San Andreas business closure triggers permanent layoffs at Pool Station Road facility

A California Employment Development Department WARN report records the permanent closure of a Sentinel Transportation LLC facility at 746 Pool Station Road in San Andreas, along with permanent layoffs affecting three workers at the location.

The state filing lists May 31, 2026, as the effective closure date. For San Andreas workers and nearby businesses, the documented immediate effect is the loss of three positions at the Pool Station Road facility. The record identifies the local site and affected workers, but does not indicate that the action applies to all of Sentinel Transportation’s operations in California.

What the WARN filing says

The entry appears in the California EDD WARN report covering July 1, 2025, through June 30, 2026. It lists Sentinel Transportation LLC under Calaveras County and identifies the facility as 746 Pool Station Road, San Andreas, CA 95249.

The entry classifies the event in two ways: as a permanent closure and as permanent layoffs. It lists three affected workers at the San Andreas location. Those designations describe the action recorded for that facility; they do not establish that every person connected with Sentinel Transportation lost employment.

The filing records March 25, 2026, as the WARN notice date. The California EDD record shows that it received the notice on March 30, 2026, ahead of the May 31 effective closure date.

What is not established

The WARN record does not explain why the facility is closing. It also does not say whether the property has been sold, repurposed or otherwise transferred. The approved local reporting packet does not identify a separate detailed Sentinel closure story, current company statement or local government redevelopment record for the property.

That leaves the state filing as the controlling documented source for the closure and layoffs. It confirms the address, county, number of affected workers and key dates, but it does not describe the facility’s day-to-day operations or establish a broader change to transportation services in San Andreas.

Next date

The next known date in the record is May 31, 2026, the listed effective closure date. No additional property, redevelopment or operational deadline is provided in the approved source packet.
