APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS, WRP
Mr. Steve Stroud
Centennial Authority
1520 Blue Ridge Road
Suite 201
Raleigh, NC 27607
Dear Mr. Stroud:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
material in 380 linear feet of waters for the purpose of constructing a road crossing at Centennial Arena over
Richland Creek at Edward's Mill Extension in Wake County, as you described in your application dated April 28,
1998 and your original application dated February 3, 1998. After reviewing your application, we have decided that
this fill is covered by General Water Quality Certification Number 3103. This certification allows you to use
Nationwide Permit Number 14 when the Corps of Engineers issues it. 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, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations. This approval will expire
when the accompanying 404 or C.AMA 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 except as
modified below. 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 this 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 and
any additional conditions listed below.
1. Stormwater shall be managed as described in the February 6, 1998 plan prepared by Kimley-Horn and
Associates and approved by DWQ on March 13, 1998.
2. A planting plan must be submitted to DWQ for written approval for the riparian buffer along
Richland Creek.
We understand that you have chosen to contribute to the Wetland Restoration Program in order to compensate
for these impacts to wetlands and/or streams. In accordance with 15A NCAC 2R .0500, this contribution will
satisfy our compensatory mitigation requirements under 15A NCAC 2H.0506(h). According to 15A NCAC 2H
.0506(h), 155 feet of restoration will be required. Until the Wetland Restoration Program receives and clears your
check (made payable to: DEHNR - Wetland Restoration Program), wetland or stream fill shall not occur. Mr. Ron
Ferrell should be contacted at 919-733-5083 ext. 358 if you have any questions concerning the Wetland Restoration
Program. You have one month from the date of this Certification to make this payment. For accounting purposes,
this Certification authorizes the fill of 380 linear feet of streams in 030402 river and subbasin and 380 feet of
riparian restoration are required. Please be aware that the wetland Restoration Program (WRP) rules
require rounding of acreage amounts to one-quarter acre increments (15A 2R.0503(b)). 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.

Subject: Centennial Authority/ESA
Stormwater Ponds
DWQ No. 980100
Wake County
Please find the attached final plans for the stormwater management ponds at the
ESA. The.plaus supportrthe:engineer's claims in regard to the surface areas. The surface
area of Basin 3 is 5% undersized and the temporary pool volume is 8% undersized to
treat the drainage area. However, considering the difficult history of this project, I
recommend that the plans dated November 29, 1998, for Basin 2 be approved based on
the memo from Ray Cox dated February 19, 1998, and that the plans dated October 5,
1998, for Basin 3 be approved.

Re: ESA Stormwater Basins
Dear Todd:
Attached are copies of stormwater basin 2 and 3 as we discussed in our telephone
messages. We have revised the design of basin 2 to yield a surface area of 0.45 ac. as
requested and as shown in our earlier submittal. This new basin design, with a surface
area of .45 acres, is in fact a larger basin because we have increased the depth to seven
feet rather than the four feet as previously submitted. This increased treatment capacity
should more than compensate for a reduction in the surface area of basin 3.
Basin 3 as proposed has a surface area of 10,627 feet or 0.24 acres. As noted in John's
letter of October 16, 1998, we had originally proposed a surface area of 0.35 ac. To
revise the plans for this basin to obtain the 0.35 acres will require that we remove the
existing earth embankment, remove trees closer to the creek and build a new
embankment. This makes little water quality sense since retaining trees close to streams
has been identified as a best management strategy for the Neuse River.
As you are aware, I have talked with John about our latest proposal. He was in general
agreement with the concept of getting the .45 ac. in basin 2 with increased depth and
removal efficiency and accepting the 0.24 ac. in basin 3 rather than removing a perfectly
good structure to get 1/10th of a acre surface area.
Hopefully, the Division can agree to this proposal and you can issue a letter stating such
immediately. I sincerely appreciate the manner that you and John have worked with us
on this and please call me immediately if you have any questions.
Sincerely yours,
Kimley-Horn and Associates

Dear Mr. St. John:

Pursuant to our discussions, I have enclosed a copy of the revised stormwater calculations
related to the two stormwater basins that are proposed for the Entertainment and Sports
Arena complex. The basins are required as a condition of the 401 certification issued for
the culvert construction in Richland Creek. The basin configuration was amended from
that originally proposed, however, as you will see in the accompanying calculations the
design criteria for stormwater management pond surface requirements are met with the
new configuration.
Please review and process as soon as possible so that we can get the plans out for bidding
purposes.
Thank you for your help and please call if we need to discuss.
Very truly yours,
Kimley-Horn and Associates

