The matrix was originally developed as part of California’s Lifting the Fog workshop that sought to provide guidance to end users interested in using modeled sea level rise projections in coastal planning. The following agencies/organizations contributed to the development of this online matrix: The Nature Conservancy, NOAA Office for Coastal Management, and Climate Central. See our article posted on the APA Recovery News blog to learn more. The matrix is listed as a resource on the U.S. Climate Resilience Toolkit.
