The acceptance rate for the onsite native soils under saturated soil conditions can be considered to i <br /> be 0.1 gallons/ft2/day. 200 gpd ADF_ 0.1 gallons/ft2/day=2,000 ft2. <br /> ADU Filter Bed Disposal area to be installed= 30 ft N-S x 70 ft E-W=2,100 ft2. One seepage pit <br /> infiltration area is 264 sf=2,364 sf total infiltration area. Reserve/replacement.area=2,296 sf. <br /> A Well Completion Report(well log) from a domestic well 1400 ft to the east from the subject <br /> property indicates a coarse sand stratum from 15 to 20 ft in depth, as illustrated in Appendix E. <br /> This data was used in lieu of conducting a 25 ft deep perc test. <br /> LIMITATIONS <br /> The findings, opinions, calculations and conclusions of this report are based upon information from <br /> standard engineering and analytical test procedures, contemporary scientific literature and agency <br /> consultations. Information used in these studies is deemed reliable by the sources from where it <br /> was obtained. <br /> This report is based upon current scientific knowledge to assess factors which are extremely <br /> variable and complex within the environment.
