Voters to weigh in on whether tech billionaires can build new California city

California Forever hopes to build sustainable city in Solano county but company's tactics have been controversial

Voters in northern California will get to weigh in on whether a contentious plan backed by Silicon Valley billionaires to build a new city north of San Francisco can go ahead.

California Forever, the company behind the initiative to build a green city for up to 400,000 people in California farmland, submitted well over the 13,000 valid signatures required to put it on the 5 November ballot, elections officials said on Tuesday.
