City 17 = Half-Life 2 reference?

Not really sure if there was a City 17 in the Soviet Union, but I was reading the plot to the Half-Life 2 series today and found some striking similarities between the two, at least the name and location.

"In the Eastern European settlement City 17, Freeman meets surviving members of the Black Mesa incident, including Isaac Kleiner, Barney Calhoun, Eli Vance and his daughter Alyx Vance, and aids in the human resistance against Combine rule"

"City 17 is a dystopian metropolitan area in Eastern Europe that forms the primary setting for Half-Life 2 and its first expansion, Episode One. The city features a variety of architectural styles, mostly Eastern European architecture dating from pre-World War II neoclassicism, to post-war revival of classical designs, Soviet Union modernism, and post-Soviet contemporary designs, as well as Combine structures. The playable area of the city is quite large, including a railway station, a dilapidated canal system, underground road tunnels, and multiple communal living quarters and crowded, tightly-packed tenement buildings."

The architecture of a Pre-World War II and Soviet Union Modernism is similar to the Industrialized Hamlet as depicted in the maps description, as well as the fact that both cities have railway stations.

quite possibly. the soviets really did name cities like that though.
