Historic Preservation FAQs

Historic preservation identifies, documents, and protects cultural resources—such as historic buildings, landscapes, and artifacts - ensuring compliance with federal, state, and local regulations like the NHPA.

We guide clients through the Section 106 consultation process, including surveys, evaluations, agency and tribal engagement, and the preparation of defensible compliance documentation.

Services include National Register nominations, HABS/HAER/HALS documentation, architectural surveys, archival research, and historic context studies to meet regulatory and preservation standards.

Developers, utilities, government agencies, and other organizations undertaking projects that may impact historic or cultural resources often require preservation services to comply with NHPA and related laws.

By identifying and addressing cultural resource concerns early, historic preservation services help avoid costly delays, reduce regulatory risk, and strengthen stakeholder trust.
