Office of Emergency Services

The mission of the Office of Emergency Services is to lead efforts to prepare for, mitigate, respond to, and recover from disasters.


The Sheriff’s Office of Emergency Services (OES) provides emergency management services for the County/Operational Area including its eleven cities/towns and 300+ special districts. OES coordinates emergency operations activities among all the various local jurisdictions and develops written guidelines for emergency preparedness, response, recovery and mitigation to natural / man-made disasters, and technological disasters. The Sheriff’s OES is mandated by the California Emergency Services Act (Chapter 7, Division 1, Title 2 of Government Code) to serve as the liaison between the State and all the local government political subdivisions comprising Marin County.

The Office of Emergency Services establishes the Marin County / Operational Area Emergency Operations Center (EOC) when directed by County emergency management authority. An EOC is a location from which centralized emergency management can be performed during a major emergency or disaster. This center facilitates a coordinated response by the Director of Emergency Services, Emergency Management Staff and representatives from organizations that are assigned emergency management responsibilities. The level of EOC staffing will vary depending upon the specific emergency situation.

Marin Emergency Management Organization

Marin County Code Title 2 Chapter 2.99 Emergency Organization and Functions – Provides the legal basis necessary for Marin County to conduct emergency planning, response, and recovery operations and provides the framework for the Marin Operational Area Disaster & Citizens Corps Council (DC3).

Emergency Operations Center (EOC)

An EOC is a location from which centralized emergency management can be performed during a major emergency or disaster.  This EOC function facilitates a coordinated response by community, local, state, and federal agencies.  The level of EOC staffing depends upon the situation, but can range from 12 to 75 people.

Located in the Marin Commons, 1600 Los Gamos Drive, San Rafael, the EOC is adjacent to the Office of Emergency Services administrative area.  In an emergency, the EOC will be operational within approximately two hours.  The Sheriff's Communications Center (9-1-1) is located immediately adjacent to the EOC.  The EOC was moved to its current location in 2014.

Standardized Emergency Management System (SEMS)

Oes Marin Incident

The Standardized Emergency Management System (SEMS) is the system required by California Government Code Section 8607(a) for managing emergencies involving multiple jurisdictions and agencies and was developed as a result of the 1991 East Bay Hills Fire. All state government agencies must use SEMS when responding to multi-jurisdictional or multi-agency emergencies. All local government agencies must use SEMS in multi-jurisdictional or multi-agency emergency responses to be eligible for state reimbursement of response-related personnel costs.

SEMS has been established to provide effective management of multi-agency and Multi-jurisdictional emergencies in California. By standardizing key elements of the emergency management system, SEMS is intended to facilitate the flow of information within and between levels of the system and facilitate coordination among all responding agencies. SEMS is designed to be flexible and adaptable to the varied disasters that occur in California and to the needs of all emergency responders.

More information on SEMS can be found online at the California Office of Emergency Services.

National Incident Management System (NIMS)


The National Incident Management System (NIMS) is a nationwide standardized approach to incident management and response. Developed by the US Department of Homeland Security and released March 2004, it establishes a uniform set of processes and procedures that emergency responders at all levels of government will use to conduct response operations.

Training & Exercises

Oes Training Exercises

Emergency Management today is a continually evolving and rapidly changing industry that requires a constant and coordinated effort in training and exercises. As history has proven, catastrophic events have had significant impacts on all services and systems that support our society. Realizing that local governments are responsible for restoring these services and systems, in the most efficient and expeditious manner, the County of Marin has adopted the Marin OES Training Calendar. This program provides a comprehensive training management system that enables County employees to perform duties during times of disaster or emergency while acting in the capacity of Disaster Service Workers (DSW), Emergency Operations Center (EOC) staff, or Building Evacuation Team (BET) members. The Marin County OES manages the Marin OES Training Calendar with the support of the Board of Supervisors, the County Administrator, all department heads, managers, and employees.

The Sheriff’s OES offers support to local jurisdictions for training and exercises.
