Del. Code tit. 22 § 508
The authority may acquire by purchase or eminent domain proceedings either the fee or such rights, title, interest or easement in such lands as the authority deems necessary for any of the purposes mentioned in this chapter. When acquiring property or property rights the authority shall, in arriving at a fair and reasonable price, consider the fair market value as required by Chapter 61 of Title 10. Relocation shall be paid according to the terms set forth in Chapter 93 of Title 29. The following shall not be taken under the right of eminent domain: Property devoted to a public use, property of a public service company, property used for burial purposes, place of public worship in a municipality whose population is greater than 50,000 people, property used as a facility or facilities for the parking of motor vehicles, unless the total square footage to be utilized for the parking of motor vehicles in the total proposed project which the eminent domain proceedings concern (including square footage that may be provided on levels other than the ground level) shall be at least twice the total square footage being utilized at the time of taking for the parking of motor vehicles in the facility or facilities so taken or in a municipality whose population is 50,000 people or less, property used as a facility or facilities for parking of motor vehicles unless said property has been leased by the municipality or authority and used as a parking facility by said lessee within the preceding 3 years. The right of eminent domain shall be exercised by the authority in the manner provided by Chapter 61 of Title 10.
The right of eminent domain conferred by this section may be exercised only within the city.
Court proceedings necessary to acquire property or property rights for purposes of this chapter shall take precedence over all causes not involving the public interest in all courts to the end that the provision of parking facilities be expedited.
Any municipality establishing an authority under this chapter may, under such terms and conditions as it may deem appropriate, provide for and pay to such authority such sum or sums of money necessary to acquire, in whole or in part, the lands upon which such authority may undertake to erect a parking facility as provided in this section, or such sum or sums of money necessary to acquire or construct, in whole or in part, a parking facility or facilities as provided in this section, or such sum or sums of money necessary to pay operating expenses of the authority and debt service on outstanding bonds of the authority, or to make payments into a reserve fund for the payment of the principal of and interest on indebtedness of the authority as may be provided by any resolution of the authority authorizing the issuance of its revenue bonds or by any trust indenture securing its revenue bonds. The municipality, for the purpose of providing such sum or sums of money, may issue its general obligation bonds secured by the faith and credit of the municipality payable from unlimited ad valorem taxes on all of the real estate in the municipality subject to taxation or levy ad valorem taxes on real estate subject to taxation, unlimited as to rate or amount. In addition to the issuance of its general obligation bonds and levy of taxes as provided above, a municipality may guarantee bonds of the authority issued pursuant to § 505 of this title by pledging its full faith and credit to the payment of the principal of and interest on such revenue bonds. The aggregate amount of general obligation bonds issued by a municipality under this provision and the indebtedness so guaranteed and taxes levied shall be in addition to and not within the limitations of any existing statutory debt or tax limitation of the municipality. Any agreement by the municipality to guarantee the revenue bonds of the authority or to maintain a reserve fund or to pay debt service or operating expenses of the authority may be made a part of any contract with holders of revenue bonds of the authority and may be pledged by the authority to the payment of such revenue bonds. The enforcement or performance of such guaranty may include resort to the power of the municipality to tax real estate subject to taxation, with no limit as to rate or amount, or to any other moneys of the municipality available for such purpose.
