Environmental, Regulatory, & Public Outreach Services

At Gannett Fleming, we leverage science, technology, and ingenuity to create resilient and sustainable solutions for a better planet.

From protecting and preserving natural ecosystems, solving challenges in the natural and built environments, or assisting clients with compliance, investigation, and remediation related to human environmental health and safety, we help clients successfully achieve project goals and maintain business operations.

Environmental Impact Assessment Services

Our interdisciplinary team has a long and rich history of helping clients advance their projects following the National Environmental Policy Act (NEPA), the Canadian Impact Assessment Act, and their state and provincial equivalents. We are armed with:

  • A comprehensive understanding of the regulatory framework governing project development.
  • A solid understanding of agency requirements and processes.
  • Creativity.
  • Exceptional communication skills.

Experienced in providing Environmental Impact Assessment (EIA) services to federal, state, and provincial agencies across North America, we understand that an EIA is a fundamental planning and decision-making process and tool. Public outreach and engagement are done with purpose and skill—streamlining the relevant issues to be analyzed—leading to timely approvals. Our documentation, the most lasting and visible evidence of our work, is clear, concise, and “tells the story” to help inform stakeholders.

Public Outreach and Engagement

Making connections with the people, communities, and other stakeholders impacted by projects starts with the understanding that all perspectives are vital to a project’s success. We leverage constructive engagement techniques to help groups and individuals understand each other’s viewpoints. Using decision-support tools, we bring structure to the analysis required when considering the impacts—both positive and negative—of public decisions.

Our outreach and engagement services adhere to essential consultation principles, including:

  • Openness and inclusivity.
  • Accountability.
  • Flexibility.
  • Clarity.
  • Coordination.
  • Timelines.
  • Public accessibility.
  • Digital tools, including social media and virtual meeting platforms, serve as an effective means to engage with valued stakeholders. Our virtual public outreach platform provides a cost-effective way to reach many people that may not otherwise have their voices heard.

Compliance & Documentation Services Include:

  • Planning & overall process management.
  • Workshops to develop needs & alternatives.
  • Environmental impact statements.
  • Administrative records.

Ecosystem Restoration

Ecosystem restoration is much more than simply restoring the land and water on which animals and plants depend. Done well, it aids habitats and species by restoring lost natural functions and productivity and adding biodiversity and value to humankind.

Our diverse teams focus on repairing the damage to natural ecosystems and seek to return them to an earlier state or to one that closely resembles an unaltered condition. Experienced in many forms of ecosystem restoration, including streams, our core offerings include:

  • Ecological surveys, inventories, and assessments.
  • Stormwater pond retrofits and facilities.
  • Wetlands enhancement and creation.
  • Coastal engineering and “living” shoreline protection.
  • Habitat enhancement and creation.
  • Invasive species control.

Natural Resources & Permitting

Public and private sector clients across the country rely on Gannett Fleming to provide comprehensive natural resources investigation, analysis, and permitting assistance. Our biologists and ecologists have extensive experience conducting a variety of species surveys, delineations of the Waters of the U.S. rule, habitat assessments, and biological assessments according to Section 7 of the Endangered Species Act. We routinely develop and assist with constructing mitigation measures and projects to offset unavoidable impacts on natural resources.

We partner closely with our clients, regulators, and resource agencies to develop permit conditions to benefit all parties and the environment. As a result, we maintain an extensive library of construction details, specifications, and best management practices to fit each unique scenario.

Our thorough knowledge of federal and state regulations governing environmental protection facilitates the efficient preparation of regulatory permit applications. This helps clients avoid delays and impacts to schedule. Our comprehensive solutions include:

  • Ecological surveys, inventories, and assessments.
  • Stormwater pond retrofits and facilities.
  • Wetlands enhancement and creation.
  • Coastal engineering and “living” shoreline protection.
  • Land use permitting requirements.
  • Habitat enhancement and creation.
  • Invasive species control.

Socioeconomic Planning, Analysis, and Stakeholder Engagement

Environmental justice, equity, and social and health impact assessments and the role each plays in project development are critically important. Likewise, stakeholder engagement is integral to all environmental impact assessments — particularly when identifying issues and concerns related to the social environment and responsible land use.

Gannett Fleming has the in-house expertise to design, analyze, and implement a variety of socioeconomic impact assessment studies. Our land use planners, population and other demographic specialists, and economists are skilled in inventorying complex conditions and preparing rigorous assessments of a project’s economic and social impacts and benefits.

Our comprehensive and practical experience with a wide range of actions and conditions assures the early identification and recognition of social issues critical to success. We are adept at developing community and stakeholder engagement plans and programs to solicit input that leads to more informed decision making.

Acoustics, Noise, and Vibration

The effects of noise pollution can be significant. Concerns about disturbances from noise pollution can create delays for your project. Working with top-quality noise and vibration analysis can help address and manage noise sources and issues during a project’s design and construction phases. Our professionals solve noise and vibration problems for all types of projects, including:

By measuring and analyzing acoustical or vibration characteristics using sophisticated instrumentation, our team can meticulously determine noise and vibration impacts by comparing existing levels and predicting future levels with established criteria. Gannett Fleming provides full-service acoustical engineering and design services, including detailed noise abatement design.

Unique to Gannett Fleming, our Sounds of Transit and Sounds of Highway tools provide the public with simulations of the sound levels of a proposed project. This lets them hear what they can expect from the project after construction, vastly improving stakeholder education and engagement.

Environmental Safety & Health

Complex rules and regulations exist to protect human health and safety as well as that of the environment. At Gannett Fleming, our environmental engineers, scientists, and planners help you achieve environmental compliance while avoiding adverse impacts and carrying out business objectives. By keeping pace with evolving environmental regulations and practices, we help both public- and private-sector clients:

  • Assess and manage risk.
  • Identify and investigate impacted areas.
  • Develop management strategies to protect resources.
  • Establish restoration goals.
  • Discover opportunities for improvement.

Our expertise with federal, state, and provincial jurisdictions’ regulatory compliance requirements and permitting includes:
