McKINNEY -- In May, voters approved a bond election to help pay for a new high school stadium in McKinney at the price of $63.5 million.

Three months later, the district says the price has gone up to nearly $70 million. The district says the roughly nine-percent increase comes from more expensive concrete and labor than builders planned for.

"From the time they first talked to contractors about price to when they got a firm bid the price went up 50 percent," said Cody Cunningham, a spokesman for McKinney ISD.

Cunningham says district leaders had a decision, either change the stadium plans or build the original model.

"We decided this is something that we'll be using for 50 or 60 years so we want to do it right," Cunningham said.

McKinney ISD says it will get the additional $7 million from money left over from previous bonds. The district adds it will be able to pay for the increased cost while still dropping the debt tax by five cents.

Crews are scheduled to break ground on the stadium in September and the stadium should be finished by the end of 2017.
