Subject: DWR 17-0856 Chestnut Park Stream Restoration
The Division of Water Resources (DWR) has performed a review of a 401 Water Quality Certification application dated
June 19, 2017, and received by the Division of Water Resources (Division) on July 21, 2017. The Division has determined
that your application is incomplete and cannot be processed. The application is on -hold until additional information
has been received.
1. Provide the proposed longitudinal slope and proposed typical cross-sections with dimensions including channel
cross-sectional area, bottom width, top width, streambank slopes, and channel depth. Provide justification for
the proposed channel dimensions based on reference reach information or stable dimensions upstream or
downstream of the impact area. Size the channel appropriately to prevent future channel aggradation or
degradation. [15A NCAC 02H .0506 (b)]
2. Provide justification for the proposed bank armoring with large boulders and describe why the project goals
cannot be met with streambank grading, bankfull bench creation, and bioengineering practices. [15A NCAC 02H
.0506 (b)]
3. Provide construction details/plans of proposed in -stream structures, type of structure (sills, cross vanes, j -hooks,
etc.), and their locations (material to be used, material sizes, elevations, lengths, widths, heights, grading
requirements, stream bank tie-ins, etc.). Size the appropriate structures to maintain the proposed cross-
sectional dimensions to prevent over -widening the stream channel. [15A NCAC 02H .0506 (b)]
4. If the proposed project includes modifying the existing pattern of the stream (e.g., sinuosity), provide the
proposed pattern view with justification for the modifications based on reference reach information or stable
pattern data upstream or downstream of the impact area. [15A NCAC 02H .0506 (b)]
5. Provide planting details/plans (plant types, plant sizes, proposed plant list, location of typical plants, plant
spacing, coir matting placement, etc.) [15A NCAC 02H .0506 (b)]
Pursuant to Title 15A NCAC 02H .0502, the applicant shall furnish all of the above requested information for the proper
consideration of the application. If all of the requested information is not received within 45 calendar days of receipt of
this email, the DWR will be unable to approve the application and it will be returned. The return of this project will
necessitate reapplication to the DWR for approval, including a complete application package and the appropriate fee.
Please contact me if you have any questions or concerns.
