<br /> Soil Borings
<br /> On September 10, 2014 through January 26, 2015, Live Oak excavated shallow or
<br /> shallow and deep soil borings on Parcels 1 through 15 of the Site for the purpose of
<br /> conducting percolation tests. The borings were four inches in diameter, 3.20 to 23.70
<br /> feet deep, and were excavated by hand auger (Table 2). The locations of the borings
<br /> are indicated on Plate 10. Two percolation tests were conducted on Parcel 2 due to an
<br /> error in the field.
<br /> The soils in the borings were similar to those described by the Soil Survey. At locations
<br /> P1 through P5, clayey silt was encountered to the full depth of each boring, 3.27 to 3.35
<br /> feet. At location P6, sandy silt, sandy, clayey silt, and silty sand were encountered to
<br /> the full depth of the boring, 10.30 feet. At location P7, sandy silt was encountered to a
<br /> depth of 10.0 feet, followed by sand to the full depth of the boring, 15.00 feet. At
<br /> location P8, sandy, clayey silt was encountered to the full depth of the boring, 3.40 feet.
<br /> At locations P9, P10, P13, P14, and P15, cobbles with clay were encountered to a
<br /> depth of 5.0 feet, followed by clayey silt to the full depth of the borings (5.00 to 18.3
<br /> feet). At location P11, sandy, clayey silt was encountered to a depth of 8.0 feet,
<br /> followed by sand with gravel to the full depth of the boring, 9.00 feet. At location P12,
<br /> cobbles with silty sand were encountered to a depth of 3.0 feet, followed by clayey silt to
<br /> a depth of 21.0 feet, followed by fine sand to the full depth of the boring, 23.70 feet.
<br /> The logs for the soil borings are presented in Plates 11 through 18.
