Environmental Planning and Impact Assessment

ERG provides a broad spectrum of National Environmental Policy Act and related environmental planning and impact assessment services to federal agencies and in support of federally funded programs and projects. Our team of planners, scientists, engineers, compliance experts, and public engagement specialists supports all aspects of the NEPA process, including pre-scoping and initial planning, public scoping, field surveys, impact analysis, inter- and intra-agency coordination, public comment management, assessment of regulatory requirements (e.g., federal cross-cutters), and federal decision-making. We tailor our analyses to the project, developing concise and efficient environmental assessments for simpler, fast-tracked projects and robust, detailed environmental impact statements for more complex projects with significant impacts. In parallel, we lead or manage the environmental consultation processes throughout the environmental review. As applicable to the review, ERG also collects data and conducts field investigations, including wetland delineations and ecological surveys, and works with trusted subcontractors to provide additional services, including archeological and historic architectural investigations. Our NEPA team stays abreast of the frequent changes in the policy and regulatory landscape so we can help clients adapt and modify their NEPA programs to ensure they are meeting current requirements.

My lived experience growing up in a rural community showed me the importance of engaging disparate voices in developing sustainable solutions to address our most pressing environmental challenges. Now, as an environmental engineer and policy analyst, I am grateful that I can apply my experience to support a broad range of meaningful work, including advancing a circular economy, supporting clean energy solutions, and community engagement.

Federal agencies must consider and mitigate the effects of their actions on the natural and human environment. With evolving mission and regulatory requirements, community interest, and expanding inventories of natural and historic resources, fulfilling this responsibility can be challenging! I am proud to help my clients meet critical mission requirements while serving as stewards of our environment.

Kort Kirkeby

Much of my childhood was spent outdoors observing, collecting, and understanding the natural world. This early passion led me to study biology, communications, and environmental engineering, and ultimately to integrate them into my career in aquatic ecosystems. I have had great opportunities to work with outstanding people and manage large-scale projects across the U.S.  I am passionate about delivering high-quality work products that meet and exceed expectations.
