More than 17 years after planning began, the long-promised education center next to the historic Sunol Water Temple still has not opened, despite years of redesigns, construction work and a project budget that has grown to more than $32 million. The San Francisco Public Utility Commission says the Alameda Creek Watershed Center is now more than 95% complete, but officials still have not provided an opening date.
The drawn-out project has left a prominent Bay Area landmark largely inaccessible to the public for about a decade. For local residents, the delay has become a symbol of how a high-profile civic project can remain stuck in limbo even after years of public investment and repeated assurances that progress is being made.
Built in 1910, the Sunol Water Temple is a Beaux-Arts-style structure modeled after the Temple of Vesta in Tivoli, Italy. It was created as a monument to the confluence of major Bay Area watersheds and once marked a crucial point in San Francisco’s water system. Beneath the structure, pipelines from Arroyo de la Laguna, Alameda Creek and Pleasanton helped supply about half of San Francisco’s water during the early 20th century. That role changed after the Hetch Hetchy Aqueduct began delivering water to San Francisco in 1934. In 1976, the American Society of Civil Engineers designated the temple a California Historical Engineering Landmark.
The current project traces back to 2009, when the SFPUC proposed building a welcome and education center east of the temple in response to criticism that the agency had provided limited public access to the site’s 36,000 acres. Early cost estimates put the project at roughly $3 million to $4 million. Over time, however, the scope expanded, the concept evolved and the timeline kept slipping.
According to SFPUC officials, the project faced delays at nearly every stage, including excavation, bidding, design revisions and construction. Initial planning documents were rejected by the San Francisco Arts Commission and had to be redone. The project also went through multiple bidding rounds. When the proposal was first released for bids in 2016, officials received only two submissions. One was later withdrawn and the other was rejected. The center was then split from a separate infrastructure improvement project at the Sunol Yard. In 2017, the watershed center was placed on hold because of funding issues.
The facility was later revived, with groundbreaking expected in 2020 and an opening projected for 2023. But construction was halted almost immediately by the COVID-19 pandemic. When work resumed later that year, the agency promoted the project as a $27 million, 10,000-square-foot education hub. Even that target did not hold. The contract amount now stands at $32.86 million, and the center remains unopened.
The delays were not limited to scheduling and budget. The SFPUC said historic winter rainstorms damaged the property and utility hookups, requiring additional repair work. Leaks were also found in the archaeology pit, windows, walls and an 8,000-gallon freshwater aquarium planned for the center.
Project leaders have also pointed to archaeological and cultural work as a major part of the extended timeline. During excavation required under the California Environmental Quality Act, the agency hired a documentary team to record the discovery of Muwekma Ohlone artifacts over a two-year period. About 13,000 artifacts were found, and officials said the exhibit plan was later revised so the center could include reproductions of some of those items as part of a broader interpretive program focused on water, ecology and Muwekma Ohlone history.
That mission has also shaped how the SFPUC describes the project. Agency officials have pushed back on the idea that the building is meant to function as a general community center, saying it is intended specifically as an educational facility tied to the utility’s operations and public history efforts.
Still, residents in Sunol have increasingly tied the unopened center to broader concerns about access, local identity and economic life in town. Some have argued that reopening the area could help reconnect people to an important part of Bay Area history while also drawing visitors to a community that has recently lost central gathering places, including a restaurant and a cafe.
For now, the site remains mostly closed, the project remains unfinished, and the opening date remains unknown. After 17 years of planning, redesign, delay and rising costs, one of the region’s most distinctive historic sites is still waiting for the public to return.
