Indiana Code Title 36. Local Government § 36-9-11.1-18

Sec. 18. (a) Whenever all bonds and other obligations of any particular parking facility have been fully paid and discharged, any surplus in any fund allocated for that purpose reverts to the general fund of the department.  The fund may be used to make up and pay any deficiency that may occur in any other fund for the payment of the bonds and interest issued for any other parking facility under the control of the department.  This use of the general fund may continue until all outstanding bonds on all parking facilities have been fully paid.

(b) The board may also pay to the consolidated city in any year, from any available balance in the general fund of the department, such sum as it considers reasonable and that may be available to compensate the city for its loss of revenue in the annual taxes assessable on property of the estimated current and equivalent value of that acquired for all parking facilities, so long as they remain free of taxes.
