Sonoma LAFCO Local Agency Formation Commission

Date: November, 2012

New State Requirements for Mutual Water Companies

California State Assembly Bill 54 was approved and signed into law in 2011, becoming effective this year. The legislation focuses on mutual water companies and involves, in part, provision of information and materials to Local Agency Formation Commissions (LAFCO). LAFCOs exist in each county in California as independent public agencies. Among other responsibilities, LAFCOs regulate the boundaries of cities and special districts.

The legislation, which is attached for your information, requires mutual water companies to:

  • Submit to LAFCOs a map depicting the boundaries of the area the company serves and
  • Upon request, provide information which may be used in LAFCO-initiated studies called Municipal Service Reviews.

The law allows LAFCOs to determine whether companies comply with the Safe Drinking Water Act and also authorizes LAFCOs to approve or disapprove annexation to a city or special district of territory served by a mutual water company, should that be proposed.

To fulfill mandates of state law, Sonoma LAFCO requests the cooperation and assistance of your mutual water company to:

  • Complete a short survey of information relating to your mutual water company.
    Please complete the survey (Word: 113 kB ) . Instructions for submittal of the completed inventory to Sonoma LAFCO can be found at the end. If you would like a paper copy of the survey to complete, please contact LAFCO staff at (707) 565-2577.
  • Provide a map depicting the boundaries of the territory your mutual water company serves.
    LAFCO staff has worked with Sonoma County Information Systems Department (ISD) to develop an instrument whereby you can identify parcels served by your mutual water company and create an on-line map. You can use addresses or Assessor’s Parcel Numbers or "zoom" features for an area. Information on the URL address and access to the mapping instrument has been mailed to each water company.

    We would encourage you to use the mapping instrument.

    If you experience problems with the website you can contact the ISD Service Desk, by either calling (707) 565-2030 or by emailing Please provide the subject of the call/email as “Sonoma LAFCO: Mutual Water Company Mapping – Issues with Website” so that you can be directed to the appropriate staff person to help you. Indicate the problem you are having and leave your name and contact information (either telephone number or email address where you can be reached).

    Please note: Although the current instrument does not allow you to print a hard copy map, LAFCO staff will be able to send one to you upon request.

    Should you prefer, you can provide your own hard copy map, no less than 8½” X 11” in size, as long as it shows the parcels served by your mutual water company by either address or Assessor’s Parcel Number.
  • Provide a copy of your company’s Articles of Incorporation and Bylaws.
  • Provide a copy of your company’s most recent consumer confidence and water quality reports.

Please complete the survey (Word: 113 kB ) and provide the map and other requested information and materials by Friday, December 14, 2012.
