The World Organization of Dredging Associations (WODA) recently held their triennial international conference, which included a gala dinner and awards ceremony where four Environmental Excellence Awards were presented in two categories – Environmental Dredging and Dredging for Coastal Reinforcement. Envirocon was the Prime Contractor for the Project Team that took First Prize for WODA’s Environmental Excellence Award for Environmental Dredging. The winning project was Boeing’s Plant 2 Sediment Remediation and Urban Waterway Restoration at the Duwamish Waterway in Seattle, Washington.
Envirocon provided extensive mechanical precision dredging of 161,000 cubic yards of contaminated sediments from over one-half mile of the Waterway at an active manufacturing facility, and performed shoreline excavation, rehabilitation, and restoration services over five acres of contiguous intertidal wetlands adjacent to this site. The project site is located within an active, navigable channel that flows directly through a major metropolitan city. Environmental sensitivities included protection of fish species, waterfowl, and other wildlife along with coordination with the Muckleshoot tribe during fishing activities.
Several important green initiatives accomplished on this project included the collection treatment of 45M gallons of dredge water which discharged back into the Waterway avoiding off-site disposal. In addition, habitat restoration and preservation was crucial on this project, and to accomplish that, the shorelines were vegetated with marsh and riparian plantings, and large woody debris for additional protection.
The Project Team took on the attitude of “Do it right the first time,” striving to provide innovative solutions to complex problems. Strong leadership and forward thinking methods contributed to the successful restoration of a highly environmentally sensitive industrial waterway. Envirocon is proud to be a member of this team that brought environmental and economic benefits to this community and is honored to be part of the team receiving this prestigious award
