No groundwater was found during the excavation and none has been noted to date. We will continue to monitor the water level during the construction of the new system. The total depth of the new system centered around Testhole No. 1 was raised 1' to compensate for the rise in the groundwater to the 13' level noted during your site visit. The bottom of the trench will have the necessary 4' clearance from groundwater. W'",~-~.;~0 ~,u- t,~ We again checked the percolation rate in Testhole No. 2. The percolation test shown on the soils log is accurate. The accumulated water in the percolation cavity is probably caused by siltation around the edges of the cavity. We are confident the soil will percolate at the rate indicated. All items mentioned during your site visit have now been addressed. We are hOpeful the septic system permit for this lot can now be issued.

Health & Human Servioe,,I Lot 22, Block 3, Knik View Estates Subdivision Septic System Design Impacts to Adjacent Properties Dear On Site Services Engineer: We hereby apply for a permit to construct an onsite septic system on Lot 22, Block 3, Knik View Estates Subdivision. The attached site plan and backup documentation identify the size and location of the new system to serve to be constructed on the lot. 1-he subdivision s served by community water and all required separation distances are easily met No conflicts exist with other septic systems in the area. Testholes performed on the property revealed silty gravels which percolated between 30 and 60 minutes per inch. This material is overlain by a layer of poorly graded gravel which percolates much faster. We have designed the absorption trenches, however, to be primarily in the slower percolating rnaterial. Total depth of the system will be 10' below the surface. Insulation may be required to prevent frost penetrati°n into the absorption trenches. The surface of the lot slopes from southeast to northwest at grades varying from 3% to 5%. The surface of the ground in the area of the absorption trenches is fairly flat. The lot is of sufficient s~ze so that no encroachments will exist between the septic system and any future systems in the area. Property to the southwest is currently vacant . if the system is constructed as designed the following statements can be made: 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 a community water system Lot 22, Block 3, Knik View Estates Subdivision May 22 1997 Page Two 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 The system, if constructed as designed wil have no adverse impact on reserved space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse ~mpact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

These inspections must be conducted under the supervision of a professional engineer registered in the State of Alaska. The first inspection must be conducted after the excavation of trenches, beds or pits and before the installation of any gravel. A septic tank may be set in place, but rnay not be backfilled. The second inspection must be conducted after the placement of the geotextile fabric, gravel, distribution i piping, standpipes, cleanouts and insulation. No backfill should be in place at the time of inspection. Contractor shall provide acopy of all field survey layout and construction notes for use in preparing the certified as-built of the completed system.
