1000 year event? Don't think I've ever seen that indicated before, but that's a much better situation than a 100 year event. Haven't we had some 500 year events in the past 10 years?
Still have to design for it. I don't think this area has seen anything close to a 500 in quite some time. A couple of years ago, when a lot of the areas were flooding the measurement location just upstream peaked at 7 tenths below the 100' elevation.
*edit* I don't even think it was over a 500 year event when Montgomery Wards was under water.
All of the occupied spaces are 2' above the project flood elevation established by the Corps of engineers. That's about 12' above the 100 year elevation.
Maybe I am thinking of Midland. I'm pretty sure someone has had a 500 in the last 10 years.
They must be getting a map revision, because you normally can't build in the floodway and I'd say a majority of their site is solidly in the floodway, much less the 100 year floodplain. This is a curious project for me.
Of course, these conditions are pre-bypass channel and downstream Gateway park storage, etc. I wonder how much of their engineering relies on the Panther Island Project being completed.
