Proj ct d scription
The Woods of Weddington is a single family residential neighborhood. It is composed of 124 lots
that are all in excess of 40,000 square feet. It also has a significant area of common open space
primarily located along the streams in the project. The requirements for development in the
community require the use of curb and gutter. In order to best deal with water quality and mitigate
the channelizing that the use of curb and gutter creates, the project has been designed with several
innovative and site specific design features that provide better water quality than a typical low
density neighborhood without curb and gutter.
Sit sp cific d sign f atur s
The design features that are site specific include maintaining the flood plains and Creekside areas in
the existing natural state with as little disturbance as possible. The storm drainage system is
designed to have as many small drainage areas as possible using smaller pipes discharging to
vegetated swales that discharge into natural drainage ways in critically identified areas. In other
areas that are not as critical, an extra measure to diffuse storm water discharge has been provided
that exceeds the standard. The rip rap apron required has been shown to be widened 1.5 times
wider than the minimum design. There are three reasons for not including a vegetated swale. The
first area is where the existing terrain is too steep to allow for a 100 foot vegetated swale (FES 79
and 121). This will allow existing, established vegetation to remain to accept the runoff. The second
area is along the south west overbank of Mundy's Run where a natural shallow swale exists and is
already vegetated (FES 16, 28, and 103). It is the engineer's recommendation that this natural feature
should be utilized as it meets the criteria to dissipate flow energy and has vegetation, rather than to
remove established vegetation in lieu of a manmade structure that needs extra maintenance and is
not actually native to the riverine overbank environment. A flow path has been added to the plans to
show where runoff will travel. Only areas where a minimum of a 150 foot flow path of natural
vegetation, parallel to the stream will not have engineered swales for this condition. The third
situation occurs at FES 93 where a minor amount of curb drainage is contributed from CB's 91 and
92. Additionally, most of the property drains naturally across the ground to natural drainage ways.
Only 35 percent of the neighborhood drains to curb and gutter in streets with the rest draining away
from streets similar to a typical low density development. The drainage areas that go to curb and
gutter are discharged to flood plain and are further filtered by vegetated swales. Much of the non
curb outlet runoff into the flood plain is naturally diffused over 500 feet of flat naturally vegetated
area prior to getting into the creek. To comply with the requirement of the vegetative stream buffer,
The Woods project intends to restrict development activity to areas outside the floodplain along
Mundy's Creek, with the exception of the Castleton culvert crossing. The floodplain line will mostly
serve as the required buffer, however, in areas where it is less than the required 30 feet from the
creek, an additional vegetative stream buffer shall be shown and recorded on the final plat.
Innovativ d sign f atur s
The Woods of Weddington has incorporated numerous unique design features to minimize
environmental impact. Due to the custom design nature of each home site, the developer is able to
require special conditions on the builders in order to enhance both the neighborhood and the
environment. The applicable conditions are listed on the submitted plans. Of special note is the

requirement that all homes meet the proposed disconnected structure requirements. Since the
entire parcel consists of type B soils, the type 3 standard is required for all homes. This gives us
water quality treatment efficiency of 85% TSS, 30%Tn, and 35% Tp.
Additionally, the diffusion of water from impervious surfaces also affects total stormwater runoff
characteristics by creating more sheet flow than the typical low density home site. On most
homesites, roof drainage is discharged from downspouts almost immediately to swales and
concentrated flow. The attached calculations show that this design reduces runoff from the typical
low density development without curb and gutter.
Post D v lop d Runoff Analysis
The Woods project intends to utilize a Best Management Practice (BMP) called Disconnected Impervious
Surfaces. The principle of this BMP is isolating impervious surfaces and surrounding these surfaces with a
dense vegetation that lessens the impact of rainfall runoff. A requirement of this BMP is the project must be
less than 24% built upon area (impervious). The following table demonstrates the Phase 1 of The Woods
development meets this criteria.

Built Upon Ratio:
22.43%
As indicated above the proposed built upon ratio is 22.43%. This is due to large areas of common open space
that is to remain undeveloped. RDDavis Engineers has developed an analysis to compare just the developed

portion of Phase 1, excluding most of the undeveloped common areas. This is to demonstrate the impact of
the development as well as to serve as a base comparison for a hypothetical analysis. As for the roofs figure,
the calculation includes all built upon area that is not a driveway. The roofs area include impervious areas such
as patios, pools, detached garages and any other possible impervious surface. The maximum built upon area
per lot is assumed in this calculation as a worst case scenario. As indicated in the following table, the
developed area of Phase 1 indicates a built upon ratio of 25.86%. The hypothetical scenario reduces the built
upon areas to achieve an aggregate 24% or less in the same analysis area. Also it is assumed the BMP
requirements do not apply, therefore reducing the quality of the vegetated areas surrounding the built upon
areas. Based on this information, a proposed model and a hypothetical model was created. This data was
entered into a hydrology analysis software. The proposed model uses the minimum BMP requirements as
stated in the following section, that the surfaces surrounding built upon areas are to be vegetated. This
vegetation in the analysis software is grass with a coverage area of greater than 75%. That ground cover
generates a runoff curve number of 61. In the hypothetical model this ground cover is assumed to be grass at
a coverage rate of 50 to 75% due to the lack of BMP requirements. The method used to estimate runoff
incorporates a sheet flow path used for calculating time of concentration. The method recommends a length
of sheet flow from 100 to 300 feet. It has been widely accepted that 300 feet is too long of a flow length and
that the conditions in this area warrant the "normal" length of 100 feet. In three locations, it is estimated that
the sheet flow length can reasonably be extended to 200 feet due to the runoff characteristic of dense grass. It
is of note that the other individual lot treatment options are not considered in these models. It is assumed
that the other options will further increase the treatment of initial runoff and reduce the peak runoff in 2 year
rainfalls and more frequent rainfall events.
