We are therefore requesting a permit be issued for the construction of a new well and septic system to serve the new home. No conflicts exist with adjacent septic systems or wells and the proposed septic system and well on this lot. The attached Site Plan and backup documentation identify the location and configuration of the proposed well, septic system and alternate site. The current drainage pattern is identified on the Site Plan. The drainage pattern will be maintained after development of this lot is complete. Test holes were recently placed on the lot, which indicated well graded to poorly graded silty sand with some gravel in the area of the absorption trench and alternate site. The accepting soils were tested and found to have a percolation rate of less than 1 to 4 minutes per inch in the accepting soils. No groundwater was encountered in either test hole and none was noted during the ensuing monitoring period. Our design includes the placement of a new 1,250 -gallon septic tank along with a 50' long by 5' wide by 4' effective depth absorption trench to collect and treat the sewage generated in the house. The bottom of the trench will be 7' below the surface. The distribution pipe will be 3' below the surface. A minimum of 3' of cover will be placed atop the trench and a minimum of 4' of cover will be placed atop the new septic tank. The ground surface on the lot slopes at varying grades from east to west as shown on the Site Plan. The absorption trench will be constructed parallel with the slope of the ground surface as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from the well on the adjacent Lot 15, Block 1, Williamson August 31, 2005 Page Two lot. It will also be constructed a minimum of 100' from any surface water in the area. 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. 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.

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. Work also includes the construction of a new 50' long X 5' wide X 4' effective depth absorption trench at the location also shown on the Site Plan. The distribution line in the trench will be placed at 3' below the existing ground surface. Total depth of the trench will be 7' below the existing ground surface. A separation distance of 100' from any well and 100' between the septic tank and absorption trench and any surface water must also be maintained. In addition, a separation distance of 10' between components of the septic system and any water service line is required. A minimum of 3' of fill is required over the absorption trench and 4' over the septic tank. In lieu of the required fill 2" of insulation and 2' of fill 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. 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 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 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 15, Block 1, Williamson August 31, 2005 Page 2 of 3 3.

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 15, Block 1, Williamson August 31, 2005 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.

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.

The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & 4/21/23 Municipality of Anchorage -• Development Services Department Building Safety Division OnSdeWater and Wastewater Program ,, •; ' 4700 Elmore Road P.O.
