Senate Bill 552: Drought Planning for Small Water Supplies & Rural Communities

Senate Bill 552 (SB 552) was passed by the California Legislature in September 2021, placing more responsibilities on both local and State governments for preparing and acting in the event of a water shortage in rural communities. The bill calls for proactive drought preparedness for the most vulnerable communities by improving their management during future droughts, ultimately preventing catastrophic impacts on drinking water supplies.
 

County Compliance

As per SB 552, each county was presented with two main requirements to facilitate drought planning for water systems with fewer than 14 connections, including individual wells: the first was to establish and hold a standing drought task force, and the other was to develop a drought and water shortage resilience plan. Counties were able to establish alternative processes to meet these requirements.

The standing county drought task force was created similar to the DRIP Collaborative for the state, which provides opportunities for coordinating and communicating with the state and other local governments, community-based organizations, local water suppliers, and local residents on a regular basis. The County of San Luis Obispo met this requirement by including a standing agenda item to report on drought planning during public meetings of the Water Resources Advisory Committee.

Drought and water shortage resilience plans serve three purposes: 

  • present potential drought and water shortage risk for rural communities
  • propose interim and long-term drinking water solutions to said risk, and
  • identify available funding sources and necessary plan implementation steps

The County has completed the drought and water shortage resilience plan requirement by a combination of Drought sections of the Multi-Jurisdictional Hazard Mitigation Plan (MJHMP) and relevant County websites. The 2025 MJHMP Update was utilized to elaborate on necessary drought information within the MJHMP while the following County websites; County Environmental Health, SLO County Water, Public Works Projects, and County OES, provide additional information.

Furthermore, County SB552 efforts aligned with two other current major regional water planning efforts - the 2026 Master Water Report & Data and Information Management System and the DESAL Plan. Altogether, these efforts strive to maintain existing water sources, create new water sources, and allow for easy data transparency to the public.

FAQs

SB552 was signed into law in 2021 creating drought preparedness planning requirements specific to the state’s rural communities and their water systems (state small water systems and domestic wells). These requirements are shared between the State and local governments, placing the responsibility of not only preparing for but also acting in times of water shortage on both governments.
The County has given multiple presentations during the project timeline to serve as updates on County SB552 efforts and compliance. Please see the table below for those presentations, the group/venue they were given at, and the dates.

Rural communities dependent on one water source via either domestic well or state small water system began experiencing water shortages after the 2012-2016 drought. SB552 provides much needed focus specifically for rural communities to assist them with their drought planning.

Overall, the main goals of the bill are to:
  • Reduce the risk of water shortage for small water suppliers, state small water systems, and individual (domestic) wells
  • Improve access to financial and technical resources
  • Promote proactive planning, coordination, and collaboration
  • Delegate responsibilities to counties and local agencies
It depends on the number of connections the well has. Domestic Wells are single source water systems consisting of only 1-4 connections. State Small Water Systems are single-source water systems consisting of 5-14 connections.
No, neither the County nor State have the authority to force consolidation on any wells not serviced by either, regardless of location. SB552 plans only provide recommendations and suggestions for consolidation depending on factors like location and identified water shortage risk.
So far, five counties have completed both requirements. The five counties are listed below along with their drought resilience plan or alternative process. All other counties have at least established their drought task forces but all are working towards completing their drought resilience plan or equivalent alternative process.

Alternative processes have been completed for both requirements.

The standing drought task force is led by the Public Works Department and consists of an internal working group of staff from multiple County departments and agencies. Also, the Water Resources Advisory Committee (WRAC) is being utilized as the public committee serving the task force.

The drought resilience plan has been integrated into the San Luis Obispo County Multi-Jurisdictional Hazard Mitigation Plan (MJHMP) through the 2025 update as well as existing County websites and additional produced documents. Additional documents were created by County Public Works Department and State consultant staff through direct technical assistance to fulfill remaining compliance requirements not covered by the two former methods.
The State has established and maintained multiple resources for counties and small water suppliers to use for SB552 efforts. These resources include the Drought Resilience Interagency and Partners (DRIP) Collaborative, DWR Water Shortage Vulnerability Tool and Data, and the DWR County Drought Resilience Planning Assistance Program. Each resource provides a unique service:
  1. The DRIP Collaborative is the state equivalent to a county drought task force.
  2. The DWR Water Shortage Vulnerability Tool provides the latest data regarding drought and water shortage vulnerabilities and associated risks for counties and small water suppliers to use for SB552 efforts. DWR regularly updates the data.
  3. The DWR County Drought Resilience Planning Assistance Program is a hub for counties to seek essential resources for assistance with SB552 efforts. These resources range from guidance and technical assistance to financial assistance.
Water systems covering urban areas oversee their own drought resilience plans separate from the County. Please look to your water system specifically for their efforts.
