, the year the Diamondbacks debuted as an
expansion team. Chase Field was the first stadium built in the United States with a
retractable roof over a natural-grass playing surface.
History
The park was built during a wave of new, baseball-only parks in the 1990s. Although nearly all of these parks were open-air, it was taken for granted that a domed stadium was a must for a major-league team to be a viable venture in the Phoenix area. Phoenix is by far the hottest major city in North America; the average high temperature during baseball's regular season is , and game-time temperatures well above are very common during the summer.
Stadium funding controversy
In the spring of 1994, the
Maricopa County Board of Supervisors approved a quarter percentage point increase in the county sales tax to pay for their portion of the stadium funding. This came about at a time that the county itself was facing huge budget deficits and lack of funding for other services. The sales tax being levied was very unpopular with local citizens, who were not allowed to vote on the issue of funding a baseball stadium with general sales tax revenue (usage of public subsidies for stadium projects was actually prohibited by a 1989 referendum). The issue was so controversial and divisive that in August 1997, Maricopa County Supervisor Mary Rose Wilcox was shot and injured while leaving a county board meeting by Larry Naman, a homeless man, who attempted to argue in court that her support for the tax justified his attack. In May 1998, Naman was found guilty of attempted first-degree murder.
Costs for the stadium were originally estimated at $279 million in 1995, but cost overruns (in part because of rising prices for steel and other materials) pushed the final price to $364 million. As part of the original stadium deal, the Diamondbacks were responsible for all construction costs above $253 million. These extra expenses, combined with the Diamondbacks and their fellow expansion franchise, the
Tampa Bay Devil Rays, not being allowed to share in the national MLB revenue for their first 5 years of operations, left the Diamondbacks in a less-than-desirable financial situation, which would come back to haunt team founder and managing partner

was the first player to hit a home run into the pool.
Besides baseball, the pool has been used by Monster Jam's Jim Koehler to continue his tradition of swimming after Freestyle. The ballpark also featured a dirt strip between
home plate and the
pitcher's mound. This dirt strip, sometimes known as the "keyhole", was very common in old-time ballparks up to 1938. The dirt strip was removed when synthetic turf was installed in 2019; today,
Comerica Park is the only park to still have this.
The park's foul territory is somewhat larger than is the case for most ballparks built in the 1990s. With 80% of the seats in foul territory, the upper deck is one of the highest in the majors. The park's suites are tucked far under the third deck, which keeps the upper deck closer to the action, with the exception of their Dugout Suites which sit next to the home and visitor's dugouts.
Before the
2008 season began, a brand new
HD scoreboard was installed beyond center field, replacing the original. The new scoreboard is high and wide and it cost $14 million. It is the fifth largest HD screen in Major League Baseball behind
Kauffman Stadium. The screen at Kauffman is larger by overall area and is square in shape but Chase Field's screen is larger by length and is rectangular.
Premium seating includes 4,400 club seats, 57 suites, 6 party suites, Executive suite, batters box suite, two dugout suites, and a swimming pool.
The
Diamondbacks and
St. Louis Cardinals game on September 24, 2019 became the longest game in Chase Field's history. The game lasted six hours and 53 minutes in 19 innings.
On October 12, 2018, the Diamondbacks announced that they would be replacing their natural grass surface with a synthetic surface from Shaw Sports Turf for the 2019 season. In 2019, leaked images of a potential new stadium by architectural firm MEIS Architects had a brief life online before being removed shortly thereafter by the firm.
Naming rights
The stadium was originally called Bank One Ballpark when
Bank One of Chicago, Illinois, purchased naming rights for $100 million over 30 years. After Bank One merged with New York-based
JPMorgan Chase & Co. in 2005, Chase assumed the commitment to the naming deal and the stadium's name was changed to Chase Field.
Notable events
The stadium also hosts occasional concerts and international soccer games. For football and soccer, the field is set up with the end lines perpendicular to the third-base line and temporary bleachers added on the east side.

Roof and cooling system

Chase Field's roof is opened or closed depending on the game-time temperature. Even when the roof is closed, the park's windows allow enough sunlight to play in true daylight without overheating the stadium. The roof takes about 4½ minutes to open or close at a cost of $2–$3.
While the ballpark had a grass surface, the roof would be kept open to expose the playing surface to sunlight. When necessary, it would be closed three hours before game time using two 200-horsepower motors triggered from a control room in the upper deck above left-center field.

system then dropped the temperature inside the park to about 78 °F (25.5 °C) by the time the gates open. The chilled water system, which has cooling power equivalent to 2,500 homes of , also serves more than 30 buildings in downtown Phoenix.
The cooling plant, located in a separate building right outside the ballpark, freezes water overnight to reduce daytime electricity demand.
Originally, the HVAC system didn't cool above row 25 of the upper level, exposing fans in the higher rows to the brunt of Phoenix' oppressive summer heat. Subsequent improvements kept virtually all of the facility in air-conditioned comfort.
Following the introduction of a synthetic playing surface, the roof has been kept closed at most times and is now opened only on game days when weather permits, greatly reducing the facility's demand on the HVAC system.
