Re: Summerwind Plantation Subdivision-Phase 1-A
Stormwater Management Statement and Plan
Dear Mr. Mikesh:
We have reviewed the responses to the plan review letter dated August 2, 2007 and the
revised information to the stormwater management for the proposed Summerwind
Plantation Subdivision-Phase 1A. The stormwater management plan has been approved
with the following stipulations:
1. Please be advised that the total nitrogen calculations must be revised as
subsequent phases are proposed for development.
2. Please be reminded that attenuation and downstream impacts must be fully
addressed for all future phases of the development.
A copy of this letter will be forwarded to the Planning Office for their files. If you have
any questions or need additional information, please contact me at [phone] or by
email at [e-mail].
Sincerely,

Re: Summerwind Plantation Subdivision Phase I-A
Storm water Management Plan Statement and Plan
Response to County Revision Request dated 8/2/2007
Dear Ms. Coats:
Listed below are your plan review comments and our responses from your August 2, 2007 letter to Parker
Development Limited.
1. A fence must be installed around the proposed wet detention pond.
Response- We have incorporated a 6 ft tall chain link fence without barbed wire using your sanitary
sewer standard detail as shown on sheet D14 of the plans.
2. A drainage and access easement to and around the proposed detention facility must be identified on the
final plat.
Response- A twenty (20) ft width drainage and access easement has been provided as requested.
Prior to recordation of the final plat, a recorded inspection and maintenance agreement must be
provided for the wet detention pond.
Response- A copy of an executed standard state form of agreement for the proposed wet pond is
attached for your review. If you find it to be satisfactory, please advise us so it can be recorded in the
registrar of deeds office.
4. Drainage and access easements must be provided to and around the proposed Stormtech devices.
Response- The use of Stormtech devices is not currently planned for the community.
Prior to recordation of the final plat, a recorded inspection and maintenance agreement must be
provided for the proposed Stormtech devices.
Response- The use of Stormtech devices is not currently planned for the community.
6. Please provide a detail for the proposed arch culvert on Street "B".
559 Jones Franklin Road
Suite 164 Phone: [phone]
Raleigh, North Carolina 27606 Fax: [phone]
[e-mail]
Response- The proposed arch culvert has been replaced with a cored span bridge.
7. Please provide revised Total Nitrogen Calculations for Phase I-A (indicating the 25% nitrogen reduction
for the entire drainage area to the wet pond).
Response- Please see attached nitrogen summary calculations for Phase I-A.
Please be advised that the total nitrogen calculations must be revised as subsequent phases are
proposed for development.
Response- Request for additional information is acknowledged and will be submitted with the Phase IB
storm water submittals.
9. Please provide revised impervious area calculations accounting for the proposed pervious pavers. In
addition, these calculations should provide impervious area limits for each lot and must be approved
prior to recordation of the final plat for phase IA. The impervious area limits for each lot must be
indicated on the final plat.
Response- Pervious pavers are currently not proposed for use. Impervious area limits are being shown
on the final plats as they are recorded for each section of the project.
10. Please be reminded that attenuation and downstream impacts must be addressed for all future phases
of the development.
Response- Flow attenuation is being addressed with BMP design for each drainage sub basin. Please see
the attached calculations for BMP#1 which is a part of Phase IA.
11. Please be advised that the project includes onsite wetlands and buffered streams. According to the
design professionals, these areas will not be disturbed to any extent requiring state and federal 401/404
permits. During construction adequate measures must be provided to prevent disturbance of these
areas.
Response- Since this review was issued, this issue has been reevaluated and appropriate state and
federal permits have been applied for. The USACOE did not respond within the required time period for
the Phase IA disturbance and therefore this activity is deemed permitted by regulation. The state
permits are currently under review and you will be provided with a copy of the approval letter when it
has been issued.
12. Please provide a copy of the recorded restrictive covenants noting who will be responsible for
maintenance of all drainage facilities located outside of the proposed NCDOT right of way.
Response- please see the attached copy of the restrictive covenants.

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BW. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BW.
'The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check ore):
2 does M does not incorporate a vegetated filter at the outlet.
This system (gheck ane):
? does [? does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin,
- If the basin must be drained for an emergency or to perform maintenance, the
flusiung of sediment through the emergency drain should be minimized to the
maximum extent practical.
Once a year, a dam safety expert should inspect the embankment.
!After the wet detention Pond is:established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

same may be amended from time to time. Every Owner of real property within Summerwind

Townhouse Residential Use, (iii) Recreational Use, (iv) Master and Neighborhood Common
Areas and (v) Natural Open Space Use. The foregoing list of classifications may be amended
from time to time, in accordance with procedures prescribed by this Declaration and by
applicable federal, state and local law. Future amendments to the foregoing list of classifications
may include such other residential or other related uses, including, without limitation,
condominium uses, as may hereafter be authorized pursuant to a Supplemental Declaration, as
well as such non-residential or other related uses, including, without limitation, Commercial
Uses, as may hereafter be authorized pursuant to a Supplemental Declaration. For purposes of this
paragraph, "Commercial Uses" shall mean the use of any Parcel or portion thereof which is
owned by one person or entity or by a group of persons and/or entities for one or more
commercial purposes allowed by the Master Community, including, without limitation, the
following: apartments, assisted living facilities, general and professional offices, and shopping
centers, provided, however that Commercial Uses shall not be allowed on any Common Areas or
on other areas or facilities of common use which are owned by any superior or subordinate
owners' association or which are owned in common by residential condominium owners. For
purposes of this paragraph, "Recreational Uses" shall be deemed to include use of the
Recreational Facilities for their intended purposes.
Declarant reserves the right, without obligation and without the further consent of the
Association or its Members, to incorporate all or part of the Additional Property (as hereinafter
defined) into the Community and in doing so to subject such part or entirety of the Additional
Property to this Declaration, as more particularly described in Section 11.1 hereof.
In accordance with Article XII hereof, Declarant reserves the right, without further consent of
the Association or its Members, to amend this Declaration to withdraw any unimproved portions
of real property from the scope of this Declaration.
As the development of Summerwind Plantation proceeds, Declarant, as it deems appropriate
and without incurring any obligation to do so, intends (i) to Record various subdivision plats, (ii)
to dedicate to public use, or to retain for private use and convey to the Association, all or part of
the Additional Property which is used for streets, roadways, drainage, flood control and general
public use and (iii) as more particularly described in Article XI hereof, to record Supplemental
Declarations with respect to all or part of the Additional Property which may (a) subject such
property to this Declaration, (b) designate the purpose(s) for which such portions of the
Additional Property may be used and (c) set forth additional covenants, conditions and
restrictions applicable to such portions of the Additional Property.

