The Task Force Once the Report was completed Kiawah leaders began the process of studying its contents and initiating activities to address the challenges outlined in it. The Community Association Finance Committee established an Infrastructure Task Force (Task Force) to study how to manage and improve safety during extraordinary water events. Dave Morely chairs the Task Force. The group recognizes the challenge as two pronged: (1) managing high levels of water on the Island during storms or higher than usual tides or a combination of both of these; and (2) finding ways to prevent excess water from coming onto the Island. The Task Force divided its work into two phases. Phase I involves developing strategies to manage excess water on Kiawah. They are identifying areas where flooding is known to have been especially severe with a view to finding ways to mitigate the impact. The Task Force is also taking an adaptive management approach, working with what is known now and basing recommendations on present conditions. As time passes and we are able to find out whether water levels are in fact rising at higher rates than in the past, we can initiate strategies to address those levels. Once study and analysis of Phase I is completed, the Task Force plans to turn to the challenge of keeping excess water off the Island. The Sea-level Rise Committee The Report is the work product of a special Town subcommittee on flood mitigation and sea-level rise adaption. Kiawah resident John Leffler, who has a PhD in Zoology and Ecology from the University of Georgia, was a member of the subcommittee. Formerly a college professor, upon moving to South Carolina, John worked 10 years for the South Carolina Using a variety of available data, Lucas works to simulate and predict which Kiawah roadways and homes will be impacted by flooding in the future, using models within a Geographic Information System (GIS) environment. GIS tools can easily overlay many layers of information (high- resolution elevations, land use, and flood extent) to create maps and images of the impacts of future flooding events. The final part of this project will be to analyze the flooding data in conjunction with the concerns of residents, Town Council, and other Island entities to develop strategies and ideas that will help Kiawah better prepare for future storms and mitigate the flooding that comes with them. The optimum approach to all these issues is termed “adaptive management,” a system utilized by the United States Department of Defense. Essentially the method uses water levels as predicted over a relatively short period of time and implements changes to address them. Rather than try to plan for 70 years out, steps are taken to address where the water is predicted to be in four or five years. At that time, a new assessment is made to see how closely the prediction matches the actual water level then and how effective any changes have been. As a result of this assessment, a new plan can be formed based on what has been learned over the four- or five-year period. Of paramount importance in all of Lucas’s work is educating the Kiawah community. He says, “Kiawah is a premier community—we want to keep the Island ahead of the game. By being flood ready, it shows that we’re pushing toward becoming a community that can respond quickly and can potentially become a model for other coastal communities.” WINTER/SPRING 2020 • VOLUME 42 11
