California in practice
As one of the world's largest and most climate-exposed economies, California serves as a keystone for advancing resilience globally. It is a place where local partners, global experts, and RCC's own network of practitioners test and deliver what resilience looks like in practice, generating lessons that travel far beyond the state's borders.
Resilient Cities Catalyst moves high-impact climate resilience projects from plan to place, in close partnership with the historically marginalized and climate-vulnerable communities carrying the greatest share of climate risk.
Background & Framing
Built in 2021 and shaped continually by the needs of California's communities since, RCC’s flagship initiative, California Resilience Partnership (CRP), connects local governments, Tribal nations, nonprofits, philanthropies, and private partners – taking a regional systems approach to resilience building, From greater Los Angeles to San Diego, Sacramento, and the Central Coast, RCC's role is to open doors between partners and the global adaptation expertise, funding, and policy support their projects need, bring global solutions to be contextualized and advanced by on-the-ground expertise of the local partners who know their communities best.
Anchored by the California Resilience Implementation Accelerator, the California Resilience Partnership is now, not only the umbrella for all of RCC’s work in California, but also a bridge to sharing California’s climate leadership globally. California is the keystone to an international strategy for demonstrating what resilience means in practice, and braiding together complementary efforts across California, RCC’s hopes to better inform project development and resilience action, across the nation and beyond.
SolutionsTo meet the urgency of the moment, we act as a two-way throughline for climate solutions across the world – bringing proven practices for California’s most pressing challenges, and uplifting what has worked here locally, to help others more quickly address their own climate impacts.
ImplementationAt the right moment, with the right strategic support, relatively small amounts of money can unstick planning and project concepts, expediting them toward shovel ready, fundable capital projects ready for implementation.
CapacityRCC adds capacity, brings fresh perspectives, and builds the connective tissue that supports local climate leaders who are already working hard to support their communities.
EvidenceResilience value means ensuring we factor in the entire equation - economic and community impacts and future avoided losses have tangible value to our climate decisions today.
Translating Global to Local Solutions
Climate change is accelerating unevenly across the world, striking some places with extreme heat, others with coastal erosion, wildfire, or flooding, often faster than any single community can develop its own solutions from scratch, which makes identifying proven approaches from elsewhere and adapting them locally one of the fastest paths to meaningful adaptation. Coastal erosion, extreme heat, wildfire, and flooding are not unique to California, and cities around the world have already tested engineering approaches, financing models, and governance structures that can save California communities years of trial and error. A sand retention design tested on a reef in Australia may hold lessons for a beach in Southern California. A fire management practice developed over generations by Indigenous communities may offer more relevant guidance for a fire-prone foothill town than a purely technical model. A financing structure used in another country's coastal cities may point to a workable approach for funding adaptation at home. The value of this exchange runs in both directions: California, as one of the world's largest economies and a recognized climate leader, has as much to teach through its own pilots and policy experiments as it has to learn, and building that exchange strengthens the state's ability to raise the profile of its resilience work while giving practitioners access to a far larger body of tested solutions than any one region could develop alone.
RCC's work in California is designed to bring that global perspective home to the communities doing the work. That means running open, international processes that invite outside expertise to compete and collaborate on local challenges, rather than defaulting to a single familiar approach. It means recognizing that many of California's climate risks do not stop at a state or national border, and that the strongest solutions often come from partners working across those same boundaries. It also means looking outward deliberately after a disaster, drawing on recovery strategies and lessons from other regions rather than starting from scratch, and treating historic and Indigenous knowledge as a source of place-based expertise in its own right, not a supplement to more conventional technical models. And it means creating spaces, through international networks and regional convenings, where California's local leaders can compare notes directly with peers facing similar hazards elsewhere in the world. Across each of these efforts, RCC's role is to build the bridges, through competitions, partnerships, and knowledge exchange, that let California communities draw on the widest possible range of tested solutions rather than working in isolation.
Accelerating Resilience Projects Toward Implementation
California is a global leader in resilience project implementation – yet even the state's most established efforts show how much room remains to move faster and more effectively, because the reality is that getting an adaptation project from design to ribbon is genuinely hard. What makes California a leader in resilience and adaptation also leads, often purposefully, to increased implementation hurdles: a permitting system built to protect the environment and center equity, also means longer review timelines before a project can break ground. Funding adds another layer of uncertainty, as many resilience projects depend at least in part on federal dollars that shift or disappear with changes in national funding priorities, leaving local partners with unreliable funding streams that lead to planning and timeline recalibrations. Municipal staff tasked with carrying projects through this process are frequently stretched across far more responsibilities than their teams can reasonably handle, with little time left to chase competitive grants or manage a multi-year implementation timeline. None of this is a failure of will or vision. It reflects how much coordination, funding, and capacity a single project truly requires, and why closing the gap between a finished plan and a built project remains one of the hardest and most urgent challenges in resilience work today.
