SUBJECT: Harriet Henderson 404 Permit Application
Shoreline stabilization -Lake Summit
Henderson County DWQ No. 07-1975
Dear Mrs. Miller and Mr. McMillan:
Ms. Harriet Henderson requested a 404 Permit from the U.S. Army Corps of Engineers (ACOE).
Comments from the North Carolina Wildlife Resources Commission (Commission) are provided under
provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et seq.) and the Fish and Wildlife Coordination
Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
The applicant plans to stabilize with rock a failing seawall on Lake Summit.
If the work is authorized, then the Commission recommends that the permit be conditioned as follows to
help conserve fish and wildlife resources:
I. If practical, the stabilization work is completed while the lake is drawn-down.
2. Adequate sedimentation and erosion control measures are used to minimize the loss of disturbed soils
into the lake. Temporary or permanent herbaceous vegetation is planted on any bare soil within
fifteen (15) days of ground disturbance.
3. The lakebed is not excavated or otherwise disturbed except where necessary to bed rock. The
shoreline and the lakebed outside of the stabilization area is not disturbed for access or staging of
materials.
4. Any lame woody debris in the lakebed and in the path of the stabilization remains or is replaced and
secured to the shoreline at the completion of the project. Stumps, rocks or woody debns within the
are not removed.
5. If rock is placed against soil, then filter fabric is installed behind the rock to minimize wash-out.
6. The rock used is large quarry (class II or larger) or similar angular stone that is free of sediment and
other contaminants.

7. If a vertical wall is part of the stabilization, additional rock is placed at the base or toe of the lakeward
side of the wall to prevent undercutting and to enhance fish habitat.
8. The height of rock stabilization is no more than a few inches above the normal pool elevation.
However, a greater height may be acceptable if the erosion extends above the normal pool elevation.
In these cases, backfilling should be minimized (e.g. rock placed as close to eroded shoreline as
possible) and mimic the natural shoreline slope.
9. The stabilization does not extend into the lake any farther than necessary.. The stabilization follows
the existing shoreline of the lake.
10. Uncured concrete does not contact water since this can kill aquatic life.
11. Disturbance of shoreline vegetation, particularly trees and shrubs, is minimized.
Thank you for the opportunity to review and comment on this project. Pending availability of field staff,
the Commission may inspect the work site during or after construction. If there are any questions
regarding these comments, please contact me at 828/452-2546 extension 24.
Sincerely,
