ESF 5 helps maintain situational awareness of the threat or incident. It serves as the coordination ESF for all St. Louis County government departments across the spectrum of domestic incident management from hazard mitigation and preparedness to response and recovery.  It will identify resources for alert, activation and subsequent deployment for quick and effective response.

During the post-incident response phase, ESF 5 is responsible for the support and planning functions. ESF 5 activities include those functions that are critical to support and facilitate multi-agency planning and coordination for operations involving incidents requiring local coordination.
