Our scope of services consisted of: . Review of previously prepared geotechnical/geologic reports and geologic maps pertinent to the site (Appendix A). . A subsurface field investigation consisring of Yhe excavation, sampling, and logging of three (3) hand-auger bores, to depths rangin� from approximately 2%z feet to 3 feet. Approximate bore locations are depicted on the Geotechnical Map, Plate 1. The bores were excavated to evaluate the general characteristics of the subsurface soil on the site including classification of site soil, detennination of depth to groundwater (if present), and to obtain representative soil samples. . Geologic mapping of the site. . A review of laboratory testing of representative soil satnples obtained during the previous subsurface exploration. �. Engineering and geologic analysis of the data with respect to the design and construction of the proposed parking lotexpansion. . Preparation of General Earthwork and Grading Specifications (Appendix B). . Preparation of this report presenting our review, conclusions and preliminary geotechnical design recommendations for the design and construction of the proposed development. 1.2 Loeation and Site Descrintion The subject site is located aY the corner of Diaz Road and Business Park Drive, bounded on the north by the existing Outdoor Channel building and on the east and west by asphaltic concrete roadway. The general location and configuration of the site is shown on the Site Location Map (Figure L). An existing easement bisects the site on a north to south trend and on the east to west, extending from Diaz Road to Business Park Drive, along the northern edge of the property. The site appears to have been elevated by previous placement of till materials, undocumented. The topography of the site is gently sloping to the west at a general elevation ranging from approximately I L 18 to I L 15 feet above inean sea level (msl) within the site. • Project No. M I 109-001 Page l January 8, 2012 �:��,� �a� ,�,�t�-, �� . . ��,�' � � '--��' �'� "t��' � �.h a; �e� e�' i'� ;�.: �n5,��n a.? �v,� ��#V � � � �� , �H �F �x ��4 �� 4 � � d �{.2 f ' . .. -, sr � t � ��, �r : : {j� �'� °��"� �. {. �"'� ` _ v v � :� �.� u � � 3 � + ��'� �` .`, e� � � � a �� . m I�'� i� � �°A E �'�� . a `` .

Reports • Based on our background review previous geotechnical reports have been conducted on the site by Engen, 1997, 1998 and Schaefer Dixon AssociaYes, Inc., 1989 and 1990. Report copies were reviewed by Matrix Geoteclmical Consulting and incorporated into our conclusions and recoininendations for the site (referenced in Appendix A). 1.4 Proposed Develonment and Gradink It is our understanding that the proposed development is to be a parking lot The preliminary configuraCion of the development is shown on the Geotechnical Map, Plate 1. Grading plans were noY provided for tliis investigation, however, once grading plans become available, MATRIX should review the proposed development and provide supplemental recommendations/information as necessary. 1.5 Previous Report Review and Subsurface lnvestigation A prior consultant perfonned the most current geotechnical report of the adjacent site in 1998. The report coneluded that approximately four (4) feet of compacted fill was placed in the area of 2 newly proposed buildings. Additionally, the report stated that previous fault trenching was perfonned directly adjacent to the property in the landscape area on the north edge of the property, in July of 1997. Froin the Engen report, these fault trenches were backfilled with loose soil and not compacted. � 2.0 GEOTECHN/CAL CONDITIONS 2.1 Re,Yional Geo[opv Regionally, the site is located in the Peninsular Ranges Geomorphic Province of California. The Peniusular Ranges are characterized by steep, elongated valleys that trend west to northwest. The mountainous regions are underlain by Pre-Cretaceous, metasedimenTary and metavolcanic rocks and Cretaceous plutonic rocks of the Southem California Batholith. Tertiary and Quatemary rocks are generally coinprised of non-marine and marine sediments consisting of sandstone, mudstones, conglomerates, and occasional volcanic units. 2.2 Local Geoloxy Based upon our understanding of the regional area, a review of the geotechnical bore logs, and review of the previous reporting the earth materials on the site are comprised of undocumented artificial fill, residual soil, Quaternary alluvium, and Tertiary Torrey Sandstone. A general description of the earth materials observed on the site is provided in the following paragraphs: Fil1 Material, Undocumented (Afu): Undocumented artificial fill was encountered within the existing residential pad and driveway areas within approximately 1 foot of the ground surface. This soil consists predominately of light brown, dry to damp, inedium dense silty sand. � Project No. M1114-007 Page 3 May 16, 20L2 � Quaternary Alluviuin (inap symbol Qal): Quaternary young alluviuin was mapped within the drainage channel and low-relief portions of the site to an estimated depth of 4 to 6 feet below existing surface. These alluvial deposits consist predominately of silty sand and sand which are generally light brown to dark brown, damp to moist, and loose to medium dense. 2.3 Landslides Our review of the pertinent geologic literature did not indicate the presence of landslides on or directly adjacent to the site. 2.4 Groundwater Groundwater was not encountered during the currenY subsurface investigation to the inaximum explored depth of 35 feet below existing ground surface. 2.5 Surface Water Surface water runoff should be directed away from planned structures. The design of surface drainage is the responsibility of the project civil engineer. 2.6 Slope Stabilitv The site is gently sloping and we understand that significant slopes are not proposed to develop the � site for its intended use. Once final grading plans becoine available, MATRIX should review the proposed development and provide supplemental recomtnendations regarding slope stability as necessary. 2J Laboratory Testing From our review of the previous reporting, laboratory testing of the onsite soil consisted of representative samples obtained froin post-grading of the site. The following tests were perfonned: in-situ density and moisture content and R-value. These results should be confinned at the coinpletion of site grading perforined by the engineering geologist/geotechnical engineer's on site representative. • Project No. M I 1 14-007 Page 4 May 16, 2012 Water Quality Management Plan (WQMP) Outdoor Channel • 85` Percentile 24 hour Storm Event Isohyetal Map � .