Basin 2
90 % Impervious
Area to be treated = 8.69 ac.
Depth of Permanent Pool = 4.0 ft.
SA/DA = 2..81
SURFACE AREA REQUIRED = 8.69X2.81/100
= 0.244 ac.
= 10,642 sq. ft.
TOTAL AREA PROVIDED = 12, 683 sq. ft.
Therefore: Basin 2 meets DWQ stormwater requirements.
Basin 3

Area to be treated = 10.7 ac.
Depth of permanent Pool -= 5.0 ft.
SA/DA = 2.42
SURFACE AREA REQUIRED = 10.7 X 2.42/100

11,238 sq.ft.
TOTAL AREA PROVIDED = 10,627 sq.ft.
Therefore: Basin 3 substantially meets DWQ stormwater requirements.

Re: ESA Stormwater Management Plans
Dear John:
The 401 certification for this project was issued on March 13, 1998. Enclosed pleased
find one copy of the final construction drawings for the stormwater basins for your files
and use.
If you have any questions, please give me a call. Unless I hear from you within 10 days,
I will move forward to prepare final bid documents.
I have sent copies of the plans to John Holley for erosion and sediment control approval
as the area to be re-disturbed approaches one acre. I prefer to get his approval even
though it may not be necessary rather than having the question being raised at a later
date.
Thank you for the help that you and Ray Cox gave us while going through the approval
process. I look forward to seeing the construction completed and if you need final as
built plans, please let me know.
Yours truly,
Harlan K. Britt, P. E.

pn April 26, 1989, you and Mr. Aavia Rector met with Ms. Kathy
Trott of my staff west of the Carter Finley Stadium site 10cated
north of Trinity Road and west of Slue Ridge Road outside Raleigh,
Wake County, North Carolina.
The purpose of the meeting Vas to inspect the property for the
presence of wetlands and/or waters of the United States subject to
Department of the Army authority. There were no wetlands noted
adjacent Richland Creek) however, the discharge of excavated or
fill material into the creek, or any one of several tributaries to
the creek, will require Department of the Army authorization.
we would appreciate the opportunity to review the plans as
they become available for a project-specific determination Of
Deparment of the Army permit requirements.
if there are questions, please contact Ms. Trott, Regulatory

Dear Ms. Tripp:
Kimley-Horn and Associates, Inc. is writing this letter on behalf of our client,
Odell and Associates, Inc. to request information from your agency regarding
resources in the vicinity of the proposed access road and culvert crossing of
Richland Creek. The closing will be located on the Centennial Authority
property in west Raleigh. Specifically we would like to know of any records of
threatened or endangered species or protected habitats or wildlife areas known
to occur in the project area, which is shown on the attached USGS map
(Raleigh West, North Carolina quadrangle).
The purpose of the proposed project is to provide ingress and egress connecting
Edward Mill Road Extension and the Entertainment & Sport Arena parking
facilities. Permit coordination has been initiated with representatives from the
N.C. DNER and US Army Corp. of Engineers for the proposed stream crossing.
It is my understanding that your office was contacted during the Environmental
Assessment process in 1993 and your records should reflect your agencies
comments.
Thank you in advance for your assistance. If you have questions regarding this
request, please call me at [phone].
Very truly yours,
KIMLEY-HORN AND ASSOCIATES, INC.

Re: Centennial Authority: Entertainment/Sports Arena
Raleigh, Wake County, North Carolina
Dear Ms. Gledhill-Earley:
Kimley-Horn and Associates, Inc. is writing this letter on behalf of our client,
Odell and Associates, Inc. to request information from your agency that may be
pertinent to the proposed access road and culvert crossing of Richland Creek.
The crossing will be located on the Centennial Authority property in west
Raleigh. Specifically we would like to know of any districts, sites, buildings,
structures, or objects that are significant in American History, architecture,
archeology, engineering, or culture that your agency maintains records of either
through listing or eligibility for listing in the National Register of Historic
Places that may occur in the project area, which is shown on the attached USGS
map (Raleigh West, North Carolina quadrangle).
The purpose of the proposed project is to provide ingress and egress for the
parking facilities at the Entertainment & Sport Arena. Permit coordination has
been initiated with representatives from the N.C. DNER and US Army Corp. of
Engineers for the proposed stream crossing. It is my understanding that your
office was contacted during the Environmental Assessment process in 1993 and
your records should reflect your agencies comments.
Thank you in advance for your assistance. If you have questions regarding this
request, please call me at [phone].
Very truly yours,
Y-HORN ANDD ASSOCIATES, INC.

