In addition, the absorption pit is seriously stressed and is also in need of replacement. We are therefore requesting a permit be issued to construct a new septic system as shown on the attached Site Plan to serve the 4 bedroom duplex on the lot. The Site Plan and backup documentation identify the location and configuration of the existing septic system and the location of the new tank and absorption system. Aisc identified on the plans is the existing well on the lot and those on the adjacent propedies. No conflicts exist between the existing well and the proposed septic system on this or the adjacent lots. The existing tank and the existing absorption pit on the lot will be properly disposed in accordance with Municipal Code. The test holes placed on the lot indicate silty gravel with some sand in the area of the new absorption system (GM/ML). The percolation rate was determined to be 4.2 minutes per inch in the zone designated for effluent absorption. Our proposed design includes the placement of a new 1,250 gallon septic tank along with a 50' long x 5' wide x 4' effective depth absorption trenches. The total depth of the trenches will be 8' with the distribution line placed at 4' below the surface. A-f. ..... r .................. ~, ..... to i ,~nsur, e e'v~, flow to each trc.~ch. A minimum of 4' of cover will be placed over the new tank and 3' over the absorption system. The ground surface on the lot is fairly flat with a minor slope to the southwest in the area of the septic tank and absorption trench. The trench~ will be constructed parallel to the contours of the ground surface as much as possible. ~ If the septic system is constructed in accordance with our design the following statements apply: The septic system, if constructed as designed, will have no adverse impact on T14N R2W Section 12 Lot 4 of BLM Lot 11 June 1, 2016 Page 2 of 2 the wells in the area or those to be constructed in the future. The septic 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 septic 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 septic 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.
