From what I recall, a 1:20 year flood prevention is entirely inadequate for a civil engineering job.marksi wrote:The area partially flooded last year before it had been completely excavated. The designers were asked if they were concerned about the potential for flooding but said they weren't, as that particular rainfall event only happened once every 20 years or so, and the pumps would be able to deal with it when it was finished.
I suspect there are some very worried civil engineers studying drawings today.
Even a layman knows that the weather has more extremes now than ever. I'm surprised it was rubber-stamped in the first place.
