Crisis Event Response and Recovery Access (CERRA) Framework: An Emergency Preparedness Access Implementation and Best Practice Guide [open pdf - 5MB]
"This Framework builds upon prior and existing efforts by the Emergency Services Sector Coordinating Council (ESSCC) and multiple State and local crisis access and re-entry programs to cooperatively define a common approach based on best practices to enhance communities' preparation, response, recovery, and resilience efforts during incident management operations. This Framework is intended as voluntary guidance for SLTT [State, local, tribal, and territorial] government and law enforcement entities, when planning and developing an access management plan or program. The recommended common approach described in this Framework is meant to be integrated into a SLTT government's emergency preparedness planning in accordance with its use of the National Incident Management System (NIMS) and Incident Command System (ICS). The CERRA [Crisis Event Response and Recovery Access] Framework supports public, private, volunteer, and nongovernmental organizations (NGO) in facilitating their response and recovery efforts. It provides mechanisms, tools, and process approaches for coordinating, approving, and enabling access during response and recovery operations. The methods, tools, and templates presented in this Framework are intended to enable SLTT governments to define and establish local programs and approaches that can successfully interoperate nationwide. The CERRA Framework describes a common approach by which communities can:  Manage and control access for their jurisdiction;  Develop a consistent, repeatable process to coordinate with response and recovery organizations that require access to or transit through a restricted area or emergency zone;  Support outreach, education, and communication to ensure all stakeholders understand designated access requirements and procedures; and  Coordinate with law enforcement to implement access controls throughout an emergency."
