The mayor also said the owners of the Kings have agreed to fully disclose their financial information so the David Taylor/ICON Venue Group can build a complete feasbility study.
The study will be presented to the Sacramento City Council on May 26.
It's assumed the study will have a funding gap, which Johnson said will necesitate a public and private partnership and will include the Maloofs.
"They're going to have to participate by this public-private partnership. They're going to have to put dollars in some shape or form. What that is or how much we don't know yet. But they're going to have to participate," said Johnson.