Incorporated by reference are Drainage Area Maps, sheets 1 and 2 to indicate areas for analysis as well as
supporting calculations.

As presented above, the proposed condition creates lower rainfall runoff due to all of the conditions detailed
above as compared to a development that would be below 24% built upon area with no BMP controls.

Post D v lop d Runoff Tr atm nt Plan
This next section is how The Woods development intends to meet the Phase II requirements to reduce TSS
pollution. This plan will be recorded with the covenants and restrictions in the Union County Register of
Deeds.
Potential MDC for Disconnected Impervious Surfaces
1. For disconnected roofs, a maximum of 300 square feet of roof shall drain to each
disconnected downspout unless a device (like a level spreader) is provided to spread the flow
evenly across the entire width of the vegetated receiving area. If there is a spreading device,
then the drainage area may be increased to 500 square feet. The receiving vegetated area
shall be a rectangle of either 6 by 12 feet or 12 by 24 feet (width of vegetated area by length
of run in direction of flow). The entire rectangle shall not include any impervious surface to
ensure that water released from the roof does not run onto another impervious surface.
2. For disconnected pavement, the receiving vegetated area shall be either 10 or 15 feet long.
The maximum width of pavement run that may discharge to the vegetated area is 100 feet
and the maximum slope of the pavement shall be 7 percent.
3. The vegetated area shall have a maximum slope of 7 percent with land graded to promote
sheet flow, except in A soils where the maximum slope is 15 percent.
4. If the vegetated area is established on fill soils that are less permeable than the in situ soils,
then the soil type for crediting purposes shall be based on the fill soils. However, if the fill
soils are more permeable than the in situ soils, then the soil type for crediting shall reflect the
in situ soil type.
5. The vegetated receiving area shall not contain any impervious surface.
6. The vegetated cover shall be a non clumping, deep rooted grass species. For disconnected
downspouts, the vegetated area shall be kept off line until vegetation has been established.
For disconnected pavement, soils shall be stabilized with temporary means such as straw or
matting until the permanent vegetative cover has taken root.
7. The vegetated area shall be uniformly graded with no gullies, low spots or lateral slopes.
8. All sites built within the past fifty years shall be tilled to eight inches prior to vegetation
establishment.
9. Recommended: A minimum separation of five feet should be provided between the
disconnected downspout and the foundation.
10. Recommended: Do not use wooded areas as vegetated receiving areas because uneven
micro topography often causes channelization, which reduces surface area exposed to
stormwater.

1.0 The Woods of Weddington Master Plan
The Woods of Weddington, ("The Woods") is a master planned community designed for an exceptional living environment with large
custom home sites for enduring property and building value. The following are project guidelines and standards to assure that every
property Lot Owner adheres to approved standards. The intent is for each home site improvement to be complimentary to the architecture
and environment within the subdivision. The Woods is comprised of exceptional acre lots mixed with open fields, hardwoods, hillsides and
creeks in an area that consists of natural hillside lots and gradable lots that are left in their natural state. The natural beauty of The Woods
landscape is meant to be preserved and enhanced as the development grows to conserve the natural eco -systems, wildlife, indigenous
plants and streams. It is the further intent and purpose of these restrictions and covenants to protect, to maintain and enhance the
conservation of natural and scenic resources, to promote the conservation of soils, wet lands, wildlife, game and migratory birds, enhance
the value of abutting and neighboring properties adjacent to such forests, wildlife preserves, natural reservations or sanctuaries or other
open areas and open spaces, and to afford and enhance recreation opportunities, preserve historical sites and implement generally The
Woods Master Plan.
Pursuant to its overall goal of wildlife conservation and nature study, the right is expressly reserved to The Woods to erect wildlife feeding
stations, to plant small patches of cover and food crops for quail, turkey and other wildlife, to make access trails or paths or boardwalks
through said Open Space Areas and Private Open Space Areas for the purpose of permitting observation and study of wildlife, hiking, the
nature trails, to erect small signs throughout the Open Space Areas and Private Open Space Areas designating points of particular interest
and attraction, and to take such other steps as are reasonable, necessary and proper to further the aims and purposes of the open space
community use and enjoyment thereof.
1.1 The Woods of Weddington Image
To promote a classic Piedmont Carolina image, the land plan includes distinctive entrances, rustic street signs and lighting, and nature trails
along historical Mundys Run Creek that meanders through the property. The footprint of each home and the building envelope shall blend
into the natural environment of each lot and its unique characteristics.The sizable nature of these lots was a prerequisite to establish a
custom home community with long meandering drives, estate style custom homes set back in what nature already has in place.
Guidelines and controls for complementary architectural and landscape design are necessary to accomplish the intent of the land plan,
preserve and enhance the natural endowments of the property, and ensure the integrity of the subdivision.
Complete site and landscaping plans for each private residence will be required to uphold this pledge to enhance the native habitat by using
mature indigenous vegetation. Wherever possible, trees should be preserved and protected to enhance the beauty and value of properties
within the Estate. Mature trees should be especially guarded and utilized to give shade and shelter to homes.
