5.4 GEOLOGIC HAZARDS AND RESOURCES In July 2008, 72 projects 1 were being processed with the San Joaquin County Building Department. These projects were located in Acampo, Escalon,Farmington,French Camp, Linden,Lodi,Lockeford,Manteca, Ripon,Stockton, and Tracy. The types of projects included residential projects such as new residences,additions and remodels to existing residences,mobile home renovations,and pool construction;commercial projects such as administration buildings,barns, and a riding arena;light industrial projects such as storage buildings, spray booths, and warehouses; office projects such as building conversions and tenant improvements; and institutional projects such as classroom relocation and facilities to house animals (Raborn,2008). Because the LEC is a permitted use at the proposed site and would not result in significant adverse impacts that cannot be mitigated,and because the LEC's location is removed from the city limits (the site is 6 miles from Lodi s city center), impacts from the LEC would not likely combine with those from the projects being processed in the city limits to result in cumulative significant impacts. As described above,the LEC will not cause any adverse impacts to geological resources and will not cause an exposure of people or property to geological hazards. There are no minor impacts,in addition,that could combine cumulatively with those of other projects. 5.4.4 Mitigation Measures The following mitigation measures are proposed for the project: • Structures will be designed to meet seismic requirements of the 2007 CBC. Moreover, the design of plant structures and equipment will be in accordance with CBC Seismic requirements to withstand the ground motion of an MCE event. In addition, special design considerations will be made for proposed facilities,if warranted,by the findings from any geotechnical investigation that will be conducted prior to construction. • A geotechnical engineer will be assigned to the project to carry out the duties required by the California Energy Commission (CEC) to assess geologic conditions during construction and approve actual mitigation measures used to protect the facility from geologic hazards. • If expansive soils are identified at the site, they can be mitigated by either removal or replacement with non-expansive soil or by blending with non-expansive soil under the supervision and direction of a geotechnical engineer. With the implementation of these mitigation measures,the LEC will not result in significant direct,indirect,or cumulative geology-related impacts. 5.4.5 Laws, Ordinances, Regulations, and Standards The LORS that may apply to geologic resources and hazards are summarized in Table 5.4-1. The local LORS discussed in this section are certain ordinances,plans, or policies of the San Joaquin County and the City of Lodi. 1 For the purposes of this discussion,San Joaquin County sorted its projects by project cost,and provided a list of the projects costing$25,000 or more. 5.4-10 SAC/371322/082330011(LEC-5.4-GEOLOGIC HAZARDS AND RESOURCES.DOC)
