Box 102954 (907) 272-8218 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 Anchorage, Alaska, 99510 (907) 272-8211 Fax 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 (61 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.

Box 196650 Anchorage, Alaska 99519 Subject: S-11513-1 Monroe Subdivision Response to Comments Mr. Roth: ;e, Alaska, 99510 272-8211 Fax You contacted Mr. Steven Pannone of Pannone Engineering Services, LLC concerning the above project on September 28, 2006. During that telephone conversation you indicated that there were still a few outstanding issues that needed to be addressed concerning this subdivision. This letter will address those issues you conveyed to Mr. Pannone. Comment: Ground water in Test Holes 1 and 2 where within four feet of the surface. Need to perform a percolation test on the MI/Gm layer at a depth of one to three feet below ground surface. Response: Additional Percolation tests where performed on test holes 1 & 2 at the depth of two to three feet below ground level. The percolation results are presented in the revised soil log and percolation test sheets attached. Comment: The pipe material used on the clean-out pipes is the wrong material. The clean -outs need to be schedule 40 PVC. Response: According to the Municipality of Anchorage Standard Specifications for Component Parts and Material Used in Construction of On-site Wastewater Disposal Systems, Dated January 1991, Section 5, Approved Pipe Material ASTM D3034 PVC pipe is approved for use as clean-out or standpipes. Comment: Documentation of existing septic system. Would like to see the photos of the investigation and repair. Response: Photos of the investigation and repair are attached. Comment: Drainage on northern portion of Lot 93A-1 appears to be creek and is too near the septic system. Res oonnse: Drainage is from the Municipality of Anchorage Right -of -Way (MOA ROW) north of Lot 93A. We have had discussions with Mr. Jack Puff and Mr. Will Pace of the MOA ROW Department and Page 2 of 2 they agree that the water is coming from their right-of-way and that it is their problem. We are in the process of developing a fix that will prevent the water from impacting lots 93A-1 and 93A-2. Mr. Puff is in the process of determining if MOA Street Maintenance has the time and money to perform the repair. Additionally, the water from the right-of-way varies depending on the amount of rainfall. The point where the water enters lot 93A-lhas recently been a slow trickle to no water and the water level in the drainage path on lot 93A-1 has been contained in the drainage pipe below the level of the gravel. Water levels do rise above the level of the gravel during storm events, but return to normal levels below the gravel within 48 hours after the storm even. Anchorage and Eagle River has seen an unusual year for storm events this year. We have had continuous rain fall through the months of August and September, for a total rainfall during those months as twice the monthly averages. Once the rain stopped, the water levels in the drainage returned to normal levels below the gravel level. Comment: The northern lot does not have the required 12,000 sf area for a septic reserve as required by the subdivision regulations, since test holes 3 and 4 have water to within two feet of the surface. Response: Test hole 5 is located on the eastern portion of lot 93A-2. There is over 12,000 sf available on the eastern portion. The existing man-made step slopes will need to be flattened to a maximum slope of 25%. We have revised the site lay -out plan to reflect this. 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. 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.

Box 196650 Anchorage, Alaska 99519-6650 Subject: HAA for Private Well & Septic System. Lot 7A, Bk I -A, Lake Ridge Terrace SID. 14742 East Lake Ridge Drive. Waterfront on Fire Lake. To whom it may concern: The subject lot has a 3 bedroom house on it which is served by a private well and septic system. The results of the field investigation and adequacy tests are summarized as follows: A: WELL UNDOCUMENTED: When the septic system was installed in 1969, it was noted on the inspection report that the water source was Fire Lake. In short, there was no well at that time. Upon my initial inspection, two wells were identified on the lot, one near the northeast lot comer, and one near the southeast lot corner. The well at the southeast comer was not in use, uncapped, and according to the property owner (Mr. Waner), `Stever really produced any water". In addition, it was only about 86 feet from the septic tank. This well (southeast comer of lot) was decommissioned by cutting it off 2 feet below grade, filling it with concrete, and welding a steel cap on the top. The well at the northeast comer of the lot is active. B. WELL CONSTRUCTION: The well was inspected by Dave harper, Alpine Drilling, on, or about, 7/5/97. Ile left a telephonic message for me on the morning of 7/7/97 indicating that the well was cased to a depth of 38.5 feet, with perforations starting at 37 feet. Ile asked if I would prepare the report, based upon his message, since he would not be able to write a report at this time due to extenuating circumstances (death of son the previous day). Attached is an as -built survey, dated 7/8/73 which shows the subject well, confirming that it was constructed prior to 1975. It is my understanding, in talking with Dan Roth (DHHS