Cal. Health & Saf. Code § 51367
The agency shall not at any time issue bonds if, upon issuance of the bonds, the amount in any bond reserve fund, established pursuant to Section 51366 to secure such bonds or any previous issuance of bonds so secured by such bond reserve fund, will be less than the minimum bond reserve fund requirement for such fund, unless the agency at the time of issuance of such bonds, shall deposit in such fund from the proceeds of the bonds to be issued, or from other sources, an amount which, together with the amount then in such fund, will not be less than the minimum bond reserve fund requirement for such fund. For the purposes of this chapter, the term "minimum bond reserve fund requirement" shall mean, as of any particular date of computation, the amount, as provided in the resolution or resolutions of the agency authorizing the bonds with respect to which such bond reserve fund is created, that is established as a reserve for current or future obligations to the bondholders.
