Here is the CalTrans URL for maintenance requests, including graffiti:
http://www.dot.ca.gov/hq/maint/msrsubmit/
That wall is extensively covered with graffiti from about the foot of Roble Road eastwards; it's screened by trees for much of its length.

This had to be the most positive experience I've ever had in resolving issues in Oakland. The graffitti was eliminated within 2 weeks of my complaint. Thank you so much!
