Plan Revision
Kelly,
The following is in response to the Application Return dated August 24, 2009 for the above
referenced project.
1. Outlet Revisions: The proposal requests to alter several pond outlets, but does not
speck which outlets will change or list the specific requested changes to those outlets. In
your resubmittal please speck the changes you are requesting for each outlet that you
plan to change. If the outlet structures will be altered such that the driving head through
the drawdown orifice(s) will change, then it will affect the drawdown time of the
ponds(s), which would require a permit modification.
Pond#6
✓- o The orifice pipe material was changed from steel to CIP.
/ -o The pond bottom was incorrectly labeled as 16.0' msl on the previously
permitted plans.The bottom elevation has been correctly labeled as 15.0' msl on
� / the revised stormwater plans.
V - o The top of pond elevation was changed from 30.0' msl to 31.0' msl.
✓ o The emergency spillway elevation was changed from 29.5' msl to 30.0' msl.
✓- o The spillway width was changed from 30'to 40'.
o The outlet structure dimensions were changed from 4' x 3' to 5' x 5'.
o The width of the cut out weir in the outlet structure was changed from 2' to 3'.
Please note that the above changes DO NOT affect the orifice size,permanent pool
elevation,or temporary pool elevation.Therefore,there has been no change to the
driving head or drawdown calculations.
Pond#9
o The orifice pipe material was changed from steel to CIP.
o The outlet structure dimensions were changed from 1.5' x 1.5' to 3' x 3'.
Please note that the above changes DO NOT affect the orifice size,permanent pool
elevation,or temporary pool elevation.Therefore,there has been no change to the
driving head or drawdown calculations.

✓ —o The orifice pipe material was changed from steel to CIP.
—o The top of the riser structure was changed from 33.50' msl to 35.5'msl.
o A 2'x2' rectangular weir was added at the temporary pool elevation of 33.50'
msl.
o The outlet pipe was changed from 30"HDPE to 36"HDPE
o The downstream invert of the outlet pipe was changed from 30.5' msl to 26.75'
msl.
o The pond bottom was incorrectly labeled as 18.0' msl on the previously
permitted plans. The bottom elevation has been correctly labeled as 17.0' msl on
the revised stormwater plans.
o A detail showing the Pond Outlet Front View was added to the plan.
Please note that the above changes DO NOT affect the orifice size,permanent pool
elevation,or temporary pool elevation.Therefore,there has been no change to the
driving head or drawdown calculations.
Pond#13
✓. o The orifice pipe material was changed from steel to CIP.
J - o The upstream invert of the outlet pipe was changed from 27.75' msl to 27.50'
msl.
o The downstream invert of the outlet pipe was changed from 27.50' msl to 27.25'
Kok 6 msl.
Please note that the above changes DO NOT affect the orifice size,permanent pool
elevation,or temporary pool elevation.Therefore,there has been no change to the
driving head or drawdown calculations.
Pond#14
✓ - o The orifice pipe material was changed from steel to CIP.
o The outlet pipe was changed from 30"HDPE to 36"HDPE
o The upstream invert of the outlet pipe was changed from 42.0' msl to 41.0' msl.
V_ o The downstream invert of the outlet pipe was changed from 40.08' msl to 39.0'

2. Pond#11: The proposed change is to reconfigure the pond such that the forebay moves
from the south side to the north side of the pond. The letter indicates that the forebay
volume is maintained between the pond currently permitted and the proposed pond. This
is a substantial change from the current design and many variables are likely to have
been changed. For instance, the current permit uses Option 2 for determining the
average depth. Variables used in that calculation include the surface area of the bottom
of the shelf, the surface area of the permanent pool, and the surface area of the bottom of
the pond. All of these variables will likely change by the proposed reconfiguration. The
appropriate method of making such substantial changes is through a permit modification
rather than a revision.
This plan revision does not change any contour surface areas below or above the normal
pool. The table below shows the contour surface areas that were originally permitted and
the contour surface areas in the proposed plan revision.

NOT change as a result of this plan revision.

