This is how the billionaires planning a new city near San Francisco imagine their utopia could look

• The company that wants to build a new city in northern California posted renderings online. 
• California Forever posted CGIs of the "walkable community" on its website.

Renderings for a new city in California depict a "walkable community" featuring solar farms, local jobs and trade schools.  

California Forever, the parent company of Flannery Associates, launched its website and shared first images of what the city in Solano County could look like if it goes ahead.

The computer-generated illustrations show people kayaking, fishing, cycling and dining outdoors, as well as installing solar panels. 

Five design principles of the city were disclosed on the website, including creating local jobs for Solano residents, walkable neighborhoods and building a large solar farm. However, details of just how California Forever intends to go about creating its utopian city are sparse.

The company's plans, backed by Silicon Valley elites, have been quietly put in motion over six years as it purchased 52,000 acres of farmland worth $800 million in the county.

The scheme has drawn criticism from local officials, including Catherine Moy, the mayor of Solano Fairfield, who hit out at the way it's gone about its plans. Congressman John Garamendi told NBC Bay Area that the company had been "engaged in despicable, secretive, terrible practices".

California Forever said operating in stealth mode and keeping its plans under wraps was "the only way to avoid creating a rush of reckless short-term land speculation."

It added: "To date, our company has been quiet about our activities. This has, understandably, created interest, concern, and speculation. Now that we're no longer limited by confidentiality, we are eager to begin a conversation about the future of Solano county."

It now has to gain approval from Solano County residents, 2,000 of which have already been surveyed, California Forever's website states.

California Forever didn't immediately respond to a request for comment from Insider, made outside normal working hours.
