Thank you for submitting this request to the City Attorney's Office. We are in the process of researching this issue and communicating with other city departments to address this issue. I also recommend working with members of the Board of Supervisors to address this ongoing problem. Depending on which part of South Van Ness Avenue you are most concerned about, this probably falls in District 6 (Supervisor Jane Kim) or District 9 (Supervisor David Campos). You can visit the Board of Supervisors' website at www.sfbos.org.
