Box 196650, Anchorage, Ak 99519-6650 (907) 343-7904 Ref: Redesign of Proposed Septic System for Lot 4, Block 6; Tablelands Subdivision To whom it may concern: A sewer permit was issued for the referenced property on April 27,2004 by your department. The permit has expired and the contractor has requested for us to have the permit reissued. The original design was for a dual 5 -wide type drainfield system. During the installation of the adjacent septic system (lot 5), we found groundwater to be at 6.5 feet below ground level for the two test holes on this property. We have redesigned the proposed septic system to use a bed type drainfield. The proposed 3 bedroom house is to be served by public water. Comments regarding the design revisions are as follows: 1. SOILS: Attached are two soil logs which shows the soil classifications, groundwater monitoring, and the percolation test results. We are proposing to design the septic system around test hole 49 which had a percolation rate of 30 minute/inch. The proposed drainfield does encroach upon test hole #8 which had a percolation rate of 60 minutelinch. We are proposing to use a combined application rate of 0.35 for the proposed bed drainfield. Also, due to the fact that the proposed drainfield is not encompassed by the test hole radii, we are proposing to perform a confirmation percolation test prior to the installation in the area shown on the design drawing. 2. TRENCH DESIGN: a. Percolation Rate: 30 & 60 minuteslinch b. Allowable Application Rate: 0.35 gallons/day/ft2 c. Design Flow: 450 gallons per day d. Minimum Absorption Area: 1286 ft2 e. Total Depth: 2.5 feet (max.) f. M.O.A. Appproved Sand Filter: 1+ feet g. Effective Depth: 0.5 feet h. Width: 15 feet i. Minimum Length: 86 feet long j. Effective absorption area = 1290 ft2 3701 E. Tudor Road, Suite 101 • Anchorage, AK 99507 Ph: (907) 337-6179' Fax: (907) 338-3246 • Website: gamessengineering.com 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed upgrade. 4. TOPOGRAPHY: As can be seen on the attached design, the proposed drainfield is to be installed on a 1 to 5 percent slope running approximately southeast to northwest. In short, there are no slope concerns. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact me at 337-6179, or 244-9612. Thank you for your assistance. P.E., M.S. 3701 E.

RESPONSIBILITIES: a Property Owner Responsibilities: 1. CONTRACTUAL RELATIONSHIP: The property owner shall contract 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, Department of Environmental Conservation. 3. DISCLAIMER REGARDING AS -BUILT SURVEY: The validity of the design site plan is limited by the accuracy of the as -built survey provided to the engineer by the property owner or his/her representative. The property owner shall notify the engineer regarding any known inaccuracies associated 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 contractor of any unplatted easements, not shown on the as -built survey, which the new well or septic system may encroach into. Such easements are typically identified in the property title report. S. DISCLOSURE OF SITE CONDITIONS: The property owner shall notify the engineer and the contractor 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 Page 1 of 7 CEG, Ltd., Year 2004 disclosure is of particular 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. 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 multifamily dwelling. The new septic tank and 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 includes 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 after construction. Prior to awarding the contract, the homeowner should communicate to the contractor any expectations regarding, but not limited to post construction site clean up, re -landscaping, and restoration of any asphalt, fences, trees, 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 after 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 he/she 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 and 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 any questions by the property owner, or his/her representative, regarding charges for installation inspections they should be discussed prior to beginning construction. GEG, Ltd. 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 Responsibilities", 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 lines 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 means, prior to construction. GEG, Ltd. field engineers/inspectors will not be responsible for establishing or confirming any of the aforementioned setbacks. contractor should recognize that the location o[ all wells, sur[ace waters, structures, ana ower m m on the design drawings are typically derived from as -built surveys, and municipal records. The surveys and municipal records (prepared by professional engineers & land surveyors) have b tined to be accurate for purposes of this design; however, the accuracy has pot necessarily been f Page 2 of 7 GEG, Ltd., Year 1004 Prior to beginning any construction the contractor shall field locate all items which h le setbacks and verify that there are no encroachment concerns. Any encroachments, for wt have not been granted, should immediately be brought to the attention of the property owner resentative) and the eneineer. 