The area around Concord High School attracts a reasonable amount of graffiti, including the concrete barriers down the middle of Crane St, just down the hill from the school. Crane St is a busy road, and the barriers have been put on a particularly nasty corner to stop cars that are speeding down the hill from losing it and crossing into traffic coming the other way around the corner.
The barriers themselves are a target for graffiti. I rang Council about two weeks ago to let them know about it, and when I went past yesterday, all he graffiti had been painted over. I didn't know who to call - whether it was an RTA problem or a Council problem, but the Council has ensured that it has been taken care of.
