“There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things.”
Niccolo Machiavelli
Salinas Valley Basin Groundwater Sustainability Agency
• Six Subbasins• 110 Miles Long• Joint Powers Authority• Eleven Member Board• Staffed by Contract
(Regional Government Services)• Three Part Time Staff • Admin on call
Seven Years a New Agency and-Six GSP’s
This is how we are doing it!

CSIP Issues
• Underfunded from the Beginning• Value Engineered• Lack of Maintenance• Supplemental Well Failures• CSIP Managed by Two Different Water Agencies
• Monterey 1 Water – Production and Distribution• Monterey County Water Resources Agency –OPS, Infrastructure and Admin
• Difficult to Measure Effectiveness• Perceived to be Unfairly Funded

Seawater Extraction Barrier
• Designed to halt and reverse seawater intrusion• Relatively high cost, but a definitive fix• State of extracted water TBD• Optional injection barrier addressed

Speaking of Systems
Question:
Shouldn’t those of us who struggle with Seawater Intrusion be working together for better solutions?
