What's behind competing Tennova, Ascension Saint Thomas hospital proposals?

Was it strategy, opportunity or just coincidence that Tennova and Ascension Saint Thomas were trying to open hospitals next to one another?

Also, what should be done to improve safety at Billy Dunlop Park, can someone give answers to flooded Clarksville residents, and who's going to pay to save historic buildings?
