LOMA and LOMR-F in Lafourche Parish, Louisiana

The parish experiences flooding from hurricane storm surge, bayou overflow, and coastal subsidence that is lowering land elevations over time. The Morganza-to-the-Gulf levee system provides some protection, but areas outside the levee alignment remain highly exposed to Gulf surge.
