"At any of our hit shows, we turn away literally thousands of people who cannot get in," because tickets are sold out, he said.
Another impetus for the move is the exposure and accessibility with the Sandy facility. Located just east of Interstate 15, Dietlein envisions large marquees drawing in visitors, who mostly travel from the south end of the Salt Lake Valley.
"Being right on the freeway is tremendous," he said. "There won't be anyone in the state who doesn't know where Hale Centre Theatre is and what's playing."
Construction will begin in September. The smaller stage is set to open in January 2017, and the full project will be completed around May that year. The state also will add a new underpass to the freeway exit on 10600 South to serve the theater's patrons.
To pay for the new space, Sandy has taken out a $42 million bond, which will be repaid by Hale over time. The city will own the theater until the bond is paid off, in about 27 years, when Hale will have a chance to take over the space.
Sandy Mayor Tom Dolan said it's a risk he feels comfortable with. "We're confident that this will work," he said. "We've worked for a long time to get through this."
Hale had previously made arrangements with Sandy to house the theater in February 2013, but the plans fell through. Dolan said he was "frustrated" at the time, but now believes the stage is better set for the new facility. He calls Hale a "key piece" of the puzzle he's putting together that involves revitalizing Sandy with a new city plaza, more high-density housing, a renovated South Towne Mall and, now, a place for the arts.
The theater will take up about 130,000 square feet on an 11.5-acre parcel to soon include office spaces and a parking garage that will serve theater-goers in the evenings.
Dietlein said board members have discussed moving Hale for the past six years. Originally, 15 communities and cities were in the running, including South Jordan – the last city to be taken off the list in June 2014. The group also considered staying in West Valley City, the state's second largest city, but decided against that.
"The opportunity that presented itself with Sandy city just simply made a lot more sense for us than any other location that we looked at," he said.
West Valley City Manager Wayne Pyle said the city has known of Hale's departure for some time, and is looking at proposals for different ways to use the city-owned facility.
"We've got some good prospects," he said.
All of the current bids under consideration are theater-related, and it will take several months before the city chooses a new partner.
West Valley City Mayor Ron Bigelow could not immediately be reached for comment.
