Located at the confluence of the Mississippi River with the Gulf of Mexico, and just south of Lake Pontchartrain, New Orleans, is surrounded by water in every direction. Moreover, a substantial portion of the city is situated below sea level, creating a "bowl-shaped" topography that is susceptible to flooding. The city currently provides flood and hurricane protection with levees and floodwalls and employs a series of large pumping stations to remove water from the floodplain as quickly as possible during wet weather events. Building a resilient system that addresses physical vulnerabilities such as climate change, subsidence, and sea level rise, and social vulnerabilities such as poverty and income inequality is a difficult challenge that requires a triple bottom line solution. The Blue and Green Corridors project aims to provide an example of a path to success to communities aspiring to resilient and sustainable living in the face of flood risk and natural disasters.
