Amid California’s worsening drought, Pleasanton city officials on Tuesday are expected to declare a local drought and water shortage emergency, and require residents to reduce their water usage by 15%. The Pleasanton City Council will vote at Tuesday’s meeting. In a report accompanying the council’s agenda, staff urged council members to make such declarations after board members with the Zone 7 Water Agency voted to do the same in September. The water agency, which serves the cities of Livermore, Pleasanton, Dublin, San Ramon and parts of Dougherty, said Tri-Valley customers are falling short on water reduction compared with 2020.
