The Utah Jazz may have to wait until October to know details of a possible new arena downtown, government officials said Friday.

But the decision on whether to build a facility will likely be made by summer's end.Salt Lake County officials are hurrying to set up committees of government and business leaders to study whether a 25,000-seat arena should be built and how it could be financed. They are hurrying because of the belief the Jazz may move to a new stadium in the suburbs unless a decision is made soon.

Larry Meyer, administrative assistant to Commission Chairman Bart Barker, said the committees will decide first whether the project is realistic, then they will take extra time to work on details.

By October, the county should be ready to decide how to solicit bids for building the project, he said.
