Climate Change Vulnerability Assessment
In 2016, the Sarasota Bay Estuary Program received funding from the Climate Ready Estuaries program of the Environmental Protection Agency to conduct a risk-based assessment of its Comprehensive Conservation and Management Plan (CCMP). The goal of the assessment is to identify goals within the CCMP that may be vulnerable to climate change impacts such as sea level rise, ocean acidification, changing air and water temperatures, and changes in precipitation patterns.
In November 2016, the SBEP held a joint meeting with the Science and Environment Council of Southwest Florida to gain stakeholder input on the potential sensitivities of CCMP goals to climate change impacts. The 55 meeting attendees identified over 120 potential vulnerabilities in six CCMP goals spanning the SBEP mission to restore and protect Sarasota Bay. Input from this meeting will be incorporated into the climate vulnerability assessment, which is slated for completion in fall 2017. Read the meeting report here.
Sea Level Rise
SBEP and its partners are aware of the potential long term impact of rising sea levels along the coast. Planning for changes to shorelines and the larger impact on the community will become increasingly important in the decades ahead. To support future planning, SBEP has created a Sea Level Rise web map tool that shows various scenarios based on different levels of water due to sea level increases and surges of water from occassional storms.
This pilot project is a collaborative effort of SBEP and Mote Marine Laboratory, with funding from the U.S. Environmental Protection Agency Climate Ready Estuaries Program. The areas shaded in blue show lands vulnerable to sea-level rise along the Sarasota Bay Estuary. The visualization tool shows an approximation of potential flooding in Sarasota and Manatee Counties, but not exact locations.
The analysis is based on the mean higher high water level obtained from LiDAR elevation imagery. The LiDAR data has a vertical accuracy of 0.60 feet (at a 95% confidence interval). The LiDAR data does not cover depth of water columns. All cells in the DEM grid below sea-level rise thresholds were designated as inundated regardless of hydrologic connectivity. The water levels shown are the flooding above the mean high tide level, but do not take into account the possibility of erosion, land subsidence, sediment accretion, or future construction. To display the potential flooding in the event of a hurricane driven storm surge, the map also illustrates (in shades of magenta) the extent of a Hurricane Charley-level storm surge for each sea level increase.