It is acknowledged that because the Community is part of the Master Community, the
Community and the Governing Documents are subject and subordinate to the Master Declaration
and the authority of the Master Association (as hereinafter defined). Pursuant to the Master
Declaration, the Master Delegate will represent the Community in the Master Association, but
none of Declarant, the Association nor the Master Delegate has, or purports to have, control over
the Master Association, or the ability to cause amendments to be made to the Master Declaration
or to any other documents governing the Master Community.
Any Neighborhood within the Community may choose to enact additional restrictions or
provisions with respect to a Lot or group of Lots within the Neighborhood, provided the same are
more restrictive than the provisions of this Declaration, unless written consent is obtained in
accordance with Section 6.4(a) hereof. If written consent pursuant to Section 6.4(a) hereof is not
obtained with respect to additional restrictions for a Neighborhood, then between this Declaration
and any additional restrictions or provisions enacted by a Neighborhood, the more restrictive of
the two will control. If written consent pursuant to Section 6.4(a) hereof is obtained with respect
to additional restrictions for a Neighborhood, then between this Declaration and any
additional restrictions or provisions enacted by a Neighborhood, the Neighborhood's restrictions
will control. Notwithstanding the foregoing provisions of this paragraph and except as permitted
under the Master Declaration, so long as Declarant owns any Existing Property or Additional
Property, no Person shall record any additional covenants, conditions or restrictions affecting any
portion of the Community without Declarant's written consent, it being acknowledged that the
foregoing Declarant consent shall be of a more general nature than the consent required pursuant
to Section 6.4(a) hereof. Any instrument recorded in violation of the foregoing sentence is void
and of no force and effect.

the obligation set forth in the foregoing sentence. Such defense costs shall include, but not
be limited to, attorney's fees and costs.
(b) Residential and Related Uses. The Community shall be used only in compliance
with applicable zoning, and then only for residential, recreational and related purposes. Related

3.1(d) below. In addition, the Association or Declarant may permit limited business activity
within the confines of a Dwelling Unit that does not detract from the Community's residential
and recreational character, provided the same complies with applicable zoning. Supplemental
Declarations or any other Recorded covenants may impose stricter standards than those contained
in this Article, or, in accordance with Section 6.4(a) hereof, Supplemental Declarations or any
other Recorded covenants may impose different standards from those contained in this Article,
and the Association shall have standing and the power to enforce such standards.

any Recreational Facilities, including without limitation, club meetings, classes, seminars, social
gatherings, lessons and other events and programs thereon.

sanctioned for any violation.
(i) Subdivision of a Lot and Time-Sharing. Lots may not be subdivided or their
boundary lines changed except in accordance with all applicable laws and with the Bond's prior
written approval; provided, however, Declarant, in its sole discretion, may subdivide, change the
boundary line of and replat any Lot(s) it owns, and, for so long as Declarant owns any portion of
the Community, Declarant may convert Lots into Common Area or Common Area to Lots at any
time prior to the transfer of title to such property to third parties or to the Association.

the Lot rotates among members of the program on a fixed or floating time schedule over a period
of years is prohibited, except by Declarant, while Declarant owns any property within the
Community.

any Lot, Parcel or other property which shall induce, breed or harbor infectious diseases or
noxious insects.

other than Declarant or a Person acting on behalf of Declarant unless the same shall be contained
in conduits or cables installed and maintained underground or concealed in, under or on buildings
or other structures approved by the Architectural Review Committee. No provision of this
Declaration shall be deemed to forbid the erection of temporary power or telephone structures for
emergency purposes or incident to the construction of buildings or structures approved by the
Architectural Review Committee. Notwithstanding the foregoing, utility meters and related
panels and similar equipment may be placed on outside building walls exposed to view from a
street in order to comply with any requirements, regulations, orders, conditions or specifications

