Evacuation and shelter-in-place protective actions are prompted by a variety of threats and hazards. Incident-specific circumstances drive the relevant protective actions based on a community’s demographics, infrastructure, resources, authorities, and decision-making process. Determining that an evacuation needs to take place is not an all-or-nothing approach. Lessons learned from disasters, such as hurricanes Katrina, Harvey, Irma, and Maria, highlight the value of enacting a zone-phased approach to evacuation and shelter-in-place, enabling jurisdictions to move as few people as necessary. Sheltering-in-place populations that are not directly in harm’s way, rather than having them evacuate, helps jurisdictions reduce costs, resource requirements, and the negative impacts of evacuations, while promoting improved response and quicker re-entry and recovery.
