Alliance of Regional Collaboratives for Climate Adaptation (ARCCA)

California’s Alliance of Regional Collaboratives for Climate Adaptation (ARCCA) was formed in early 2012 out of the urgent need to prepare California’s urban centers for the emerging impacts of climate change, including extreme storm events, heatwaves, droughts, and sea level rise. ARCCA currently brings together five regional collaboratives—from San Diego, Los Angeles, the San Francisco Bay Area, Sacramento, and the Sierras —that are coordinating and supporting local climate partners in projects to enhance public health, protect natural systems, build economies, and improve the quality of life in all communities.

ARCCA was formed by California's regional climate adaptation leaders in conjunction with the Governor’s Office of Planning and Research. In each of these five regions, multi-stakeholder collaboratives have been formed — led by the by the Climate Collaborative – San Diego Region, the Los Angeles Regional Collaborative for Climate Action and Sustainability (LARC), the Bay Area Joint Policy Committee, the Capital Regional Climate Readiness Collaborative, and the Sierra Climate Adaptation & Mitigation Partnership. These regional groups include a wide range of public, private, non-profit, and academic institutions.
