Harris County taxpayers may have to inject up to $7 million a year into the Harris County-Houston Sports Authority for the next two years due to a financial crisis sparked by the souring of bonds used to build Minute Maid Park, Reliant Stadium and the Toyota Center.

The authority would have to take $7 million a year now used for stadium maintenance and the expenses of the Harris County Sports and Convention Corporation and spend it on repaying the loans. To make up the difference, Harris County may have to pick up some of those expenses with property tax revenue, a step that some say indirectly violates stadium boosters' promise that taxpayer dollars would not be used to pay for the new venues.
