Box 196650 Anchorage, Alaska 99519-6650 Ref: Proposed and Well Septic System Design for Alyeska Basin Subdivision Unit 7 Tract B-3. ADVANTEXTM TREATMENT SYSTEM To whom it may concern: The proposed 4 bedroom house will be served by a private well and septic system. Two test holes were excavated on the property. The drainfield will be designed around the 30 foot radius of these test holes. Due to the presence of high ground water and the owners desire to minimize environmental impact, we are proposing to utilize a Class III Advantex system. Comments regarding the proposed design are summarized as follows: DRAINFIELD APPLICATION RATE: Percolation tests were performed between 3.0 to 3.5 feet and the rate was determ'med to be between 3.3 and 13.3 minute/inch. Given this percolation rate, the effluent from a Class III Advantex system has an allowable application rate of 5.0 GPD/FT2. To be conservative, the proposed system will utilize an application rate of 3.0 GPD/FT2. 2. TRENCH DESIGN: a. Percolation Rate: 13.3 & 3.3 minutes/inch b. Proposed Application Rate: 3.0 gallons/day/~ c. Number of Bedrooms: 4 d. Design Flow: 600 gallons per day e. Minimum Absorption Area: 200 fla f. Total Depth: 1.5 feet (Remove organics) g. M.O.A. Approved Sand Filter Depth: 2 feet h. Effective Depth: 0.5 feet i. Width: 5 feet j. Minimum Length: 40 feet long 6901 Debarr Road, Suite 2B * Anchorage, AK 99504 Ph: (907) 337-6179 * Fax: (907) 338-3246 * Website: akwwc.com k. Effective absorption area: 200 fl2 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed design. 4. TOPOGRAPHY: The area for the proposed septic system is on a roughly 12 percent slope. The proposed dralnfield will be installed parallel to slope contours. We are unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you hav. e/lany questions, please contact ns at 337-6179. Thank you for your assistance.

The design is for a four ( 4 ) bedroom residence H. DEFINITIONS: 1. Property owner or homeowner: The legal property owner or his/her appointed representative (not AKWWC, Inc.). 2. Engineer: Alaska Water & Wastewater Consultants, Inc. (AKWWC, Inc.) 3. Contractor: The company hired by the property owner to install the septic system. If the property owner installs the system then be/sbe would also be the contractor for purposes of this installation. 4. Well Driller: The person or company hired by the property owner to drill the well. $. DSD &/or MOA: Municipality of Anchorage, Development Services DepaCunent, On-Site Water & Wastewater Program. IH. RESPONSIBILITIES: Property Owner Responsibilities: 1. CONTRACTUAL RELATIONSHIP: The properW owner shall con~act with the contractor to perform the work outlined in these specifications and plans, in accordance with the attached DSD permit. There is no contractual relationship between the contractor and the engineer. The engineer shall inspect the work, as required by DSD, so as to document the installation. Final acceptance of the contractor's work rests with the owner and the DSD. 2. SINGLE FAMILY RESIDENCE ONLY: This well and/or septic system design is for a single family residence only. The homeowner is responsible for notifying the engineer if the residence is used as a duplex, business, or multi-family dwelling. In such cases, the installation permit must be obtained from the State of Alaska, DeparUnent of Environmental Conservation. 3. DISCLAIMER REGARDING AS-BUILT SURVEY: The validity of the design site plan is limited by the accuracy of the ns-built survey provided to the engineer by the proper~ owner or his/her representative. The property owner shall notify the engineer regarding any known inaccuracies nssociated with the as-built survey. The engineer assumes no responsibility for the accuracy of the survey. 4. UNPLATTED EASEMENTS: The property owner is responsible for notifying the engineer and the con~a'actor of any unplatted easements, not shown on the as-built survey, which the new well or septic system may encroach into. Such easements are typicaliy identified in the properW title report. 5. DISCLOSURE OF SITE CONDITIONS: The prope~o~ owner shall notify the engineer and the con~ractor of any seasonal groundwater or surface water runoff conditions known to him/her which could potentially effect the operation of the septic system. The proposed septic system must be at least 100 feet from any streams, ponds, creeks, swamps, bogs, or any other surface water as defined by the DSD. This disclosure is of particuiar significance when the site evaluation and design work is being done during the winter months when surface waters are frozen and there is snow cover. Page 1 of 7 AKF~YC, Inc., Year 2002 The property owner shall notify the engineer and the contractor of any known subsurface conditions that would prohibit or restrict the installation of the septic system. Items of concern would include, but are not limited to buried piles of construction debris, undocumented septic systems, areas which consist primarily of fill (imported) soil, subsurface drainage systems, & abandoned wells. 