Committee recommends acceptance of Mission Bay South public infrastructure after review of subsidence safeguards
Summary
The Board of Supervisors’ Land Use & Transportation Committee voted to send an ordinance accepting Mission Bay South streets, utilities and a stormwater pump station to the full Board following staff presentations that described geotechnical settlement measures and ongoing protections for the city.
The Land Use and Transportation Committee voted Oct. 19 to send to the full San Francisco Board of Supervisors an ordinance accepting public infrastructure improvements in Mission Bay South for city maintenance and liability.
Chair Supervisor Aaron Peskin said follow‑up answers to questions from a September hearing satisfied him and invited the project team to brief the committee. OCII representatives reported the infrastructure has been in use for years, was designed and permitted to city standards, and monitored by Public Works and the Public Utilities Commission. Public Works senior staff said geotechnical studies by Treadwell & Rollo identified bay mud and predicted settlement; engineers designed utilities and pavements to settle together and required flexible laterals and building interfaces to accommodate movement.
John Thomas, Public Works, told the committee the settlement to date has been uniform across blocks and that inspections and monitoring show no breaks in utilities or mains. Public Works issued a determination of completion and Planning Department staff determined the improvements are consistent with the city’s General Plan and planning code section 101.1. The ordinance would accept irrevocable offers of dedication, set sidewalk and right‑of‑way widths, and establish street grades for the public record.
No members of the public spoke on the item. Chair Peskin moved to forward the ordinance as a committee report; a roll call recorded three 'ayes' and the item will proceed to the Board for final action.
The acceptance will transfer long‑term maintenance responsibility to city departments while OCII and developers retain obligations to address future repair work estimated to be performed at cost, including repairs tied to future subsidence.
