FN City of Santa Ana I First Street Multimodal Corridor <br /> Technical Memorandum <br /> Concept Development <br /> Based on feedback from the community,technical analysis and field assessments,three <br /> Concepts were developed for the corridor. Conceptual layouts in plan view, illustrative <br /> renderings and cross sections were developed to illustrate the components of the design <br /> concepts that were then shared with the public during Workshop 3. <br /> Technical analysis, including traffic modeling and pedestrian / bicycle analysis, was <br /> conducted to assess the benefits of each alternative compared to the existing conditions. <br /> In response to the existing conditions assessment and concerns about safety and pedestrian <br /> access,the following features were integrated into all the concepts presented: <br /> • New MR h1 <br /> w <br /> 4M why <br /> 1 � <br /> Figure 23. New Controlled Crossing at <br /> Shelton Street <br /> Mid-Block Crossings—These four <br /> crossings are proposed at Shelton Street, Booth Street, west of Wright Street and <br /> between Golden Circle Drive and Tustin Avenue. Each location would be equipped <br /> with a HAWK signal, high visibility markings and signage and a paved area in the <br /> median as a refuge island, as shown in Figure 23. With these crossings,the average <br /> distance between controlled crossings is approximately 0.25 miles and a controlled <br /> crossing is located at or near an existing bus stop. <br /> • Tighter Curb Radius— Most existing curb radii are 35' with some larger such as at <br /> the 1-5 southbound ramps. For all City intersections,the curb radius is tightened to <br /> 25', which slows the turning speed of vehicles and improves safety for pedestrians. <br /> • High Visibility Crosswalks —At all signalized intersections and on STOP controlled <br /> side streets, high visibility bicycle crossing and crosswalks are recommended. <br /> Continental style with high retro reflectivity is recommended for maximum visibility at <br /> night. Crosswalks near school zones should be evaluated for yellow markings and <br /> signage. <br /> 43 <br />