Functional site and home design strategies are greatly encouraged for greater efficiency, reflective of our need for energy conservation and
reduced carbon footprint. Technologies and systems shall be incorporated within each home constructed. Architectural elevations however
must reflect the charm of our Carolina Piedmont region, complimentary timeless designs that will be enjoyed for many generations.
These design guidelines and standards along with the Covenants, Conditions, and Restrictions (CCRs) for The Woods work together to
establish minimum practices to be observed by all property Lot Owners and users in the subdivision.
1.2 Site Layout
Preservation of the natural setting is one of the central goals along with the promotion of aesthetically attractive custom structures and the
protection of property values in The Woods. All of these goals are attained by adherence to the CCR's and these Guidelines.
Emphasis at The Woods shall be towards the preservation of the natural beauty of the native landscape. Preserving the native flora of the
region while, at the same time, providing reasonable flexibility to the property Lot Owner to make the desired and necessary improvements
to their property, is essential in the development of an estate lot community.
Care has been taken in the placement of the numerous natural open areas as well as the roads and the layout of each lot in order to
preserve the natural features of the Site. The design of each residence will require its own site specific sensitive approach to take advantage
of the special opportunities unique to each lot. The location of any structure into the natural environment must be accomplished with
minimal disturbance to the land. The goal of these Design Guidelines and Standards are to:
• Preserve the character of each lot by way of development that is appropriate to its setting.
• Achieve harmony with the natural environment by striving for minimal visual impact of the buildings on the landscape.

• Achieve harmony in the building environment by stimulating a natural and agreeable diversity.
These Guidelines serve as a supplement to the Covenants Codes and Restrictions (CCR's). They illustrate and define design objectives for a
unified and harmonious style for The Woods.
The information in these guidelines is presented as a convenient reference to assist property Lot Owners, their Architects, Engineers,
Designers and Custom Home Builders in the most advantageous adaptation of The Woods for development and construction.
Location, size, style, color, and types of signs, buildings, walls, vegetation, ornaments, drainage, building materials and other design
elements are described in the following pages.
Illustrative examples and descriptions are meant to ensure an orderly and a well-maintained sense of community and spaciousness.
These guidelines are based on two fundamental concepts. The first is the Building Envelope concept.
Minimize intrusion into, or disturbance of the natural areas, and;
Assure reliable open spaces between buildings that will remain undisturbed as permanent view corridors.
The second is the S ite-Specific concept.
This concept requires that each custom home and yard be specifically designed, site plan reviewed on site and approved to fit the site
rather than reconfiguring the site to accommodate a preconceived design.
This approach will assure a natural and appropriate diversity and result in improvements that are compatible with their sites and over all
environments of The Woods.
2.0 Architectural Review Committee (ARC)
The Architectural Review Committee (ARC) is an entity established to review and evaluate all plans and specifications for any and all
proposed improvements and alterations in the subdivision. All aspects of architecture and landscaping are subject to review and approval
by the ARC. The authority for the establishment of the ARC is provided by the Master Declaration of Covenants, Conditions and Restrictions
for The Woods of Weddington (the " Declaration ").The ARC has adopted these Design Guidelines and Procedures ("Guidelines") to serve as
a guide for the review and control process.
The Guidelines, procedures and their associated fees may be amended at any time by the ARC. No prior notices or announcements will be
required to amend the Guidelines and the ARC has no obligation to circulate such revisions. However, no changes shall be made that are
not allowed by the approved 401 water quality plan without an approved revision by the appropriate department of the North Carolina
Department of Natural Resources.
The ARC will also set guidelines for proper lot preparation and conditions throughout the term of construction and make sure final steps
have been taken prior to any occupancy or project closeout.
3.0 The Building Envelope
As a part of the original planning process for The Woods, special areas of each lot are designated by each lot drawing as the Building
Envelope within which all improvements must occur. The design of each Building Envelope was based upon the unique features of each Lot,
views, and relationship to other Building Envelopes and topography.
Alteration of the Lot is permitted only within the Building Envelope. Modification of the Building Envelope is discouraged, and may be made
only with the prior written Approval of the ARC, following procedures outlined in these Guidelines.
These building envelopes shall meet with the Building setbacks and promote harmonious and consistent appearance throughout the
development as well as ensure there are no encroachments onto established utility easements, drainage easements, subdivision amenities
or neighboring properties.
3.1 Definition
No building on any Lot (including any stoops or porches, patios, terraces, etc.) shall be erected or permitted to remain outside of the
"Building Envelope" for that particular Lot as established by the ARC (as on each Lot ,the "Building Envelope"). The Building Envelope
approved for any Lot will be available from the ARC on an unrecorded map. This map will be provided to the builder/owner in an electronic
format that will allow the precise staking of the limits of the building envelope on the ground.
The ARC shall have the right in its sole discretion to make exceptions to any Building Envelope to recognize any special topography,
vegetation, Lot shape or dimension, or other site -related conditions. In the event of any zoning or subdivision ordinance, floodway
regulation or other ordinance, law or regulation applicable to a Lot shall prescribe greater setbacks, which all buildings erected during the
pendency of such requirements shall conform hereto.
The Building Envelope represents the area in which all residential improvements must be built including adequate construction access
around the perimeter.
