Authorities Decision

Well, crap.  At some point, you just have to hang it all on the line and decide. So you open your handy-dandy pamphlet 
and look at the options.  And at some point, you have to PICK ONE.

Ecosystem projects: 

Description of 206 - Aquatic Ecosystem Restoration, Water Resources Development Act of 1996 (PL 104303), as amended.   Is there anything here that feels like an Ecosystem restoration?  

Description of 1135 - Project Modifications for Improvement of the Environment, Water Resource Development Act of 1986 (PL 99-662), as amended.   So there is a Federal project adjacent, and this almost seems like the right decision.  But it is not the eco link that we are looking for.  But maybe... #link

Section 204 - Beneficial Uses of Dredged Material, Water Resources Development Act of 1992 (PL 102580), as amended. Nothing here like that.  But if you want to, you can click on this link. It is always nice to learn about other authorities.

But wait.  Isn't this a Flood risk Management project? 

Section 205 - Flood Control Act of 1948 (PL 80-858), as amended, for flood control. This project is flood control related - when the river got out of the bankline in 2010, there was a large amount of damage to nearby homes - $300M and more.  There have been floods for a number of the previous 20 years, and the flooding period seems to be accelerating.  #link

Or maybe a CAP 14

Section 14: Flood Control Act of 1946 (PL 79-526), as amended for emergency streambank & shoreline erosion protection for public facilities & services. 

This one is probably the right choice.  There are public facilities (railroad) and the erosion of the streambank makes it the likely choice.
