Planning Commission approves AT&Tmonopole at 350 Amber Drive over residents' objections, 4-3

The Planning Commission narrowly approved AT&T's request to install a 104-foot telecommunications monopole and associated equipment at 350 Amber Drive, sited in the San Francisco Police Academy parking area, by a 4-3 vote on Thursday.

Planning staff told the commission the site is a Planning Code "preference 1" location (publicly owned structure) and that a shadow study showed effectively negligible additional shadowing on adjacent Recreation and Park properties (George Christopher Playground and Glen Canyon Park). The Recreation and Park Commission had earlier recommended that the net new shadow would not be adverse. The project requires conditional-use authorization because the facility would exceed the 40-foot threshold of the zoning district.

AT&T representatives said the monopole was needed to fill long-identified coverage gaps for customers and public-safety users, including FirstNet, the nationwide public-safety network. The carrier presented maps and propagation modeling that showed a large coverage deficit in the Glen ParkMira Loma area that the proposed site would address.

Opposition speakers, including residents of houses that overlook Glen Canyon and a coalition of environmental and community groups, urged denial. They raised multiple concerns: the monopole's proximity to a densely used park and playground, the site's geotechnical history (the area contains deep landfill and previous slope instability), fire and public-safety risks linked to the site's diesel backup generator, potential emissions, and the aesthetic harm of a tree-height monopole visible from canyon trails and adjacent homes. Several residents also pointed to the neighborhoodalready burdened with historic contamination and high respiratory illness ratesand asked for alternative, less intrusive coverage solutions such as co-locating on rooftops or smaller-cell installations.

Commissioners split over whether the demonstrated coverage need and the site's status as a preference-1 public site outweighed the visual and safety concerns raised by speakers. A motion to continue the item failed; a motion to deny (intent to disapprove) also failed. A motion to approve passed 4-3 with Commissioners Campbell, McGarry, Braun and President Soh voting yes; Commissioners Williams, Imperial and Moore voted no.

Conditions attached to the approval require standard planning mitigations and an eight-foot perimeter fence around ground equipment; AT&T also confirmed 24/7 video monitoring and a helpline on site. Planning staff noted that federal law (FCC rules) preempts local authorities on RF-safety questions, and the commissionconsistent with precedentconsidered land-use and shadow effects and the location preferences identified in the city's wireless-siting guidelines.

Why this matters: The decision resolves a long-standing local coverage gap but underscores the tension between wireless infrastructure and community concerns about visual impacts, geotechnical safety, and cumulative environmental burdens in neighborhoods already carrying heavy industrial and infrastructure uses. The vote was narrow, and opponents said they would continue to press for alternative solutions if the carrier seeks to expand the network.
