Sheet 9:
No impacts.
Sheet 10:
No comments.
Sheet 11:
Station 537+00 -L- Left (Structure 1103): Investigate realigning 30" CSP with JS.
Sheet 12:
No impacts.
Sheet 13:
No comments.
Sheet 14:
No comments.
Sheet 15:
Station 587+50 -L- Right (Structure 1502): Investigate extending the proposed 24" pipe
and using a Preformed Scour Hole if the design criteria allows.
Station 588+00 -L- Right: Remove debris (existing detached FES) from stream.
Sheet 16:
Station 607+50 -L- Left (Structure 1610): Add drop box in proposed 24" pipe in order to
reduce velocity in the wetland.
Sheet 17:
No Comments.
Sheet 18:
Station 628+50 -L- Right (Structure 1808): Investigate realigning the proposed 24" pipe
with JS.

Sheet 19:
Station 642+00 -L- Right: Hydraulics explained that the wetland to the left will head up
and flow to the 30" pipe inlet.
Station 642+00 -L- Left: The Hydraulics Engineer explained that the gap between the
two 30" pipes will be maintained and that the proposed riprap will be placed between the
30" outlet and the wetland boundary.
Sheet 20:
No comments.
Sheet 21
Station 663+50 -L- Right: Place a note on Plans stating to tamp down riprap at outlet of
60" pipes or call for riprap on banks only.
Station 17+00 — 21+00 -Y32- Right: Hand clear wetland 5 feet from slope stake line.
Station 668+00 -L- Right: The Hydraulics Engineer pointed out that a portion of the
wetland shown on the Plans was actually a mowed lawn. NES stated that the wetlands on
this project will be confirmed.
Station 670+00 -L- Right (Structure 2129): Place inlet of proposed 30" pipe on grade in
order to avoid draining wetland.
Sheet 22
Station 677+00 -L- Right: Redesign Lateral "V" Ditch in order to reduce the velocity
going into the wetland.
Sheet 23
No impacts.
Meeting adjourned.
