Regional Collaboratives

ARCCA represents leading regional collaboratives working to advance adaptation efforts in their own regions while working together to build resilience throughout the state of California. Our network currently represents the North Coast, Capital Region, Sierra Nevada, San Francisco Bay Area, Central Coast, Inland Southern California, Los Angeles County, and San Diego County.

The North Coast Resource Partnership (NCRP) is a long-term, innovative and successful collaboration among Northern California Tribes, counties, and diverse stakeholders. The NCRP region covers over 19,000 square miles – 12% of the California landscape – and includes the Tribal lands and the counties of Del Norte, Humboldt, Trinity, Siskiyou, Modoc, Mendocino and Sonoma. Since 2004, the partnership has engaged in collaborative, integrated planning and project implementation, investing over $67 million in hundreds of projects that benefit the North Coast Region’s communities and watersheds.

The Capital Region Climate Readiness Collaborative (CRCRC) is a multidisciplinary network of local and regional agencies, community-based organizations, businesses, and universities working together to advance climate mitigation and adaptation efforts in their own communities and throughout California’s Capital Region. The CRC region covers the 6-county SACOG region, including the counties of El Dorado, Placer, Sacramento, Sutter, Yolo, and Yuba. The collaborative plays a critical role in the region conducting research, implementing projects, pursuing funding, and providing learning opportunities to build the region’s adaptive capacity and understanding of climate impacts.

The Sierra Climate Adaptation & Mitigation Partnership (Sierra CAMP) is a cross-sector partnership working to promote climate adaptation and mitigation strategies across the Sierra Nevada region. The partnership region spans from Sequoia and Kings Canyon National Parks in the south all the way north to the Oregon border and southern section of the Cascade mountain range, and from the Sierra foothills to the Nevada border. Sierra CAMP also serves as a climate action capacity-building hub for Sierra/Cascade communities and fosters urban-rural connections to build statewide investment in our region’s communities and natural resources.

The Bay Area Climate Adaptation Network (BayCAN) is a collaborative network of local government staff and partners to help the Bay Area region respond effectively and equitably to the impacts of climate change on human health, infrastructure and natural systems. BayCAN covers the 9-county San Francisco Bay Area and primarily exists to facilitate connections, information sharing, and best practices development among local governments; develop opportunities for multi-jurisdictional collaboration and program implementation, and; help secure greater levels of adaptation funding and resources.

The Central Coast Climate Collaborative (4C) is a membership organization fostering a network of local and regional community leaders throughout six Central Coast counties to address climate change mitigation and adaptation. The collaborative involves representatives from local and regional government, business and agriculture, academia, and diverse community groups to share information and best practices, leverage efforts and resources and identify critical issues and needs. 4C aims to engage all communities throughout the region to help ensure a resilient and low-carbon Central Coast prepared for the impacts of climate change.

The Inland Southern California Climate Collaborative (ISC3) is a diverse, cross-sectoral network of agencies, organizations, companies, and institutions, from San Bernardino, Riverside, and Imperial counties, that collaboratively work to advance equitable solutions and seek climate funds to help their communities succeed in the face of climate change. The ISC3 recognizes the importance of joint efforts and works to strengthen local and regional efforts in addressing climate change in the region. Some member benefits include: state policy engagement, connection to funding opportunities, a place for knowledge exchange, and a supportive peer network.

The Los Angeles Regional Collaborative for Climate Action and Sustainability (LARC) is a network of local and regional decision-makers ensuring a sustainable Los Angeles County prepared for the impacts of climate change and it is one of six regional collaboratives in California supporting climate change science, policy and planning efforts across sectors. LARC’s climate mitigation and adaptation work is driven by cutting-edge research on local climate impacts and information management systems. LARC is the sole climate collaborative in the LA region and its network is a cross-section of climate practitioners and decision-makers including academia, cities, LA County, regional agencies, non-profits, and businesses.

The San Diego Regional Climate Collaborative (SDRCC) is a network for public agencies that serves the San Diego region to share expertise, leverage resources, and advance comprehensive solutions to facilitate climate change planning. By partnering with academia, non-profits, and businesses, the collaborative also work to raise the profile of regional leadership. SDRCC supports regional efforts and advances comprehensive solutions to reduce greenhouse gas emissions and prepare for local climate change impacts while building capacity within San Diego regional public agencies through networking, training and partnerships with academic institutions, businesses, and non-profits.
