Jennifer,
As discussed, attached is the detail showing the gabion mattress inside the drainage junctions to address the aquatic life
movement general condition. Please review and comment. If you are o.k. with this concept, I will proceed to revise the
impact maps to include this detail, and also include some construction notes for pumping around if a rain event should
occur. Just a reminder that we are not installing a rip rap apron at the outlet because we are addressing the velocity by
using flat slopes on the pipes and having the 12" drops inside the junctions.
Thanks,
