<br />1.0 INTRODUCTION
<br />This report presents the results of our subsurface exploration, geologic hazard, and preliminary
<br />geotechnical engineering smdy for che subject project. Our recommendations are preliminary
<br />in that definite building locations and construction details ha�• � not been final!ied at the time of
<br />this report. The location of the subject site is shown the Vicinity Map, Figure 1. The building
<br />lot boundaries, existing site topography, and the approximate loc:ations of the explorations
<br />accom�:lished for this study are presented �n the Site and Exploration Plan, Figure 2. In the
<br />event that any changes in the nature, design, or locations of the swctures are platmed, the
<br />conclusions and recommendations contained in this report should be reviewed and modified, or
<br />verified, as necessary.
<br />i.l I'urpose and Scone
<br />The purpose of this smdy ti�as to provide geotechnical design recommendations to be used in
<br />the preliminary design and development of the subject project. Our smdy included a review of
<br />available geologic literature, cxcaeation of exploration pits, drilling exploration borings, and
<br />performing geologic studies to assess the [ype, thic}:ness, distribution, and physical properties
<br />of the subsurface sediments and shallow ground water conditions. Geologic hazard e��aluations
<br />and geotechnical engineering studies were also conducted to assess suitable hazard mitieation
<br />options, the types of suitable foundations, allo�aable foundation soil bearing pressures, piling
<br />recommendations, anticipatr.d setQemrnts, basemendretaining wall lateral pressures, floor
<br />support recommendations, and drainage considerations. This report summarizes our current
<br />ficld�vork and offers development recommendations based on our present understanding of the
<br />rrojcct.
<br />1.2 Authorization
<br />�4'ritten autliorization to procecd with this study u�as gran[ed ���
<br />Belvedere, LLC. Our cwdy was accomplished in general accordance w�4� our scope of work
<br />letters dated June 13, 2003 and 7uly 31, 2003. This report has been prepared for the exclusive
<br />usc of Dch�edere, LLC and their agents, for sPecific application to this project. Within the
<br />limitations of scope, schedule, and budget, our scrvices have been performed in accordance