3.4 Rule-Making Authority.
(a) The Board may change (i.e., modify, cancel, limit, create exceptions to or
expand) the Use Restrictions from time to time. The exercise of this authority shall be subject to
the Board's obligations as set forth in the By-laws and Articles and to the need to make as few
changes to the Use Restrictions as possible to meet the Board's objectives and still fulfill the
reasonable expectations of the Members. The Board shall provide notice to all Owners of any
proposed change to the Use Restrictions pursuant to the Association's then-current
communication policy at least five (5) business days before the Board meeting at which such
changes will be considered. Members shall have a reasonable opportunity to be heard on the
proposed change at such Board meeting.
If endorsed by the Board, the proposed change shall be approved unless it is rejected by a
majority vote of the Members. The Board is not obligated to call a meeting to reconsider any
rejection of a change unless it receives a petition to do so that meets the requirements for special
meetings set forth in the By-Laws. If the Board receives such a petition before the effective date
of the Board's action under this Subsection, the proposed change shall not become effective until
after the second meeting is held, and then subject to the outcome of such meeting.
(b) Alternatively, the Members, representing a majority of the votes in the
Association, at an Association meeting duly called for such purpose, may vote to change the Use
Restrictions then in effect. During the Declarant Control Period, any such change shall require
the approval of Declarant.
(c) Before any Use Restriction change can become effective, the Board shall provide
to each Owner, free of charge, a copy of the new or changed Use Restriction. The change shall
not become effective until at least thirty (30) days following the date of such mailing to all
Owners. Each Owner shall be bound regardless of whether the mailing is actually received. The
Association shall provide, free of charge, a copy of the Use Restrictions then in effect to any
Member, Tenant or Mortgagee requesting the same.
(d) At least once every two (2) years after the Declarant Control Period ends, the
Board shall review and evaluate the then-current Use Restrictions for continued viability or
necessity within the Community.
(e) No action taken under this Article shall have the effect of modifying, repeating or
expanding the Design Guidelines or any provision of this Declaration other than the Use
Restrictions. In the event of a conflict between the Design Guidelines and the Use Restrictions,
the Design Guidelines shall control.
(f) Notice under this Section may be sent to each Owner by any manner permitted
under the Association's then-current communication policy and North Carolina law, including, if
so permitted: (i) U.S. Mail, (ii) electronic communication (i.e., "fax" or "e-mail") or (iii)
publication in the community newsletter delivered or mailed to each Owner, provided such action
is clearly identified under a separate newsletter headline.
3.5 Protection of Members and Residents.
Except as may be set forth in this Declaration (either initially or by amendment) or in the
Use Restrictions, the Association's actions with respect to Use Restrictions and rules must
comply with the following:
RALEIGH 345594.1 23
DEED BOOK 3507 PAGE 193
amendments to this Declaration adopted in accordance with Article XXI hereof.
Article IV Architecture and Landscaping
4.1 General.
No structure or thing shall be placed, erected or installed upon any Lot, and no
Improvements or other work (including staking, clearing, excavation, grading and other site
work, exterior alterations or planting or removal of landscaping) shall take place within
Summerwind Plantation, except in compliance with this Article and the Design Guidelines. Each
Dwelling Unit shall be designed by and built in accordance with the plans and specifications of a
licensed architect unless Declarant or its designee, in its sole discretion, otherwise approves.
Any Owner may remodel, paint or redecorate the interior of an Improvement (including a
Dwelling Unit) on his or her Lot without approval. However, modifications to the interior of
screened porches, patios and any other portions of a Lot visible from outside an Improvement
shall be subject to approval as set forth in the Design Guidelines.
This Article shall not apply to Declarant's activities or to the Association's activities
during the Declarant Control Period.
4.2 Architectural Review.
(a) By Declarant; New Construction. Declarant shall have exclusive authority under
this Declaration to administer and enforce architectural controls and to review and act upon all
applications for original construction within the Community. This right shall continue until one
hundred percent (100%) of the Lots have been conveyed to Members, other than Declarant or the
Association, and each such Lot contains a finished Dwelling Unit, unless Declarant earlier
terminates its rights in a Recorded instrument. In reviewing and acting upon any request for
approval, Declarant or its designee acts solely in Declarant's interest and owes no duty to any
other Person.
Declarant may, in its discretion, designate one or more Persons or an outside
management company to act on its behalf from time to time in reviewing applications.
From time to time, Declarant may, but shall not be obligated to, delegate or assign all or
any portion of its rights under this Article to any other Person or committee, including the
Architectural Review Committee. Any such delegation shall be in writing, specifying the
delegated responsibilities, and shall be subject to (i) Declarant's right to revoke such delegation at
any time and reassume its prior jurisdiction, and (ii) Declarant's right to veto any decision which
it determines, in its discretion, to be inappropriate or inadvisable for any reason. So long as
Declarant has any rights under this Article, the jurisdiction of other entities shall be limited to
such matters as Declarant specifically delegates.
(b) Architectural Review Committee; Modifications. During the Declarant Control
Period, Declarant shall have exclusive authority to administer and enforce architectural controls
and to review and act upon all applications for modifications to Improvements constructed within
the Community. Declarant is to maintain Records of all approvals and denials and to turn them
over to the Association at the end of the Declarant Control Period. Prior to termination of
Declarant's rights under Section 4.2(a) hereof or to further a delegation if requested by Declarant,
the Board shall establish the ARC, which shall consist of at least three (3) Persons. Members of
RALEIGH 345594.1 25
DEED BOOK 3507 PAGE 195
construction or modification has commenced in compliance with applicable laws and ordinances.
Subject to the Community-Wide Standard, there shall be no limitation on the scope of
amendments to the Design Guidelines, and such amendments may remove requirements
previously imposed or otherwise make the Design Guidelines less restrictive.
The Reviewer shall make the Design Guidelines available to Owners who seek to engage
in construction within Summerwind Plantation.
(b) Custom Lot Guidelines. Declarant may prepare Custom Lot Guidelines, if
Declarant elects to sell custom lots within the Community. It may follow the same procedures as
apply to the Design Guidelines, or it may establish new procedures.
(c) Procedures. Except as otherwise specifically provided in the Design Guidelines,
no construction activities or other activities described in Section 4.1 hereof shall commence on
any portion of Summerwind Plantation until an application has been submitted to and approved
by the Reviewer. The application shall (i) be in the form Reviewer requires, (ii) include plans and
specifications and other information required under the Design Guidelines and (iii) be approved
in writing, at the time of submission, by the Owners of the Lots adjacent to the applicant's Lot.
Plans and specifications shall show, as applicable site layout, structural design, exterior
elevations, exterior materials and colors, landscaping, drainage, exterior lighting, irrigation and
other features of the proposed construction. The Design Guidelines and the Reviewer may require
additional information as reasonably necessary to consider any application.
In reviewing each submission, the Reviewer may consider any factors it deems relevant,
including, without limitation, harmony of external design with surrounding structures and
environment. Decisions may be based on purely aesthetic considerations. Each Owner
acknowledges that aesthetic determinations are purely subjective, and opinions may vary as to the
desirability and/or attractiveness of particular Improvements. Subject to Declarant's veto right,
the Reviewer shall have the sole discretion to make final, conclusive and binding determinations
on matters of aesthetic judgment, and such determinations shall only be subject to review or
appeal to the Board on the issue of good faith and in accordance with the required procedures.
The Reviewer shall make a determination on each application within 45 days after receipt
of a completed application and all information it requires. The Reviewer may permit or require
that an application be submitted or considered in stages, in which case, a final decision shall not
be required until after the final, required submission stage. The Reviewer may (i) approve the
application, with or without conditions; (ii) approve a portion of the application and disapprove
other portions, with or without conditions or (iii) disapprove the application.
The Reviewer shall notify the applicant in writing of a final determination on any
application within five (5) days after such determination is made. In the case of disapproval, the
Reviewer may, but shall not be obligated to, specify the reasons for any objections and/or offer
suggestions for curing any objections.
If the Reviewer fails to respond by the deadlines set forth above, approval shall be
deemed given. However, no approval, whether expressly granted or deemed granted, shall be
inconsistent with the Design Guidelines unless a written variance has been granted pursuant to
Section 45 hereof.
RALEIGH 345594.1 27
01?EIJ BQQK :3SU-/ PAGE 197
variance may be issued without Declarant's written consent for so long as Declarant owns any
portion of the Community or has the unilateral right to annex Additional Property.
4.6 Limitation of Liability.
(a) The standards and procedures established by this Article are intended as a
mechanism for maintaining and enhancing the overall aesthetics of Summerwind Plantation; they
do not create any duty to any Person. Review and approval of any application pursuant to this
Article may be based on aesthetic considerations only. The Reviewer shall not
bear any responsibility for ensuring the structural integrity or soundness of approved construction
or modifications, for ensuring compliance with building codes and other governmental
requirements or for ensuring that every Dwelling Unit is of comparable quality, value or size, of
similar design or aesthetically pleasing or otherwise acceptable to other Owners provided the
Community-Wide Standards shall serve as a guide in the review process.
(b) Declarant, the Association, its officers, the Board, the ARC, the Association's
management agent, any committee or any member of any of the foregoing shall not be held liable
for matters related to its decisions including, but not limited to, soil conditions, drainage or other
general site work; any defects in plans revised or approved hereunder, any loss or damage arising
out of the action, inaction, integrity, financial condition, or quality of work of any contractor or its
subcontractors, employees or agents, whether or not Declarant has approved or featured such
contractor as a builder in the Community; or any injury, damages or loss arising out of the
manner or quality or other circumstances of approved construction on or modifications to any
Lot. In all matters, the Board, the ARC, the members of each and the Association officers, shall
be defended and indemnified by the Association as provided in Section 7.7 hereof.
4.7 Certificate of Compliance.
Declarant or any Owner may request in writing that the Association issue a certificate of
architectural compliance certifying either that there are no known violations of this Article or the
Design Guidelines as to the Owner's Lot or specifying such violations. The Association may
charge a reasonable administrative fee in connection with responding to such a request. The
Association shall either issue such a certificate within 45 days after receipt of the written request
therefor, or a certificate specifying no violations shall be deemed to have been issued, Issuance of
such a certificate shall estop the Association from taking enforcement action against an Owner for
any condition known to the Association on the date of the certificate and not specified therein.
Article V Landscaping, Home Maintenance and Repair
5.1 [Intentionally Omitte
5.2 Maintenance of Lots.
Each Owner shall maintain its Lot, including the Dwelling Unit and all other
Improvements situated on or in the Lot, in a manner consistent with the Governing Documents,
the Master Declaration, the Community-Wide Standard and any other applicable covenants,
unless such maintenance responsibility is otherwise assumed by or assigned to the Association
pursuant to any Supplemental Declaration or additional covenants applicable to such Lot.
The initial maintenance obligations for Owners, specified by Dwelling Unit type, are set
forth in Exhibit E. Exhibit E constitutes only the initial division of maintenance responsibilities
RALEIGH 345594.1 29
DEED BOOK 3507 PAGE 199
within the Neighborhood and for clearing and maintaining the Lots in the event the structures are
not rebuilt or reconstructed, any of which may be more strict than the standards set forth herein;
provided, however, if written consent to the Neighborhood covenants is obtained in accordance
with Section 6.4(a) hereof, then provisions of the Neighborhood covenants may differ from the
standards set forth herein.
C. COMMUNITY GOVERNANCE AND ADMINISTRATION
This Declaration establishes the Association as the mechanism by which each Owner is
able to participate in the governance and administration of Summerwind Plantation. While many
powers and responsibilities are vested in the Association's Board of Directors in order to
facilitate day-to-day management and operation, some decisions are considered of such
importance that they are reserved for the Association's Membership - the Lot Owners.
Article VI The Association and its Members
6.1 Function of Association.
The Association is responsible for the management, maintenance, operation and control
of the Common Area, subject to any covenants, easements or restrictions set forth in the deed or
other instrument transferring the property to the Association. The Association may choose to
oversee the administration of certain social programs for the benefit of the Owners and, in so
doing, may hire a lifestyle director and additional staff for the administration of such programs,
either as employees or as independent contractors. The Association also has primary
responsibility for enforcing the Governing Documents. The Association shall perform its
functions in accordance with the Governing Documents and North Carolina law.
6.2 Membership
