Hannah,

Attached are a few pictures of the culverts at Commerce Drive from the ride through on 4/5/23.
They have tied the inlets and outlets in to the existing streams. Both culverts have been back-filled
with native material and now carry the live stream. The water in culvert 1 is too high to see the
sinuosity within the culvert, but you can see the sinuosity following the high and low sills and the
triangles of fill in culvert 2. Tom said he was good with how the culverts looked when we were on
site. Please take a look and let us know if you have any questions or comments about how things
turned out.

Tom, feel free to add any other comments you have too.

Thanks,
