It has failed and must be replaced. We are therefore requesting a permit be issued for the upgrade of the septic system to accommodate the four- bedroom duplex on the lot. The attached Site Plan and backup documentation identify the location and configuration of the existing and proposed septic systems. The existing septic crib will be decommissioned in accordance with Municipal Code and a new 1,250 Gallon Septic Tank placed at the location shown. A new absorption trench will be constructed in accordance with Municipal Code. Also identified on the plans are the locations of the existing well on this and adjacent lots and adjacent septic systems. No conflicts exist between the proposed septic system and the wells on this or adjacent lots. Protective radii are shown to the adjacent wells. Drainage arrows are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. The test hole placed on the lot indicated Well Graded Gravel with Sand and Silt (GM/SM) the entire depth. The percolation rate was determined to be less than 5 minutes per inch. We have designed the new trench with an application rate of 1.2 gallons per date per square foot. No groundwater was found in the test hole and none developed during the monitoring period. We are proposing to place a 50' long trench by 5' wide with a 4' effective depth. The total depth of the system will be 8' with the distribution line at 4' below the existing surface. The ground surface on the lot is virtually fiat in the area of the proposed absorption trench. The trench will be placed parallel to the contours of the ground as much as Lot 8A, Block 3, Seacliff September 11, 2012 Page Two possible and in conformance with design criteria. A minimum of 100' will be maintained between all components of the septic system and the existing well and 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.