The size of the Building Envelope will be determined by the Developer, and may be modified by the ARC.
1. The Building Envelope will consist of the area as defined on the lot envelope plat for the lot.
2. All building and construction disturbance must remain in this area for the residence.

3. Each Lot Owner in this section will be allowed to grade the lot within the Building Envelope, as established by theARC.
4. Each lot will require building permit approvals with copy to the ARC from Union County and architectural, engineering,
landscaping, grading, erosion control and drainage plans submitted to the Architectural Control Review Committee for
review, and final recommendations on an individual basis, prior to any site construction.
5. Each lot will require an inspection and review meeting with the Lot Owner and/or its Custom Home Builder by the ARC
prior to any excavation or grading.
This ARC may require and/or permit slight adjustments to the Building Envelope. Consideration will be given to adjustments that pose no
injury or detriment to the overall site and no negative impact to any other homeowner or the Natural Area. If, in the opinion of the ARC,
the relaxation of these standards can protect and enhance an existing natural feature such as a tree, consideration will be given for a
variance on a case-by-case basis. To secure such variance, the Lot Owner/Custom Home Builder is required to provide evidence in the form
of a tree survey or provide photographs that verify the existence and character of the site feature causing the variance request. In no case
shall the building envelope become larger or closer than 25 feet from any environmentally sensitive area or feature.
Prior to the placement of any forms, Lot Owner/Custom Home Builder should review the recorded final plat and these Guidelines for the
specific lot to verify all setback and Building Envelope requirements. Property Lot Owners are encouraged to obtain written confirmation
from their Custom Home Builder that all setback requirements have been met prior to the start of any construction of the residence.
All such setback and easement provisions will be reviewed at the jobsite preconstruction meeting.
3.2 Natural Areas
The Natural Area is that portion of the lot outside the Building Envelope that has been or is designated as a Natural Area by the
Architectural Committee. This area is to be left in its natural condition. Where scarred areas exist outside the Building Envelope, re -
vegetation is required to restore it to its natural state.
The extent of the re -vegetation and supplemental planting will be determined at the Pre -Design Meeting. All re -vegetation plant materials
must be consistent in species and density with what generally exist in the area.
3.3 Transitional Areas
The Transitional Area is that portion of the lot that is outside the Building Envelope, and not in a Natural Area. The purpose of the
Transitional Area is to provide a gradual transition between the Building Envelope and the neighboring Lot Owners, the Natural Areas and
the site improvements without establishing a strong contrast in appearance.
The idea of the Transitional Area is to make certain that the Building Envelope line is not in any way evident in the landscape. Any change
from the Natural Area to landscaping around the residence is to be gradual. The Transitional Area is vital to the relationship to the Natural
Area to theLots.
The landscaping requirements of the ARC shall review the Natural Area to Lot relationship with consideration to the Lots and the views and
the views from the Natural Areas.
3.4 Private Area
The Private Area is that portion of the Building Envelope that is not visible from adjacent properties, streets or public spaces because it is
screened behind walls or structures. The Private Area is the least restrictive in terms of plant materials.
The Lot Owner may install any plant material in the Private Area, except the prohibited plants listed in these guidelines. Any plants that will
grow above the wall heights will need to be approved by the ARC.
3.5 Front Yard area
The front yard area is the portion of the site that extends from the front of the building envelope to the street zone. This area will include
the walkway to the front door and the driveway that is designed to be curvilinear and drain water into yard and natural area as much as is
possible given the terrain. The ARC shall be the sole arbiter of whether or not the intent of this requirement is met. The front yard area
nearest the home shall be treated largely like the transitional area. All trees over 4 inches DBH in this zone shall be located on the
proposed site plan and all such trees to be removed must be approved by the ARC. Wherever possible, a minimum of 50% natural area of
trees shall be left in the front yard area. Where insufficient existing tree areas exist, supplemental plantings shall be installed.
3.5 Street Zone
The Street Zone is that portion of the site that occurs between the front yard and the street edge. Supplemental planting may be required
to augment the existing vegetation and to create an attractive streetscape.
3.6 Conservation Easement, Open Space Areas and Other Easements
Areas are designated on the plat as permanent exclusive easements for the construction, operation and maintenance operations for the
nature trails at The Woods. No Lot Owner or Custom Home Builder shall be permitted to disturb any of nature trail areas, landscaping, or
structures.
The ARC shall have no authority to approve any modifications of the Conservation Easement.

The Woods reserves unto itself, its successors and assigns a perpetual, alienable and releasable easement of right to go on, over and under
the ground to erect, maintain and use electric, telephone, wires, cables, conduits, drainage ways, sewers, water mains, and other suitable
equipment for the conveyance and use of electricity, telephone equipment, gas, sewer, water drainage or other public conveniences or
utilities in said Open Space Areas. These reservations and rights expressly include the right to cut trees, bushes, or shrubbery, rights to
make any grading of the soil, or take any other similar action reasonably necessary to provide economical and safe utility installation and to
maintain reasonable standards of health, safety and appearance. The Woods further reserves the right to locate wells, pumping stations
and tanks within such Open Space Areas and Private Open Space Areas. Such rights may be exercised by any licensee or assignee of The
Woods, but this reservation shall not be considered an obligation of The Woods to provide or maintain any such utility or service.
