<br />arrfA <br /> <br />Responses to <br />Environmental Checklist <br />For CEQA Compliance <br /> <br />No Impact <br /> <br />According to the City's Updated General Plan Land Use Element EIR, there are no areas in Santa Ana <br />that are designated significant Mineral Aggregate Resource Areas. Therefore, implementation of the <br />proposed project would not result in the loss of any regionally or locally important mineral resource. <br /> <br />XI. Noise <br /> <br />A. Exposure of persons to or generation of noise levels in excess of standards established in <br />local general plan or noise ordinance, or applicable standards of other agencies. <br /> <br />c. A substantial permanent increase in ambient noise levels in the project vicinity above <br />levels existing without the project. <br /> <br />Less Than Significant Impact <br /> <br />The project site is subject to noise standards and guidelines in the General Plan Noise Element and <br />Municipal Code Noise Ordinance. The primary purpose of the City of Santa Ana Noise Element is to <br />"Prevent significant increases in noise levels in the community and minimize the adverse effects of <br />currently-existing noise sources." In accordance with the Noise Element, the City has adopted noise <br />standards and guidelines for land use planning. These guidelines for exterior noise levels are presented <br />in Table N-1. <br /> <br />Table N-1 <br />Ci Of Santa Ana Land Use Guidelines For Exterior Noise <br />land Use Noise level dBA CNEl or ldn <br />Desirable Maximum Maximum Acce table <br />55 65 <br />60 65 <br />65 70 <br />60 70 <br />65 75 <br />70 75 <br /> <br /> <br />A significant noise impact would occur if a proposed land uses does not comply with the General Plan <br />noise standards identified in Table N-1, or when a proposed land use results in an 3dB increase to <br />existing noise levels when the existing noise level is at least 65 dB CNEL. <br /> <br />The operation of the proposed project would not significantly increase noise levels within the project site. <br />A significant increase in noise would be a 3dB increase over existing noise levels. Typically, a 3db <br />increase in noise levels could occur when existing traffic volumes are more than doubled. Since there <br />are no sensitive receptors in the immediate area of the parking lots, implementation of the proposed <br />project would not result in a 3db increase to existing noise levels within the project area. <br /> <br />B. Exposure of persons to or generation of excessive groundborne vibration or groundborne <br />noise levels. <br /> <br />D. A substantial temporary or periodic increase in ambient noise levels in the project vicinity <br />above levels existing without project. <br /> <br />75C-102 <br /> <br />9 <br />
