This section prohibited expending funds until the states or levee districts gave assurances that they would maintain all flood-control works after their completion, except controlling and regulating spillway structures, including special relief levees; would agree to accept land turned over to them, and provide without cost to the United States, all rights of way for levee foundations and levees on the main stem of the Mississippi River between Cape Girardeau, Missouri, and the Head of Passes.
Relief from liability A key provision of FCA 1928 was that no liability of any kind would attach to or rest upon the United States for any damage from or by floods or flood waters at any place. The act also stated that, if on any stretch of the banks of the Mississippi River it was impracticable to construct levees (either because such construction is not economically justified or because such construction would unreasonably restrict the flood channel) and previously unaffected lands are subjected to overflow and damage by reason of the construction of levees on the opposite banks of the river, the government has a duty to acquire either ownership or flowage rights over such lands. In January 2008, this liability provision played a controversial role concerning the legal cases resulting from the
levee failures in
New Orleans during the
Hurricane Katrina disaster in 2005. Federal Judge Stanwood Duval, of the US District Court for Eastern Louisiana, held the
US Army Corps of Engineers responsible for defects in the design of the concrete I-wall floodwall constructed in the earthen levees of the 17th Street Canal in the period following
Hurricane Betsy (1965). However, he further stated that the agency could not be held financially liable due to the sovereign immunity provided by this legislation. In April 2010, scholars with the Louisiana State Office of Historic Preservation approved the text for a Historic Plaque for the 17th Street Canal. After receiving permission from city agencies and the Corps of Engineers, the flood protection group Levees.org installed the Plaque at ground zero, on New Orleans city property, in the Lakeview neighborhood. The text of the plaque read as follows: ==Section 4: Flowage Rights==
