California Code, Streets and Highways Code - SHC § 18076

If there is a majority protest by the landowners in any zone to the improvement in that zone, or if the officer or person designated reports that it is practical to subdivide a zone and a majority of the landowners in that subdivided zone protest the improvement in that subdivided zone, the city council shall strike that zone or subdivided zone from the proceedings and correct the proposed assessment accordingly, unless that body, by a four-fifths affirmative vote of all its members finds that the public interest and convenience require that street lights in that zone or subdivided zone be improved. The determination of the city council shall be final and conclusive.
