GSP Development

The County received state grant funding to develop a GSP in compliance with the Sustainable Groundwater Management Act (SGMA). Thus, the County of San Luis Obispo GSA and the City of Arroyo Grande GSA are jointly developing a Groundwater Sustainability Plan (GSP) for the sustainable management of the Arroyo Grande Subbasin. The technical analysis resulting from the development of the GSP will provide information necessary for the preparation of the Arroyo Grande Creek Habitat Conservation Plan under development by the San Luis Obispo County Flood Control and Water Conservation District. A key component in the GSP includes the development of an integrated surface water and groundwater model that will help decision makers better understand the interconnections between the groundwater basin and the Arroyo Grande Creek watershed.

Workshop #1: Basin Setting and Visioning

Tuesday, December 15, 2020 • 3:00pm-5:00pm • Virtual via Zoom Webinar

In this virtual workshop, attendees helped create a shared set of guiding principles for what a “sustainable Arroyo Grande Subbasin” means. To inform the interactive exercise, the project team described the purpose of the Groundwater Sustainability Plan (GSP), including how it will support and integrate with other initiatives like the Watershed Management Plan and Habitat Conservation Plan. The team also described some basics of groundwater and the requirements of the Sustainable Groundwater Management Act (SGMA) in easy-to-understand terms. Next, they provided an overview of the Basin Setting including the Basin’s unique geological makeup, potential challenges associated with groundwater management, and anticipated future groundwater use. Stakeholders input documented in the workshop activity will be used to create a set of guiding principles that will inform the remaining GSP decisions.

Workshop #3: Projects and Management Actions

Date/time to be determined • Virtual via Zoom Webinar

In this virtual workshop, stakeholders will help inform a preliminary set of projects and management actions that will be used over the next 20 years to reach the sustainability goals set for the basin. To inform the interactive exercises, the project team will recap the guiding principles developed with stakeholders, as well as the sustainability goals developed in workshop #2. Activities will surface considerations for sharing project costs, and an implementation plan that keeps the approach flexible and on track. Stakeholder input documented in this workshop will be used to draft chapters 9-10 of the GSP. Registration Opens Soon
