PWA is a pioneer in the field of river, tidal and wetland restoration. We specialize in developing a rigorous understanding of the underlying hydrologic and geomorphic causes of environmental degradation. By understanding the cause of the problem, rather than merely the symptoms, we can develop practical and self-sustaining solutions. A particular strength is our ability to develop innovative solutions that maximize environmental enhancement within the constraints of a particular project.

Our expertise includes: inland and tidal creek restoration design, biotechnical bank stabilization and grade control, inland and tidal wetland restoration design, creek daylighting, floodplain restoration, coastal lagoon restoration, fisheries habitat enhancement, fish passage enhancement, surveying, engineering design, production of design drawings and construction bid packages, construction support, pre- and post-project monitoring.
