From my perspective, this sort of came out of the blue. Portland Afoot has been doing a very good job of following the details.
But there’s one bit of logic in the timing that I can understand. TriMet is applying a “maintain existing revenue streams” approach. This was applied with lottery bonds. When the West Side MAX lottery bonds were paid off, TriMet convinced the legislature to continue the same bond repayment stream, now directing it to the bridge for the Milwaukie project.
I’m assuming the same logic applies here: the voters have been giving TriMet $8/100,000 for years, TriMet would like them not to stop.
