Stakeholder Input

One of the requirements of the Sustainable Groundwater Management Act is for active and effective public input on the Solano Subbasin Groundwater Sustainability Plan. There are multiple ways for you stay on top of the plan as it comes together and to provide input:

  • Staying informed: sign up for the Subbasin Groundwater Sustainability Plan email list. You will get periodic updates on the Plan as well as useful information about groundwater in the region.
  • Engaging: participate in one or all of the public input workshops that will be held once or twice a year throughout the four-year plan development process. These workshops will be timed at key moments when your input and insight will be critical.
  • Connecting: Each GSA is the Collaborative is governed by a board and supported by staff. You are always encouraged to check in with your local representatives in the Plan development process.

Our goal is to have a robust, transparent process that brings people together around key questions that will influence the development of the Groundwater Sustainability Plan.

Community input is being facilitated by Ag Innovations, a nonprofit devoted to facilitating collaboration around issues related to agriculture, water, and our future. Ag Innovations facilitated past SGMA related workshops in the Solano Subbasin. You may also hear from The Freshwater Trust or the Local Government Commission, who received a grant to expand on community input in the Solano Subbasin.
