The Chattahoochee River 911 Authority (aka "ChatComm") serves Johns Creek as its 911 Emergency Call Center. ChatComm was created in 2009, a joint effort by the cities of Sandy Springs and Johns Creek. It is operated following the Public-Private model with iXP Georgia, LLC managing the day-to-day operations. In addition to serving the cities of Sandy Springs (which uses the North Fulton Regional Radio System Authority P25 system) and Johns Creek, the cities of Dunwoody and Brookhaven (each of which use the DeKalb County 25 system) are also dispatched by ChatComm.
