Narrative/Project Description, (Brunswick Plantation - North Addition):
The subject project is located in southeast Brunswick County. The subject project
Brunswick Plantation - North Addition is just north of the existing Brunswick Plantation.
Brunswick Plantation - North Addition is a residential project and consists of single family lots,
two multi -family developments, 8 holes of golf, and an amenity center. The single family
developments are divided into Phases 1-3, and the multi-famly developments are Phases 4 & 5.
Development of the North Addition will be accompanied with curb and guttered roadways with
frame and grate inlets and piping. Stormwater Ponds have been engineered for treatment. The
overall flow of the project is from south to north and into the Caw Caw Canal. Upstream ponds
are connected in series before entering an engineered stormwater pond in most cases.
Stormwater Pond # 1 consists of two large golf course ponds. The treatment pond is
divided by two golf holes. The two large golf course ponds are equalized by 2 - 36" culverts. Six
(6) upstream ponds are connected in series and enter ,a forebay of Stormwater Pond # 1. Each of
r
these upstream ponds will act as a forebay. Stomwater is Collected and piped into the
upstream ponds. Each of these upstream ponds is routed into a forebay of Stormwater Pond
# 1. Stormwater Pond # 1 is designed to treat the drainage areas for each of these upstream
ponds as well as for the drainage area of Stormwater Pond # 1. Stormwater Pond # l is also
designed for future Multi -Family development (Considered Off -Site). Stormwater Pond #1 outlets
into the Caw Caw Canal.
Stormwater Pond #2 is also a two pond Stormwater Pond with two forebays. Single
family lots, roadway areas, and golf course areas are treated in Stormwater Pond #2. Neither,
Multi -Family flows or off -site flow enters Stormwater Pond _#2. Stormwater Pond #2 outlets
into the Caw Caw Canal.
Stormwater Pond #3 is on the golf course and treats single family lots, roadways, golf
course, and future Multi -Family development (Considered Off -Site). Stormwater Pond #3 outlets
into a piping system that is proposed through the project.
In the pre -development condition there is a ditch that runs through the project carrying
off -site water into the Caw Caw Canal. This ditch will now be piped through the project and
into the Caw Caw Canal. There is no untreated water from the project entering this piping
system. Stormwater Pond #3 outlets into this piping system. A future Stormwater Pond that
will be engineered to treat a future Multi-li amilly development will also enter this Off -Site piping
system. Another feature about this piping system is that it runs through the forebay berm of
Stormwater Pond #2. The pipe will be well below the top of the forebay berm and have no
adverse effects on Stormwater Pond #2. Headwater calculations show that using one pipe to
convey this water will cause water to back-up in the pipe. Therefore, it is proposed to construct
a second 48" pipe to reduce the tailwater conditions.

Narrative/Project Description, (Brunswick Plantation - North Addition):
The subject project is located in southeast Brunswick County. The
subject project Brunswick Plantation - North Addition is just north of the
existing Brunswick Plantation. Brunswick Plantation - North Addition is an
Overall Low Density project and consists of single family subdivisions, one
multi -family development, 8 holes of golf, and an amenity center. The single
family developments are divided into Sections 1-5, and the multi-famly
development is Section 6. Each section of the North Addition will be submitted
for its own stormwater permit. The Overall Stormwater Plan will be updated
and submitted with each section submittal.
Development of the North Addition will be accompanied with curb and
guttered roadways with frame and grate inlets and piping. A combination of
Curb Outlet Swales and Stormwater Ponds will be engineered for treatment.
The overall flow of the project is from south to north and into the Caw Caw
Canal. There are existing perimeter ditches at the property boundaries that
convey stormwater to the Caw Caw Canal. Upstream ponds will connectoo in
series before entering an engineered stormwater pond in some cases.
This submittal is for an Overall Low Density Stormwater Permit for
Brunswick Plantation - North Addition.

O.K., add that condition. We just wanted to get the Overall Plan
approved as Low Density. We intend to submit detailed plans for
Sections 1-5, that include engineered Stormwater Ponds and
Vegetative Swales, by the end of October. An update of that
Overall Plan will be included with the submittal of Sections 1-5.
Thanks, Jason

You are proposing to use curb outlet swales within this project.
If I were to issue a permit without the supplement, technically,
you could build the project as shown on the overall plan without
further permits from us.
However, what I can do is put specific conditions in the permit
which acknowledge that a curb outlet system is proposed, but that
nothing can be built (not even the main access road) until the
detailed plans and curb outlet supplement are submitted and
approved.

Jason Clark wrote:
Linda.
We are not showing any curb outlet swales on the Overall Plan.
Curb outlet swales and Stormwater Ponds will be used with the
design of each Section. This plan is to get a Low Density
Overall Stormwater Permit. We were trying go do this
development like we have been doing Ocean Ridge Plantation (An
Overall Plan & Overall Low Density Permit, and each Section has
its own individual Stormwater Permit). I can submit to you a
Curb Outlet Supplement, but page 2 would be blank. Section 1
and maybe all of the single family sections will be submitted
soon for their own Stormwater Permit with stormwater ponds and
curb outlet swales and all necessary supplements. I guess I'm
not sure why a curb outlet swale is required for an Overall. how
Density Permit. Can you please clarify what I need to send
you.

Brunswick Plantation - North Addition - Phases 1, 2, and 3. This submittal

On Wednesday, December 3, 1 e-mailed you about having this submittal
replace the previous Overall submittal. You responded that since the permit
for the Overall Stormwater Permit hasn't been issued that this submittal could
replace the Overall Plan. The Plans enclosed propose that all stormwater from
the project be treated in engineered stormwater ponds. Curb outlet swales are
not being used for this project. Since all stormwater is being treated in ponds
there is no need for an overall low density permit. Phases 4 and 5 will be
multi -family tracts that will be submitted separately for their own stormwater
permits.

would like to replace that second submittal with this one. This submittal is for
Phase I of the project only. It does, however, include the design of 4 .large