15.3 / 23.8 = 0.64 of Total DA
EFFICIENCY = 0.64 x 85% = 54.4 % TSS Removal
RECOMENDATIONS:
Use existing Basin #2 with an expanded forebay of 8000 sf. ( 20% of main basin
surface area) on southern end of the existing basin. Re-route all drainage to the
proposed forebay and utilize the existing southern embankment as forebay
embankment.

REQ'D STORAGE DEPTH = 0.77/.32 = 2.4 ft. above normal pool.
THEREFORE: EXISTING STORAGE IS ADEQUATE FOR BASIN # 3
RECOMMENDATIONS :
Basin # 3 is a poor configuration for efficient removal of solids ( W to D ratio).
Recommend the construction of a new embankment to the west and
construction of a new forebay area at the head of the existing basin. The existing
emergency spillway can be continue to serve that purpose with no alteration. The
expansion of this basin will allow for a removal efficiency of 85 % or greater.

Re: Richland Creek Culvert Project E&SA
Dear Ray:
This is to confirm our discussion related to the stormwater management plans
for the new work underway for the Entertainment and Sports Arena. The new
construction consists of the arena structure, adjoining "yard areas," and parking
lots C, D, and G. The total area to be disturbed is approximately 23.80 acres.
As agreed in our January 14th meeting, I am proposing to provide stormwater
management ponds for runoff from lots A, B, G, and one half of the rooftop and
yard area in Basin 2. Basin 3 will provide stormwater management for lots C
and D. The rooftop and yard area on the eastern portion of the arena will not
drain through a stormwater basin. This runoff should be relatively benign
compared to the runoff from parking lots A and B.
Lots A and B are not required to have stormwater management; however, we are
proposing to trade treatment from these two areas in exchange for the eastern
rooftop and yard runoff.
The proposal is to expand Basins 2 and 3 to include forebays with the strategy
being to provide treatment facilities equal to or greater than the treatment
requirements for the new construction.: The-=te I"s c d r i fM for
th' ' " 49`0.77 acr4. Th b T a o > a rrs acrd rs 0 0 s
with additional forebays proposed. The efficiency of Basin 2s,ite1v
54% for TSS. 'lei' ° ? ? than just the area Mer
co4jgp 3 should function at the design criteria or better with
enlargement and forebay construction.

The stormwater analysis for the two basins is attached for your review and
agreement. Upon your review and acceptance, I will proceed to get concurrence
by my client. Subject to my client's agreement we will prepare the appropriate
401 certification application for the road crossing of Richland Creek under the
Nationwide 14 permit.
I anticipate issuance of the 401 certification for the culvert construction with the
provisions for stormwater management and mitigation or payment into the
Wetlands Restoration Fund consistent with DWQ policy.
I sincerely appreciate the time you have given this project during our meetings
and hope this matter can be completed in the very near future.

does not contain suitable habitat for env Federally-listed
endangered or threatened species known to occur in the area.We
believe that the requirements of Section 7 of the Act have been
satisfied. We remind you that obligations under Section 7
consultation must be reconsidered if: (1) new information reveals
impacts of this identified action that may affect listed species or
critical habitat in a manner not previously considered; (2) this
action is subsequently modxf.ioa in a manner that was not consido-rod
in this review; (3) a new' species is listed or critical habitat
determined that may be affected by the identified action.
If the proposed project will be removing p.nes 9" DBH or ,greater, or
30 years of age in ping or pine/hardwood habitat, surveys should be
conducted for active red-cockaded woodpecker cavity trees in
appropriate habitat within a 1/2 mile radius of project boundaries.
IF red-cockaded woodpeckers are observed within the project area or
active cav=ty trees found, the project has the potential to affect
the red-cockaded woodpecker, and you should contact this office for
further information.

