The City of New Orleans

Mayor Mitchell J. Landrieu

St. Roch Drainage Improvements & Green Infrastructure


The Saint Roch neighborhood project area consists of the 26 city block section bounded by N. Roberston St. to the north, Franklin Ave. to the east, St. Claude Ave. to the south and Elysian Fields Ave. to the West. The neighborhood experiences chronic flooding from even relatively small storms, with more severe flooding associated with larger storm events. The flooding has damaged numerous homes and businesses within the neighborhood and ponded water on streets often necessitates the rerouting of traffic. The storm drain system is undersized and approximately half of the streets within the project area have little or no existing drainage infrastructure. The standard approach to fixing urban drainage problems, that of installing more drainage structure pipes adequately sized to convey stormflows, will not work in St. Roch, as there is nowhere for the water to go during storms.

For the neighborhood of Saint Roch, the project represents the opportunity to realize renewed and transformative streets with underground stormwater detention and “at the surface” green infrastructure which will greatly improve streetscape aesthetics and the quality of life in the neighborhood.
