Document Description
San Francisco International Airport (SFO or Airport) proposes improvements to portions of the Airport's existing 12- kilovolt (kV) electrical power distribution systems (proposed project) to maintain reliable electrical power at Airport facilities. The proposed project would replace and upgrade segments of the 12 kV
electric utility cable networks that distribute power to the Airport's terminals and landside buildings. Based on cable testing conducted by SFO in 2023 and 2024, the existing 12 kV cables are approximately 30 years
old, are approaching the end of their serviceable lives, and are prone to failure. As such, SFO is proposing their replacement to maintain primary electrical power and redundancy and to minimize or avert a disruption of power, lighting, and telecommunications service to critical airport operations that may
otherwise result from a failure of the electrical cable system.
The proposed project would involve removing and in-kind replacing electrical cables within an existing 12 kV underground concrete utility duct bank. An approximately 7, 700-foot-long (1.5-mile-tong} set of 12 kV cables would be removed and replaced between Substation BA, with in the Airport's West of Bayshore (WOB)
property, and manhole PD-B660, within a portion of the Airport area east of U.S. Highway 101. These electrical cables ultimately feed into electrical substations on Airport property for distribution to the Airport. Cable sets, each comprising a series of individual cables co-located in an existing Airport utility duct bank,
would be removed from existing manholes and electrical stations and replaced.
Surface construction activities for the proposed project would include clearing vegetation, widening some existing vehicle access roads, and installing new gravel vehicle access roads on a portion of the WOB property. In addition, five permanent access pads surrounding the existing manholes on the WOB property
would be instalted, each totaling approximately 2,100 square feet (30 feet by 70 feet). Construction would also involve dewatering utility vaults accessible via manholes.
