Soil borings were also conducted in a few of <br /> the lots, where equipment. access was possible , to determine <br /> the general soil types and water conditions . <br /> The locations of the borings and percolation tests are as <br /> ' shorn on the attaches sketches. Field locations were deter- <br /> mined <br /> by topographical features as well as staked lot corners. <br /> Surface elevations were interpolated from the contour elevations <br /> shown. on .the, preliminary plot furnished. <br /> Investigation Methods <br /> Heavy brush, trees, and slopes made it possible to conduct <br /> only a few of the borings, as well as percolation tests using <br /> a CME-45 truck-mounted power auger unit . These features made <br /> it necessary to drill a majority of the tests with hand augers . <br /> The soil classifications and depths as shown on the logs were <br /> inferred from the soils brought to the surface by the continuous <br /> flights of the auger. The depth of strata changes is thus <br /> considered approximate. <br /> CONSULTING ENGINEERS/SOILS AND MATERIALS <br /> Tsst Germ-^.•Foundnt+cn Enpinnannq and iib commnnel Lvon3•In;psction o4 Conturctwn•MAN.&-lemony of Sods.Conueta and t3uddmy Component3 <br />