Every Owner is a Member of the Association, but there shall be no more than one
Membership per Lot. If a Lot is owned by more than one Person, all co-Owners shall share the
privileges of Membership, subject to the By-Laws, reasonable Board Regulations and Rules and
the voting restrictions described in Section 6.3(c) hereof. Co-Owners are jointly and severally
obligated to perform the responsibilities of an Owner. The Membership rights of an Owner that
is not an individual may be exercised by any officer, director, partner, manager, member or
trustee, or by an individual the Owner designates from time to time in a written instrument
provided to the Association's Secretary.
6.3 Voting.
(a) Voting Matters. During the Declarant Control Period or during such time as
Declarant owns any of the Community or has a unilateral right to annex Additional Property
pursuant to Section 11.1 hereof, the only matters subject to a vote of all the Members in the
Community or by one or more Neighborhoods are those which the Declarant wishes to put to a
Community-Wide or Neighborhood vote, as applicable. The foregoing sentence shall not relieve
the Declarant or the Association, as the case may be, of the obligation to provide budget
summaries to the Owners following adoption of a proposed budget and to hold a meeting for the
purpose of obtaining a ratification vote on the proposed budget, as required by the Act.
(b) Members. Members shall have one (1) equal vote for each Lot in which they hold the
interest required for Membership under Section 6.2 hereof, except that there shall be only one (1)
RALEIGH 345594.1 31
DEED BOOK 3507 PAGE 201
Neighborhood meetings for a defined term, as established by the Board and shall be responsible
for communication between the Owners in the Neighborhood and the Board. Neighborhood
Representatives also shall attend Neighborhood Representative meetings when requested by the
Board. In addition, each Neighborhood shall elect an alternate Neighborhood Representative
who shall act in the absence of the Neighborhood Representative. The Neighborhood
Representative and alternate Neighborhood Representative shall be Owners in good standing of a
Lot in the Neighborhood they represent.
If applicable, Declarant shall appoint the initial Neighborhood Representatives no later
than at such time as twenty-five percent (25%) of the Lots anticipated for the Community under
the Summerwind Plantation Plan have been conveyed to Members; provided, a Neighborhood
Representative need not be appointed for any particular Neighborhood prior to the time that
twenty-five percent (25%) of the Lots anticipated for such Neighborhood under the Summerwind
Plantation Plan have been conveyed to Members. After the term expires for Declarant's initial
appointment for a Neighborhood, the Board shall call for an election of a Neighborhood
Representative and an alternate from such Neighborhood on an annual basis, either by written
ballots cast by mail, computer or at a meeting of the Members within the Neighborhood, as the
Board determines. Candidates for election as Neighborhood Representatives may be nominated
by the Board, a nominating committee which the Board may appoint or from the floor at any
meeting at which such election is to be held.
The presence, in person or by proxy, or the filing of ballots by Members representing at
least twenty-five percent (25%) of the total votes attributable to Lots in the Neighborhood shall
constitute a quorum at any Neighborhood meeting or election. In the event of a failure to obtain
a quorum or vacancy in such positions for any Neighborhood, the Board may appoint a
Neighborhood Representative or alternate Neighborhood Representative to represent the
Neighborhood until a successor is elected.
For any Neighborhood election, each Member shall have one (1) equal vote for each Lot
the Member owns in the Neighborhood. The candidate who receives the greatest number of votes
shall be elected as the Neighborhood Representative, and the candidate receiving the next greatest
number of votes shall be elected as the alternate Neighborhood Representative. The
Neighborhood Representative and the alternate Neighborhood Representative shall serve until
their successors are elected.
Any Neighborhood Representative or Alternate Neighborhood Representative may be
removed, with or without cause, upon the vote or written petition of Owners of a majority of the
Lots owned by Members in the applicable Neighborhood.
Article VII Association Powers and Responsibilities
7.1 Acceptance and Control of Association Property.
(a) The Association, through action of its Board, may acquire, hold, lease (as
landlord or tenant), operate and dispose of tangible and intangible personal property and real
property. Contracts for terms in excess of one (1) year shall require a majority vote of the
Members. The Association may enter into leases, licenses or operating agreements for portions
of the Common Area, for payment or no payment as the Board deems appropriate, to permit use
of portions of the Common Area by community organizations and by other third parties for the
general benefit of or as a convenience to Owners and other residents of Summerwind Plantation.
A conveyance or mortgage of the Common Area requires eighty percent (80%) approval of the
RALEIGH 345594.1 33
DEED BOOK 3507 PAGE 203
The Association shall maintain the facilities and equipment within the Common Area in
continuous operation, except for any periods necessary to perform required maintenance or
repairs, as determined by the Board in its sole discretion, unless and until Members representing
seventy-five percent (75%) of the Member votes in the Association, and Declarant, if during the
Declarant Control Period, agree in writing to discontinue such operation.
Except as provided above, the Common Area shall not be reduced or increased except
with Declarant's prior written approval during the Declarant Control Period, or for so as long as
Declarant owns any part of the Community or has the unilateral right to annex Additional
Property into the Community pursuant to Section 11.1 hereof.
The costs incurred by the Association in connection with the maintenance, repair and
replacement of the Common Area, excluding Limited Common Areas, shall be a Common
Expense; provided, the Association may, but shall not be obligated to, seek reimbursement from
the owner(s) of, or other Persons responsible for, certain portions of the Common Area pursuant
to this Declaration, a Supplemental Declaration or other Recorded covenants or agreements.
Maintenance, repair and replacement of Limited Common Areas shall be a Neighborhood
Expense assessed against the Lots within the benefited Neighborhood(s).
7.3 Insurance.
(a) Required Coverages. The Association, acting through the Board or an agent duly
authorized by the Board, shall obtain and continue in effect the following types of insurance, if
reasonably available, or if not, the most nearly equivalent coverages as are reasonably available:
(i) Blanket property insurance covering "all risks of direct physical loss" on
a "special causes of loss form" basis (or comparable coverage by whatever name
denominated) for all insurable improvements on the Common Area and within
other portions of the Common Area to the extent that the Association has
assumed responsibility in the event of a casualty, regardless of ownership. If
such coverage is not generally available at reasonable cost, then "broad causes of
loss form" (specified perils) coverage may be substituted. All Association
property insurance policies shall have policy limits sufficient to cover the full
replacement cost of the insured improvements under current building ordinances
and codes;
(ii) Commercial general liability insurance on the Common Area, insuring
the Association and its Members for damage or injury caused by the negligence
of the Association or any of its Members, employees or agents while acting on
behalf of the Association, and if generally available at a reasonable cost, such
coverage (including primary and any umbrella coverage) shall have a limit of at
least $5,000,000.00 per occurrence and in the aggregate with respect to bodily
injury, personal injury, and property damage;
(iii) With respect to any contractors working on the Common Area or any
third parties holding events on the Common Area, all such individuals shall be
required to carry sufficient similar commercial general liability insurance with
minimum limits of $1,000,000.00 combined single limit per occurrence and
$1,000,000.00 general aggregate limit, and shall be endorsed to include
Summerwind Plantation, LLC, and its respective managers, members, employees
RALEIGH 345594.1 35
DEED BOOK 3507 PAGE 205
certificate of insurance to be furnished to the Association and, upon request, to each Member who
is insured thereunder. Declarant reserves the right to satisfy its requirements to obtain and
maintain insurance under Declarant's blanket policy, provided that the cost to replace the
insurance when such coverage terminates shall be disclosed to the Members as a footnote to the
Budget.
Insurance policies may contain a reasonable deductible which shall not be subtracted
from the face amount of such policies in determining whether the policy limits satisfy the
requirements of Section 73(a) hereof In any event, the total amount of insurance after application
of deductibles shall be not less than eighty percent (80%), or the then-current percentage required
by the Act, of replacement costs, exclusive of land, excavations, and foundations, at each renewal
date. In the event of an insured loss, the deductible shall be treated as a Common Expense or a
Neighborhood Expense, as applicable, in the same manner as the premiums for the applicable
insurance coverage are treated. However, if the Board reasonably determines, after notice and an
opportunity to be heard in accordance with the By-Laws, that the loss is the result of the
negligence or willful misconduct of one or more Owners, their guests, invitees or tenants, then the
Board may assess the full amount of such deductible against such Owner(s) and their Lots as a
Benefited Assessment.
All insurance coverage obtained by the Board shall:
(i) be written with a company authorized and licensed to do business in
North Carolina;
(ii) be written in the name of the Association as trustee for the benefit of the
benefited parties specified in this subsection (b)(ii). Policies covering the
Common Areas shall be for the benefit of the Association and its Members.
Policies secured on behalf of a Neighborhood shall be for the benefit of the
Owners within the Neighborhood and their Mortgagees, as their interests may
appear;
(iii) not be brought into contribution with insurance purchased by
individual Owners, their Mortgagees, or any occupants of a Lot;
(iv) contain an inflation guard endorsement;
(v) include an agreed amount endorsement, if the policy contains a co-
insurance clause;
(vi) provide that each Owner is an insured person under the policy with
respect to liability arising out of such Owner's interest in the Common Area as a
Member in the Association (provided this provision shall not be construed as
giving an Owner any interest in the Common Area other than that of a Member);
(vii) Unless the Board waives the requirement of this Subsection (b)(vii), it
must include an endorsement precluding cancellation, invalidation. suspension or
non-renewal by the insurer on account of any one or more individual Owners or
on account of any curable defect or violation without prior written demand to the
Association to cure the defect or violation and allowance of a reasonable time to
cure; and
RALEIGH 345594.1 37
DEED BOOK JbU'/ PAGE 207
The Association shall retain any insurance proceeds remaining after paying the costs of
repair or reconstruction, or after an agreed upon settlement, for the benefit of the Members or the
Owners of Lots within the insured Neighborhood, as appropriate, and place such finds in a capital
improvements account.
If insurance proceeds are insufficient to cover the costs of repair or reconstruction, the
Board may, without a vote of the Members, levy Special Assessments to cover the shortfall
against those Owners responsible for the applicable insurance premiums.
7.4 Compliance and Enforcement
(a) The Board may impose sanctions for Governing Documents violations, which
sanctions include those listed below and any others specifically described in the Governing
Documents. The Board may establish a range of penalties for different violations, with violations
of this Declaration, unsafe conduct and harassment or intentionally malicious conduct treated
more severely than other violations.
The following sanctions require prior notice and an opportunity for a hearing in
accordance with the By-Laws (provided only a single notice and hearing is required for
continuing violations) and the Act:
W imposing reasonable monetary fines, not to exceed one hundred dollars ($100.00)
per violation (or per day, after the decision to impose a fine in the case of a continuing
violation) or the highest amount allowed by the Act, if different, which shall constitute a
lien upon the violator's Lot enforceable in the same manner in which Assessments may
be enforced, subject to any limitations on enforcement imposed by the Act. Fines may be
imposed within a graduated range. There is no limit on the aggregate amount of any fine
for a continuing violation;
(ii) suspending an Owner's right to vote;
(iii) suspending any Person's right to use Common Area amenities;
provided, however, nothing shall authorize the Board to impair an Owner's or occupant's
access to his or her Lot;
(iv) suspending any services of the Association;
(v) exercising self-help or taking action to abate any violation of the Governing
Documents occurring on a Lot in a non-emergency situation; and
(vi) levying Benefited Assessments to cover costs incurred by the
Association to bring a Lot into compliance with the Governing Documents.
(b) In addition, the Board, or its designees, may take the following enforcement
actions to ensure compliance with the Governing Documents without the necessity of following
the procedures set forth in the By-Laws:
(i) exercising self-help in any emergency situation (specifically
including, but not limited to, (1) towing vehicles that are in violation of parking
rules and regulations and (2) any action necessary to protect and safeguard
RALEIGH 345594.1 39
UZZU BUUiC snu i raciE 1U9
(ii) the covenant, restriction or rule being enforced is, or is likely to be,
construed as inconsistent with applicable law;
(iii) although a technical violation may exist or may have occurred,
it is not of such a material nature as to be objectionable to a reasonable person or
to justify expending the Association's resources; or
(iv) that it is not in the Association's best interests, based upon
hardship, expense or other reasonable criteria, to pursue enforcement.
Such a decision shall not be construed a waiver of the Association's right to enforce such
provision at a later time or preclude the Association from enforcing any other covenant,
restriction or rule.
The Association, by contract or other agreement, may, but shall not be required to,
enforce applicable town ordinances, and Johnston County may enforce its ordinances within
Summerwind Plantation.
7.5 Enforcement of Design Guidelines.
(a) Any construction, alteration or other work performed in violation of the Design
Guidelines shall be deemed to be nonconforming. Upon written request from the Association or

