Project Update

IDS#1 – Submitted March 2019, Final Approval Received February 2020 – included the project technical approach, digital elevation model and study area characteristics.

IDS#2 – Submitted December 31, 2019, Final Approval Received December 14, 2020 – included the description and process for utilizing numerical storm models to predict coastal flooding and a description of the JPM-OS methodology to develop storm suite that will be used in the analysis.

IDS #3 Section 1 – Submitted May 7, 2021, Final Approval Anticipated November 2021 – ADCIRC and SWAN production runs of the JPM-OS storm suite.

IDS #3 Section 2 – Submitted August 27, 2021, Final Approval July 2022 – included the development of water level and wave statistics from the ADCIRC and SWAN production runs, and the development of the 1% still water elevation surface from the statistical results.

IDS #4 – Submitted December 2, 2022, Final Approval Received April 2023 – included the development of updated transect location maps, detailed wave information including wave setup, runup and overtopping and overland wave propagation.  In addition, erosion analysis was submitted along with a site reconnaissance report the documents the existing coastal structures, characterization of exposure and coastal morphology, and the classification of coastal vegetation and its influence on coastal flooding.

Currently developing flood hazard workmaps for Hancock, Harrison, and Jacksons Counties.  The workmaps are being prepared from the results of engineering analyses performed in IDS#4.  These maps will depict the Special Flood Hazard Area (SFHA), Limit of Moderate Wave Action (LiMWA), and Base Flood Elevations (BFE’s). Once the flood hazard maps are completed, the maps and all the engineering data developed as part of this project will be submitted to FEMA Region IV as a MT-2 Physical Map Revision. This will enable FEMA to review the data and revise the existing FIRMs and FIS reports.

Upcoming Event: Coastal Map Revision Project Presentation at Gulf of Mexico Alliance 2019 All Hands Meeting

SMPDD presents on Coastal Map Revision Project at State of Our Coast

On May 6, 2019, Kristyn Gunter presented on the Mississippi Coastal Map Revision Project at the 2019 State of Our Coast event in Biloxi. The theme of the event was Power of Partnerships, and this meeting brought together state, federal and local government officials, along with academia, non-profit organizations, and businesses to network, collaborate, and leverage opportunities to address issues of local concern. Kristyn’s presentation provided an overview of the Coastal Map Revision Project, discussed how the updated mapping will benefit local communities, and described ways to stay engaged throughout the study process. For more information on the event, please visit the State of Our Coast web page here.
