Town of Kure Beach
OCEAN OUTFALLS STUDY
Spring 2001
EXECUTIVE SUMMARY:
The Town of Kure Beach North Carolina is located in New Hanover County adjacent to
historic Fort Fisher State Park in Southeastern North Carolina. The Town is known for its
beaches that drive the predominant tourism economy of the Kure Beach. Of particular
concern to the Mayor and Town Council are eighteen (18) ocean outfall storm water
drains in their Town that empty storm water into the Atlantic Ocean along the beachfront.
For health, safety, and economics, the Town has determined that these outfalls should be
removed and storm water diverted to a site where it can be properly treated. To
accomplish this, the Town established the Town of Kure Beach Storm Water Task Force.
The Desired Outcome of the Task Force was to thoughtfully study the issue and prepare a
viable plan of action for eliminating the storm drains.
The Board purposefully crafted the committee to include representatives of the various
Federal and North Carolina Agencies who either had regulatory oversight, professional
interest, or ownership in some aspect of the problem. These officials met with
representatives of the Kure Beach Governing Board and Town Staff in meetings
facilitated by the Cape Fear Council of Governments (CFCOG), who was sub -contracted
by the Town to administer a CAMA Planning Grant to conduct the study. (Appendix _list
the Task Force Membership).
To achieve the desired outcome the study followed a logical and analytical approach:
❑ Define the Problem
❑ Determine Ownership of the Problem
❑ List and Prioritize Possible Solutions
❑ Identify Obstacles to Success and How to Overcome Them
❑ Identify Funding Sources
❑ Determine Next Steps
❑ Establish an Action Plan
The Task Force met three times between March and June in open session at the Kure
'
Beach Town Hall to produce a draft plan for submission to the Town Mayor and Town
Council. They will then hold an advertised public hearing on July 17, 2001, to encourage
public participation in the development of the final product.
'
The net result of the study determined that the storm drains should be removed and
storm water diverted, via environmentally sensitive engineered conveyance, to a
Town of Kure Beach
Ocean Outfall Study

' newly created wetland located in the United States Army Marine Ocean Terminal
Sunny Point (MOTSU) buffer zone along the West side of Pleasure Island.
Obviously the devil is in the details and the above determination followed much
discussion, the body of which is more thoroughly digested herein. Two major issues —
funding and location of the proposed facility — present the greatest obstacles to success.
' With MOTSU agreeing in principle to cooperate and permit use of their buffer zone
(subject of course to US Army policy), the Town must now seek funding to proceed with
' what could be a rather expensive project. The CFCOG has committed to assist in this
endeavor and will remain at the Town's disposal to facilitate future meetings.
' This study has been an important FIRST STEP in addressing the broader issue of storm
water management. As such, funding will also be sought to develop a detailed Storm
Water Policy for the Town, and possibly the Island.
' The Cape Fear COG acknowledges with gratitude the efforts of those who volunteered
their time and resources to make this project a success. Special acknowledgment is
' extended to the North Carolina Division of Coastal Management who funded in part this
study.

Town of Kure Beach
Ocean Outfall Study

Define the Problems
1. Eighteen (18) ocean outfall storm water culverts drain directly into the Atlantic
Ocean at Kure Beach, North Carolina. Storm water discharged from these
culverts is eroding the beach, creating an environmental and safety hazard to
swimmers, and negatively impacts the TourismNacation economy.
' 2. In search for an environmentally sensitive engineered solution, the Town of
Kure Beach agrees with the Federal and State regulatory agencies responsible
for controlling run off that non -discharge storm water controls are preferred,
but the potential cost of such a project is cost prohibitive without outside
funding.
L�
11
1
3. Once funding is secured a suitable location for engineered storm water controls
must be obtained.
What is Storm Water?
Storm water is precipitation that accumulates in natural and or constructed storage and
storm water systems immediately following a rain storm event. In Kure Beach, that
usually means water those ponds up in low areas or drains off impervious surfaces into
storm culverts where it is transported to the Atlantic Ocean or Cape Fear River.
Storm water is a natural occurrence, and where it is not absorbed, it collects on the
surface until it is transported via evaporation, absorption, or run-off. Absorption and
evaporation present the least environmental hazard, while run-off presents the greatest
threats due to erosion and transportation of waterborne pollutants.
Why are the Drains There?
The eighteen- (18) drains that exist today were installed in 1911 when the old roadway
was built. Other drains may have preceded these, but those there today were installed
then by the road -builders. Their purpose is to drain storm water away from the road
surface.
Who Owns them?
Current ownership is debatable, although it is clear the storm drains are not privately
owned, but rather, the North Carolina Department of Transportation — Division of
Highways (DOT) and the Town of Kure Beach shares maintenance of them. DOT
Town of Kure Beach
Ocean Outfall Study

