Trees overhanging utility lines--cost of trimming
Has anyone here had Riverside Public Utilities trim trees on their property that overhang utility lines? I have some trees in my backyard whose branches touch and overhang the wires going from the utility pole to both my and my neighbors' houses. The trees are healthy and do not drop branches, and the lines are coated, so there is not an immediate danger.
I looked on the RPU website and it says that they do send someone out to inspect and subsequently trim as needed, but it isn't clear who has to pay for that (is it the homeowner or a utility service?). I'm not in a position to have any extra expenses right now, so I'm worried to call them myself in case they send someone out and then give me a huge bill. (This isn't to knock RPU--we've had only good experiences with them thus far.)
