Onsite Services Engineer: Th'e owner of Lot 9, Block 3, Skyhills Subdivision Phase I intends to construct a five bedroom home on the lot. We are therefore applying for a permit to construct a septic system on the lot to serve the new home. The attached Site Plan and backup documentation identify'the location and configuration of the new septic system and the parameters used in the design. It also shows the location of the water service on the lot. The subdivision is. served by the Municipal water system so conflicts with surrounding wells is not an issue, . · : Two test holes were placed on the lot in the area of the new absorption trench. Both holes revealed similar materials with well graded silty gravel with a percolation rate between 14 and 20 minutes per inch: No groundwater was encountered in either excavation and none accumulated dunng the monitoring period,. We have therefore designed a deep absorption trench system With 10' of gravel beneath the distribution p!pe. Th.e, total length of the trench will be 63'. The distribution pipe in the trench will be place 1.5 beneath the existing ground surface. Total depth of !he tren.ch, from odginal grade will be 11.5'. Fill will be placed over the trench to provlde'a minimum of 3' of cover. The ground surface on the lot slopes from west to east at steep grades from the road and flattens out to between 10% and 15% in the area of the new absorption trench. It also slopes from south to the north at varying grades. The new trench will be · constructed parallel to the contours of the surface in conformance with Municipal requirements. Grading will be accomplished to assure surface drainage is away from the new trench. ' If the system ii constructed in accordance with our design the following statements apply: ]. The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. The subdivision is currently served by the Municipal water system. Lot 9, Block 3,' Skyhills Subdivision August 25, 2000 Page Two The system, if construct(~d as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. . --The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. .. 'The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

Name of Firm: Garness Engineering Group, Ltd (GEG) Address: 3701 East Tudor Road, Suite 101- Anchorage, Alaska 99507 Engineer's Printed Name: Jeffrey A. Garness Phone: 907-337-6179 Date: I � 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 system/s; 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. Reliance upon the information provided in this report by any other person or party (including subsequent property purchasers) is not authorized, nor will it confer any legal right whatsoever. 6.
