ANCtIORAGE, ALASKA 99516 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 Parcel 1, SE 1/4, Section 31, T12N, R2W, S.M., located at 14936 Hiland Road in South Anchorage. The existing 2-bedroom residence is presently served by a legally permitted pit priW. Soils logs, perc test results, a site plan, design draxvings and specifications are enclosed for your review. The proposed system will be constructed in the vicinity of test hole # 1. As can be seen from the soil log, the native material between 1 and 4 feet below ground level is a sandy silty gravel with a measured perc rate of 4 minutes per inch. Solid bedrock does not occur until below 10.75 feet. Using a conservative soil application rate of 0.8 gpd/sq, fl., this 2-bedroom residence requires a total absorption area of(2 x 150)/0.8 = 375 square feet. The proposed 63-foot long trench design with an effective gravel depth of 3 feet has a total absorption area of 378 square feet. The topography of the lot in the area of proposed construction slopes down towards the west- southwest at 37%. As I discussed with Dan Roth earlier this month, the slope is uniform and has no · breaks in slope that would promote the daylighting of effluent. The test holes were dug shortly after breakup and I carefully xvalked the area downhill of the proposed absorption trench to verify the absence of any evidence of natural daylighting. Also, at the suggestion of Dan Roth, I arranged to have a third test hole dug 50 feet directly doxvnslope of the proposed system to verify the continuity of soils in this area. The soils underlying the proposed absorption stratum are an angular silty gravel that has good permeability and therefore should allow effluent leaching into the ground from the proposed trench to remain below the ground surface. Because of the steepness ofthe existing ground, the fill slope ofthe cover material will need to be 2:1 instead of the normal 3:1. The proposed project will have no significant impact on present or future water supply and wastewater disposal systems serving adjacent properties, nor ~vill it have any significant impact on reserved space-surface and subsurface, or on drainage. Please give me a call at 345-1355 if you have any questions on this submittal. Sincerely, Ted Moore, P.E. UNSUBDIVIDED SITE FOR REPL. TRENCH #3 63-FOOT LONG ~ SOIL ABS.

During construction special care will have to be taken because ofthe steep slopes characteristic of this lot. Prior to the start ofconstruction the homeo~vner shall arrange with a surveyor to mark the property boundary along Hiland Road to that a suitable well site can be identified with the required 100-foot separation from the proposed septic tank and absorption trench. 1.2 Construction shall be as depicted on the approved site plan and design drawings. Minor deviations from these drawings may be allowed or required by the engineer conducting the inspections. All construction procedures and material specifications shall conform to Municipal and State requirements. All separation distances shall be in conformance with Municipal requirements, unless specifically waived. 1.3 The contractor shall be responsible to obtain any necessary utility locates, and to work around any buried utilities. 1.4 The contractor shall provide adequate cover material and rough grading over all system components to ensure that proper drainage is achieved after settlement and that there are no residual depressions. Insofar as possible the contractor shall minimize damage to trees and existing lawn areas. 1.5 Unless specifically agreed otherwise, the homeo~mer shall be responsible for finish grading after the soil is compacted, as well as placement of topsoil and reseeding all areas disturbed by the construction. 2.0 Septic Tank: 2.1 The new 1000-gallon, 2 compartment septic tank shall be Municipally approved and shall be set level on undisturbed soil. Each compartment shall be equipped with a watertight manhole cover and a 4" cleanout. Ifthe tank is buried less than 4 feet, it shall be insulated with 2 inches of approved burial type, rigid insulation. 2.2 All pipe connections to the tank shall be equipped with ~terproof 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 1/8" per foot. A cleanout shall be installed 1 - 4 feet from 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 a 63-foot long trench to a maximum depth of 4.7 feet below ground level on the high side of the trench. The long axis ofthe excavation shall parallel an existing contour. The trench width shall be no greater than 2.0 feet. 3.2 The bottom of the excavation shall be level. Any compacted or smeared surfaces shall be raked to allow proper infiltration. 3.3 A total of 3.5 feet of approved sewer gravel 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 3.0 feet above the bottom ofthe sewer gravel. Sewer gravel shall be 0.5" - 2.5" screened gravel, with less than 3% passing the/t200 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 gravel shall be perforated. 3.5 Approved filter fabric shall be placed over the entire top surface of the sewer gravel. A minimum of 2 feet of soil cover is to be placed over the filter fabric. If the soil cover thickness is less than 3 feet, two inches of rigid, burial type insulation is to be placed over the entire top surface of the gravel, in addition to the filter fabric. 3.6 The top surface of the cover material shall be raised a minimum of 6 inches higher than the surrounding terrain to allow for subsequent settlement, and shall be graded to smooth contours. Fill slopes shall be no steeper than 2:1. 3.7 Unless specifically agreed otherwise the homeowner shall be responsible for arranging to have the site finish graded after the backfill material has stabilized, and for placement of adequate topsoil and seed to promote rapid revegetation ofall areas disturbed by the construction. 4.0 Inspections: 4.1 A minimum of 4 engineering inspections will be required during the course of the project: (I) 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 gravel 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 rough 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 ofthe 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.
