California Code, Streets and Highways Code - SHC § 8808

The city shall have the right to advance and pay any other taxes wherever necessary to protect its interest in property against which there is a delinquent assessment. It may also, at its discretion, temporarily transfer moneys into the redemption fund from other funds in which the moneys are not immediately needed. If the city has determined to obligate itself to use available funds to cure any deficiency in the redemption fund pursuant to subdivision (a) of Section 8769, it shall temporarily transfer available funds to the redemption fund upon determining that a deficiency exists. The moneys so transferred are to be used to pay sums due from the redemption fund and to be retransferred therefrom out of the first available receipts.
