Sustainability Goal

A Groundwater Sustainability Plan for the Basin was submitted to DWR in January 2020 and is now posted on the DWR website.  DWR recently extended its public comment period on the Basin GSP to June 3, 2020

The Sustainability Goal is set out in the Basin GSP:

Manage the groundwater Basin to ensure beneficial uses and users have access to a safe and reliable groundwater supply that meets current and future Basin demand without causing undesirable results to:

  • Ensure groundwater is available for beneficial uses and a diverse population of beneficial users;
  • Protect groundwater supply against seawater intrusion;
  • Prevent groundwater overdraft within the Basin and resolves problems resulting from prior overdraft;
  • Maintain or enhance groundwater levels where groundwater dependent ecosystems exist;
  • Maintain or enhance groundwater contributions to streamflow;
  • Ensure operational flexibility within the Basin by maintaining a drought reserve;
  • Support reliable groundwater supply and quality to promote public health and welfare;
  • Account for changing groundwater conditions related to projected climate change and sea level rise in Basin planning and management;
  • Do no harm to neighboring groundwater basins in regional efforts to achieve groundwater sustainability.