RALEIGH 345594.1 41
DEED BOOK 3507 PAGE 211
This right to indemnification shall not be exclusive of any other rights to which any

same shall be a Common Expense.
7.8 Safety and Security.
Each Owner and occupant of a Lot, and their respective guests and invitees, are
responsible for their own personal safety and the security of their property in Summerwind
Plantation. The Association may, but shall not be obligated to, maintain or support certain
activities within the Community designed to enhance the level of safety or security which each
person provides for himself and his property. Neither the Association nor Declarant shall in any
way be considered insurers or guarantors of safety or security within the Community, nor shall
either be held liable for any loss or damage by reason of failure to provide adequate security or
ineffectiveness of security measures undertaken.
No representation or warranty is made that any systems or measures, including any
mechanism or system for limiting access to the Community, cannot be compromised or
circumvented, nor that any such systems or security measures undertaken will in all cases prevent
loss or provide the detection or protection for which the system is designed or intended. Each
Owner acknowledges, understands and shall he responsible for informing its tenants and all
occupants of its Lot that the Association, its Board and committees, and Declarant are not
insurers or guarantors of security or safety and that each Person within Summerwind Plantation
assumes all risks of personal injury and loss or damage to property, including Lots and the
contents of Lots, resulting from acts of third parties.
7.9 Security or Access Gates.
Security or Access Gates may be constructed within or adjacent to Summerwind
Plantation in order to limit access and to provide more privacy for Owners and Occupants. Each
Owner and Occupant, and their families, guests and invitees, acknowledge that any such Security
or Access Gate may restrict or delay entry into, or access within Summerwind Plantation by
police, fire department, ambulances and other emergency vehicles or personnel. Each Owner and
Occupant and their families, guests and invitees agree to assume the risk that any such Security or
Access Gate will restrict or delay entry into, or access within Summerwind Plantation by police,
fire department, ambulances or other emergency vehicles or personnel. Neither Declarant, the
Association nor any director, officer, agent or employee of Declarant of the Association shall be
liable to any Owner or Occupant or their families, guests or invitees for any claims or damages
resulting directly or indirectly, from the construction, existence or maintenance of any such
Security or Access Gate.