6. DRINKING WATER WELLS: The property owner is responsible for notifying the engineer if, to his/her knowledge, any of the adjacent properties are used as a duplex, business, or multifumily dwelling. The new septic tank end leachfield must be at least 100 feet from any private well, 150 feet from any class "C" well, and 200 feet from any class "A" or "B' well, unless appropriate waivers are obtained. Furthermore, the property owner shall notify the engineer of any undocumented or abandoned wells, known to him or her, that are located on the subject or adjacent properties. 7. CURTAIN DRAINS: The new drainfield must be at least 20 feet down gradient and 50 feet upgradient from any subsurface drains. This inchidas foundation drains. The property owner should notify the engineer of any such drains that are not shown on the design drawings for this installation. 8. POST CONSTRUCTION SITE RESTORATION: Unless specifically agreed upon otherwise, the property owner is responsible for final grading of the areas which settle afier construction. Prior to awarding the contract, the homeowner should communicate to the contractor any expectations regarding, but not limited to post construction site cleen-up, re-lendscaping, and restoration of any asphalt, fences, ~'eas, decks, ect. that are effected by the construction. All mound type drainfields are required by the MOA to be re-vegetated. The property owner is responsible for this work unless other arrangements are made with the contractor. If the property is being sold, the property owner shall ensure that the aforementioned items are addressed] with the buyer, and, if the work is to be completed aRer the sale of the property, that necessary funds are[ escroWed to fund the completion of the work. ! 9. PROPERTY OWNER INSTALLATION OF SEPTIC SYSTEM: If the property owner intends to install the septic system be/sbe must first have obtained approval from the Municipality of Anchorage, DSD (343-7904). Homeowner installations typically require more time for engineer inspections. The homeowner should discuss the additional costs associated with such inspections with the engineer prior to starting the project. 10. ENGINEER CHARGES TO INSPECT THE INSTALLATION: The property owner is responsible for payment of all the engineer inspection charges. These charges are in addition to the soils testing end design work that was required to obtain the MOA sewer/well permit. The number of inspections will vary depending on the actual field conditions encountered and the construction methods used. If there are eny questions by the properVy owner, or Ms/her representative, regarding charges for installation inspections they should be discussed prior to beginning construction. AKWWC, Inc. will provide you with a written copy of the fee schedule. 11. CHANGES IN THE SCOPE OF WORK: See Section V, "Disclaimers" regarding design changes. See "Contractor Rasponsibdlue , paragraphs 1, 2, & 13. In addition, see "Engineer Responsibilities", paragraphs 2, 4, & 5. Contractor Responsibilities: 1. PRE-CONSTRUCTION LAYOUT: The contractor is responsible for locating all buried utilities, easements, property lines, surface water setbacks, well radii, and water service fines which may be encroached upon by the proposed septic system. The contractor shall ensure that all setbacks are flagged by a registered land surveyor, or other appropriate meens, prior to construction. AKWWC, Inc. field engineers/inspeetors will not be responsible for establishing or confirming any of the aforementioned setbacks. The contractor should recognize that the location of all wells, surface waters, structures, and other items[ shown on the design drawings are typically derived from as-built surveys, and municipal records. The Ibuilt surveys and municipal records (prepared by professional engineers & lend Surveyors) have been[ [assumed to be accurate for purposes of this design; however, the accuracy has not necessarily been field[ [verified. Prior to beginning eny construction the contractor shall field locate all items which .h~.vel [protective setbacks and verify that there are no encroachment concerns. Any encroachments, for which[ Page 2 of 7 AKVgWC, Inc., Year 2002 waivers have not been granted, should immediately bo brought to the attention of thc prop~ owner (or[ their representative) and the engineer. I The test hole pipes shall not be removed/abandoned until after the engineer has established their location relative the new drainfield during the first inspection of the drainfield installadon or during the pre- construction layout. The new drainfiald/s must bo within a 30 foot radius of the test hole/s used for establishing the design criteria. The contractor should establish the elevation of all existing and proposed system components prior to[ starting construction so as to insure that the necessary grades can bo maintained. This is particularly[ significant when the elevadon of the existing system components is unknown because clean-outs are not[ present, buried, or non-funclional (can't measure down them because of obstructions). It is recognized that[ condilions can be discovered that will materially chan~e the design and the construction costs. 