4.0 SITE DEVELOPMENT
4.1 Grading, Drainage and Utilities
The following general limitations will apply to all site development:
1. The topography of The Woods varies considerably, and all lots that have not been graded by the Developer and are in their
natural state have natural slope within their Building Envelopes. All improvements, therefore, should attempt to balance the cut
and fill requirements and nestle the building and its site work into the Lot. Every opportunity should be explored to integrate the
drives, pool decks, patios and areas within the residence with the natural topography and vegetation of the lot.
2. Within each building envelope, the maximum amount of impervious area shall be limited to 8,000 square feet or the area of the
building envelope, whichever is smaller. Decks that cover exposed un -compacted earth shall not be considered impervious.
Permeable pavers shall only be considered impervious if they are designed as infiltration devices. Permeable pavers as an
infiltration device will typically have a minimum of 1 foot of washed stone to hold the first inch of runoff to infiltrate into the soil
substrate.
3. While visually integrated retaining walls are preferred and may be required, a building pad may be constructed using the cut and
fill slopes as approved by the ARC. Cut or fill slopes may not extend outside of the Building Envelope. Landscape re -vegetation of
cut and fill areas will be required to;
4. Repair the slopes into the natural environment. In the case of exposed rock cuts, staining to match the adjacent rock surface will
be required. The required building elevations and sections must show the full extent of any intended cut and fill conditions. The
goals are to minimize exposed cut and fill material and to balance cut and fill within the Building Envelope. Natural and finished
contours shall be shown on all grading plans and building elevations.
5. Surface water may drain into adjoining lots or open spaces only as established by natural patterns and shall not be altered to
create a condition which could lead to erosion. Individual grading and drainage approvals from the ARC will be required for all
lots. Drainage from roofs and hard surfaces shall be treated to improve water quality. Methods to accomplish this will be
reviewed and approved by the ARC and shall consist of one of the following options or combination thereof:
A. The roof and impervious area drainage shall be meet the type 3 DIS standard as shown in the details on plans.
B. The impervious area drainage shall be routed to a cistern sized to accept 1 inch of runoff without overflowing. The
cistern shall be equipped with an automatically actuated pump/irrigation system that will delay the start of irrigation
for 48 hours after the rainfall event. A spray irrigation or other system shall apply the stored water to areas within
the yard in such a manner as to not create significant runoff leaving the property.
C. The impervious area drainage shall drain into an appropriately sized sand filter, wet pond, or other treatment option
per the North Carolina Department of Environmental Quality Stormwater BMP manual. A wet pond for example
could be a decorative landscape pond that has vegetation that is periodically covered by stored water retained from
the first 1 inch of runoff and is gradually released over the next 2 to 5 days.
Grading or construction access will not be permitted outside the Building Envelope and driveway unless approved by the ARC.
Trees identified within the Building Envelope that do not conflict with the proposed structure, shall remain if in the opinion of
the ARC the tree will be able to thrive. All trees with a trunk caliper over 4", 24" from the existing ground level, within the areas
to be disturbed during construction shall be flagged and shown on all submittals to the ARC. All trees that shall be saved must be
protected with tree protection fencing prior to the commencement of construction. Tree protection fencing must be placed five
(5) feet beyond the dripline of the trees to be saved, unless otherwise approved by the ARC.
4.2 Transitional Area
The Transitional Area is that part of the Lot that lies between the Natural Areas and the wall of Residence or Improvement, and is visible
from Neighboring Lots. As a final stage if completing construction, any disturbed part of the Transition Area must be planted or replanted
to match and blend in with the adjacent Natural Area.
For any planting, except in the Private Area, must be specifically identified on the Landscaping Plan, and specifically approved by the ARC
before planting.
An irrigation system, carefully designed and installed to preclude overspray or runoff onto the Natural Area, must be installed to support
and sustain the all the landscaped and disturbed areas of the Lot, except Natural Areas. Wells are allowed only for irrigation cannot be
viewable from the street side of the lot. No streams or existing ponds can be used for irrigation.

4.3 Natural Areas Impact
In any community with a Natural Area that may include Nature Trails, foot bridges, etc., there are inherent risks that Natural Areas may
impact nearby Lots, and the Residences thereon. Therefore, the ARC strongly recommends that from the beginning of the development
planning for a Lot, thorough consideration is given to the possibility of use of the Nature trails. This is especially important in the location
of patios, pools and other outdoor living areas, as well as the orientation of windows and other breakable surfaces of a Residence. Screens,
excessively dense landscaping, fences or large blank walls are not allowed.
Careful and thorough evaluation and planning of the areas where people are likely to be present, integrated into the Structure siting,
orientation, massing and setbacks should minimize the impact of, and potential conflict with the Nature trail activity. That planning should
also include consideration of the sound and noise generated by walkers and maintenance equipment.
The ARC and the Association are not responsible for any damage or injuries attributable to the location of a Lot near the Nature trails.
4.4 Setbacks
Setbacks allowed by the Town of Weddington zoning ordinance could b less restrictive than those approved by the ARC. In such a case the
ARC will govern.
4.5 Entrance Driveways Topography or other considerations will suggest the location of driveways within the Building Envelope and
the front yard area. Driveways shall be carefully designed using materials, textures, patterns and colors that minimize reflectivity. The
use of interlocking pavers, brick pavers stamped and colored concrete and brick borders is permitted. The use of permeable interlocking
pavers and pavements is encouraged. Color, pattern, and design will require ARC approval prior to installation and construction.
