What can we do to stop this! It happens every week. :(

I live on Ivar and am sick and tired of assholes spray painting the tunnel on Ivar. Its also a popular drop off of unwanted furniture and trash. What can we do? Is it possible to put in a camera somewhere? Put up no dumping signs? I don't even know who cleans/paints over this crap. Vine Street also gets dumped on - the people who park there on the weekends to go down to the clubs, dump beer cans, bottles, trash, etc. I wish we had a neighborhood cleanup crew and/or security. Whatever happened to the parking stickers?
