Mark Ellard to Present on Coastal Resiliency at the 33rd Annual National Conference on Beach Preservation Technology

Mark Ellard, P.E., CFM, D.WRE (Florida) will present "Future 100 Year Flood Map for Coastal Resiliency in Broward County" at the 33rd Annual National Conference on Beach Preservation Technology at the Hyatt Sarasota in Sarasota, Florida at 11:20 a.m. on February 7.

Mark's co-presenter is Carolina Maran, Ph.D., P.E., Environmental Planning and Community Resilience Division, Broward County Environmental Protection and Growth Management Department, Fort Lauderdale, Florida.

Mark is a Senior Principal Water Resources and Environmental Engineer based in Florida with more than 25 years of experience in diverse watershed management, water quality assessment, and stormwater design projects.

The Tech Conference Planning Committee selected more than 60 presentations that reflect the most current and relevant topics affecting coastal resources and environment. Attendees will have the opportunity to meet coastal engineers, scientists, academics, students, and government officials, and learn about their recent innovations and research.

The Conference Objectives are to present the latest in beach preservation technology, coastal research, and real-world practice; provide a forum to convey technical findings from the scientific and engineering community to government officials and coastal program managers who make the decisions on coastal projects and policies; and to offer 16.75 hours of professional development units to help with educational certifications.

The Florida Shore & Beach Preservation Association was organized in 1957 at a meeting of 37 local government and university leaders concerned about the growing problem of beach erosion that had virtually destroyed important resort beaches such as Miami Beach. They recognized that erosion was a statewide problem that couldn't be handled by individual cities and counties alone.



As part of Broward County's efforts to build coastal resilience and address the impacts of climate change, especially sea level rise, the Broward County Board of County Commissioners approved the creation of a Future Conditions Map Series in the Broward County Code of Ordinances. The first map of the series – Future Conditions Average Wet Season Groundwater Elevation Map – was approved in July 2017 and establishes antecedent conditions for application in surface water permitting of all major redevelopment and new development projects. The map ensures drainage systems will function under conditions of additional sea level rise and more intense rainfall predicted through 2060 - 2069, decreasing future flood risk. The second map of the series – Future Conditions 100-year Flood Elevation Map – currently under development – will establish minimum finish flood elevations, under the same 2060-2069 seal level rise scenario, and a selected future 100-year rainfall event.

The presentation will discuss the leveraging of a County-wide integrated hydrological, hydraulic, and groundwater flow model to develop the future conditions 100-year flood map product. Stakeholder contributions to the model development, coastal considerations, and model calibration will be summarized. The efforts to develop extreme future rainfall scenarios for the study will be discussed including the expanded analysis of a varied set of downscaled rainfall datasets, including CORDEX, COAPS, BCCA, LOCA, Raw GCMs and Jupiter WRF, with the goal of reducing associated uncertainties in determining future rainfall through a super-ensemble approach.

This project breaks new ground in coastal resiliency by addressing future risk head on. The results of the study may provide guidelines for other coastal communities to likewise advance technical approaches to support addressing future uncertainty and implementing modernized design standards.
