Adaptation and Resilience in Coastal Mississippi 2018 Interagency Flood Risk Management Training Session Indianapolis, Indiana Mississippi Department of Marine Resources George Shuford Ramseur, Jr. / Director, Office of Restoration and Resiliency [email protected] United States Army Corps of Engineers, Mobile District Tom Smith, PE / Project Manager, Coastal Resiliency Program www.mscip.usace.army.mil MDMR Context The Mississippi Sound Biloxi Mobile New Orleans Ecological & Production Goals Restoration Goals Hancock County, MS (Western Mississippi Coast) Mississippi has lost over 200 acres every year to erosion… for as far back as we can measure. Typical Erosion Scarp in Hancock County Flooding……….. Storm surge / Tropical Riverine / Precipitation Nuisance Tidal / Wind Ecological / Anthropogenic! These factors have shaped our adaptation and responses Broadly described these are: - Structural Restoration of historic landforms (islands, marshes, shorelines) Construction of seawalls, artificial beaches - Non-Structural Buyouts, home fortification & elevation, zoning, codes - Planning Outreach and Partnering Inclusion here does not signify endorsement USACE, Mobile District Context (MDMR Perspective) A Foundational Relationship Mississippi Department of Marine Resources USACE Mobile District Beneficial Use of Dredged Material (BU) Program Support Milestone Collaborations (Round Island) Mississippi Coastal Improvement Program (MsCIP) Current Beneficial Use (BU) Restoration Prograin MDMR and Partners ..... A Milestone - Round Island Cooperative: MDEQ, MDMR, Mobile District, Port of Pascagoula, NFWF & Federal Navigation Funds 220 acre BU project built from 3.3 Million cubic yards (2/3rds of a Superdome) of material dredged during the Pascagoula Ship Channel expansion. This material was originally to be discarded off-shore at an additional cost of $2 million in Federal Navigation finds.

Primary Ecological Function What Else is at Stake? Basic Physical Protection…. Resiliency! The LMACS barrier buffers our coastline from the open Gulf There are always discussions about protection from major storms. However, consider the impact of day to day “offshore” conditions on our future mainland… Also consider: Coastal erosion is steadily moves communities closer to the ocean! Ongoing Adaptation A Master Plan For Mississippi? 1778 Thankyou!.
