Our Coastal Resilient Infrastructure Work
Tetra Tech completed the conceptual design, alternatives analysis, and 35 percent level design for the seawall replacement to support alternative visions and opportunities for redeveloping the central waterfront area.
Our team designed and provided construction management for a 15-acre island breakwater system to provide wave and current protection for the hurricane impacted marina. ASCE’s Coasts, Oceans, Ports, and Rivers Institute (COPRI) recognized Tetra Tech’s work on the Florida’s Fort Pierce City Marina as the 2016 Top Large Project of the Year. The National Association of Environment Professionals recognized the project with a 2017 National Environmental Excellence Award.
Tetra Tech designed 21 miles of shoreline protection using living shoreline products to attenuate wave energy, serving as a first line of defense for coastal marshes in the project area.
