In this virtual workshop, stakeholders will participate in a collaborative brainstorm to arrive at a preliminary set of projects and management actions that will be used over the next 20 years to equitably and cost-effectively maintain sustainable groundwater levels in the Big Bear Valley Basin. To inform the interactive exercises, the project team will recap (A) guiding principles stakeholders helped develop from Workshop #1, (B) the Basin Sustainability Goals, representative wells, sustainable management criteria, minimum thresholds and measurable objectives drafted following workshop #2, and (C) the criteria for projects and management actions that were captured in Workshop #2. Activities will surface considerations for distributing project costs equitably, and an implementation plan that keeps the approach flexible and on track. Stakeholder input documented in this workshop will inform relevant draft chapters of the GSP. A workshop recording and a public-facing summary of stakeholder input will be published to the GSA website following the workshop.
