It's a civil and criminal matter.

If you are serious as to pursuing both or either...

1) Have your property surveyed. Have the licensed surveyor mark the line with clear stakes down the line in question. Video the damage and the signage.

2) Lawyer up. Be ready to spend a bunch. Sue the neighbor.

3) After you have reconstructed the property line, get estimates from tree and landscape places as to what they will charge to replace the damaged stuff, and repair what other damages there are. Take that dollar amount to the district attorney and file charges on the neighbor for felony destruction of private property.

4) While the legal survey stakes are in place, have a fencing crew put up a new, formidable fence. Good fences make for good neighbors.
