The Flood Control Act of 1965, Title II of Pub.L. 89–298, was enacted on October 27, 1965, by the 89th Congress and authorized the United States Army Corps of Engineers to design and construct numerous flood control projects including the Lake Pontchartrain and Vicinity, Louisiana Hurricane Protection Project in the New Orleans region of south Louisiana.
The Rivers and Harbors Act of 1965 was also part of Pub.L. 89–298 (Title III).
Sec 201 of the Act authorized the Secretary of the Army, acting through the Chief of Engineers (of the U.S. Army Corps of Engineers) to design and construct any water resource development project, including navigation, flood control, and shore protection if the cost of any single project did not exceed $10 million. Any such project was subject to local cost sharing in the same manner as larger projects.
Sec 208 of the Act authorized the Corps of Engineers to conduct surveys for flood control and allied purposes, to include drainage and channel improvements.
The pre-Katrina Orleans Levee District (OLD), governed by the Orleans Levee Board (OLB), owned considerable assets, mainly real estate, a peculiarity that stems from its history. In the early twentieth century, the OLD reclaimed a portion of Lake Pontchartrain, a 24-mile wide lake north of New Orleans. The OLD developed the land and sold it to raise money to build and improve levees. The Lake Vista, Lake Oaks, Lake Terrace, East and West Lakeshore subdivisions and other property between Robert E. Lee Blvd and Lake Pontchartrain are all examples of these developed properties. The OLD also owned a marina and a small commercial airport on a man-made peninsula created from dredged material in the early 1930s.
In the Flood Control Act of 1965––legislation enacted in response to losses exceeding $1 billion (including multiple levee failures) during Hurricane Betsy––Congress directed the Corps, from then forward, to be responsible for design and construction of the hurricane flood protection system enveloping New Orleans. The Corps was ordered to work in consultation with the OLD which became the local sponsor for the Lake Pontchartrain and Vicinity Hurricane Protection Project.
