Per a call to David Junger around 2:25pm:
DeKalb County has no short-range plans to repave Sycamore Drive. The activity and markings we're seeing are all related to Atlanta Gas Light (AGL) trying to clean up its lines.
So, we're no longer under any tight time pressure to work on road calming measures via lane remarkings and possible parking markings, augmented by "turtles."
That said, it would still be wise to go ahead and work with the city and county to determine what we want, so it will be a standing plan, ready to be implemented whenever it makes sense and funding can be obtained.
