MARAC Region II Information
SEMS Mutual Aid Regional Advisory Committees (MARACs) were established to provide a broad base for local government participation in the Standardized Emergency Management System (SEMS) Maintenance System and are a principal source of input and information into the system. Recommendations from these committees to the SEMS Technical Group provide a means by which SEMS is maintained and improved. There are six MARACs, one for each of the six mutual aid regions. Responsibilities of the MARAC are to: adopt regional goals and objectives that support the development and implementation of SEMS; ensure that local governments, operational areas, special districts and other organizations, including the private sector and non-governmental organizations, are kept informed of the latest information on emergency management and on SEMS; recommend changes or modifications to SEMS to the SEMS Technical Group; provide personnel and/or technical support to SEMS Specialist Committees as appropriate; and ensure that local agencies and jurisdictions are provided the opportunity for ongoing comment and suggestions for system improvements.