Re: Centennial Authority: Entertainment/Sports Arena
Raleigh, Wake County, North Carolina
Dear Mr. Dorney:
Attached is a joint form for Nationwide Permit 14 and Section 401 Certification
for the proposed road crossing of Richland Creek at the Entertainment and
Sports Arena located in west Raleigh. The proposed project will impact
approximately 430 feet of Richland Creek including culvert and riprap channel
protection.
It is our understanding that no wetlands are impacted by the project.
Included with this packet are copies of the site plan, project location map, and a
stormwater management computations. As I understand from our earlier
discussions, I anticipate mitigation for the stream crossing and stormwater
management consistent with the agreement I have with Roy Cox. Copies of
this notification have been sent to the COE.
Thank you for your attention to this project and we look forward to your
earliest possible response. Should there be need for consultation, please give
me a call.
Very truly yours,

Dear Mr. Gamble:

On April 26, 1989, you and Mr. David Rector met with Ms. Kathy
Trott of my staff west of the Carter Finley Stadium site Located
north of Trinity Road and west of Blue Ridge Road outside Raleigh,
Wake County, North Carolina.
The purpose of the meeting was to inspect the property for the
presence of wetlands and/or waters of the United States subject to
Department of the Army authority. There were no wetlands noted
adjacent Richland Creeks however, the discharge of excavated or
fill material into the creek, or any one of several tributaries to
the creek, will require Department of the Army authorization.
we would appreciate the opportunity to review the plans as
they become available for a project-specific determination of
Deparment of the Army permit requirements.
If there are questions, please contact Ms. Trott, Regulatory
Branch, Raleigh Field Office, telephone [phone].
Sincerely,

Dear Ms. Tripp:
Kimley-Horn and Associates, Inc. is writing this letter on behalf of our client,
Odell and Associates, Inc. to request information from your agency regarding
resources in the vicinity of the proposed access road and culvert crossing of
Richland Creek. The closing will be located on the Centennial Authority
property in west Raleigh. Specifically we would like to know of any records of
threatened or endangered species or protected habitats or wildlife areas known
to occur in the project area, which is shown on the attached USGS map
(Raleigh West, North Carolina quadrangle).
The purpose of the proposed project is to provide ingress and egress connecting
Edward Mill Road Extension and the Entertainment & Sport Arena parking
facilities. Permit coordination has been initiated with representatives from the
N.C. DNER and US Army Corp. of Engineers for the proposed stream crossing.
It is my understanding that your office was contacted during the Environmental
Assessment process in 1993 and your records should reflect your agencies
comments.
Thank you in advance for your assistance. If you have questions regarding this
request, please call me at [phone].

SA = .45 ac.
TREATMENT AREA REQ'D. @ SA / DA= 3.07 FOR NEW CONSTRUCTION
AREA REQ'D = 8.69 x 3.07/100= 0.26 ac.
THEREFORE: EXISTING BASIN # 2 IS APPROX. 2 X THE REQ'D.

CHECK FOR RUNOFF CONTROL / DETENTION
RUNOFF VOLUME = 0.05+.009 x (90) = 0.86 inrn
STORAGE = 1" x .86 / 12 (8.69) = 0.62 ac. ft.

15.3 123.8 = 0.64 of Total DA
EFFICIENCY = 0.64 x 85% = 54.4 % TSS Removal
RECOMENDATIONS:
Use existing Basin #2 with an expanded forebay of 8000 sf. ( 20% of main basin
surface area) on southern end of the existing basin. Re-route all drainage to the
proposed forebay and utilize the existing southern embankment as forebay
embankment.

ESTIMATED AVAILABLE STORAGE = 0.32 x 5/2 =.8 ac. ft.
REQ'D STORAGE DEPTH = 0.77/.32 = 2.4 ft. above normal pool.
THEREFORE: EXISTING STORAGE IS ADEQUATE FOR BASIN # 3
RECOMMENDATIONS :
Basin # 3 is a poor configuration for efficient removal of solids ( W to D ratio)
Recommend the construction of a new embankment to the west and
construction of a new forebay area at the head of the existing basin. The existing
emergency spillway can be continue to serve that purpose with no alteration. The
expansion of this basin will allow for a removal efficiency of 85 % or greater.

