Ambler Park’s 2026 Groundwater Study: Local Wells Supply Everything, With No Imported-Water Backup

AMBLER PARK, Monterey County — October 30, 2026. Ambler Park’s neighborhood water supply is highlighted in a March 2026 Salinas Valley Basin Groundwater Sustainability Agency feasibility study. The study puts the California American Water Ambler Park satellite system’s 10-year average water demand at approximately 189 acre-feet per year. Its central finding for households is simple: the Ambler Park and nearby Toro systems rely entirely on local groundwater wells rather than imported water or recycled-water deliveries.

What does the long-term demand figure mean?

An acre-foot is approximately 326,000 U.S. gallons, so 189 acre-feet is roughly 61.6 million gallons over a year. The report uses a long-term historical average, and says water use in both small systems tends to peak in July and reach its lowest levels in January or February. That is a planning calculation, not a meter reading for October 2026 or a statement that each household uses an equal share.

Why was Ambler Park included?

The regional agency is studying ways to protect the Salinas Valley’s aquifers from seawater intrusion and manage long-term pumping demand. Its March 2026 Brackish Groundwater Restoration Project feasibility study considered water-treatment and aquifer-recharge alternatives. Including Ambler Park as a baseline supplier does not establish that the community has contaminated wells, that a desalination pipe is approved for its homes or that customers will receive a new water supply.

What happens after the study?

The agency says completing the feasibility study makes the project eligible for consideration for future federal participation of up to 25% of qualifying costs. It subsequently began evaluating combinations of regional alternatives through its Integrated Implementation Strategy. A feasibility study is not a construction contract, guarantee of federal funding or timetable for Ambler Park service changes.

How do customers compare different population estimates?

The state drinking-water system inventory lists a larger population-served estimate than the 980 residents quoted for Ambler Park in the 2026 feasibility report. These numbers originate from different reporting methods and snapshots and should not be treated as evidence that people moved in or out during a specific month. For the official utility’s current service connections, refer to state system CA2710006; for regional demand planning, consult the agency’s feasibility report.
