The U.S. Environmental Protection Agency’s (EPA) Office of Wastewater Management selected Tetra Tech to serve as the lead contractor on its Green Infrastructure Technical Assistance program for cities and nonprofit groups that want to implement green infrastructure projects. This infrastructure practice uses plants, soils, and nature to manage stormwater and create healthier urban environments. Tetra Tech worked with EPA to prepare nearly 50 policy, modeling, and conceptual design projects that address specific green infrastructure barriers. These projects served as case studies in the recently released report titled Tools, Strategies and Lessons Learned from EPA Green Infrastructure Technical Assistance Projects.

This report offers guidance and inspiration to communities to look into green infrastructure to improve community space and ultimately quality of life. The report defines green infrastructure and discusses benefits for the community such as water quality improvements and water conservation, local economy strengthening, and community and infrastructure resilience enhancement. The report helps match potential problems with tested solutions and offers resources for readers to gain further knowledge about these infrastructure practices. Tetra Tech’s team also worked with EPA to create a technology guide and a benefits table that users can share with potential stakeholders for future projects.

The case studies included in the report illustrate real-world solutions and how these practices can be applied in local communities. For example, the report discussed a project in Santa Monica, California, where Tetra Tech and EPA developed plans to create a green infrastructure water harvesting system for a local park. The designs included a cistern and a half-acre-foot underground infiltration gallery that could supply up to 100 percent of the park’s approximately 450,000–gallon-annual irrigation demand.

Tetra Tech is excited to have worked on such a cutting-edge project and report to help communities manage their water resources and increase community resilience.
