PROPOSAL STANDARD AVENUE PROTECTED BIKE LANES 3RD TO WARNER City of Santa Ana Key Issues Bikeway Design Coordination of the bikeway project with the adjacent residential, commercial, and industrial uses will be important to address driveways and access issues for a safe and comfortable bikeway facility serving a broad range of users. Additionally, the project can link to the 3rd Street connector to Downtown, the Bishop- Willits Bike Boulevard, and future bikeways on Edinger Avenue, McFadden Avenue, St. Andrew Place, St. Gertrude Place, and Warner Avenue. The protected intersection design will establish the design for future integration with the McFadden Avenue cycletrack and needs to account for large vehicle turns serving heavy trucking and emergency vehicles. Our project team has begun evaluating the truck turning radius and is ready to work with the City to consider mountable truck apron that still protects vulnerable users traveling through the intersection. Mark Thomas has extensive experience designing Class IV protected bikeways, Class II buffered bike lanes, and Class III shared facilities. We have designed protected bikeways for the cities of Westminster, Sacramento, and Mountain View. We have a detailed understanding of the nuances of the design to provide for a safe and comfortable bicycle route. Large Vehicle Accommodation The project design will need to account for large vehicles that serve industrial uses south of Edinger Avenue with careful consideration of the visibility of cyclists at turning locations and driveways. Enhancements to shorten pedestrian crossing distances and curb modifications will need to be reviewed to serve truck turning radius by heavy trucking as well as emergency vehicles employed by the Orange County Fire Authority. Curb Extensions While portions of the project are focused on striping a bikeway and design of the separated bikeway, we will seek to incorporate curb extensions or bulb outs to shorten pedestrian crossings. The design will need to carefully balance the stormwater flow and ensure we do not create a low point that creates ponding and long- term maintenance issues. Stormwater Management Much of the corridor is very flat and storm event flooding along the project corridor and McFadden Avenue will need to be considered to avoid aggravating the condition. Our project team will seek solutions that can minimize the impacts of ponding and flooding while looking to incorporate infiltration through LID where acceptable to the City. Our team is well-practiced at working with regulatory agencies to address water quality requirements and securing needed permits. We are currently with the City of Westminster to install LIDs along Hoover Street as part of the Mendez Historic Trail & Green Street Project Bikeway. The design incorporates curb cuts and appropriate landscaping in bioswales to reduce stormwater flows to the storm drain system. 9
