|Regional planners, long dismayed by environmentally destructive suburban sprawl, hope to turn a lot of the Bay Area into something more like San Francisco — walkable, BARTable and very energy efficient. But the “smart growth” renaissance — key to the state’s climate change goals — is facing stiff resistance from cities, and financial pressure from the cash-strapped California state government. Some experts say that on its current path, the plan is too unwieldy to reshape where and how we will live. This special report was produced in collaboration with the CAGE Lab at UC Berkeley’s Geography Department, Earth Island Journal and Bay Nature Magazine.|
Map: The bay’s 50-year boom — population growth, 1960-2010
Among 101 cities, those in periphery grew fastest
Like trees, cities can be thought of as adding growth rings every year. For most cities on this map, the outer ring represents the current population, from 2010 census data. The smallest, inner growth ring was the population in 1960. The largest cities of 1960 — San Francisco and Oakland - have larger inner rings. San Jose is a notable outlier, having swelled to consume the Valley of Heart's Delight. The spacing of the decennial rings allows the reader to understand whether cities' population growth is sudden, like Concord between 1960 and 1970, or gradual, like Pleasanton, denoted by the regular interval between the growth rings. Slow-growing Moraga doesn't show a 1960 ring at all, because it is covered up by the 2010 growth ring.
