DATE: October 22, 2009
SUBJECT: Review of an application for Frank Boncimino, Lot 1220, The Point Subdivision,
Lake Norman, DWQ No. 20091086, Iredell County
The applicant is requesting a letter 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 river rock to stabilize approximately 114 linear feet of shoreline
on Lake Norman. A site visit has not been conducted by our agency. Accordingly, these
comments are provided based on information provided in the submittal package.
Based on the information provided and our knowledge of the project area, we will not object to
the project provided that the following conditions are followed:
The stabilization project should be done with minimum class I (class II preferred)
riprap. This size rock improves aquatic habitat structure. We do not support the
use of river rock. In channel mining of river rock causes direct impacts to aquatic
species as well as it disrupts aquatic environs by causing geomorphic and biologic
modifications. River rock is subject to more slippage than more irregularly
shaped quarry rock. Fabric matting may be used beneath the stone to reduce
erosion and turbidity. 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 or

further to provide continuous aquatic edge habitat. To improve aquatic habitat
values, a large boulder is recommended a minimum of every thirty (30) feet of
stabilized shoreline. Placement of boulders should be accomplished in a manner
that safety is not compromised.
2. Stabilization work should occur from the water instead of the shore to minimize
buffer impacts. Any existing wooded buffers should be preserved.
3. 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.
4. 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.
5. 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 be seeded with a temporary crop of wheat or oats.
6. The project should comply with NC Division of Water Quality and local planning
authority buffer provisions.
Thank you for the opportunity to review and comment on this project. If you have any questions
regarding these comments, please contact me at 336-769-9453.
