This was already planned, but Disney wasted no time pushing this announcement in Rhonda Santis' eye. Via the L.A. Times:

As Walt Disney Co. continues to pitch its 30-year theme park expansion plan to Anaheim, the company released new data on just what’s in it for the city.

For every $1 billion Disney invests to redevelop and update Disneyland Resort, the project will generate $253 million annually in economic output, $15 million in tax revenue, and 2,292 jobs, according to an economic analysis the company commissioned from the Woods Center for Economic Analysis & Forecasting at Cal State Fullerton. The analysis also laid out additional economic benefits from the four-year construction phase.

[...] Disney unveiled the analysis Wednesday at an OC Forum event for city and business leaders at Disney’s Grand Californian Hotel, part of a broader months-long pitch process for its DisneylandForward initiative that also includes a series of pop-up “community coffees” with residents at local public parks.

Disney still has to get approval for mixed-use land development from Anaheim. Seems likely, though, since Gov. Newsom is pushing for Disney to spend that Florida money in California.
