California Proposition 45 Debated Over Data Center Development Oversight

News ClipSan Diego Union-Tribune·San Diego, San Diego County, CA·9/30/2026

An opinion piece from a San Diego City Council member urges voters to reject California's Proposition 45, a statewide ballot measure. The proposition is criticized for potentially fast-tracking data center development and other projects by reducing public oversight and weakening environmental safeguards related to water, energy, and noise. Opponents argue it could lead to increased taxpayer costs and environmental harm, appealing to voters to reject it.

This opinion piece by San Diego City Council member Elo-Rivera urges California voters to reject Proposition 45, a ballot measure that critics argue would weaken environmental safeguards and public oversight for a wide range of development projects, including data centers. The author highlights findings from the Public Policy Institute of California indicating strong public opposition to data center construction, suggesting Proposition 45 is a loophole sought by "powerful interests" like data center developers and the oil and gas industry.

Proposition 45 is presented as a measure that would allow projects, potentially including data centers under a broad "broadband" definition, to bypass local review processes. This would result in shorter public comment periods, fewer alternatives considered, and reduced judicial review for concerns like water and energy consumption and noise impacts, particularly in cities like San Diego.

The article asserts that passing Proposition 45 would lead to significant taxpayer costs, with the nonpartisan Legislative Analyst’s Office estimating implementation costs of over $100 million annually, in addition to future cleanup and disaster response expenses from unchecked industrial and sprawl developments. The author contends that the measure would not guarantee reduced household costs but rather increase pollution and environmental risks.

Elo-Rivera emphasizes the broad coalition opposing Proposition 45, including the League of Women Voters, American Lung Association, and California Professional Firefighters, urging voters to join them in rejecting the measure to protect environmental protections and local control.
