The I-15 Improvement Project proposes several potential environmental impacts and risks at the project study boundary. The need for an environmental assessment resulted in the production of the Preliminary Environmental Analysis Report (PEAR), a Caltrans directive that documents issues and assumptions to be addressed by the National Environmental Protection Agency (NEPA) and California Environmental Quality Act (CEQA). The PEAR will determine the anticipated environmental approval for the project at the I-15 and Franklin Street Interchange.
Preliminary Environmental Analysis Report (PEAR)
The PEAR briefly introduces the I-15 Improvement Project and restates the purpose and needs. It explains each proposed alternative and assesses any initial environmental doubt. Special environmental constraints that may require future environmental processes are explained in the PEAR. Anticipated environmental commitments by impacted resources are summarized briefly. The permits and approvals necessary for the project are listed. The timeline to acquire them are shown. Any important consideration that might affect the level of effort and resources are assumed. The PEAR continues with a summarized study of common environmental issues. These issues are environmental risks that usually affect a project's delivery. An anticipated environmental approval is determined at the conclusion of the report to explain what documentation will be required in the next phase of the environmental analysis.
Pear Key Statements:
- 8.7 Hydrology and Floodplain: The project study boundary lies on a 100 year floodplain. Alternatives will be altered to mitigate this issue.
- 8.10 Paleontology: The project study boundary includes areas with high and low risks of exposure to paleontological sensitivity.
- 8.12 Air Quality: There will be reduced traffic emissions within the city with the implementation of the new alternative.
- 8.13 Noise and Vibration: If the noise activity of vehicles driving on the new interchange is measured at 80 decibels or above, a sound wall will be constructed
- 8.15 Biological Environment: Endangered species within the project study boundary will require site surveys to be performed for activity and location checks.
