Frequently Asked Questions (FAQs)
The purpose these FAQs are to provide stakeholders and the community with easy access to clear, concise answers to common questions and concerns regarding groundwater sustainability planning and sustainable groundwater management in the Napa Valley Subbasin. FAQs are compiled from questions received by GSA staff, the Groundwater Sustainability Plan Advisory Committee (GSPAC), as well as FAQs prepared by other GSAs in California. The GSA staff and the consultant team are using their resources, expertise and professional judgment to prepare and organize the FAQs.
The FAQs are dynamic. Questions may be combined, added and modified to create an approachable and informative knowledge base. Answers will be updated or improved upon over time as additional groundwater-related data are collected and as the Groundwater Sustainability Plan process progresses. Responses will refer, as appropriate, to published, authoritative sources and are meant to be well informed but should not be construed to be the unchanging, definitive answer to every single question.
