Vial v. City of San Diego (1981) 122 Cal. App. 3d 346 involved an ordinance of a charter city declaring payment of prevailing wages to be appropriate "'only when required by Federal or State grants and on other jobs considered to be of State concern ....'" The issue was whether the ordinance impermissibly conflicted with the state's prevailing wage law. Avoiding a decision on whether the payment of prevailing wages is, in the abstract, a "municipal affair" or a matter of "statewide concern," the court held the state prevailing wage law "does not apply to the public works projects of a chartered city, as long as the projects in question are within the realm of 'municipal affairs' ."
