ca-montebello-2026 - Legal basis: Urgency Ordinance No. 2491, "AN URGENCY ORDINANCE OF THE CITY COUNCIL OF THE CITY OF MONTEBELLO, CALIFORNIA, AMENDING TITLE 17 (ZONING) OF THE MONTEBELLO MUNICIPAL CODE TO ESTABLISH INTERIM ZONING CONTROLS FOR ARTIFICIAL INTELLIGENCE (AI) DATA CENTERS," adopted by 5-0 roll call vote, satisfying the four-fifths urgency requirement under Gov. Code 65858. The ordinance's own title does not include the word "Amended"; it was introduced and adopted at the same meeting.
- What prompted it: Regional data center proposals, including Monterey Park's 1977 Saturn Street site about one-half mile away, and concerns over electricity, water, backup generators, noise, infrastructure, land-use compatibility, and environmental impacts
- Affected projects: No Montebello project identified; regional concern tied to nearby Monterey Park proposal
- Detailed status: Expired on schedule around 2026-03-28 (45 days after the corrected February 11, 2026 adoption date). A review of every City Council agenda from 2026-02-25 through 2026-07-27 (the last scheduled meeting before this check) found only the mandatory Gov. Code 65858(d) 10-day report, filed on the 2026-02-25 agenda; no extension, replacement, or further data-center action appears on any later agenda. Montebello separately adopted an unrelated urgency ordinance (No. 2495, adopted 2026-06-24) imposing a moratorium on SB 79 transit-oriented-development applications, which does not affect data centers.
- Outcome: Staff directed to study impacts, coordinate with neighboring jurisdictions, and return with Title 17 zoning standards
Monterey Park
- Type: City
- Status: ⚪ Replaced

- Moratorium ID:
ca-monterey-park-2026 - Legal basis: Ordinance No. 2272; extension Ordinance No. 2274; Gov. Code sections 36937 and 65858
- What prompted it: 1977 Saturn Street data center proposal and broader concern over energy use, noise, air quality, aesthetics, property values, neighborhood quality of life, CEQA review, and whether permanent regulations or a citywide ban are needed
- Affected projects: 1977 Saturn Street proposal by HMC StratCap (SheppardMullin counsel); local CEQA/project records described about 49.9 MW maximum load, 36 MW critical load, 14 backup diesel generators, and roughly 218,400 to 247,480 sq ft in different documents. Per San Gabriel Valley Tribune (2026-04-01), HMC StratCap formally withdrew the Saturn Street application after community pushback; city officials confirmed on 2026-04-20 that HMC StratCap still owns the parcel and has not communicated future plans for the site.

Measure NDC passed at the June 2, 2026 special election (10,388 Yes / 1,372 No, per the LA County Registrar-Recorder's certified canvass); results certified by the City Clerk on June 30, 2026 and declared by City Council Resolution No. 2026-R56 on July 1, 2026 (unanimous, 5-0).

Oakley
- Type: City
- Status: 🟢 Extended
- Date enacted: 2026-04-14
- Normalized date:
2026-04-14(exact) - Duration: 45 days from 2026-04-14, extended 10 months and 15 days by a second urgency ordinance adopted 2026-05-12 (5-0 vote); the combined term runs to the Gov. Code 65858(a) one-year statutory ceiling, approximately 2027-04-13/14.
- Current end date:
— - Sectors: data center
- Moratorium ID:
ca-oakley-2026 - Legal basis: Urgency ordinance adopted by a 5-0 vote at the April 14, 2026 Oakley City Council meeting (item 6.1), per published minutes; extended by a second urgency ordinance adopted 5-0 on 2026-05-12 (item 5.2). Ordinance No. 5-26, adopted at the same April 14 meeting, is confirmed to be a different, unrelated ordinance (administrative citation-hearing procedures) — not the data center moratorium. The moratorium ordinance was introduced under a placeholder number and its final assigned ordinance number was not stated in the minutes obtained [VERIFY exact assigned ordinance number for the April 14, 2026 urgency ordinance and its May 12, 2026 extension]
- What prompted it: Bridgehead Industrial Project public testimony and removal of data centers from that project; Oakley Municipal Code did not define or regulate data center land uses
- Affected projects: Bridgehead Industrial Project removed data center as a permissible use before approval
- Detailed status: Active under a first extension: the Oakley City Council adopted an urgency ordinance on 2026-05-12 (5-0 vote) extending the original 45-day moratorium by 10 months and 15 days. Under Gov. Code 65858(a), combined with the initial 45-day term this reaches the statutory one-year ceiling from initial adoption (2026-04-14), placing the current expiration at approximately 2027-04-13/14. No permanent data-center zoning ordinance had been adopted by Oakley as of the most recent primary record reviewed (2026-05-12 minutes); a joint Council/Planning Commission work session on data centers was reported by Contra Costa News for 2026-07-21, but that report was not independently corroborated with a primary agenda in this pass.
- Outcome: Staff and Planning Commission to study impacts, gather public input, and draft zoning regulations
