The County of Loudoun shall not pledge its full faith and credit or any moral obligation toward repayment of the principal and interest on any debt or other obligations of a community development authority. An ordinance creating a community development authority shall contain a provision that the County of Loudoun has no moral or legal obligation to support the debt of the district, but may provide that the Board of Supervisors retains the authority and ability to act to protect the County of Loudoun's credit.
