The proposition would amend the state’s landmark environmental review law, the California Environmental Quality Act (CEQA), to expedite specific “essential” projects, including housing, transportation, water, health, wildfire mitigation, educational buildings, internet access and clean energy projects. It would set a 365-day time limit on these environmental reviews and require courts to rule on CEQA-related lawsuits within 270 days. There is debate as to whether its language could be construed to include data centers.
Yes Argument
California’s system for approving housing, water, clean energy, roads, schools, hospitals and wildfire prevention is too slow, bureaucratic and costly. Proposition 45 would set enforceable timelines for project approvals, streamline legal challenges and reduce frivolous lawsuits. Projects would still undergo environmental review and cities and counties could still approve or deny them. The proposition excludes Delta conveyance, nuclear power and high-speed rail projects.
No Argument
Proposition 45 limits the environmental review of major development projects and the public’s right to be heard. It reduces public agency requirements to consider public comments on proposed projects — comments that often expose potential contamination of air and water or damage to our coast, rivers and wildlife. It was written by a business group and financed by gas and electric utilities and corporate PACs.
