Habitat Conservation Program
DATE: April 28, 2008
SUBJECT: Lake James Shoreline Stabilization Application, Bill Bradley, Lot 230, South
Pointe Subdivision, DWQ No. 20080579, Burke County
The applicant is requesting letters of concurrence from the North Carolina Wildlife Resources
Commission (NCWRC) to obtain a 404 permit from the U.S. Army Corps of Engineers. The
NCWRC has reviewed information provided by the applicant, and field biologists on our staff
are familiar with habitat values of the project area. These comments are provided in accordance
with 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 proposes to install riprap to stabilize 130 feet of eroding shoreline on Lake James.
Based on the information provided by the applicant, we will not object to the project provided
that the following non-prioritized conditions are followed:
1. The stabilization project should be done by barge with minimum class I (class II
preferred) riprap or rock instead of a wall. This size rock improves aquatic habitat
structure. We do not support the use of river rock as mining river rock causes
impacts to aquatic environments and destabilizes riparian zones by causing
unnatural geomorphic regime modifications. Natural fiber matting may be used
beneath the stone to reduce erosion and turbidity. Plastic matting should be
avoided as it entraps small animals. To the extent practicable, rock or stone
should be placed just above the high water mark and towards the lake five (5) to
six (6) feet to provide continuous aquatic edge habitat.
2. Stabilization work should occur from the water instead of the shore to minimize
buffer impacts. Existing wooded buffers should be preserved. Any Large
Woody Debris (LWD) should be maintained to the maximum extent practicable

to provide aquatic habitat. If relocated, the LWD must be securely anchored so
that it will remain where installed. We recommend that large boulders be placed
for fish habitat every 30 feet to provide enhanced aquatic habitat. Placement
should be accomplished so as not to cause hazardous conditions.
3. Stringent erosion control measures should be installed where soil is disturbed and
maintained until project completion. Temporary or permanent herbaceous
vegetation should be planted on all bare soil within ten (10) days of ground
disturbing activities to provide long-term erosion control.
4. Wide undisturbed shoreline buffers and natural vegetation should be maintained
to the extent practicable. Disturbed banks may be revegetated with silky
dogwood (Corpus amonum), silky willow (Salix sericea), tag alder (Alnus
serrulata), black willow (Salix nigra), and sycamore (Platanus occidentalis) or
other native plants to provide long term bank stability and stream shading. Note
that silky dogwood, silky willow and black willow can be planted as live stakes
collected during the dormant growing season. Cuttings should be randomly
planted and done on four (4) foot centers from the waters edge to the top of the
bank. Trees should be planted on ten (10) to twelve (12) foot centers. Banks in
these areas should also be seeded with an approved riparian/wetland seed mix or
temporary crop of wheat or rye.
5. The applicant should contact state and local planning and environmental
authorities to determine if permits are needed for the any buffer infringements or
impacts.
