Alternative 4 – Elevated Two-way Separated Bikeway with Landscaping The BPTC reviewed the seven alternatives at its September 2019 meeting, including cost estimates and a summary of the information obtained from three community engagement events held to gather public input on the plans. The BPTC recommended two alternatives for further refinement and study: • A one-way separated bikeway along most sections of West Las Positas and a two-way separated bikeway through the highest collision areas (a combination of Alternatives 1A and 3B) and • An elevated two-way separated bikeway throughout the corridor located exclusively on the south side (Alternative 4) The BPTC reviewed refined versions and cost estimates for the two final options at its December 2019 meeting. While there was support for the Alternative 4, elevated two-way separated bikeway, its higher cost ($14 Million), lead the BPTC to support the concept of a one - way separated bikeway along most sections of West Las Positas and a two-way separated bikeway through the highest collision areas (combined Alternatives 1A-3B), with an estimated $10 Million cost. The Committee cited several reasons for the selection of the combined Alternatives 1 A-3B. As well as the lower overall cost, but more importantly, the Committee cited the ability to construct the entire corridor with a “quick build” approach allowing for a more immediate completion of the corridor and the opportunity to upgrade to a concrete and planter design when funding became available. At its January 2020 meeting, the BPTC considered additional analysis and data regarding the proposed design and recommended eliminating the two-way separated bikeway element due to the short length of the two-way segment (only 1,500 feet in length on the south side of West Las Positas between Fairlands Drive and Owens Drive). Short sections of two-way sections are not commonly used, as they would require additional crossings. The BPTC recommended the revised version move forward, including the elimination of the two-way cycle track section as suggested by staff. Public Outreach and Committee Participation Public engagement was integral to the Corridor planning process, and yielded input that was factored into the alternatives and final design. Outreach included: • Receipt of public comments and input during each of the BP TC meetings. The BPTC reviewed the project at six separate meetings during the 15 -month project.
