While it's by no means plan A or a certainty it appears the A's are exploring as a backup plan moving Cisco Field from it's current planned location at Pacific Commons over to Warm Springs near the planned Warm Springs BART station. As I recall this wouldn't be far from one of the original locations HOK sport was exploring for Alameda County back in the late 90's. Additionally if they did in fact fall back on the Warm Springs "Plan B" the stadium would be decoupled from Wolff's residential project, or so it seems.
