No person may use any public address system in any park or preserve without first obtaining a permit from the Director. Noise shall remain at a level that does not disturb the reasonable use of the park facilities by others. The determination of whether the noise level disturbs the reasonable use of the park facilities may be made by representatives of the Police or Parks and Recreation Departments, who may immediately revoke the permit. (Ord. No. G-5144, § 2, 2008)
