Proving Grounds

USACE Buffalo District

The USACE EWN Leadership Team conducted a successful 'proving ground' implementation workshop with the USACE Buffalo District (external link) on 1-3 December 2014.

As a result, three ongoing projects from the broader USACE Buffalo District's EWN portfolio are described below. If you have ideas for an EWN project or for potential EWN partnership opportunities, please contact us at EWN-Buffalo@usace.army.mil.

Cleveland Harbor Green Breakwater

The Cleveland Harbor Breakwater demonstration project involved modifying the design of the standard concrete toe blocks used for breakwater maintenance. The goal was to provide features that could create habitat opportunities for Great Lakes fish and invertebrates that would not otherwise be present. Successful implementation of the project has already led to additional projects on Great Lakes breakwaters. These have considerable potential to be replicated at other federal and non-federal breakwaters.

Braddock Bay Restoration

At Braddock Bay an augmented stone breakwater adds features for the restoration of a barrier beach. The goal of this project is to reduce erosion behind the breakwater where additional restoration measures will increase habitat diversity, extent of emergent wetlands, and ultimately increase the system's suitability for wildlife. The restored barrier beach will help return Braddock Bay to a low energy system; as a result reductions in wetland erosion will be accompanied by natural expansion of submerged aquatic vegetation.

Niagara Falls Storage Site

The Niagara Falls Storage Site (NFSS) is located in Lewiston, NY on a 191-acre, federally owned remnant of the larger Lake Ontario Ordnance Works (LOOW) site, which produced trinitrotoluene (TNT) during World War II. The site was used later by the wartime Manhattan Engineer District (MED) to manage and store radiologic residues derived from the early atomic weapons programs. Radiologic source areas and impacted infrastructure have contaminated soils and groundwater in various areas throughout the site. The demonstration project will document how well phytoremediative components minimize contaminant transport and lessen maintenance costs.
