The installation will serve an existing four (4) bedroom house. This lot and surrounding lots are served by a public water system. Currently there are no wells within 100ft of the proposed installation. The initial system for the subject lot is approximately 28 years old. The tank is nearing the end of its expected lifecycle, and the field is in failure. 1. Soils: Test holes were performed on this lot in August of 1998 by Michael E. Anderson for the design of the initial system. Approximate locations are shown on the attached site plan. The existing soils logs are included in the subject parcel’s onsite records. Groundwater was not observed during the excavation of the existing test holes to a depth of 20.0’ BGS, and bedrock was not encountered. The proposed replacement field is located in the replacement location indicated and approved as a part of the initial system installation. Based on the documented results of the percolation test, overall soils appearance and initial design application rate, an application rate of 0.6 gpd/SF was used for the design of a conventional wastewater treatment system located in the position indicated as “Alternate Site” on the initial plan set. 2. Soil Absorption System Design: See design package. 3. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field. 4. Topography: See attached site plan 5. Drawing Markings: The Drawings are marked “For MOA Review Only”. When written notification that the review is complete and no further comments are received from MoA On-Site Department, the note will be removed and “For Construction” drawings will be issued. The proposed installation will not affect the future development of this or the surrounding lots. If you have any questions, please contact me at (907) 745-8200. Sincerely, Steven R. Pannone, P.E. F.

(owner/designee) ISSUED BY: DATE: DATE: db/ll5 October 29, 1998 Municipality of Anchorage Department of Heath & Human Services 825 "L" Street Anchorage, AK 99502-0650 Subject: Lot 11, Block 1, Sky Hills Subdivision Septic System Design Impacts to Adjacent Properties Dear Onsite Services Engineer: The owner of Lot 11, Block 1, Sky Hills Subdivision intends to construct a four bedroom home on the lot. We are therefore requesting a permit to construct aseptic 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 show the location of the new system. The testholes placed on the property revealed sands ranging from well to poorly graded. Some silt pockets were found in the sand. Percolation rates ranged from 6 to 20 minutes per inch. The system is designed for the slower rate. Groundwater was not encountered during the excavation nor was any noted during the monitoring period. We have therefore designed a 3' wide deep absorption trench with 8' of gravel beneath the distribution piping. The trench will be 63' long with a total depth from original grade of 13'. The ground surface of the lot slopes to the northeast at rates between 2% and 10%. The absorption trench will be placed across the slope near the northeast corner of the lot to provide sufficient fall from the house for gravity flow. No other lots surrounding this lot are currently being developed. No conflicts currently exist with other systems in the area. Lot 11, Block 1, Sky Hills October 29, 1998 Page Two If the 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 subdivision is served by the Municipal water system. 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.

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: 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.

All drain rock shall be .5" to 2.5" in diameter with less than 3% passing the #200 sieve. INSPECTIONS: 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.