Dear Mr. Stroud:
Re: Centennial Arena
DWQ # 980100
Wake County
DWQ is in receipt of a letter dated March 31, 1998 requesting a one-month extension
for the payment of funds to the NC Wetlands Restoration Program for stream mitigation
due to recent redesign to reduce the extent of riprap at the upstream side of the culvert.
An additional one-month extension from the original Certification date is hereby granted
for this payment to allow you to investigate the practicality of this design change.
Therefore payment to the Wetland Restoration Program must be made by May 6, 1998 or
the Certification will be revoked.
Please call me at 919-733-1786 if you have any questions.

401 Water Quality Certification Letter
Gentlemen:
On behalf of our Client, The Centennial Authority, we are writing to request a 30-day
extension in time for payment of the contribution to the Wetland Restoration Program for
compensation for the impacts of the Edwards Mill Road Connector Culvert construction
on Richland Creek."
As stated in your 401 Certification Letter of March 6, 1998, The Centennial Authority has
one month from the date of the certification to make the payment. As we discussed with
you during the week of March 23, 1998, we are currently working with the Division of
Land Quality to reach agreement on the reduction of rip-rap channel stabilization in order
to minimize the impact on Richland Creek. Based on meetings with Mr. John Harley on
March 26, 1998, we believe that a reduction in the rip-rap armoring of approximately 60
feet (from 100 feet to 40 feet) on the upstream side of the culvert will be possible. This
would reduce the overall length of stream impact from 440 feet to 380 feet. In order to
provide adequate time to obtain approval of the revised design from the Division of Land
Resources and request and receive a revision to the 401 Certification Letter from your
office, we are requesting a one month extension to the due date for payment to the
Wetland Restoration Program.
We understand from our conversation of March 23, 1998, that you do not anticipate a
problem in granting this extension. By copy of this letter we are advising Mr. Ron Ferrell
of the Wetland Restoration Program of this request. If for some reason you cannot

APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS, WRP AND
NEUSE BUFFER RULES
Steve Stroud; Centennial Authority
1520 Blue Ridge Road; Suite 201
Raleigh NC 27607
Dear Mr. Stroud:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
material in 440 linear feet of waters for the purpose of constructing a road crossing at Centennial Arena
across Richland Creek at Edwards Mill Extension, as you described in your application dated February 3,
1998. After reviewing your application, we have decided that this fill is covered by General Water Quality
Certification Number 3103. This certification allows you to use Nationwide Permit Number 14 when it is
issued by the Corps of Engineers. This approval is also valid for the Neuse River buffer rules (15A NCAC
2B .0233). 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, Coastal Stormwater, Non-
Discharge and Water Supply Watershed regulations. This approval will expire when the accompanying 404
or CAMA 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 except as
modified below. If you change your project, you must notify us and you may be required to send us a new
application. 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 and any additional conditions listed below.
1. An additional condition is that a final written stormwater plan with wet detention basins must be
approved by DWQ before stream impacts occur.
2. A planting plan must be submitted to DWQ for written approval for the riparian buffer along
Richland Creek.
We understand that you have chosen to contribute to the Wetland Restoration Program in order to
compensate for these impacts to wetlands and/or streams. In accordance with 15A NCAC 2R.0500, this
contribution will satisfy our compensatory mitigation requirements under 15A NCAC 2H.0506(h).
According to 15A NCAC 2H .0506(h), 440 feet of restoration will be required. Mr. Ron Ferrell should be
contacted at 919-733-5083 ext. 358 if you have any questions concerning the Wetland Restoration Program.
You have one month from the date of this Certification to make this payment or-this Certification will be
revoked. For accounting purposes, this Certification authorizes the fill of 440 feet of streams, in
030402 river and subbasin and 440 feet stream restoration. Please be aware that the Wetland
Restoration Program (WRP) rules require rounding of acreage amounts to one-quarter acre
increments (15A 2R.0503(b)).
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.

Dear Mr. Stroud:
We are in receipt of your stormwater management plan for the Centennial Arena which
was prepared by Mr. Harlan Britt of Kimley-Horn and Associates and accompanied the
401 Certification application received on 6 February 1998. A technical review of each
pond was conducted, and each was determined to be designed in satisfactory compliance
with the Division of Water Quality's BMP manual. The only remaining issue with
respect to stormwater management is that the signed operation and maintenance
agreements for the subject stormwater management plan which must be received in this
office on March 27, 1998.
This letter hereby provides written approval of the stormwater management plan for the
subject project in accordance with the requirements of the 401 Certification. Please call
me at [phone] if you have any questions.
Sincerely,
0Dorney*