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 installation or during the pre - construction layout. The new drainfield/s must be 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 be maintained. This is particularly significant when the elevation of the existing system components is unknown because clean -outs are not present, buried, or non-functional (can't measure down them because of obstructions). It is recognized that conditions can be discovered that will materially change the design and the construction Boss. 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 be 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 takin measurement at the deepest part of the excavation between the highest ground elevation encounu (usually on the uphill side of the excavation) and the bottom of the trench or bed excavation. contractor shall exercise caution not to remove evidence of the original grade prior to establishment of total system depth In short, don't remove the organic layer until after the original grade elevations 5. SUITABILITY OF MATERIALS USED FOR CONSTRUCTION. The contractor shall ensure that Ll materials being used are in compliance with the most current guidelines established by the Municipality of Anchorage. This includes, but is not limited to, the following: a. Draimock b. Sand filter material for conventional beds, trenches, or mound systems. c. Sand filter material and pea gravel for Intermittent Sand Filters (ISF). d. Anchorage Sand and Gravel (AS&G) "block pea" material for Upftow Filters. It is recommended that the contractor provide the engineer with current sieve analysis' from the sand/gravel supplier to document the suitability of the material. The engineer assumes no responsibility for ensuring that the materials delivered meet the MOA requirements. 6. BURIAL RATING OF TANKS: The contractor shall ensure that the septic tank, lift station, or holding tank purchased has a burial depth rating suitable for the actual installation. 7. SEPTIC TANK AND STEP TANK SIZES: Prior to purchasing a septic tank or lift station the contractor shall verify that it is adequately sized for the number of bedrooms shown on the permit issued by MOA. The minimum septic tank size is 1000 gallons and the minimum STEP tank size is 1250 gallons. These size tanks will handle residences with up to 3 bedrooms. For each additional bedroom over three (3) the septic tank or the STEP tank volume shall be increased by a minimum of 250 gallons. For example, a four (4) bedroom residence must have a 1250 gallon septic tank or a 1500 gallon STEP tank. Page 3 of 7 GEC, Ltd., Year 1004 8. INSPECTIONS - ENGINEER NOTIFICATION: The contractor shall notify the engineer at least 24 hours prior to starting construction. If deemed necessary, a pre -construction site visit shall take place. The contractor shall coordinate with the engineer any inspections which will be required during weekends, holidays, or before/after normal working hours (8:00 am to 5:00 PM). The property owner may incur additional charges for inspections, which do not occur during normal business hours. It is the contractor's responsibility to notify the engineer a least 2 hours prior to any inspection. 9. REGULATORY NON-COMPLIANCE. The contractor shall report to the engineer and the property owner any observed condition which would put the septic system in violation of State or Municipal regulations. 10. BACKFILL OLD TEST HOLES: Any remaining test hole excavations shall be tilled and mounded as part of this project. Unless instructed otherwise by the engineer, the old test hole groundwater monitoring pipes shall be removed. 11. FINAL GRADING FOR DRAINAGE: The contractor is responsible for final grading so as to ensure that surface runoff does not adversely effect the septic system constructed, adjacent septic systems, or adjacent structures. 12. SOIL COVER REQUIREMENTS: The contractor shall ensure that the final cover over the tank and drainfield is either compacted adequately when backfilling, or mounded sufficiently to ensure that there is adequate soil cover over the tank and drainfield after settlement occurs. If seasonal conditions prevent this, the property owner (or his representative) shall be notified that additional fill may be required after settlement occurs. This notification is of extra significance when the property is changing ownership. 13. CHANGES IN CONSTRUCTION COSTS: The contractor is responsible for obtaining approval from the property owner for any additional construction costs associated with design modifications or changing field conditions prior to doing the work. 14. WORKING IN RIGlIT-OF-WAYS AND TRESPASSING PRIVATE PROPERTY: The contractor is responsible for coordinating (including payment of encroachment permit fees) all access through public and private properties with the appropriate authorities and/or property owners. Furthermore, the contractor shall inform all parties of any potential impacts to adjacent properties prior to beginning any construction. 