Project Spotlights:

Navy Yard Dry Stack Marina-Water-Environment-Consultants-background
North Charleston, SC

Navy Yard Dry Stack Marina

• WEC was contracted by T.Y. Lin to evaluate design conditions for a proposed dry stack marina docking facility, complete with a floating wave attenuator, fixed pier, drop well and floating docks.

• The study incorporated extensive field measurements for tidal currents and vessel wave heights. WEC used the 2D SWAN model to establish extreme wave conditions at the site for a variety of storm scenarios and return periods. The project also included an assessment of sedimentation rates at the proposed dock facility to estimate future dredge maintenance needs.

James Island Yacht Club-Water-Environment-Consultants
James Island, SC

James Island Yacht Club

• Jon Guerry Taylor & Associates retained WEC to assess the extreme wind, wave, and water level conditions at the James Island Yacht Club to support the design of a new wave attenuator and dock system. WEC developed a 2D SWAN model to simulate the wave climate during a multitude of storm scenarios and return period events.
Lyman-Morse Marina-Morse-Water-Environment-Consultants
Camden, ME

Lyman-Morse Marina

• WEC conducted an extreme conditions assessment for Harbor Engineering, LLC to support the expansion design for the Lyman-Morse marina.
• The study defined storm surge, wind, and wave conditions for various return periods to develop appropriate performance and survivability design criteria.
Charleston Harbor Navigation Channel Deepening Study -Water-Environment-Consultants-background
Charleston, SC

Charleston Harbor Navigation Channel Deepening Study

• Under contract with the South Carolina State Ports Authority (SCSPA), WEC evaluated the potential environmental effects from deepening and widening the federal navigation channel within rivers that have a TMDL for dissolved oxygen.

• Services included numerical modeling with a 3D application of the EFDC model to assess hydrodynamics, sedimentation, and water quality effects of the proposed deepening. The results were incorporated into the Feasibility Study and Environmental Impact Statement and saved on the order of $100M in mitigation costs.

Maintenance Dredging Permitting for Multiple Terminals-Water-Environment-Consultants
Savanah, GA

Maintenance Dredging Permitting for Multiple Terminals

• WEC provided permitting support for a number of Savannah Harbor commercial terminal owners (including Georgia Ports Authority, ConocoPhillips, Georgia-Pacific Gypsum, NuStar Energy, and others) to conduct maintenance dredging in the Savanah Harbor.

• The project, which included 20 terminals in total, required careful consideration of environmental effects, water quality standards, and fishery resources. WEC conducted Tier I Sediment Quality Evaluations, an Essential Fish Habitat Assessment and Biological Assessment, and evaluated water quality effects in support of the permit applications.
