Box 19-6650 Anchorage, AK 99519 Dear Sirs: The purpose 6fthis letter is to provide the required design narrative in support of our application for a permit to construct waste~vater disposal facilities on Lot 3 of Shangri-La S/D, located on Sandpiper Drive. Soils logs, perc test results, a site plan, design drawings and specifications are enclosed for your review. The prop6~ed system will be constructed in the vicinity of test hole # 1. As can be seen from the soil log, the native material between 3.5 and 12 feet is a clean sandy gravel with a measured perc rate of less than one minute per inch. Despite the rapid pere rate, the presence of sand between 12 and 18.5 feet should provide adequate filtration of septic tank effluent to avoid the necessity of installing a sand filter. Using the soil application rate of 1.2 gpd/sq, ft. specified in the wastewater ordinance, this proposed 4- bedroom residence requires a total absorption area of(4 x 150)/1.2 = 500 square feet. The proposed 40- foot long trench design with an effective gravel depth of 7.5 feet has a total absorption area of 600 square feet. The topography of the lot in the area of proposed construction slopes do~m towards the north at approximately 5%. The proposed project will have no significant impact on present or future water supply and wastewater disposal systems serving adjacent properties, nor will 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. SITE FOR SIMILAR ...................................

Minor deviations from these drawings may be allov~ed 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 confo,mance 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 homeowner 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 1250-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. 2.3 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 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. All portions of the sewer line that pass under the driveway and parking areas shall be insulated with 4 inches of rigid, burial type foam insulation. 3.0 Soil absorption system: 3.1 The soil absorption system shall be constructed by excavating a 40-foot long trench to a depth of 12.0 feet below original ground level. Ifthe alignment ofthe trench does not follow an existing contour of the land, the maximum depth of the trench at the south end shall be 12.5 feet. 3.2 The bottom of the excavation shall be level. Any compacted or smeared surfaces shall be raked to alloxy proper infiltration. Sand for leveling or serving as filter material shall comply with Municipal specifications. 3.3 A total of 8.0 feet of approved sewer gravel shall be placed in the bottom ofthe excavation with the perforated distribution pipes laid level such that the pipe inverts are no less than 7.5 feet above the bottom of the sewer gravel. Sewer gravel shall be 0.5" - 2.5" screened gravel, 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 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 3:1. 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 of all areas disturbed by the construction. 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 ofthe 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 ofinsulation 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 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.
