Bexar County Commissioners Court on Tuesday agreed to call a city-county election on “expansion expenses” if Major League Soccer offers the Alamo City a franchise that’s being pursued by the Spurs organization.

The county officials voted unanimously to split with the city the $18 million cost of purchasing the Northeast Side field from Gordon Hartman’s S.O.A.R. organization.

As part of the pact, Spurs Sports & Entertainment would give Hartman another $3 million for a 20-year lease.

Additionally, the Spurs would provide $1 million for improvements to the field — matched by $500,000 each from the city and county.

No cost was estimated yet for possible expansion expenses.

The city, which supports the MLS initiative, takes up the same agreement on Thursday. Starting in six years, its clawback provisions require repayments to the city and county if no MLS franchise is secured.

“We are absolutely ready to take the next steps to get this thing finalized,” said Spurs vice president Bobby Perez. One of the next steps, he said, is securing a United Soccer League franchise to start playing next year.

“Our goal is to have our home opener on March 24 at Toyota Field,” Perez said.

The fate of the Scorpions, the local NASL franchise based at Toyota Field, hasn’t been determined, but Hartman said discussions with the league start Friday.

“To say that this is a tight timeline is an understatement,” Hartman said.
