Cal. Wat. Code § 72020.5
In addition to the provisions of Section 72020, in the Casitas Municipal Water District, the board may by resolution call a special election in the proposed improvement district for the purpose of submitting the question of the formation of the improvement district to the voters of the proposed improvement district. This special provision for Casitas Municipal Water District is necessary because the Legislature recognizes that certain proposed improvement districts in the Casitas Municipal Water District are controversial, that an election should be called, and that to require a petition to be circulated for recognized controversial improvement districts would constitute an unnecessary hardship. This problem is not common to all districts formed under this division. It is therefore hereby declared that a general law cannot be made applicable and that the enactment of this section as a special law is necessary for the solution of problems existing in the Casitas Municipal Water District.