Richland Creek Crossing
Gentlemen:
At the request of the Water Quality Section of the North Carolina Department of
Environment and Natural Resources (NCDENR) and the Raleigh office of the U.S. Army
Corps of Engineers, we have reevaluated the extent of rip-rap protection to be provided
on the inlet and outlet side of the proposed double 8' x 8' box culvert extending 225'
under the proposed Edwards Mill Road Connector. Both of these agencies have
requested that the extent of rip-rap be reduced to the minimum possible length.
The culvert carries an estimated 1,250 CFS during a 50 year storm, resulting in a flow in
each box of 625 CFS. The culvert operates with tail water greater than one half the pipe
diameter and the culverts flow partially full. The attached Partially Full Flow Apron
Sizing Analysis indicates that the length of rip-rap apron on the downstream end of the
culverts can be reduced from its current 100' length to 80'. While there is no requirement
for a rip-rap apron on the upstream side of the box culvert, we are recommending a
reduction in the rip-rap apron length from 100' to 10'. We believe this 10' length will be
adequate to stabilize the channel after culvert installation.
Attached you will find the appropriate calculations for sizing the length of apron on the
downstream end of the box culvert.

Please be advised that we are proceeding with the incorporation of these revised rip-rap
apron lengths into the Construction Documents and request that you advise this office
immediately if this change is inconsistent with your ability to approve the final
installation. If you have any questions in this regard please so advise.
Very truly yours,

8.4 Riprap Aprons
Uses A flat riprap apron can be used to prevent erosion at the transition from a pipe or
8.4,1 box culvert outlet to a natural channel. Protection is provided primarily by having
sufficient length and flare to dissipate energy by expanding the flow. Riprap aprons
are appropriate when the culvert outlet velocity is less than or equal to 10 fps for
pipes s 48 inches in diameter.
Procedure The procedure presented in this section is taken from USDA, SCS (1,975). Two sets
8.4,2 of curves, one for minimum and one for maximum tailwater condition's, are used to
determine the apron size and the median riprap diameter, d60. If tailwater conditions
are known, or if both minimum and maximum conditions may occur, the apron
should be designed to meet criteria for both. Although the design curves are based
on round pipes flowing full, they can be used for partially full pipes and box
culverts. The design procedure consists of the following steps:
1. If possible, determine tailwater conditions for the channel. if tailwater is less
than one=half the discharge flow depth (pipe diameter if flowing full), minimum
tailwater conditions exist and the curves in Figure 8-1 apply. Otherwise,
maximum tailwater conditions exist and the curves in Figure 8-2 should be
used.
2. Determine the correct apron length and median riprap diameter, d5 , using the
appropriate curves from Figure 8-1 and 8-2. If tailwater conditions are
uncertain, find the values for both minimum and maximum conditions and size
the apron as shown in Figure 8-3.
a. For pipes flowing full:
Use the depth. of flow, d, which equals the pipe diameter, in feet, and
design discharge, in cfs, to obtain the apron length, L., and median riprap
diameter, d6,,, from the appropriate curves.
b. For pipes,flowing p
Use the depth 'of flow, d, in feat, and velocity, v, in feet/second. On the
lower portion of the appropriate figure, find the intersection of the d and
v curves, then find the riprap median diameter, d60, from the scale on the
right. From the lower d and v intersection point, move vertically to the
upper curves until intersecting the curve for the correct flow depth, d. Find
the minimum apron length, L„ from the scale on the left.

From Harlan K. Britt, P.E.
Date: December 16, 1997
Subject: Meeting concerning Richland Creek Culvert
Project: Entertainment & Sports Arena
Raleigh, North Carolina
Attending: John Dorney - DWQ
Danny Smith - DWQ
Harlan Britt - Kimley-Horn and Associates, Inc.
Minutes:
1. The meeting discussed the roadway crossing for Richland Creek under the
proposed Nationwide 14 Coverage. A 401 certification is required.
Certification will require mitigation for the stream on a 1'1 basis that is
payable to the Wetland Restoration Fund. Any mitigation required by the
C.O.E. will be handled consistent with C.O.E. decisions.
2. If stormwater is required, it will only be required for the new project and
existing parking lots are not to be included. KHA will discuss with Ray
Cox the stormwater requirements. Arena roof top water on the eastern side
could possibly be traded for lots A & B. It was agreed that roof top water
should not be near the water quality issue that parking lot water presents. It
was agreed to explore trading the roof top water for parking lot water.
3. KHA will work with Ray Cox to reach a recommended treatment level
(percent removal). The 85% removal rate may not be achievable and some (]
level lower but achievable will be sought if it is acceptable to the client. ^ "'?.
4. Message for Ray Cox to call Harlan Britt was left.

