KANSAS CITY, Mo. — Gov. Mike Kehoe signed a legislative package on Saturday, approved by Missouri lawmakers earlier in the week, that includes hundreds of millions of dollars of financial aid intended to persuade the Chiefs and Royals to remain in the state.

Kehoe, a Republican, had called lawmakers into a special session, and they approved of the package Wednesday.

The Chiefs and Royals currently play at the Truman Sports Complex on the east side of Kansas City, where Arrowhead Stadium and Kauffman Stadium share parking facilities. But their leases with Jackson County, Missouri, expire in January 2031, and the two franchises have been trying to decide the best route forward for the past several years.

Last year, Jackson County voters defeated a sales tax extension that would have helped finance an $800 million renovation of Arrowhead Stadium — the home of the Chiefs — and a $2 billion ballpark district for the Royals in downtown Kansas City.

The slow movement by those on the Missouri side of the state line in supporting the franchises prompted lawmakers in Kansas to authorize bonds for up to 70% of the cost of new stadiums in their state. The Royals have bought a mortgage for property in Kansas, though the team also has continued to pursue other possible sites in Missouri.

The offer from Kansas is scheduled to expire June 30, and both teams have indicated they will hope to have a plan formulated by then. Missouri’s legislation authorizes bonds covering up to 50% of the cost of new or renovated stadiums, plus up to $50 million of tax credits for each stadium and unspecified aid from local governments.

If they choose to stay in Missouri, the Chiefs have floated plans for a $1.15 billion renovation of Arrowhead Stadium. The Royals have insisted all along that they intend to build a replacement for Kauffman Stadium.

The stadium subsidies already were a top concern in Missouri when a deadly tornado struck St. Louis on May 16, causing an estimated $1.6 billion of damage a day after lawmakers had wrapped up work in their annual regular session.

Disaster relief tied to stadium funding had widespread support. On Wednesday, Democratic state Rep. Kimberly-Ann Collins described to lawmakers how she had witnessed the tornado rip the roof off her house and damage her St. Louis neighborhood.

“Homes are crumbled and leveled,” Collins said, adding: “It hurts me to my core to see the families that have worked so hard, the businesses that have worked so hard, to see them ripped apart.”

The Chiefs, in a statement to The Associated Press, described the legislative vote this week as a “significant step forward” that enables the team to continue exploring options to remain in Missouri. The Royals described the legislation as “a very important piece of our decision-making process” but made no site-specific commitment.

“Our focus remains the same: to prioritize the best interests of our team, fans, partners and regional community as we pursue the next generational home for the Kansas City Royals,” the team said in a statement to the AP.

Though they have no specific plans in the works, the St. Louis Cardinals also would be eligible for stadium aid if they undertake a project of at least $500 million. They built their existing Busch Stadium nearly 20 years ago.

“We have the chance to maybe save what is the symbol of this state,” said state Rep. Jim Murphy, a Republican from St. Louis County.

The legislation did face some bipartisan pushback from those who described it as a subsidy for wealthy franchise owners. Others raised concerns that a property tax break for homeowners, which was added in the Senate to gain votes, violates the state constitution by providing different levels of tax relief in various counties while excluding others entirely.

“This bill is unconstitutional, it’s fiscally reckless, it’s morally wrong,” Republican state Rep. Bryant Wolfin said.
