FrTheinal rate for Building A-S was 125 min/in. As noted on the Soil Analysis Report,the soilre at test depth for Building A-S is a clay(USCS =lean clay CL) with 50% clay and 18% <br /> sand fractions,while soil at test depth for Building B-S is a clay loam(USCS =silty clay CL-ML) <br /> with 35% clay and 27% sand fractions. <br /> These differences in soil texture at perc test depth(a lower clay content and higher sand content <br /> for Building B-S)may be a contributing factor as to why there is a significant difference (3x) in <br /> perc rates between these two locations. In addition, it may be that some type of activity in the past <br /> occurred in this A-S locale that created soil compaction characteristics,thus slowing permeability, <br /> since it is adjacent to the Holly Commerce Center facility entrance and Holly Drive. As noted <br /> below,the perc rates become significantly more favorable near the north end of proposed <br /> Buildings A&B. <br /> The final testing protocol was conducted on April 1 at the north end of proposed Buildings A&B. <br /> Percolation rates obtained for both Buildings were identical at 35.7 min/in. As with the south <br /> tests, these tests were conducted approximately 6.7-9.5 inches above the water table and again, <br /> illustrate acceptable permeability under saturated conditions. <br /> The Tables below summarize the data obtained from all the tests conducted. <br /> TABLE 1 <br /> PERCOLATION TEST"RESULTS FOR BUILDING E&E WITH CORRESPONDING <br /> TEST DEPTH ELEVATION, SOIL TYPE,PERCOLATION RATE AND <br /> APPLICATION RATE IN GALLONS/FTI DAY <br /> 24 INCH DEEP PERC TEST BORING,EL=6.54 83.3 min/inch / 0.123 gallons/W/day <br /> SILTY CLAY LOAM(CL-ML) <br /> 36 INCH DEEP PERC TEST BORING,EL.=9.19 50.0 min/inch / 0.311 gallons/ftZ/day <br /> SILTY CLAY LOAM CL-ML <br /> Application Rates adapted from Table 3 of the OWTS Policy of the SWRCB and is correlated with the Pero Rate obtained. <br /> TABLE 2 <br /> PERCOLATION TEST RESULTS FORBUILDING 'IV NORTH/SOUTH TESTS <br /> WITH CORRESPONDING TEST DEPTH ELEVATION,SOIL TYPE,' <br /> PERCOLATION RATE AND APPLICATION RATE IN GALLONS/FV/DAY <br /> 36 INCH DEEP NORTH PERC TEST BORING,EL.=7.16 35.7 min/inch / 0.467 gallons/W/day <br /> SILTY CLAY LOAM(CL-ML) <br /> 36 INCH DEEP SOUTH PERC TEST BORING,EL.=9.27 125 min/inch / 0.100 gallons/W/day <br /> LEAN CLAY CL <br /> Application Rates adapted from Table 3 of the OWTS Policy of the SWRCB and is correlated with the Perc Rate obtained. <br /> Page 2 of 3 <br /> Chesney Consulting <br />
