Environmental + NEPA

Our highly collaborative and interdisciplinary approach allows us to effectively manage environmental concerns, regulatory requirements, funding strategies, public and agency coordination, and technology solutions with the needs of transportation infrastructure projects.

We develop methods and strategies that are attentive to regulatory bodies, socially responsible and scientifically sound, while minimizing timeframe and costs.

HR Green implements the procedural requirements of NEPA in accordance with individual agency policies, procedures and preferences. We prepare NEPA documentation for a variety of federal actions ranging from permitting decisions to major funding allocations. Clients rely on us to identify the resources within the project study area and determine the necessary steps to comply with NEPA and other federal and state laws such as the Clean Water Act, National Historic Preservation Act and Threatened and Endangered Species Act.
