Environmental challenges arose during our design improvements to a Wisconsin highway being reconstructed through a community and requiring bridge replacements over two creeks. The project area included numerous aging hazardous material sites, three properties eligible for the National Register, a significant archaeological site, and state-threatened species. We successfully navigated several environmental processes to deal with these constraints. We collaborated with resource agencies to develop mitigation for 4(f) and 6(f) impacts to public lands surrounding Black Earth Creek, a Class I trout stream. Four residential and three commercial properties were relocated to accommodate the expansion efforts.
We performed a full complement of services that ranged from survey, alternatives analysis, environmental documentation, noise analysis, wetland delineation, preliminary and final design through to traffic analysis, transportation project plats and construction staging.
