Environmental Sensitivity Index
NOAA Office of Response and Restoration
These maps provide a summary of coastal resources that are at risk if an oil spill occurs. This information is helpful for responders and planners looking to identify vulnerable locations, establish protection priorities, and identify cleanup strategies. This collection contains the aggregated Environmental Sensitivity Index (ESI) shoreline, with the following shoreline categories: armored; rocky and steep shorelines; beaches; flats; and vegetated.
