Napa River dikes were overtopped, resulting in landside erosional damage. The critical nature of the structure required the U.S. Army Corps of Engineers Sacramento District, to implement risk reduction techniques, such as levee armoring.


The Corps selected Propex to rapidly deploy the ARMORMAX® 75 system to immediately protect the City of Napa with a sustainable soft armoring solution that is vital to flood protection efforts.
