Cal. Government Code § 13995.63

(a) Upon receipt of the resolution required by Section 13995.60, including any assessed business referendum request pursuant to subdivision (a) of Section 13995.52 or Section 13995.62, the director shall establish a referendum period not to exceed 60 days. If the director determines that the referendum period so established does not provide sufficient time for the balloting, the director may extend the referendum period not more than 15 additional days. At the close of the referendum period, the director shall count and tabulate the ballots filed during the referendum period. (b) The director shall establish a deadline for adoption of the resolution described in subdivision (a). If the commission fails to meet this deadline, or if the adopted resolution fails to meet the requirements of this chapter, then assessed businesses may present a slate of candidates to the director not later than 60 days following the deadline established for the commission resolution. A minimum of 10 percent of weighted voters shall sign the document presenting the slate. (c) In the event that the director does not receive a resolution required by Section 13995.60 from the commission by the deadline established pursuant to subdivision (b) or the resolution does not comply with the requirements of this chapter and the assessed businesses fail to present a slate pursuant to subdivision (b), then the director shall select a slate of commissioners and this slate, added to any assessed business referendum requests pursuant to subdivision (a) of Section 13995.52 or Section 13995.62, shall constitute the items included in the referendum.
