To increase the security and marketability of redevelopment bonds or notes, the local government may:
(1) Create a lien for the benefit of the bondholders upon any public improvements or public works financed by the bonds; or
(2) Make such covenants and do any and all such actions, not inconsistent with the Arkansas Constitution, which may be necessary or convenient or desirable in order to additionally secure the bonds or notes, or which tend to make the bonds or notes more marketable according to the best judgment of the local governing body.
