Robert Bell and Associates (FRBA) was retained by BTH Construction, LLC to provide third party inspection services on the above referenced septic system construction. Two inspections were performed by FRBA. The first inspection took place at 4 pm on Friday, August 29, 2003. All of the excavations were completed and the septic tank was in place, but not backfilled. The second inspection took place at 11 am on Saturday, August 30, 2003. All of the system piping, filter sand and washed rock were in place and the system was ready for backfill. Upon both inspections, we found the construction to be in compliance with the plans and specifications as approved by the MOA for this project. Workmanship and quality of construction were more than adequate. If you have any questions regarding our inspection services, or this correspondence, please feel free to contact me at 274-5257.

Box 196650 Anchorage, AK 99519-6650 RE: Proposed Well and Septic Design Lot 2, Hillside North, Addition No. 9 To Whom It May Concern: The proposed 3 bedroom house will be served by a private well and an on-site septic system. One test hole was excavated on the subject property during the development phase of this subdivision. A copy of this test hole log has been attached for your review. Both the primary and the replacement drainfields have been designed around the 30 foot radius of this test hole. Various test pits have recently been excavated around the lot which confirm the observations recorded on the attached test hole log. Additionally, the soils will be visually classified during construction to ensure that they are consistent with the attached test hole log. We are proposing the installation of a 1,000 gallon septic tank and 5 foot wide x 50 foot long drainfield to meet the wastewater disposal requirements of the proposed structure. Comments regarding this design are summarized as follows: Soils See attached soils log which details soil classifications, groundwater observations and percolation rates. Drainfield Design See attached design drawings for drainfield sizing calculations. Surface Waters There is a small stream to the north of the proposed drainfield. The primary and replacement drainfields were carefully placed to ensure they are more than 100 feet from this stream. Topography The lot has a gentle slopes from south to north and the proposed drainfield area is predominantly level. The proposed construction will not alter or impede the lot's natural drainage. Groundwater and Bedrock No groundwater or bedrock were observed at any time during the original test hole excavation or in any subsequent test pits excavated on the lot. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions or comments on this design, please feel free to contact me at 230-3992.

Post tank clean -outs shall be installed per MOA requirements. Does not apply to pressurized lines. 11. In areas with high groundwater, the septic tank shall be sufficiently anchored to resist buoyant forces when there is not adequate soil cover to resist the uplift force. The contractor shall refer to the engineer for direction regarding this matter. 12. The tank backfill shall be graded sufficiently to ensure positive drainage away from the tank. 13. All holding tanks and lift stations shall have an audible and visible alarm inside the residence being served. 14. All lift stations shall be wired in compliance with all MOA guidelines and the Uniform Electrical Code. A municipal electrical permit and inspections must be obtained in areas where required by the MOA. 15. The contractor shall verify that the septic tank/lift station is a minimum of 100' from any residential water well, 150' from any class 'C' well and 200' from any community water wells. Additional separation distances must also be maintained. Drainfeld Construction: 1. The drainfield shall be constructed per the dimensions outlined in the design drawings. If any discrepancies are noted, contact the Engineer immediately for clarification. 2. The bottom of all trenches shall be within 2° of level. If the sidewalls or bottom of the excavation become smeared, they must be raked or scarified prior to placement of drainfield filter sand or septic rock. 3. A minimum of 2 feet of accepting soils is required below the drainfield rock for a 5' wide trench. The contractor shall verify this condition prior to placement of the septic rock. All pockets of unacceptable materials shall be removed and replaced. 4. The trench or bed must be a minimum of 5 feet from the test hole excavation. Lot 2, Hillside North #9 Notes and specifications Page 3 of 4 5. All distribution piping must be installed level with the perforations facing downward, atop a level bed of drainfield rock. Septic rock shall then be placed atop the distribution piping to provide a minimum of 2 inches of cover above the piping. The septic rock shall not be "pyramided" over the top of the pipe, but shall be installed level across the entire width and length of the trench or bed. 6. A silt barrier or geotextile fabric must be placed between the drainfield rock and the native backfill. Installation of rigid board foam DOES NOT eliminate the need for the silt barrier. The silt barrier shall cover the entire drainrock surface. 7. Monitor tubes must be 4" in diameter and installed in the locations depicted on the design drawings. The portion of the monitoring tube below the septic rock must be perforated and the portion above the septic rock shall be solid. The monitoring tube shall extend a minimum of 12" above finished grade. 8. Backfill over the final gravel layer must not be less than 2 feet. Insulation must be installed when the backfill depth is less than 3 feet. 9. Drainfield trench backfill shall be mounded to prevent depressions from forming due to subsequent settlement of the backfill material. Grade areas adjacent to the drainfield to direct surface runoff away from the absorption trench. 10. The contractor shall verify that the drainfield is a minimum of 100' from any residential water well, 150' from any class 'C' well and 200' from any community water wells. Additional separation distances must also be maintained. Material Specifications: The contractor shall ensure that ALL materials being used are in compliance with the most current guidelines established by the Municipality of Anchorage. Please refer to "Standards and Specifications for Component Parts and Materials Used in Construction of On -Site Wastewater Disposal Systems", dated December 2000, as provided by MOA DSD, On -Site Water and Wastewater Program. This document details the basic standards and specifications for the following septic system components: Septic tanks. Lift Stations. Holding Tanks. Pipe Materials. Insulation. Inspections: 1. A minimum of two inspections are required by the Municipality of Anchorage. These inspections must be conducted under the supervision of a Professional Engineer licensed to practice in the State of Alaska. The first inspection must take place upon completion of the excavation for trenches, beds or pits and before the installation of any filter sand or drainrock. A septic tank may be set in place, but may not be backfilled. A tank may be set in place, but cannot be backfilled. The second inspection must be conducted after the placement of the filter sand, drainrock, monitoring tubes, standpipes, cleanouts, filter fabric and insulation. No backfill should be in place at the time of inspection. Lot 2, Hillside North #9 Notes and Specifications Page 4 of 4 2. The contractor shall provide a legible copy of all field notes relating to system layout and construction to the Engineer for use in preparing the record drawings for the proposed septic system. 3. The contractor shall coordinate all inspections with the Engineer. A minimum of 24 hours notice is required prior to start of construction. If necessary, a pre -construction meeting will be held on-site. woot •A�,a 4918 BRIAN T. HARTEN CE -10068 dept R ► pfi��o3.,,.•4�� , ..
