Roth Quality Homes JN 90016 January 25 , 1990 Page 2 The site is currently undeveloped and is covered with tall gr�ss , blackberry vines , and small deciduous trees . Concrete debris have been dumped on the site in several locations . The properties surrounding the site have been developed with single-family residences . Lot 38 , immediately east of the site, is currently undeveloped. SUBSURFACE The subsurface conditions were explored by three test pits at the approximate locations shown on the Soils Exploration Plan, Plate 2 . The field exploration program was based upon the proposed construction and required design criteria , site topography and access , subsurface conditions revealed during . excavation, our proposed scope of work, and time and budget constraints . • The test pits were excavated on January 15 , 1990 with a rubber-tired backhoe owned and operated by Evans Brothers Excavating. A geotechnical engineer from our staff observed the excavation process, logged the test pits, and obtained representative samples of the soils encountered. "Grab" samples of selected subsurface soils were collected from the backhoe bucket. The Test Pit Logs are attached to this report as Plates 3 and 4 . The test pits encountered loose, silty sand fill and silt immediately below the surface organics. The fill was encountered in Test Pit 1 only, and probably resulted from the earlier construction of Edgemoor Lane. The loose silt was found to a depth of between three and one-half feet and eight and one-half feet below the existing �round surface. The loose silt had a mottled color, contained roots and other organics , and had a jumbled appearance. These soils are probably the result of erosion or sloughing of soils from the slopes above the site, and are referred to as slopewash in this report. Very stiff to hard, native silt was encountered below the slopewash soils . The final logs represent our interpretations of the field logs and laboratory classifications . The stratification lines on the loqs represent the approximate boundary between soil types . In actuality, the transition may be gradual . The relative densities and moisture descriptions indicated on the test pit logs are interpretative descriptions based on the GEOTECH CONSULTANTS , INC. .
