September 9, 2024 Municipalities of Anchorage On-Site Water & Wastewater Program 4700 Elmore Road Anchorage, AK 99507 RE: SEPTIC SYSTEM UPGRADE PERMIT LEGAL: THE TABLELANDS BLOCK 4, LOT 23 The property owner has requested we obtain a permit to upgrade the failed septic absorption field of the above referenced lot. Due to site constraints, we propose remove and replace the existing field to install an identical trench as previously existing. The septic tank integrity will be inspected at installation. Municipality of Anchorage (MOA) existing record documents show a 50’ separation to the top of the slope. However as shown on the design, approximately 21’+ at the closest part of the field appears to be the separation. There was no effluent daylighting with this typical existing saturated field failing upwards with no effluent surface observance and appears that there has been or will be no adverse effect upon public health and safety with the continuance of the slope proximity. This proposed remove & replace septic upgrade is at or below the top of the grade that slopes towards the driveway and away from the top of slope as shown on the design. The top of slope downwards is heavily vegetated with brush, alders, mature tall trees and no private property below with no possible effluent daylighting or observed. The remainder of the slopes are basically flat and moderate at 0-5% at the proposed upgrade location. The design is based on the original test hole information obtained from the MOA record documents. No groundwater was observed at test hole excavation or monitoring. The lot and area are served by public water. The design will not impact any of the neighboring properties. Please contact us if you have any questions. Sincerely, Curtis Huffman, P.E.

They are high in elevation and very well drained. This is made possible by a fortunate geologic formation. The two lots he along the crest of a ridge with topography dropping off to either side. This is a drumlin glacial feature or has similar characteristics to a drumlin. Because of this, the soil is dry at depth and no groundwater was present after monitoring. The soil also exhibited superior percolation during testing. For these reasons, conventional septic systems should function well for wastewater treatment. Please review the new septic system designs for the planned 4 -bedroom single family homes. I have included design plans & specs, design guidelines, & soil tests. If there is need for additional information or clarification please give me a call. Sincerely, eve Eng, PE, P Design Enclosures WEERI� N�G�— J The Tablelands S/D, Lot 23, Block 4 SPECIFICATIONS & DESIGN GUIDELINES Wastewater System Sizing: This is a single family home projected at 4 bedrooms. This requires a 1250 gallon septic tank. The is a large lot- 56,623 FT2. Lot 22 to the north is also large at around an acre in size. Lot 22 is the only neighboring lot. A greenbelt is situated to the west and Oberg Road to the east. This lot sits along a ridge- see sheet 2 for drainage features. For this reason the lot is well drained and no groundwater is present. No adverse impacts are expected from developing this lot. The lots are served by a public water system. No conflicts to any neighbor lot is anticipated. This lot exhibited superior soil with an good percolation rate; a silty sandy gravel. An application rate of 1.2 GPD/FT2 with 0.5 reduction factor for utilizing a 5' wide trench is utilized. Monitoring revealed no groundwater on this well drained lot. Specification Requirements: All components and work must comply with the Municipality of Anchorage Specifications (AMC) & State of Alaska Drinking Water Regulations and Wastewater Regulations. • Two compartment septic tank • Watertight couplings on inlet & outlet • 5 foot minimum between the tank and bed. 10 foot to property lines. • 3 feet of cover or insulation is required for trench; an equivalent of 1" insulation for each foot soil cover. • Tank & solid pipe must be set on well compacted, stable soil • 4 inch diameter cleanouts with airtight caps are required 1 to 4 feet from foundation wall, prior to any 90 degree bend in 4 inch line, in each tank compartment, and two adjacent opposing cleanouts between the tank and the absorption field, not more than 10 feet from the tank positioned to provide cleanout access towards the tank and towards the absorption field. • All cleanouts must extend to at least ground level • In solid pipe runs, ASTM D-3034 may be used in lieu of cast iron • Trench to be placed level, minimum of 4 feet to groundwater, 6 feet to bedrock from drain -rock • Drain rock to be'/2 inch to 2'/2 inch screened. Drain rock to be distributed uniformly throughout the trench. • Perforated pipe to be installed level with perforations down • Silt barrier (filter fabric) to be installed above the drain rock • Smeared trench sides must be raked or scarified before drain rock placement • Backfill over drain rock must not be less than 36" • The finish grade must be mounded to promote drainage over the bed • Insulation must be placed over any pipe installed under driveways or parking areas • Approved pipe materials include cast iron, PVC ASTM D3034, PVC ASTM F789, ABS ASTM D2661, • Sca er Service Linc is minimum 2% slope • Septic Tank to be pumped every two years or when required 0 Insulation board to be extruded direct burial polystyrene (Dow Styrofoam IU or equal) 0 a 0 n: c� o: w 0 0 Reserve Site \ Absorption i T Keybox a —Jo-- 3 T.H.2 �\ o C.O.'s Galion Septic Tank F.C.O.

ENGINEER’S COMMENTS G. CERTIFICATION & 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, indicates that the on-site water supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation, unless noted otherwise. Name of Firm FIRST WATER CONSULTING Phone 907-350-9566 Engineer’s Printed Name CURTIS HUFFMAN, PE Date 11/04/2024 Comments: This investigation was completed in compliance with MOA guidelines, regulations, and best industry practices / methods. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & 11/04/24 i TRACT B-2 ASPLS MORTGAGE LOCATION SURVEY NOTES: NO TITLE REPORT WAS PERFORMED FOR THIS SURVEY, EASEMENTS SHOWN PER THE RECORD PLAT.
