Alameda County, California
Alameda County runs from the Oakland and Berkeley waterfront across the hills into the Livermore Valley, holding the East Bay's port, its BART spine, and two of the region's largest job centers. Redevelopment concentrates on transit-oriented infill in Oakland, Fremont's Warm Springs district, and the Tri-Valley office corridor, with hillside seismic constraints, the Alameda Creek watershed, and some of California's most active local growth-control politics governing what gets entitled.
