ENGEO <br /> <br />INCORPORATED <br /> <br />GEOLOGY <br /> <br />The geology of the site is described by William Lettis & Associates, Inc. in their report dated <br />March 26, 1999. Portions of their work are excerpted below. <br /> <br />The northern Calaveras fault traverses obliquely through the western part of the property. <br />Cretaceous sandstone and siltstone of the Panoche Formation (Dibblee, 1980; Crane, 1988) <br />underlies the area west of the fault and dips steeply to the southwest. Dibblee (1980) and Crane <br />(1988) map a thin sliver of Plio-Pleistocene gravel (Livermom Formation) between the fault and the <br />west-facing topographic break in slope and Quaternary alluvium east of the break in slope. Nilsen <br />(1975) maps the hill slope west of the site as underlain by landslide deposits, and Herd (1978) maps <br />a small landslide along the southem margin of the site. <br /> <br />Detailed studies conducted on the Yee property, directly south of the Lemoine property, show that <br />the Calaveras fault projects northwestward into the westem part of the project. Terrasearch (1998) <br />shows the northwest-trending trace of the Calaveras fault traversing the western part of the parcel, <br />with Cretaceous marine sediments on the southwestern side of the fault and Quaternary alluvium <br />underlying the gentle slopes in the central and eastern part of the parcel. <br /> <br />The small landslide along the southern portion of the site will be removed and buttressed during <br />mass grading at the site. <br /> <br />4992.5.001.01 <br />February28, 2003 3 DRAFT2 <br /> <br /> <br />