' maintains the drains across their right of way, while the Town maintains the pipes once
they reach the shoreline.
' Recently DOT and the Army Corps of Engineers (ACOE) partnered in the relocation of
the drains at the (former) Hanby Beach area (see map in appendix (c). The Town has
extended the pipes to accommodate beach re -nourishment projects and has kept them
open over the years.
It would be a fair assumption that DOT owns the pipes within their right of way.
Ownership beyond that point is less clear, but clearly public and consequently, a shared
responsibility of those tasked with protecting the public health safety and welfare. The
' drains are in the Town limits, therefore, the Town has taken the lead to remedy the
problem and solicited the partnership of those federal and state agencies that share in the
responsibility and liability the pipes create.
What Are the Issues?
' ❑ Public Health/Safety/Welfare
❑ Environmental
❑ Maintenance and Repair
' ❑ Economic
Public Health, Safety, and Welfare
As discussed in the previous sections, storm water carries non -point biological and
chemical pollutants washed off impervious surfaces of parking lots and streets, some of
which pose a health risk to humans. Direct pollution also may occur when oil and
hazardous substances are dumped into storm drains.
Environmental Issues
'
Water that drains off of impervious surfaces picks up contaminants as it washes across
and carries these contaminants to wherever it flows. Parking lots and streets harbor
petroleum residue as well as bacterial contaminants that concentrate until a rainstorm
'
event washes these pollutants away in storm water. Over a period of time, these non —
point source pollutants (meaning they do not originate from a specific source) alter the
ecosystem of the water body into which they drain, often having a negative impact on the
'
flora and fauna that require clean water to survive.
Much of the shellfish closures are in part, due to storm water run off, according to
'
officials with the NC Shellfish Sanitation Division. Because of the threat of bacterial
contamination, they must post signs warning people of the health risks associated with
swimming in water contaminated by the run-off.
'
Maintenance and Repair
The agencies tasked with the maintenance and repair of the pipes incur substantial
'
expense following major storm events like hurricanes or nor'Easters. Where outflows
leave the culverts, substantial erosion occurs washing away expensive beach sand
pumped onto the beach during re -nourishment projects.
Town of Kure Beach 7
'
Ocean Outfall Study

' Economics
The most damaging economic consequence of the drains has come from the required
posting of signs warning of the potential threat of bacterial contamination from the storm
' water being discharged. While this is necessary for public awareness, these sign posted
along the beachfront at each outfall have resulted in lost revenues to the tourist related
industry result when people choose to go elsewhere due to the threat.

What Has Been Done To Date?
tSpecifically,
it has been determined during this study that while there are existing recent
engineering documents regarding extending or repairing some of the culverts, there has
been no engineered solution that addresses removing the pipes altogether.
There are recent surveys that tie dram locations to the USGS grid.
'
The US ACOE has topographical maps and Arial photo products that show contours as
well as ditches and canals that could be used in diverting the storm water.
'
The Town has geographic information system (GIS) capability and can access various
databases for use in future planning.
DOT may have maps that relate to the current location of pipes and ditches (canals) in the
study area.
During meetings of the committee, Col. Montgomery of MOTSU indicated a desire to
assist the Town by permitting use of portions of the MOTSU buffer for creating wetlands
or other engineered non -discharge solutions. He noted the plan presented a mutually
beneficial opportunity for both the Town and the Army by creating usable open space and
enhancing the environment. This will require careful coordination between the Town and
'
MOTSU, but presents the best opportunity to proceed with a viable solution.

Possible Solutions
The committee determined that there is only one viable long -term solution — that
' being to remove the pipes and divert the storm water to an environmentally
sensitive, engineered, non -discharge storm water controls facility. The most
desirable facility would be the creation of a wetland to collect and detain the storm
' water allowing it to either evaporate or slowly discharge with minimal impact to the
environment.

