The headline makes it sound broader than it is. Rather than "CA Cities", it's actually "will eliminate the zoning ordinances of the vast majority of cities throughout the Bay Area". Still pretty broad, of course.
Edit:
RHNA: regional housing needs allocation
SANDAG: San Diego Association of Governments
SCAG: Southern California Association of Governments
ABAG: Association of Bay Area Governments
AMBAG: Association of Monterey Bay Area Governments(We usually do this ourselves, but I find the details here a bit disorienting and don't have time to concentrate on it)
This is a confusing situation! confusing to me at least.
