How to identify the Purple Zone

This is an optional step that addresses a specific scenario in which fire impacts a small fraction of the community.

The Red Zone might be divided into sectors to further develop likely community exposure scenarios (including size of wildfire front and relationships to egress arteries) where partial community evacuations (or partial sheltering in community) may be appropriate. In these cases, the community might determine if any Purple Zones can be developed.

Purple Zones are reserved for fire ignitions near or within the community where local conditions will contain the fire to only part of the community. Specific consideration should be given to spot fire ignitions within the community and the availability of resources to control the initial fire and any spot fires. Fires that ignite within the Purple Zones may still require large (complete community) evacuations if they develop into community conflagrations or occur during a fire storm when multiple regional fires coincide with a high wind event and first responder resources are extended on multiple incidents.
