Highway 1 Corridor Investment Program Environmental Documents


The Santa Cruz County Regional Transportation Commission (RTC), in cooperation with the California Department of Transportation (Caltrans) and the Federal Highway Administration (FHWA), has prepared the Highway 1 Tier I/Tier II Environmental Impact Report/Environmental Assessment. For purposes of environmental analysis, the project is divided into two components:

  • Tier I – A long term, program level analysis for the future of the Highway 1 corridor between Santa Cruz and Aptos. The Tier I concept for the corridor would be built over time through a series of smaller incremental projects (referred to as Tier II projects).
  • Tier II – Project level analysis for auxiliary lanes between 41st Avenue and Soquel Drive and a pedestrian/bicycle overcrossing of Highway 1 at Chanticleer Avenue.

The full environmental document is provided below.
