SUBJECT: SRI 301, Bridge 75, Broadway Street, Blairs Fork (Spainhour) Creek,
TIP No. B-3933, Caldwell County
Although this is indicated as a North Carolina Department of Transportation (NCDOT) TIP
project, the Town of Lenoir is requesting federal 404 and state 401 approvals. Biologists with
the North Carolina Wildlife Resources Commission are familiar with habitat values in the area.
These comments are provided in accordance with the provisions of the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d) and the North Carolina
Environmental Policy Act (G.S. 113A-1 through 113A-10; NCAC 25).
The project will replace a 40.5 foot bridge at the existing location. The new structure will be a
55-foot, single span cored-slab bridge. Approaches will provide a 24-foot pavement with two
12-foot lanes with curbing and guttering. Each approach will be 150 feet in length (total of 300
feet). A traffic detour is proposed so Broadway Street will be closed until project completion.
Impacts from the new bridge will be limited to 64-feet of riprap protection. It is our
understanding that some streams in this area are listed as impaired [303 (d)] waters and that the
Santee Chub (Cyprinella zanema) NCSR is known from Lower Creek in Burke County.
Based on our review of the submittal and our knowledge of area habitats, we will not object to
the project. We recommend the following for the project:
1. Stringent erosion control measures should be installed where soil is disturbed and
maintained until project completion. Sediment and erosion control measures should
adhere to the design standards for sensitive watersheds (15A NCAC 4B .0024) due to
impaired waters in the area and rare species downstream.
2. Bridge removal should be accomplished so that no impacts occur to waters.
3. All work must be accomplished so that wet concrete and petroleum pollutants will not
contact stream water.
4. Post construction runoff water from the bridge and its approaches, including any
curbing and guttering discharges should be directed to vegetated areas, preferably
naturalized forested buffer zones to minimize stormwater issues to waters of the

State. Allowing sediment and erosion control measures to remain in place and
naturalize may provide additional protective measures.
5. To the extent practicable, state-of-the-art methodologies should be used for
stabilization. Regardless of the type of stabilization approved, natural channel base
flow stream dimensions should be provided under the bridge. Floodplain and stream
functions should not be diminished.
Thank you for the opportunity to review and comment on this project during the early planning
stages. If you have any questions regarding these comments, please contact me at 336-769-9453.
