ANCHORAGE, ALASKA 99516 The purpose of this letter is to provide the required design narrative in support of our application for a permit to upgrade the wastewater disposal facilities on Tract "A', McHenry S/D to 5 -bedroom capacity from its present 3-bedroon capacity. Soils logs, perc test results, a site plan, design drawings and specifications are enclosed for your review. The proposed upgrade will be constructed in the vicinity of test hole # 1. As can be seen from the soil log, the native material below 2' is clean sand with a measured perc rate of less than 1 minute per inch. Using the soil application rate of 1.2 gpd/sq. ft. specified in the wastewater ordinance, this 2 bedroom upgrade requires a total absorption area of (2 x 150)/1.2 = 32 square feet. The proposed 32 foot long trench design with an effective gravel depth of 4 feet has a total absorption area of 256 square feet. The topography of the lot is generally level. A splitter valve will be installed to divide the flow between the existing drainfield and the upgrade trench. A site for ultimate replacement of the 5 - bedroom system 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, 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 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 existing 1000 gallon septic tank and double cleanout may be retained in service. The existing discharge line leading into the end of the existing drainfield shall be cut off and capped. Any existing septic tank which is not retained in service must be properly abandoned by thoroughly pumping, removing the top and backfilling with soil. 2.2 The new 500 -gallon, single -compartment septic tank shall be Municipally approved and shall be set level on undisturbed soil. It shall be equipped with a watertight manhole cover and a 4" cleanout. The tank shall be designed by the supplier for burial with 10 feet of soil cover. 2.3 All pipe connections to the tank shall be equipped with waterproof mechanical couplings. 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, with a "Zabel " flow splitter installed in between the cleanouts to divide the flow evenly between the existing drainfield and the upgrade trench being constructed. 3.0 Soil absorption system: 3.1 The soil absorption system shall be constructed by excavating a 32 foot long trench to a total depth of 15 feet below ground surface. The native sand that will be encountered maybe unstable and appropriate safety provisions must be undertaken to protect the safety of workers in the trench. 3.2 The bottom of the excavation shall be level. The sidewalls above the level of the top of the sewer gravel should be sloped back as necessary to prevent their collapse. 3.3 A total of 4.5 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 4.0 feet above the bottom of the sewer gravel. Sewer gravel shall be 0.5" - 2.5" screened gravel, with less than 3% passing the #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. 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. 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.

Name of Firm: Garness Engineering Group, Ltd (GEG) Phone: 907-337-6179 Address: 3701 East Tudor Road, Suite 101- Anchorage Alaska 99507 Engineer's Printed Name: Jeffrey A. Garness Date: L to Z i In conducting this evaluation, GEG provided an engineering evaluation of the well and/or septic system in accordance with the guidelines and regulations established by the Municipality of Anchorage and industry practices. The reported results describe the condition of the system/s on the date/s of the evaluation. Separation distances were measured to readily identifiable features. Hidden defects or encroachments may exist that were not identified during the evaluation. The operational life of all wells and septic systems depend upon a variety of variables, including but not limited to, soil conditions, groundwater levels (that may fluctuate during the year), quality of construction (materials and workmanship), and the water usage of the family utilizing the system/s. These conditions can vary, and are outside the control of GEG. Satisfactory test results do not guarantee future performance of the system/s; therefore, GEG makes no warranty (express or implied) regarding the future performance of the well or septic system. GEG makes no representation whether an alternative well or septic system can be installed on the property in the event either of the current systems fail to perform adequately in the future. The content of this report is for the sole benefit of the person/party that retained GEG to perform the evaluation. Reliance upon the information provided in this report by any other person or party (including subsequent property purchasers) is not authorized, nor will it confer any legal right whatsoever. 6.

The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 ug/L for public drinking water systems. While private wells are not subject to this regulation, EPA standards are based on existing health information and can therefore be used to gauge the relative quality of water from private wells. Information on arsenic is available from the On‐Site Water and Wastewater Program website (www.muni.org/onsite) or at 343‐7904. This advisory must be attached to all copies of the subject Certificate of On‐Site Systems Approval.
