Equinix Data Centers (SV-12, SV-13, & SV-14)

SP15-031 – Equinix Data Centers (SV-12, SV-13, and SV-14)

Special Use Permit to allow removal of nine ordinance-size trees and four non-ordinance size trees on-site, three off-site trees, and the construction of three data center buildings totaling 579,000 square feet on 18.56-gross acre site.

Santa Teresa Substation

The Initial Study also evaluates the construction of a new electrical substation to serve the data centers. This substation is proposed at the existing Pacific Gas and Electric (PG&E) Edenvale Service Center, located at 6402 Santa Teresa Boulevard and northwest of the data centers site. The proposed substation site would be approximately 1.9 acres and bound by an existing paved storage area to the south, undeveloped land to the east, VTA light-rail tracks to the north, and undeveloped land to the east. The substation portion of the project would include installation of four tubular steel poles and conductors that would provide a connection to the existing 115 kV Metcalf-Edenvale transmission line to the west. Two electrical 21 kV distribution feeders would also be routed underground along Via Del Oro to connect the proposed substation site with the proposed data center site.


Data Centers: undeveloped land to the south of Via Del Oro between San Ignacio Avenue and Great Oaks Boulevard (APNs 706-02-053 and 706-02-054, and portions of 706-02-055 and 706-02-056). Electrical Substation: 6402 Santa Teresa Boulevard (APN 706-03-016).

The City has performed environmental review on the project. Environmental review examines the nature and extent of any adverse effects on the environment that could occur if a project is approved and implemented. Based on the review, the City has prepared a draft Mitigated Negative Declaration (MND) for this project. An MND is a statement by the City that the project will not have a significant effect on the environment if protective measures (mitigation measures) are included in the project.

The public comment period for this draft Mitigated Negative Declaration begins on Monday, December 12, 2016, and ends on Wednesday, January 18, 2017.
