A person seeking issuance of a parade, special event, or outdoor demonstration permit shall file an application with the Chief of Police on forms provided by this office not less than 45 days before the date on which it is proposed to conduct the parade, special event, or outdoor demonstration. The Chief of Police may waive the minimum filing period and accept an application filed within a shorter period if, after due consideration of the date, time, place and nature of the parade, special event, or outdoor demonstration, the anticipated number of participants and the City services required in connection with the parade, special event, or outdoor demonstration, the Chief of Police determines that the waiver will not present a hazard to public safety.
