The proposal, which would also require approval by the U.S. Congress, would split California into six new states called Jefferson, North California, Silicon Valley, Central California, West California and South California.
Under the plan, Los Angeles and Santa Barbara would be part of "West California," while San Francisco and San Jose would be in "Silicon Valley."
"California, as it is, is ungovernable," proponent Tim Draper, founder of the venture capital firm Draper Fisher Jurvetson, said in a statement released by his office on Thursday.
"It is more and more difficult for Sacramento to keep up with the social issues from the various regions of California. With six Californias, people will be closer to their state governments and states can get a refresh," Draper said.
California Secretary of State Debra Bowen said on Tuesday that the proposal needs the signatures of 807,615 registered voters by July 14 to qualify as a ballot measure in November's elections.
