This closure was due to safety hazards caused by improvements associated with the <br />original Santa Ana Second Main Line Track project. Large trucks making left turns from Fairhaven Avenue <br />onto Lincoln Avenue had insufficient turning radii and could not cornplete the turn, leaving there stopped <br />across the railroad tracks. Ater the city placed temporary barriers this hazard p <br />p r was resolved. This project <br />would not change the existing closed condition of this intersection and therefore would not increase traffic <br />hazards. The proposed project would continue the existing closed condition by modifying <br />Fairhaven/Lincoln intersection from the <br />n rrM <br />two lanes to a permanently closed intersection with a cul -de -sac. This <br />modification would prohibit al traffic traveling northbound on Lincoln Avenue from Park Avenue to Fairhaven <br />Avenue. As a result, the proposed project would result in a net benefit to safety conditions at this intersection <br />compared to the 2007 conditions. <br />Table 5.3-11 compares the hazard index at the rail crossings under two scenarios: Fairhaven/Lincoln <br />intersection open (two-way traffic - 2007 condition) and Fairhaven /Lincoln Intersection closed eistin and <br />project condition) . shown in Table . -11, the project would decrease the g <br />p � hazard index at Fairhaven and <br />1 7th Street and slightly increase the hazard index at Santa Clara Avenue compared to when the intersection <br />was open to two -way traffic. The Santa Clara Avenue index does not account for the increased safety <br />provided by the proposed traffic signal, Because the project would not substantially increase the hazard <br />index the project would not substantially increase the nurnber of vehicle /train conflicts at the rail cross in s. <br />Hazard impacts would be less than significant. 9 <br />Table 5.3-11 <br />Grade Crossing Hazard index wr"tb ro "e t <br />Hazard Index <br />Crossing Openi Closed, <br />Fairhaven Avenue 48 0 <br />Santa Clara Avenue 45 51, <br />17th Street 205 250 <br />Source: DMJM Harris 2008 <br />' Based on traff is volumes with the Fairhaven Avenue intersection open to two -war traffic. <br />Based on traffic volumes with the Fairhaven Avenue intersection closed. <br />3 Does not account for increased safety provided by new traffic signal. <br />CC13 <br />ai,rha er L,inco ln eind {Santa ClaralLincoln Intersection Modifications City of Santa Ana 0 Page 5.3-15 <br />SuPlement to the Savta Ana Second Main Track Project I Resolution N. 2 - <br />0 009 03 4 <br />Page 93 of 130 <br />
