Our Athletic Complex is located right off of the main highway off ramp. The trucks that plow the off ramps for the State have been using the access loop at the front of the building as a turn around which they have done ever since the building was built, but now they are dropping their plows as they drive through. The problem is that when my crew's plow this loop they discharge the snow to the left away from the building and sidewalk which is on the right side of the road. The state trucks drive through and discharge the snow to the right and dump all the snow onto the sidewalk all along the front of the building. I then have to send a loader to take care of all this snow cause it melts and refreezes until it's moved. (Everything pitches away from the building to a drain in the road). I know I have every right to tell them to keep off our property but I really don't mind if they just drive through to turn around, I just don't want them to drop their plows making more work for my crew. My question is, How would you guys approach this situation? Do I flag down one of these guys, find out who the Foreman is and have a chat with him or do I get intouch with the State Supervisor and let him handle it??