2. DISCREPANCIES BETWEEN DESIGN DRAWINGS AND SPECIFICATIONS: Construction shall be in accordance with the approved site plan and design drawings, and any special provisions noted on the municipal sewer permit. The contractor is responsible for notifying the engineer of any discrepancies noted on the design plans or drawings, prior to starting work. 3. CHECK GROUNDWATER LEVELS IN TEST HOLE MONITORING TUBES: Prior to beginning construction, the contractor shall check the liquid level in the test hole monitoring tubes to ensure that there has been no change in the groundwater levels that would impact the proposed design. Any rise in the liquid level should be brought to the attention of the engineer so that design changes can bo made if necessary. 4. MAXIMUM DEPTH OF DRAINFIELDS: The maximum depth of the drainfield is shown on the design drawings or is noted in the narrative portion of the design package. The contractor shall notify the engineer of any inconsistencies noted in the design package. For purposes of this installation, the maximum depth of the drainfield will be based upon taking a] measurement at the deepest part of the excavation between the highest ground elevation encountered[ (usually on the uphill side of the excavation) and the bottom of the trench or bed excavation. The[ contractor shall exercise cautiOn not to remove evidence of the original grade prior to establishment of the total system depth. In short, don't remove the organic layer until after the original grade elevations are[ established by the inspectin~ engineer. S. SUITABILITY OF MATERIALS USED FOR CONSTRUCTION. The contractor shall ensure that all materials being used are in compliance with the most current guidelines established by the Municipality of Anchorage. This includes, but is not limitedto, the following: a. Drainrock b. Sand filter material for conventional beds, trenches, or mound systems. c. Sand filter material and pea gravel for Intermittent Send Filters (ISF). d. Anchorage Sand and Gravel (AS&G) "block pea" material for Upflow Filters.

INNOVATIVE SEPTIC SYSTEMS. START-UP INSPECTIONS:The contractor shall notify Anchorage Tank & Welding Company (272-3543) after the installation of an Intermittent Sand Filter kit or Advuntex system (supplied by Anchorage Tank) is installed so that the appropriate start-up inspection can be scheduled. This notification also activates the quarterly maintenance schedule. Such notification is usually not required for BioCycle installations since "BioCycle of Alaska" is typically involved with the installation. The contractor shall contact BioCycle of Alaska (283-9003) regarding any start-up notification requirements. Well Driller Responsibilities: 1. Tho well driller shall ensure that he has a well permit in possession prior to drilling the well. 2. The well driller shall physically verify that the there are no septic systems, or other potential sources of contamination, within the protective radius of the proposed well prior to drilling it. Engineer Responsibilities: 1. SYSTEM DOCUMENTATION: The engineer is responsible for inspecting the installation of the septic system and preparing as-built documentation, to the satisfaction of the M.O.A.. Inspections are performed as necessary to document the construction of the system to the satisfaction of the M.O.A. In all cases, inspections shall be performed as necessary ~ establish the following: * The original grades at the dralnfield/s site * The bottom of all ~'eoch/bed excavation * Top of sand on all sand filters * Top of drainpipe * Septic tank, or lift station, or holding tank prior to backfill * Placement of filter fabric and insulation Page 4 of 7 AKWWC, Inc., Year 2002 * Ai~er final grading is completed 2. LIMITED AUTHORITY: The inspecting engineer has no direct authority over the conlxactors activities or conslxuction/safety practices. Should the engineer identify conditions which dictate a design change, he or she will recommend that work be stopped, and/or the design be modified. If design modifications are necessary, the engineer shall notify the property owner or his/her representative. The inspecting engineer does not have the authority to direct the contractor to modify the system design in such a way that it would be in violation of State or MOA regulations. 