The San Diego County Water Authority’s Board of Directors Thursday unanimously voted to support current plans for California WaterFix, the state’s $17 billion proposal to address water supply constraints in the Sacramento-San Joaquin Bay-Delta.

The board’s backing is contingent on a financing plan that fairly allocates project costs to San Diego County taxpayers, according to the Water Authority. The Metropolitan Water District of Southern California, the sole source of Bay-Delta water for the San Diego region, is responsible for such allocations.
