Dear Ms. Murry and Mr. Karl:
The Division of Water Quality has reviewed your submittal for stream stabilization for the subject project. Your application
was not complete since it did not include adequate discussion regarding the use of "soil bioengineering" techniques vs.
natural channel design techniques. Specifically:
A) No specific explanation was provided to justify the use of toe and bed armoring of the channel. Generally these
methods are acceptable where geomorphic stability cannot be achieved. No numerical discussion of whether or not
stability could be achieved by providing stable cross sectional dimensions, longitudinal profile, and/or pattern
considering the streams ability to transport its bed load in equilibrium. The use of the proposed methods will have to
be justified if they are to be used in lieu of natural channel design techniques.
B) Please discuss the placement/spacing of the proposed in stream structures.
C) Little plan or typical detail was provided other than plan view. It is recommended that the following information be
provided in order to provide an adequate basis to review the project (if not already provided):
Basic Information for Plan Approval
1. Morphological measurements (see Appendix B) - not all of the measurements are applicable in every instance.
2. Typical stream cross sections -Typically, a riffle cross section and a pool cross section that includes the entire
flood prone area. The bankfull and flood prove area elevations should be indicated. Similarly, a riffle cross section of
the reference stream(s) should be provided.
3. Plan view - Scaled plans that show the location of the proposed (preferably with stationing) and the existing
stream. In most instances, the bankfull contours and flood prone area contours, in stream structures, bank
revetments/stabilization, channel plugs, planting plan, vegetation conditions, stormwater outlets, grade controls,
bridges, culverts, sewer lines, roads, fencing, and easement lines should also be provided.
4. Longitudinal Stream Profile -A scaled profile that indicates the thalweg , bankfull, and top of bank elevations
should be provided for the design and reference streams. In many cases it may also be necessary to show the
existing land elevations for the design stream.
5. Planting Plan - A planting and/or vegetation management plan should also be required. The plan should indicate
the extent, density, and species of plants to be provided.
6. In stream structure, bank revetment/stabilization, and stormwater outlet typicals - Detailed, typical plans should
be provided for all in stream structures, bank revetments or stabilization, and stormwater outlets. The typicals should
include materials and specifications as well as relative lengths, positions, and angles.
7. Sediment transport analysis - A sediment transport analysis should be provided based on the current, relevant,
accepted practices. The sediment transport analysis should be relevant to the stream bed load type and should
predict bed load transport equilibrium.
This information is needed by the Division in order for us to decide whether this project is. approvable.

Subject: Pre-Construction Notification Pursuant to a Nationwide
Permit No. 27
City of Charlotte Storm Water Services
Charleston/Monroe Watershed Improvement Project
Charlotte, North Carolina
Dear Mr. Dorney:
City of Charlotte Storm Water Services (CSWS) is submitting a Pre-Construction
Notification pursuant to Nationwide Permit No. 27 for the Charleston/Monroe
Watershed Improvement Project in Charlotte, North Carolina. This project proposes
to construct water quality improvements within two residential project areas. The
Charleston Drive Improvement Area (CDIA) is bisected by Independence Boulevard
(US-74), and is generally bound to the northwest by Sharon Amity Road and to the
south by Monroe Road. The Erinshire Road Improvement Area (ERIA) is located
approximately % mile south of the CDIA, and is generally bound to the northeast by
the Seaboard Coast Line Railroad, to the northwest by Sharon Amity Road, and to
the east by Doncaster Drive. Proposed activities will include enhancing channels to
improve channel dimensions, installing in-stream structures to control grade and
direction of flow, upgrading existing storm drainage infrastructure (i.e., pipe and
culvert replacement) to meet City storm drainage capacity standards, and installing
hard and soft stabilization to repair channel erosion. We are sending you seven
copies of this submittal in accordance with the notification requirements for NWP
No. 39, effective March 18, 2002.
If you have any questions concerning this project, don't hesitate to contact me at
[e-mail] or [phone]. Thank you for your attention to this
matter.
Sincerely,
5T"",, J. Karl
