Our mission is to be the champion and regional voice of the resilient lands that are integral to a thriving Bay Area and all people who live here.

Our vision is a Bay Area that is home to healthy lands, healthy people, and healthy communities where we address the impacts of climate change through collaboration. We live in a just and equitable society where we live in relationship with the land that sustains us now and will sustain future generations.

Our Framework for Justice, Equity, and Belonging guides how the Board, staff, and members of TOGETHER Bay Area participate in the organization’s governance, operations, and programs such that we center equity, work for justice, and ensure that everyone belongs.


This coalition stands on the shoulders of the Bay Area Open Space Council. The Council was formed in 1990 by a group of visionary leaders who believed we could achieve more if we worked together. The Council:

  • Helped form the Bay Area Program of the California Coastal Conservancy in 1997 and shape and pass state-wide bond measures which resulted in almost $400 million in funding for 700+ projects and programs in the region.
  • Led the creation of the regional conservation strategy called the Conservation Lands Network, first version 1.0 in 2011, a progress update in 2014, and version 2.0 in 2019.
  • Incubated Transit and Trails, a trip planning app that encourages the use of public transit to get outdoors.
  • Convened the annual Open Space Conference and quarterly Gatherings. See photos.
  • Facilitated relationship-building and information-sharing across the region which resulted in increased capacity, innovation, and impact.
  • And so much more.

The Council went through a significant transition in 2018-2019 which you can read about here and here. Aleta George from the Bay Area Monitor wrote this article in May 2021. Federated Indians of Graton Rancheria, East Bay Regional Park District, Peninsula Open Space Trust, Marin County Parks, Midpeninsula Regional Open Space District, Santa Clara Valley Open Space Authority, and Sonoma Ag and Open Space District provided critical funding for the transition. A 16-member Planning Committee provided visionary leadership and critical thinking at five meetings and in countless emails. And hundreds of Bay Area leaders participated in the planning process through input sessions, surveys, and interviews.

We are grateful to everyone’s contributions to this regional coalition in the past and today.
