In New Orleans, architects and city planners redeveloping neighborhoods flooded by Hurricane Katrina are looking at ways to live with water – not just pumping it out.


For example, the city is converting numerous vacant lots into rain gardens that will absorb, hold and release stormwater slowly after a storm. The idea is to lighten the load on the city’s drainage system during heavy rains.

The pilot project was an 11,000-square-foot site in the Fillmore neighborhood. Called the “Gentilly Rain Garden,” it features native trees, shrubs and other plants that do more than beautify the space.

During storms, the shallow garden temporarily captures and holds rainwater — helping to prevent floods. Then, over the next two days, the water slowly filters down among the plants, into the ground.

David Lessinger, with the New Orleans Redevelopment Authority, says the goal is to create similar gardens throughout the city:

LESSINGER: “One rain garden doesn’t do a lot to mitigate street flooding, but fifty rain gardens interspersed throughout a neighborhood can make a significant impact.”

By planting rain gardens, New Orleans is improving climate resilience and the community’s quality of life.
