The Administration shall have the authority to revoke a special event permit immediately upon breach of the permit terms or conditions or permittee duties, or when any grounds for denying a permit as set forth in this article are found to exist. Cause for revocation shall include, but not be limited to, the failure to obtain, or the revocation of, other permits required for the special event. The Administration may revoke a special event permit when a public emergency arises and the police, fire, or EMS resources required for that emergency are so great that the deployment of police, fire, and EMS services for the special event would have an immediate and adverse effect upon the participants or the public health, safety, or welfare. The Administration shall state the reasons in writing for the revocation. Revocation or lack of a special event permit, including a failure to show proof of a special event permit, shall be cause for the Administration to order immediate termination and dispersion of a special event.
