Please find the attached plans for the extended wet detention wetland and vegetative
swale/berm structures for treating stormwater at the Centennial Middle School. It is my
understanding that, eventually, the berm structures will be replaced with an extended wet
detention pond or wetland after the watershed draining to the berms becomes developed.
The plans dated March 10, 2000 appear to be adequate except for the planting of Elodea
canadensis. Steve Kroeger recommended that the applicant plant Valisneria americana
instead. As such, I recommend that the plans be approved with the above caveat.

MAINTENANCE AND OPERATIONAL PROCEDURES
CENTENNIAL CAMPUS EXTENDED DETENTION WETLAND #1
GENERAL OVERVIEW:
The subject facility is located just off the southeast corner of the lot containing Centennial
Campus Middle School on the east side of Main Campus Drive. The facility consists of the
following basic components: (1.) an earthen embankment (top elevation 350 ft. MSL)
approximately 300 feet in length, (2.) an unlined, grassed emergency spillway off the southern
end of the embankment approximately 27 feet wide, (3.) a principal spillway system with
approximately 47 linear feet of 36-inch RCP and a formed concrete riser inlet structure, and (4.)
a reservoir area approximately 13,652 square feet in size at normal pool elevation 346 ft. MSL
partitioned into three distinct areas: (a.) an aftbay area, approximately 2,411 square feet in
surface area at elevation 346 ft. MSL, directly adjacent to the principal spillway riser structure
which is by design devoid of vegetation, (b.) a wetland planting area, approximately 9,552 square
feet in surface area at elevation 346 ft. MSL, which contains wetlands vegetation, and (c.) a
riprap lined forebay area, approximately 1,689 square feet in surface area at elevation 346 ft.
MSL, which functions as an entry/dissipation pool for the facility.
FACILITY FUNCTION:
This basic design function of the facility is to detain runoff from a one inch rainfall within the
watershed draining the principal spillway system for an extended period of time (76 hours)
in order to allow suspended solids and pollutants carried by the runoff to settle out and be
removed by the complex micro topography established as a result of specialized wetlands
planting within the reservoir area.
The riser structure functions as an uncontrolled, multi-level reservoir inlet/outflow structure. The
2-inch orifice tube with invert at 346 ft. MSL restricts outflow from the one inch rainfall which
fills the reservoir to elevation 347.75 ft. MSL. In order to protect the embankment from erosive
overflow, reservoir waters are allowed to freely flow over the walls of the riser structure at
elevation 347.75 ft. MSL for increased outflow rate and outflow rate is further increased by
allowing reservoir waters which rise to elevation 348.75 ft. MSL to also flow through the
emergency spillway.
MAINTENANCE PROCEDURES:
Maintenance of Earthen Embankment
A. The earthen embankment shall at all times maintain a thick, healthy grass cover
which is free of brush. This type of cover, if properly maintained, will prevent
erosion of the embankment and provide an easy surface for inspection.

Maintenance and Operational Procedures
Centennial Campus Extended Detention Wetlands #1
B. Grass mowing, brush cutting, and removal of weed vegetation will be necessary to
the proper maintenance of the embankment. The embankment slopes and
emergency spillway area shall be mowed when the grass exceeds twelve inches
(12") in height. Acceptable methods include use of mowers, power brush cutters
and weed whips.
C. Trees and other unwanted woody vegetation shall not be allowed to grow on the
earthen embankment. Any vegetation which inhibits proper operation of the facility
shall be removed.
D. All erosion gullies which form shall be repaired.
E. The embankment, including areas at least twenty feet beyond the downstream toe of
the embankment, shall be inspected for excessive seepage annually. This inspection
can coincide with mowing and other maintenance activities. Seepage may vary
from a soft, wet area to flowing water.
F. During the regular annual inspection, the entire embankment shall also be inspected
for cracks. There are two major types of potential, serious cracks which may lead to
embankment failure and total loss of reservoir:
Traverse Cracks: Traverse cracks appear crossing perpendicular to the
embankment top centerline and indicate differential settlement within the
embankment or its foundation. Any area of the embankment experiencing
excessive settlement (greater than four inches (4") between the two sides of the
crack) must have the settlement source identified and repaired; and the
embankment must be restored to original elevation.
Longitudinal Cracks: Longitudinal cracks run parallel to the centerline of the
embankment and may indicate early signs of a slope or "slide" failure. Arch
shaped cracks are an indication that a localized slope failure is taking place and
progressing. Once slope failures take place and complete their movement, a
vertical soil wall may be left which may slough off an allow severe embankment
erosion into the reservoir area.
In the event excessive seepage or significant cracks are observed during periodic
inspections or at any time, repair plans should be prepared and carried out
immediately.

2. Maintenance of Emergency Spillway Area:
A. The emergency spillway area should be kept free of debris and mowed as the
embankment.
B. All erosion gullies which form between maintenance operations shall be backfilled
with topsoil material, re-seeded and mulched properly until new vegetation is
established.
C. Trees and other unwanted woody vegetation shall not be allowed to grow in the
emergency spillway area. Any vegetation which inhibits flow through the spillway
area shall be removed.
Maintenance of Principal Spillway System:
A. The two inch (2") orifice tube and the riser structure overflow walls shall be kept
free of debris. The two inch orifice tube shall be rodded annually and anytime the
reservoir level remains above elevation 346 MSL during periods when no rainfall is
experienced at the site.
B. The six inch (6") bottom drain valve shall be exercised during the regular annual
inspection and the bottom drain inlet shall be kept free of mud and debris, always
allowing free flow through the inlet.
C. All concrete portions of the system shall be inspected during the regular annual
inspection for signs of cracking or deteriorization. Minor needed repairs shall be
made immediately upon notice of damage. Also during the regular annual
inspection, the interior of the 36 inch RCP conduit shall be inspected for signs of
damage, leakage and/or misalignment. Should any such signs occur or significant
deterioration of other spillway components be noticed, repair plans should be
prepared and carried out immediately. The spillway conduit shall be kept clear of
debris and shall not be allowed to serve as permanent shelter for animals which may
introduce such debris.
4. Maintenance of Wetland Planting Area of Reservoir:
A. The wetland planting area of the reservoir shall be kept clear of debris and shall be
kept clear of accumulating sediments by removal of such sediments if necessary.
Page 3
Maintenance and Operational Procedures
Centennial Campus Extended Detention Wetlands #1
B. Once the initial planting of wetlands plants have become established (after the one
year contractor's warranty), the wetland planting area of the reservoir shall be
allowed to experience natural wetlands plant replacement and proliferation. Should
vegetation which prevents the natural proliferation of plants indigenous to wetland
environments become established in the reservoir area, such plants will be carefully
removed so as not to harm adjacent wetlands plants.
Maintenance of Forebay Area:
A. Accumulated sediments within the forebay area shall be removed as needed.
B. The two 12 inch RCP pipes which assist in drainage of the forebay shall be
inspected just as concrete components of the principal spillway system and on the
same schedule.
6. Inspection Documentation:
Records shall be kept for all inspections, observed conditions, and maintenance activities.
Such records shall contain the following headings as a minimum:
Person Performing the Inspection or Maintenance Procedure:
Date of Inspection or Maintenance Procedure:
Inspection Observations and Notes:

