The Nevada Department of Transportation has classified two bridges along Interstate 80 as scour critical, and has contracted Granite Construction on a Construction Manager at Risk (CMAR) basis to design and implement a scour protection plan. Balance worked in concert with Wood Rodgers to fulfill environmental permitting requirements for the project, including development of a riverbed restoration plan. Balance approached the design through detailed geomorphic mapping of the reach to document the channel conditions prior to disturbing the riverbed to install the scour protection features. As part of the mapping effort Balance worked with Trout Unlimited to identify the key aquatic habitat features that should be rebuilt following construction. The final design proposes to reassemble the channel to closely resemble existing conditions so as to not disrupt important geomorphic processes or degrade habitat quality. Balance will provide construction oversight upon implementation of the project in summer 2018.
