The Round Valley Ensphere is a wood dome stadium in Eagar, Arizona, USA.[2] It is owned by Round Valley High School and the Round Valley Unified School District. It is the only domed high school football stadium in the United States.[3] Opened in 1991–92[4] at a cost of US$11 million, the venue seats 5,500 persons for American football[5] and 9,000 for basketball and volleyball.[2] The dome encloses a floor area of 189,000 square feet (17,600 m2).
History
In 1987, a $12 million bond for the dome and repairs was floated and passed after it was found that Tucson Electric Power, which operates a generating station in the area, would have to pay for $11 million of it. (Since the utility generates 90% of the property values in the area, it pays 90% of the property taxes.) TEP, at the time facing financial issues, sued to block construction, but trial and appellate courts rejected the lawsuit.[2]
Construction began in the summer of 1990. It was forced to stop for three months for reinspection when two workers were hit by wooden beams and fell 75 feet to their deaths.[2]
The dome held its first football match on October 11, 1991, featuring the Payson High School Longhorns.[2]
The venue was closed in 2015 due to water damage[6] and will remain closed for at least a year.[7] The water damage was caused when heavy rains brought water into the building through the exterior doors.[8] The damage to the synthetic turf in the facility produced elevated levels of mercury vapor, which require the facility to undergo professional remediation.
Structure
The Ensphere encloses 8,000,000 cubic feet (230,000 m3) of space and was the first fully day-lighted dome of its kind, allowing light and heat to enter.[9]
Uses
School
In addition to football, the facility is used for basketball and track and field as well.
Non-school
The dome is also used for non-school events, such as a car show (). In 2002, as a result of the Rodeo-Chediski fire, the second largest in Arizona history, the Dome was used as a shelter. It took in 9,800 evacuees, tripling Eagar's population overnight, and President George W. Bush visited the shelter.[10][11] The absorption of so many people almost caused the town's sewage system to be overloaded.
