Coastal Assessments and Risk Forecasts from Hurricane Ida

By Supplemental Appropriations for Disaster Recovery Activities

In FY 2022, USGS received disaster supplement funds (Public Law 117-43) for the following activities:

Hurricane/coastal assessment and risk: tasks and benefits 2022

  • As Hurricane Ida made landfall in the Gulf of Mexico, Louisiana’s protective barrier islands and marshes deteriorated and shifted landward. After the storm moved inland, it stalled over New York City, where stormwater management infrastructure was overwhelmed and resulted in extensive flooding of streets, buildings, subways, and other public spaces.
  • These local and immediate effects complicate the efforts of community and public land managers responsible for protection, planning development, and recovery efforts.
  • Funding will be used to update data and analysis in Louisiana and New York to accurately forecast flooding and erosion hazards, improving future storm-response operations, and to address resilience, including areas with environmental justice concerns.

National Assessment of Hurricane-Induced Coastal Erosion Hazards

These datasets contain information on the probabilities of hurricane-induced erosion (collision, inundation, and overwash) for each 1-km section of the United States sandy open-ocean coastline for category 1-5 hurricanes. The analysis is based on a storm-impact scaling model (Sallenger, 2000; https://www.jstor.org/stable/4300099) that uses observations of beach morphology combined with sophisticat
