Del. Code tit. 2, § 911

Whenever the governing body of any political subdivision determines that the public interest and the interests of the political subdivision will be served by assisting any other political subdivision in exercising the powers and authority granted by this chapter, the first-mentioned political subdivision is expressly authorized and empowered to furnish such assistance by gift, or lease with or without rental, of real property, by the donation, lease with or without rental, or loan, of personal property, and by the appropriation of moneys, which may be provided for by taxation or the issuance of bonds in the same manner as funds might be provided for the same purposes if the political subdivision were exercising the powers granted in its own behalf.
