Plans for an ambitious $800 million city project by Silicon Valley billionaires in Solano County, California, have been halted after a report estimated potential taxpayer costs of $50 billion for infrastructure. The company behind the project, California Forever, has decided to withdraw a measure from the upcoming November ballot that would allow voters to consider zoning changes, opting instead for a two-year environmental review. Despite ambitious claims of creating housing for 400,000 residents and generating 15,000 jobs, the initiative has faced significant local opposition and skepticism regarding its feasibility. Critics have accused the project's backers, including notable tech figures, of using aggressive tactics to acquire land and push the plan forward. Jan Sramek, CEO of California Forever, stated that they aim to resubmit their proposal in 2026, but local leaders remain doubtful about the project’s future viability. The decision marks a significant setback for tech investors who have spent $900 million acquiring land for the proposed city.
