Pond Restoration Plan.
The Pond Project consists of a 10,325 square foot wet pond with a 2,000 square foot forebay located on Flowering Bridge path in the Town of Caswell Beach. The project wet pond and
forebay receives runoff and stormwater drainage from approximately 123 acres and has become filled with silt and algae. The wet pond discharges to a drainage channel that outflows to
the saltwater marsh of Piney Point Creek, the Intracoastal Waterway and Cape Fear River. Tidal influence and saltwater vegetation begin approximately 800 feet downstream from the wet
pond outflow dam.
The goal of the project is to improve the silt filtering capacity of the forebay, the water quality in the wet pond outflow, and increase the stormwater holding capacity of both the wet pond
and forebay by approximately 8,163 cubic feet. The project will include dredging the wet pond and forebay down to the original level (+2 Mean Sea Level) and replacing the nonfunctioning
downstream dam which will improve the holding capacity and water quality that outfalls from the wet pond to the drainage channel and saltwater marshes.
The Caswell Beach Pond project is located within the common area of the Arboretum Homeowners Association neighborhood. There are 96 homes and 6 undeveloped lots that are
affected by untreated stormwater flooding that is acerbated by the lack of capacity in the wet pond and forebay. The maintenance of the wet pond and forebay after restoration will be
administered by the Arboretum Homeowners Association.
The wet pond and forebay due to years of silt buildup lack the ability to treat and retain stormwater runoff during even minor storm events. In its current condition, the wet pond and forebay
are choked with sediment which prohibits the natural action of capturing, retaining, and treating stormwater runoff. Restoration of the Caswell Beach wet pond is considered a stormwater
best management practice in North Carolina. As per Dr. William Hunt, Assistant Professor and Extension Specialist Biological and Agricultural Engineering North Carolina State University,
wet ponds are the most common stormwater management practice in North Carolina and have been constructed since the 1970's in some parts of the state. The Pond Project will address
the objectives of the Environmental Enhancement Grant by improving the water quality of stormwater entering the environmentally sensitive waters of our state.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past? *
Yes No Unknown
4f. List the total estimated acreage of all existing wetlands on the property:
0.35
4g. List the total estimated linear feet of all existing streams on the property:
0
4h. Explain the purpose of the proposed project: *
The goal of the project is to improve the silt filtering capacity of the forebay, the water quality in the wet pond outflow, and increase the stormwater holding capacity of both the wet pond
and forebay by approximately 8,163 cubic feet. The project will include dredging the wet pond and forebay down to the original level (+2 Mean Sea Level) and replacing the nonfunctioning
downstream dam which will improve the holding capacity and water quality that outfalls from the wet pond to the drainage channel and saltwater marshes.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The existing stormwater retention pond is to be dredged to a depth of -2.0 feet increasing the pond's stormwater retention by 5,153 cubic feet. The dredged material will be disposed at an
upland site. A tracked excavator will be used to dredge the pond.
❑ Remove and replace the existing nonfunctional dam on the downstream end of the wet pond with a hand adjustable gate and weir system to regulate wet pond elevation and control
outflow.
❑ Remove (excavate) sediment buildup from wet pond to increase stormwater capacity and water filtering capabilities. Removing approximately 0.5 feet of sediment depth from the current
10,325 square foot footprint of the wet pond will provide an additional 5,162.5 cubic feet of stormwater filtering storage capacity.
❑ Remove (excavate) sediment buildup from the forebay to increase sediment filtering capability and capacity. Removing approximately 1.5 feet of sediment depth from the current 2,000
square foot footprint of the forebay will provide an additional 3,000 cubic feet of stormwater filtering and storage capacity.
❑ Excavated depth of wet pond and forebay will be approximately +2.00 Mean Sea Level.
❑ Dewater each load of excavated sediment (approximately 200 container loads) on site, haul & unload dewatered sediment to offsite upland location.
❑ Remove and replace existing weir and wall outlet structure with a three section 15' concrete outlet structure with wing walls to serve as dam and regulate pond elevation.
❑ Concrete wall - Concrete wall to be installed in three 5' x 4.5' sections; two wing walls and one middle outlet structure.
❑ Weir, gate, and valve assembly to be in outlet structure (middle wall), cast grate 5' x 4.6'.

