L /\ FAIRVIEw BRIDGE REPLACEMENT AND STREET IMPROVEMENTS J" (JTH STREET TO 16TH STREET) PROJECT INITIAL STUDY/MITIGATED NEGATIVE DECLARATION SANTA ANA, CALIFORNIA MAY 2020 Because the Project would add lane capacity to the Fairview Street bridge, some traffic currently using other routes would use a widened Fairview Street bridge, which would increase VMT in the area. On the other hand, the improved bridge may attract additional pedestrians and bicyclists due to added sidewalks and bikeways. Therefore, the proposed project would support nonmotorized travel. As such, the proposed Project would not conflict or be inconsistent with State CEQA Guidelines section §15064.3, subdivision (b). Impacts would be less than significant, and no mitigation is required. c. Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Less Than Significant Impact. The Project segment of Fairview Street bridge and the SART do not currently include hazardous design features, and operations of those facilities do not include any incompatible uses. The proposed Fairview Street bridge and SART modifications would be designed and constructed consistent with applicable CBC and Caltrans seismic design standards and would not include hazardous design features or incompatible uses. The construction of the proposed improvements would be completed with materials consistent with standard City requirements. Therefore, construction and operation of the proposed Project would not increase hazards due to a design feature or incompatible uses. This impact would be less than significant, and no mitigation is required. d. Would the project result in inadequate emergency access? Less Than Significant with Mitigation Incorporated. There are no hospitals, fire stations, or police stations on the Project segment of the Fairview Street bridge. However, Fairview Street provides a direct north -south route across the Santa Ana River in Santa Ana. Construction of the proposed Project would require temporary closure of one travel lane at a time on the bridge, which would temporarily delay local vehicular traffic and could temporarily affect emergency responders. Coordination with emergency responders with respect to reducing delays and identifying detour routes would avoid significant impacts with regards to emergency access. This requirement is included as part of the TMP specified in Mitigation Measure TR-1. Therefore, with implementation of Mitigation Measure TR-1, the proposed Project would not result in inadequate emergency access. 3.17.3 Mitigation Measures Mitigation Measure TR-1 Transportation Management Plan. During the construction phase, the Construction Contractor shall be required to submit a TMP to the City of Santa Ana (City) Director of Public Works, or designee, for review and approval. During construction, the City Director of Public Works, or designee, shall require the Construction Contractor to adhere to all requirements of the Traffic Management Plan (TMP). The TMP shall include the following: Notices of lane closures in local media and posted on the City's website. 3-102 R:\WKE1702\ISMND\Final ISM ND\Fairview Street Bridge Final ISMND.docx (05/26/20)
