The Division will accept this if you add a similar composition of rip rap for channel roughness between the spring and the
first stone drop.

Hi David,
Yes. Were you still planning on incorporating constructed riffles / rip rap in between the stone drop structures? If so, can
you show that on the plan? Can you confirm the rock in the stone drop structures has been sized for the stream /
velocity? Thanks,

David,
Yes. This type of structure, if designed and installed appropriately for the stream channel (comparable to the conceptual
plans attached), would be acceptable. Installing 3-4 of these structures with rip rap / constructed riffle in between the
structures would be an acceptable way to increase channel roughness and provide grade control.
The Division will want to see the structures and rip rap shown on the site plan. Please also include all necessary details /
plans so that the contractor can successfully install this. All materials used in the channel should be sized appropriately.
Coir matting and native veg seed should still be incorporated within the channel along with these new design features.

Would a series of 3 or 4 of these suffice? We could use some rip rap between them for the roughness issue.

David,
Rock check dams are not grade control structures. A rock check dam is not appropriate in this situation. The intent of the
grade control structure is to maintain design grade and prevent headcutting. A rock check dam will not perform this
function.
Please see the following resources for grade control structures:
https://www.bae.ncsu.edu/extension/srp/technical-resources/

Will channel roughness also be addressed? DWR believes increasing channel roughness will also be an important
component of maintaining stability in the channel bed.

Mr. Weikle,
Thank you for your reply.
Please see the NC Erosion and Sediment Control Planning and Design Manual, Chapter 8 - Appendices:
https://files.nc.gov/ncdeg/Energy%20Mineral%20and%2OLand%2OResources/Land%2OResources/Land%2OQuality/Erosi
on%20and%20Sediment%20Control%20Planning%20and%20Design%20Manual/Chapter%208/Chapter%208 rev%20Ma
y%202013.pdf
In Table 8.05d (on Page 8.05.9) for Maximum Permissible Velocities for Unprotected Soils in Existing Channels, the
maximum permissible velocity for ordinary firm loam is listed as 3.5 fps. The velocity you have calculated for the
proposed ditch is 4.89 fps. In light of this, the Division is concerned that erosion will occur in the ditch as it is currently
designed and transport sediment into downstream surface waters, thereby causing water quality violations

downstream. The Division will not issue a certification for a project that will cause downstream surface water quality
violations.
The Division would like to sees changes made to the proposed S1 impact to prevent this from happening. This could
include placing the S1 stream in a culvert. Alternatively, it could include making changes to the S1 stream channel
bottom (adding imported rock to create roughness and habitat while reducing velocity and erosion) and adding grade
control throughout the channel with —2 permanent structures. You might consider these as possible changes to create
greater stability in the stream channel and prevent erosion into downstream waters.
I spoke with Thomas Slusser today about my concerns and he has arranged a phone call tomorrow at 9am. I look
forward to discussing this with all involved.

Mr. Weikle,
Thank you for providing the Division with the revised drawings, calculations, and response letter. After speaking with
Mike Smith (DEMLR), I understand that you have provided DEMLR with revisions to the plan and associated calculations.
Please see my comments below:
• Please provide the Division with the most recent revised project plans. [15A NCAC 02H .0502 (b)(3)] SHIELD IS
MORE THAN HAPPY TO PROVIDE DWR WITH THE LATEST APPROVED DRAWINGS.
• Please provide calculations showing that all stormwater entering jurisdictional waters at station 0+60 will be at
non -erosive velocities (2.5 ft/second) for the 10 year storm event. SHIELD HAS ATTACHED CALCUATIONS
SHOWING THE PRE- OF POST -PROJECT FLOWS AT STATION 0+30. A ROUGHNESS COEFFICIENT OF 0.035 WAS
USED (OPEN CHANNELS— EARTH FAIRLY UNIFORM —SIDES CLEAN, COBBLE BOTTOM) FOR BOTH THE BEFORE
AND AFTER CONSTRUCTION. AS CAN BE SEEN, THE VELOCITY ACTUALLY DECREASES FROM 6.32 TO 4.89 DUE TO
THE PROPOSED WIDENING OF THE CHANNEL. IT SHOULD ALSO BE NOTED THAT BASED ON THE NATURAL SLOPE
OF THE CHANNEL AND THE ACTUAL DRAINAGE AREA FEEDING THE CHANNEL, A VELOCITY OF 2.5 FPS IS
IMPOSSIBLE TO PROVIDE.
Impact S1: Provide justification for the proposed stream channel dimensions based on reference reach
information or stable dimensions upstream and downstream of the impact area. Size the channel appropriately
to prevent future channel aggradation or degradation. [15A NCAC 02H .0506 (b)] THE CHANNEL WAS SIZED TO
GRADUALLY NARROW/TRANSITION FROM OUR UPPER DITCH WIDTH OF 10' TO THE NATURAL WIDTH OF THE
CHANNELATTHE PROPERTY LINE.
Pursuant to Title 15A NCAC 02H .0502(c), 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 by September 28, 2020, the
Division will be unable to approve the application and it will be returned.

On April 15, 2020, the Division of Water Resources (Division) received your application dated April 8, 2020 requesting a
401 Water Quality Certification from the Division for the subject project. On April 15, 2020, the application was placed
on hold while the Division determined whether an application fee was required. On May 8, 2020, the Division
determined that an application fee was not necessary. After initial review of the application, the Division has determined
that your application is incomplete and cannot be processed. The application is on hold until the following items are
addressed:
1. The plan proposes to excavate landfill material from within and below an existing intermittent stream. After
excavation is complete, a 10 foot wide ditch with a 5.2% slope will be graded to provide a channel for the
intermittent stream below an existing spring head (to remain undisturbed). The new ditch will be stabilized with
seed, straw, and coir matting. No grade control within the proposed ditch has been proposed.
a. The Division is concerned about stream channel stability within the proposed 10 foot wide, 5.2% slope
ditch. Please provide calculations showing that streamflow and stormwater flow will not degrade the
restored channel or downstream waters. [15A NCAC 02H .0506(b)(2) and (b)(3)]
2. Wattles are specified as 'Excelsior Wattle' in the drawing within the Sediment Wattle detail on sheet 9. All
wattles specified for placement in jurisdictional waters should be either a coir log or coir wattle and contain no
plastic netting or mesh. Please provide a specification sheet on selected product and update the plan
accordingly.
a. What is the timeline for maintaining and removing wattles from the stream after the project has
concluded? The wattles should not be left permanently.
10

b. Any sediment removed from behind wattles in the stream should be performed by hand with shovel and
bucket and spoils should be stabilized at least 30 feet from surface waters. Please provide a location on
the plan for spoils to be deposited and stabilized.
3. Is application of PAM proposed for all wattles? Use of PAM is not allowable on wattles in jurisdictional waters.
Please indicate this in the plan set.
4. The plan shows a silt fence outlet to be installed at the LOD within the channel of the intermittent stream.
a. This Office believes that the silt fence outlet can be revised to avoid and minimize the impacts to the
stream. Please provide an alternative to installing a silt fence outlet within the channel of the
intermittent stream. [15A NCAC 02H .0506(f) and (g)]
5. At what station do you expect to begin the pump around sequence? Please provide more detail on where / how
you intend to pump spring flow and stream flow (as well as any groundwater seepage) around the work area to
protect downstream waters.
Pursuant to Title 15A NCAC 02H .0502(c), 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 by August 1, 2020, the
Division will be unable to approve the application and it will be returned.
