It's generally not legal to block anyone from using a street for its intended purpose, be they a resident or not, unless it's an undedicated (private) street or a dead end road permitting no through traffic. Most streets are in a public right-of-way and it's hard to imagine the municipality would grant a permit allowing a permanent or recurring blocking of the road. Typically, that kind of permit is only granted for a one-time thing like a block party or a parade. So they city may have already acted contrary to law... and in doing so they are, in this case, also aiding this group of residents in running afoul of the Americans with Disabilities Act. This would be a really fun lawsuit, and just the hint of it coming would probably be enough to make the city rescind the permit.
