USACE - In accordance with the Final Notice off Issuance and Modification of Nationwide
Permits, published in the Federal Register on Mar h 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the quatic environment are minimal. Factors
including size and type of proposed impact and nction and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation tha may be appropriate and practicable include,
but are not limited to: reducing the size of the pr ject; establishing and maintaining wetland
and/or upland vegetated buffers to protect open wa ers 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 watersh d.

Proj ct Summary
he project site is an existing drainage ditch that runs through the University property. The ditch
arries runoff from approximately 30 acres: of surrounding residential, undeveloped, and University
t nd. The proposed area is adjacent to a large parking lot which drains completely into the site. The
ite also collects runoff from surrounding buildings and lawn areas. The design proposal involves
idening the bottom surface of the ditch, installing a detention outlet device, and planting wetland
plants. The design will increase stormwater storage while not limiting drainage capacity for large
events. Wetland plants will improve th'e aesthetics of the area and provide an educational
pportunity for the University. The wetland should not require any additional maintenance effort
om the University.

h% E Ilizabeth ;City State University Stormwater Wetland Project involves the retrofit of an existing
?iteh to a stormwater wetland. The site has; been designed to improve stormwater storage and
? reatm nt, while meeting University drainage needs. The site is located at Elizabeth City State
Unive sity in Pasquotank County, North Carolina.
1.2 G als and Objectives
The p 'mary goals of the project are:
1) Retrofit an existing ditch to improve stormwater detention and treatment.
2)I Demonstrate economical and aesthetic alternatives to traditional drainage.
3 Provide educational opportunity and promote further work in the watershed.
1.3 P' oject Background
This roject was initiated in the Spring of 2004 by the NC Ecosystem Enhancement Program (EEP).
The project is partly related to the development of local watershed plans, the need for water quality
impro ements, and the needs for education and demonstration of water quality projects in the area. The
initial stages of the project involved the evaluation of several potential sites in the Camden and
Pasq tank County areas. The eventual projectsite was chosen due to its location, the opportunity for
ecbn ical implementation, and the potential for University partnership. The involvement and
I coop ration of Elizabeth City State University has been and will be critical to the continued success of
the p ject.
An a reement was reached between the EEP and the University in the spring of 2004 and -design
activities began on June 1. Analysis and design for the project was completed in early July and this
docu ent was prepared. This report describes the analysis and design for the project and includes
map drawings, and construction information. It is intended that this report be used as the construction
man al for the project completion.

DESIGN
Survey
raphic survey of the site was prepared using a laser level. This approach was taken to facilitate
iency of the survey effort. The survey is not tied to any published vertical or horizontal datum.
benchmark is the top of the existing outlet culvert. The elevation of this point was assumed at
Several other reference stakes and benchmark points were set up for construction purposes.
n data was acquired, for all pipes in the area, roads, curbs, inlet structures, and a total of 21
?tions. In addition, trees, pipe inverts, fences, and other points of interest were located using a
k gps unit. A map was generated using the data and available aerial photography. Contour
:ion was generated for the project area and raw elevation data were used in the design and
phases.
2.2 W tershed Analysis
The e tremely flat topography and complex underground drainage systems in the area required an
innov tive approach for watershed analysis. The contributing watershed for this site was determined
using available lidar data, aerial photography, a watershed reconnaissance field visit, and gps
equip ent. The watershed was found to be approximately 30 acres and consist of a mixture of low
densi residential neighborhoods, forested and undeveloped areas, and developed University property.
h
ed hydrologic models were developed using WinTR-55 and HEC-HMS software. The models
Wate te
were A to determine runoff volumes and peak flows for storms with 1 and 2-yr return intervals. The
runo l volume was also predicted for smaller storms of 1 and 1.5 inches of rainfall.
2.3 tletDevice Design
The urrent outlet control of the ditch is a 2 ftj diameter high density polyethylene pipe (HDPE). The
retro it of this culvert will be necessary to achieve the appropriate hydrologic conditions to support the
desir d vegetation, control stormwater flows, 'and ensure high flow drainage capacity. The primary
meth-?d for creating a functioning wetland with additional storage for treating stormwater is to reduce
the p ak outflow rate at non-flood stages and allow waters at lower stages to drawdown slowly. This
invo ed designing an outlet structure that Would raise the normal water level slightly, allow for
sto water storage up to flooding elevations, and not limit high flow drainage capacities.
Desf of this device first omeant completing an analysis of the current drainage and outlet capacities.
This step involved the use of HY-8 culvert analysis software. This software allowed the determination
of c lvert capacities at various water surface elevations, factoring in the current tailwater conditions at
the ite. The next step is to size the retrofitted outlet device so that high flow capacities can be
mai tained. For this purpose, the lowest elevation that would cause backup of water into the parking
lot as chosen. When the water surface reaches this level, the outlet riser diameter and top elevation
was adjusted until the high flow drainage requirements could be met. A riser diameter of 4' was found
to p oxide the necessary capacity.

