Chase Field

The Arizona Diamondbacks, a 1998 MLB expansion team, play at Chase Field. Located in downtown Phoenix, on a site bounded by Fourth Street to the west, Seventh Street on the north and the Southern Pacific railroad tracks on the south, the ballpark is a state-of-the-art, retractable dome with a natural grass playing surface. The ballpark is owned by the Maricopa County Stadium District, which is governed by the county Board of Supervisors, and operated by an affiliate of the Diamondbacks. The Diamondbacks occupy Chase Field pursuant to the terms of a 30-year license agreement. At the Diamondbacks' option, the lease can be extended for an additional 10 years. The Diamondbacks enjoy priority usage of Chase Field and retain all baseball-related revenues. In addition, the Diamondbacks' affiliate receive a percentage of revenue from non-baseball revenue producing events held in Chase Field. 

Funding for the construction of Chase Field came from an increase in the general sales tax in Maricopa County. The sales tax was increased one-quarter of one cent and became effective April 1, 1995. It is estimated to have generated $70-$75 million annually. The amount of revenue to be raised by the tax was capped at $238 million. The construction manager for the project was Huber, Hunt & Nichols, Inc. The project architect was Ellerbe Becket, Inc., designers of such facilities as Atlanta's Olympic Stadium, the Rose Garden in Portland, Ore., Boston's Fleet Center and the construction of Madison Square Garden.

Eighty-five percent of Chase Field's 48,569 seats are located between the foul poles. There are 69 luxury suites located at the mid-level of Chase Field, as well as six additional party suites. The roof opens to various positions to make sure a proper amount of sunlight hits the natural turf without heating the concrete and metal within the stadium, thus allowing it to cool quickly and efficiently. With the roof in the closed position, the minimum height over the playing surface is 180 feet and the maximum height is 200 feet. The 17,000 square foot, state-of-the-art press facility is designed to accommodate the needs of both the electronic and print media. The Diamondbacks also have state-of-the-art practice facilities, including batting cages and pitching mounds within the stadium itself. A 1,500-car garage is constructed adjacent to the stadium. A parking and traffic circulation study conducted for the Maricopa County Stadium District identified approximately 18,600 parking spaces within a 15-minute walk of the stadium.

Originally called Bank One Ballpark, the stadium's name was changed to Chase Field on September 23, 2005. Bank One Corporation, which owned the naming rights to the stadium, merged with J.P. Morgan Chase & Company in 2004.
