We are therefore requesting a permit be issued for the construction of a new septic system to serve the new home. The subdivision is currently served by a community water system. No conflicts exist with adjacent septic systems or wells and the proposed septic system on this lot. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system and alternate site. The current drainage pattern is identified on the Site Plan. The drainage pattern will be maintained after development of this lot is complete. Test holes recently placed on the lot indicated silty sand with minor amounts of gravel in the area of the absorption trench and alternate site. The accepting soils were tested and found to have a percolation rate of 6-13 minutes per inch. The system is designed with an application rate of .8 GPD/SF. No groundwater was found in the test holes during placement and none was monitored during the ensuing period. Our design, however, is based on the bottom of the trench at 5' below the surface and includes the placement of a new 1,250-gallon septic tank along with 2 - 38' long by 5' wide by 4' effective depth absorption trenches to collect and treat the sewage generated in the house. The distribution pipe will be 1' below the surface. A minimum of 3' of cover will be placed atop the trench and a minimum of 4' of cover will be placed atop the new septic tank. A flow splitter valve will be placed to assure even flow to each trench. The ground surface on the lot slopes at varying grades from south to north and north to south with a break near the center of the lot as shown on the Site Plan. The absorption trenches will be constructed parallel with the slope of the ground surface as much as Lot 2A, Block 4, The Tablelands Subdivision September 5, 2005 Page Two possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 10' from the water service proposed for the lot and on adjacent lots. It will also be constructed a minimum of 100' from any surface water in the area. If the system is 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 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. 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.

BOX 240773 ANCHORAGE, AK 99524 622-7773 677-7766 (FAX) MEMORANDUM DATE: September 14, 2005 TO: Julie Makela, P.E. FROM: Mike Anderson, P.E. SUBJECT: Lot 2A, Block 4, The Tablelands Subdivision Septic System Construction Permit Due to a computer transcription error the wrong information concerning ground water monitoring was included on the test hole logs submitted with the original permit application. The correct information has been included on the attached logs. We have also included the actual field information to verify the ground water monitoring. No groundwater was noted during the construction of the test holes and none was found during the monitoring period. The lot slopes steeply toward the back relieving much of the static pressure buildup and allowing the free flow of groundwater. We have designed the absorption trenches for this property to be a maximum of 5' below the surface. Test holes were placed to depths of 15' and remained free of groundwater to the present day even with the recent heavy reins.
