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.
