The Mayor shall not issue a parade permit as provided for in this article when, from a consideration of the application and from such other information as may otherwise be obtained, he finds that:
(a) The time, place, size or conduct of the parade including the assembly areas and route of march would unreasonably interfere with the public convenience and safe use of the streets and highways.
(b) The parade would require the diversion of so great a number of police officers to properly police the line of movement, assembly area and areas contiguous thereto so as to deny normal police protection to the Municipality.
(c) The parade route of march or assembly areas would unreasonably interfere with the movement of police vehicles, firefighting equipment or ambulance service to other areas of the Municipality.
(d) The parade would unreasonably interfere with another parade for which a permit has been issued.
(e) The information contained in the application is found to be false, misleading or incomplete in any material detail.
(f) An emergency such as a fire or storm would prevent the proper conduct of the parade.
