Description

Tampa International Airport’s Resiliency Assessment identified a need to update the Airport’s storm surge inundation data to more accurately determine risks and vulnerabilities posed by storm surge from the waters of Tampa Bay. The last evaluation of storm surge inundation at TPA was completed in 2005. The 2005 evaluation considered the Storm Tide Atlas for Hillsborough, Manatee, Pasco, and Pinellas Counties developed by the Tampa Bay Regional Planning Council as well as the Tampa Bay Region Hurricane Evacuation Study of 2000 and evaluated the effects of new surge heights with respect to current topography and infrastructure at TPA, while specifically focusing on inundation due to storm surge from tropical storms and hurricanes. In 2009 the National Oceanic and Atmospheric Administration (NOAA) updated the Sea, Lake, and Overland Surges form Hurricanes (SLOSH) model, and in 2010 the Tampa Bay Regional Planning Council updated the Statewide Regional Evacuation Study and Storm Tide Atlas. The updated SLOSH model reflects improvements such as higher resolution basin data and grid configurations as well as the data from storms that have taken place in the Gulf since 2000. The improvements were utilized to develop additional hypothetical storms when creating maximum potential storm surge values. Additionally, since 2005, TPA has undergone numerous construction projects, which have changed the topographical features and related drainage systems at the airport. As a result, the Authority needed to update the hurricane surge evaluation last performed in 2005 for TPA. The update incorporated the latest available storm surge data and applied it to the current topographic features and current drainage systems at TPA. The analysis also included the evaluation of the effects of sea level rise on surge elevations at TPA for the year 2050 and 2100 for Category 3, 4, & 5 hurricanes at high tide. Our presentation would use the TPA Airport SLOSH and Resiliency project as a case study to explore NOAA SLOSH analysis and climate change. Diving into what data is available, and how this can be utilized to evaluate storm surge inundation and more accurately determine risks and vulnerabilities posed.
