Early April 1999.

Just returned from Kansas City, which has its interests, but I was too occupied to see much of it, except for a “tour” given by an office developer. He knew the market well, and as you’d imagine, liked to talk.

We visited SubTropolis at one point, which is an underground warehouse and distribution complex, created from a former limestone mine, which was dug straight into the side of a KC hill. The former mine space now houses all kinds of goods, plus some thousands of people who work there. One of their big tenants is the post office, which stores millions of stamps there.

Postscript 2013: I toured a fair amount of commercial real estate in 1999, so this description sounds blase, but actually I was taken with SubTropolis, as I often am with places I’ve never seen before.

More recently, Steve Nadis wrote in The Atlantic: “With 5 million square feet of leased warehouse, light-industry, and office space, and a network of more than two miles of rail lines and six miles of roads, SubTropolis is the world’s largest underground business complex… [and not the only one in KC]. More than 10 percent of the industrial space in greater Kansas City is located ‘down under,’ covering about 25 million square feet—an area bigger than the downtown business district. Mining limestone for use in roadway construction and agriculture continues, with additional acreage carved out each year.”
