SUBJECT: Review of NCDOT's application for a Section 404 permit to replace Bridge No.
244 over Glade Creek on SR 1422 (Sheriffs Road), Alleghany County, North
Carolina.
The North Carolina Department of Transportation has submitted an application to obtain a
Section 404 Permit from the U.S. Army Corps of Engineers. Staff biologists with the North
Carolina Wildlife Resources Commission have reviewed the information provided. These
comments are provided in accardance with the provisions of the state and federal Environmental
Policy Acts (G.S. 113A-lthrough 113-10; 1 NCAC 25 and 42 U.S.C. 4332(2)(c), respectively),
the Clean Water Act of 1977 (33 U.S.C. 466 et seq.), the Endangered Species Act (16 U. S. C.
1531-1543; 87 Stat 884), and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended;
16 U.S.C. 661-667d), as applicable.
The NCDOT proposes to replace Bridge No. 244 over Glade Creek on SR 1422 (Sheriffs Road)
with a new single span bridge at the same location. Permanent stream impacts total 8 linear feet
for riprap and temporary impacts total 47 lf due to dewatering. Glade Creek supports Brown
Trout in the project area, therefore a moratorium prohibiting in-stream work and land disturbance
within the 25-foot trout buffer should apply from October 15 to April 15 to protect the egg and
fry stages of trout. Sediment and erosion control should adhere to the Design Standards in
Sensitive Watersheds.
NCWRC will not object to the issuance of the Section 404 permit provided that the following
conditions are implemented:

1. In-stream work and land disturbance within the 25-foot wide buffer zone are prohibited
during the trout spawning seasons of October 15 through April 15 to protect the egg and
fry stages of trout.
2. Sediment and erosion control measures shall adhere to the Design Standards in Sensitive
Watersheds and be strictly maintained until project completion.
3. Herbaceous vegetation shall be planted on all bare soil as soon as possible following the
completion of permanent or temporary ground disturbing activities to provide appropriate
long-term erosion control.
4. Tall fescue and straw mulch shall not be used in riparian areas. We encourage NCDOT
to utilize onsite vegetation and materials for bank stabilization when practicable. Erosion
control matting shall be used on steep slopes and for establishing permanent vegetation in
riparian areas. The matting shall be well anchored with staples or wooden stakes and,
whenever possible, include live stakes of native trees. Matting in riparian areas should
not contain plastic mesh, which can entangle and trap small animals.
5. Storm water should be directed to buffer areas or retention basins and should not be
routed directly into the waterway.
6. The natural dimension, pattern, and profile of the waterway above and below the crossing
should not be modified by widening the channel or changing the depth of the waterway.
7. Removal of vegetation in riparian areas should be minimized. Native trees and shrubs
should be planted along the banks, as appropriate to the setting, to reestablish the riparian
zone and to provide long-term erosion control.
Grading and backfilling should be minimized, and tree and shrub growth should be
retained, if possible, to ensure long term availability of shoreline cover for fish and
wildlife.
9. Where practicable, riprap placed for bank stabilization should be limited to the banks
below the high water mark, and vegetation should be used for stabilization above the high
water elevation.
10. If concrete will be used during construction, work must be accomplished so that wet
(uncured) concrete does not contact surface waters. This will lessen the chance of
altering the water chemistry and causing a fish kill.
1 l. Discharging hydroseeding mixtures and washing out hydroseeders and other equipment
in or adjacent to surface waters is prohibited.
12. Heavy equipment should be operated from the bank rather than in the channel whenever
possible in order to minimize sedimentation and reduce the likelihood of introducing

other pollutants into the waterway. All mechanized equipment operated near surface
waters should be inspected and maintained regularly to prevent contamination of surface
waters from fuels, lubricants, hydraulic fluids or other toxic materials.
