Plan Bay Area

Plan Bay Area is an unprecedented regional strategy for creating sustainable communities throughout the region. Greenbelt Alliance was the leading advocate for Plan Bay Area from day one, spearheading support for its adoption in 2013 as well as its first update in 2017 to become Plan Bay Area 2040.

The final adopted Plan Bay Area 2040 is a blueprint for directing all growth in the Bay Area to occur within our existing urban footprint, instead of sprawling onto the natural and agricultural lands of our greenbelt. Here are some highlights from the plan:

  • No sprawl development for 25 years—100% of new growth within existing urban growth boundaries
  • Nearly 80% of new homes and more than half of all new jobs near transit
  • An “Action Plan” chapter with local and regional solutions for our housing affordability, economic development, and climate resilience challenges

Plan Bay Area is updated every four years.

As the leading organization on how the Bay Area grows, we are working make Plan Bay Area’s vision a reality.

Plan Bay Area 2040 Adopted

You Can Help

Thank you to all those who joined us on this journey over the last four years. Now that Plan Bay Area 2040 has been adopted, it’s time to roll up our sleeves and get to work to bring the plan’s smart growth goals to fruition. In particular, there’s much to be done to carry out the important regional strategies outlined in the Action Plan and to help our cities and towns follow through on the plan’s vision for the right development in the right places.

We’re already hard at work on both those fronts. For example, we’re serving on a new regional task force, called CASA, to find sustainable strategies for housing affordability. And we’re working on the ground in places like SunnyvaleAntioch, and Solano County.

Thank you for your support in helping this win, and for making our work, possible. Together, we will show the nation how a bold vision for a better future can become reality—but it won’t be easy. It requires dedicated effort in every city and town across the region. Help us make the Bay Area more affordable and sustainable by standing up for good development inside of our cities and towns.

Lend your support for these Greenbelt Alliance endorsed developments. Tell local politicians that you support smart growth.
