Box 196650 Anchorage, Alaska 99519-6650 Ref: Well and Septic Design for Lot 20, Block 2, Tonjess Estates Subdivision To whom it may concern: The proposed 4 bedroom house will be served by a private well and septic system. Several test holes were excavated on the property. The proposed septic system will be designed around the 30 foot radii of test hole #5 and #6. Comments regarding the proposed design are summarized as follows: 1. SOILS: Attached are logs which shows the soil profile, and the percolation test results. The soils below the organic layers are a SM material (primarily shale with loamy, silty soils) to a depth of 17 feet in TFI#5 and to a depth of 18 feet in TH#6 (bottom of test holes). No groundwater was encountered during the excavation of the test holes. A percolation test for TH#6 was performed between the depth of 6.0 feet to 7.0 feet which had a percolation rate of 3.1 minute/inch. It is our opinion that due to the overall appearance of the soils, a application rate of 0.8 gallons/day/ft2 should be used. 2. TRENCH DESIGN: a. Percolation Rate: 3.1 minutes/inch b. Allowable Application Rate: 0.8 gallons/day/ft2 c. Number of Bedrooms: 4 d. Design Flow: 600 gallons per day e. Minimum Absorption Area: 750 fl2 £ Total Depth: 11 feet (max.) g. Effective Depth: 6 feet h. Width: 2.5 feet i. Reduction Factor: N/A i. Minimum Length: 65 feet long j Effective absorption area = 780 ft2 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed upgrade. 4. TOPOGRAPHY: The average topography of this property is a 15 to 20 percent running from approximately southeast to northwest; in short, there are no slope concerns. The trench is to be installed parallel to slope contours. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact me at 337-6179, or 244-9612. Thank you for your assistance.

All materials, components, and construction practices shall comply with the Municipality of Anchorage's latest ordinances regarding wells and septic systems, as well as DHHS policies. The failure of the inspecting engineer to notice a material or construction non-compliance does not relieve the contractor of his/her responsibility to correct such a deficiency. · Septic Tank, Holding Tank, or Lift Station Installation: 1. The burial rating of the tank shall be adequate for the actual burial depth encountered. 2. The tank shall be level and sufficiently bedded to prevent settling or shifting of the tank. 3. All standpipes on the tank shall extend a minimum of 12 inches above f'mal grade. 3 of 4 AWWC, Inc., May 1999 4. Tanks installed with less than 4 feet of cover shall be insulated. 5. The sewer service line from the house to the tank shall be sloped a minimum of 1/4" per foot, unless prior approval is obtained from the engineer. 6. The inlet and outlet lines from the tank shall be bedded in drainrock or the soil shall be adequately compacted to prevent fixture settlement of the soil. 7. A foundation clean-out will be installed, 1-4 feet from the house, if one does not currently exist. 8. Post tank clean-outs shall be installed per MOA requirements. Does not apply to holding tanks or lift stations with pressurized lines. 9. All tanks shall be anchored to resist buoyancy forces in high groundwater areas. This applies when there is not adequate soil cover to resist buoyancy forces. Engineer shall make this determination. 10. The final soil cover shall be graded so that there is positive drainage away from tank. 11. All holding tanks and lift stations shall have an audible and visible alarm inside the residence. 12. All lift stations shall be wired in compliance with all MOA guidelines and the Uniform Electrical Code. 13. The contractor shall remove the old tank, or abandon it in compliance with the Uniform Plumbing Code (UPC). The contractor is solely responsible for the abandonment procedure. · Installation of Conventional Absorption Bed & Trenches: 1. Excavate the proposed bed/trench to the dimensions shown on the design. The bottom of the excavation shall be within 2 inches of level (2 inch maximum variation between high and low spots). If the sidewalls or bottom of the excavation become smeared, they must be raked or scarified before placement of the filter sand or drainrock. 2. The trench or bed should be at least 5 feet from the test hole excavation. 3. All soil tests and excavation depths are advisory to the design and are to be verified in the field by the engineer. If design changes are necessary, and the changes effect the contractor charges to the property owner, the contractor shall obtain approval from the property owner prior to proceeding with the work. 4. Once the drainrock is installed, the distribution pipe is to be placed level (0.02 feet difference between high and low shots) ~vith the perforations faced downward. Drainrock is then to be placed over the distribution pipe, to provide a minimum of 2 inches of cover over the pipe. The draimock shall not be pyramided over the drainpipe but shall be the same elevation over the entire trench/bed width. 5. A silt barrier must be installed between the final drainrock layer and the native soil backfill. The silt barrier shall cover the entire drainrock surface. 6. Monitor tubes shall be installed at the locations shown on the design drawings, and extend a minimum of 12 inches above final grade. The portion of the monitoring tube extending through the draimock shall be perforated from the bottom of the trench/bed to the invert of the distribution pipe. 7. Backfill over the final drainrock layer must not be less than 2 feet. Insulation must be installed when the backfill depth is less than 3 feet. The insulation shall cover the entire width of the trench/bed, the contractor shall "shoot" the final grades to ensure cover depth is adequate, prior to notifying the engineer that the work is complete. The final cover over the drainfield must graded so that there is no potential for water to pond over the trench/drainfield. 4 of 4 MUNICIPALITY OF ANCHORAGE DEPARTMENT OF HEALTH & HUMAN SERVICES Division of Environmental Services On-Site Services Section P.O.
