom home. We are therefore proposing to replace the tank with a new 1,250 -gallon steel septic tank and 2 new 45' long x 3' wide by 6' effective depth absorption trenches to serve the home on the lot. We are requesting a permit be issued for the construction of a new septic system to serve the home. The attached Site Plan and backup documentation identify the location and configuration of the existing septic system and the location of the new system and alternate site. The area is served by the AWWU water system and no conflicts exist with water services or water mains. The new system will be placed more than 10' from the water service on this lot and those in the area. The existing tank on the lot will be properly disposed on the property and the existing absorption trench will be abandoned in place. The drainage patterns will be maintained after construction. The test holes completed during the initial septic system construction indicated silty gravel from 3' to 14' with a percolation rate of 27 minutes per inch. We have designed the new absorption system for an absorption rate of .6 gallons per day per square foot. A test hole will be placed prior to construction and percolation test completed to verify the soil conditions. The hole will be dug to at least 16' to verify the absence of bedrock in the area. If a slower percolation rate is noted construction will stop and a new design will be completed and submitted to the City for approval. The proposed design includes a 1,250 gallon septic tank and two 45' long by 3' wide by 3' effective depth absorption trenches. A flow splitter valve will be placed to insure even Lot 1, Block 1, Northwoods Phase II July 22, 2009 Page 2 of 2 flow to each trench. A minimum of 4' of fill will be placed over the septic tank and 3' over the absorption trenches. The ground surface on the lot slopes to the southwest at varying grades. The new absorption trenches will be constructed parallel with the existing trench on the lot and as parallel with the contours of the land as possible in conformance with Municipal requirements. If the tank is constructed in accordance with our design the following statements apply: The tank, 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 tank, 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 tank, 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 tank, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

A minimum of 4' of cover is required over the septic tank and 3' of cover over the trenches. 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. 3. 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. The Contractor must also verify the location of wells in the area and assure that the separation distances are met. 4. 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. 5. Contractors installing wastewater disposal systems must be certified by the Municipal Development Services Department Building Safety Division On -Site Water and Wastewater Program for system installations. Owners installing their own systems must receive prior approval from the On -Site Water and Wastewater Program before beginning system installation. SEPTIC TANK INSTALLATION A new 1,250 -gallon septic tank must be procured from an approved source and installed at the location shown. 2. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. Lot 1, Block 1, Northwoods Phase II July 22, 2009 Page 2 of 3 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. 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 the distribution line must be perforated. 5. Contractor shall verify the septic tank and drainfield are a minimum 1 00'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. All pockets of unacceptable materials must be removed and replaced. Lot 1, Block 1, Northwoods Phase If July 22, 2009 Page 3 of 3 MATERIAL SPECIFICATIONS: 1. 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 or owner shall provide a copy of all field survey layout and construction notes for use in preparing the certified as -built of the completed system.
