Survey & Inventory
Surveys may involve the identification of historic homes in a residential area, the recording of commercial buildings in a downtown district, or the gathering of archaeological information in a remote portion of the state. These surveys are often spurred by agencies or municipalities proposing federal, state, or local projects. OAHP staff is available to assist with the planning and documentation of these surveys.
This information has been collected over the last 50 years and represents extensive field, laboratory and archival research by a wide variety of government agencies, local initiatives, educational institutions, preservation organizations and the general public.
Information from these surveys is summarized in a computerized database and the original forms and documents are stored at OAHP. These resources are available to the public for a variety of research and management uses in addition to those individuals interested in Colorado's rich and diverse cultural resources.
