Indiana Code Title 36. Local Government § 36-9-11-8

Sec. 8. (a) A municipality may acquire the property required for parking facilities by gift, lease, purchase, the exercise of the power of eminent domain, or any combination of these methods.  A municipality may also acquire air rights above real property, for facilities above that property, without also acquiring that property.

(b) The municipal works board may, at any time, obtain an option for the purchase of the land required for parking facilities, or may enter into a contract for the purchase of that land upon the terms and conditions it considers best.  However, the options or contracts are subject to the final action of the works board under section 5 of this chapter, and to the condition that the land may be paid for only out of money made available to the board for that purpose under this chapter.

(c) In acquiring property for parking facilities by the exercise of the power of eminent domain, a municipality shall proceed under the statutes governing the exercise of the power of eminent domain by the works board of a municipality of its class, or under any applicable general statute.  However, property may not be acquired by a city under this subsection until it is approved as a suitable location for a parking facility by the legislative body.

(d) The works board may use for parking facilities any land that was previously acquired by the municipality and is not needed for other purposes.  In a city, however, such an action must be approved by the legislative body.
