About the Tool

Project Background

The Sea Level Scenario Sketch Planning Tool has been completed over multiple phases since 2012. As sea level projections, tidal datums, and base data change over time and place, this customizable framework of tools facilitates the revision and reassessment of potentially impacted areas and infrastructure. Additionally, as higher resolution data inputs become available, the analysis can change from statewide and regional to more local in scale. The tools developed in this project support higher resolution data inputs and facilitate reproduction of the data outputs (inundation surfaces and affected transportation infrastructure layers).

Phase 1 (2012-13), Version 1 of Sketch Planning Tool released. Researchers from the UF GeoPlan Center developed the Florida Sea Level Scenario Sketch Planning Tool (SLS Sketch Planning Tool) to facilitate identification of transportation infrastructure potentially at risk from projected sea level changes. The purpose of the tool was to visualize various sea level scenarios at future time periods to inform transportation planners and highlight infrastructure for potential avoidance, minimization, or mitigation. The Phase 1 work built upon the research completed under Florida Department of Transportation (FDOT) contract BDK79 977-01, Development of a Methodology for the Assessment of Sea Level Rise Impacts on Florida’s Transportation Modes and Infrastructure (Florida Atlantic University, 2012).

US Army Corps of Engineers (USACE) sea level change projection methodology, as outlined in Engineering Circular EC 1165-2-212, was used in Phase 1 to generate statewide and regional SLR projections (“low/ historic”, “intermediate”, and “high” projections) in 10-year increments from 2040 through 2100. The benefits of this methodology include the use of local data to generate relative SLR projections, projections for multiple scenarios, and the ability to revise the calculations based on the latest available guidance and trends.

Phase 2 (2013-15), the UF GeoPlan Center and FDOT Office of Policy Planning worked with two Metropolitan Regional Planning Organizations (MPOs) to test the tool’s usefulness for planning at the regional scale. Both MPOs were awarded grants through the Federal Highway Administration (FHWA)’s Climate Change Resilience Pilot Program, which has funded partners to assess infrastructure vulnerability to the impacts of sea level changes and extreme weather events, determine adaptation options, and improve resiliency of infrastructure. This opportunity allowed for testing of the SLS Sketch Planning Tool with partners who could benefit from the tools, while providing feedback on usability enhancements.

Phase 3 (2016-17)Version 2 of the Sketch Planning Tool released. SLR scenarios were re-mapped by county, utilizing local tide station data, the best available elevation data, and five SLR projections from NOAA (2012) and USACE (2013). Updated transportation data was analyzed using the newly mapped SLR scenarios, calculating amount and percentage of impact to transportation assets under each SLR scenario. During this phase, a new, modern web map viewer was developed and deployed.

Phase 4 (2019-20)Version 3 of the Sketch Planning Tool released. NOAA 2017 SLR projections were mapped and added to the Sketch Tool. USACE SLR scenarios were re-mapped to reflect updated lidar-based elevation data. Transportation data was added and analyzed for exposure to NOAA 2017 and USACE SLR projections.

Phase 5 (2021-2023)Development of the Resilience Report, a new online screening tool to systematically and rapidly conduct flood vulnerability assessments for transportation projects. The Resilience Report summarizes and displays analyses of current and future flood exposure for a user-specified area of interest (AOI) anywhere in the State of Florida, though the majority of the current data is coastal flooding. The Resilience Report is currently only available to users of the Environmental Screening Tool. Please see the Resilience Report page for access information.

Phase 6 (2024-2025) – Version 4 of the Sketch Planning Tool released. NOAA 2022 SLR projections and inundation models added to the tool. The scenario selector was updated for users to select either the NOAA 2022 SLR projections or SLR by half-foot increment (over mean higher high water). The tool’s base transportation layers (roads, rails, airports, and other infrastructure) and floodplain data was also updated for the exposure analysis.
