Idaho Power began field surveys in 2010 and continues fieldwork in 2013 to support the NEPA and EFSC processes. Crews work in small teams and surveys should not result in any ground disturbance. Fieldwork throughout the project corridor may include one or more of the following:
- Land surveys
- Terrain and access road surveys
- Biological resources studies
- Cultural resources studies
- Sound monitoring
Engineers and surveyors are conducting reviews of the topography and land features, as well as evaluating corridor accessibility from public rights of way, to identify where access roads and landowner permission may be needed. This work should not result in any ground disturbance.
To help with the terrain surveys, land surveyors are setting control monuments along the proposed project corridor; however, no monuments are planned on private land at this time. A GPS base unit takes a reading over each monument to establish precise positions and coordinates to allow for accurate and repeatable control positioning for Idaho Power as long as the transmission line is in use.
Archeologists are looking for cultural resources (archaeological or historic sites). If cultural resource sites are discovered, archeologists will work with the State Historic Preservation Officers in Idaho or Oregon, and other interested parties, to determine which sites meet the criteria for listing on the National Register of Historic Places. Crews work in small teams on foot, and this work should not result in any ground disturbance.
Biologists are conducting surveys to classify the types of vegetation and wildlife habitats present along the proposed route and surrounding areas. Biologists also survey for threatened, endangered, and other sensitive species according to protocols established by BLM, USFS, U.S. Fish and Wildlife Service, and either Oregon Department of Fish and Wildlife or Idaho Department of Fish and Game. These include surveys to determine the presence of specific species or their habitats, for example sage-grouse leks, raptor nests and Washington ground squirrel colonies. Because different species require specific survey protocols, work could occur throughout the day and night and require ground or aerial access. Biological resource reports are being reviewed by appropriate federal and state agencies. Crews work in small teams, and surveys should not result in any ground disturbance.
