Why are people going into a single structure is beyond me . Is it the highest elevation around?

Possibly because it is made of reinforced concrete and is more or less flood proof.

Or maybe they had no other choice. I thought I heard one of the news guys say the field will be under water if the dikes get breached. They seem to be putting all the folks in the seats.
