I live at 2200 NW 11th Ave. In the right-of-way on NW 22nd St I maintain a tall hedge as a visual buffer. There is a low-hanging cable that appears to be phone or cable (that does not pose any public safety issue) that the hedge has grown around. I would like to top the hedge so that it is not an issue, but I'm afraid of cutting the cable in the process. Can the cable be tightened and/or removed? This may be a question for COX, AT&T or GRU, but I'm starting here.
