Cultural and Natural Resources

The National Historic Preservation Act of 1966 (NHPA) was enacted more than 50 years ago. In addition to establishing the National Register of Historic Places, Section 106 of the NHPA requires Federal agencies to consider the effects of their actions on historic districts, buildings, and sites. States and municipal governments followed with their own historic preservation laws that applied to state lands and, in some cases, to privately held lands. This gave rise to what is commonly referred to as cultural resources management—a field that is broad in nature and includes survey work and agency-based consultation with state and local governments, tribal councils, and interested members of the public.

Our professionals are environmental scientists, archaeologists, former SHPO staff members, and experienced program managers. This first-hand knowledge helps us advise our clients how to negotiate the regulatory scene in compliance with NHPA, NEPA, and other laws, executive orders, instructions, and policies.
