We have therefore moved the location of the septic system to the back of the house as shown on the attached Site Plan. Two additional test holes have been placed with results similar to those achieved on the test holes in the front of the lot. Water monitoring will continue for the next week. The trench, however, will be constructed tomorrow. We have revised the trench design for 10' effective depth and a total length of 50'. The well location has been moved to the northeast corner of the lot to allow placement of the new trenches at the revised location. The impact to Lot 2, Autumn Ridge will be minimized by the movement of the well. The proposed location for the well on Lot 2 is also at the back of the lot and will shadow the protective radius of the well on Lot 3. The revised location of the septic system and well will not impact systems currently in place on surrounding lots or proposed in the future.

We are therefore requesting a permit be issued for the construction of a new well and septic system to serve the new home on the property. 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 well location, alternate site, test hole locations and well and septic systems on the surrounding lots. Drainage arrows are also shown and current drainage patterns will be maintained after construction. The test holes placed near the location of the proposed and alternate absorption trenches indicated tight silty gravel with a percolation rate that varied between 7 and 40 minutes per inch. No ground water was found during placement of the test holes and none was noted during the monitoring period. We are therefore proposing to place a new 1,250 -gallon septic tank with a new 63' long by 3' wide absorption trench with 8' of gravel beneath the distribution pipe. We have averaged the percolation rates and are using an application rate of .6 gallons per day per square foot. The total depth of the trench will be 11' below the surface with the distribution pipe at 3' below the surface. The ground surface on the lot slopes as shown on the site plan from north to south. The absorption trench will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. All components of the new septic system will be constructed a minimum of 100' from any surface water in the area and 10' from water service lines. 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. Lot 3, Autumn Ridge March 25, 2003 Page Two 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, Michael E. Anderson, P.E.

In Accordance With All State and Municipal Guidelines In Effect -On This Date: 1/20/00 A ON-SITE WASTEWATER DISPOSAL SYSTEM CONSTRUCTION AND MATERIAL SPECIFICATIONS SUBJECT: LOT 3, AUTUMN RIDGE SUBDIVISION GENERAL: The scope of this project includes the procurement and placement of a new 1,250 -gallon septic tank at the location shown on the site plan and the construction of a new 63' long by 3' wide by 8' effective depth absorption trench also shown on the Site Plan. The total depth of the trenches will be 11' below existing ground and the distribution pipe will be placed at 3' below the surface. All components of the new absorption trench and septic tank must be constructed a minimum of 100' from the well on the lot and on adjacent lots. A minimum of 4' of cover is required over the septic tank and 3' over the absorption trench. In lieu of cover 2" of direct bury insulation and 2' of cover may be placed. 2. 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. 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 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 A new 1,250 -gallon septic tank must be procured from a certified septic tank manufacturer. 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. Lot 3, Autumn Ridge Subdivision March 25, 2003 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: 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. 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). Lot 3, Autumn Ridge Subdivision March 25, 2003 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.
