Thank you for visiting the Local Agency Formation Commission (LAFCO) of Napa County’s website; the governmental agency designated by the California Legislature to manage local governmental boundaries, evaluate municipal services, and protect prime agriculture lands.  LAFCO will be proactive in raising awareness and building partnerships to accomplish this through its special studies, programs and actions.

Everything you need to understand and work with LAFCO is available on this website.  This includes downloading application materials, viewing staff reports and studies, and identifying helpful resources relating to growth management in Napa County as well as for the entire San Francisco Bay Area region. You are also welcome to contact us with any comments or questions by visiting the about us page.

Who uses LAFCO?

  • Individual home owners requesting annexation to a sewer district due to a failing septic tank.
  • Developers seeking annexation to cities in order to obtain more favorable development and urban services extended to the new housing.
  • Cities wishing to annex pockets or "islands" of unincorporated land located within their borders in order to avoid duplication of services with the county.
  • Special Districts or cities seeking to consolidate two or more governmental agencies into one, thereby streamlining their services and reducing the cost to local taxpayers. 


CALAFCO (California Association of Local Agency Formation Commissions) is an organization dedicated to assisting member LAFCos with educational, technical and legislative resources that otherwise would not be available. To learn more about CALAFCO, please view the following video:

LAFCO has initiated a Municipal Service Review for all special districts and cities that provide water, wastewater, and/or recycled water in Napa County. The project has kicked off and is undergoing the data collection phase. It is anticipated that the project will be finalized in February 2020. Further details can be found on the project website by clicking here.

Given LAFCO’s interest in ensuring public involvement, over the course of the project, the public will be solicited for input through written comments on the draft report, as well as at a public workshop and a LAFCO public hearing. Additionally, the website has feedback forms for various facets of the project, as well as contact information to direct questions or comments.

LAFCO will hold a special public workshop on Monday, March 11, 2019 in Yountville from 9:00-12:00. The workshop will be separated into two distinct topics: (1) an educational “LAFCO 101” presentation by staff and (2) a robust discussion with interested stakeholders relating to the draft Policy on Spheres of Influence prepared by the Policy Committee. A flyer on the workshop and the agenda can be viewed by clicking this link:
