INTRODUCTION
Oriental, North Carolina is a Coastal Village
located on the Neuse River in Pamlico County. The
Town is home port for a commercial fishing fleet;
pleasure boats and transient vessels. The town is
located at the confluence of nine creeks: Camp
Creek, Smith Creek, Morris Creek, Green Creek,
Racoon Creek, Pierce Creek, Kershaw Creek,
Whitaker Creek East Branch, and Whitaker Creek,
West Branch. The Town is 660 acres in size which
consists of 380 acres of land and 140 acres in
creeks. One hundred fourty (140) acres in the
Neuse River (660 feet in front of the Town). The
Town is endowed with approximately 13,400 acre -
inches (280 acres x 48" Depth) of Public Trust
Waters; about 8 miles of waterfront; there are
about 13 miles of paved streets in Town (about
32.5 acres); there are about 500 houses (allowing
house equivelants for large buildings) amounting
to about 17.5 acres of Roof Tops.
The town occupies over 2 miles of shoreline
(from Pierce to Smith Creek inclusive) on the
widest river in the United States - the Neuse
River which is about 3 miles wide at this point.
This comprises over six squares miles - nearly
4000 acres of Public Trust Waters in the
Page 1

estuarine system. This is 720,000 acre -inches of
Brackish water. The Neuse River is non -tidal -
being influenced only by Wind Tides. Southwest
winds produce low tides in direct relation to
wind velocity. Northeast winds produce high tides
in direct relation to wind velocity. "Normal
Tide" is attained with no wind and no rain for a
day or two and is then about 0.5 feet above Sea
Level (NGVD).
Salinity of the River and Pamlico Sound varies
from near fresh at New Bern (specific gravity of
about 1.0050) to Minnesott`s sp.gr of 1.0136 to
Oriental's sp.gr of 1.0204 to Ocean Water at the
inlets of the Sound (sp.gr. 1.0256). New Bern
water is about 95% fresh water and 5% ocean water.
Minnesott is 50% fresh water and 50% ocean water.
Oriental is about 75% ocean water and 25% fresh
water.
The Neuse River is designated "Coastal Fishing
Waters". "Inland Fishing Waters" begins at
designated points near the mouth of the creeks;
however, some salt water is found in the creek
system.
Oriental's economy has always been at the
bottom of the States economic barrell. During
the period when the Saw Mill was in operation,

it produced jobs and there was some prosperity.
With the decline of farming, Oriental is being
forced more and more to depend on its waterways
for the future. The banks of these waters must
provide access for the commercial fishing industry
as well as the sport fisherman and vacationers.
All precautions must be taken to preserve the
marine life and the water quality so that people
will be able to use and enjoy this natural
resource.

OBJECTIVES OF A DRAINAGE STUDY
FOR
THE TOWN OF ORIENTAL, NORTH CAROLINA
This study of Storm Water Runoff for the Town of
Oriental, North Carolina was made with the objec-
tive of enhancing the Water Quality of the Pamlico
Watershed.
Phases of the study were:
1. Conduct topographic survey of the town; locate
existing drainage facilities and evaluate their
effectiveness; locate potential choices for
alternative outfall.
��
��r 2. Divide town into Drainage areas according to
receiving waterbodies.
3. Determine drainage routes and receiving water -
bodies which will lead to better water quality
and investigate possible features which can be
located in route to upgrade the discharge.
4. Provide maps of the town drawn to a scale
sufficiently large to identify features of
topography, existing facilities, and proposed
plan of drainage.
5. Study alternatives for existing drainage with
the objective of improving and enhancing the
receiving waterbody.
`~~ 6. Study ordinances, land use and future growth

possibilities to identify runoff problems in
future.
7. Employ, contract or otherwise provide labor and
equipment to construct and evaluate studies in
specific areas of concern. Approval will be
obtained in conference prior to construction.
8. Provide cost estimates for the construction and
implementation of new plan.

DRAINAGE AREAS
DRAINAGE AREA A: This area drains directly to
Neuse River. It is character-
ized primarily by grassed
street -side ditches or swales
which channel storm water to
several collection points where
a culvert carries the water to
Neuse River.
DRAINAGE AREA B: The Lagoon Canal system is the
primary drainage facility for
the Town. It is a major
through town canal which
empties into three lagoons and
from the lagoons into the
harbor (Racoon Creek). Grassed
street -side ditches or swales
carry storm -water runoff to
this drainage system.
DRAINAGE AREA C: The Camp Creek Basin drains
water from the northwestern
side of Broad Street (NC High-
way 55) and the Midyette St.
area for the length of the
town. Storm -water gets there
any way it can, sometimes by

0
s
the most devious routes. Most-
ly, however, the route is open
ditch and curb and gutter and
some long culverts
DRAINAGE AREA D: The Beach Canal or the John
Bond Canal drains an area from
NC Highway 55 to the beach on
Neuse River. The canal is
creek -like and contains water
all the time. The mouth at the
beach shoals over and creates a
dam of sand which causes the
canal to hold storm -water until
enough force is generated to
wash an outlet. Expansive
grassed areas are on both sides
of the canal and water from the
street system flows across this
grassed area.
DRAINAGE AREA E: Street -side ditches direct
storm -water to the canals off
Whitaker Creek. Again, these
ditches are grassed swales
which keep water velocity at
a very minimum.
Page 2

0
DRAINAGE AREA F: This area, we call backyard
drainage. Home sites in this
area own to the creek and water
is directed along lot lines in
grassy swales to the creek.
Each lot generally provides its
own drainage and each owner
tries to minimize any erosion
or bad effects of storm water.

