This practice provides a broad range of engineering services to support design work in the coastal zone, working with natural oceanographic and geologic processes to design sustainable and resilient coastal projects.
Feasibility studies and design strategies for erosion mitigation, specializing in both traditional structures and green or nature-based approaches.
Hydro-morphological optimization and design of channel openings, roadway bridges, and tidal wetland restoration to restore degraded coastal ecosystems.
Comprehensive design of beach nourishment projects, including coarse or mixed-sediment sorting analyses, offshore borrow site evaluations, and post-construction monitoring.
Utilizing advanced state-of-the-science analysis techniques, this team simulates estuarine hydrodynamics and coastal processes to support management and restoration strategies.
Numerical modeling of waves, currents, and sediment transport to identify sources, sinks, and pathways within complex estuarine systems.
Water quality and watershed-embayment nitrogen management modeling to determine assimilative capacity and establish TMDLs.
Oceanographic measurement and monitoring campaigns using tide gauges, current meters, CTDs, and bathymetric survey equipment to validate models.
This practice offers specialized environmental consulting to assess potential project impacts and navigate complex environmental regulatory frameworks at local, state, and federal levels.
Detailed assessments of existing conditions and evaluations of potential impacts caused by engineering activities on coastal processes.
Formulation and implementation of permitting strategies for complex coastal engineering projects, ensuring compliance with local, state, and federal regulations.
Preparation of National Environmental Policy Act documentation and other environmental regulatory papers required for coastal zone activities.