Raleigh, NC 27695-7201
Dear Mr. Worsley:
You have our approval, in accordance with the attached conditions and those listed below, to place fill material in 148 linear
feet of streams for the purpose of constructing a road at Centennial Campus Middle School at NCSU Centennial Campus, as you
described in your application dated February 11, 2000. After reviewing your application, we have decided that this fill is covered
by General Water Quality Certification Number 3108. This certification allows you to use Nationwide Permit Number 26 when
the Corps of Engineers issues it. This approval is also valid for the Neuse River buffer rules (15A NCAC 2B .033). 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 Stonmwater, 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 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) (6) and (7). This approval shall expire when the corresponding Nationwide Permit
expires or as otherwise provided in the General Certification. For this approval to be valid, you must follow the conditions listed
in the attached certification and any additional conditions listed below.
1. A additional condition is that a final, written stormwater management for stormwater runoff using a constructed wetland as
outlined in the September 27, 1999 plan submitted to DWQ from this project shall be approved by this Office before the impacts
specified in this Certification occur. The stormwater management plan must include plans and specifications for stormwater
management facilities designed to remove 85% TSS according to the most recent version of the NC DENR Stormwater Best
Management Practices Manual.
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

Re: Nationwide Permit/401 Water Quality Certification Request
Centennial Campus Magnet Middle School
Corps Action ID 199820433/ DWQ ID 980033 tQ??
Dear Mr. Tugwell & Mr. Dorney:
The purpose of this letter is to request Nationwide Permit (NWP) 26 for the project
'known as Centennial Campus Magnet Middle School. The project is located on NCSU
Centennial Campus (Wake County). The site is shown on the attached USGS
topographic quadrangle vicinity map and plans.
NWPs 12, 14, and 33 were previously issued for this project on March 4, 1998. Project
plans were revised and a new authorization was issued for the use of NWP 12 on
January 29, 1999. The new NWP 12 authorization replaced the previous one and
nullified the authorizations for NWPs 14 and 33. Construction impacts covered under
NWP 12 have been completed.
Authorization to use NWP 26 is requested to cover impacts associated with construction
of the permanent access road previously authorized but later withdrawn. Based on our
conversations, we understand this impact must be covered under NWP 26 because NWP
14 has already been utilized elsewhere on the site. Approximately 148 linear feet of
unimportant/insignificant channel will be impacted by the permanent access road. This
impact includes the culvert plus the energy dissipater located at the downstream end of
the culvert.
As a condition of the 401 Water Quality Certification for the aforementioned
authorizations, NCDENR - DWQ requested the applicant incorporate a wet detention
pond into the facility's stormwater management plan. Authorization to use NWP 26 for
construction of this pond is also requested. Construction of the pond will impact
approximately 177 feet of unimportant/insignificant intermittent channel by
excavation/flooding. Locating the pond upstream of an existing culvert minimized

impacts to the channel. These impacts were calculated based on plans dated
September 13, 1999 and approved by NCDENR - DWQ in a letter to the applicant dated
October 8, 1999 (Copy attached). Please note that McEvoy Engineering designed the
pond and may be contacted directly for supporting calculations, if required (Telephone #
919/783-5303).
Site plan sheets (L & M) showing the additional impacts to jurisdictional areas are
attached. Impacts to wetlands have been avoided. Additional project impacts to waters
of the U. S. total approximately 0.0275 acre. The proposed wet detention pond will create
approximately 0.35 acre of jurisdictional area. It is also important to note that the pond
impacts are necessitated by the desire to improve/protect water quality and a portion of
the impacts was previously authorized without mitigation (i.e. the access road). Based on
these considerations, the low quality of the channel impacted, and because the total
jurisdictional area will be increased by the project as proposed, we do not believe any
mitigation beyond construction of the pond should be required.
Current DWQ criteria for impacts to areas subject to Neuse River Riparian Buffer Rules
do not require mitigation for impacts due to ponds if the buffer is re-established around
the pond or for road crossings that impact equal to or less than 150 linear feet or 1/3 of an
acre of riparian buffer. The access road crossing as proposed does not exceed either
threshold for mitigation. The applicant plans to maintain a 50-foot buffer around the
entire pond area with the exception of the area adjacent to the permanent access road. As
the pond itself is designed to treat stormwater runoff from the facility, Neuse Buffer
mitigation should also not be required.
Please contact us if you have any questions or would like to schedule a site visit, if
required.
Sincerely,
Kevin C. Martin
President
