L w FAIRVIEw BRIDGE REPLACEMENT AND STREET IMPROVEMENTS INITIAL STUDY/MITIGATED NEGATIVE DECLARATION <br />J' (9TH STREET TO 16TH STREET) PROJECT <br />MAY 2020 <br />SANTA ANAL CALIFORNIA <br />The future year No Project conditions (2021 and 2040) are the baselines for analyzing the impacts <br />associated with the Project itself (i.e., beyond that attributed to growth/cumulative projects). <br />2021 No Project Condition. As shown in Table 3.17.C, the intersections along Fairview Street are <br />anticipated to operate at acceptable LOS with the exception of the following intersections: <br />Fairview Street/17th Street (LOS E during the p.m. peak hour) <br />Fairview Street/9th Street (LOS F in both the a.m. and p.m. peak hours) <br />This represents a general worsening of intersection operations under 2021 No Project condition. <br />Table 3.17.C: 2021 Intersection LOS <br />2017 Existing Condition <br />2021 No Project Condition <br />2021 Plus Project Condition <br />AM Peak <br />PM Peak <br />AM Peak <br />PM Peak <br />AM Peak <br />PM Peak <br />Intersection <br />Hour <br />Hour <br />Hour <br />Hour <br />Hour <br />Hour <br />Vic <br />Vic <br />vac <br />vac <br />Vic <br />Vic <br />Delay <br />LOS <br />Delay <br />LOS <br />Delay <br />LOS <br />Delay <br />LOS <br />Delay <br />LOS <br />Delay <br />LOS <br />Fairview Street/ <br />1 <br />17th Street <br />0.835 <br />D <br />0.902 <br />E <br />0.853 <br />D <br />0.954 <br />E <br />0.860 <br />D <br />0.948 <br />E <br />Fairview Street/ <br />2 <br />16th Street' <br />31.6 <br />D <br />20.0 <br />C <br />33.9 <br />D <br />20.7 <br />C <br />>50.0 <br />F <br />27.2 <br />D <br />Fairview Street/ <br />3 <br />12th Street' <br />25.1 <br />D <br />19.0 <br />C <br />26.0 <br />D <br />19.7 <br />C <br />22.1 <br />C <br />18.0 <br />C <br />Fairview Street/ <br />4 <br />9th Street' <br />>50.0 <br />F <br />47.4 <br />E <br />>50.0 <br />F <br />>50.0 <br />F <br />>50.0 <br />F <br />41.4 <br />E <br />Fairview Street/ <br />5 <br />0.642 <br />B <br />0.640 <br />B <br />0.664 <br />B <br />0.651 <br />B <br />0.691 <br />B <br />0.665 <br />B <br />Civic Center Drive <br />= unsatisfactory LOS <br />' The intersection is unsignalized and was assessed using the HCM methodology. Delay values shown are in seconds per vehicle. <br />>50.0 = HCM delay value is greater than 50.0 seconds per vehicle, LOS F. LOS = level of service <br />HCM = Highway Capacity Manual v/c = volume -to -capacity ratio <br />As shown in Table 3.17-D, forecasted increases to daily traffic volumes along Fairview Street <br />from existing to 2021 No Project condition are anticipated to continue to result in unsatisfactory <br />roadway segment LOS for the four -lane segments of Fairview Street. <br />2021 Plus Project Condition. As shown in Table 3.17.C, the intersections along Fairview Street <br />are anticipated to operate at acceptable LOS with the exception of the following intersections: <br />Fairview Street/17th Street (LOS E during the p.m. peak hour) <br />Fairview Street/16th Street (LOS F during the a.m. peak hour) <br />Fairview Street/9th Street (LOS F during the a.m. peak hour and LOS E in the p.m. peak hour) <br />Several of the study intersections are shown to operate at higher levels of delay or capacity <br />compared to the 2021 No Project condition because of the rerouting of regional north -south <br />vehicular traffic from parallel routes that may now use Fairview Street due to the proposed <br />improvements.
