Critical Facilities Flood Exposure Tool

NOAA Coastal Services Center

Features

  • Overlays critical facilities in a county or municipality with FEMA’s 1% annual chance flood zone
  • Provides a report of critical facilities and the number of road miles in the flood zone

Overview

The Critical Facilities Flood Exposure Tool provides an initial assessment of a community’s critical facilities and roads that lie within the 1% annual chance flood zone established by the Federal Emergency Management Agency (FEMA). The tool helps coastal managers quickly learn which facilities may be at risk—providing information that can be used to increase flood risk awareness or to inform a more detailed analysis. The critical facilities tool was initially created to assist Mississippi/Alabama Sea Grant in conducting its “Coastal Resiliency Index: A Community Self-Assessment” workshops and has been expanded nationally.
