RECEIVED BY: ISSUED BY: / DATE: TTOP TECHNICAL CIVIL & ENVIRONMENTAL ENGINEERING · ENERGY CONSERVATION & ANALYSIS THEODORE F. MOORE, P.E. 14530 ECHO ST. PH: (907) 345-1355 December 30, 1991 ANCHORAGE, ALASKA 99516 M.O.A. DHHS P.O. Box 19~6650 Anchorage, AK 99519 Dear Sirs: The purpose of this letter is to provide the requh'ed design narrative in support of our application for a permit to construct wastewater disposal facilities on Lot 2, Block 6, Mountainside Village S/D, located on Big Mountain Drive. Soils logs, perc test results, a site plan, design drawings and specifications are enclosed for your review. Although the site plan designates a location for a well, we are not applying for a well permit at this time, because the property is just in the process of being marketed. The purpose of this submittal is to obtain DHHS review and concept approval of the proposed septic system - actual construction quite possibly will not take place within the initial per,nit period. The proposed system will be constructed between test hole #5 and #7 . As can be seen fi'om the soil logs, the native material between 2' and 4.5' deep in this area is a slightly silty sandy gravel with a measured percolation rate of 1.7 minntes per inch. Bedrock was encountered at 6' below ground level in both test holes, and for design purposes a 6' bedrock depth is assumed to be applicable for the entire area encompassed by the proposed drainfields. Tile proposed system was designed using the soil application ¢--~-~f 170-~d'-/s~.-j4. specified in the wastewater ordinance fol' filter sand which will be used to achieve ~%+ s~-pm'afion between the bottom of the sewer gravel and bedu'ock. A fora' bedroom residence requires a total absorption area of (4 x 150)/1.0 = 600 square feet. The proposed design of two 5' wide drainfields having a total length of 120 feet has a total absorption area of 600 square feet. The unequal length configuration of tile design was chosen to allow futm'e installation of similarly configm'ed replacement drainfields utilizing a total of only 3 pm'allel alignments. The topography of the lot in the vicinity of the proposed drainfields slopes to the northwest at approximately 25%, with steeper slopes above. The lower edge of the ~ower replacement dramfield wall -7*be approximately 30 feet uphill fi'om the top of a 10 foot high cutbanl~ ~.~[{'l{;a~h~-l~t-'bgk Because of the good permeability characteristics of the native soils overlyin~-~h'e-~Sr~kYw-~-bT~ie~e this configm'ation will not pose a threat of effluent daylighting in the cutbank below. By the time the effluent has traveled 30 feet horizontally it will have ample opportunity to filter into cracks ill the bedrock, as is evidenced by the fact that the roadside ditch below the cutback shows no evidence of being subjected to surface flow. The design concept is quite similar to that recently utilized in the soil absorption system recently constructed on the adjacent Lot 1, Block 6, located just to the south of the subject property. To ensm'e even distribution of effluent to the two drainfields, an "Orenco" lift station w!th pressurized distribution pipes will be installed. To match the 30 gpm pump output with an average 5 residual head and flow 0.5 gpm, a total of 60 holes are to be ch'illed on 2' centers. Since the two drainfields have an elevation differential of 4', the design calls roi' 1/8" diameter holes in the lower drainfield and 5/32" diameter holes in the upper. The proposed project will have no impact on present or future water supply and wastewater disposal systems serving adjacent properties, nor will it have any impact on reserved space/surface and subsm'face, or on drainage. Please give me a call at 345-1355 if you have any questions on this submittal. Sincerely, Ted Moore, P.E. LOT TA~K W', L~FI' 5TA,. PROPOS~b '~:0' J~Nb HO~ ,PROP.

