June 14. 1999 Municipality of Anchorage Department of Heath & Human Services 825 "L" Street Anchorage, AK 99502-0650 Subject: Lot 7, Block 3, Sky Hills Subdivision Septic System Design Impacts to Adjacent Pr'operties Dear Onsite Services Engineer: The owners of Lot 7, Block 3, Sky Hills Subdivision intend to construct a four bedroom home on the lot at the location shown on the attached Site Plan. We are therefore requesting a permit to construct a septic system on the lot to serve the house. The subdivision is served by the Municipal water system so a well permit is unnecessary. The attached site plan and backup documentation describe the proposed system and the location of the new system. The testholes placed on the lot revealed poorly graded sands with some silt. Percolation rates ranged from 8 to 12 minutes per inch. No groundwater was encountered during excavation and none was noted during the monitoring period. We have therefore designed a deep absorption trench with 8' of gravel beneath the distribution pipe. ']-he trench will be 50' long, 3' wide and have a total depth of 11.5' from the original ground surface. The ground surface of the lot slopes from west to east at rates from 8% to 10%. The absorption trench will be constructed across the slope toward the northeast corner of the lot to provide sufficient fall from the house for gravity flow. All lots in the subdivision are served by the water system and no conflicts exist between any septic systems currently under construction or planned for the future. Lot 7, Block 3, Sky Hills Subdivision June 14, 1999 Page Two If the 1. system is constructed as designed 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. 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. The system, if constructed as designed, will have no adverse impact on reserved space, either surface or subsurface, on any lots located in the area. 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. It also includes the construction of a new ,50' long x 3' wide x 8' effective depth absorption trench at the location shown on the attached Site Plan. Distribution piping will be placed at 3' below the surface. The total depth of the trench will be 11.5' below existing ground. 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. 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. 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. Contractors nstalling wastewater disposal systems must be certified by the Municipal Department of Health and Human Serwces for system installations. Owners installing their own systems rnust receive prior approval from [:).H.H.S. before beginning system installation. SEPTIC 1.

The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 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. 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. 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. A silt barrier or geotextile fabric must be placed between the drainfield rock and the natural soil backfill. 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. Lot 7, Block 3, Sky Hills Subdivision June 14, 1999 Page 3 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 trenches 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: Septic tanks must be constructed by a Municipally approved septic tank manufacturer. 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.

Lot 7, Block 3, Sky Hills Subdivision June 14, 1999 Page 4 INSPFCTIONS: A minimum of two inspections are required by Municipal Ordinance. 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. • EfC).1" Municipality of Anchorage Q* On-Site Water and Wastewater Program a G£; IMaF (907) 343-7904 eo° S A A E T Y CERTIFICATE OF ON-SITE SYSTEMS APPROVAL Parcel I.D. 011-122-29 Expiration Date: 9- i q_/ 7 1.

Engineer's Comments: This investigation was completed in compliance with ADEC and MOA regulations. 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 inland use, local soil characteristics, groundwater levels that may fluctuate during the year and the water usage of the family being served by the system. 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, ArcTerra can not give any estimate of how long a system will function satisfactory for current or future occupants or can ArcTerra guarantee that no unseenASP- �+�\ encroachments,deficiencies or discrepancies exist.
