Given San Francisco’s Bay Area population growth projections from seven to nine million people by 2040 and climate change projections, current challenges such as flood risk, accessibility to safe drinking water, or nature protection might be exacerbated in the near future. With the goal to integrate flood risk management practices, climate change adaptation and habitat protection, different initiatives related to Nature-based Solutions are now emerging at different scales in the San Francisco Bay Area. One example at a large scale is the Bay Area Greenbelt promoted by the Greenbelt Alliance. The San Francisco Bay Area has access to a 3.6 million-acre “greenbelt” that provides clean air and water, productive farmlands, and nearby natural areas to experience the power of nature. The Greenbelt Alliance works to protect these lands through sustainable land-use policies. An example at a urban scale is the Urban Greening Bay Area initiative, a collaborative effort to re-envision Bay Area urban landscapes with widespread green infrastructure to address climate change impacts, infiltrate or capture stormwater and pollutants near their sources, and in turn, promote improved water quality in San Francisco Bay. Nature-based Solutions is seen as a multi-benefit solution that addresses stormwater quality and quantity concerns, while providing myriad ancillary benefits. Finally, a regional planning example is Adapting to Rising Tides , an initiative that creates a place for local governments to find planning guidance, tools and information that have been developed, tested and refined by the Adapting to Rising Tides Program to address the specific challenges of climate change incorporating more sustainable natural solutions to reduce the impacts of coastal flooding.
