Our mitigation experts develop solutions for impacts on aquatic and upland environments including marine areas, estuaries, lakes, rivers, streams, wetlands, and terrestrial wildlife habitats. We focus on working with clients early in the planning and design of the project to avoid and minimize impacts wherever possible. Where impacts are unavoidable, we offer a variety of solutions including preservation, enhancement, restoration, and creation of habitats to offset project impacts. We assist our clients with selecting appropriate mitigation sites on or off the project site.

Our mitigation and restoration experts are biologists, landscape architects, and engineers who collaborate on mitigation design. Typical projects involve installing large woody debris in streams, creating rearing and spawning habitat for fish, excavating soil in support of wetland creation, amending soil, installing snags for bird habitat, and planting native vegetation communities.

Throughout the design of mitigation projects we coordinate closely with regulatory agencies to insure that the project meets their approval. To ensure successful mitigation, we prepare monitoring, maintenance, and contingency plans for mitigation sites.
