Shore Protection Structures

High wave energy coastal environments, both marine and freshwater, utilize foreshore structures such as seawalls, flood walls and revetments for flood and shoreline protection of private and public infrastructure in developed areas.

GZA provides comprehensive inspection, engineering and design services for the repair and/or new construction of all foreshore structures and associated improvements. Our design process begins with an assessment of the existing conditions of the Project Site to develop a benefit cost analysis for repair, rehabilitation or full reconstruction with improvements. The design process then continues with the characterization of environmental loads, including analysis of water level and wave frequency data, to establish structure performance requirements and select the resilient design criteria based on Coastal risk. GZA’s designers and engineers include civil and structural engineers and landscape architects, providing complete design services, preparation of construction documents and project permitting.