express, with respect to the use of any property subject to this Declaration or any part of the
Additional Property.

Members, and thereafter, pursuant to action of the Members taken at a duly called meeting of the
Members, the Board shall have the power and right to change the use of portions of the Common
Area and Limited Common Area. Any such change shall be pursuant to Board resolution stating
that: (a) the present use or service is no longer in the best interest of the Owners, (b) the new use
is for the benefit of the Owners, (c) the new use is consistent with any deed restrictions and
zoning regulations restricting or limiting the use of the Common Area or Limited Common Area,

and (e) in the case of Limited Common Area serving one or more Neighborhoods, the change has
been approved by the Neighborhood Committee(s), if any, that administer such Limited Common
Area.
Notwithstanding the above provisions of this subsection, if, after the Declarant Control
Period, the Board adopts a resolution which states that the change in use will not have an adverse
effect on the Association and the Owners, the Board may give notice of the change to all
Owners. The notice shall give the Owners a sight to object within thirty (30) days of the notice.
If less than ten percent (10%) of the Members who will be affected by the change submit written
objections, the change shall be deemed approved, and a meeting shall not be necessary.
7.14 View Impairment.
Neither Declarant nor the Association guarantee or represent that any view over and
across the Lots, or any Common Area or open space within the Community will be preserved
without impairment, and neither party shall be obligated to relocate, prune or thin trees or other
landscaping except to maintain the Community-Wide Standard or as otherwise required under a
separate covenant or agreement The Association and Declarant (with respect to the Common
Area) have the right to add trees, walls, fences, berms, homes or other structures, signs, lighting,
water features and other landscaping from time to time subject to applicable law. Any express or
implied easements for view purposes or for the passage of light and air are hereby expressly

Association and the Members. The Association may contribute or receive money, real property
(including Common Area), personal property or services to or from any such entity. Any such

remedies to enforce these rules and regulations for the purposes promulgated thereunder may
include either the temporary or permanent suspension of all lot owner's rights to own and operate

Plantation community, the Board has the authority to either temporarily or permanently prohibit
the use and operation of such golf cart by any offending owner, or their tenants, guests,
employees, family members or invitees based on the Board's determination after appropriate
notice and hearing.
Article VIII Telecommunity
An important aspect of the Association's mission is to perpetuate a sense of community
life and spirit within Summerwind Plantation. To promote this goal, the Association may provide
technology, activities, services, educational opportunities, entertainment, social events,
healthcare information and other programs for the Community. By providing these diverse
components, the Association endeavors to establish community building and networking
opportunities among all members of the Community.
In order to encourage awareness of and participation in, the activities, programs,
opportunities, events and services provided by or through the Association, a telecommunity
system may be developed to provide a communication resource that connects all members of the
Community.
8.1 Community Intranet System.
A community intranet system, which would be maintained by the Association, may be
established by the Declarant (during the Declarant Control Period) or if thereafter by the
Association. The Board shall have discretion and authority in determining and selecting an

companies licensed to provide telecommunications and cable television service in the vicinity of
Summerwind Plantation, and to charge individual users a reasonable fee not to exceed the
maximum allowable charge for such service, as from time to time is defined by the laws, rules
and regulations of the relevant government authority, if applicable.
Declarant may require that the Association enter into a bulk rate service agreement for
the provision of Community Systems to all Lots as a Common Expense. If particular services or
benefits are provided to particular Owners or Lots at their request, the benefited Owner(s) shall
pay the service provider directly for such services, or the Association may assess the costs as a
Neighborhood Assessment or Benefited Assessment, as appropriate.
8.6 Notices and Disclaimers as to Community Systems
In recognition of the fact that interruptions in cable television and other Community
Systems services will occur from time to time, neither Declarant nor any of Declarant's
successors or assigns shall in any manner be liable for, and no Community System user shall be
entitled to refund, rebate, discount or offset in applicable fees, for any interruption in Community
Systems services, regardless of whether or not such interruption is caused by reasons within the
service provider's control.
8.7 Disclaimer and Limitation of Liability.
The Association shall not be liable for any loss, damage or injury resulting from (a) any
virus or contamination of any data, computer or computer system arising from access to the
Community Systems; (b) any delays, interruptions or inconveniences in accessing or using any
functions of the Community Systems or inability to access or download information, software or
other materials through the Community Systems; (c) the quality, validity, completeness of or any
inaccuracies, errors or omissions in, any information, software or other materials accessible
through the Community Systems. The Association does not endorse and makes no
representations or warranties regarding the quality, safety, suitability or usefulness of any

security of any web site is not guaranteed; therefore, by placing an entry on the web site, you
understand the potential security risks involved and acknowledge that Declarant and Association

