Del. Code tit. 22 § 513
When any authority shall have finally paid and discharged all bonds, which, together with the interest due thereon, shall have been secured by a pledge of any of the revenues or receipts of a project, it may, subject to any agreements concerning the operation or disposition of such projects, convey such project to the city creating the authority. When any authority shall have finally paid and discharged all bonds issued and outstanding and the interest due thereon and settled all other claims which may be outstanding against it, it may convey all its property to the city and terminate its existence. A certificate requesting termination of the existence of the authority shall be filed in the office of the Secretary of State. If the certificate is approved by the city creating the authority by its ordinance or ordinances, the Secretary shall note the termination of existence on the record of incorporation and return the certificate with the Secretary's approval shown thereon to the board, which shall cause the same to be recorded in the office of the recorder of deeds of the county. Thereupon, the property of the authority shall pass to the city and the authority shall cease to exist.
