Brenna,
I have reviewed the scoping letter, vicinity map, and aerial for the replacement of Bridge No. 176 over Slocum Creek on
SR 1763 in Craven County (B-4488). I have the following comments:
1. In general, for all bridge replacements, EPA prefers structures that span the waterbody. Efforts should be made to
also span the adjacent wetlands.
2. EPA recommends that this bridge be replaced in the same location. It appears from the vicinity map and aerial
photograph that road closure and an off-site detour are feasible for this project.
3. Bridge supports should not be placed in the stream, if possible.
4. Bridge deck drains should not discharge directly into the stream, and stormwater should be pre-treated prior to
discharge to a stream or wetland.
Thank you for the opportunity to comment on this project. Have a good weekend,
Kathy Matthews
