Whenever there is not a sufficient cash balance in said local improvement guarantee fund at any time to pay any and all warrants, together with interest thereon, drawn against said fund, the city council may replenish said local improvement guarantee fund by transferring or appropriating to it, monies from the general fund of the city or other available sources as may be determined by the city council, subject, however, to the limitations prescribed in this chapter. Warrants drawing interest as provided in this chapter may be issued against said local improvement guarantee fund to meet any financial liability against it; but at the time of making its next annual tax levy, the city shall provide for the levy of a sum sufficient with other resources of the guarantee fund to pay warrants so issued and outstanding, the tax for this purpose not to exceed one mill in any one year.
