Box 19-6650 Anchorage, AK 99519 Dear Sirs: This is the requked design nan'ative to accompany the sewer upgrade permit application for Lot 7, Block "D", Knik Heights S/D. Copies of the soil test results and and design drawings are enclosed. The proposed upgrade is from 4 to 6 bedrooms. The existing soil absorption trench was sized and approved for 4 bech'ooms at the time of it's construction in 1984, and in 1991 the fluid depths were consistent with a normally operating septic system. The proposed trench upgrade will provide two bedrooms worth of additional capacity. To upgrade the existing 1250 gallon septic tank to six bedroom capacity would require the addition of another 500 gallon septic tank, however our measurements indicate that the existing tank is only 96 feet from the well. Rather than apply for a waiver, or try to move the 7 yea' old tank, we intend to replace it with a new 2000 gallon septic tank located outside the 100 foot radius from the well. As can be seen from the soil logs, the subsurface soils are excellent for construction of a soil absorption system. The soil rating based on the measured 3.6 minutes per inch in test hole #2 is 1.2 gpd/sq, ft., which for a two bedroom upgrade requkes 300/1.2 = 250 square feet of sidewall at'ea. To obtain this, while optin-dzing usage of the best material, we have designed a 25 foot long deep trench in the vicinity of test hole #2, with the sewer gravel beneath the disn'ibution pipe extending between 8' and 13 feet. On the site plan we have designated a 75 foot long replacement ~ench with a 20 foot gap spanning the area of the presently proposed upgrade. This is only one conceptual plan, and the lot size coupled with the good soil conditions demonstrated by the test holes allows for many options. The topography in the proposed construction area slopes gently to the southwest at approximately 5%. There is no observed surface drainage within 100 feet of the existing or proposed system. The proposed project will have no measurable impact on wells or wastewater disposal systems on adjoining lots. ,Nor will it have any impact on reserved space/surface and subsurface, or on di'ainage. Please give me a call if you have any questions on this design. Sincerely, Ted Moore, P.E. Flattop Technical Services 14530 Echo Street, Anchorage, AK 99516 Phone (907) 345-1355 Lot 7, Block "D", Knik Heights S/D 12700 Atherton Rd. Wastewater disposal system installation Specifications 1.0 General: 1.1 The scope of the project includes replacement of an existing 1250 gallon septic tank with a new 2000 gallon septic tank and construction of a 25 foot long soil absorption trench with 5.5 feet of sewer gravel to supplement the existing soil absorption system. 1.2 Construction shall be as depicted on the approved site plan and design di'awings. Minor deviations from these di'awings may be allowed or required by the engineer conducting the inspections. All construction procedures and material specifications shall conform with Municipal and State requh'ements. 1.3 All separation distances shall be in confom~ance with Municipal requirements, unless specifically waived. 1.4 The contractor shall be responsible to obtain any necessm'y utility locates, and to work around any buried utilities. 2.0 Septic Tank: 2.1 The existing septic tank is to be abandoned by pumping, removing, crushing and burying on site at a location outside the consU'uction area and more than 100 feet from all wells. A new 2000 gallon septic tank is to be installed at the approximate location shown, with pm'ticular care being taken to ensure that all portions of the tank m'e mom than 100 feet from the well. 2.2 The 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, mid the waste line between the tank and the soil absorption system shall have a minimum slope of 1/8" per foot. A double cleanout shall be installed within 5 feet downstream of the septic tank. 3,0 Soil absorption system upgrade: 3.1 The soil absorption system upgrade shall be coustructed by excavating a trench in the approximate location shown to a depth of 13 feet. The beginning of the trench shall be no closer than 5 feet from any portion of the existing n'ench. 3.2 The bottom of the new trench excavation shall be level. Any compacted or smeared surfaces shall be raked to allow proper infiltration. 3.3 A total of 5.5 feet of sewer gravel shall be placed in the trench, with the bottom of the horizontal distribution pipe set level 5 feet above the bottom of the gravel. Sewer gravel shall be 0.5" - 2.5" screened gravel, with less than 3% passing the #200 sieve. The perforated distribution pipe in the existing trench shall be disconnected from the existing sump and rerouted around the sump, with the sump remaining as a monitor tube in fire existing trench. The perforated distribution pipe linking the two trench segments shall incorporate a 2" bump (rise) in the line before descending to the level of the second trench. Approximately 12 inches of sewer gravel shall be placed beneath the perforated pipe linking the two lreuch segments. 3.4 Monitor tubes and cleanout pipes shall be of 4" diameter and installed in the locations shown on the design ch'awings. The portion of the monitor tube extending through the sewer gravel shall be perforated. 3.5 Approved filter fabric shall be placed over the entire top surface of the sewer gravel before backfill. 3.6 The top surface of the cover material shall be mounded 6 inches higher than the sun'ounding ten'ain to allow for subsequent settlement, and sh,'dl be graded to smooth contours. Fill slopes shall be no steeper than 3:1. 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 plm~s, 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 fight elevation, and confmrns with the soil test information, (3) after the sewer gravel is in place and the distribution pipes have been laid and connected up to the septic tank, but prior to placement of 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 advm~ce to ensure the availability of the engineer.

Tudor Road Anchorage, Alaska RECEIVED Subject: Soil Investigation for Sanitary Sewer System, Lot 7, Block D, Xnik Heights Subdivision, Anchorage, Alaska Gentlemen: At your request of September 20, 1978 we conducted a subsurface soils inves~ tigation at the proposed location of the sanitary sewer system on the subject lot. The investigation complied with those procedures required by the Munic- ipality of Anchorage Department of Health and Environmental Protection. This investigation, which was accomplished on September 21, 1978 consisted of a test hole excavated to a depth of 16 feet below the existing ground surface. The test hole was sited according to your instructions and its location is shown in attached Drawing A-01. Excavation was accomplished with a backhoe. The topography at the excavation site is generally gently-sloping to the west. At the time of investigation the site had original vegetation con- sisting of spruce, birch and brush which had been partly cleared. The top of the test hole was located at original ground surface. The soils encountered in the excavation are shown in the test hole log in Drawing A-01. This log displays specific conditions encountered at the test location. However, subsurface conditions may vary in other parts of the lot without any apparent surficial evidence of the change. Groundwater was not encountered. Bedrock was not encountered and at the time the hole was exca- vated seasonal frost was not present. Based on tile visual classification of the soil and the requirements set forth by the Muncipality of Anchorage, a percolation test was not necessary within the test hole on the subject lot.
