Once the permits are approved, we propose to explore the <br /> subsurface conditions at the site by drilling one boxing to a depth of about 10 to 20 feet below the <br /> present ground surface or to groundwater,whichover is less. Per SICVM criteria,we will drill a <br /> test hole at each lot to a depth of about 3.5 feet below site grade for percolation testing. Based on <br /> previous experience in the LodMockeford area,we anticipare the soils at rhe site could consist of <br /> moderately perrucable silty sands. However, soils in the project area tend to be variable and <br /> could consist of clays or hard pan that will not meet tM county percolation criteria for onsite <br /> sewage disposal; in which case, a deeper perealating sail stratum (25 feet depth maximum), if <br /> present, would zteed to be located at each lot Once a potential do%= soil strartmt is <br /> cacomntered,we anticipate that we will need to drill one to two Additional test holes in each lot <br /> for percolation testing. If the near-surface soils exhibit adequate percolati m cbaracteristics, rhe <br /> deeper percolation rests will not be performed. <br /> After the percolation holes axe pre-soaked for a minimum 24 hour period, we will install a <br /> perforated pipe and about 2-inches of tlean gravel at the bottom of each An approximate&inch <br /> head of water will 1h m be placed over the gravel for percolation tudog. The water•level in the <br /> Lest boles will be measured at approaamalcly 30-minuto intervals for four hours, refillm as <br /> necessary to maintain the 6-incb bead of water.
