October 24, 1991 PH: (907) 345.1355 John Smith M.O.A. DHHS P.O. Box 19-6650 Anchorage, AK 99519 Dear Mr. Smith: This submittal provides the information requested on Ms. Oswalt's 2nd pink transmittal sheet dated 10/16/91 regarding our application for a sewer permit to serve a proposed residence on Lot 15, Block 2, Spring Forest S/D. The reason we anticipate sewage will not come out the side of the 38% slope on the downhill side of the bed is that the bed is to be constructed 7.5 feet below ground level, and the majority of the overlying soils are a relatively impermeable sandy silt. Even assuming the unlikely worst case that the sewage were to attempt to migrate horizontally through the silt from the bed instead of vertically down into the sand, it would have to pass through 20 feet of undisturbed native soil before daylighting. This is considerably more horizontal protection than is afforded by a conventional mound system with 2 feet of imported soil cover and 33% side slopes. As stipulated by your office we conducted a 9th soil test (log enclosed) in the south portion of the lot. As previously predicted in my letter dated 10/2/91 the soils encountered are predominantly a sandy silt. The density increases with depth and we were unable to dig deeper than 13 feet due to the presence of a large rock. We conducted a percolation test between 4.75' and 5.25' in the zone which visually appeared to be most permeable. Even during the presoak phase, when there were 11" of head in the pert test hole, the measured percolation rate was slower than 60 minutes per inch. Based on this test I am still of the opinion that the south portion of the lot does not offer a suitable location for construction of an on site soil absorption system. On the other hand, it i9 my opinion that the excellent soils encountered in the location of the proposed design will result in a good soil absorption system, despite somewhat higher construction costs.

Because the proposed bed will be constructed in quite permeable sand at a chance thatgeffluent wiificant ll ever th daylight out)which the siderof thenain natural slope on the impermeable side of the rbed little The water service line is not in yet, and we were not able to find the exact location of the Mueller valve, however the water main is located in West Tree Drive, so there will be no conflict between the water service line and the proposed soil absorption system. Based on the quite extensive soils testing program which we conducted on this lot, it is my opinion that the proposed site is the most viable location on the lot for construction of on-site soil absorption system. Research on soils tests conducted on adjacent lots, coupled with the trends established by our 8 test holes on this lot, have convinced me that the subsurface soils on the south end of the lot consist basically of a tight silt which is generally unsuitable for construction of a soil absorption system. The December 1982 soils test conducted by Melvin Nichols for Joe Cange, referenced as being on Lots 14 & 15, classifies the soils as being a wet, stiff, sandy gravelly silt. Mr. Nichols was able to get a marginally acceptable perc rate of 37 minutes per inch in a slightly more gravelly zone between 5 and 7 feet, however bear in mind that this test was done in December when soil conditions are generally quite dry. I would expect any system constructed in this material to fill up with groundwater during breakup. Lee Reid's soils test on Lot 15, Block 1, across the street from the subject property, also showed there to be pure silt below 2'. 1 would expect the deeper material would perc at a slower rate than the marginal 50 min/n. which he reported at 2.5 feet. Our test holes fit in with this continuum, showing sand at depth near the top of the slope, with pure silt further to the south. Based on this analysis, it is my opinion that the soils near the south end of the lot are not suitable for construction of a soil absorption system, and I think it would be a mistake to try to install a system in marginal soils, when we have much better materials at the proposed site. Please give me a call at 345-1355 if you want to discuss this further. Sincerely, Ted Moore, P.E. cc: Jeff Keim CIVR.6 ENMONS ENTAL ENGLNEERLNG • ENERGY CONSERVATION 6 A.NALYSis 14530 ECHO ST.

Box 19-6650 Anchorage, AK 99519 Dear Sirs: The purpose of this letter is to provide the required design narrative in support of our application for a permit to construct wastewater disposal facilities on Lot 15, Block 2, Spring Forest S/D, located at 6151 West Tree Drive. Soils logs, perc test results, a site plan, design drawings and specifications are enclosed e for your review. The proposed system will be constructed in the vicinity of test holes #1 and #6. As can be seen from the soil log for test hole # 1, the native material below 7.5 feet is a slightly silty sand with a measured pert rate of 2.2 minutes per inch. Using the soil application rate of 0.8 gpd/sq. ft. specified in the wastewater ordinance for a bed type soil absorption system constructed in this material, a 4 bedroom residence requires a total absorption area of (4 x 150)/0.8 = 750 square feet. The proposed 15' x 50' bed design has a total absorption area of 750 square feet. A similarly sized site for a replacement system is shown between test holes #6 & #8. In evaluating the soils information for this reserve site it should be recognized that the natural ground elevation at test hole #8 is approximately 6' higher than at test hole #6, thus the proposed receiving stratum is at a comparable elevation. As indicated on the site plan, the topography in the proposed construction area slopes to the northeast at an average of 27%. Just northeast of the proposed site and of the reserve area the slope steepens to approximately 38%. Despite these relatively steep slopes, daylighting of effluent from the soil absorption system should not be a problem because the proposed bed is quite deep, and the overlying ML material will present a barrier to horizontal migration of effluent further downslope. It should also be noted that the subdivision plat designates a 20' wide drainage easement along the eastern boundary of the lot. There is a culvert running under West Tree Drive providing storm drainage from land located to the southeast. On the date of our initial soils tests on August 2 (immediately after a heavy downpour) there was a trickle of water running through the culvert, although no surface water was visible in the ditch upstream. We subsequently monitored the culvert and drainage easement on August 9, 10,12,14, 28 and September 4 and 11. There was no water running through the culvert or in the drainage swale below on any of these occasions, except that on September 11, after a rainy week, water was dripping from the outlet of the culvert. Based on these observations, as I have already discussed with John Smith, one can conclude that this drainage easement does not constitute a surface water source requiring a 100 foot separation from on-site wastewater disposal facilities. There is a continuously flowing stream crossing the northeast comer of the lot as shown on the site plan. Unfortunately, the designated 100 foot offset from this stream does not leave enough room for construction of a soil absorption system at the toe of the slope in the vicinity of test holes #5 and #7, however the proposed original and replacement sites are both outside the required 100' setback from that stream. f ` �r ``QQ` TT P �TErGHNICAL SERVICES CIVR.6 ENMONS ENTAL ENGLNEERLNG • ENERGY CONSERVATION 6 A.NALYSis 14530 ECHO ST.

