City of Santa Ana Environmental Checklist future projects would have associated construction impacts with the potential to result in discharge of stormwater to surface waters, either directly or, more commonly, via a local stormwater collection system. All of these projects have been and would be required to comply with construction stormwater requirements of the local jurisdiction and compliance with the general NPDES permit for construction stormwater discharges. Furthermore, the BMPs and project design features identified in Response IX(a) would minimize runoff and erosion impacts on hydrology and water quality resulting from development of the proposed project. As discussed in Section IX, "Hydrology and Water Quality;" all impacts resulting from the proposed project related to hydrology and water quality would be less than significant. Thus, hydrology and water quality impacts related to the proposed project would be less than significant and would not be cumulatively considerable. Noise The cumulative study area for noise includes all the projects listed on the cumulative projects list (Table 3-26). Increases in noise in the vicinity of sensitive uses would occur during construction of the proposed project Simultaneous construction of the proposed projects and related projects in the vicinity of the proposed project area is not anticipated. As shown on Figure 3-3, no cumulative projects are in the immediate vicinity of the proposed project. The closest project is approximately one mile away from the project site. Noise from the proposed project would not create a cumulatively considerable impact if construction time frames overlapped. Therefore, construction noise from the proposed project is not anticipated to combine with construction noise from other projects, and construction noise from the proposed project would not be cumulatively considerable. Further, as described in Section XII, Noise, the City Municipal Code limits construction activities to between the hours of 7:00 a.m. and 8:00 p.m., Monday through Saturday, and also prohibits construction activities on Sundays and public holidays. Because compliance with this construction time limit is required by the City Municipal Code, the proposed project and all other cumulative development would be exempt, and the cumulative impact associated with construction noise in the Santa Ana area would be considered less than significant. Lastly, because construction-related noise generated under the proposed project would be mitigated by implementation of the noise control measures provided in NOl-1, construction of the project would not result in a cumulatively considerable impact. Cumulative noise impacts are considered for the buildout year 2035. The TIA was used to determine potential traffic-related noise impacts from the proposed project. The future roadway network surrounding the project site was modeled using the TNM noise model with the buildout year traffic volumes with and without the project. Table 3-27 below shows the project's contribution to the build out year. Table 3-27.
