Florida Statutes Title XXI. Drainage § 298.50. Levy of tax to pay bonds, sinking fund

(1) The board of supervisors in making the annual tax levy, as provided in this chapter, shall take into account the maturing bonds and interest on all bonds, and make provisions in advance for the payment thereof.  In case the proceeds of the original tax levy made under the provisions of s. 298.36 are not sufficient to pay the principal and interest on all bonds issued, then the board of supervisors shall make such additional levies upon the benefits assessed as are necessary for this purpose, and under no circumstances shall any tax levies be made that will in any manner or to any extent impair the security of said bonds or the fund available for the payment of the principal and interest of the same.

(2) A sufficient amount of the drainage tax shall be appropriated by the board of supervisors for the purpose of paying the principal and interest of the said bonds and the same shall, when collected, be preserved in a separate fund for that purpose and no other.  Should said drainage tax prove insufficient for the payment of any bonds issued subsequent to June 1, 1927, additional taxes apportioned to the amounts of said drainage tax may be levied in such amounts as may be necessary for such purposes.
