National Environmental Policy Act (NEPA) Studies
A detailed environmental review of the preferred solution, supported by public involvement and coordination with review agencies.
NEPA Documentation
Engaging the public and adopting an interdisciplinary methodology are integral components of the NEPA decision-making process. Our team possesses extensive familiarity with NEPA regulations and is highly proficient in producing a variety of NEPA documents including Categorical Exclusions, Environmental Assessments, and Environmental Impact Statements.
When seeking federal funding, a thorough assessment of environmental, social, and economic consequences is frequently necessary before any improvements can proceed. To streamline the NEPA process, we create well-considered project purpose and need statements. These statements serve as guiding principles as we craft appropriately scaled solutions that prioritize avoiding or minimizing negative effects on environmentally sensitive areas.
Planning & Environmental Linkages
When designing location plans for new or upgraded transportation corridors, we adhere to the Planning and Environmental Linkages (PEL) approach. This method involves integrating environmental and community considerations from the outset. By doing so, we establish strong connections, simplify project implementation, and ultimately create transportation initiatives that align more effectively with the community’s requirements.
