Full Breakdown
County Code § 72.249.5 treats any festival, fair or carnival held wholly or partly within a street as a "special event" requiring a written permit from the Road Commissioner or Board of Supervisors before it can close or occupy the roadway. Organizers file 30 to 180 days ahead, post a security deposit for barricades, and carry liability insurance. A permit can be denied if the event is run purely for private profit rather than community benefit, or if it would unreasonably block traffic or emergency access. Street closures beyond 24 hours need Board of Supervisors sign-off.
Violations & Fines
Conducting or joining an unpermitted street fair, parade, or special event, or interfering with a permitted one, is a violation the Road Commissioner or Sheriff can cite; permits can also be revoked for noncompliance.