State of NC Attorney General's Office 2022 Grant Cycle
Environmental Enhancement Grant (EEG) Program
Grant Code CB022CR (Town of Caswell Beach, Caswell Beach Pond Project)
Project Proposal
The Town of Caswell Beach (the Town) is located on the eastern end of Oak Island, one
of the Brunswick Islands in southeastern Brunswick County, North Carolina. The Town is
bounded to the north and northeast by the Atlantic Intracoastal Waterway, coastal
wetlands, (SA) estuarine shellfish waters, NC Marine Fisheries Primary Nursery Areas,
and NC Natural Heritage Areas; to the east by the confluence of the Cape Fear River and
the Atlantic Ocean; to the south by the Atlantic Ocean; and the jurisdiction of the "Town
of Oak Island" to the west.
The town incorporates a total area of 4.1 square miles, with 2.9 square miles of land
area, the remaining geographical area of Caswell Beach includes Significant North
Carolina Natural Heritage areas. The elevations within the town range from sea level to
25+ Mean Sea Level.
During the past decade as building has increased, storm events have intensified, and
high tides have become more prevalent the Town is experiencing flooding that is
overwhelming our stormwater system as well as flooding in areas that did not have
flooding problems 15 years ago. After storm events the neighborhood areas within
Caswell Beach have seen a steady increase in stormwater runoff and flooding.
In 2018 the Town of Caswell Beach initiated a Stormwater/Floodwater Resiliency Plan to
focus on the increasing stormwater flooding throughout the town. Phase one of the
Town's Stormwater/Floodwater Resiliency Plan was to engage our residents in the
process of taking ownership and identifying areas within their communities that were
repeatedly impacted by storm flooding. Through public town meetings and onsite visits,
we gathered information for the plan. With our information in hand, it was evident we

needed to devise a comprehensive holistic plan to move floodwater away from homes
and roadways and improve the quality of the stormwater runoff.
Phase two of our Stormwater/Floodwater Resiliency Plan was to hire a stormwater
engineer to oversee a field elevation survey of the affected areas, review the survey
data, determine where mitigation projects could be done, prioritize the projects and
provide engineered drawings, construction plans and cost estimates for the top five
drainage improvement projects.
Mr. Eric Tomczak P. E. from Proactive Development P.L.L.0 in Wilmington NC was hired
as our Plan engineer.
To secure funding for our Stormwater/Floodwater Resiliency Plan, in August 2019 the
Town applied to Golden LEAF Foundation for funding through the Golden LEAF
Hurricane Florence Recovery Grant Program. In June of 2020 the Town gratefully
accepted Golden LEAF funding to create our Stormwater/Floodwater Resiliency Plan.
The Caswell Beach Pond project is one of the five drainage improvement projects that
make up the Stormwater/Floodwater Mitigation Plan.
Pond Restoration Plan:
The Pond Project consists of a 10,325 square foot wet pond with a 2,000 square foot
forebay located on Flowering Bridge path in the Town of Caswell Beach. The project wet
pond and forebay receives runoff and stormwater drainage from approximately 123
acres and has become filled with silt and algae.' The wet pond discharges to a drainage
channel that outflows to the saltwater marsh of Piney Point Creek, the Intracoastal
Waterway and Cape Fear River. Tidal influence and saltwater vegetation begin
approximately 800 feet downstream from the wet pond outflow dam.z
The goal of the project is to improve the silt filtering capacity of the forebay, the water
quality in the wet pond outflow, and increase the stormwater holding capacity of both
the wet pond and forebay by approximately 8,163 cubic feet. The project will include
dredging the wet pond and forebay down to the original level (+2 Mean Sea Level) and
replacing the nonfunctioning downstream dam which will improve the holding capacity

