From the Atlanta Journal Constitution: Dunwoody has a month to make sure it could still use its radio systems and how fire department calls would be handled if the city joins the 911 center that currently serves Sandy Springs and Johns Creek.

A draft deal calls for Dunwoody to pay $1.2 million a year for three years for the center, called ChatComm, to handle its emergency calls. The city would shell out $570,000 as a one-time payment for additional equipment and training. That’s about the same price the city expects it would spend to launch its own 911 network, which remains an option.

A determination wouldn't happen until next summer, since DeKalb County's newest city must give six months' notice if it leaves the county-run dispatch system.
