The board of county commissioners does hereby covenant with the owners of the bonds
that it will not enact any ordinance which will repeal, impair or amend in any manner
the rights of such owners or the security for the funds which may be pledged to the
payment of bonds issued by the county pursuant to the provisions of this division
or for the payment of bonds issued by a nonprofit corporation in connection with any
lease or lease-purchase arrangement authorized by this division. Also, the board of
county commissioners may further covenant with the owners as it deems appropriate,
including covenants to cause certain of the county's non-ad valorem fund revenues
to be placed directly in a lawful county depository.
