Front Yard Floods

Frequent floods blight the poorest neighbourhoods of New Orleans but the residents are fighting back, one yard at a time. Physicist Helen Czerski joins the team behind the Front Yard Initiative as they strive to keep the Big Easy safe and dry, 20 years after the devastation of Hurricane Katrina.When Katrina hit New Orleans in August 2005, the levees broke, 800,000 residents were forced out and 1800 people died. $14bn was spent on concrete and steel to rebuild the defences but the city still floods regularly. This water isn't coming from the Mississippi River sealed behind the new defences, it's coming from the skies. Sudden, violent rainstorms are becoming more frequent and the city's low income districts have notoriously inefficient drainage systems. The water lands on concrete and asphalt and quickly overwhelms the drains.The team behind the Front Yard Initiative is working, block by block, to help residents beat the floods by turning broken concrete into rainwater gardens. Native flowers and cheap, simple engineering are helping to transform neighbourhoods and attract new residents to the battered but beautiful home of jazz, gumbo and Mardi Gras.Image: An example of a front yard made into a rainwater garden, pictured with the owner and team behind front yard initiative.