and water quality that outfalls from the wet pond to the drainage channel and saltwater
marshes.
The Caswell Beach Pond project is located within the common area of the Arboretum
Homeowners Association neighborhood. There are 96 homes and 6 undeveloped lots
that are affected by untreated stormwater flooding that is acerbated by the lack of
capacity in the wet pond and forebay. Although the maintenance of the wet pond is the
responsibility of the Arboretum Homeowners Association, the project design,
application for funding and the actual project oversight is being done by the Town of
Caswell Beach. The maintenance of the wet pond and forebay after restoration will be
administered by the Arboretum Homeowners Association.
The wet pond and forebay due to years of silt buildup lack the ability to treat and retain
stormwater runoff during even minor storm events. In its current condition, the wet
pond and forebay are choaked with sediment which prohibits the natural action of
capturing, retaining, and treating stormwater runoff. Restoration of the Caswell Beach
wet pond is considered a stormwater best management practice in North Carolina. As
per Dr. William Hunt, Assistant Professor and Extension Specialist Biological and
Agricultural Engineering North Carolina State University, wet ponds are the most
common stormwater management practice in North Carolina and have been
constructed since the 1970's in some parts of the state.' The Pond Project will address
the objectives of the Environmental Enhancement Grant by improving the water quality
of stormwater entering the environmentally sensitive waters of our state.
Project Outcomes:
• Restoration of the forebay to its original purpose of capturing and filtering
sediments and runoff.
• Increased stormwater holding capacity of the wet pond and forebay.
• Regaining the ability to control the pond outflow by rebuilding the weir system
and downstream dam.
• Improve the filtering capability of the wet pond and forebay for stormwater
pollutants before the stormwater discharges into the sensitive waters surround
the Town of Caswell Beach.

filtering capability and capacity. Removing approximately 1.5 feet of sediment
depth from the current 2,000 square foot footprint of the forebay will provide an
additional 3,000 cubic feet of stormwater filtering and storage capacity.
• Excavated depth of wet pond and forebay will be approximately +2.00 Mean Sea
Leve 1.
• Dewater each load of excavated sediment (approximately 200 container loads)
on site, haul & unload dewatered sediment to offsite upland location.
Replacement of Dam Weir System Will Include: (please see attachment CB022CR
Engineered Project Design Pg. 8, #10 OUTLET STRUCTURE DETAILS)
Downstream Dam (weir & gate):
• Remove and replace existing weir and wall outlet structure with a three section
15' concrete outlet structure with wing walls to serve as dam and regulate pond
elevation.
• Concrete wall - Concrete wall to be installed in three 5' x 4.5' sections; two wing
walls and one middle outlet structure.
• Weir, gate, and valve assembly to be in outlet structure (middle wall), cast grate

Ben,
It looks like you are asking about the circled ponds below. Assuming those are the ones in SW8 880620, (which is a low density permit that did not
require them) and assuming that they are not natural ponds/wetlands (which is unlikely because there are fountains), you do not need any approval from
State Stormwater for maintenance dredging.
Thanks,

So to dredge out about -1.5 from the "amenity or golf course ponds" do we need any documentation allowing for the maintenance?

Dear Mr. Brink:
Your best course of action is to do a file review. If you look at the Active Storwater Permits Map online:
Active Stormwater Permits Map (arcgis.com)
There are several permits that may apply.
SW8031121 Oak Island Golf and Country Club Phase II
SW8100725 Fairway Drive Flood Relief Project
SW8180203 Ryder Cup Lane SD
But most likely SW8 880620 Arboretum. Attached is an email sent last year to Jeff Griffin of Caswell Beach from Kelly Johnsont. I think he is speaking
of the same ponds.

Hi Ms. Hall and Mr. Lambe,
The Arboretum Community Association is hoping to dredge out a pond in Caswell Beach. This email is to ask whether these ponds are considered
stormwater ponds (any permitting history?) or are they under USACE jurisdiction? Please see attachment for location map and email from Gary
Beecher (USAGE). The scope of the project is in a 'red square" with an arrow pointing to the pond on an engineered drawing.
Thank you so much for any information on how to move forward with plans to deepen the ponds. Any help is appreciated. Kind regards.
All the best,

Good afternoon all,
Ben copied me on the previous e-mail that was sent about these ponds.
Since SW8 880620 is a "low Density" stormwater permit then these (2) ponds are not part of the State Stormwater Permit/treatment plan? So there
probably isn't a state mandated maintenance requirement for the ponds?
Are there any engineered plans for the ponds (that show elevations and as built plans)?
The Town of Caswell Beach wants to muck them out so they can handle more runoff or flood water? To me it looks like the ponds were constructed by
damning up a coastal stream (years ago). Is the stream feature part of the stormwater plan? Is this feature considered a low density swale? Low Density
should mostly consist of grassed swales, but since this is an older 1988 project the coastal storm water rules might have been different.
I appreciate any help that you can give us on this site/project. If the ponds are determined to be Jurisdictional Waters of the U.S then a permit from the
Corps would be required to muck them out. If they are part of a State Storm Water Permit/plan then the Corps would not require a permit or notification for
the proposed work. (The Corps doesn't regulate stormwater features). Mr. Brink is performing his due diligence in learning all he can about this site.
Thanks again for the assistance, it is much appreciated.
Respectfully,
Gary

