A. 
Loud Parties. Causing or permitting a gathering of two or more people on private property which is determined by law enforcement personnel at the scene to be a loud party in violation of this section because it is disruptive to the public peace, health, safety, or welfare due to the magnitude of the crowd, noise, disturbances, unruly behavior of those attending the party or gathering, excessive traffic or traffic congestion, illegally parked vehicles blocking other traffic or fire access or destruction of property.
