Box 19-6650 Anchorage, AK 99519 Dear Sus: The purpose of this letter is to provide the required design narrative in support of our application for a permit to construct water supply and wastewater disposal facilities on Lot 4, Block 3, Spendlove View Heights S/D located on Spendlove Drive. Soils logs, perc test results, a site plan, design drawings and specifications are enclosed for your review. The proposed wastewater disposal 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 18 feet below ground surface is a gray silty sandy gravel with a measured perc rate of 19 minutes per inch. Using the soil application rate of 0.6 gpd/sq, ft. specified in the wastewater ordinance, this proposed 3 bedroom residence requires a total absorption area of (3 x 150)10.6 = 750 square feet. The proposed 75 foot long trench design with 5 feet of sewer gravel below the horizontal distribution pipe has a total absorption area of 750 square feet. Because seasonal groundwater levels of 13 feet below ground level were measured in both test holes last fall (although both were dry when rechecked this spring) the bottom of the trench excavation was set at 8 feet below ground surface. The topography of the lot in the vicinity of the proposed construction slopes towards the southwest at approximately 10%. A site for a possible replacement soil absorption trench with similar dimensions is shown on the site plan. 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, �� 2 _ Ted Moore, P.E.

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. 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. 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 1000 gallon, 2 compartment septic tank shall be Municipally approved and shall beset 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. 2.2 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, 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 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 an 8 foot deep by 75' long trench in the approximate location shown on the site plan, with the axis of the trench parallel to the natural contour of the land. 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 5.5 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 5.0 feet above the bottom of the sewer gravel. Sewer gravel shall be 0.5" - 2.5" screened gravel, with less than 3% passing the 0..00 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 12 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 minimum 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 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 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, FLATTOP TECHNICAL SERVICES 14530 ECHO ST.
