I called the apartment and reported it as soon I was awake enough to be coherent on the phone. The person I talked to seemed concerned. She said that she would increase the patrol around my building (an off-duty police officer lives in the complex), clean the graffiti, and would send out a memo about walking in the proper area.
Since day 1, I have seen tons of people walk in front of and to the side of my apartment. My apartment is a corner apartment on the ground floor. It's situated next to some woods. I have seen people cut through the woods to go to other buildings (and the litter in that area is absolutely terrible). Not a big deal to me until the graffiti situation happened. I specifically told her that I wasn't necessarily blaming any of the people walking through the woods, and I asked that it be addressed in light of the current situation. She said she couldn't do anything unless she saw people doing it, but she would send a memo out to the whole complex (which, a week later, hasn't happened).
I have also had some other issues, such as finding broken beer bottles on my patio at various times (which supposedly can't be addressed unless they know beyond a shadow of a doubt who's doing it), and the fact that my patio floods in the rain. Of course, the water would sooner go to the parking lot that flood my apartment... but I've told them about that several times, and nothing has been done about it.
To their credit, they did clean the graffiti off my window, although it didn't look that hard to do. I think it might have been that spray chalk that people put on cars.
Is there anything else I can do? I took a picture of my window that morning. Packing up and moving isn't really an option right now, although that would be more of an option in early 2011. I don't really feel any safer over here now, and quite frankly, the apartment that I fell in love in 2009 isn't living up to their supposed standards. I don't even know why I pay as much rent as I do. Peace of mind?
Anyway... thanks for any advice.
