The coast has always been our first line of defense against hurricanes for southeast Louisiana. Recognizing this, the Lake Pontchartrain Basin Foundation (LPBF) developed the Multiple Lines of Defense Strategy designed to help save our coast. In the simplest terms, this strategy highlighted below shows how natural features of our coast (like barrier islands, marshes, and ridges) compliment manmade features (like levees) to protect the Greater New Orleans area from hurricanes.

Applying this strategy, LPBF looked to its Comprehensive Habitat Management Plan. The CHMP consists of over 100 projects and is the blueprint for restoration of the habitats in the Pontchartrain Basin. The CHMP projects were prioritized choosing the 10 habitat restoration projects that would also provide flood protection for the Greater New Orleans area. These projects became known as the Pontchartrain Coastal Lines of Defense Program.
