subject to the conditions and limitations as specified therein. Please pay special attention to the
Operation and Maintenance requirements in this permit. Failure to establish an adequate system
for operation and maintenance of the stormwater management system will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of a written petition, conforming to Chapter

approval from the Division.
2. The permittee is responsible for verifying that the proposed built-upon area for
the entire lot, including driveways and sidewalks, does not exceed the allowable
built-upon area. Once the lot transfer is complete, the built-upon area may not be
revised without approval from the Division of Water Quality, and responsibility for
meeting the built-upon area limit is transferred to the individual property owner.
3. If an Architectural Review Board or Committee is required to review plans for
compliance with the BUA limit, the plans reviewed must include all proposed
built-upon area. Any approvals given by the Board do not relieve the homeowner
of the responsibility to maintain compliance with the permitted BUA limit.

revised plans, specifications, and calculations prior to construction, for any
modification to the approved plans, including, but not limited to, those listed
below:
a. Any revision to the approved plans, regardless of size.
b. Project name change.. .
c. Transfer of ownership.
d. Redesign or addition to the approved amount of built-upon area.
e. Further subdivision, acquisition, or sale of all or part of the project area.

permit was sought.
f. Filling in, altering, or piping of any vegetative conveyance shown on the
approved plan.
5. The Director may determine that other revisions to the project should require a
modification to the permit.
6. The Director may notify the permittee when the permitted site does not meet one
or more of the minimum requirements of the permit. Within the time frame
specified in the notice, the permittee shall submit a written time schedule to the
Director for modifying the site to meet minimum requirements. The permittee
shall provide copies of revised plans and certification in writing to the Director
that the changes have been made.
7. The stormwater management system shall be constructed in its entirety,
vegetated and operational for its intended use prior to the construction of any
built-upon surface.
8. During construction, erosion shall be kept to a minimum and any eroded areas of
the system will be repaired immediately.
9. Upon completion of construction, prior to issuance of a Certificate of Occupancy,
and prior to operation of this permitted facility, a certification must be received
from an appropriate designer for the system installed certifying that the permitted
facility has been installed in accordance with this permit, the approved pians and

parking areas, but does not include raised, open wood decking, or the
water surface of swimming pools.
g. Lots within CAMA's Area of Environmental Concern may be subject to a

12.6 Stormwater Runoff Rules. The following covenants in this Section 12.6
are intended to ensure ongoing compliance with the Stormwater Management Permit(the
"Permit") issued by the North Carolina Division of Water under 15A NCAC 2H.1000,
evidencing the approval of the stormwater plan for the Property (the "Approved Plan").
(a) The State of North Carolina is made a beneficiary of the covenants
contained in this Section 12.6, to the extent necessary to maintain compliance with the
Permit.
(b) The covenants pertaining to stormwater in this Section 12.6 may not be
altered or rescinded without the express written consent of the Division of Water Quality.
(c) Alternation of the drainage as shown on the Approved Plan may not take
place without the concurrence of the Division of Water Quality.
(d) Filling in, piping or altering any designated 5:1 curb outlet swale
associated with the Property is prohibited by any persons.
(e) The Approved Plan for this Property proposes a curb outlet system. Each
designated curb outlet swale shown on the Approved Plan must be maintained at a
minimum of 100' long with 5:1 (H:V) side slopes or flatter, have a longitudinal slope no
steeper than 5%, carry the flow from a 10 year storm in a non-erosive manner, and
maintain a dense vegetated cover.
(f) The maximum allowable built-upon area per lot is 6.000 square feet. This
allotted amount includes any built-upon area constructed within the lot property
boundaries,and that portion of the right-of-way between the front lot line and the edge of
the pavement. Built upon area includes, but is not limited .to, structures, asphalt,
concrete, gravel, brick, stone, slate, coquina and parking are, but does not include raised,
open wood decking, or the water surface of swimming pools.
(g) All stormwater runoff from the built-upon areas on each Unit within the
Property must drain into the permitted stormwater system. This may be accomplished
through providing roof drain gutters which drain toward the street, grading the land to
drain toward the street, and grading perimeter swales to collect runoff and directing them
into the stormwater system. Units that will naturally drain into the system are not
required to provide these additional measures.
3.4 Except as specifically set out in this Supplemental Declaration, the remaining
provisions of the Master Declaration remain as set out therein.

Ocean Isle Beach, North Carolina
Modification of Stormwater Plan for Approval --'' SW8 030724 Map
Dear Ms. Lewis:
On behalf of Coastal Communities © Ocean Ridge Plantation, Inc., we
are pleased to submit for your review and approval Ocean Ridge Plantation -
Phase IV, Section 6. Please find enclosed two (2) copies each of the application
and supplements, stormwater plans, stormwater calculations, and one (1)
check in the amount of$420.00 to cover the application fee.
Phase IV, Section 6 is now composed of 128 single family lots and
roadways. The stormwater runoff is to be treated in 5 Stormwater Ponds.
An update of the Overall Phase IV Stormwater Plan is also being
submitted under separate cover.
We appreciate your attention in this matter. Should you have any
comments or require any additional information, please do not hesitate to
contact our office at your convenience.
