The Chattahoochee River 911 Authority (ChatComm) serves the City 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.

A two-member board of directors oversees ChatComm, with each city manager having a single appointee. The two primary performance requirements for ChatComm are 911-call answer time and call processing time. The 911 Center is required to answer 90 percent of calls within 10 seconds and process 90 percent of those calls for dispatch within 60 seconds.

In addition to serving the cities of Sandy Springs and Johns Creek, the cities of Dunwoody and Brookhaven are current subscribers.


Smart911 is a free 9-1-1 information service available in Sandy Springs. Smart911 allows residents to enter information online that is delivered automatically to a 9-1-1 operator when a 9-1-1 call is placed. This same information can be accessed by emergency responders.
