In October 2017, the Water Forum and local groundwater agencies held a series of three public workshops across the Cosumnes Subbasin. The workshops offered an opportunity for local residents to learn more about the Cosumnes Subbasin’s efforts to meet the requirements of the Sustainable Groundwater Management Act (SGMA) and to share input on how their area can best implement SGMA locally.

Communication & Engagement Plan – The purpose of the Cosumnes Communication and Engagement Plan (C&E Plan) is to share information, foster active engagement, solicit informed feedback, and develop widespread support for SGMA implementation in the Cosumnes Subbasin. The Cosumnes C&E Plan was originally developed in 2017 and updated periodically to guide GSP development. The C&E Plan is intended to be a living document to support communication, outreach, and engagement during GSP implementation. View the most recent version here – (Summer 2021 Draft Update)

Stakeholder Survey (January 2019) – GSAs sent a direct mailing containing Subbasin Fact Sheet and Stakeholder Survey (or a link to these documents) to all landowners in the subbasin and received more than 210 survey responses. View survey findings presentation.
