The attached site plan identifies the location of the home, well, and existing septic bed. No conflicts exist between this proposed system and any other well or septic system, whether on this lot or adjacent lots. The ground surface on the lot slopes in general away from the road toward the northwest, but there is a flat area in the front where the existing bed is located. The slopes are less than 10%, and there are no slopes greater than 25% within 50 feet downslope. Contours are shown on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. Wells on this and adjacent lots are shown. The new system will be a minimum of 50’ from all wells and surface water, and more than 5’ away from the septic tank. There is a curtain drain right along the property line to Audubon Drive, and the new bed will be located a minimum of 10’ from that. Please refer to the attached test hole logs, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

Box 196650, Anchorage, AK 99519-6650 (907)343-7904 Ref: Proposed Well and Septic System for Audubon Hills Subdivision; Lot 4, Block 1, To whom it may concern: The proposed 4 bedroom house will be served by a private well and septic system. The well is to be drilled in the area shown on the attached site plan. A total of 6 test holes have been excavated on the property. Due to high groundwater readings in the test holes and saturated soils in the area, we proposed to install a curtain drain. A curtain drain was installed along the southeast property line and became operational on 1/27/2005. We are proposing to design a drainfield around the 30 foot radius of test hole #6. Prior to the installations of the curtain drain, groundwater was found in TF1#6 at 3.67 feet below ground surface (BGS) on 12/29/2004. After the installation of the curtain drain, groundwater was found to be at 5.5 feet BGS on 2/3/2005. It appears that the curtain drain has lowered the groundwater level in this test hole by 1.83 feet. Based upon this groundwater reading, there is currently over 4 feet of suitable, unsaturated, receiving soils. We are proposing to install a new 1500 gallon Advantex Treatment System with pump vault and a mounded bed type drainfield. We are proposing to install the bed with a 6 foot separation from the the bottom of the drainfield to the current groundwater level reading and impermeable soils. We anticipate that the new curtain drain will continue to cause the groundwater to subside. Comments regarding the design are summarized as follows: 1. SOILS: See the attached logs which shows the soil classifications, groundwater monitoring, and the percolation test results. 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications. 3. SURFACE WATERS: There is a curtain drain that runs along the southeast lot line and outfalls near the northwest comer of the lot. The proposed drainfield is to be installed over 20+ feet downhill from the curtain drain and over 100 feet the outfall of the curtain drain. 4. TOPOGRAPHY: As can be seen on the attached design drawing the average topography around the drainfield is a 10± percent slope running approximately southeast to northwest. Directly below the drainfield the slope decrease to a 5-10 percent slope and than gradually becomes generally flat. 3701 E.

Owner agrees that any sale or transfer of title of the property will not occur without a new Certificate of On -Site Systems Approval. '� Owner agrees that the AWWTS installation and maintenance requirements as provided by the AWWTS vendor/installer and approved by the Municipality are the governing guidelines for the construction, maintenance and repair of the Owner's AWWTS. Owner agrees to maintain remote monitoring of the AWWTS as required by the AWWTS approval. 3. Term. The term of this Agreement shall begin on the date of approval by the Municipality to operate the installed system, or upon transfer of title, and shall continue while the AWWTS is operational or until title is transferred. 4. Nonwaiver. The failure of the Municipality at any time to enforce a provision of this Agreement shall in no way constitute a waiver of the provisions, nor in any way affect the validity of the Agreement or any part hereof, or the right of the Municipality thereafter to enforce every provision hereof. 5. Amendment. This Agreement shall only be amended by authorized representatives of the Owner and Municipality. Any attempt to amend this agreement by either an unauthorized representative or unauthorized means shall be void. 6. Jurisdiction: Choice of Law. Any civil action arising from this Agreement shall be brought in the Superior Court for the Third Judicial District of the State of Alaska at Anchorage. The laws of the State of Alaska shall govern the rights and obligations of the parties under this Agreement. 7. Severability. Any provisions of this Agreement decreed invalid by a court of competent jurisdiction shall not invalidate the remaining provisions of the Agreement.

Date _01710f, Engineer's Comments: In conducting this evaluation, GEG, UD. attempted to provide a thorough, conscientious engineering analysis of the system in accordance with ADEC and MOA DSD Guidelines & Regulations. The reported results described 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 soils condition, groundwater 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 the system. Satisfactory test results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments. GEG, LTD. can therefore not provide any warranty or future estimate of how long the system will continue to meet the operational requirements of the ADEC or MOA DSD. The content of this report Is for the sole bonefit of the owner listed above. Any reliance upon or use of this report by any other person or party Is not authorized, nor will it confor any legal right whatsoever. 5. DSD SIGNATURE V Approved for _q bedrooms. Disapproved.
