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 41^st Avenue and Soquel Drive and a pedestrian/bicycle overcrossing of Highway 1 at Chanticleer Avenue.

The full environmental document is provided below.
