<br />City of Santa Ana | First Street Multimodal Corridor <br />Technical Memorandum <br /> <br />48 <br /> <br />Enhanced Pedestrian and Bicycle Zone Concept <br />This concept includes directional Class IV bikeways on each side of First Street (north and <br />south side) as well as a dedicated sidewalk. With 17’ feet within the pedestrian zone, there is <br />sufficient space to construct a physical barrier such as a plantable strip between the bikeway <br />and the sidewalk and provide trees along the curbline. Distinct color or texture on the <br />pavement could also be used to help delineate areas for pedestrians and bicycles . At 66’ <br />feet wide curb to curb, this concept is the narrowest of the three concepts developed. <br />Illustrations of this concept are provided in Figure 27. <br />This concept provides five travel lanes and left turn pockets at intersections . As shown in the <br />existing conditions section of this technical memorandum, the traffic volume in the <br />eastbound direction is higher than in the westbound direction in each peak hour as well as <br />over a 24-hour period. Therefore, this option removes one travel lane in the westbound <br />direction to provide the space within the pedestrian zone. Lane widths in this option are 10 to <br />11’ wide and the median is 12’ wide. <br />Figure 27. Illustrations of the Enhanced Pedestrian and Bicycle Concept
