The terms of the proposed agreement between the city and Big Sports Properties places the burden of $4 million in infrastructure improvements on the developer.

Geisel emphasized that no city money will be used in the development and operation of the dome complex.

The city director said discussions are underway to work out terms of a 50-year agreement on the 30-acre tract for lease payments that could ultimately deposit $250,000 annually in Chesterfield coffers.

“Chesterfield would have no expenses — this would be a revenue generator for us,” Geisel said.

Big Sports Properties and Chesterfield have until mid-January to finalize the lease details.

The city on Sept. 29 also signed an agreement to spend $2 million to buy 22 acres adjacent to the dome complex.

That property is to be developed as a separate outdoor facility to accommodate baseball, softball and sand volleyball games.

This is not the first time developers have envisioned a sports complex rising on the real estate where Chesterfield Dome Complex and the adjacent city project may soon take shape next to Highway 40.
