Doesn't sound right,  It's not Florida.  Unless there was some backfill in the area, it should be a solid substrate. Area was once covered by glaciers. 
More likely, the fire line leaked at some time and created a void.

In the 70s or 80s a new plant in the Midwest was sinking. Can't remember which one but they read the ground density wrong, upside down, I think. Davis Besse is on the lake shore subject to flooding. I was stuck on site once due to flooding that surrounded the plant. Lake Erie is fairly shallow, and winds drive the lake up on the southern shore from time to time, so the ground may not be that compacted.

The sinking plant was Midland in Michigan. The nuclear plant got abandoned because of it. It was a 2 unit B&W plant just like the TMI plants. One unit was to supply heat to Dow Chemical. Toledo Edison owned lake shore property about 5 mi west of Port Clinton where they initially planned to build Davis Besse. Preliminary environmental studies in late '60s showed bedrock was closer to the surface at the current location, which was OH Wildlife land, so Toledo Edison traded their property with the state with agreement that the DB property outside the site boundary would remain a wildlife refuge. The construction was cheaper at the current location because of bedrock nearer to the surface.
