You get them to conform by passing laws at the state level to take power away from the local residents. I know they wont comply, we have already seen the problems that giving local control creates in this scenario, so the solution is to make a decision for the larger and long term good.
Well sure they will fight, but thats not a good enough reason to not do something. Hopefully the state government has enough political capital to deal with the fight that the relatively small population of homeowners will put up.
