On January 1, 2016, Chamblee took over roadway maintenance from DeKalb County. As part of that maintenance takeover, Chamblee took over maintenance responsibility for 33 traffic signals including 15 signals on state routes. DeKalb County had previously maintained the signals on the state routes. Public Works asked GDOT and DeKalb County for a copy of the maintenance agreement between the two entities, but no one could produce an agreement. Chamblee and GDOT are currently operating without an agreement, which could create issues if not addressed in a timely manner.



The “Intergovernmental Agreement between The Georgia Department of Transportation (GDOT) and The City of Chamblee” outlines the maintenance responsibilities for traffic signals along State Routes within the city limits of Chamblee. GDOT has a Regional Traffic Operations Program (RTOP) that manages traffic signals along regionally significant corridors. The corridors affected by this agreement are SR 141/Peachtree Boulevard, SR 13/Buford Hwy, SR 155/Clairmont Road and Chamblee Tucker Road (Chamblee). Chamblee Tucker Road is included to coordinate signals along that corridor with the signals on Buford Highway and Peachtree Boulevard.


With the attached agreement, GDOT will be responsible for maintaining and updating traffic signal timing and coordination along the stated corridors. GDOT will be responsible for maintenance and repair of vehicle detectors, pedestrian detectors, communications and surveillance. Chamblee will remain the maintaining agency for all traffic signals within the city limits and will be responsible for maintenance and repair of all other components not outlined in the agreement such as traffic signal heads, pedestrian signal heads and traffic control cabinets. Chamblee is currently performing these responsibilities as part of our budgeted signal maintenance program. Currently, all material used by Public Works, for work performed on state routes, has been replaced in-kind by GDOT. This agreement does not explicitly state that GDOT will continue this practice of replacement in-kind but it also doesn’t explicitly say that this practice will be discontinued.



The 2017 signal maintenance budget was based on the City repairing and maintaining all 33 signals including state routes.
