Background
On June 22, 2026, the City Council adopted Ordinance No. O2M26-4863 which included a ban on data centers. More specifically, the amendment includes a definition of data centers, and then lists them as prohibited in the employment zoning districts and does not list them as a permitted use in any other zone in the City. The City Council has placed this measure before the voters so that the electorate may decide whether to affirm that ban by adopting it as a voter-approved ordinance.
Proposal
If approved, Measure DB would amend Alhambra Municipal Code Section 23.43.050 to add a sentence at the end of the current definition of “Data Center” as follows (added language shown as underlined): “Data Centers. Facilities used primarily for analyzing, processing, storing, converting, transmitting, distributing, and managing electronic data for on-site or off-site use. These facilities typically house computer, network, and telecommunication equipment, systems, servers, appliances, and other associated components related to electronic data operations. This classification excludes data facilities that are incidental to another primary use and that are strictly for the purposes of supporting the on-site operations of the primary use. Data Centers are prohibited in all zones of the City.”
