L S A FAIRVIEW BRIDGE REPLACEMENT AND STREET IMPROVEMENTS (9TH STREET TO 16TH STREET( PROJECT INITIAL STUDY/MITIGATED NEGATIVE DECLARATION SANTA ANAL CALIFORNIA MAY 2020 to Figures 3a and 3b for the detour plans). There are gates and ramps located on both sides of the SART at 5th Street that provide access to bicyclists and pedestrians for these detours. Details regarding the detour are being coordinated with Orange County (OC) Parks. Other short-term closures of up to 15 minutes would be allowed with flagmen. A temporary detour within the riverbed may be required as a contingency. This would involve construction of dirt and gravel ramps with asphalt topping to and from the SART and the riverbed as shown on Figure 2. Construction vehicles would access the Santa Ana River from the gate and ramp at the County of Orange access road at the northwest corner of the bridge, and would use the existing concrete access ramp into the river approximately 250 ft west of the Project area (Figure 2). All access roads to the SART that are utilized by construction vehicles or for detour routes would be reconstructed and restored to preconstruction conditions or better prior to Project completion. 9. Surrounding Land Uses and Setting: The Fairview Street bridge spans the Santa Ana River. The SART (Class I bikeway; i.e., an off- street bikeway) runs on the east side of the Santa Ana River. In addition, Fairview Street is surrounded by a variety of land uses, including single-family and multifamily residences, parks, restaurants, commercial uses, light industrial uses, and vacant lands. 10.
