And this is in the midst of another epic drought. These properties will cover even more ground with concrete, worsening water loss and wiping out trees.

But did the California government target disused COMMERCIAL properties for redevelopment into high-density, walkable residences? NOPE. They didn't even try that before voting to destroy existing residential neighborhoods.