.5 Dr' wdown Design
dxa , down device has been designed for the proposed outlet structure. The device is designed to
?aint n storage volume below the top of the owlet weir and drawdown to normal levels over a period
bf at 1 ast 24 hours. The actual drawdown period can vary depending on the storage space available,
size o? the drawdown device; and the type of wetland and vegetation specified. The device consists of
a length of PVC pipe that will be installed in thei outlet structure at a specified elevation. The pipe will
have 90 degree elbow turned downward at the end which will prevent the orifice from getting
clogge with trash and debris. Analysis determined that a 2 inch diameter pipe would allow the
wetla water surface to draw down from the top of the weir to normal level in 1.3 days. A smaller
device is not practical and a larger storage space/longer drawdown periods are not possible without
causin adverse flooding of the nearby parking lot.

All ediment and erosion control should be sett up prior to any other work occurring at the site. Three
sedi ent baffles shall be installed to control erosion during this project. The baffles consist of a jute
ma ing hung on steel posts at a 6 ft spacing. The baffles shall be placed near the outlet culvert. They
sho Id be placed 6 ft apart and extend across the entirety of the channel and up the bank.

3.5 Ouilet Installation
The owlet structure shall be constructed of corrugated aluminum piping and will be delivered with
pprop iate flashboard risers. The structure shall be installed by sliding the outlet pipe inside the
xisti culvert. The existing, culvert will need to be cleaned of all sediment and debris to facilitate the
nstall tion. An appropriate area shall be excavated around the culvert also to complete the proper
[?nstalh tion. Concrete or grout will be poured to ensure the seal and connection of the two pipes.
Backfi 1 the area with soil after installation is complete and blend the grade into the existing slope. The
slope hould be reseeded as necessary.
3.6 G ading
The u stream end of the project site shall be expanded and widened. Grading will begin at the staked
outer oundary of the project and follow a 4:1 (H:V) slope to the desired wetland bottom elevation.
Suital? a soils from the excavation shall be spread throughout the wetland to achieve the desired bottom
elevat on or as directed by tl e Project Engineer. Sideslopes throughout the site shall be widened to the
extent possible and tilled. Suitable soil should alsso be used to amend sideslopes by mixing/tilling.
Durin the grading, a total of three small trees will need to be transplanted. Complete the transplanting
by ex avating the entire tree with as much root ball as possible. Then replant the tree at the project
boundary.
3.7 P' rking Lot Outfall Rotrofit
Rem e the parking lot outfall as indicated. Make a clean cut and repair as necessary. The retrofit will
invol e a small amount of excavation and tilling of the area. Excavate to create two cascading pools, at
the di ection of the Project Manager, below the curb cut. Seed the pool areas and protect with Class B
iprap lunderlain with Excelsior type or equivalent erosion control matting.
