'J <br /> There was no standing water aftir the 24-hour soak <br /> g period In the four deep test borings,which all <br /> had passing rates. Therefore, Percolation EHD Test Procedure #2 was performed. The last half <br /> hour of the tests was witnessed day Lisa Medina of the San Joaquin County Environmental Health <br /> Department. <br /> The following Table summarizes and illustrates the proposed Parcel number and potential septic <br /> system structures based on dept hl of passing perc rates,proposed acreage, post soak period status <br /> and perc test results for the respective perc test depths: <br /> TABLE 1 <br /> r <br /> PER.

The 1999 Lines of <br /> Equal Elevation Map illustrates the groundwater elevation and the directional flow to be in a <br /> west, southwesterly direction. <br /> Unfortunately, no Well Driller's Log exist for the Tivald's on-site well. Consequently, <br /> underground lithology specific toithe subject property cannot be discerned. The property is not <br /> subject to 100-year flooding. Therefore, it is highly unlikely there would be surfacing of effluent <br /> from inundated conditions. Surface water will be managed by on-site retention basins. <br /> Chesney Consulting <br />
