St. Roch Drainage Improvements

The St. Roch 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.



Flooding has damaged numerous homes and businesses within the neighborhood, and ponded water on streets often impacts traffic and requires re-routing. The storm drain system is undersized; approximately half of the streets within the project area have little or no existing drainage infrastructure. The standard approach to fixing urban drainage problems--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 St. 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.
