Leeward Channel Benthic Survey

Summary: Erickson Consulting Engineers, Inc. (ECE) provided coastal engineering and environmental services required to conduct maintenance dredging for the Leeward Channel to restore channel navigation. To facilitate in the design and permitting, biological resources were mapped within the immediate vicinity to identify the quantity and extent of the benthic features.

Key Project Elements:

  • Hydrographic Survey
  • Benthic Resource Survey
  • Hardbottom Species Characterization
  • Quantification of Benthic Cover
  • Pipeline Corridor Siting
  • Resource Avoidance and Minimization of Impacts Assessment
  • Resource Monitoring and Mitigation Plan
The Resource Monitoring and Mitigation Plan was developed to ensure dredging would not occur within 25 ft of any benthic features. Dredge plans minimized impacts to the hardbottom edge.

During and Post-Construction benthic resource monitoring is scheduled for 2014.
