<br />GEe 15130 - Pagel <br /> <br />We recommend that an R-value of about 20 be used for the design of street <br />pavement sections constructed on the on-site inorganic soils. This R-value <br />is based on the assumption that the subgrade in street areas will be coarse <br />alluvium soils. <br /> <br />GENERAL <br /> <br />Waterbearing soils were encountered in some of the borings. This was the <br />case in borings 12, #4, and #5 that were drilled in topographically lower <br />or depressed areas. Such soils may be encountered elsewhere at the site. <br />Excavations made in areas where waterbearing soils are encountered may need <br />to be done with backhoe type equipment - vs. track or wheel type equipment. <br />Disturbance of these soils by track or wheel traffic may necessitate their. <br />removal from below proposed houses and streets. Dewatering may be required <br />in some excavations. <br /> <br />CLOSURE <br /> <br />To protect the addressee, the public, and ourselves, this report (and all <br />supporting information) is provided for the addressee's own use.