3. SEPTIC TANK INTEGRITY: The engineer shall inspect the condition of the existing septic tank and determining its suitability for re-use. If the engineer determines the septic tank to be structurally unsound, it must be replaced. 4. COORDINATION OF DESIGN CHANGES WITH THE MOA: If design changes are necessary, the engineer will coordinate the approval of the changes with the MOA. The contractor does not have the authority to proceed with any design modifications until verbal or written approval is obtained from the MOA. 5. COORDINATION OF WAIVERS: If, during construction, it is determined that a waiver will be required in order to install the system as designed, the engineer will apply for the necessary waiver/s to the appropriate State or MOA regulatory bodies. The engineering services and State/MOA fees associated with such waivers will be additional charges to the property owner, over and above the installation inspection fees charged by AKWWC, Inc. SECTIONIE CONSTRUCTIONGUIDELINES: Construction shall be in accordance with the approved site plan and design drawings and any special provisions noted on the municipal well and/or sewer permit. All materials, components, workmanship, and construction practices shall comply with the Municipality of Anchorage's latest ordinances regarding wells and septic systems, as well as DSD policies. The failure of the insoectino ens,ineer to notice a material or ¢onslruction non-compliance does not relieve the contractor of his/her resnonsibilitv to correct such a deficiency. ~ Septic Tank, Holding Tank, or Lift Station Installation: 1. The burial rating of the tank shall be adequate for the actual burial depth encountered. 2. The tank shah be level and sufficiently bedded to prevent settling or shifiing of the tank. 3. All standpipes on the tank shall extend a minimum of 12 inches above final grade. 4. Tanks installed with less than 4 feet of cover shall be insulated. See "Contractor Responsibilities", paragraph 12 regarding final soil cover. 5. The sewer service line from the house to the tank shall be sloped a minimum of 1/4" per foot, unless prior approval is obtained from the engineer. 6. The inlet and outlet lines from the tank shah be bedded in drainrock or the soil shall be adequately compacted to prevent future settlement of the soil. 7. A foundation clean-ont will be installed ( 1-4 feet from the house) ifune does not currently exist. 8. Post tank clean-outs shall be installed per MOA requirements. Does not apply to holding tanks or lift stations with pressurized lines. 9. In high groundwater areas, all tanks shall be anchored to resist buoyancy forces when there is not adequate soil cover to resist the uplift force. The engineer shall make this determination. 10. The final soil cover shall be graded so that there is positive drainage away from tank. 11. All holding tanks and Hft stations shall have an audible and visible alarm inside the residence. 12. All li~ stations shall be wired in compliance with ail MOA guidelines and the Uniform EleeUical Code. A municipal clec~cai permit and inspections must be obtained in areas where required by the Municipality of Anchorage. 13. The contractor shall remove the old tank, or abandon it in compliance with the Uniform Plumbing Code (UPC). The contractor is solely responsible for the abandonment procedure. 14. ISF AND ADVANTEX INSTALLATIONS: The control panel for the Intermittent Sand Filter and Advantex systems shall be located outside the residence, for easy access during inspections. A Page 5 of 7 AKWtVC, Inc., Year 2002 ramote alarm must be installed inside the residence as per DSD requirements. Mounting the panel directly to an exterior wood wall should be avoided because the closing of the relays creates. a "clanking" noise that may be offensive to the property owners. 15. ISF INSTALLATIONS: The air compressor shall be equipped with 0 to 10 psi gauge for the purpose of monitoring air flow to the sand filter. The pressure gauge will be located so that it is easily monitored by the property owner. ~ Installation of Conventional Absorption Bed & Trenches: 1. Excavate the proposed bed/trench to the dimensions shown on the design. The bottom of the excavation shall be within 2 inches of level (2 inch maximum variation between high and low spots). If the sidewalls or bottom of the excavation become smeared, they must be raked or scarified before placement of the filter sand or drainrock. 2. The trench or bed should be at least 5 feet from the test hole excavation. 