Box 196650 Anchorage, AK 99519 Re: Raven Woods Pl Lot 7, Block 4 Narrative & Pem~it Application Dear Mr. Cross: The proposed well and septic system will have very limited impact on adjacent properties for the following reasons: 1. The surrounding lots are large, allowing sufficient room for septic sites. 2. Immediate neighboring septic systems are all +30' distance. 3. Reserve space is adequate, due to absorption capacity. 4. Drainage will not be affected and is not a major consideration in our design. If you have any questions please call our office at 694-5195. Sincerely, Louis Butera, P.E. \1996\96-067A-NAR.DOC SPECIFICATIONS FOR ON-SITE SEPTIC SYSTEM LEGAL: Raven Woods #1 Lot 7, Block 4 08/02/96 GENERAL 1. The well and septic plan are for a single family residence only. 2. The drawing and or site plan shall be a part of this specification. 3. All materials and workmanship shall meet the Anchorage Department of Health requirements. 4. All soil tests are advisory to the design and are to be verified or modified in the field by the engineer. 5. All excavations and depths are advisory and are to be verified in the field by the contractor to meet Municipality of Anchorage requirements. 6. It is the responsibility of the owner to obtain all necessary permits or easements and to locate any adjacent multi-family wells. 7. The excavation is to be exactly in the area shown on the site plan, any deviation requires engineer approval. 8. It is always recommended that a surveyor locate the nearest lot line position and the location of any easements. 9. Any remaining open test hole excavations shall be filled. SEPTIC TANK 1. Septic tank shall be 1,000 gallons minimum, and MOA approved. TRENCH 1. The trench is to follow the natural land contour to maintain uniform total depth of the trench bottom. 2. The bottom of the trench shall be level, plus or minus 1.5". 3. The total depth of the trench excavation is not to exceed 13' at any point. 4. The sewer line is to replace the existing sewer line that leads to the existing pit. The effluent line within the trench shall be laid level within 0.03'. 5. The trench gravel is to be covered with typar fabric material. 6. Soil or combination of soil and extruded board insulation to a depth of 3' or equivalent is to be placed over the leachfield. 7. The area over the trench is to be finish graded to prevent ponding of surface water runoff. 8. The septic tank and leachfield must not be closer than 100' to any existing private well, 150' to any Class "C" well, or 200 feet to any community well.

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 Gamess Engineering Group, LTD. (GEG) Phone 907-337-6179 Engineer's Printed Name _ Jeffrey A. Garness Date In conducting this evaluation, GEG provided an engineering evaluation of the well and/or septic system in accordance with the guidelines and regulations established by the Municipality of Anchorage and industry practices. The reported results describe the condition of the system/s on the date/s of the evaluation. Separation distances were measured to readily identifiable features. Hidden defects or encroachments may exist that were not identified during the evaluation. The operational life of all wells and septic systems depend upon a variety of variables, including (but not limited to) soil conditions, groundwater levels (that may fluctuate during the year), quality of construction (materials and workmanship), and the water usage of the family utilizing the system/s. These conditions can vary, and are outside the control of GEG. Satisfactory test results do not guarantee future performance of the systems; therefore, GEG makes no warranty (express or implied) regarding the future performance of the well or septic system. GEG makes no representation whether an alternative well or septic system can be installed on the property in the event either of the current systems fail to perform adequately in the future. The content of this report is for the sole benefit of the person/party that retained GEG to perform the evaluation.
