NEPA & State Equivalent Processes

At Ardurra, we help clients and communities navigate complex environmental requirements with confidence and clarity. Our specialists turn regulatory challenges into streamlined pathways that protect natural resources while advancing essential infrastructure projects. With comprehensive expertise in the National Environmental Policy Act (NEPA) and state equivalent processes, such as the California Environmental Quality Act, we provide seamless support that keeps your projects moving forward responsibly, from initial planning through final approvals.

We partner with key federal and state agencies to develop strategies that meet rigorous compliance standards while keeping projects on schedule. Our agency relationships span the U.S. Department of Transportation (including the Federal Highway Administration, Federal Aviation Administration, Federal Transit Administration, and Federal Railroad Administration), plus the U.S. Coast Guard, U.S. Army Corps of Engineers, Space Force, Federal Emergency Management Agency, Department of Housing and Urban Development, and U.S. Fish and Wildlife Service.

Our federal and state program support includes manual development, quality control procedures, document review and oversight, regulation analysis, and process compliance guidance. We also assist states pursuing NEPA assignments through development, implementation, and comprehensive training.

For Impact Assessment services, we prepare NEPA documentation across all action classes: Categorical Exclusions, Environmental Assessments, and Environmental Impact Statements. Additional services include FAA Environmental Due Diligence Audits (Phase I & II), Habitat Conservation Plans, wetlands assessment, Incidental Take Permits, and mitigation planning.

We deliver solutions that protect environmental resources, address stakeholder concerns, and advance projects efficiently, responsibly, and with precision.
