Construction equipment left on my property—what do I do?

There’s been construction equipment on my property for months now—looks like a small company, maybe working on fiber lines. They’ve damaged part of the property and I haven’t been able to get in touch with them. It’s definitely not a city crew.

I’m not looking to escalate things legally if I can avoid it, but they’ve basically just dumped their stuff and vanished. Is this something for code enforcement? Police? Is there any chance I can get this resolved without a huge headache?

Would appreciate any advice from folks who’ve dealt with something like this.
