In the event the amusement activity is not conducted on a paved or lawned area, the chief of police may require applicant to treat the area with some type of temporary ground cover, such as oil, wood chips, gravel or similar material that will inhibit and control dust. In making his or her determination under this chapter, the chief of police shall take into account such things as the amusement activity involved and the area being used, its proximity to other areas, and the length of time for which the permit is issued. (Ord. 304 § 13, 1972).
