It appears that the city of Bradenton has been diligent in providing dropped curbs (and "bump zones") at intersections. The bumps are, presumably, for those who are blind or low vision and unaccompanied by a sighted companion or a dog.
I've only seen a handful of individuals like that in more than two decades here. There are, however, a number of people in wheelchairs and mobility scooters. The desire to create deep gutters for water run-off results in dropped-curb access that is unsuitable for wheelchairs.
Check out Riverfront Boulevard and Riverside Drive East, which my wife and I "navigated" this morning. It is impossible for a standard wheelchair to roll from the road to the curb without the footrests snagging on the ground.
I'm in the phone book. I'd welcome a call from a city council member to show him the problem in person.
