CONCLUSIONS <br /> Although the shallow depth percolation test results indicate no percolation even after opening <br /> smeared sidewall surfaces of the test boring, soil permeability will still occur due to the nature of <br /> the teeth of the backhoe bucket opening the soil during leachline installation. Eventually, due to <br /> biomat buildup and the sealing of the leachline trenches,the three, 36" dia. seepage pits will <br /> manage most of the effluent flow volumes. Ample area exists on the subject property for a 100% <br /> replacement area. <br /> Taking an average of the acceptance rates obtained,the OWTS to be installed can manage: <br /> 0.524 gals/ftz/day x 1,068 ft' (infiltration area of the 3 leachlines and 3 pits)= 560 gpd. <br /> In 1999,the depth to groundwater was measured at 90 ft bgs. This can be considered the highest <br /> depth to groundwater. In the Fall of 2016,the depth to groundwater was measured at <br /> approximately 130 ft bgs. <br /> Respectfully submitted, '?T fess'. <br /> CHESNEY CONSULTING a e °" <br /> or cher"a <br /> I o <br /> 40 . <br /> No.75479CD <br /> CD <br /> tr <br /> Don Chesney,PE fd�e civil ,�� <br /> Registered Civil Enginee #C75479 °f catij°` <br /> ATTACHMENTS <br /> APN and District Viewer Maps Denoting Project Location <br /> EHD Percolation Test Rate Forms with Test Locations and Field Data <br /> Groundwater Maps <br /> Page 3 of 3 <br /> Chesney ConsultinJ <br />
