5. Environmental Analysis NoisE City of Santa Ana Construction Hours The City of Santa Ana exempts noise associated with construction, repair, remodeling, or grading of any real es from the noise limitations of the Municipal code , provi ded that construction activities do not take place between the hours of 8:00 PM and 7;60 on weekdays, including aturd s, or an time Sundays or federal holidays. on 5,2.5 Thresholds of Significance According to Appendix G of the CEA Guidelines, a project would normally have a significant effect on he environment if the project would result in: N -i Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. N-2 Exposure of persons to or generation of excessive groundborne vibration or 9 roundborne noise levels. N -3 A substantial Permanent increase in ambient noise levels in the project vicinity above level existing without the project. N -4 A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project. N -6 For a project located within an airport land use plan or where such a plan has not been adapted, within two miles of a public airport or pubic use airport, expose people residing or working in the project area to excessive noise levels. N-6 For a project within the vicinity of a private airstrip, expose people residing or working the project area to excessive noise levels. The Initial Study, included as Appendix A, substantiates that impacts associated with the following thresholds would be less than significant: * Threshold N; 0 Threshold N -6 0 Threshold - These impacts will not be addressed in the following analysis. 5.2.4 Environmental Impacts The following impact analysis addresses thresholds of significance for which the Initial Study identified Potentially significant impacts. The applicable thresholds are identified in brackets after the impact statement. IMPACT 5. -1 INTERSECTION MODIFICATIONS WOULD NOT RESULT IN SIGNIFICANT PERMANENT NOISE IMPACTS. [THRESHOLDS N.1 AND N.3] ] Impact Analysis: Potential noise impacts from project- related traffic were evaluated to assess increases in the ambient noise environment in the vicinity of noise - sensitive receptors, Project-related traffic noise was Page 5.2-8 P The Planning Center Resolution No. 2009 -034 Page 74 of 130 March 2009