3. All soil tests and excavation depths are advisory to the design and are to be verified in the field by the engineer. If design changes are necessary, and the changes effect the contractor charges to the property owner, the contractor shall obtain approval from the property owner prior to proceeding with the work. 4. Once the dralarock is installed, the distribution pipe is to be placed level (0.02 feet difference between high and low shots) with the perforations faced downward. Drainrock is then to be placed over the distribution pipe, to provide a minimum of 2 inches of cover over the pipe. The dralnrock shall not be pyramided over the drainpipe but shall be the same elevation over the entire trench/bed width. 5. A silt barrier must be installed between the final drainrock layer and the native soil backfill. The silt barrier shall cover the entire drainrock surface. 6. Monitor tubes shall be installed at the locations shown on the design drawings, and extend a minimum of 12 inches above final grade. The portion of the monitoring tube extending through the drainrock shall be perforated from the bottom of the trench/bed to the invert of the distribution pipe. 7. Backfill over the final drainrock layer must not be less than 2 feet. Insulation must be installed when the backfill depth is less than 3 feet. The insulation shall cover the entire width of the trench/bed, the contractor shall "shoot" the final grades to ensure cover depth is adequate, prior to notifying the engineer that the work is complete. The final cover over the drninfield must graded so that there is no potential for water to pond over the trench/dralnfield. See "Contractor Responsibilities", paragraph 12 regarding final soil cover. 8. If an alternator valve was installed with this design the conlractor shah provide a functional valve key to[ the propert~ owner. I SECTION V: DISCLAIMERS UNFORESEEABLE SITE CONDITIONS: The design of this septic system, prepared by AKWWC, Inc., was based upon a limited evaluation of the soil, groundwater, and site conditions. The extent of the evaluation is consistent with standard engineering practice in the field. Furthermore, this design was evaluated and approved by the engineers or technicians on staff at the Municipality of Anchorage, DSD, based upon the information provided to them. Occasionally, during construction, unforeseeable subsurface conditions (high groundwater, poor soils, buried debris,....) are encountered that make the proposed installation not feasible. In such cases it is typically necessary to do more soils testing, groundwater monitoring, and design work. These additional engineering services will be performed on a fee basis at an hourly rate. AKWWC, Inc. will obtain verbal authorization fi.om the property owner (or his/her representative) prior to proceeding with the work, and will provide a written astimate if requested. The prope~ owner should discuss with the contractor any changes in the installation cost associated with the design changes. IF THE PROPERTY BEING SOLD AND FUNDS ESCROWED FOR THE UPGRADE, it is important to bear in mind that the ability to upgrade the septic system on this property is not 100% certain (for the reasons stated in the previous paragraph). There is always the possibility that conditions could be encountered that would prevent the installation of anything other than a holding tank. Although such a situation would be rare, it is important that all parties recognize that such a Page 6 of 7 AKIVWC Inc., lear 2002 scenario is possible. SEPTIC SYSTEM PERFORMANCE: The design of this septic system is based upon limited soils testing, groundwater monitoring, and a visual assessment. It is possible that the actual soil conditions are less favorable then the testing data indicated and that adverse, unforeseeable, changes in the surface/subsurface water conditions could impact the performance of the system. Numerous other factors, out of the control AKWWC, Inc., may adversely effect the long term performance of the system. Such factors include, but are not limited to. excessive number of residents in the house, plumbing leaks, the use of septic system additives, failure to pump septic tank regularly, failure to alternate drainfields (when this is an option), or/and excessive use of water. Given these variables, it is not possible to warrantee the performance ora septic system. By proceeding forward with this installation, the Engineer, Well Driller, Contractor, and Property Owner agree that they have read these specifications and agree to accept the terms and conditions outlined in them. NOTE: Additional charges for inspections will aool¥. A final invoice will be issued once all work is complete for inspections and documentation as required by the M.O.A. Please refer to the following estimated inspection costs: 1. Conventional septic system with a single trench/bed, no sand filter: $525.00 2. Conventional septic system with a single trench/bed, sand filter: $650.00 3. Conventional septic system, dual trenches, no sand filter: $775.00 4. Conventional septic system, dual trenches, sand filters: $950.00 5. Alternative Technolo~D' septic systems: $1000.00 6.