Options to Consider
C'rente n New Wetland — Retention Area
PRO
❑ Enhance Water Quality
❑ Creates a new wildlife habitat in a time
when there is a net loss
❑ Creates potential opportunity for
development of nature trails
❑ May Qualify for Funding as part of the
new wetlands initiative
❑ MOTSU buffer area very suited for this
type of project
❑ Topographical restrictions are minimal
and could use existing ditches
❑ Plan appears to be compatible with
MOTSU long range goals for the public
use of the buffer
❑ Creates open space and satisfies long
term objectives of the Kure Beach Land
Use Plan
❑ Compatible with the NC DWQ long
term goals by removing the pipes and
creating a non -discharge solution
❑ It is the best environmentally sensitive
engineered solution
❑ May Qualify for Army COE funding
and/or engineering assistance
❑ Compatible with both NC and US
Wildlife agency Goals
❑ Protects shellfish areas from further
pollution from storm water in the Kure
Beach area
❑ Creates opportunity for educational
research and study of wetlands
CON
❑ New wetland may create mosquito problem
❑ Cannot discharge directly into existing
estuarine wetlands because it would lower
salinity and endanger ecosystem
❑ An environmental impact statement (EIS)
would have to be prepared. This may take a
while and could involve issues with
endangered or threatened species.
❑ Historic and Cultural surveys must be
completed and could be a problem for
construction if significant sites are discovered
as the buffer is in close proximity to Civil
War battlegrounds.
❑ Diversion of the water will require obtaining
easements for the ditches or the pipes across
privately held properties.
❑ Funding is not currently available and the
project will be expensive requiring extensive
engineering, permits and approvals.

DESIGN PHASE
❑ Town to Name a project director
A project Director will coordinate Task Force members and direct the consulting staff
in the progression of the project, acting as a point of contact and liaison for the
Council. (Gary is a perfect candidate for this job)
❑ Obtain written permission (easements) from MOTSU to use Buffer
This needs to happen soon as there is a change of Command in July. Gary Owen and
Chris May can work on this ASAP
❑ Obtain Funding for Preparation of Bid Specifications.
The CFCOG will work with the Town and other agencies to locate funding for hiring
a licensed professional engineer to prepare specifications and estimate the potential
cost of the project.
• The Project Engineer shall interview prospective engineer candidates and
recommend a finalist to be approved by the Town.
❑ Prepare a request for proposals (RFP)
Once funding is secured, an engineer should be hired to prepare detailed
specifications and develop an RFP with sufficient engineered detail and supporting
data to ensure potential bidders fully comprehend the scope of the project and every
bidder is bidding on the same concepts.

Gary Owen, a project coordinator for Kure Beach, kneels next to a pipe
that discharges stormwater directly into the Atlantic. The town is seeking
a drainage system that would send rainwater to the undeveloped back
side of Pleasure Island.
KURE BEACH
Town seeks `detour'
for its stormwater
E;y BRIAN FFAGANS
Staff Writer
Kure Beach officials have begun
studying Ways to get rid of 16 pipes
that discharge stormwater directly
into the Atlantic.
The town has hired an engineering
firm to design a drainage system that
would reverse the flow of rainwater
so it goes to the undeveloped back
side of Pleasure Island. And the N.C.
Division of Coastal Management has
chipped in $3,000 to help pay for
meetings with all parties that may
have to be part of a .solution to the
problem.
Federal clean water rules are
expected to one day require towns
such gs Kure Beach to contain and
treat their storm water before it
enters the ocean or the Cape Fear
River.
And the town has another, harder
to ignore incentive to act. Next to one
3-foot-wide pipe emptying into the
surf is a sign warning beach -goers of
possible bacterial pollution after
heavy rains. It's the only such health
warning on the North Carolina shore-
line.
Smaller pipes pop out from under
the sand at the end of streets toward
the southern end of town. They get
clogged with sand and are a nuisance
to repair after storms, said Gary
Owen, a project coordinator for Kure
Beach.
"We know that down the road it
could become necessary, not to men-
tion common sense, to have our.
storm water not drain into the
ocean, he said. "We've still got a
long way, but you've got to walk
before you run."
One possibility is to use the wcl-
land-laced property owned by the
Sunny Point Ocean Military Ter-
minal on the back side of Pleasure
Island. It is part of a blast buffer zone
around the military's primary ammu-
nition terminal on the East Coast.
Kure Beach officials have met with
Sunny Point's commander, and Mr.
Owen said he is open to plans that
would utilize the blast zone to treat or
store storm water.
With the help of the'$3,000 grant,
the Cape Fear Council of Govern-
ments will facilitate discussions
between town officials, • transporta-
tion officials and the Army.Corps of
Engineers, said Haskell Rhett III, .
management service director for the .
council. The N.C. Department of
Transportation maintains the
drainage pipes along U.S. 421 while
the corps keeps up the pipes on the
shore in conjunction with the town's
beach renourishment plan.
A similar challenge faces the town
of Emerald Isle up the coast in Car-
teret County. The beach town has to
pump its storm water into the ocean
after heavy rains to alleviate flooding.
Now officials there must decide
whether to spend $4.2 million for a
storm water system draining 1.6
miles. Roughly $3 million of that is to
buy land for storm water retention. .
The Sunny Pointblast zone, which
can't be developed, may be the saving
grace for Kure Beach.
"We'll try to come up with possible
solutions and look at their cost," Mr.
Rhett said. "It may turn out all the
solutions are too expensive, we don't
know."
