Some underground utility flags ("call before you dig") appeared in my front yard. A couple of days later there was some work done in the road in front of my house. A few days after that I removed the flags. The very next day they were back again. That was a week ago.
How do I know who requested them and when I can remove them? It could be any one of several utilities or four departments at two levels of government.
I know from experience these flags are never removed unless I remove them. They are on thin metal stakes that rust, fall into the lawn, and get sucked into lawn and snow equipment.
I am in NJ. I wrote to the agency that handles this, and if I get an answer I'll add an answer here.
