A local business owner bought up one of the blocks in the center of the street and announced plans to demolish it in order to build a 5-over-1 complex several stories higher than any of the other buildings.
Without the public comment process, he'd have been able to do this practically overnight, completely ruining the street. The public fought back long and hard for many months and eventually won by convincing the town council to vote against the rezoning that would permit this construction.
I can't say I'm opposed to the public comment process.
(Note that this was not a case of never-change NIMBYism; tons of other similar buildings are going up all over the town completely unopposed. It was the ugly, generic design and the sheer size put so blatantly in the middle of everyone's favorite part of town.)
