One Team: Relevant, Ready, Responsive, Reliable US Army Corps of Engineers 6 Southeast Louisiana Hurricane Protection ADDITIONAL IMPROVEMENTS The Bush Administration on February 16 asked Congress to support an additional $1.46 billion in new funding for improvements to southeast Louisiana’s hurricane protection system. If approved, the proposal would pay for: - Permanent pumps and closures for New Orleans’ three outfall canals. ($530 million) - Two navigable closures that would prevent hurricane surge from entering the Industrial Canal area. ($350 million) - Storm-proofing existing interior drainage pump stations in Jefferson and Orleans Parishes. ($250 million) - Selective armoring for critical portions of the New Orleans levee system. ($170 million) - Incorporation of Plaquemines Parish west bank, non-federal levees into the federal levee system. ($60 million) - Restoration of critical areas of coastal wetlands and ecosystems needed to improve long-term hurricane and storm protection. ($100 million)
