01
Core Decision and Immediate Impact
The San Diego City Council voted unanimously on Tuesday to place a 45-day moratorium on permitting, approval and construction of new data centers within city limits, except for projects essential to public safety. City staff have 180 days to deliver preliminary recommendations on how data centers might affect electricity demand, water supplies, housing availability, land use and neighborhood quality. The ordinance allows an extension of up to ten months and fifteen days, with any further extensions requiring a four-fifths vote.
02
Background and Context
Rapid growth in artificial-intelligence computing has spurred interest in large-scale data facilities that consume vast amounts of power and water. San Diego already faces high residential electricity rates and a severe housing shortage, prompting officials to examine whether new data centers could exacerbate utility costs and limit land for affordable homes. The proposed site for the largest contemplated facility is the 70-acre Naval Information Warfare Systems Command (NAVWAR) property near Old Town, a federal parcel long discussed for redevelopment.

Timeline
- October 22 – Mayor Todd Gloria signed an executive order directing the planning department to draft a temporary moratorium.
- Following week – The council voted unanimously to adopt the 45-day moratorium and establish a Data Center Stakeholder Working Group.
- 180 days after the vote – City staff must present preliminary regulatory recommendations.
04
Data & Statistics
- Manchester Financial Group has floated a 400-megawatt data center for the NAVWAR site, a capacity that would power roughly 300,000 homes and could consume electricity comparable to more than 320,000 homes.
- At 400 MW, the facility would be the largest data center in California.
- The NAVWAR parcel spans 70 acres; the broader redevelopment plan envisions 8,900 residential units and two hotels with 480 rooms.
- The moratorium’s initial 45-day period can be extended twice, potentially reaching nearly two years of pause time.

Official Statements & Responses
Council President Joe LaCava called the public’s reaction “clear, unambiguous and passionate” against data centers. Councilmember Marni von Wilpert stressed that any future AI data center must cover its own utility costs without burdening ratepayers. The mayor’s office announced a stakeholder working group comprising technology experts, utility professionals, housing advocates and community representatives.
06
On-the-Ground Reports
The council hearing attracted roughly 70 speakers, many voicing opposition, including participants dressed as Elmo and Lord Farquaad. A handful of voices, like Francisco Martinez, expressed openness to data-center development if land were unused, emphasizing a need to balance technological progress with neighborhood preferences.
07
Conflicting Reports & Gaps
Because NAVWAR is federally owned, the city’s moratorium cannot directly block a data center on that parcel, rendering the measure largely symbolic for the specific site. Developers have not finalized any design, and Ted Eldredge, president and CEO of Manchester Financial Group, indicated that the 400-megawatt proposal is “not married to that megawattage” and depends on market conditions. No negotiations with energy providers have been confirmed, leaving the actual utility impact uncertain.
08
What’s Next
The Data Center Stakeholder Working Group will submit its recommendations within the 180-day window. The council may vote to extend the moratorium for up to ten months and fifteen days, after which any permanent regulations would need council approval. State and federal legislators are also considering broader data-center legislation, such as the Bipartisan American Affordability and Jobs Act of 2026, which could influence how facilities on federal land are regulated.