to:
1. Satisfy any law, regulation or authorized governmental request;
RALEIGH 345594.1 49
DEED BOOK 3507 PAGE 219
Lots and the amount to be generated through the levy of Assessments against the Lots in such
Neighborhood.
The Board shall make available copies of each Neighborhood's budget and shall send
notice of the amount of the Neighborhood Assessment with a summary of the Neighborhood
budget for the coming year to each Owner in the Neighborhood at least thirty (30) days before the
fiscal year begins. Except as required under Section 9.9 hereof, Neighborhood budgets shall not
be subject to Owner approval, and there shall be no obligation to call a meeting to consider
Neighborhood budgets.
If the proposed budget for any Neighborhood is disapproved under Section 9.9 hereof or
if the Board fails for any reason to determine a Neighborhood's budget for any year, then until
such time as a budget is determined, the Neighborhood budget in effect for the year before shall
continue for the current year.
The Board may revise the budget for any Neighborhood and the amount of any
Neighborhood Assessment from time to time during the year, subject to the notice requirements
and the right of the Owners of Lots in the affected Neighborhood to disapprove the revised
budget as set forth above.
All amounts the Association collects as Neighborhood Assessments shall be held in trust
for and expended solely for the benefit of the Neighborhood for which they were collected. Such
amounts shall be accounted for separately from the Association's general funds.
9.3 Budgeting for Reserves.
Within six (6) months following conveyance of the Common Areas to the Association,
the Board shall obtain a Reserve Study and establish or verify that the Budget includes
appropriate reserves. The Budget shall include expenses associated with Common Area and each
Neighborhood for which the Association maintains capital items as a Neighborhood Expense, if
any. The budget for Reserves shall take into account the number and nature of replaceable assets,
the expected life of each asset and the expected repair or replacement cost. The Board shall, in
the exercise of its business judgment, establish a plan to find Reserves at a level projected to
achieve 40-60% funding by the end of the Declarant Control Period; thereafter, the Board shall
review the budget for Reserves annually and when additional common areas are conveyed.
Amounts to be funded as reserves shall be reflected as such in the budget for Common Expenses
and the Neighborhood budgets, as appropriate.
The Board shall adopt a policy restricting the expenditure of any Reserves, including
policies designating the nature of assets for which Reserves may be expended. Such policies may
differ for general Association purposes and for each Neighborhood. During the Declarant
Control Period, neither the Association nor the Board shall adopt, modify, limit or expand such
policies without Declarant's prior written consent.
The Board may enter into agreements with Declarant regarding the timing and extent of
Declarant contributions, on negotiated terms, under which Declarant may provide financial
assurances in lieu of cash.
9.4 Special Assessments.
In addition to other authorized Assessments, the Association may levy Special
RALEIGH 345594.1 51
DEED BOOK 3507 PAGE 221
paid annually, semi-annually or in quarterly or monthly installments. Until the Board otherwise
provides, the annual Base Assessment and any Neighborhood Assessment shall be due and
payable in advance on the first day of each fiscal year. If any Owner is delinquent in paying any
Assessments or other charges levied on its Lot, the Board may require the outstanding balance on
all Assessments to be paid in full immediately.
9.7 Obligation for Assessments,
(a) Personal Obligation. Each Owner, by accepting a deed for any Lot, covenants
and agrees to timely pay all Assessments authorized in the Governing Documents. All
Assessments, together with interest (computed from its due date at a rate of eighteen percent
(18%) per annum or such higher rate as the Board may establish, in compliance with the Act and
otherwise subject to the limitations of North Carolina law), late charges as determined by Board
resolution, costs and reasonable attorneys' fees, shall be the personal obligation of each Owner
and a lien upon each Lot until paid in full. Upon a transfer of title to a Lot, the grantee of title
shall be jointly and severally liable for any Assessments and other charges due at the time of
conveyance.
The Board's failure to establish or obtain Member approval of Assessment amounts or
rates, if required hereunder, or the Board's failure to deliver or mail to each Owner an
Assessment notice shall not be deemed a waiver, modification or a release of any Owner from the
obligation to pay Assessments. In such event, each Owner shall continue to pay Base
Assessments and Neighborhood Assessments on the same basis as during the last fiscal year for
which an Assessment was made, if any, until a new Assessment is levied, at which time the
Association may retroactively assess any shortfalls in collections,
No Owner is exempt from liability for Assessments by non-use of Common Area,
abandonment of his or her Lot or any other means. The obligation to pay Assessments is a
separate and independent covenant for which each Owner is jointly and severally liable. No
diminution or abatement of Assessments or set-off shall be claimed or allowed for any alleged
failure of the Association or Board to take some action or perform some function required of it, or
for inconvenience or discomfort arising from the making of repairs or improvements, or from any
other action taken by the Association or Board.
Common Expense caused by negligence or misconduct of an Owner, Tenant or Occupant
may be assessed exclusively against the Owner or Occupant's Lot.
Within ten (10) business days of receiving a written request from an Owner, Mortgagee
or other person designated by the Owner, the Association shall fumish to the requesting party or
other Person designated in the written request a certificate in writing signed by an Association
officer setting forth the amount of any unpaid Assessments against the applicable Lot. Such
certificate shall be conclusive evidence of payment or non-payment. The Association may
require the advance payment of a reasonable processing fee for the issuance of such a certificate.
(b) Declarant's Obligation.
(i) During the Declarant Control Period, Declarant shall not be obligated to pay
Assessments on its unsold Lots but, instead, shall be obligated to pay a subsidy based on
the "shortage" (i.e., operating deficit) for each fiscal year. A "shortage" shall exist if
Income and Revenues (each as defined below) for a particular fiscal year are less than
RALEIGH 3455941 53
DEED BOOK 3507 PAGE 223
charge of any Recorded first Mortgage (meaning any Recorded Mortgage with first priority over
other Mortgages) made in good faith and for value and (c) the lien of any assessments levied
pursuant to the Master Declaration. Such lien, when delinquent, may be enforced by suit,
judgment and judicial or non judicial foreclosure in a like manner as the foreclosure of a deed of
trust, pursuant to North Carolina General Statutes 45, Section 2A.
At a foreclosure sale, the Association may bid for the Lot and acquire, hold, lease,
mortgage and convey the Lot. The Association may sue for unpaid Assessments and other
charges without foreclosing or waiving its Assessment lien.
Sale or transfer of any Lot shall not affect the Assessment lien or relieve such Lot from
the lien for any subsequent Assessments. However, the sale or transfer of any Lot pursuant to
foreclosure by the first Mortgagee extinguishes the lien relating to any amounts due prior to the
Mortgagee's foreclosure. The purchaser of a foreclosed Lot shall not be personally liable for
Assessments on such Lot due prior to the foreclosure sale. Such unpaid Assessments shall be
deemed to be Common Expenses collectible from Owners of all Lots subject to Assessment under
Section 9.6 hereof, including such purchaser, its successors and assigns.
Notwithstanding the above, if a Lot is owned by the Association: (a) no right to vote shall
be exercised on its behalf, (b) no Assessment shall be levied on it and (c) each other Lot shall be
charged, in addition to its usual Assessment, its pro rata share of the Assessment that would have
been charged such Lot had it not been acquired by the Association.
9.9 Limitation on Increases of Assessments.
Notwithstanding any provision to the contrary, and except for Assessment increases
necessary for emergency situations, the Board may not impose a Base Assessment or
Neighborhood Assessment that is more than twenty percent (20%) greater than such Assessments
for the immediately preceding fiscal year without the approval of a majority of the Members
subject to the applicable Assessment. Approval may be indicated by vote or written consent.
An emergency situation is any one of the following:
(a) an extraordinary expense required by an order of a court;
(b) an extraordinary expense necessary to repair or maintain any portion of the
Community for which the Association is responsible where a threat to personal safety is
discovered; or
(c) an extraordinary expense necessary to repair or maintain any portion of the
Community for which the Association is responsible which could not reasonably have been
foreseen by the Board in preparing and distributing the pro forma budget pursuant to Section 9.1
hereof. However, prior to the imposition or collection of such an Assessment, the Board shall
pass a resolution containing written findings as to the necessity of the extraordinary expense
involved and why the expense was not or could not have been reasonably foreseen in the
budgeting process. Notice of such resolution shall be provided to the Members along with the
notice of such Assessment.
RALEIGH 345594.1 55
DEED BOOK 3507 PAGE 225
premiums included, and shall be due upon the closing of the Sale of the Lot. The Gross Selling
Price shall be the total cost to the purchaser of the Lot, excluding transfer taxes and title fees
imposed by Wake County.
(c) Purpose. New Member Fees allocated to the Association shall be used for
purposes which the Association Board deems beneficial to meet the general operating nets of the
Association. By way of example and not limitation, New Member Fees may be used to assist the
Association of one or more tax-exempt entities in funding operating and maintenance costs for
recreational facilities, common areas open space preservation and all other funding needs for
operating the Association.
(d) Duration. The term for the collection of the New Member Fee shall be the
duration of this Declaration for the portion payable to the Association and for a term of ten (10)
years from the date of Recording of this Declaration for the portion to be paid to Declarant.
(e) Exempt Transfers. Notwithstanding the above, no New Member Fee shall be
levied upon transfer of title to property:
(i) by or to Declarant;
(ii) by a co-owner to any Person who was a co-owner immediately prior to
such transfer;
(iii) to the Owner's estate, surviving spouse, or heirs at law upon
the death of the Owner
(iv) to an entity wholly owned by the grantor or to a family trust created by
the grantor for the direct benefit of the grantor and his or her spouse and/or heirs
at law; provided, upon any subsequent transfer of an ownership interest in such
entity, the New Member Fee shall become due; or
(v) to an institutional lender as security for the performance of an obligation
pursuant to a Mortgage.
9.13 Collection of Master Declaration Assessments
The Association has the authority to collect as due from Owners in the Community the
amount of any assessments coming due under the terms of the Master Declaration. Nothing in
the foregoing sentence shall be construed so as to limit or waive the Master Association's right
and authority to collect any assessments due under the Master Declaration. Any such amounts
collected by the Association pursuant to the Master Declaration shall be remitted promptly to the
Master Association and shall not at any time be considered as property of the Association.
Assessments due under the Master Declaration shall be allocated equally among all similarly
situated Lots. Notwithstanding the foregoing sentence, assessments due under the Master
Declaration charged to the Association shall be a line item in the Association budget to be
collected from Owners in the same manner as general assessments pursuant to this Article IX and
shall be paid to the Master Association or the Master Declarant, as the case may be. The
aforementioned assessment obligation shall be enforceable by the Master Association or the
Master Declarant, as the case may be, against the Association and the Owners as provided in the
Master Declaration. The Association shall pay to the Master Association or the Master Declarant,
as the case may be, its share of the Master Declaration assessment as provided in the Master
RALEIGH 345594.1 57
DEED BOOK 3507 PAGE 227
discretion, may determine. Activity Cards provided to Declarant shall entitle the bearer to use all
Common Area and recreational facilities (subject to the availability, payment of admission fees or
other use fees charged to Qualified Occupants holding Activity Cards).

