Park Estates Subdivision Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: The owner of Lot 1, Block 9, Mountain Park Estates Subdivision intends to construct a new five -bedroom home on the lot. We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. Also identified on the plans are the locations of the existing wells on adjacent lots in the subdivision. No conflicts exist between the proposed well and septic system and those on adjacent lots. Drainage arrows are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. Test holes placed in the area of the absorption trench and alternate site indicated silty sand with minor amounts of gravel. The percolation rate of this material was determined to be 8.5 minutes per inch in Test Hole No. 1 to 44 minutes per inch in Test Hole No. 2. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. We are proposing to place a new 1,500 - gallon septic tank and 2 - 60' long by 3' wide by 7' effective depth absorption trenches to treat and dispose the effluent generated in the house. The elevation of the distribution line in the absorption trenches will be 3' below the surface and the total depth will be 10'. A flow splitter valve will be placed to insure even flow to each trench. The trenches have been designed with an application rate of .45, which compensates for the slower percolation rate of the material in Test Hole No. 1. The majority of the absorption system falls within the 30' radius of Test Hole No. 2 however. A minimum of 3' of fill will be placed over the absorption trenches and 4' over the septic tank. The ground surface on the lot in the area of the septic system slopes at varying grades Lot 1, Block 9, Mtn. Park Estates June 22, 2005 Page Two from northeast to southwest. The new trench will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from the existing wells and any surface water in the area. If the system is constructed in accordance with our design the following statements apply: 1. 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. 2. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. 3. 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. 4. 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, 74'-<�L E 04-- -, Michael E.

Name of Firm: Garness Engineering Group Ltd (GEG) Phone: 907-337-6179 Address: 3701 East Tudor Road Suite 101- Anchorage Alaska 99507 f 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 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.

Engineer's Comments: In conducting this evaluation, GEG, LtD, attempted to provide a thorough, conscientious engineering analysis of the system in accordance with ADEC and MOA DSD Guidelines 8 Regulations. The reported results described the performance of the system under the conditions encountered at the time of the fest, 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 DSO.
