Visitors to Disney's California parks could one day walk through the snow-covered hamlet of Arendelle from "Frozen" or the bustling, critter-filled metropolis of "Zootopia" under a park expansion plan approved by the Anaheim City Council.

Disney would spend at least $1.9 billion over the next decade to transform its 490-acre (488-hectare) campus in densely-populated Southern California. It would be the biggest expansion of Disney's Southern California theme parks in decades, aiming to create more immersive experiences for guests. Disney would also be required to spend tens of millions of dollars on street improvements, affordable housing and other infrastructure in the city.
