Rising seas threaten coastal populations and infrastructure. This study, conducted in partnership with stakeholders in San Mateo County, California, co-developed nature-based solutions for sea-level rise adaptation. Six guiding principles shaped the planning process, which included vulnerability assessments and the creation of three adaptation scenarios. Scenarios incorporating nature-based solutions yielded up to eight times the benefits of a traditionally engineered approach, including significant habitat gains. The study demonstrates practical tools for assessing the multiple benefits of nature-based solutions in urban estuaries.
