I'd report it directly to your OPD Problem Solving Officer. That's beat 7X, so
it's Nathaniel Walker, email address:
communitypolicingbeat7@oaklandnet.com
Attach any photos you have to the email.
If you report it directly to your PSO, you can follow up with him on what's being done. As I recall, there's also prostitution activity on Myrtle. That was reported to OPD back on 1/20/13. No idea if OPD went out to look or not.

City of Oakland Public Works Agency referred this issue to OPD, PWA CONTACT service request # 505559.Please contact that agency to follow-up, see “Other Helpful Links” at:
