Extensive erosion and coral losses result in increased immediate and long-term hazards to shorelines that include densely populated regions. These hazards put critical infrastructure at risk to future flooding and erosion and may cause economic losses. The USGS Coastal and Marine Hazards Resources Program (CMHRP) is assessing hurricane-induced coastal erosion along the southeast US coastline and implications for vulnerability to future storms. Purpose: Shoreline positions were compiled prior to and following Hurricane Irma along the sandy shorelines of the Gulf of Mexico and Atlantic coasts of Florida and the coast of Georgia. Shoreline positions from the mid-1800s through 2018 were used to update the shoreline change rates for Florida and Georgia using the Digital Shoreline Analysis System (DSAS) software. The shoreline positions and updated shoreline change rates provide actionable information to homeowners, coastal communities, and managers of public and private properties to improve resiliency for long-term hazards. This dataset includes a reference baseline used by the Digital Shoreline Analysis System (DSAS) to calculate rate-of-change statistics for the Florida east coast (FLec) (border with GA to Key Biscayne) coastal region. The baseline layer serves as the starting point for orthogonally-oriented transects generated by the DSAS application. The transects intersect each shoreline and establish measurement points used to calculate shoreline change rates.

It does not correspond to any real-world feature. Lineage: Process_Step: Process_Description: A baseline was constructed with respect to the time series of shoreline positions using standard editing tools in Esri's ArcMap v10.7. The offshore baseline was positioned to conform to the overall orientation of the shorelines alongshore. This was done so that the transects, which are generated by the Digital Shoreline Analysis System from the baseline, would intersect roughly perpendicular to the general trend of the shorelines.
