APPROVAL of 401 Water Quality Certification
Dear Mr. Wyatt:
You have our approval, in accordance with the attached conditions, to place fill in 90 linear feet of Buffalo Creek in
order to construct proposed storm drainage improvements to the Merritt Drive culverts in Guilford County, as described in
your application received by the Division of Water Quality on December 18, 2001, and in additional correspondence
received June 8, 2001. After reviewing your application, we have determined that this fill is covered by General Water
Quality Certification Number 3289 which can be viewed on our web site at http://h2o.enr.state.nc.us/ncwetlands . This
Certification allows you to use Nationwide Permit Number 14 when it is issued by the U.S. Army Corps of Engineers. In
addition, you should get any other federal, state or local permits before you go ahead with your project including (but not
limited to) Sediment and Erosion Control, Non-Discharge and Water Supply Watershed regulations. Also this approval will
expire when the accompanying 404 permit expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new application for a new certification. If the property is
sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for complying
with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may
be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed in
the attached certification.
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 which conforms to
Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh,
N.C. 27611-7447. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have
any questions, please telephone Jennifer Frye in our Winston-Salem Regional Office at [phone] ext. 275 or Cyndi
Karoly in our Central Office at 919-733-9721.

Staff report completed. They have re-designed such that the additional
culvert that they have applied for is now to be installed above baseflow
(there are 3 existing box culverts carrying baseflow). They have also
done away with the excessive rip rap. I put on the staff report that
the impacts are for 90 if (the culvert impacts) and did not include the
up- and down-streambank stabilization, since it is supposed to be
vegetation. I was not quite sure if this was the correct assessment of
the impacts.

Merritt Drive Culvert Improvements
DWQ Project # 00 1562
Guilford County
Dear Mr. Wyatt:
The Division of Water Quality has reviewed your plans for the discharge of fill material
into approximately 390 linear feet of Buffalo Creek, Class C NSW waters, Cape Fear River
Basin, for the purpose of culvert installation and streambank stabilization. Insufficient evidence
is present in our files to conclude that your project must be built as planned in waters and/or
wetlands in accordance with 15A NCAC 2H.0506. Therefore, unless modifications of the
proposal are made as described below, we will have to move toward denial of your 401
Certification as required by 15A NCAC 2H.0507(e) and will place this project on hold as
incomplete until we receive this additional information. We are requesting (by copy of this letter)
that the U. S. Army Corps of Engineers place your project on administrative hold.
(1) Please provide us with information supporting your position that states your
project must be constructed as planned and that you have no practicable
alternative to placing fill in these waters and/or wetlands. Documentation such as
maps, narratives, economic analyses, that you can supply to address alternative
designs for your project may be helpful in our review of your 401 Certification
request.
(2) Please provide documentation detailing your position that the project has been
designed such that adverse impacts to surface waters have been minimized and
existing uses have been protected to the best of your ability.
Merritt Drive
Page 2
(3) Additional information is also needed regarding the proposed 84" culvert.
Specifically, will this culvert be installed at the same elevation as the existing box
culverts and conveying base flow or at a higher elevation to capture only
stormwater flow? Is it possible to reduce the linear footage of impact associated
with streambank stabilization by utilizing bioengineering methods instead of rip-
rap?
(4) Since your proposed impacts are greater than 150 linear feet, the project will also
require compensatory mitigation as described in 15A NCAC 2H.0506(h). Your
mitigation proposal is insufficient since none was proposed. If impacts (culvert
plus rip-rap) were reduced to less than 150 linear feet, compensatory mitigation
would not be required by the Division of Water Quality.
Please respond, in writing, both to this Office and to John Dorney, 2321 Crabtree
Blvd., Raleigh, NC 27604-2260 within three weeks of receipt of this letter outlining your
intent to proceed with this project or withdraw your application. If you wish to proceed,
please address the items listed above.
If you have any questions regarding this matter, please contact Mrs. Jennifer Frye or me
at [phone].
Sincerely,
Larry D. Coble

Dear Mr. Dorney:
Enclosed please find the additional information you requested for your review of the
above referenced project.
1. Does this project involve replacement of an existing bridge with a culvert, or
is it a new crossing?
This is an existing crossing over Buffalo Creek along Merritt Drive. In
recent years, the cross-section of Merritt Drive has been raised, thereby,
raising the base flood elevation. The purpose of this project is to get
the base flood level back to its original elevation. Currently there is a
triple box culvert in place in Buffalo Creek. We are proposing to add an
84-inch RCP culvert to lower the flood elevation.
2. Please provide information and calculations used to determine the culvert
diameter and length chosen. Have you determined whether or not this
culvert will destabilize upstream or downstream portions of Buffalo Creek?
Please find enclosed the flood study output files for your information.
The calculations show the velocity downstream of the culvert will
increase from 4.3 fps to 5.4 fps following the culvert installation. We
feel the protection of the channel will be provided by the rip-rap lining
specified.
3. Please provide information on any proposed armoring upstream and
downstream of the proposed culvert.
In the areas where the stream is to be widened, thereby, disturbing the
existing banks, we are proposing to line the proposed banks with class
Mr. John Dorney
NCDENR May 7, 2001 Page 2
II rip-rap. The grading on the upstream side of the culvert has been
reduced to minimize stream impacts. The revised sheet is attached.
4. Please list the total linear distance of stream impact proposed, including the
linear feet of stream to be filled by the culvert (not simply the culvert length)
as well as rip-rap or other armoring techniques.
The total length of stream to be directly impacted by this project is 300
linear feet and does not include the culvert length. See No. 1.
Should you have any questions or require additional information, please do not hesitate
to contact our office.
Very truly yours,

