Roth Ecological Design International (REDI) is a global leader in strategic water planning and green infrastructure design. We create innovative, integrated solutions to meet the 21st-century challenges of water quality, quantity, and climate resilience. Our mission is to reconnect communities and developments with sustainable water management practices that mimic natural hydrology, regenerate ecosystems, and enhance long-term resilience.

 

By studying the hydrological, ecological, and cultural history of each project site—alongside projected climate impacts—we develop solutions that strengthen water security, diversify supply, prevent pollution, and support climate adaptation. On site-specific projects, REDI often serves as the critical link between civil engineers and landscape architects, ensuring that sustainable water systems and green infrastructure are seamlessly embedded into design.

 

Ultimately, our goal is to provide regenerative strategies that don’t just reduce impact, but actively produce water resources—restoring water quality, supporting biodiversity, and building climate-resilient communities
