F31J� OCTA I Santa Ana/Garden Grove Fixed Guideway Project <br />Visual Impact Analysis Re-evaluation Technical Memo <br />vertical elements, other than poles and overheadwires that would conflict with the views of the <br />truss and the visual features of the existing bridge. Therefore, views in the vicinity of the existing <br />bridge would not be substantially di minis hed and the resulting impact was determined to be not <br />adverse/less than significant. Figure 4 depicts the existing bridge and the approved bridge <br />design in the LPA. <br />Figure 4. Santa Ana River Bridge (Existing and Approved LPA) <br />Currently, minor design modifications to the bridge crossing include a double track configuration <br />(rather than single track), use of two catenarywires as opposed to one, and the re -positioning of <br />the bridge to north of the existing Old Pacific Electric Santa Ana River Bridge (as opposed to the <br />south which was the previously -contemplated location of the new bridge). <br />To assess these minor design modifications, visual simulations were prepared for vantages <br />(e.g. from the south) similar to those identified in the 2015 EA. In addition, because the bridge is <br />re -positioned north of the Old Pacific Electric Santa Ana River Bridge, an additional vantage <br />was captured from the north. Figure 5 illustrates the keyobservation points that were used for <br />the two simulations. <br />Figure 5 — Key Observation Points <br />61 Page <br />
