Parsons Transportation Group
Hart Crowser is the Habitat Lead on the multidisciplinary engineering team to replace the 7,000-foot aging Elliott Bay seawall along the Seattle waterfront. We are responsible for managing the design of several habitat features associated with the project. Our work involves:
- Designing marine aquatic habitat features.
- Designing a 7,000-foot nearshore juvenile salmon habitat corridor that includes light penetrating surfaces.
- Designing a pocket beach with indigenous riparian zone, saltmarsh eco-bench, and an offshore large rock kelp reef system.
- Preparing the Basis of Design document and all design specifications for habitat features.
- Providing scientific and habitat input to a large multi-disciplinary team of design, structural, traffic, storm water, geotechnical and coastal engineers to maximize beneficial ecological functions within the total design.
- Interacting with the City of Seattle, stakeholder groups, and urban design specialists to provide habitat benefits that allow for a structurally safe new seawall and the significant amenities and aesthetics of a modern urban waterfront.
