Project Spotlights:

Drum Island Marsh Restoration-Water-Environment-Consultants
Charleston, SC

Drum Island Marsh Restoration

• WEC provided expert, technical review and hydrodynamic modeling analysis for the design of the SC Ports Authority’s Drum Island saltmarsh restoration site.

• WEC designed an alternate tidal marsh configuration, resulting in substantial construction cost savings, reduced erosion potential, and reduced maintenance requirements. WEC assisted Collins Engineering with the final design and supported the project team through construction.

• The project won an Engineering Excellence Award from the American Council of Engineering Companies of South Carolina.

Folly Beach Fishing Pier-Water-Environment-Consultants
Folly Beach, SC

Folly Beach Fishing Pier

• WEC teamed with Wantman Group to support the design of a new fishing pier for Folly Beach, South Carolina. The design required an analysis of extreme water levels, currents, winds, scour, and wave forces acting on the structure.

• WEC used the 2D SWAN model to evaluate the wave conditions acting along the pier. The wave load calculations supported a safe and cost-efficient structural design of the new pier.

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.
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.

Kings Grant Mitigation Site Design-Water-Environment-Consultants
North Charleston, SC

Kings Grant Mitigation Site Design

• WEC designed a 43-acre tidal wetland restoration site for Palmetto Railways to meet the needs of the Permittee Responsible Mitigation Plan.

• The project included extensive field data collection and analysis of reference marsh topography, vegetation and hydraulics. WEC used the SRH-2D hydrodynamic model to aid in the design of tidal marsh areas and tidal creeks.

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.
Tronox Mitigation Bank Design-Water-Environment-Consultants
Savannah, GA

Tronox Mitigation Bank Design

• WEC completed a comprehensive, preliminary design of a tidal saltmarsh mitigation bank for Southern States Chemical.

• The design was supported by a 2D application of the HEC-RAS model to simulate tidal inundation through a new box culvert, tidal marsh system, and two railroad crossings. The project required careful consideration of existing site constraints including low-lying roadways, railroads, and offsite flood prevention, while maximizing restored wetland acreage.

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.

Daniel Island Saltwater Mitigation Bank Design-Water-Environment-Consultants
Charleston, SC

Daniel Island Saltwater Mitigation Bank Design

• The South Carolina Ports Authority retained WEC to design the restoration of a former 109-acre dredge spoil area into a saltwater tidal wetland.

• The project required extensive field measurements of tidal water levels, current velocities, and marsh vegetation and 2D numerical modeling to aid the wetland and tidal creek design.

• WEC prepared detailed design drawings and specifications for the wetland site, maximizing restored areas and minimizing construction costs and maintenance requirements.

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.

San Sebastian River Drainage Study-Water-Environment-Consultants
St. Johns County, FL

San Sebastian River Drainage Study

• The County needed to incorporate future risk from sea level rise into stormwater infrastructure improvements for the San Sebastian River drainage basin. To support the County, Applied Technology and Management (ATM) subcontracted WEC to assist them with evaluating combinations of sea level rise and hurricane storm surge in the drainage basin.

• WEC developed a storm surge analysis methodology to include improving the FEMA ADCIRC model for the region. WEC worked with ATM to complete the hurricane modeling analysis.

• The study results provide a more robust assessment of the storm surge and sea level rise scenarios within the upper St. Johns River and tidal tributaries, which the County can incorporate into stormwater infrastructure design.
