Sinkhole Swallows Part of California Trader Joe’s Store

Trader Joe's enthusiasts know the routine: when it's time to stock up, you head straight to the store for all your must-haves. But what if you showed up and found the doors unexpectedly locked with little explanation. Well, that's what happened in Greenbrae, California, in July, when customers arrived at the Larkspur Trader Joe's, only to find the doors locked with a vague sign stating the store was closed for "unexpected construction." However, San Francisco's KRON later revealed the real cause of the closure was a sinkhole that had formed in the back of the store. Check this out.

According to the U.S. Geological Survey, a sinkhole is defined as "a depression in the ground that has no natural external surface drainage." In layman's terms, that means when it rains, water is retained within the sinkhole space underground. The water eventually eats away at and dissolves the soluble rock beneath it, causing the phenomenon to occur. Types of soluble rocks that can dissolve in groundwater include carbonate rock such as limestone and dolomite rock. When the space left behind by dissolved rock gets so big that it can no longer support the weight of the land or buildings above, it collapses, consuming the collapsed content into a massive void.

While there is no data recorded for the number of annual sinkholes that collapse each year in the U.S., there is record of the largest sinkhole ever recorded. Known as the "Golly Hole" in Shelby County, Alabama, the sudden collapse took place in 1972, and was a massive 325 feet long, 300 feet wide, and 120 feet deep. The image above shows a massive sinkhole that opened up in Winter Park, Florida back in 1981.

While there are no national statistics kept on annual sinkholes, the Florida Office of Insurance Regulation states that from 2006-2010, sinkhole claims in the state totaled $1.4 billion. In terms of annual deaths, a University of Florida professor who is also a contractor and has spent his career studying sinkholes, says that only two people have died in the past 40 years from sinkholes. In 2013, Jeff Bush was sleeping when the earth opened up and consumed his home. His body was never found, and though the home has long since been gone, the sinkhole has opened up two more times.

A post on Reddit from more than a week ago states the following: "TJs employee here. Gonna keep it short and sweet, the dairy fridge is literally sinking into the crawlspace below and there are visible cracks in the floor and a noticeable slope. An engineer/inspector is coming over soon to survey how bad it is, but there's no official word on if it's unsafe or not. Additionally, we were told to limit our answers to questions about it to just being a "construction project" (since the fridge is closed off), which seems pretty sketchy."

While the unexpected construction was originally thought to be due to a bad subfloor that started to sag due to the weight of the refrigerators, KRON reported that the Marin County Trader Joe's was closed because a sinkhole opened within the store. Trader Joe's remained incredibly silent about the matter.

The most recent update on Reddit states that the Larkspur store will be closed indefinitely. As the construction crew is working to remedy the situation, they're finding more issues. Additionally, the sinkhole is impacting a liquor store in the same plaza, which indicates the sinkhole is incredibly large. The TJs website states that this location is closed for maintenance. Fans of the store will have to head to the nearby Trader Joe's in San Rafael for their Everything But the Bagel seasoning and cheap wine fix!
