During the planning process, Tybee Island went from a class 7 to 5 in Community Rating System, enabling savings of $3 million on flood insurance for property owners on the island.įunded by the NOAA’s National Sea Grant College Program, the City of Tybee Island Sea Level Rise Adaptation Plan has emerged as a model for other coastal communities across the country.Cardinal Drive across the street from Herb Creek on Isle of Hope on Friday morning, Nov. The Tybee Island Sea Level Rise Adaptation Plan directly impacted the economy of Tybee Island by helping to improve the City’s rating under FEMA’s Community Rating System. This research has also resulted in tangible savings. “This plan analyzes how sea-level rise could disrupt economic activities on the island and whether proposed adaptation actions would pay off in the end.”ĭuring the planning process, outreach efforts and public town hall meetings engaged more than 4,000 people, helping to raise awareness of the city's vulnerabilities and set planning priorities. “Both in leadership and risk, Tybee Island is at the front lines of sea-level rise adaptation,” said Jason Evans, an assistant professor of environmental science, now at Stetson University.
Those events cut the island off from the mainland, proving to not only be a safety and evacuation concern, but an economic one, as well.

The plan recommends steps to modernize and replace portions of U.S. In April 2016, Tybee Island City Council voted unanimously to accept a plan addressing risks that the island faces from sea level rise over the next 50 years. Drawing on visualizations from the Sea Level Rise Viewer, interviews with stakeholders, and public meetings, the city is now prioritizing its action plan and outlining steps to prepare for a future of higher tides and rising seas. 80 causeway (the only road to and from the island), retrofitting stormwater drainage systems, and stabilizing shorelines in order to block high water from storm surge or extreme high tides. Plans included major improvements to the U.S. Together, Evans and Tybee Island officials, utilizing funding from the National Sea Grant Community Climate Adaptation Initiative, outlined six plans for adapting to future sea level rise.

This encouraged city officials-and the population of Tybee Island-to investigate longer-term solutions for critical infrastructure, housing, and facilities. Using the tool, Evans helped identify the areas already affected by flooding and showed how those problems could worsen with continued sea level rise. One of the key tools in this process was the Sea Level Rise Viewer. Evans worked with the city to help identify areas were most vulnerable to projected sea level rise. Jason Evans, an environmental sustainability analyst with the University of Georgia and Georgia Sea Grant. To develop a plan that could prepare their island for the future, city officials reached out to Dr. In order to prepare for and adapt to rising waters, Tybee Island officials knew they needed a plan.
