NOTICE OF PROPOSED RATE CHANGE BEFORE THE CALIFORNIA PUBLIC UTILITIES COMMISSION (CPUC) On or around May 4, 2026, Cal Water will file Advice Letter 2579 requesting authority to increase revenues to recover recently completed and previously authorized infrastructure improvements. In the advice letter, Cal Water requests additional revenue of $998,615, or 0.8% of currently authorized revenue. If approved, effective July 1, 2026, the water bill of a Bay Area Region residential customer with 6 CCF (which is 600 cubic feet, or approximately 4,488 gallons) of monthly water usage would increase by approximately $0.47, or 0.8%. Although previously authorized by the CPUC in Decisions 26-04-045, 24-03-042 and 20-12-007 as part of the utility's triennial rate review process, the project's cost could only be recovered through a rate increase after it was completed. A copy of Advice Letter 2579 will be available on the internet at https://www.calwater.com/rates-advice-letters/ (for Bayshore - please select the Bayshore (Bay Area Region) district from the drop-down menu or for Redwood Valley please select the Redwood Valley (Bay Area Region) district from the drop-down menu), and may also be obtained from the company's Bayshore district local office by calling (650) 558-7800 or Redwood Valley district local office by calling (707) 274-6624. You may also contact the company's headquarters by mailing the Rates Department at 1720 North First Street, San Jose, California 95112-4598, or by calling (408) 367-8200 and asking for the Rates Department. Cal Water offers many programs to help you manage your water bill including a Customer Assistance Program (CAP), (formerly, low-income ratepayer assistance program (LIRA)), water conserving appliance rebates, and other conservation programs. Please visit our website at www.calwater.com to take advantage of these opportunities. Protests and Responses. Anyone may respond to or protest this filing. A response supports the filing and may contain information that proves useful to the Commission in its evaluation. A protest objects to the filing in whole or in part and must set forth the specific grounds on which it is based, and shall provide citations or proof where available to allow Commission staff to properly consider the protest. The grounds for protests are: 1. The utility did not properly serve or give notice of the filing. 2. The relief requested in the filing would violate statute or Commission order, or is not authorized by statute or Commission order on which the utility relies. 3. The analysis, calculations, or data in the filing contains material error or omissions. 4. The relief requested in the filing is pending before the Commission in a formal proceeding, or 5. The relief requested in the filing requires consideration in a formal hearing, or is otherwise inappropriate for the filing process, or 6. The relief requested in the filing is unjust, unreasonable, or discriminatory (provided that such a protest may not be made where it would require relitigating a prior order of the Commission). A response or protest must be made in writing and received by the Commission's Water Division by May 24, 2026, the end of the comment period. The response or protest should be sent to the CPUC (by email to water.division@cpuc.ca.gov, or by mail to the Tariff Unit, Water Division, 3rd Floor, CPUC, 505 Van Ness Avenue, San Francisco, CA 94102) and to Cal Water (by email to cwsrates@calwater.com, or by mail to the Rates Department, California Water Service Company, 1720 N. 1st Street, San Jose, CA 95112).
