The Challenge

Downtowns are frequently separated from their riverfronts with flood walls, levees or other physical barriers. Many of these man-made infrastructural barriers accelerate water flow and limit public access and connectivity.


Lock Nine Park excavates buried canal infrastructure and lays back the levee wall. The raceway now serves pedestrians and cyclists rather than 19th century boats.

The Results

Ground penetrating radar identified that limestone walls of the lock were still in place following the Flood of 1913. Construction of the park is underway.
