P57. Request Preliminary Environmental Analysis Report (PEAR)

The Preliminary Environmental Analysis Report (PEAR) provides the initial environmental evaluation of a project and all feasible alternatives before it is programmed in the State Transportation Improvement Program (STIP) or State Highway Operation and Protection Program (SHOPP). The PEAR also evaluates the impacts on the scope, schedule, and costs associated with completing environmental compliance. Because the environmental process can have a substantial impact on the project alternatives, design, costs, schedule, and delivery, the PEAR must clearly present and discuss the results of preliminary environmental studies in order to identify potential environmental constraints and risk that may affect design and delivery. The information contained in the PEAR serves as the foundation for the environmental team to begin studies in the Project Report phase, facilitating early consultation with Federal and State resource agencies and thereby identifying timeframes for environmental processes.

The PEAR identifies the specialists and studies in District Environmental Planning that would be needed in the next project delivery phase:

  • Cultural Resources
  • Biology
  • Socioeconomic/Community Impacts
  • Noise
  • Air Quality
  • Palenotological Resources
  • Water Quality
  • Floodplain
  • Hazardous Waste
  • Scenic Resource Evaluation
  • Visual Impact Analysis
  • Storm Water Quality Assesment

Preliminary alternatives must be identified prior to submitting a PEAR request.

Coordination between the Environmental PDT representative and the project manager will be needed for seasonal studies that will dictate the schedule for environmental document completion.

This task is not required when the District Environmental Manager in conjunction with the FHWA determines and certifies that the project is Categorical Exempt/Excluded from the requirements of CEQA and NEPA.
