Environmental Studies

Pursuant to NEPA and CEQA regulations, projects are closely evaluated for impacts on the community, the natural environment and the population’s heath and welfare. The environmental document incorporates multiple study results, community input and ideas, and documents the reasons for which decisions are made. The environmental process for the Centennial Corridor project will evaluate a range of alternatives that meet the project’s purpose and need, including various “build” and one “no-build” alternatives. Following the completion of numerous studies, a draft environmental document will be presented to the public for comment.

Environmental Effects

Probable effects of the project include impacts to farmland, residences, businesses and industrial uses; visual resources; cultural resources; water quality; air quality; noise standards; and biological resources. The following technical studies will be prepared as part of the EIR/EIS:

  • Community Impact Assessment
  • Relocation Impact Studies
  • Natural Environment Study
  • Visual Impact Assessment
  • Air Quality Study
  • Noise Report and Noise Abatement Decision Report
  • Historic Property Survey Report (historical architecture, historic resources, and archaeological resources)
  • Initial Site Assessment (hazardous materials)
  • Floodplain Study
  • Water Quality Report
  • Paleontological Studies