1. All driveways must be constructed with a minimum width of ten feet (10') from the garage to the abutting street. The
portion of the driveway from the maneuvering area at the garage to the street shall not be more than 12 feet (12) wide.
2. ALL driveways must be a minimum distance of five feet (5') from the side property line, unless otherwise approved by the
ARC.
3. To the extent possible, meandering driveways that make a curvilinear path are to be constructed.
4. Driveways shall be constructed such that they direct water to the lawn and natural areas and minimize runoff into the
street.
5. Whenever possible, driveways are to be de-emphasized, highlighting instead the building and landscape environment.
6. Turnaround or circular drives maybe allowed.
7. Under no circumstances may an entire front yard be paved as a driveway.
8. If the driveway cannot be constructed such that less than 240 square feet of impervious area is discharged directly to the
street, permeable pavers or other measures must be employed to allow infiltration into the subgrade prior to reaching the
street.
The driveway approach, any concrete culvert and temporary construction roadway material must be installed prior to any other
construction activities on the lot and shall be used as the entrance to the property for construction of residence.
Either the permanent or a temporary installation of crushed concrete or other hard surface drive shall be constructed to prevent the tracking
of mud and construction debris into the streets. No vehicles shall drive through the streetscape zone at any location except for the driveway.
4.6 Restricted Activities Regarding Streams
The Property contains one or more streams that mayor may not be Common Area or in the Conservation Easement. With respect to
construction of any Improvements on any Lot that abuts a stream, a silt fence or barrier shall be placed on each such Lot during the
construction of any Improvements thereon in such manner as to protect the stream from soil erosion and silt.
Such fence or barrier shall be constructed prior to the commencement of any construction of Improvements, including clearing or grading,
and shall remain in place and maintained until such time as the said Lot has been landscaped or stabilized in a manner that will protect
the stream from soil erosion and silt.
No pesticides, fertilizers, or other toxic, hazardous or harmful chemicals shall be used for any purposes whatsoever within thirty (30) feet
of any stream.
Any such chemicals used or applied more than thirty (30) feet from any lake or pond shall be used or applied so as to prevent the spread
or dissemination of such chemicals into the stream or downstream lake or pond.
No bridges, storage facilities or other similar structures shall be constructed or located on or in any portion of the streams. No man made
or earth made item shall be permitted in or on any portion of the stream. No Person shall be allowed to swim fish or engage in any other
recreational activities within the streams.
The ARC will review the drainage patterns of surface water that drains into a stream for compliance with the Declarations and for
environmental sensitivity.

5.0 Landscape Reauirements
Because of the nature oft these lots, set specifically for custom homes, special landscape requirements are required of each home Lot
Owner. These requirements are intended to bring about a unified, lush, theme streetscape that is different, yet complements the native
landscape.
The following descriptive plan is meant to define landscape areas and features:
1. Established drainage patterns and conditions must be considered and addressed as a part of the approval for the
construction of improvements of the Lot.
2. Existing contours shall be preserved whenever possible. Gentle mounding, terraced elevation changes and contouring
must coordinate with drainage patterns, and should be designed to enhance the residence's setting and landscaping.
Slope banks shall not exceed 3 'in height with a maximum 4:1 slope ratio. There shall be smooth transitions to adjacent
grading
3. The street zone landscape is a critical element in the overall aesthetic of the neighborhood. The ARC will require
sensitive, coordinated, and functional street zone landscapes. The street zone landscape area shall be determined by
multiplying the lot width by the distances from curb to the building face and side yard walls. This area shall include
driveways, walks, and courtyards.
4. Trees shall be selected from the Approved Plant List and planted at the rate of one tree per 600 square feet of street
zone landscape area. At a minimum, each front yard shall have four (4) 6"caliper trees. Trees should be planted to
provide shade, screen and soften wall surfaces, and accent the architecture of the residence.
5. Shrubs and round covers shall be planted in adequate quantities to soften the transition from building to ground, accent
courtyard walls, provide accent and color at entry paths, and soften walls or large areas of paving. Shrubs and ground
covers should be planted in pleasing groupings that are in harmony with the irrespective growth characteristics.
6. Shrubs shall be selected from Approved Plant List and planted at a rate of one (1) five -gallon shrub per 100 Square feet of
street zone landscape area gallon shrub per 100 square feet of street zone landscape area, and one (1) one -gallon shrub
per.75 square feet of street zone landscape area. As a minimum, there shall be thirty (30) five -gallon shrubs and forty
(40) one gallon shrubs.
7. Approved concealed edging materials should separate and define planting areas; of contrasting elements, i.e.; turf from
paving, shrub beds from turf. When turf is utilized, it shall be maintained year round.
8. Native specimen plants are encouraged to be planted in the Transition Areas or the Street zone. A mature oak (24" in
diameter) can be substituted for three 6" caliper trees in the front yard requirements. Other mature tree specimens can
be substituted or added to reduce the shrub planting requirements.
9. Landscape beds shall be kept mulched and in a neat and weed free manner. Accent areas of boulders and mounding are
encouraged. Specifically prohibited are colored stone, cinders, formal geometric patterning, and common gravel. Design
coordination between neighbors is encouraged. Similar grading, granite and plant materials can be utilized so one
landscape flows to another. If a physical separation is required, edging materials, garden walls, etc. shall blend with the
landscape and home architecture. Specifically prohibited are wood edgings, above grade railroad ties, timber retaining
walls, vertical wood poles, scalloped shape pre -cast concrete elements, or similar elements.
