Our interdisciplinary team helps clients advance their transportation, energy infrastructure, watershed, land use, and site planning projects in compliance with federal, state, and provincial laws and regulations.

With a deep understanding of regulatory frameworks and a consensus-building approach, we anticipate and resolve potential issues effectively. Our National Environmental Policy Act (NEPA), Canadian and Ontario Environmental Assessment Acts, and related analyses are fundamental planning and decision-making tools. We conduct purposeful public and agency engagement to streamline issues and achieve timely approvals. Our precise, concise documentation effectively communicates with stakeholders and regulators.

We enhance habitat and species diversity by restoring natural functions and productivity to watercourses and landscapes. Our award-winning stream restoration practice employs natural stream channel design, floodplain reconnection, armoring, grade control structures, and adaptive management to restore hydrologic functions in wetlands, streams, floodplains, forests, and disturbed areas. We evaluate baseline conditions, assess impacts, and provide detailed design plans, permit documents, and construction oversight.

Our projects improve nutrient and sediment retention, stormwater filtration, impervious surface runoff management, and vegetation stabilization. Our comprehensive solutions include reforestation services, invasive species control, fish passageway design, wetland enhancement, dam breach design, wildlife habitat improvement, and contamination cleanup.

Public and private sector clients throughout North America rely on Gannett Fleming for comprehensive natural resources investigation, analysis, and permitting assistance. Our natural resources teams work with our engineers to identify impact avoidance opportunities and secure project permits.

Our wetland scientists, biologists, and ecologists are industry experts with extensive experience in baseline inventory work, species surveys, wetland and waterway delineations, habitat and water quality assessments, macroinvertebrate assessments, and dredging and contamination assessments.

We support public utilities, infrastructure, residential developments, transportation, and power projects, coordinating with federal, state, local, and provincial agencies to achieve compliance and award-winning success.

Our economists conduct benefit-cost analyses for water resources, transportation, and land use projects, aiding decision-makers in weighing the benefits of an action against the investment required. These analyses consider quantitative and qualitative benefits, including tradeoffs between ecosystem services. Our expertise includes consequence analysis modeling for hazard events and risk consideration in selecting a path forward.

With long-standing experience in economic impact analysis, we assess how projects may affect employment, income, tax revenue, and regional business communities. Using input-output modeling and other quantitative methodologies, we measure and communicate economic changes.
