Cal. Sts. & Hy. Code § 19165.1
As an alternative to the petition procedure, the board of supervisors, by a four-fifths vote, may determine that the public safety and convenience require replacement of an obsolete system. The resolution may propose that a temporary zone be established, which zone will be benefited by the work, for the purpose of levying a special tax in the zone to finance the cost of the work.
The resolution shall contain that matter required by Section 19166. Notice and hearing of the resolution shall be substantially as required by Sections 19168 and 19169. If the board of supervisors determines at the hearing, by a four-fifths vote, that it is just and equitable and in the public interest that the obsolete lighting be replaced and that the proposed temporary zone be formed, it shall fix and describe the boundaries of the proposed zone in a manner so as to exclude any territory which will not be benefited by inclusion in the zone; it shall declare the zone established; it shall designate the zone by a name or number; and it shall specify the duration and purposes of the zone, not to exceed 10 years from the beginning of the next ensuing fiscal year in which a special tax levy may be made in the zone.
Except as provided in this section, any zone formed under this section is subject to Chapter 9.5 (commencing with Section 19165).