Ben,
Those are interesting ponds.
They basically took a stream, dammed parts of it up to create the ponds. Then ran their storm water into them via gutters and roadways. I think the
ponds also function as flood control features, but I'm not sure.
Ofcourse this was done pre -clean water act. (60's 70's ?)

I would check with the State DEQ (stormwater section) to see if there is actually a stormwater permit for the ponds. I'll check on my end also. If a active
stormwater permit exists, then I might walk away from the ponds as being Jurisdictional (The Corps doesn't regulate stormwater ponds/features)
But currently I'm calling the ponds Jurisdictional so a permit will be required to "muck" them out. They can't be mucked out any deeper then the original
depth. (that will be hard to determine since there are no original plans on the ponds)
-Also the ponds are possibly home to several American Alligators. The Alligator is an endangered species in NC. They would have to be trapped and
safely removed before any work takes place in the ponds. (USFWS will need to be consulted about the work in the ponds to get their input on how to
safely and legally deal with the Alligators)
So its not just a pond mucking out job, there are several different potential Jurisdictional layers to this project.
I'll let you know what I find out on my end.

The post construction stormwater program has no jurisdiction over those ponds.
Our files are considered public record and a file review can be scheduled to look to see if any details are provided regarding any existing features or

Do the following:
1. fill out and sign PCN form
2. Will need plans that show where the work will take place (impacts ,etc.)
3. submit the form electronically
I don't know if the state will issue a 401 certification for this, probably just a 401 general certification. The 401 individual certification is for larger projects
not for maintenance work.

Good afternoon Ben,
Based on the scope of work the project will likely require an individual water quality certification from the DWR, see attached certification and thresholds.
You are required to request a pre -filing meeting 30 days prior to submission of your ePCN application. The correspondence received on May 10 ill
satisfy the pre -filing requirement and you may submit you application after June 9, 2022.
The downstream waters of Piney Point Creek as classified as SA;HQW. The application should clearly state where and how water will be managed. This
should include any water that must be pumped out of the pond to complete the work and changes in water storage volumes should be provided. Please
detail any changes that will be made to the outlet structures as well.
Work on the ponds was previously authorized by DWR project number 19950255, not sure if Gary has an old Action ID for this site. Feel free to call or
email me if you have any questions.
Sincerely,
Holley Snider.

2. The permit issued shall continue in force and effect until revoked or terminated.
The permit may be modified, revoked and reissued or terminated for cause. The filing of

considered on its merits, and may or may not be approved.
6. The permittee is responsible for compliance with all permit conditions until such time as
the Division approves the permit transfer request. Transfers to third parties by the
permittee where the required documentation has not been submitted to the Division does

25% Low Density
Classification: SA
Cool, sunny
a. A service road has been constructed beside the entrance bridge, not shown on the
approved plan.
b. The road section in the subdivision has been altered from that which was approved.
Islands have been created where the road splits into two parts. This type of road
section was not shown on the approved plan.
C. The layout of the subdivision differs from what was approved. The area near the cul-
de-sacs named Mimosa Place and Narcissus Mews on the plans has been altered. It
appears that Narcissus Mews has been deleted; another sac has been added
because the road no longer connects through; and Mimosa Place has been
lengthened.
d. With the street layout changes, the lot layout and possibly the number of lots, has
also changed.
e. A parking lot has been added to the recreation area that is not shown on the
approved plan.
PE Certification Received? n/a Deed Restrictions Received? NO
Required Action:
a. Please submit a stormwater management permit modification to account for these
changes, and demonstrate continued compliance with the 25% low density option. A
completed submittal includes 2 sets of complete, revised plans with all road and cul-
de-sac details, a completed application and supplement, design calculations, a map
of the recreation area, and a $420.00 application fee.
b. If there are now more lots than the approved 102, the built -upon area per lot will need
to be reduced to account for it, and the revised number recorded with the Register of
Deeds.
