Maybe Berkeley should also try to address the other unending issues that they keep up to prevent any meaningful change, if they really mean it:
-- Endless and convoluted environmental + city approvals processes that corrupt any transparent application for development and favor those who have money to navigate it
-- Picking and choosing special interest / special case neighborhoods or people to try to protect, to the detriment of everyone else wanting to live there
-- Rent control
-- The extremely backwards property tax policies that favor existing landowners over anyone new, young, poor (though this admittedly is California's problem, not just one city or county) and make everything else attempted bandaids -- and misguided bandaids, at that -- to fix the system.
