Due to site constraints, we propose to remove and replace the existing trench to serve the existing 3-bedroom residence. The location of the existing system to excessive slopes has not shown any or known to have any daylighting issues since installed 19 years ago. Based on this information, the soils present and observations of the field it appears that the field will become saturated prior to any possibility of horizontal / downslope daylighting. The design is based on the test hole conducted previously for the exiting system. The lot and area is served by private water and the design will not impact any of the neighboring properties. Please contact Brent M. Western or me if you have any questions. Sincerely, Michael N. Anderson, P.E.

Waiver Fees: Receipt # 72-012 (Rev. 4/98)* Waiver # ALASKA WATER & WASTEWATER March 30, 2000 Municipality of Anchorage Department of Health & Human Services Division of Environmental Services On-Site Services Section P.O. Box 196650 Anchorage, Alaska 99519-6650 Reft Well and Septic Design for Lot 8, Undermountain Estates Subdivision To whom it may concern: The proposed 3 bedroom house will be served by a private well and septic system. Test holes were excavated on the property. The proposed septic system will be designed around the 30 foot radii of test hole #1 and #2. We are proposing that a 1000 gallon septic tank and a five foot wide drainfield be installed. Comments regarding the proposed design are summarized as follows: 1. SOILS: Attached are logs which shows the soil classifications, groundwater monitoring, and the percolation test results. In both test holes, the soils below the organic layers are a GIWSM/ML material to a depth of 13 feet in TH#1 and to a depth of 14 feet in TH#2 (bottom of test holes). Fractured bedrock was encountered was encountered at the bottom of both test holes. No groundwater was encountered during the excavation of the test holes. A percolation tests were performed in both test holes between the depth of 4.5 feet to 5.0 feet which had percolation rates of 13.3 (TH#l) and 12.0 (TH#2) minute/inch. It is our opinion that due to the overall appearance of the soils, a application rate of 0.8 gallons/day/ft2 should be used. 2. TRENCH DESIGN: a. Percolation Rate: 13.3 & 12.0 minutes/inch b. Allowable Application Rate: 0.8 gallons/day/f~2 c. Number of Bedrooms: 3 d. Design Flow: 450 gallons per day e. Minimum Absorption Area: 563 ft2 f. Total Depth: 7 feet (Maximum) g. Effective Depth: 2.5 feet h. Width: 5 feet i. Reduction Factor: 0.64 i. Minimum Length: 75 feet long j Effective absorption area = 586 ft2 6901 Debarr Road, Suite 2B - Anchorage, AK 99504 - Pr: (907)337-6179 ~ Fax: (907)338-3246 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed septic area. 4. TOPOGRAPHY: As can be seen on the attached design, the slope runs approximately from northeast to southwest. The test holes were excavated in area were the slopes ranged from 25 to 30 percent,. The slopes uphill from the test holes are greater than 30 percent and the slope gradually increases downhill from the test holes to where the slope is also greater than 30 percent. According to the developer, O'Reinedeer Road is scheduled for road improvements in the spring/summer of 2000 where a large amount of excavated material from the road will be used as fill below the proposed septic system area in order to insure there are no slope greater than 25 percent. The trench will be installed parallel to slope contours. 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 assistancej// NOTE: Attached is a site plan drawing, a design drawing, two soils logs, and a 7 page construction specification letter which are all part of the design package for this septic system. 6901 Debarr Road, Suite 2B - Anchorage, AK 99504 - Ph: (907)337-6179 ~ Fax: (907)338-3246 SW END OF LOT / ................. ~ ..............

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 Arcterra Consulting Phone (907)-696-6111 Engineer's Printed Name Kenneth Duffus Date Engineer's Comments: This investigation was completed in compliance with ADEC and MOA regulations. 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 inland use, local soil characteristics, groundwater levels that may fluctuate during the year and the water usage of the family being served by the system. 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, ArcTerra can not give any estimate of how long a system will function satisfactory for current or future occupants or can ArcTerra guarantee that no unseen encroachments, deficiencies or discrepancies exist.

Box 196650 Anchorage, Alaska 99519-6650 Reft Lot Line Waiver for Lot 8, Undermountain Estates Subdivision To whom it may concern: We request that your department issue a 5 foot lot line waiver from the east property line to the new drainfield. During the inspections there was some surveyors flagging that was marking the east lot line. The new drainfield was measured from this flagging and found it to be 10 feet a~vay. A as-built survey has been performed (see attached) and it appears the new drainfield is 5+ feet from the lot line. We are unaware of any adverse effects this would have on the adjacent propm~y. assistance. Presi~n~ If you have any questions, please contact us at 337-6179. m~, P.E., M.S.
