Improving Resilience to Future Extreme Precipitation Events

Jupiter’s capabilities in downscaling and data analysis, along with its climate science expertise, are extremely valuable for the project.

Broward County, FL – January 16, 2020
Florida’s second-most-densely populated county, with almost two million residents—is vulnerable to both sea-level rise and the increased frequency of extreme rain events. GeoSyntec Consultants engaged Jupiter as a subcontractor to help Broward develop its Future Conditions 100-Year Flood Elevation Maps. The maps will establish a baseline for future resiliency for the county’s buildings and infrastructure and help prepare it for projected sea-level rise and climate-change-induced hydrological changes.

Broward will use the maps and the underlying data to (1) establish new regulatory criteria for setting finished floor elevations for new construction and major redevelopment, and (2) guide both siting and design of critical infrastructure. Jupiter leveraged its unique capabilities in climate science, downscaling, and data analytics to support the county in developing a standardized approach for incorporating extreme precipitation into the analysis of future 100-year flood elevations. The results are expected to be integrated into county building codes, helping to reduce flood risk, lower flood insurance costs, and increase the sustainability of structures over their lifespan.

Validating Data—and Putting it to Work
Broward County also wanted to understand how Jupiter’s downscaling results compare to other publicly available datasets. It asked Jupiter to analyze downscaled data from the Locally Constructed Analogs (LOCA) dataset and Jupiter’s Weather Research and Forecasting model dataset for current and future (~2065) extreme rainfall for the South Florida region. Jupiter validated that the forward-looking, fine-resolution projections created by its downscaling processes reproduced historical and current extreme rainfall when compared to NOAA Atlas-14 data and then provided future extreme rainfall projections from downscaled data.

In addition, Jupiter provided expert guidance for using this climate change information to develop an ensemble-based standard for incorporating downscaled extreme precipitation projections into its Future Conditions 100-Year Flood Maps.

“Jupiter’s capabilities in downscaling and data analysis, along with its climate science expertise, are extremely valuable for the project,” said Carolina Maran, Water Resources Manager and Project Manager of Broward County. “Jupiter provides added confidence to the county’s process for developing a standardized approach for incorporating extreme precipitation projections into our strategic planning.”
