Amy,
If James is in concurrence, we are ok with proceeding as you describe and it would be preferred to submit all repairs as

James and Dave,
As you know, its been a very wet fall and winter. We have had multiple large events (100+ year storms) in the area. We
have a few locations where streams are undermining or will undermine our fill slopes and need to be addressed for long
term stability. One area is downstream of the culvert on Smith Creek. There are a few locations along Smith Creek that
we are going to investigate further to determine the appropriate method. The fill in this area hasn't been installed yet,
so we have a little more time to come up with a plan. The other area is permit site 8. Martin Mill Creek has migrated
significantly since the project started and is now undermining the fill slope for the bridge. I have included a plan sheet
that shows the original location of the stream and the new locations, and a couple pictures. In the first picture you can
see the amount of sand that has been deposited forcing the stream to migrate away from it and toward our slope. I
outlined the new channel location. In the second picture, you can see rip rap in the distance (circled in red). This is
where the stream has migrated to and is undermining the fill slope. The plan here would be to install a channel with the
banks lined with rip rap through the sand and connect with the stream on the other side, and fill the old channel.
I would like to know if you are ok with us proceeding with this repair and submitting a permit modification package for
all sites at the same time. Let me know your thoughts.
