Developer Jerry Kamilos has asked state fair board officials to give him 30 more days to develop elements of an arena land swap proposal that would relocate the fairgrounds to Natomas, a state fair official said Tuesday.

Kamilos, who is proposing to build a downtown arena, asked the California Exposition and State Fair board late last week to postpone releasing a consultant's report on his proposal to sell Cal Expo and swap that fairground site for the Arco Arena site until Sept. 17, said Cal Expo Deputy General Manager Brian May.

Cal Expo officials had planned to release the report Tuesday. Kamilos is requesting that they consider additional information before finalizing the report. 

The developers need more time to provide a more detailed cost estimate and information on how the state fairgrounds would fit in Natomas, as well as on transportation and circulation plans, minimizing impacts on neighbors, public forums and other needs, Kamilos said.

"It made more sense to make sure the concepts are fully defined and analyzed, so the board and public has the most up-to-date and accurate information," he said.
