GRETNA DOWNTOWN DRAINAGE, PHASE 1
As part of an initiative to address localized flooding and improve pedestrian safety in Historic Downtown Gretna, Dana Brown & Associates (DBA) led the design and construction administration of an urban design project that will reduce flood risk and transform the public space just outside of Gretna City Hall. The project includes renovation of over two acres of the existing neutral ground and adjacent streets, removing approximately 40 percent of existing impervious surfaces. DBA designed green infrastructure facilities including pervious paving, subsurface storage tanks, tree cells, and bioretention cells in street basins, which have the capacity to detain and filter over 14,600 cubic feet of stormwater runoff.
The project showcases the historic Jefferson Memorial Arch, built in 1923 and inscribed with the names of Jefferson Parish war veterans.
