The big T flood was more like a 1 in 10,000 yr event according to what I have read.
If I recall correctly, riverbed projects that the core of engineers look at typically look at the 100 yr floodplain.
The red lion bridge obviously couldn't stand up to flows that seem more like a 1 in 10-20 yr flow.
The owner should step up and put in a bridge that 1) doesn't impede boating traffic, 2) meets boulder regs, and 3) doesn't fall into the creek if we get some high flows.
Anyone from the boating community talking to the boulder folks about this issue?
