Sagebrush regularly carries out cultural resources inventories, surveys, and test excavations. These projects frequently include recordation and evaluation of prehistoric and historic sites. In addition, Sagebrush conducts research and studies in specific topical areas like architecture, design landscape and history. This research includes historic and cultural overviews for Major Investment Studies (MIS), evaluations of historic properties and landscape, preparation of historic contextual documents, architectural inventories, assessments of Traditional Cultural Properties (TCP), historic and archival research, archival photography and HABS/HAER documentation.
To date, historic studies in conjunction with proposed construction projects include both project area overviews and contextual histories, which provide background for site eligibility determinations. Structural studies include a large number of inventory projects in both rural and urban neighborhoods containing residential and commercial buildings, as well as industrial and agricultural complexes. In addition, Sagebrush has documented various individual engineering structures such as bridges, hydroelectric plants and dams, mining complexes, railroad trestles and lime kilns.
