Climate Change Adaptation


  • Available Here  -  California’s Fourth Climate Change Assessment (Fourth Assessment) includes a suite of technical and regional reports prepared to help inform local and state decision makers about climate change impacts and resilience actions. The jurisdiction of the California Regional Water Quality Control Board, Lahontan Region (Lahontan Water Board) extends from the Oregon border to the northern Mojave Desert, and includes all of California east of the Sierra Nevada crest. Counties in the Lahontan Region include all or portions of the following counties: Modoc, Lassen, Sierra, Nevada, Placer, El Dorado, Alpine, Mono, Inyo, San Bernardino, Kern, and Los Angeles.

    View the following region-specific reports that include climate science, impacts, and adaptation information pertaining to communities and land areas within the Lahontan Water Board’s regional boundary.

  • Sierra Nevada Region Report
    (Modoc, Lassen, Plumas, Sierra, Nevada, Placer, El Dorado, Amador, Calaveras, Alpine, Mono, Tuolumne, Mariposa, Inyo, and the eastern parts of Madera, Fresno, Tulare, and Kern Counties)
  • Inland Deserts Region Report
    (Imperial and the eastern parts of San Bernardino and Riverside Counties)

Funding Opportunities for Climate Adaptation and Resilience Projects

Many of the strategies for local climate adaptation and resilience projects come with a price tag. This section identifies potential funding opportunities that may help the public and the regulated community better position themselves for funding to implement climate change adaptation efforts.

A range of government entities and private foundations offer financial and technical resources to advance local adaptation and mitigation efforts. These funding opportunities are a mix of grants, loans, rebates and tax incentives.  Several entities maintain lists of potential funding sources for climate adaptation projects or investments to date. Some examples are provided below with links to more information:

The Funding Wizard - this is a searchable database of grants, rebates and incentives available to help pay for sustainable projects., It was developed in partnership with the California Strategic Growth Council, CA Natural Resources Agency, U.C. Davis Information Center for the Environment and CalEPA.  This tool lists funding opportunities in categories such as energy, air quality and climate change, transportation, urban development, waste management and water.  The CA Air Resources Board manages the Funding Wizard site and updates it weekly.

U.S. Climate Resilience Toolkit - this is a product of the United States Global Research Program and managed by National Oceanic and Atmospheric Administration (NOAA) Climate Program Office. This tool lists a range of government entities and private foundations that offer financial and technical resources to advance local climate adaptation and mitigation efforts.

California Climate Investments Map - this map illustrates investments at the local and regional level of the State's largest and better known climate and clean energy programs administered by CA Air Resources Board, CA Department of Food and Agriculture, CA Department of Fish and Wildlife, CA Energy Commission, CA Public Utilities Commission, CalRecycle and the CA Strategic Growth Council. Although not all projects in every state program are represented in the map, it serves as a good tool to help shape new funding requests and to avoid duplication in new requests.

Transformative Climate Communities (TCC) Program - The TCC Program is available to fund projects that reduce greenhouse gas (GHG) emissions through the development and implementation of neighborhood-level transformative climate community plans that include multiple, coordinated GHG emissions reduction projects that provide local economic, environmental, and health benefits to disadvantaged communities. Funding for the TCC Program is provided by Greenhouse Gas Reduction Fund (GGRF), an account established to receive Cap-and-Trade auction proceeds. There is $140 million in Implementation Grant funding and approximately $1.5 million in Planning Grant funding for the TCC Program.
