Envirosite Provides Environmental Data to
Aid in Hurricane Laura Cleanup Efforts.
Hurricane Laura made landfall on August 27 at 1 am CDT near Cameron, Louisiana, as a Category 4 hurricane with winds raging at 150 mph. The National Hurricane Center published Hurricane Laura storm surge maps for Louisiana and Texas. During catastrophic weather events, we believe it is our civic duty to provide free maps on the impacted areas. We combined the National Hurricane Center's Storm Surge data with Envirosite's extensive environmental and geospatial data sets to help aid public officials and environmental professionals.
The Storm Surge impact analysis indicates the highest number of contaminated sites at risk of flooding in Louisiana were in Calcasieu, Cameron, Jefferson Davis, Terrebonne, and Vermilion Parishes. For Texas, the highest number of contaminated sites at risk were in Orange and Jefferson Counties.