Minor deviations from these drawings may be allowed or required by the engineer conducting the inspections. All construction procedures and material specifications shall conform with Municipal and State requirements. 1.3 All separation distances shall be in conformance with Municipal requirements, unless specifically waived. 1.4 The contractor shall be responsible to obtain any necessary utility locates, and to work around any buried utilities. 1.5 Please note that the proposed soil absorption bed site is on a significant slope which will affect both the ability to maneuver equipment and to stockpile the significant amount of material which will have to be excavated. The contractor shall take particular care to minimize damage to surrounding trees, and after the system is installed to restore the site to as near to original conditions as possible. 2.0 Septic Tank: 2.1 The 1250 septic tank shall be Municipally approved with a minimum of two compartments, and shall be set level on undisturbed soil. Each compartment shall be equipped with a watertight manhole cover and a 4" cleanout. If the tank is buried less than 4 feet, it shall be insulated with 2 inches of approved burial type, rigid insulation. 2.3 All pipe connections to the tank shall be equipped with waterproof mechanical couplings. The waste line from the residence to the septic tank shall have a minimum slope of 1/4"' per foot, and the waste line between the tank and the soil absorption system shall have a minimum slope of 1B" per foot. A cleanout shall be installed within 5 feet of the building foundation, and a double cleanout shall be installed within 5 feet downstream of the septic tank. 3.0 Soil absorption system: 3.1 The soil absorption system shall be constructed by excavating the surficial loam and silt strata to expose the top of a slightly silty sand stratum at a depth of approximately 7.5 feet in the vicinity of test hole #1, near the downhill side of the bed. Due to the 27% average slope, the depth of excavation along the uphill side of the bed will be approximately 12 feet. 3.2 The bottom of the excavation shall be level. Any compacted or smeared surfaces shall be raked to provide proper infiltration. 3.3 A total of 1.0 feet of approved sewer gavel shall be placed in the bottom of the excavation with the perforated distribution pipes laid level such that the pipe inverts are no less than 6 inches above the bottom of the sewer gavel. Sewer gavel shall be 0.5" - 2.5" screened gavel, with less than 3% passing the #200 sieve. 3.4 Monitor tubes and cleanout pipes shall be of 4" diameter and installed in the locations shown on the design drawings. The portion of the monitor tube extending through the sewer gavel shall be perforated. 3.5 Approved filter fabric shall be placed over the entire top surface of the sewer gavel before backfill with unclassified soil. The top surface of the cover material shall be raised a minimum of one foot higher than the surrounding terrain to allow for subsequent settlement, and shall be graded to smooth contours. All areas disturbed by the construction shall be covered with a minimum of 4 inches of approved topsoil and neatly graded. Fill slopes shall be no steeper than 3:1. 3.6 The owner shall be responsible for revegetation of all disturbed areas to prevent erosion. 4.0 Inspections: 4.1 A total of 4 engineering inspections will be required during the course of the project: (1) initial stakeout with the contractor to establish the location of the system and to discuss the plans, specifications . and construction procedures, (2) after the native material has been excavated to expose the infiltrative surface to ensure that it is level and at the right elevation, and conforms with the soil test information, (3) after the sewer gavel is in place and the distribution pipes have been laid and connected up to the septic tank, but prior to placement of insulation or filter fabric, and (4) after final backfill and grading is complete. The septic tank requires one inspection after it is set level and the piping connected, but prior to backfill. This inspection may be incorporated with any of the above inspections. 4.2 The installer shall coordinate the timing of the inspections with the engineer sufficiently far in advance to ensure the availability of the engineer.

I further verify that. based on the information obtained from the Municipality of Anchorage flea and from my investigation and inspection, the on-site water supply and/or wastewater disposal system is(are) in compliance with all applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation. - In conducting an adequacy test, I attempt to provide a thorough, conscientious engineering analysis of the system in accordance with MoA COSA guidelines and regulations. The 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 servedbythe system. These conditions are outside the control of the evaluator of this system. All systems eventually fail and satisfactory test results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments. Therefore we cannot provide any warranty for future performance, nor can we estimate remaining life of the system.