Minutes:
1. Mr. Park reviewed the scope of the project including the work covered by the
early parking lot construction project completed in 1994 and the current
construction covering the Arena site, parking lots "C", "D", "G", Edwards Mill
Road Connector, widening of Trinity Road, and a short section of entry road
construction at Gate "B."
2. Mr. Dorney provided Odell with copies of the current NCDEHNR water quality
regulations, a copy of the Best Management Practice Handbook, and the recently
adopted Neuse River Basin Rules.

CONFERENCE MEMORANDUM
Page 2
December 5, 1997
Mr. Park advised that he had been in touch with the U.S. Army Corps of
Engineers and it was the current understanding that the Richland Creek Crossing
fell under Nationwide Permit No. 14 (Road Crossings).
4. Mr. Dorney advised that new rules adopted by NCDEHNR effective February 11,
1997, require State of North Carolina certification. These new rules will require
that the following conditions be met:
a. A one-for-one mitigation of the impacted section of the stream will be
required. Mitigation can take the form of restoration of a like-length of
disturbed creek bed (generally in the same river basin) or through a
donation to the Wetland Restoration Program in the amount of $125.00
per linear foot of disturbed channel.
b. Stormwater treatment of the runoff from the adjacent site will be required
in accordance with the Stormwater Best Management Practices established
by DEHNR.
5. Mr. Dorney advised that he was unsure at the present time whether the stormwater
treatment requirements would apply to the current construction only or would also
incorporate the parking lots and roadways constructed in 1994. Mr. Dorney is to
review this issue and advise Odell of his interpretation.
6. Mr. Park pointed out that the four parking lots and roadways constructed in 1994
added to the parking capacity of Carter-Finley Stadium and had been in use for the
past three years. Furthermore, those lots would have remained in place and
continued to be used as part of the Carter-Finley Stadium Complex in the event
that the Arena had not been constructed. It was therefore Odell's opinion that the
construction of the parking lots and roadways was a completed project separate
from the current Arena construction project.
7. In reviewing the location of the two existing Sediment Basins No. 2 and No. 3 on
the west side of the site, it appears that these basins are in an ideal location for
providing stormwater treatment. Mr. Dorney advised that the surface area
required for the ponds usually range from 1-3% of the surface area of the project.
On this basis, it appears that the ponds may have sufficient area (with some
modification) to be adapted to comply with the Best Management Practices design
criteria.
8. It was agreed that Odell would prepare a preliminary Engineering study to
determine the appropriate pond size for review by Mr. Cocks.

December 5, 1997
9. Mr. Domey also advised that the new Neuse River Basis Rules effective July 26,
1997, also apply to the project. While roadway crossings are permitted under the
Neuse Rules, the same general criteria as described above also are applicable.
10. In addition to mitigation and stormwater treatment, the Neuse Rules require the
maintenance of a 50' vegetation buffer adjacent to Richland Creek. Areas
disturbed as a result of road crossing constructed will need to be replanted using a
planting plan acceptable to DEHNR.
11. The replanting plan should address the restoration of tree coverage within the first
30' from the bank edge with the next 20' returned to its preexisting natural state
which can include grasses.
12. Mr. Domey advised that the appropriate certification letter could be issued by
DEHNR upon approval of an acceptable plan for mitigation and upon agreement
on the size of the stormwater treatment basins for the project.
13. Construction of the box culverts in Richland Creek can resume upon receipt of a
certification letter from DEHNR.
The foregoing conveys our understanding of the items discussed and conclusions reached
during this meeting. We assume this information to be correct, unless notice to the
contrary is brought too attention.