Dear Mr. Wyatt:
On December 18, 2000, the NC Division of Water Quality received your application for a 401 Water
Quality Certification to place a culvert in Buffalo Creek in Guilford County. In order to complete our review
of this project, the following information is needed:
1. Does this project involve replacement of an existing bridge with a culvert, or is it a new crossing?
2. Please provide information and calculations used to determine the culvert diameter and length
chosen. Have you determined whether or not this culvert will de-stabilize upstream or downstream
portions of Buffalo Creek?
3. Please provide information on any proposed armoring upstream and downstream of the proposed
culvert.
4. Please list the total linear distance of stream impact proposed, including the linear feet of stream to
be filled by the culvert (not simply the culvert length) as well as rip-rap or other armoring
techniques.
Until this information is received, I will request (by copy of this letter) that the Corps of Engineers place
this project on hold. Also, this project will be placed on hold for our processing due to incomplete
information (15A NCAC 2H .0507(h)). I can be reached at [phone].

Attn: Mr. Gregory L. Hughes, PE
Management Engineering and Technical Services Division
Dear Mr. Hughes:
Thank you for your letter of July 6, 1998. We have enclosed additional information as outlined in the
responses to each of the comments included in your letter.
Comment 1: Please submit Form 7, entitled "Bridge/Culvert Form" (one form per new/revised
bridge/culvert).
Response 1: We have enclosed a completed "Bridge/Culvert Form" for the "Corrected
Effective Model ; the "Existing/Pre-Project Model" and the "Revised/Project
Model'%
Comment 2: Please submit certified topographic mapping of the 1 % (100-year) and 0.26/o (500-
year) annual chance floodplains and floodway for South Buffalo Creek, representing
existing and proposed conditions. This mapping should include the locations and
alignments of cross sections used in the HEC-2 models.
Response 2: We have enclosed topographic mapping of the 1% (100 year) and 0.2% (500-year)
annual chance floodplains and floodway for South Buffalo Creek. We have
enclosed one map, showing the corrected effective and post project 100-year--
and 500-year floodplains. The locations of our surveyed cross-sections are also
shown on the maps.
Comment 3: The submitted HEC-2 hydraulic models for South Buffalo Creek should extend
upstream of the project area until the revised Base (1% annual chance) Flood
Elevation (BFE) coincide with those shown in the effective HEC-2 model within 0.5
foot. Please submit both disk and paper copies of the extended hydraulic modeling.
Gregory L Hughes, PE
Dewberry & Davis November 30, 1998 Page 2
Response 3: We have extended the hydraulic modeling up to section 94000. The difference at
this section between the "corrective effective" base- flood levels and the
"Existing/Pre-Project" flood levels is 0.2 vertical feet.
Comment 4: The submitted information on Exhibit No. 1 indicates that the culvert invert elevation A,
771.3 feet, which does not agree with the invert elevation of 770.81 feet used in the
pre-project and post-project HEC-2 models. A note on Exhibit No. 1 states that the City
of Greensboro vertical datum is 0.77 foot higher than NGVD; nevertheless, a
mismatch exists between the map and HEC-2 modeling. Please Investigate this
discrepancy and revise and resubmit the HEC-2 models and/or supporting data as
appropriate.
Response 4: We have field verified the Invert elevations and each model has been revised
accordingly. The invert elevations of each of the box culverts varied slightly.
Since HEC-2 does not provide a location to Input various Inverts the average
elevation of each of the three barrels was used In the hydraulic models.
Comment 5: The HEC-2 models indicate that the proposed Merritt Drive culvert addition will cause
BFE increases for South Buffalo Creek. Therefore, please submit the following items to
comply with NFIP regulations Paragraph 65-12(a):
a. an evaluation of alternatives that would not result in any BFE increases,
demonstrating why these alternatives are not feasible;
b. documentation of individual legal notice to all impacted property owners,
explaining the effects of the project on their property; and
c. certification that no structures will be Impacted by the increased BFEs due to
the proposed culvert addition.
Response 5: The addition of the proposed culvert will correct the potential for Increased base
flood levels resulting from Improvements to Merritt Drive. Merritt Drive was
widened to alleviate congestion and improve the safety of the traveling public. To
properly design the road the existing superelevation was extended causing an
Increase In the controlling elevation of the road profile. The culvert addition will
return the base flood elevations to the original "Corrected Effective Elevations"
shown in the attached documentation. As shown on the mapping a structure
adjacent to Section 94000 has a finished floor below base flood levels calculated
in the "Effective and Corrected Effective" models. The proposed additional culvert
at Merritt Drive will maintain the same base flood levels calculated In the
"Corrected Effective Model". With the additional culvert no Increases in the base
flood levels will occur and notification to property owners would occur only to
inform them of a correction In the base flood elevations.
Comment 6: Please submit water-surface profiles, annotated mapping, and any other supporting
data to reflect any changes due to the concerns listed above.
Gregory L Hughes, PE
Dewberry & Davis November 3o, 1998 Page 3
Response 6: We have enclosed hard copies and disk copies of each of the following -
hydraulic models:
• Duplicate Effective
10-50-100-500 year events (File Merr1026.hc2)
100 year and 100 year encroachment (File encroach.hc2)