engineer), that wells drilled prior to 1975 were under State regulation, which only required a casing depth of 30 feet. If this is correct,. the subject well should be "grandfathered" in under the old regulations. Please provide direction from your department. C. WELL ADEQUACY TEST: The static water level on 6/16/97 was 35' BTC (Below the top of the casing). Water was pumped from the well at a rate of4.2 Spm for a 25 minutes (105 gallons). This caused the water level to drop 53 feet, down to the pump level (set at 88 feet). In short, the well was "dry". The pump was then turned off at the breaker. The recovery was monitored for 60 minutes. The results are summarized as follows: RECOVERY: Time (minutes) Water Level in Well - 0 ]1•0 88 feet 5 85 10 83 20 79 30 76 45 70 60 65 7.5 13.5 18 27 34.5 The recovery in one hour was approximately 34.5 gallons, or .58 gallons/minute. The pump was turned on again, until the water level was drawn down to the pump intake. This took approximately 13 minutes, and total flow of 37.7 gallons. The recovery of the well was then monitored over a period of 120 minutes. The results are summarized as follows: RECOVERY: 'rime (minutes) Water Lievel RTC* mal Gallons Recovered Casino 0 89 feet 0 3 87 4.5 16 83 9 30 . 78 16.5 46 73 24 60 69 30 75 64 37.5 90 59 45 120 49 60 The total volume recovered in the casing is approximate, and based on an assumption of 1.5 gallons/fl. Based upon the data, over a period of 218 minutes (38 minutes,pumping, and 180 minutes monitoring recovery) it can be seen that the recovery of the well is approximately 0.5 gallons per minute. The ability of the well toproduce at this ratejor an extended_period,of time, or seasonally (well production is typically lower in late winter) is uncertain. Based upon this data it was determined that the capacity of the well meets the Municipal requirement for a 3 bedroom house (.31 gallons per minute), however, a storage system will be necessary in order to meet peak demands D. SEPARATION DISTANCE FROM WELL TO SEEPAGE PIT: Attached is a drawing prepared by Alaska Water & Wastewater, which indicates that the existing seepage pit is approximately 98.5 feet from the well. Also attached is a survey by Robert Johnson, L.S which states that the separation distance from the crib to the well is exactly 100 feet. Given the accuracy of the instrumentation used by the surveyor, it is reasonable to assume that his assessment is the more accurate of the two. In reality, it is not possible to determine the actual separation distance without exposing the gravel perimeter of the seepage pit (which 'would require removing the concrete floor). E. SEPTIC SYSTEM: The septic system was installed October of 1969 and consists of a 1350 gallon concrete septic tank, and a cement ring seepage pit. Some time later, the garage was constructed over the seepage pit area. In June of 1997 the homeowner had Denali Pumping locate the seepage pit using a transmitter. Once located a hole was cut in the concrete floor, and the top of the concrete lid exposed. A 4 inch diameter hole was core drilled into the lid, and a 3 inch diameter clean-outlinspection pipe installed. The north sidewall of the septic tank was used as part of the foundation for the addition (garage). The top of the concrete tank is flush with the ground surface, and is uninsulated. It is my understanding that the system has functioned adequately this way, since 1969. Prior to starting the adequacy test (6/16/97) the seepage pit (S.P.) had 9.625 inches of liquid in it. The septic tank had been pumped on 6/10/97 so the system had an opportunity to recover somewhat. Water was added into the S.P. at a rate of 5.04 gpm for a total of 126 minutes (635 gallons). The liquid level rose 30.875 inches, for a total depth of 41.5 inches. The recovery was monitored for 30 minutes, during which time the level remained virtually unchanged. Based upon this data, it was determined that the system would need to be filled to a greater depth in order to achieve any significant absorption. An additional 596 gallons was introduced over a period of 120 minutes. The liquid level rose from 41.5 inches to 64.625 inches (rise of 23.125 inches), which corresponds to 25.8 gallons per inch. The recovery was monitored for 60 minutes, during which time the level dropped 3.75 inches, indicating an absorption of 96.8 gallons. Based upon this data the absorption rate was deemed to be adequate for. a 3 bedroom house (450 gallons per day required). The septic tank vent (see attached photograph) and lids are caulked with mastic so there can be no intrusion of surface water. Per Mr. Waner, the vent was installed to prevent sewer gases from venting into the garage area. Every time the lids are removed (for tank pumpinglcleaning) the vent and lids will have to be recaulked by the homeowner. F. SEPARATION DISTANCE FROM SEPTIC TANK TO WELL ON LOT 8, BK I -A: I was able to locate two wells on the lot immediately to the south, Lot 8, Bk 1-A. One of the wells is about 99 feet from the septic tank on Lot 7A. Lot 8 has a commercial type structure on it that is being used for a mechanics shop. The lot is not served by public sewer, and does = have a septic system. I was able to see a porta-potty in the garage. In short, the well is not used to any significant extent. When the septic tank was installed (10/69) on Lot 7A, the required separation distance to a private well was 50 feet, and to a class " C' well was 80 feet.