6. Mr. Park pointed out that the four parking lots and roadways constructed in 1994
added to the parking capacity of Carter-Finley Stadium and had been in use for the
past three years. Furthermore, those lots would have remained in place and
continued to be used as part of the Carter-Finley Stadium Complex in the event
that the Arena had not been constructed. It was therefore Odell's opinion that the
construction of the parking lots and roadways was a completed project separate
from the current Arena construction project.
7. In reviewing the location of the two existing Sediment Basins No. 2 and No. 3 on
the west side of the site, it appears that these basins are in an ideal location for
providing stormwater treatment. Mr. Dorney advised that the surface area
required for the ponds usually range from 1-3% of the surface area of the project.
On this basis, it appears that the ponds may have sufficient area (with some
modification) to be adapted to comply with the Best Management Practices design
criteria.
8. It was agreed that Odell would prepare a preliminary Engineering study to
determine the appropriate pond size for review by Mr. Cocks.

9. Mr. Dorney also advised that the new Neuse River Basis Rules effective July 26,
1997, also apply to the project. While roadway crossings are permitted under the
Neuse Rules, the same general criteria as described above also are applicable.
10. In addition to mitigation and stormwater treatment, the Neuse Rules require the
maintenance of a 50' vegetation buffer adjacent to Richland Creek. Areas
disturbed as a result of road crossing constructed will need to be replanted using a
planting plan acceptable to DEHNR.
11. The replanting plan should address the restoration of tree coverage within the first
30' from the bank edge with the next 20' returned to its preexisting natural state
which can include grasses.
12. Mr. Dorney advised that the appropriate certification letter could be issued by
DEHNR upon approval of an acceptable plan for mitigation and upon agreement
on the size of the stormwater treatment basins for the project.
13. Construction of the box culverts in Richland Creek can resume upon receipt of a
certification letter from DEHNR.
The foregoing conveys our understanding of the items discussed and conclusions reached
during this meeting. We assume this information to be correct, unless notice to the
contrary is brought to o attention.

Gentlemen:
We are in receipt of your letter of November 9, 1999, concerning approval of the
Landscape Plan for the Richland Creek area on subject project. In that letter you note th
tree planting must also be done within a 30 foot distance of each side of the creek
between Trinity Road and Edwards Mill Connector Road except in the maintenance
corridor of the existing sewer line and right of way of Trinity Road.
Please be advised that the limits of construction for the Entertainment and Sports Arena
did not encompass the area of Richland Creek between Trinity Road and the southern
limits of the rip-ran apron on the south end of the connector road. The sanitary sewer
relocation and the stockpile of material south of the connector road impacted areas east of
the sanitary sewer easement only. Work on Trinity Road terminated short of Richland
Creek (at the end of the sidewalk along Trinity Road) and was restricted to the Trinity
Road right of way. To the best of our knowledge and based on our review of field
conditions, and a field check by the General Contractor, we do not believe that there was
any damage to existing plantings bounded by the Trinity Road right-of-way, the southern
limits of the rip-rap apron, the creek, and the sanitary sewer right-of-way on the east side
of the creek or along any portion of the west side of the creek between Trinity Road and
the rip-rap apron. We believe that any damage that may have occurred in these areas
were the result of the construction of Edward's Mill Road and the widening of Trinity

We therefore request that you reconsider the additional requirements stipulated in your
November 9, 1999, approval letter and on the basis of the above, approve the October 8th
landscape planting plan as originally submitted. Should you have any questions
regarding the above or require any additional information please so advise.

Gentlemen::
u i?rf a

Enclosed are two copies of a proposed Landscape Plan for the restorative planting along
the section of Richland Creek affected by the construction of Edwards Mill Road
connector at the Entertainment and Sports Arena project site. This drawing is submitted
for your review and approval.
Please note that there are other plantings indicated on this drawing not associated with the
Richland Creek Restoration. We are asking for your review of the Richland Creek
Restoration Plantings only.
Please be advised that we also anticipate construction on the storm water treatment basins
to begin this fall as soon as all of the tributary portions of the site are stabilized and the
existing sediment basins can be planed.
We would like to proceed with the installation of these plantings as soon as plant material
is available and the deciduous trees are dormant. We would therefore appreciate
receiving your approval of this planting plan as soon as possible. Should you have any
questions or require additional information, please so advise.

Please find the attached final plans for the stormwater management ponds at the
ESA. The plans support the engineer's claims in regard to the surface areas. The surface
area of Basin 3 is 5% undersized and the temporary pool volume is 8% undersized to
treat the drainage area. However, considering the difficult history of this project, I
recommend that the plans dated November 29, 1998, for Basin 2 be approved based on
the memo from Ray Cox dated February 19, 1998, and that the plans dated October 5,
1998, for Basin 3 be approved.
