<br /> <br /> Environmental Checklist <br /> <br /> For CEQA Compliance <br /> proposed project in the region. The probability and consequences of such earthquakes are <br /> unknown, but they could result in minor structural damage and possible injuries, ranging up <br /> to large-scale destruction and possible fatalities. The proposed project includes fiscal <br /> mechanisms designed to attract new business and retain existing businesses and jobs in the <br /> most economically distressed areas of the city. The zone designation would not result in any <br /> specific construction project, demolition project, land acquisition project, or other <br /> development project. Such activities may occur from individual projects as an indirect result <br /> of the SEZ business incentives; however, these would occur in accordance with building and <br /> safety standards as specified by the City Building Division. All buildings would be <br /> constructed in compliance with the latest earthquake-resistant design and relevant codes <br /> available. Impacts are considered less than significant. <br /> A-3 Less-Than-Significant Impact. The term liquefaction describes a phenomenon in which a <br /> saturated, cohesionless soil loses strength and acquires a degree of mobility as a result of <br /> strong ground shaking during an earthquake. The factors known to influence liquefaction <br /> potential include soil type and depth, grain size, relative density, groundwater level, degree of <br /> saturation, and both the intensity and duration of ground shaking. The City has identified <br /> specific liquefaction areas that range between a very high to very low liquefaction potential <br /> (City of Santa Ana 1998:A-39). Generally, the southern and western areas of the city have a <br />high and high-medium liquefaction potential <br />whereas the central to northeast areas of cit <br /> , <br />y <br />have a low liquefaction potential. The proposed project includes fiscal mechanisms designed <br /> to attract new business and retain existing businesses and jobs in the most economically <br /> distressed areas of the city. Any specific construction project, demolition project, land <br /> acquisition project, or other development project that indirectly arise from the implementation <br /> of the SEZ would occur in accordance with building and safety standards as specified by the <br /> City Building Division. These standards inherently provide for measures to reduce the <br />t <br />ti <br />l i <br /> po <br />en <br />a <br />mpacts of liquefaction to structures. In addition, project sites within liquefaction <br /> zones would require specialized geotechnical analyses to address potential hazards, and the <br /> incorporation of design measures with oversight by the City Building Division. These <br /> technical studies would provide a more site-specific evaluation of the area and provide <br />additional design measures for site preparation <br />excavation <br />grading <br />and construction <br />This <br /> , <br />, <br />, <br />. <br />evaluation and design measures would also reduce potential impacts related to liquefaction. <br /> Therefore, potential impacts would be less than significant. <br />A-4 Less-Than-Significant Impact. The project area is generally flat and fully developed. The <br />proposed project includes fiscal mechanisms designed to attract new business and retain <br />existing businesses and jobs in the most economically distressed areas of the city. Any <br />specific construction project, demolition project, land acquisition project, or other <br />development project that indirectly arise from the implementation of the SEZ would occur in <br />accordance with building and safety standards, as specified by the City Building Division. <br />Therefore, potential impacts would be less than significant. <br />B. Less-Than-Significant Impact. The proposed project area is generally flat and fully <br />developed. Developed land generally has minimal amounts of erosion and usually does not <br />contribute to the loss of topsoil. Furthermore, the General Plan Land Use Element (1998) <br />identifies that an erosion hazard is associated mainly with soils along the Santa Ana River <br />and Santiago Creek (City of Santa Ana 1998:A-37). Since the Santa Ana River is mainly <br />channelized with concrete, erosion hazards only remain with Santiago Creek (City of Santa <br />Ana 1998:A-37). Santiago Creek is located in the northern part of the city. It runs partially <br />along the northeastern boundary of the proposed SEZ, and joins the Santa Ana River just <br />south of Garden Grove Boulevard.
