Is the event/gathering temporary with an estimated attendance of 600 or more people outdoors, attending simultaneously?
Will the event/gathering result in the temporary closure or inaccessibility of a street, public way, road, highway, boulevard, parkway, lane, alley, service road, viaduct, bridge, sidewalk, or other public rights-of-way?
Are you responsible for operating an event/gathering or the property owner, as specified in the criteria above?
