Bridge No. 68 on SR-1718 (B-3318)
DWQ Project No. 020603
Caswell County
The Wetlands Unit received your response to the request for additional information dated June 18, 2002. Staff reviewed
the information provided and determined that additional information is necessary to establish that the proposed culvert will
not result in destabilization of South Hyco Creek. The required additional information is as follows:
This Office agrees with your statement that the introduction man-made controls would interfere with the natural equilibrium
of this stable stream system. This is why more information and additional measures have been requested by this Office to
ensure that the placement of the proposed culvert that restricts the existing floodway will not destabilize the stream.
General Water Quality Certification No. 3375 Condition No. 9 states in part:
"Design and placement of culverts including open bottom or bottomless arch culverts and other
structures including temporary erosion control measures shall not be conducted in a manner that may
result in aggradation, degradation or significant changes in hydrology of wetlands or stream beds or
banks, adjacent to or upstream and down stream of the above structures. The applicant is required to
provide evidence that the equilibrium shall be maintained if requested to do so in writing by DWQ.
Additionally, when roadways, causeways or other fill projects are constructed across FEMA-
designated floodways or wetlands, openings such as culverts or bridges must be provided to maintain
the natural hydrology of the system as well as prevent constriction of the floodway that may result in
aggradation, degradation or significant changes in hydrology of streams or wetlands."
The proposed changes to the stream morphology by the addition of the culvert may have a dramatic impact on the
stability of the stream, both up and downstream of the proposed impact, by_changing the channel's ability to transport its
bedload in its current state of equilibrium. Your letter of June 18, 2002 does not include enough information for this Office
to determine or predict whether or not the stream's ability to transport its bedload without aggrading or degrading can be
achieved with the current culvert design. This is of particular concern in waters classified as WS1I HQW (water supply 11,
high quality water). As such, you must demonstrate that the proposed culvert will not destabilize the stream and that
equilibrium will be maintained.
Additionally, based on the cross section drawing provided, it appears that the channel would be widened match the
elevation of the proposed outer (higher) sills as opposed to the outer culvert sill elevations being designed to match the
"bankfull" elevation of the existing channel. Also, the cross sectional area as well as the width and depth of the opening
below the "bankfull" elevation should match that of the existing channel below the bankfull elevation.
Finally, the application must include the commitment to use the erosion and sediment control practices and the planting
plan requested in our May 10, 2002 correspondence.
In any event, I would like to suggest that we schedule a meeting to discuss this matter as similar situations are likely to
arise. The aim of this meeting would be to develop specific protocols to address this situation so that we do not have to
put these (and similar) projects on hold in the future.

Dear Mr. Mills:
You have our approval, in accordance with the attached conditions and those listed below, to place fill material in
130 linear feet of streams for the purpose of replacing Bridge Number 68 on Bama Road (SR 1718) over South
Hyco Creek in Caswell County. The project shall be constructed in accordance with your application dated April
16, 2002, and your addendum dated December 11, 2002. After reviewing your application, we have decided that
this fill is covered by General Water Quality Certification Number 3375. This certification corresponds to the
Nationwide Permit 14 issued by the Corps of Engineers. In addition, you should acquire any other federal, state or
local permits before you proceed with your project including (but not limited to) Sediment and Erosion Control,
Non-Discharge and Water Supply Watershed regulations. This approval will expire with the accompanying 404
permit, unless otherwise specified in the Water Quality Certification.
This approval is valid solely for the purpose and design described in your application (unless modified below).
Should your project change, you must notify the DWQ and submit a new application. If the property is sold, the
new owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying
with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total
impacts to streams (now or in the future) exceed 150 linear feet, compensatory mitigation may be required as
described in 15A NCAC 211.0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the
conditions listed in the attached certification.
1.) Upon completion of the project, the NCDOT shall complete and return the enclosed "Certification of
Completion Form" to notify DWQ when all work included in the 401 Certification has been completed. The
responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the Division of
Water Quality upon completion of the project.
2.) The NCDOT shall strictly adhere to sediment and erosion control Best Management Practices as described for
High Quality Waters entitled."Design Standards in Sensitive Watersheds" (15A NCAC 04B .0024) throughout
design and construction of the project.
3.) Following completion of the construction, the areas where temporary impacts have been indicated shall be
restored to preconstruction contours and revegetated.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must
act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition that conforms
to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447,

