Yes. But, say, if one solution is an order of magnitude cheaper than the other and can be implemented quickly, it may be economically feasible.
Seems the only one that needs real protection is Hilton, and I suppose the rest of the Iowa State Center.
Sorry for the lots, the soccer complex.
It appears that Lied and RCA are on the very fringes of the flooding, and neither today nor in '93 it reached Beach. So one would think small levies at that level should suffice for that area
Otherwise your plan might be feasible for Hilton, but what about the rest of the complex?
Does water get into Hilton from any place other than the east loading ramp? Are there many other internal doors at ground level? Never been in the bowels.
