The attached site plan and backup documentation identify the size and location of the new system to serve the house to be constructed on the lot. The subclivision is .served by a community water system and all required separation distances are easily met. Percolation tests completed on soils in the area of the new absorption trench and alternate site indicated a rate of 14 to 15 minutes per inch. We propose to place a 5' wide absorption trench with a total length of 57'. Four feet of drainfield rock will be placed beneath the distribution pipe. Total depth of the system will be 8'. No groundwater was found during excavation of the testholes and none was noted during the monitoring period. No surface water was noted in the area. ' The ground surface in the area of the new trench slopes at a rate of approximately 4% from north to south. This slope increases toward the south property line. If the. system .is constructed as designed 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 a community water system. 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. Lot 12, Block 3, Knik View Estates July ,1, 1997 Page Two The system, if constructed as designed, will 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.