Minor deviations from these drawings may be allowed or reqnired 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, as is the case of the 30' separation between the lower reserve drainfield and the top of a cutbank. 1.4 The conta'actor shall be responsible to obtain any necessary utility locates, and to work around any buffed utilities. 2.0 Septic Tank: 2.1 The septic tank shall be a 1500 gallon Municipally approved S.T.E.P. tank with two compartments, and shall be set level on undisturbed soil. Blasting or jack-hatrnnering of bedrock may be necessary to achieve adequate bm'iai depth. Each compartment shall be equipped with a watertight manhole cover and a 4" cleanout in addition to the manhole riser giving access to the lift station pump. If the tank is buffed less than 4 feet, it shall be insulated with 2 inches of approved bm'ial type, rigid insulation. 2.2 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. A cleanout shall be installed within 5 feet of the building foundation. The pressure distribution pipe leading from the tank to the dralnfields shall be 1.25" diameter schedule 40 PVC. 3.0 Lift station: 3.1 The lift station shall be installed in the second compartment of the 1500 gallon S.T.E.P. tank shall be an "Orenco" package system as supplied by Anchorage Tank. An alternative lift station package may be substituted at the discretion of the engineer, provided it has been pre-approved by the Municipal Health Department. 3.2 The contractor shall be responsible to obtain the nes, essm'y Municipal electric pemqit and inspection, and to provide a copy of the elect~'ical inspector s report to the engineer overseeing the construction of the wastewater disposal system. 3.3 The on, off, and alm'm floats shall be set at the elevations specified by the lift station supplier, and their proper operations shall be verified by the contractor. The visible and audible alm'm box shall be mounted inside the residence. 4.0 Soil absorption system: 4.1 The soil absorption system shall be constructed by carefully stripping off the shallow peat and silt loam slxata along alignments paralleling the natural contours of the ground to expose the top of a slightly silty sandy gravel stratum. The snipping width shall be 9' wide and the two drainfields with a combined length of 120 feet shall be spaced 15' on center. 4.2 The bottom of the stripping excavation will not be level. The bottom of the excavation shall not be driven on, and any compacted or smeared surfaces shall be raked to ensure proper in£fltration. The sand utilized for leveling and filter material shall comply with Municipal specifications. Sufficient sand shail be placed in the excavation to create a 5' wide level compacted surface at the elevation of the original gq'ound level on the uphill side of the excavation. 4.3 Prior to placement of sewer gravel, it will be necessary to create a containment berm of less permeable soil over the sand, particularly on the downhill side of the ch'ainfield. A total of 9 inches of approved sewer gravel shall be placed on top of the sand. Sewer gravel shall be 0.5" - 2.5" screened gq'avel, with less than 3% passing the #200 sieve. The 1.25" diameter schedule 40 PVC perforated distribution pipes laid level such that the pipe inverts are no less than 6 inches above the bottom of the sewer gravel. Holes shall be drilled on 2' centers in the bottom of each distribution lateral, with the holes in the lower drainfield being 1/8" diameter, and the holes in the upper ch'ainfield being 5/32" diameter. All PVC pipe joints in the discharge and distribution pipe network shall be glued and the ends capped. 4.4 Monitor tubes 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. 4.5 Approved filter fabric shall be placed over the enth'e top surface of the sewer gravel in addition to 2" of rigid burial type insulation. A minimum of 2 feet of soil cover is to be placed over the filter fabric. 4.7 The top surface of the cover material shall be raised a minimum of 6 inches higher than the sun'ounding terrain to allow for subsequent settlement, and shall be graded to smooth contours. Fill slopes shall be no steeper than 3:1. 4.8 All areas disturbed by the construction shall be covered with 4 inches of topsoil and seeded with an approved gq'ass seed to promote rapid revegetation. The owner shall be responsible for ensuring that the grass does grow. 5.0 Inspections: 5.1 A total of 5 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 conforms with the soil test info~vnation, (3) after the sand leveling and filter material has been placed, (4) after the sewer gravel is in place and the dista'ibution pipes have been laid and connected up to the septic tank, but prior to placement of insulation and filter fabric, and (5) after final backfill and grading is complete. The septic tank requires one inspection after it is set level with the lift pump and the piping connected, but prior to backfill. This inspection may be incorporated with any of the above inspections. 5.2 The installer shall coordinate the timing of the inspections with the engineer sufficiently far in advance to ensure the availability of the engineer.
