The measure backed by Tim Draper has hit almost 420,000 valid or projected to be valid signatures in the random sample, topping the 365,000 needed to qualify for the November ballot.
But even if the plan is approved at the ballot box, Congress would still have the final say on whether it can go ahead.
Plenty of ideas about splintering California into smaller states have popped up - including an effort by rural, more conservative northern counties that seek to break away to become "State of Jefferson". The new California state along the coast from the counties of Monterey to Los Angeles would be a net importer of water from the proposed Northern California and Southern California.
Keeping the name California would be a group of six counties centered around Los Angeles, with a total population of 12.3 million people. Southern California will consist of a number of counties in the state's Central Valley, Inland Empire, and southern coastal regions, including Fresno, San Bernardino, Orange, and San Diego Counties.
It's not just California that would feel the effects of such a change.
"If some people feel that their government isn't working for them - and I know a lot of people in very poor regions feel that the status quo is not working for them - this would be an opportunity for them to easily move to another state without leaving the handsome weather we get here", he said. With its 55 electors in the Electoral College, California has always been a stronghold for the Democratic Party.
Although California as it exists today is heavily Democratic, one of the new Californias might not be. The state of Northern California would contain 40 counties, including those in the Sacramento and Bay areas. Democratic voters now edge out Republicans in the 12 counties, but not by much.
Silicon Valley venture capitalist Tim Draper proposes turning California into three states.
Nevertheless, Draper has argued it's necessary to fix the state government.
Despite the odds, the "Cal-3" initiative is moving forward, and it will likely to be subject to an interesting debate among scholars in the coming months. Southern California depends more on manufacturing and wholesale, and has a median household income of $45,000. Then it would reach the US Congress.
