I suspect a lot of the problem is that no one on that board is a person who rides transit, much less depends on it, much less understands the fundamentals of building it well.
I also think this is the big challenge. I don't believe the board has any ill intent. However, it isn't comprised of actual users of the system or professionals in the field either.
I can't cut the board this much slack. The board has a fiduciary responsibility to perform adequate oversight and due diligence and not rubber stamp staff.
If they aren't up to the task, they shouldn't accept the appointment. But, if they do accept, they are effectively agreeing to bone up on the agency's activities, ask hard questions, do their homework, demand solid and appropriate support for presentations, bring in outside experts to help educate them and/or have third party consultants/experts assist in independent audits and evaluations. JEA's board failed in all these ways and JTA's board is now doing the same.
There are no excuses for not doing the job right. Disqualify yourself if you can't live up to your responsibilities or prepare to be embarrassed and shamed at some point as JEA board members learned the hard way.
