Dictionary.com says, in part:
#2 seems to fit what you describe. There are penalties outlined for violating the ordinance, so that would serve to intimidate potential violators.enforce (ɪnˈfɔːs) [Click for IPA pronunciation guide]
1. to ensure observance of or obedience to (a law, decision, etc)
2. to impose (obedience, loyalty, etc) by or as by force
3. to emphasize or reinforce (an argument, demand, etc)
MCL 123.1102 makes no list of recourse available to it's violators. Ergo, it'd be left for the courts to sort out. Good luck with that!
