New Orleans sits an average of six feet below sea level, with some commercial districts in the Lower Ninth Ward and Lakeview reaching elevations 10 feet below the surrounding water. This geography creates persistent hydrostatic pressure against foundation walls and floor slabs. When pump stations fail or lose power during storms, groundwater rises rapidly into below-grade spaces. Commercial buildings near the Industrial Canal and along the Mississippi River face additional flood risk from storm surge and river flooding. The city's pump-dependent drainage system can become overwhelmed during intense rainfall, causing street flooding that enters ground-floor commercial spaces. These conditions require commercial water damage cleanup protocols that address not just surface water removal but ongoing moisture intrusion from below-grade sources.
