Emergency Operations Center

St. Charles County’s Emergency Operations Center (EOC) is a 30,000 square foot facility that houses all the County’s emergency functions previously located in different areas:

This is where the planning and coordination of disaster preparedness, response and recovery takes place; it is where staff answer and process 911 calls around the clock; and it is the hub for data technology. Bringing these services together in one building allows for a more coordinated and efficient response during an emergency. It makes our community a safer place.

The EOC opened in fall 2018 and is strategically located in O’Fallon, Mo., adjacent to the St. Charles County Police Department, at 1400 T.R. Hughes Blvd.
