Tree trimming

The trees on the undeveloped property adjoining mine have completely overgrown the XFinity lines that run pole to pole (NOT the drop lines to the house). I do not know who owns the property. The local power company has inspected the lines and confirmed they do not belong to them and my local government (Charlotte County, FL) has told me they do not trim trees. Neither the trees or the lines are on my property but are clearly visible from my property. I think I can assume the owner of this undeveloped land has no interest in trimming these trees. How do we get the lines cleared before a storm brings down the trees and the lines and knocks out the service in our Community?
