In the 1930's the Orleans Levee Board completed a levee protection and land development project along Lake Pontchartrain's south shore. A stepped seawall was built and behind it 2000 acres of land were filled in with soil dredged from the lake. The new land stretched to today's Robert E. Lee Blvd. Today the seawall has sunk and 19 foot levees across Lakeshore Dr. protect the city from Lake Pontchartrain storm surge.