RCC's role in California centers on closing that gap directly. RCC acts as a connector and facilitator, identifying funding sources and channeling public and philanthropic dollars toward the places and organizations doing the on-the-ground resilience work. Critically, RCC also works directly with municipalities and non-profit organizations to not only provide catalytic funds, but to also ensure the projects can properly leverage the smaller dollar amounts to advance projects toward implementation, unlocking larger capital sources. RCC brings its global network of experience and technical know-how to support California’s existing infrastructure of partners, ensuring their local experience remains the center of the work – acting as the connective tissue that ensures a community's plan becomes a project that gets built.
Building Governance Capacity to Institutionalize Resilience
A coastal community managing erosion and flooding faces different priorities than an inland community facing extreme heat or drought, and a fire-prone foothill county needs different tools and resources than a flood-prone valley. A rural county with far fewer municipal staff can face the same climate hazards as a well-resourced metro region, but without the funding and manpower for implementation, or knowledge and experience that bigger cities have to navigate a competitive grant cycle or a multi-year permitting process. Local context varies across a state as large as California, but the underlying challenge does not: whether it is at the community, city, county, or regional level, some combination of local organizations that seek to address the greatest hazards and risks already exist. Successful local resilience building does not require starting from scratch, but instead relies on how investment and support can strengthen and capacitate the existing infrastructure of actors toward better resilience and adaptation practice.
RCC's work specifically targets that gap, connecting local governments, nonprofits, and community organizations to the funding, technical expertise, and peer networks that build lasting capacity rather than one-off support. Rather than treating each community's needs as a separate problem to solve from the beginning, RCC works to pair seed funding with direct, hands-on technical assistance, so that community-led partners get support suited to the specific hazard and capacity gap they face rather than a generic solution. That same approach extends to bringing together communities of different sizes and resource levels so that smaller cities and counties gain access to the same expertise and peer knowledge that larger, better-resourced places have built up over time. And because one-time grants rarely solve a long-term capacity gap, RCC also works to help communities build more durable, local sources of funding and institutional knowledge, reducing how much capacity has to be rebuilt from scratch with every new grant cycle or staff transition. Across each effort, RCC's role is to bring outside expertise and funding connections to the table while strengthening the local knowledge and institutions that will carry resilience work forward long after any single project is complete.
Quantifying Resilience Value & Impact to Unlock Investment
Quantifying resilience value and impact means putting a number on what a community stands to lose from a climate hazard, and what it stands to gain from investing in protection against it. For decades, the case for resilience projects has often rested on hazard maps and risk projections alone, which can be hard to translate into budget decisions or funding applications. Preventive investment is a particularly hard sell because the payoff is a disaster that never happens, an outcome with no headline and no visible constituency, while the price tag for rebuilding after a fire, flood, or storm is easy to see and easy to fund after the fact. A community facing extreme heat can show the projected rise in emergency room visits and lost workdays if cooling infrastructure is delayed. A coastal city losing beach width to erosion and sea level rise can show the tourism revenue, tax base, and property value tied to that shoreline. A neighborhood at flood risk can show the cost of repeated infrastructure damage against the cost of upgrading stormwater systems now. In each case, quantification turns a hazard into a number decision-makers can weigh, compare, and act on, and it helps ensure that the communities carrying the greatest climate risk, often those with the fewest resources to make their case, are not also the ones left out of funding decisions.
This work sits at the center of RCC's approach in California. Rather than treating quantification as a one-time report, RCC works to build the economic case for resilience directly into a project's funding strategy, translating the value of a healthy beach, a cooler neighborhood, or a functioning watershed into terms that funders and elected officials can act on. That same lens extends to the systems meant to fund resilience work in the first place, examining how well existing grant programs and monitoring practices actually account for the outcomes they are meant to support, and where gaps in data or evaluation leave good projects unable to make their case. It also shapes how RCC thinks about longer-term investment, since durable local funding tools depend on being able to show funders and residents alike exactly what is being protected and what that protection is worth. Across each effort, RCC's role is to give California communities the evidence base they need to compete for funding, plan with confidence, and make the case for resilience investment on equal footing with other public priorities.