DRAINAGE PROMEM AREAS
The town is situated in an area that is
essentially flat topography with minimal grades
available for storm -water drainage. Relatively
minor errors in culvert installation, improperly
dug ditches, and lack of regular cleanout and
maintenance of existing facilities frequently
causes ponding in many areas throughout the town.
This standing water and resulting soggy conditions
in many yards breeds mosquitoes and encourages
other pests and constitutes a significant health
��
��� problem to the community.
Through a combination of topographic field
studies, inventory and inspection of existing
facilities, site inspections during and after rain-
storms, discussions with town officials, and con-
versations with residents, many areas needing im-
provement in drainage quality have been identified
throughout the town. Numerous small problems were
noted which could be alleviated in a few minutes
with a sharp shovel, these are not dealt with here
in detail. The more serious problems and a pro-
posed solution are discussed in the following
pages.
��

MAJOR PROBLEM AREAS
A. RA{AUV ROAD - Along entire length from NC 55 to
Neuse Drive. See Photos 1-10
Ponding in the roadside ditches is caused primarily
by blockage of driveway culverts due to siltation
and the ditches being dug too deep. The problem is
aggravated on the south end by lack of an adequate
outlet and on the north by vegetation and debris in
the small outlet ditch.
PROPOSED SOLUTION:
Provide regular maintenance of culverts and ditches,
construct an additional outlet near Ragan Road at
Link Lane, cleanout and maintain outlet ditch behind
Mac's Mini Mart.
B. MIDYETTE STREET - From North Street to NC 55
See Photos 53-64
Ponding in the street and in yards along the street.
At present runoff is to the street and west along
the street from the break point to the highway ditch
at NC 55 or east to the ditch near North Street
which drains to the canal off the head of Camp
Creek. Residents park their cars in yards adjacent
to the street or on soil driveways. Few driveway
culverts and no roadside ditch exists.
Construct culvert crossing street and ditch to
Page 1

Camp Creek Canal near midpoint of area (as easements can
be obtained.). Construct curb and gutter along street.
C. FIRST AVENUE - From Mildred Street to beach canal
See photos 48-52
Ponding in ditches
Present drainage routes for this area include two
ditch and pipe networks along Mildred Street and
High Street emptying directly into Neuse River. The
pipe on both routes is old, deteriorated eight inch
terra cotta. The pipe along Mildred Street is
broken and blocked in several places and poorly
��
��� maintained driveway culverts further restrict the
flow. The pipe along High Street is open and
draining well.
PhUPOEED SOLUTION:
Install pipe under Mildres St. and High St. and
grade ditch to route water along the north side of
First Avenue through the existing pipe under Vande-
mere St. into the beach canal. This will relieve the
the burden on inadequate structures and re-route the
runoff to an environmentally more advantageous dis-
charge point.

culverts is evident, but the situation is primarily
a result of the ditches between the driveways being
too deep.
PROPOSED SOLUTION:
Grade ditches properly to allow flow through
culverts.
E. MAJOR DITCH SYSTEMS- Needing clean -out
a. Lagoon Canal from NC55 to Church St. at School
House Apartments. Overgrown, trash build-up.
b. Ditch from Mildred Street along west side of
Fulcher Subdivision to Lagoon Canal. Overgrown,
trash build-up, vegetation impediment.
C. Ditch network from NC 55 crossing Gilgo Road at
the Woman's Club Building and along the north
side of Starboard Circle. Siltation, overgrown,
partially blocked pipe at Gilgo Road
d. Ditch along Midyette Street and Charlie Lewis
Avenue by the old saw mill. Siltation, trash
build-up, vegetation impediment.
e. Beach Canal to Village Restaurant and Village
Condos. Vegetation impediment, trash build-up,
overgrown in places.
f. Mildred Street to Beach Canal. Vegetation
impediment, trash build-up.

F. MILDRED STREET AT M]IyYETTE APARTMENTS
See Photo #42
Ponding in street and east edge of street. Pave-
ment is sunken and very deteriorated. Surface
drainage of east edge of street is obstructed by
concrete driveways and poor grading.
PROPOSED SOLUTION:
Repave street through affected area and grade
shoulder and yard to channel runoff.
G. M]]=IUR]D STREET AT SOUTH AVENUE
Ponding in ditch on east side. Pipe to river is
broken and blocked.

CONCLUSIONS
The drainage problems of Oriental are typical
of flat land and drainage. Water must be routed to
ditches and ultimately to the creeks and rivers.
Ponding is caused by sometimes minor siltation and
blockage at critical points.
Oriental is interlaced with sea level out -
falls and drainways to them have been well estab-
lished for many years. The engineering aspects for
draining the town are relatively simple with spot
problems involving the release of shallow water and
the maintenance of drainways.
The enhancement of storm water runoff is a
natural phenomenom in Oriental. The two primary
drainage canals consist of sea level entrapments
with controlled and restricted out flow into the
estuarine system. The Lagoon Canal and three
lagoons flow into the harbor (Racoon Creek) through
a culvert at Hodges Street which limits the flow.
The Beach Canal (John Bond canal) is a long creek -
like canal which flows through a culvert and most
times is restricted by a sand bar.
"The Loop" around the "old" part of town has
nearly all the curb and gutter in town. Two out-
lets flow to Neuse River and the rest of the water

9
0
is "processed" by the lagoon system.
Storm water which flows to the creeks and
river is enhanced by near flat grassy swales and
gutters.
Oriental has fifty (50) acres of impervious
surfaces which is 13% of the land area of town.
Future development is not likely to increase this
percentage since most subdivision land is in 1/3
to 1/2 acre lots. This ratio is a 2,000 square
foot building on 15,000 square feet of land.
An active maintenance program to keep the
storm water drained from the town along the exist-
ing waterways will enhance the quality of the town
and improve the quality of the run-off.