10. Driveways, walks and courts shall be of a rough finish colored concrete that blends with the selected home, Pre -cast
pavers, exposed aggregate concrete, "patterned" concrete, macadam, brick and stone are encouraged as drive and
walkway materials. Specifically prohibited is asphalt, smooth finishes, and painted concrete, and gravel, provided
however, such prohibition shall not apply to areas located within designated Common Areas or The Natural Area.
11. Landscape lighting must conform to the zoning stipulations of The Woods. See lighting for requirements and
prohibitions.
12. Rear yard landscape shall utilize plants from the Approved Plant List and must be installed prior to receipt of Certificate
of Occupancy.
5.1 Landscape Requirements for the Natural Area
Because of the Lots' unique land form and native vegetation, Building Envelopes have been established to preserve the majority of the site
in its present undisturbed state. The following requirements are intended to establish landscape re -vegetation criteria for blending new
residences into the fabric of the existing landscape and establish landscape criteria for the Natural Areas and use are as of the residence. No
physical construction or grading is permitted outside of the Building Envelope except for driveway access to the street.
The following descriptive plan is meant to define landscape areas and features:
The area inside the Natural Areas shall remain in it natural state. Grading, construction vehicles, storage of building
supplies, etc. are expressly prohibited inside the Natural Areas. If any damage occurs, the homeowner will be required to
return the disturbed area to its original condition. Any areas of undisturbed or previously scarred Natural Area that the
homeowner wishes or is required to enhance shall be done with the use of native plants. See Native Plant List, for

approved trees, shrubs, and ground covers. Plantings will be limited to the addition of trees, or shrubbery to screen or
accent site and/or offsite features or to cover bare or previously scarred areas.
2. Limited permanent irrigation will be permitted inside the Natural Areas. Watering of enhancement plants will be by hose
or other approved temporary, above ground methods. No trenching will only be permitted on a case by case limited
basis. Hoses, if utilized, shall be stored out of view. Temporary irrigation must be removed after establishment period.
3. The Transition Area is defined as the area of the Building Envelope that is between the Property Line and/or Natural Area
easement and the Building Envelope and is not permitted to be disturbed by the ARC or impacted by construction. The
Transition Area will require careful planning and execution of landscape design. A portion of this area if disturbed may
require revegetation with natural materials approved by the ARC.
4. The general concept of re -vegetation is to blend the residence into the native landscape by utilizing the same varieties
and densities of plant materials adjacent to the Building Envelope.
5. Trees shall be selected from the native plant list and planted at the rate of one (1) 6" caliper tree per 600 square feet of
Transition Area. Transition Area shall be as shown on the lot envelope plat. Credit will be given for existing plant material
in good condition.
6. Shrubs and ground covers shall be selected from the native plant list shall be planted to adequately blend disturbed areas
into undisturbed areas and soften walls, graded areas, etc. Planting shall reflect the size, type, and density of the
undisturbed areas of the site. As a minimum, there shall be thirty (30) five gallon shrubs and forty (40) one gallon shrubs
shall be planted in the Transition Area. Shrubs shall be selected from the Approved Plant List and planted at a rate of one
(1) five gallon shrub per 100 square feet of Transition Area, and one (1) one gallon shrub per 75 square feet of Transition
Area. Approved concealed edging materials should separate and define planting areas of contrasting elements, i.e.; turf
from paving; shrub beds from turf.
7. Native soil shall be fine graded and contoured to blend with the envelope boundary. Native rock can be utilized to create
or continue drainage ways. The use of native boulders is encouraged as accents and for grade changes in place of
retaining walls. Native wash or creek areas should remain in their natural state. Additional accent elements of gentle
contouring and native landscape materials are encouraged.
8. Construction scarring of areas adjacent to the drive shall be re -vegetated with the same plant varieties and densities that
exist in the adjacent natural areas.
9. Within the Transition Area, the development of enclosed courtyards is encouraged. These courtyards provide privacy
from the street, additional architectural expression, and create a transition from the beauty of the outdoors to the homes
interior. Courtyards can be landscaped as an oasis by utilizing elements such as water, turf, and lush planting. Non-native
plant varieties can be utilized if their mature height is less than the adjacent courtyard wall.
10. Rear yard landscape within the Building Envelope is encouraged to provide both lush private areas and beautiful vistas
from the Natural Area. Private areas may include turf, pool areas, paved terraces, and lush plantings. Private areas, pools,
decks, walls, fences, and patios are to be in harmony with the site's natural terrain.
11. Fencing of pools and private areas must be carefully designed to provide smooth and harmonious transitions from natural
to developed areas.
12. Side yards within the Building Envelope are usually un fenced and re -vegetated to match the adjacent natural area. If side
yards are fenced to create private areas, the same landscape criteria applies as stated I prior sections. Outside the wall,
the area shall be re -vegetated to the same varieties and densities as the adjacent undisturbed area.
5.2 Tree Protection
The following procedures are recommended to ensure the survival and good health of trees existing within The Woods. The Lot
Owner/Custom Home Builder should use the following guidelines to preserve and protect trees on the construction site.
1. Except as maybe necessary to provide room for construction of improvements in accordance with approved plans
or to remove dead trees, no trees with a caliper of twelve inches (12") or more at a point one foot (1') from the
base of the tree may be removed from a lot unless specifically approved by the ARC. Fines will be levied for
unauthorized removal and failure to protect trees.
