City of Oakland Public Works Agency addressed this issue on 02/27/2013, service request # 444740.

Why did this get closed? Is this a cal trans issue or Oakland? The street plates to light posts say city of Oakland.
The graffiti is out of control here. They want folks on Bart to see their crap. Paint the walls dark green that helps to keep it as visual.

Nearly the entire length of 7th was covered with graffiti when I took BART home today. I've never seen it as bad as it is now. This is the first thing people see when they arrive in Oakland, and it looks horrible.
