SCAG's PEIR is an environmental report that will analyze and disclose potential impacts of the Connect SoCal plan on the environment. The report is required under law by the California Environmental Quality Act (CEQA). SCAG’s PEIR will provide a region-wide assessment of potential significant environmental effects of Connect SoCal as well as consider broad policy alternatives and program-wide mitigation measures. More importantly, the PEIR provides a foundation for subsequent, project-specific environmental reviews that will be conducted by local implementation agencies.
What will the PEIR Analyze?
The PEIR is a programmatic document that will analyze potential effects of Connect SoCal on the environment. Although the Connect SoCal plan includes many transportation projects, the PEIR does not specifically analyze environmental effects of any individual transportation or development project. Project-level environmental analyses will be prepared by implementing agencies on a project-by-project basis as projects proceed through the design and decision-making process. SCAG's PEIR will analyze:
- Aesthetics and Views
- Agricultural and Forestry Resources
- Air Quality
- Biological Resources and Open Space
- Cultural Resources
- Geology, Soils and Mineral Resources
- Greenhouse Gas Emissions and Climate Change
- Tribal Cultural Resources
- Hazards and Hazardous Materials
- Hydrology and Water Quality
- Land Use and Planning
- Population and Housing
- Transportation, Traffic and Safety
- Public Services and Utilities
