Coastal Resilience
Tetra Tech delivers innovative, nature-based solutions and structural design for coastal communities seeking climate-resilient flood risk reduction and marine habitat restoration.
Our interdisciplinary team is Leading with Science® to create industry-leading design solutions for some of the most complex issues facing coastal communities and ecosystems around the world. With climate change driving sea level rise, stressing marine life, and creating more frequent and intense weather events, we support our clients with sustainable and scalable solutions to protect and restore coastal environments.
Since our founding in 1966, we have employed high-end technologies and approaches to condition and risk assessments, project feasibility studies, and data-driven decision tools that capture all social and environmental benefits generated by an array of possible solutions. Our teams deliver sustainable, nature-based, and structurally sound solutions that are resilient and exceed client expectations—from designing a living shoreline or surge barrier protection system to assisting local communities with planning for a sustainable, blue economy.
Numerical Modeling and Predictive Analytics
We simulate the impact of the changing climate on our environment and use our suite of Tetra Tech Delta technologies to design optimal, nature-based solutions and manmade adaptations.
- Coastal and stormwater modeling
- Computational fluid dynamics
- Climate change and sea level rise modeling
- Remote sensing, geographic information systems (GIS), and artificial intelligence (AI)
Living Shorelines
Tetra Tech designs living shorelines to reduce erosion, restore and sustain natural habitats, and increase coastal resiliency. We provide our clients with the social, economic, and environmental data they need to make informed decisions regarding shoreline protection.
- Natural and biological resources impact assessments and mitigation plans
- Coral reef, oyster bed, and sea grass restoration
- Dune and estuary restoration
- Socioeconomic and environmental benefit decision tools
Coastal Flood Risk Reduction
Our hazard mitigation and resilience planners, engineers, and asset management specialists help coastal communities and infrastructure owners reduce flood risk across the full asset cycle. We incorporate the effects of climate change, sea level rise, storm surge, and extreme weather into strategies that improve community flood protection and the long-term resilience of critical coastal infrastructure. Our multidisciplinary teams plan, design, assess, and support the management of structural and nature-based flood risk reduction systems, including levees, storm surge barriers, navigation and floodgates, seawalls, bulkheads, canals, diversions, and pumping systems. We also help owners understand the condition, performance, reliability, and remaining service life of these assets so they can prioritize maintenance, rehabilitation, and capital investment.
- Climate change, storm surge, and sea level rise planning
- Coastal flood risk and vulnerability assessments
- Levees, surge barriers, gates, seawalls, and pumping systems planning and final design
- Flood risk reduction planning, life cycle cost estimating, and socioeconomic benefit assessment
- Stakeholder engagement, legislative review, and funding management
