I suggest you immediately file a complaint with the district attorney. They intend to violate 66.0409. Just like the DA/police department investigates Open Meetings law violations, file a complaint with the DA and do it now! Get your fellow OC supporters to go down to the DA's office and file a complaint as well.
If the DA refuses to investigate, flood him/her with inquiries as to why, andfilecomplaints against the DA with both the AG's office (refusing to investigate crimes) and the state bar.
