New Water Requirements

On October 27, 2015 the Board of Supervisors adopted the Countywide Water Conservation Program to address ongoing water scarcity concerns. The amendments were effective on November 26, 2015 and affect the following areas:

  • Paso Robles Groundwater Basin:
    • New buildings and new irrigated agriculture must offset new water use. (Building and Construction Ordinance and The County Land Use Ordinance)
    • New construction and new irrigated agriculture in the Paso Robles Groundwater Basin must be water neutral. Please visit for forms, applications, and information.
  • Nipomo Mesa Water Conservation Area:
    • New buildings must offset new water use. (Building and Construction Ordinance)
  • Countywide:
    • Water waste prevention measures apply to all unincorporated areas where a similar program is not already operated by a water purveyor. (Health and Sanitation Ordinance)
    • Agricultural best management practices are encouraged in all unincorporated areas (The County Land Use Ordinance)