2. Tree protection fencing should be placed around drip line of trees to prevent storing of machinery or equipment
which can cause soil compaction and mechanical damage.
3. Excessive pedestrian traffic should not occur within dripline of trees.
4. Soil should not be excavated, spread, spoiled, or otherwise disposed of within dripline of trees. Trash fires or
burning of brush shall not be permitted on any lot.

5. In close areas where fencing to dripline is not possible, protect trunk by strapping (not nailing) a continuous shield
of wood (2"xVW) around the trunk and lay plywood on ground in dripline of tree to prevent compaction of soil by
trucks or machinery.
5.3 Tree Preservation
Where tree clusters are preserved, Lot Owner/Custom Home Builder is encouraged to also preserve understory if possible. This helps
maintain conditions around existing root systems.
Placement of utilities within the dripline is detrimental to chances of survival of trees. If routing utilities outside the dripline is not
possible, keep trench area to a minimum and adhere to tree protection methods described in previous section.
In case of specimen trees, consider boring under the tree root system. Prune trees using horticultural accepted methods to compensate for
any loss of root system.
6.0 Drainage
In contrast to traditional higher density suburban developments where it is necessary to speed up and direct runoff with lot grading and
drainage manipulation, to the greatest extent possible, acreage lot developments utilize existing natural drainage features while keeping
the manipulation of natural drainage features to a minimum. The drainage of roadways and private improvements are important but care
should be taken to not unnecessarily alter or accelerate the surface runoff of the natural drainage ways. All home site lots shall be
constructed to insure that the structure impervious area is disconnected from the subdivision stormwater systems. This is accomplished
by directing rainfall runoff from impervious areas to vegetated areas of broad shallow flow prior to the water concentrating in swales and
ditches.
Swales (small ditches) are to be graded shallow but wide enough to slow runoff. Avoid steep cuts for a natural look. Steep slopes of 3:1 or
more should be broken with retaining walls or steps. Terracing of lawns is encouraged only when the grades are too steep.
Downspout water must be released to a vegetated strip to diffuse water flow. Roof drainage shall be split up to as many discharge
locations as practical. All roof drain outlets shall be directed to the greatest extent possible such that flow is diffused into the landscape
for a distance of at least 20 feet prior to reaching a concentrated flow of water such as a swale, ditch or stream.All roof drainage shall be
directed at least 10 feet away from foundation walls.
It will be the responsibility of each Lot Owner/Custom Home Builder to provide adequate surface, subsurface, slope, and downspout and
gutter drainage solutions for each home. Caution should be used in establishing the foundation elevation so that adequate drainage from
the backyard around to the front and the reverse is not impaired by driveways or slabs.
6.1 Sediment Control
In order to maintain clean streets and prevent siltation into drainage channels, all projects in The Woods are required to practice
sediment control during construction. As soon as earthwork commences, sediment control methods shall be installed in such a way as to
filter all stormwater runoff from the tract into the street.
The sediment control system shall remain in place and in good repair until construction is complete, landscaping is installed, and lawns are
established.
Custom Home Builders shall conform to all regulatory agencies' rules, regulating standards, and criteria governing sediment control to
include, but not limited to, the EPA-NPDES and NCDENR. Custom Home Builders shall be responsible for filing and securing all necessary
permits associated with the particular lot to be built upon.

Table 4-1. Sizing and Credit for DIS
1. All roof shall be constructed as disconnected roofs. For disconnected roofs, a maximum of 300 square feet of
roof shall drain to each disconnected downspout unless a device (like a level spreader) is provided to spread
the flow evenly across the entire width of the vegetated receiving area. If there is a spreading device, then
the drainage area may be increased to 500 square feet. The receiving vegetated area shall be a rectangle of
either 6 by 12 feet or 12 by 24 feet (width of vegetated area by length of run in direction of flow). The entire
rectangle shall not include any impervious surface to ensure that water released from the roof does not run
onto another impervious surface. All homes shall meet the Type 3 DIS standard.
2. For disconnected pavement, the receiving vegetated area shall be either 10 or 15 feet long. The maximum
width of pavement run that may discharge to the vegetated area is 100 feet and the maximum slope of the
pavement shall be 7 percent.
3. The vegetated area shall have a maximum slope of 7 percent with land graded to promote sheet flow, except
in A soils where the maximum slope is 15 percent.
4. If the vegetated area is established on fill soils that are less permeable than the in-situ soils, then the soil type
for crediting purposes shall be based on the fill soils. However, if the fill soils are more permeable than the in-
situ soils, then the soil type for crediting shall reflect the in-situ soil type.
5. The vegetated receiving area shall not contain any impervious surface.
6. The vegetated cover shall be a non -clumping, deep-rooted grass species. For disconnected downspouts, the
vegetated area shall be kept off-line until vegetation has been established. For disconnected pavement, soils
shall be stabilized with temporary means such as straw or matting until the permanent vegetative cover has taken root.
7. The vegetated area shall be uniformly graded with no gullies, low spots or lateral slopes.
8. All sites built within the past fifty years shall be tilled to eight inches prior to vegetation establishment.
9. Recommended: A minimum separation of five feet should be provided between the disconnected downspout
and the foundation.
10. Recommended: Do not use wooded areas as vegetated receiving areas because uneven micro -topography
often causes channelization, which reduces surface area exposed to stormwater.