Re: Permit Application for the proposed replacement of Bridge Number 68 on Bama Road (SR 1718)
over South Hyco Creek in Caswell County
DWQ No. 020603, TIP No. B-3318
Dear Mr. Mills:
The Division of Water Quality has reviewed your submittal for a 401 Water Quality Certification for the
aforementioned project. Review of your application revealed it lacking necessary information required for
making an informed permit decision. The permit application was deficient in the following areas:
The project as presently proposed calls for replacing a bridge with a culvert. The waters being
impacted are classified as WS II HQW. The application fails to provide any information regarding the
bankfull discharge or cross-sectional area, or stream profile information. Given that the project plans
to replace a bridge with a reinforced concrete box culvert, we need the requested information to assist
in the determination that the project will not result in a destabilization of the stream. In addition, please
assess the potential for an upstream and downstream cross vane to be constructed at the project site.
Also, provide the proposed design specifications for the cross vane installation. If you believe the
requested design changes are problematic, please provide additional information detailing the
engineering rationale, and provide an alternative design that provides for stream stability.
• The plan will need to incorporate a commitment to the use of sediment and erosion control Best
Management Practices as described for High Quality Waters entitled "Design Standards in Sensitive
Watersheds" (15A NCAC 04B .0024) throughout design and construction of the project.
• The plan will also need to incorporate a revegetation plan for the entire area located within the
construction limits of the project.
• Based on the bankfull discharge and cross-section information, NCDOT will need to design the culvert
sills such that the elevation of the tops of the high flow sills (outside sills) is equal to the project
elevation of the bankfull discharge. In addition, the low sill (inner box culvert) will need to match the
width/depth ratio of the low flow channel cross-section. The net result should be a series of sills that
match the bankfull cross-section as close as possible.

MEMORANDUM TO: Mr. J. M. Mills, P.E.
Division Engineer
FROM: J. L. Lindsey, P.E.
Hydraulics Manager of Maintenance Studies
SUBJECT: Additional Information Requested by DWQ
A field survey of Bridge 68 and South Hyco Creek was made on July 15, 2002, to
obtain additional information requested by Division of Water Quality. The additional
information included bankfull determination and associated geomorphic properties.
Bankfull determination and cross section data were taken approximately 200 ft. upstream
and 480 ft. downstream of the existing bridge.
The bankfull information is attached. Maximum depth was found to be about 3.2
feet with a bankfull width of 23 feet. The bankfull mean depth was calculated to be 2.3
feet. Stream grade control is not deemed necessary due to mild stream slope (0.0031
feet/foot) and substantial rock outcropping just upstream of the proposed culvert. Stream
grade control downstream is not deemed necessary due to mild stream slope and an
existing blowhold lined with a natural rock outcropping and large boulders.
Attached please find sketches for culvert bankfull bench sills to be used to insure
that bankfull dimensions will remain stable in the vicinity of the proposed culvert. These
bankfull bench sills located at the inlet and outlet of the proposed culvert should not
adversely affect the hydraulic performance of the culvert during higher frequency flood
events.
If further assistance is required, please contact this office.

Re: Replacement of Bridge No. 68 on SR-1718 on South Hyco Creek in
Caswell County, B-3318, DWQ 020603 a S 4
Your letter of 10 May 2002 requested that rock cross vanes be installed both up and down
stream of the proposed culvert. The stream hydraulics are controlled by flat bed gradient
of 0.2% and high natural tailwater elevations across a wide spectrum of storm
frequencies. Culvert conveyance is restricted by this hydraulic regime thereby posing no
stability problems for this reach of the stream.
The stream exhibits very stable conditions and introduction of man-made controls where
no channel degradation exist would interfere with the natural equilibrium of the system.
If NCDOT is required to install the requested cross vanes, the Department requires from
DENR (DWQ) a letter of indemnification which will "hold harmless" the Department
from any future claim of damage or demand for corrective action as result of the
requested action.
Your letter also requested high sills in the outside barrels to maintain flow in the center
barrel with a low sill to approximate bankfull conditions. The culvert design submitted
for 401 review already has this feature.
NCDOT's proposal for replacement of Bridge No. 68 Caswell County stands as on file in
your office under DWQ 020608. Thank you for the opportunity to address this situation

