This project consists of a portion of the Clayton Bypass (US 70). The meeting began at 3:20.
1. Bridges at Station 109+56 -L2-: The bridges were widened to span the riparian buffers. No
scuppers are allowed directly over the buffer zone or surface water. The structure engineers
(Lonnie Brooks and Theo Beach) will investigate options to avoid having bent columns. within
the tops of bank for the right lane bridge. The left lane bridge did not have this problem.
Constructability should not be an issue.
2. Grass Swales: Although level spreaders were considered first, grass swales were used for
treatment in areas with topographical restraints. These restraints included adjacent wetlands,
steep slopes and confined areas resulting from proposed fill slopes. All swales will have the
calculations include on the permit drawings showing adequate treatment before entering
streams.
3. Pond on sheet 7: Once the isolated pond is drained, the new reach formed in the pond floor will
have buffers. John Hennessy will investigate how this needs to be addressed.
4. Equalizer Pipe: Remove riprap at outlet of equalizer pipe on sheet 7 and sheet 20.
5. Culvert on Sheet 9: No riprap is allowed in channel bottom.
6. Coopers Branch: a 12'x 8' wildlife crossing will be added in floodplain. Look at pulling PFSH
out of wetlands.
7. Sheet 17: Move the proposed bore and jack pipe closer to the existing 900mm pipe to
consolidate impacts.
8. Sheet 26A:Additional area needs to be investigated for wetlands.
The meeting was adjourned at 5:15.
