From what I understand, money is the issue, and this project will require alot of it. The city has the RICD for what that is worth, and the 404 permit should not be difficult to get. Unfortunately, the park can't be built on a shoestring by unemployed kayakers for two reasons. First, to get the perfected water right under the RICD, the in-channel structures have to be constucted by a licensed engineer. Second, at peak flows, the Animas will take out anything that is not anchored really solidly. Remember how much the riverbed changed in 2008?
On the bright side, at least we have a park that still works at high flows.
Corner pocket comes in at 1500
Smelter wave at 1800-2000
Santa Rita comes in at 2500
The Sawmill waves come in at 4000
A rebuilt park with some low water features would really extend the season though...