SUBJECT: Caswell County, Replacement of Bridge # 68 on Bama. Road (SR 1718) over South
Hyco Creek. P.O.C. # 6.503395, TIP # B-3318.
The North Carolina Department of Transportation (NCDOT) proposes to replace the existing
structurally deficient 1 @ 17'8, 1 @39' 5, 1 @ 16'5 1/2, 1 @ 17'9 1/2, timber Bridge with a 50-foot long
3 @ 12' X 10' Reinforced Concrete Box Culvert (RCBC) with Wingwalls. - The proposed RCBC is
the preferred structure due to cost and construction constraints. Bridge construction is prohibitive
due to cost constraints - the approximate cost of RCBC installation is $180,000, whereas the
approximate cost of bridge instillation is $300,000. Con Span construction is prohibitive due to the
absence of contractors having Con Span construction experience, and the presence of cost tracking
issues associated with cost increases that may occur due to delays between span deliveries and
installations.
Total permanent impacts will equal 90-linear feet. Permanent impacts will result from enclosure of
50-linear feet of channel, placement of 10-foot wing walls (to be located outside the channel), at
each end of the culvert, and placement of 10-linear feet of rip-rap energy dissipaters (within the
confines of the dewatered work area) at each end of the structure. Temporary impacts will equal 40-
linear feet. Temporary impacts will result from placement of ABC aggregate or a less intrusive
dewatering device within the stream to force flow into a diversion channel, and disturbance of stream
bank at the diversion channel entrance and exit. Temporary dewatering structures will extend a
maximum of 20-feet per end beyond the footprint of the proposed structure. The temporary
dewatering structures will be entirely removed upon completion of the project. The diversion
channel and entrance and exit will be graded to natural stream contour and protected by Coir fiber
immediately upon completion of the project.

Mitigation is not anticipated, as the impacts to any individual stream do not exceed 150 feet. The
project is located in a High Quality Water. The project will not impact an Essential Fisheries
Habitat. No Threatened or Endangered species were observed during a field survey conducted by
Len Smith, Tim Savidge, and Sharon Snider for species known to occur in Caswell County (See the
attached Endangered Species Review Sheet for further information). Historic compliance work to be
scheduled and concurrence with the Historic Preservation Office will be obtained if required. Direct
impacts will be minimized by burying the culvert 1-foot below streambed elevation and placing a 1-or
2-foot sill in the each of the barrels (see the attached cross-section) to maintain low flow and
facilitate aquatic life movement. Secondary impacts will be minimized by strict enforcement of Best
Management Practices for Bridge Demolition Removal and Protection of Surface Waters,
restrictions against the staging of equipment in or adjacent to waters of the US, and coordination
with the Division Environmental Officer.
The NCDOT anticipates that the pipe placement will be authorized under Nationwide Permit (NWP)
14 and the dewatering operation will be authorized under NWP 33. This application is intended as a
request for formal written authorization from the USACE for dewatering activities occurring under
NWP 33. This application is also intended as request for written authorization from the NC Division
of Water Quality to place the RCBC in the channel under General Water Quality Certificate # 3375
(NWP 14). Enclosed please find the project site map and the pre-construction notification form for
the above referenced project. Construction is anticipated to begin spring of 2003 and take 4 months
to complete.
If you have any questions or need any additional information, please contact Dennis Johnson at (336)

Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The structurally deficient bridge must be replaced to ensure safety. The proposed RCBC is the
preferred structure due to cost and construction constraints. Bridge construction is prohibitive
due to cost constraints - the approximate cost of RCBC installation is $180,000, whereas the
approximate cost of bridge instillation is $300,000. Con Span construction is prohibitive due to
the absence of contractors having Con Span construction experience, and the presence of cost
tracking issues associated with cost increases that may occur due to delays between span
deliveries and installations Direct impacts will be minimized by burying the culvert 1-foot
below streambed elevation and placing a 1-or 2-foot sill in the each of the barrels (see the
attached cross-section) to maintain low flow and facilitate aquatic life movement. Secondary
impacts will be minimized strict enforcement of Best Management Practices for Bridge
Demolition Removal and Protection of Surface Waters restrictions against the staging of
equipment in or adjacent to waters of the US and coordination with the Division Environmental
Officer.

Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
No mitigation is anticipated, as impacts are less than 150 feet. In addition, no Wetlands,
Outstanding Resource Waters or federally protected species occur in the project area. South
Hyco Creek is located in a Water Supply-II watershed.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at httl2://h2o.enr.state.nc.us/wm/index.litm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:
Amount of stream mitigation requested (linear feet): N/A
Page 6 of 8
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
VIII. Environmental Documentation (DWQ Only)
Does the project involve an expenditure of public funds or the use of public (federal/state/local)
land?
Yes ® No ?
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No ?
IX. Proposed Impacts on Riparian and Watershed Buffers (DWQ Only)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ? No ® If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Zone* Impact

