I regularly walk a short route from home to our local shop/post office. It's a few hundred yards at most, but along a very busy main road. There is a pavement, although its narrow in places, and at one of the narrowest points it is almost completely over hung by a very tall/thick hedge. So much so that people often have to step into the road to get past. Anyone using a wheelchair or pushing a baby buggy can't get past and have to walk along the road into oncoming traffic. In short, it's a genuine safety hazard. The hedge belongs to a house which has been empty for several months but has recently been sold. What's the best way to proceed here? Knock politely on the door and suggest they cut it back, (no-one in residence at the moment) or do I report it to someone on the council to deal with? Either way, there's going to be accident if it's not restrained pretty soon. Thanks everyone.