15. MAINTENANCE & OPERATIONS MANUALS: The contractor shall provide the homeowner with the manufacturer's installation/maintenance manuals for all system components installed under this contract. If not given directly to the property owner, the manuals should be enclosed in a protective cover (plastic bag) and placed/secured in a prominent location so the property owner can find it. 16. 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 Advantex 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. The 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 to establish the following: • The original grades at the drainfield/s site • The bottom of all trench/bed excavation • Top of sand on all sand filters • Top of drainpipe Page 4 of 7 GEC, Ltd., Year 2004 • Septic tank, or lift station, or holding tank prior to backfill • Placement of filter fabric and insulation • After final grading is completed 2. 1,11MITED AUTHORITY: The inspecting engineer has no direct authority over the contractors activities or construction/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. S. 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 GEG, Ltd. ♦aaaaaaaaaaaaaaaaraa:a+:++::++++++araaaa:a:a+aaaaaaaaaraaaaaa♦++++a:aaa+a+►:+:a:a+• SECTIONIV. CONSTRUCTION GUIDELINES: 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 inspecting engineer to notice a material or construction non-compliance does not relieve the contractor of his/her responsibility to correct such a deficiency, • Septic Tank, Bolding Tank, or Lift Station Installation: 1. The burial rating of the tank shall be adequate for the actual burial depth encountered. 2. The tank shall be level and sufficiently bedded to prevent settling or shifting 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 shall be bedded in drainrock or the soil shall be adequately compacted to prevent future settlement of the soil. 7. A foundation clean out will be installed (1-4 feet from the house) if one 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 lift stations shall have an audible and visible alarm inside the residence. 12. All lift stations shall be wired in compliance with all MOA guidelines and the Uniform Electrical Code. A municipal electrical 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. Page 5 of 7 GEG, Ltd., Year 1004 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 remote 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 drainrock is installed, the distribution pipe is to be placed level (0.02 feet difference between high and low shots) with the perforations faced downward. Draimock is then to be placed over the distribution pipe, to provide a minimum of 2 inches of cover over the pipe. The drainrock shall not be pyramided over the drainpipe but shall be the same elevation over the entire trenchlbed 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 drainfield must graded so that there is no potential for water to pond over the trench/drainfteld. See "Contractor Responsibilities", paragraph 12 regarding final soil cover. S. If an alternator valve was installed with this design the contractor shall provide a functional valve key to the property owner. SF.CTIONV.- DISCLALVERS UNFORESEEABLE SITE CONDITIONS: The design of this septic system, prepared by GEG, Ltd., 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. GEG, Ltd. will obtain verbal authorization from the property owner (or his/her representative) prior to proceeding with the work, and will provide a written estimate if requested. The property 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 Page 6 of 7 CEG, Ltd., Year 1004 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 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 GEG, Ltd., 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 drainGclds (when this is an option), or/and excessive use of water. Given these variables, it is not possible to warrantee the performance of a 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. onal cha 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 trenchibed, no sand filter: $700.00 2.

STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined in the Certificate of On-Site Systems Approval Guidelines for this application, shows that the on-site water supply and/or wastewater disposal system is (are) safe,`functional and adequate for the number of bedrooms and type of structure indicated herein. I further verify that based on the information obtained from the Municipality of Anchorage files and from my investigation and inspection, the on-site water supply and/or wastewater disposal system is(are) in compliance with all applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation. In conducting an adequacy test, I attempt to provide a thorough,conscientious engineering analysis of the system in accordance with MoA COSA guidelines and regulations.The reported results describe the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil condition,ground water levels that may fluctuate during the year,and the water usage of the family being served by the system.These conditions are outside the control of the evaluator of this system. All systems eventually fail and satisfactory test results do not guarantee future performance of the system,nor do they guarantee that there are no hidden defects or encroachments.Therefore we cannot provide any warranty for future performance, nor can we estimate remaining life of the system.
