Overview

Most on-street barricades, lane closures, and formal crowd-control operations in Seattle require permits and approved traffic control plans. Permits for street closures and curb-to-curb impacts are managed through the Seattle Department of Transportation (SDOT) special-events and street-use processes SDOT Special Events[1]. Permits for events in city parks are handled by Seattle Parks and Recreation and have separate requirements for barricades and fenced footprints Seattle Parks Special Events[2]. The controlling municipal provisions and authority for city permits and right-of-way uses are published in the Seattle Municipal Code Seattle Municipal Code[3].

Pre-Event Coordination

  • Plan at least 60 to 120 days ahead for large street closures and complex traffic-control plans.
  • Confirm which permits apply (street use, special event, park permit) and collect required diagrams and insurance certificates.
  • Engage Seattle Police Department and SDOT for traffic control and public-safety coordination where public streets or large crowds are involved.