Dear Mr. Henderson:
June 24, 2002
Subject: Bridge No. 68 on SR-1718 (B-3318)
DWQ Project No. 020603
Caswell County
The Wetlands Unit received your response to the request for additional information dated June 18, 2002. Staff reviewed
the information provided and determined that additional information is necessary to establish that the proposed culvert will
not result in destabilization of South Hyco Creek. The required additional information is as follows:
This Office agrees with your statement that the introduction man-made controls would interfere with the natural equilibrium
of this stable stream system. This is why more information and additional measures have been requested by this Office to
ensure that the placement of the proposed culvert that restricts the existing floodway will not destabilize the stream.
General Water Quality Certification No. 3375 Condition No. 9 states in part:
"Design and placement of culverts including open bottom or bottomless arch culverts and other
structures including temporary erosion control measures shall not be conducted in a manner that may
result in aggradation, degradation or significant changes in hydrology of wetlands or stream beds or
banks, adjacent to or upstream and down stream of the above structures. The applicant is required to
provide evidence that the equilibrium shall be maintained if requested to do so in writing by DWQ.
Additionally, when roadways, causeways or other fill projects are constructed across FEMA-
designated floodways or wetlands, openings such as culverts or bridges must be provided to maintain
the natural hydrology of the system as well as prevent constriction of the floodway that may result in
aggradation, degradation or significant changes in hydrology of streams or wetlands."
The proposed changes to the stream morphology by the addition of the culvert may have a dramatic impact on the
stability of the stream, both up and downstream of the proposed impact, by changing the channel's ability to transport its
bedload in its current state of equilibrium. Your letter of June 18, 2002 does not include enough information for this Office
to determine or predict whether or not the stream's ability to transport its bedload without aggrading or degrading can be
achieved with the current culvert design. This is of particular concern in waters classified as WSII HQW (water supply II,
high quality water). As such, you must demonstrate that the proposed culvert will not destabilize the stream and that
equilibrium will be maintained.
Additionally, based on the cross section drawing provided, it appears that the channel would be widened match the
elevation of the proposed outer (higher) sills as opposed to the outer culvert sill elevations being designed to match the
"bankfull" elevation of the existing channel. Also, the cross sectional area as well as the width and depth of the opening
below the "bankfull" elevation should match that of the existing channel below the bankfull elevation.
Finally, the application must include the commitment to use the erosion and sediment control practices and the planting
plan requested in our May 10, 2002 correspondence.
In any event, I would like to suggest that we schedule a meeting to discuss this matter as similar situations are likely to
arise. The aim of this meeting would be to develop specific protocols to address this situation so that we do not have to
put these (and similar) projects on hold in the future.

Re: Permit Application for the proposed replacement of Bridge Number 68 on Bama Road (SR 1718)
over South Hyco Creek in Caswell County
DWQ No. 020603, TIP No. B-3318
Dear Mr. Mills:
The Division of Water Quality has reviewed your submittal for a 401 Water Quality Certification for the
aforementioned project. Review of your application revealed it lacking necessary information required for
making an informed permit decision. The permit application was deficient in the following areas:
The project as presently proposed calls for replacing a bridge with a culvert. The waters being
impacted are classified as WS II HQW. The application fails to provide any information regarding the
bankfull discharge or cross-sectional area, or stream profile information. Given that the project plans
to replace a bridge with a reinforced concrete box culvert, we need the requested information to assist
in the determination that the project will not result in a destabilization of the stream. In addition, please
assess the potential for an upstream and downstream cross vane to be constructed at the project site.
Also, provide the proposed design specifications for the cross vane installation. If you believe the
requested design changes are problematic, please provide additional information detailing the
engineering rationale, and provide an alternative design that provides for stream stability.
• The plan will need to incorporate a commitment to the use of sediment and erosion control Best
Management Practices as described for High Quality Waters entitled "Design Standards in Sensitive
Watersheds" (15A NCAC 04B .0024) throughout design and construction of the project.
•. The plan will also need to incorporatea revegetation plan for the entire area located within the
construction limits of the project.
• Based on the bankfull discharge and cross-section information, NCDOT will need to design the culvert
sills such that the elevation of the tops of the high flow sills (outside sills) is equal to the project
elevation of the bankfull discharge. In addition, the low sill (inner box culvert) will need to match the
width/depth ratio of the low flow channel. cross-section. The net result should be a series of sills that
match the bankfull cross-section as close as possible.

Therefore, pursuant to 15A NCAC 2h .0507(a)(5), Nye will have to place the permit application on hold
until we are supplied the necessary information. Furthermore, until the information is received by the NC
Division of Water Quality, we request (by copy of this letter) that the US Army Corps of Engineers place
the permit application on hold.
Hopefully, we can work together to expedite the processing of your permit application. If you have any
questions or require additional information, please contact John Hennessy at 919-733-5694.
