If they are still working in your area they probably continue to do the same thing by moving signs around and then calling to tow. They know what they are doing.... If you need help looking up this stuff in TOPS there is a ddot approver and they probably would like to know they are approving permits and they need to issue a reminder of the rules perhaps.

OP - curious if DPW had photos uploaded to TicPixor if the NOI was issued with no photos taken.
