<br />City of Santa Ana | First Street Multimodal Corridor <br />Technical Memorandum <br /> <br />43 <br /> <br />Concept Development <br />Based on feedback from the community, technical analysis and field assessments, three <br />Concepts were developed for the c orridor. 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 W orkshop 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 wer e integrated into all the concepts presented: <br />• New <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 I-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 />Figure 23. New Controlled Crossing at <br />Shelton Street
