In partnership with our clients, Tetra Tech develops cost-effective restoration and nature-based solutions, addressing risks and impacts from climate change and biodiversity loss, no matter how complex.

Our interdisciplinary teams of scientists and engineers conduct assessments and surveys to characterize historic and current terrestrial and aquatic conditions, develop approaches to restore degraded conditions, mitigate against future losses, preserve intact ecosystem functions, and provide real-time data management and expertise at all points of implementing restoration and nature-based solutions.

Our teams work across the globe to create customized, sustainable, and scalable solutions to restore degraded conditions through nature-based approaches. We focus on delivering solutions that address the biggest resource needs and risks, provide other ecosystem benefits, and are economically feasible. We work across all habitat types from montane, riverine, and grasslands to urban, coastal, and offshore environments. We bring the right solutions to the challenge at hand—whether designing restoration plans for local communities or developing comprehensive watershed action plans for national governments.

Coastal Resilience

As communities adapt and respond to more frequent and extreme flooding and sea level rise, there is an increased need for nature-based solutions to increase green space, protect infrastructure, and provide ecosystem enhancements. Our teams weave natural features and processes in an engineered capacity to create customized and sustainable solutions for coastal resilience.

  • Living breakwaters
  • Resilient waterfront parks
  • Living shorelines
  • Storm surge barriers
  • Shoreline stabilization
  • Coastal and marine habitat restoration for flood risk reduction
  • Adaptation planning and design
  • Coastal resilient infrastructure design

Watershed Restoration

At Tetra Tech, we’re all about collaboration and teamwork. We work with our clients to conduct watershed and stream assessments that dive deep into understanding the unique conditions of each environment.

Armed with scientific and engineering expertise, we develop tailored solutions to restore degraded areas and bring back natural beauty. Our approach is to harness the power of ecologic, hydrologic, and geomorphic processes to create sustainable and long-lasting transformations. Together with our clients, we embark on a journey to revitalize ecosystems, making the world a greener and healthier place for generations to come.

  • Water resources management
  • Hydrologic, hydraulic, and geomorphic modeling
  • Climate change evaluations
  • Watershed assessments
  • Desired conditions identification
  • Prioritization and action plans
