The 2025 Revenue Bonds funded improvements to the McKinney National Airport (the "Airport") (e.g., passenger terminal facilities and other airport facilities, streets and roads, taxiways, aprons, and other infrastructure related to the Airport). The Attorney General approved the 2025 Revenue Bonds on April 10, 2025.

That same day, the City approved MCDC's proposed bond issuance as required by the Development Corporation Act. The 2026 Refunding Bonds will be issued in the amount of $30 million and will be used for the purpose of refunding the outstanding 2025 Revenue Bonds. The 2026 Refunding Bonds are secured by and payable from the revenues that MCDC receives from the City through the City's levy of a voter-approved sales and use tax. The 2026 Refunding Bonds will not be paid from any property taxes to be raised by the City. Among other things, the Petition seeks declarations that (i) MCDC has the authority, on the terms set out herein, to issue the 2026 Refunding Bonds; (ii) that MCDC was and is authorized to have taken each public security authorization relating to the 2026 Refunding Bonds; (iii) that the City was and is authorized to have taken each public security authorization relating to the 2026 Refunding Bonds; (iv) that each public security authorization and expenditure of money relating to the 2026 Refunding Bonds was legal; and (v) that MCDC properly introduced and enacted the 2026 Refunding Bonds pursuant to the laws of the State of Texas and the City of McKinney Charter.
