Box 102954Anchorage, Alaska, 99510 (907) 272-821818 (907) 272-8211 Fax August 23, 2006 Mr. Mike Weiman Seven Peaks Investment 605 W. Tudor Road Anchorage, AK 99503 Dear Mr. Weiman: Subject: Lot 93A, Monroe S/D Site Investigation You contacted me to perform soils test holes to assist you in the subdivision of the above referenced property and to determine the suitability to install on-site wastewater disposal systems on the subdivided lots. Currently lot 93A is a single lot. There is an existing two- bedroom house on the property located in the southeast corner of the lot. This house has an existing undocumented septic tank and drain field located to the northwest of the building. The house has an undocumented well located within the structure. There is an AWWU 18" diameter sewer truck line at the southeast corner of the property. Topographic Information A topographic survey was not performed as part of this investigation. We did walk the entire site within the property boundary. The lot has to distinct areas. The eastern half of the lot is a plateau, while the western portion is lower at street level. The eastern portion slopes to the west at approximately 5%. The eastern property line is a bit steeper and slopes at 15 to 20 percent. The transition from the plateau to the lower section is through a 25 to 30 percent slope. Portions of this slope are comprised of fill and debris. The lower portion of the lot slopes to the northwest at approximately three to five percent. The grades are fairly consistent throughout the lot. See the attached site plan. Documentation of Water Availability to Serve Water Wells The subdivision is surrounded by documented and undocumented water wells. The well that currently serves Lot 93A was tested. The static water was measured at seven feet below the top of the casing with a total depth probed to 150 feet below the top of the casing. A recovery test was performed and the well recovered at a rate of 0.5 gallons per minute (GPM). An in-depth record research was performed of the MOA records. A summary of the surrounding wells as well as a copy of the well logs is attached to this letter. The results indicate that the average production of the wells for this area range from 0.4 GPM to 5 GPM. One well has an estimated flow of 55 to 75 GPM and is considered an anomaly in the analysis. Well production appears to improve as one moves north of the existing well serving this lot. Realistically, the well production on the Page 2 of 3 northern portion on Lot 93A would be expected to be in the 0.5 to 1.5 GPM range. This production meets the minimum requirements for the development of a four bedroom house within the Municipality. Site Investigation and Documented area for Septic Systems The site investigation was conducted on March 17, 2006. Five test holes were excavated on the lot on that date. The attached soil logs shows that we encountered a variety of soils in the test pits. The lower portion of the lot is covered with one to two feet of organic material (peat and root mass) with poorly graded gravels to silty gravels underneath. Three of the test holes had a layer of brown silt ranging from one to three feet thick under the organic layer and above the gravely layer. The test hole on the upper portion of the lot showed the organic layer had been removed and replaced with a one -foot layer of topsoil. The soil under the topsoil was sitly gravel, with clean fractured gravel underneath. We encountered bedrock in all five holes at a depth varying from 9 to 11.5 feet below the surface. Ground water was encountered in the four test holes on the lower portion of the lot. Ground water was not encountered in test hole five on the upper portion of the lot. The ground water was monitored through the seasonal high water period on the 14th of May. The ground water was measured at a depth of four to six feet below the surface on the lower portion of the lot at the seasonal high water level. Test hole five had water levels eleven feet below ground level on May 14, 2006. The percolation rates were measured between 1.5 MPI and 11.5 MPI, with an average rate of approximately 8 to 10 MPI. According to AMC 15.65.180, the required area for a subdivision with this measured percolation rate needs to have a reserve area of 12,000 square feet per lot. The attached site plan shows the approximate location of the test holes, proposed lot lines, known features that would affect the placement of a soil absorption system. The Municipality of Anchorage Regulations govern for single-family homes, and require a minimum of four (4) feet vertical separation between the bottom of a soil absorption system and ground water for a conventional system, have at least two feet of unsaturated native soil, six feet (6) to bedrock or other impermeable layers (tight silts and clays), must be located greater than 100 feet horizontally from any surface water (Creeks and ponds) and located over 50 feet up -gradient from a sub -drain system. Additionally, the accepting soils must have a percolation rate of less than 120 minutes per inch. A lot must have room for a primary and reserve soil absorption system. There is an existing undocumented septic system located on the southern portion of this lot. The system was exposed and documented. The house was built sometime in 1959. The construction material used in the system appears to be from the early to mid 60's. The exact date of installation is unknown — it is assumed that the septic system was C:\Work\Letters\93A Monroe_Soils_002.doc Page 3 of 3 installed at the same time as the house. During the investigation process, some minor damage was noted (collapse pipes, broken sump pipes and no filter fabric.) These issues were corrected before backfilling of the system, including installing a second clean-out on the tank. The septic tank is located 85.8 feet from the existing well, and the septic drain field is located 96.9 feet from the well. This system appears to have been constructed under the regulations in effect at the time of construction and met the separation distances required at that time. Conclusion In conclusion, the site investigation shows that conventional soil absorption systems can be installed on the subject lot based on the soils discovered, the percolation test performed, and the ground water monitoring conducted to date. The soils encountered are average percolating soils (8 to 10 min/inch). I would recommend using a shallow trench system. The attached site plan shows the 12,000 sf available area for on-site wastewater disposal systems as required by the MOA code.

Date 10/24/06 Engineers Comments: In conducting an adequacy test, l attempt to provide a thorough, conscientious engineering analysis of the system in accordance with MOA DSD Guidelines & Regulations. Ile reported results describe the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil condition, ground water levels that may fluctuate during the year, and the water usage of the family being served by the system. 71ese conditions are outside the control of the evaluator of this system. All systems eventuall fail and satisfactory test results do not guarantee future perfomtance of the system, nor do they guarantee that there are no encroachments. PFS can therefore not provide any warranty for future performance nor give any estimate of ,t v continue to meet the operational requirements of the MOA DSD. 7be content of this reportis for the sole to owner Any reliance upon or use of this report by any other person or party is not authorized nor will it confer an ght what 5.

The minimum well productivity required by this Department (AMC 15.55) for a 2 -bedroom residence is 0.21 gallons per minute. Although the subject well currently exceeds this minimum requirement, all parties concerned are advised that the production capacity of the well may fluctuate. Restriction of non-critical water uses such as washing cars and watering lawns and gardens may be required. This advisory must be attached to all copies of the subject Health Authority Approval.
