Envirosite Provides Environmental Data to Aid
in Hurricane Ida Cleanup Efforts.

 

 

Hurricane Ida made landfall on August 29 at 11:55 am CDT near Port Fourchon, Louisiana, as a Category 4 hurricane with winds around at 160 mph. In addition to high winds, the storm produced over 10 inches of rain in some areas of Louisiana and Mississippi. Power outages were significant and widespread in Louisiana. The National Hurricane Center published Hurricane Ida storm surge maps for the affected states. We combined the National Hurricane Center's Storm Surge data with Envirosite's comprehensive environmental and geospatial data sets to help aid public officials and environmental professionals.

Envirosite's Storm Surge impact analysis indicates the highest number of contaminated sites at risk of flooding in Louisiana are in Terrebonne and LaFourche Counties. For Mississippi, the highest number of contaminated sites at risk are in Harrison and Jackson Counties. For Alabama, the highest number of contaminated sites at risk are in Mobile County.