3. Rule subject: The permit is currently issued under the. The project will continue to be
permitted under the 1995 rule as long as there is no "...increase[in]the net area of built
upon area within the project site or[no]increase[in]the overall size of the stormwater
controls that have been previously approved,"per SL2008-211, Section 2(d)(5). You are
not proposing to increase the impervious area or the size of the pond, but please note that
if the overall size of the pond were to increase it would be permitted under the 2008
Coastal Rule (SL2008-211).
Vested rights have been established for Ocean Ridge Plantation Phase VI in accordance
with G.S. 153A-344.1. A Planned Unit Development(PUD)Master Plan was approved
for all of Ocean Ridge Plantation Phase VI by the Town of Sunset Beach on June 15,
2006 and extended on June 26,2008. Copies of the approval letters are enclosed. Based
on Session Law 2008-211 (Senate Bill 1967),the entire project is vested;therefore, all
permitted phases and future phases are only subject to the 1995 Coastal Rule(15A
NCAC 2H .1005, effective September 1, 1995).
In addition,we are not proposing to increase the built upon area or expand the size of the
treatment system.
I trust that this information is sufficient to issue this plan revision for the subject stormwater
permit;however, if you have any questions or need any additional information please do not
hesitate to contact me.

Ocean Ridge, Phase VI, Section 2/SW8 080533
Brunswick County
Dear Ms. Noble:
On August 19, 2009, the Division received an incomplete State Stormwater Management
Application for the project listed above. The application is being returned because the
application package lacked the necessary elements to accept it for review. Please provide the
following information upon the next submittal of this application package:
1. Outlet revisions: The proposal requests to alter several pond outlets, but does not
specify which outlets will change or list the specific requested changes to those outlets.
In your resubmittal please specify the changes you are requesting for each outlet that
you plan to change. If the outlet structures will be altered such that the driving head
through the drawdown orifice(s)will change, then it will affect the drawdown time of the
pond(s), which would require a permit modification.
2. Pond 11: The proposed change is to reconfigure the pond such that the forebay moves
from the south side to the north side of the pond. The letter indicates that the forebay
volume is maintained between the pond currently permitted and the proposed pond.
This is a substantial change from the current design and many variables are likely to
have been changed. For instance, the current permit uses Option 2 for determining the
average depth. Variables used in that calculation include the surface area at the bottom
of the shelf, the surface area of the permanent pool, and the surface area of the bottom
of the pond. All of these variables will likely change by the proposed reconfiguration.
The appropriate method of making such substantial changes is through a permit
modification rather than a revision.
3. Rule subject: The permit is currently issued under the 1995 Coastal Rule (15A NCAC
2H .1005, effective September 1, 1995). The project will continue to be permitted under
the 1995 rule as long as there is no, "...increase [in]the net area of built upon area
within the project site or[no] increase [in]the overall size of the stormwater controls that
have been previously approved," per SL2008-211, Section 2(d)(5). You are not
proposing to increase the impervious area or the size of the pond, but please note that if
the overall size of the pond were to increase it would be permitted under the 2008
Coastal Rule (SL2008-211).

DWQ Stormwater Permit Number: SW8 080533
Plan Revision
To Whom It May Concern:
We are submitting a Plan Revision to the above stormwater permit.
The primary intent of this plan revision is to reverse the direction of Pond 11 as a result of
discrepancies between the drainage easements shown on the approved stormwater plans and those
shown on the recorded Maps for Record.
Pond 11 was originally permitted with the forebay on the south side of the pond and the main
pool and outlet on the north side of the pond.As a result of this revision the forebay is now on the
north side of the pond and the main pool and outlet are on the south side of the pond.
Please note that the forebay grading under the normal pool has been revised such that the
modified forebay volume matches the originally permitted forebay volume. Therefore,the
originally approved calculations and supplements still apply and there is no change to the
permitted values or functionality of this water quality pond.
Additionally,this plan revision modifies several pond outlets in order to meet Brunswick County
stormwater attenuation requirements. Please note that the proposed changes to the outlet
structures do not in anyway affect the permitted water quality ponds as all orifice sizes and
elevations and all temporary pool elevations remain unchanged. The revised outlets are reflected
on the modified plan set included with this plan revision submittal. This project is vested under
the 1995 Coastal Stormwater rules and the pre/post requirements do not apply.
I trust that this information is sufficient to issue this plan revision for the subject stormwater
permit; however, if you have any questions or need any additional information please do not
hesitate to contact me.
Sincerely
