Building a Sustainable Groundwater Future in the SLO Basin


Groundwater is a vital contributor to our region’s water supply. Local agencies (the City and County of San Luis Obispo) are developing a Groundwater Sustainability Plan (GSP) to better manage this important water resource for the San Luis Obispo Valley Groundwater Basin (SLO Basin) while meeting the requirements of the Sustainable Groundwater Management Act (SGMA).


Planning has just started and there are several ways stakeholders can get involved in the plan development process. Learn more

Next Virtual Stakeholder Workshop: Groundwater Management Vision 


June 10, 2020 • 3:30pm-5:00pm • Zoom Meetings


In this virtual workshop, attendees will participate in an interactive exercise to set the vision for what a “sustainable SLO Basin” means. To inform the exercise, the project team will ground attendees in the key takeaways of the Basin Setting work completed to date, which helps predict future groundwater demand and describes the unique makeup and challenges associated with groundwater management in the SLO Basin. They’ll also describe the role of the Water Budget and the Surface/Groundwater Model in meeting the requirements of SGMA. A recording of the workshop will be published the project website within one day of the live session. Offered virtually through Zoom Meetings, registration required.
