Large box installed in my front yard without consent

 Crews have been installing underground conduit along my street for several weeks. To my absolute horror, I came home from work today to find a massive, unsightly, obtrusive box in my front yard as tall as I am! No other lot seems to have this monstrosity. I was never informed that this was going to happen and strongly object to its placement without notification or consent. I want to speak to someone to discuss moving it. Who can I  call to get this taken care of?
