For those who have been following along, I have an update. CAMPO have announced a meeting of the Transportation Policy Board on Monday, June 8. Agenda Item 6 reads as follows:
This action will defer $633 million in currently funded projects to be reallocated to the IH-35 Capital Express Project. Individual projects selected for deferral will be removed from the 2021-2024 Transportation Improvement Program but may be included in future TIP amendments as additional funding becomes available from state and federal sources.
I've attached an edited version of their spreadsheet, which initially looked as though it had been designed as a middle-school project. Under scenarios A, B and C, the recommendation is to defer funding for the N Walnut Creek Trail (I assume they mean Section 2, which continues east from Walnut Creek Park to I-35) until some unstated time in the future. You can sign up to speak at the meeting if you so wish, but it sounds like they have already made up their minds - don't expect the 'Big Loop' to be built anytime soon, or as CXAgent would say, 'in my lifetime'.
