Environmental Planning and Impact Assessment

ERG provides a broad spectrum of National Environmental Policy Act and related environmental planning and impact assessment services to clients including federal and state agencies. Our multidisciplinary team of planners, scientists, engineers, cultural and natural resources specialists, compliance experts, and public engagement specialists supports the full life cycle of environmental review and consultation—from early planning and scoping through decision-making and implementation. We tailor our approach to the scale and complexity of each project, developing concise and efficient documentation for routine or fast-tracked actions, and robust, detailed analysis for complex projects with the potential for significant impacts. In parallel, ERG leads and manages required environmental consultations, coordinating closely with federal, state, Tribal, and local partners to support timely, informed decisions. Our team closely tracks changes in environmental policy and regulations, helping clients adapt and modify their programs to evolving 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.
