Does any one know what is done for tightening base plate anchor bolts at traffic lights / signs/ light poles?  I have a single pole canopy with a similar situation - lateral loads due to wind and seismic and anchor bolts subject to periodic tension loads - no concrete cover on base plate.  In those situations, are anchor bolts tensioned or just tightened snug?
Thanks in advance -