Common Area and Recreational Facilities on a fee-for-usage basis so long as it does not charge
the operating expenses for such activities for which fee-for-usage charges are recouped in annual
Assessments. Furthermore, the Association shall be entitled to hire a management company to
operate the Recreational Facilities on the Association's behalf, and such management company
shall not be treated as a club hereunder but shall enjoy the rights and privileges granted to the

Declarant shall have the right from time to time to assign its rights contained in this
section to nonprofit entities selected by Declarant, including without limitation, the Association.
Declarant's right to use the Common Area and Recreational Facilities for special events shall be

benefited Owner shall contribute a pro-rata share for the cost of restoration. However, such
contribution will not prejudice the right to call for a larger contribution from the other users under

appurtenant to the land and shall pass to such Owner's successors-in-title.
F. RELATIONSHIPS WITHIN AND OUTSIDE THE COMMUNITY
The growth and success of Summerwind Plantation as a community in which people

Claim arises);
(iii) the Claimant's proposed resolution or remedy; and
(iv) the Claimant's desire to meet with the Respondent to discuss in
good faith ways to resolve the Claim.
(b) Negotiation. The Claimant and Respondent shall make every reasonable effort to
meet in person and confer for the purpose of resolving the Claim by good faith negotiation. If
requested in writing, accompanied by a copy of the Notice, the Board may appoint a
representative to assist the parties in negotiating a resolution of the Claim.
(c) Mediation. If the Bound Parties have not resolved the Claim through negotiation
within thirty (30) days of the date of the Notice (or within such other agreed upon period), the
Claimant shall have thirty (30) additional days to submit the Claim to mediation with an entity
designated by the Association (if the Association is not a party to the Claim) or to an independent
agency providing dispute resolution services in the Raleigh/Clayton/Johnston County
metropolitan area. Each Bound Party shall submit to the mediator a written summary of the
Claim.
If the Claimant does not submit the Claim to mediation within such time, or does not
appear for and participate in good faith in the mediation when scheduled, the Claimant shall be
deemed to have waived the Claim, and the Respondent shall be relieved of any and all liability to
the Claimant (but not third parties) on account of such Claim.
If the Bound Parties do not settle the Claim within thirty (30) days after submitting the
matter to mediation, or within such time as determined reasonable by the mediator, the mediator
shall issue a notice of termination of the mediation proceedings indicating that the parties are at
an impasse and the date that mediation was terminated. The Claimant shall thereafter be entitled
to file suit or to initiate administrative proceedings on the Claim, as appropriate.
Each Bound Party shall bear its own costs of the mediation, including attorneys' fees and
each Party shall share equally all fees charged by the mediator.
(d) Settlement. Any settlement of the Claim through negotiation or mediation shall
be documented in writing and signed by the Bound Parties. If any Bound Party thereafter fails to
abide by the terms of such agreement, then any other Bound Parry may file suit or initiate
administrative proceedings to enforce such agreement without the need to again comply with the
procedures set forth in this section. In such event, the Bound Party taking action to enforce the
agreement shall, upon prevailing, be entitled to recover from the non-complying Bound Party (or
each one in equal proportions) all costs incurred in enforcing such agreement, including, without
limitation, attorneys' fees and court costs.

173 Notice to Association

written response from the Mortgagee within thirty (30) days of the date of the Association's
request provided such request is delivered to the Mortgagee by certified or registered mail, return

21.1 By Declarant.
In addition to specific amendment rights granted elsewhere in this Declaration, until a Lot
is conveyed to a Person other than a Builder, Declarant may unilaterally amend this Declaration
for any purpose. Thereafter, Declarant may unilaterally amend this Declaration if such

governmental lender, purchaser, insurer or guarantor of mortgage loans, including, for example,
the Federal National Mortgage Association or Federal Home Loan Mortgage Corporation, to
make, purchase, insure or guarantee mortgage loans on the Lots; (d) to correct clerical or
technical errors; or (e) to satisfy the requirements of any local, state or federal governmental
agency. However, any such amendment shall not adversely affect the title to any Lot unless the
Owner shall consent in writing.
So long as Declarant owns property described on Exhibit A or Exhibit B for development
as part of Summerwind Plantation, it may unilaterally amend this Declaration for any other
purpose, provided the amendment has no materially adverse effect upon the rights of the
Members. In addition, Declarant shall have the right to amend provisions affecting particular Lots
for any reasons with the prior written consent of the Owners thereof.
21.2 By Members.
Except as otherwise specifically provided above and elsewhere in this Declaration, this

thereof, of Members representing seventy-five percent (75%) of the total votes in the Association,
including seventy-five percent (75%) of the Member votes held by Members other than

Declaration or which may become subject to this Declaration in accordance with the terms
hereof. In addition, the approval requirements set forth in Article XVI hereof shall be met, if
applicable. Any amendments approved as provided herein shall be Recorded in every county in
