     (1) The legislative authority of a county with a population of one million five hundred thousand or more may impose a special stadium sales and use tax upon the retail sale or use within the county by restaurants, taverns, and bars of food and beverages that are taxable by the state under chapters 82.08 and 82.12 RCW. The rate of the tax shall not exceed five-tenths of one percent of the selling price in the case of a sales tax, or value of the article used in the case of a use tax.

     (((b))) (ii) If the revenue from the taxes imposed under this section exceeds the amount needed for the purposes in (a)(i) of this subsection in any year, the excess shall be placed in a contingency fund which may only be used to pay unanticipated capital costs on the baseball stadium, excluding any cost overruns on initial construction.
     (b) After the bonds issued for the construction of the baseball stadium are retired, the revenue from the taxes imposed under the authority of this section must be applied as set forth in subsection (6) of this section.
     (4) The proceeds of any bonds issued for the baseball stadium shall be provided to the district.
     (5) As used in this section, "baseball stadium" means "baseball stadium" as defined in RCW 82.14.0485.
     (6) ((The taxes imposed under this section shall expire when the bonds issued for the construction of the baseball stadium are retired, but not later than twenty years after the taxes are first collected)) (a) After the bonds issued for the construction of the baseball stadium are retired, at the time the conditions in (b) of this subsection are met, the largest city in the county shall retain the portion of the taxes in subsections (1) and (2) of this section from sales within the city.
     (b) In order to retain the revenue in (a) of this subsection, on or before August 18, 2013, the largest city in the county must have entered into a binding and legally enforceable contractual commitment with a prospective basketball lessee to (i) lease a multipurpose public arena within the city and (ii) pay at least one hundred fifty million dollars, in 2008 dollars adjusted for inflation annually using the engineering news record twenty-city construction cost index, towards the cost of the project to improve a multipurpose public arena within the city.
     (c) This subsection is only applicable until the time that bonds are paid off for the purposes of (b) of this subsection.
