Draft GSP Sections

The GSP development process is an iterative one. Groundwater sustainability issues and draft GSP sections are presented to the GSPAC and the public, discussed, and refined over time. Online surveys are used to gather ideas and feedback on key issues. Survey feedback helps to build a stronger draft GSP. A compiled draft GSP will be released in Fall 2021 for additional public comment and input.
