Southeast Florida Compact Analyzes Sea Level Rise Risk

Unified Sea Level Rise Projection(37 pp, 538 K, About PDF)ExitSoutheast Florida, with a large population located at low elevation, is among the most vulnerable regions of the country to climate change. The region is comprised of four counties (Monroe, Miami-Dade, Broward, and Palm Beach) that share similar geographic traits and coastal vulnerabilities to sea level rise. Rather than separately attempting to identify climate projections and vulnerabilities, leaders of these counties recognized an opportunity to collaborate and identify climate impacts and vulnerabilities across the region.

A first step was to standardize projections and map sea level inundation. This single region-wide effort brought core stakeholders from counties, regional water management organizations, local universities and federal agencies together to create a regional vulnerability assessment of inundation and flooding. The resulting regional map identified vulnerable infrastructure, including drinking water and wastewater utilities from across the region, and was instrumental in informing development of the South Florida Regional Climate Action Plan. The Regional Action Plan "A Region Responds to a Changing Climate" provides a comprehensive set of recommendations for local governments, focusing on sectors such as transportation, natural resource management, emergency management, and the water sector among others. The Regional Action Plan recommendations on water supply, management and infrastructure protection efforts has since been supplemented by the implementation guidance on "Integrating Climate Change & Water Supply Planning In Southeast Florida". The Compact counties, municipalities, and other organization continue to collaborate on updates to climate projections, including a recent 2015 Sea Level Rise Update, and other common adaptation resources.

A community doesn’t always have to develop new information, for an example of a community that used existing sources of information to guide decision making, see Anacortes. Many communities in the southeast may have to deal with challenges to their source water – whether it is saltwater intrusion, sea level rise, or threats to the facility infrastructure – to learn how a utility is adapting to ensure source water availability, view Tampa Bay Water.
