KANSAS CITY, Mo. (AP) — The Kansas City Chiefs plan to explore options that include leaving Arrowhead Stadium after voters in Jackson County, Missouri, soundly rejected a sales tax initiative that would have helped to pay for renovations to the 52-year-old building.

The Chiefs and Royals, whose Kauffman Stadium shares the Truman Sports Complex with the football stadium, have relied on a three-eighths cent sales tax for upkeep. The franchises wanted to extend that tax with the Royals using their share of the money for a new downtown ballpark and the Chiefs envisioning an $800 million renovation of Arrowhead.

More than 58% of voters rejected the sales tax initiative after the campaign was met with criticism from all sides.

“Time is short for us at this point and so we need to see what other options are out there for us,″ Chiefs owner Clark Hunt said Saturday. “When we started on this process three years ago, it felt like we had a very long time — a long runway with about 9 1/2 (years) left on our lease. We’re now down to 6 1/2 and so I do feel very much of a sense of urgency.”
