Existing Use: Vacant Proposed Use: Single Family Residential Subdivision 5. Utilities provided by Union County Public Works 6. Overall Phase I area = 162.265 ac. Impervious area = 35.59 ac. or 22.439' where: impervious in roads and curb and gutter: 9.41 ac. sidewalks: 0.68 ac. impervious in lots (max): 25.50 ac. I j undisturbed natural area = 68.69 ac. or 42.339' j lawn/other pervious area = 57.99 ac. 7. Area that drains to roods/pipe system: 65.65 ac. total (56.73 ac. I onsite and 8.92 ac. offsite) -----� 8. Area that drains through natural channels (similar to non curb and gutter streets): 105.54 ac. or 651 9. Since 659' drains through natural channel, site is not primarily piped. j 10. Due to the homesites being designed as disconnected, the peak runoff is less than traditional low density subdivisions without curb j and gutter. 11.Typical low density development of 124 lots with ditches and no , disconnection generates a peak flow of = 174.3 cfs for a 2 year design storm event. The proposed design results in a peak flow of the some design storm of 152.6 cfs. 12. By implementing the BMP utilizing disconnected impervious, this design will provide reductions to meet the requirements of 859' TSS, 30% TN and 359' TP. 13. The culvert is designed to work as a bridge and have a restored, naturalized channel through it for normal and low flow periods. No disruption of the travel of aquatic life is anticipated. 14. The culvert will be constructed under a FEMA CLOMR and will be finalized with a FEMA LOMR. The result in the flood study is that the culvert as sized will result in only a 0.6 foot rise for the 100 year storm event and negligible flood rises within 500 feet upstream. Smaller storms result in almost no difference due to the large opening above normal flow levels. `111111111111 ♦♦♦`�� CARo1��'' CARO ..�,,, (/ Z - �- = FIRM -J = v LICENSE = 1005 ; NUMBER �� + P-1445 B G IE.••,, a�- o♦♦ P0 R A� ��rIDi11111♦ 91 6-/ THIS DRAWING IS THE PROPERTY OF ROBERT D.

Swale 6.1 Description Swales are broad, shallow vegetated channels designed to convey and treat runoff and attenuate peak flows from small drainage areas. The purpose of a swale is to decrease the velocity of runoff to promote sedimentation of suspended solids, infiltration and interception of particulates by vegetation. To perform this function, swales typically have denser vegetation and flatter slopes than most drainage channels. When incorporated into roadway or facility design as part of the conveyance system, swales can provide water quality benefits and be aesthetically pleasing. Figure 6-1. Swale with water quality rock check Swales treat runoff through sedimentation, physical filtration, infiltration, and biofiltration. As runoff moves through the vegetated channel, reduction in velocities (and the resultant increase in residence time) allows for greater settling of suspended solids. This process is aided by interception by the vegetation, improving water clarity and removing particulate -bound pollutants such as metals. In sufficiently permeable soils and on shallow slopes without excessive compaction, infiltration plays a significant role in reducing runoff volume. Depending on the residence time and other conditions, removal of metals, nitrogen, and phosphorus may be enhanced through biological uptake. The main component of a swale is the vegetated channel. In some applications, water quality rock checks are incorporated to terrace the swale to maintain a flat effective slope and provide erosion control (Figure 6-1). An example of a swale and its components is shown in Figure 6-2. Figure 6-3 shows a cross section of a swale. LONGITUDINAL SLOPE <4%.

CHANNEL VEGETATION: REFER TO DETAILS ON THIS SHEET FOR PLANT MATERIAL AND INSTALLATION IN THE CHANNEL SECTION. Bank treatments: Live polo cuttings or live stakes Lhro pole cuttings aro dormant stems, branches, or hunks of live, woody plant material inserted into the ground with the purpose of getting them to grow. Live stakes are generally shorter material that are also used as stakes to secure other soil bloengineering treatments such as fascines, brush mathtisaw, erosion control fabric, and coir fascines. However, the terms live stakes and live pole cuttings are often used interchangeably. Both live poles and live cuttings can be used as anchoring stakes. They are live material so they will also root and sprout. Live polo cuttings are 3 to 10 feet long, and 3/4 to 3 inches in diameter. These cuttings typically do not provide immediate reinforcement of soil layers, as they normally do not extend beyond a failure plane. Over time, they provide reinforcement to the soil mantle, as well as surface protection and roughness to the streambank and some control of internal seepage. They assist In quickly reestablishing riparian vegetation and cause sediment deposition in the treated area. Joint plantings Joint plantings or vegetated rfprop aro cuttings of live, woody plant material inserted between the joints or voids of riprap and into the ground below the rock. Joint planting cuttings aro 30 to 48 inches long, and from 3/4 to 2 Inches In diameter. These live cuttings typically do not provide immediate reinforcement of soil layers, as they normally do not extend beyond the failure plane. The live cuttings aro intended to root and develop top growth providing several adjunctive benefits to the riprap. Over time, these installations provide relnforooment to the soil on which the rfprap has been placed, as well as providing roughness (top growth) that typically causes sediment deposition in the treated area. Some control of internal seepage is also provided. These joint planting Installations assist in quickly reestablishing riparian vegetation. Joint plantings aro frequently used on the lower part of the bank. CHANNEL VEGETATION SHALL CONSIST OF A MIXTURE OF FESCUE AND PLANTINGS FROM THE DETAIL ON THIS SHEET.

INSTALL BANK TREATMENTS 2.0' Practice Standards and Specifications Shrub zone—This zone is flooded only when flow exceeds the average high water level. The shrub zone is inhabited by trees and shrubs with high regenera- tive capacity, such as willow, alder, dogwood, and vibumum. Shrub zone vegetation is recommended for the impact bank of a stream meander, where maximum scouring occurs. Infringement of shrub vegetation into the channel reduces channel capacity, however, increasing the frequency of floods. Tree zone—This zone is flooded only during periods of very high water (i.e., the 2 -yr peak flow or greater). Design Criteria Table 6.72a provides general guidelines for maximum allowable velocities in streams to be protected by vegetation. 1. Ensure that channel bottoms are stable before stabilizing channel banks. 2. Keep velocities at bankfull flow nonerosive for the site conditions. 3. Provide mechanical protection such as riprap on the outside of channel bends if bankfull stream velocities approach the maximum allowable for site conditions. Table 6.72a Conditions Where Vegetative Streambank Stabilization is Acceptable Frequency Max. Allowable Velocity Max. Allowable Velocity of Bankfull Flow for Highly Erodible Soil for Erosion Resistant Soil > 4 times/yr 4 ft/sec 5 fVsec 1 to 4 times/yr 5 ft/sec 6 ft/sec < 1 time/yr 6 ft/sec 6 ft/sec Construction Construction guidelines cover only the reed -bank and shrub zones. The aquatic Specifications plant zone is difficult to establish artificially and becomes established natural- ly when reed -bank vegetation is present. The tree zone is seldom flooded and rarely needs stabilization once the reed -bank and shrub zones are stabilized. REED -BANK VEGETATION The following grasses are recommended in North Carolina: Halifax maiden cane (Panicum hemitomon) Common reed (Phragmites communis) Reed canarygrass (Phalaris arundinacea) Common reed is a very robust plant whose stems become woody in autumn, resulting in continued protection during the winter. Because the shoots and rhizomes are deeply and strongly rooted and densely intertwined, they bind soil more firmly than any other reed varieties. However, the common reed grows high and thick, and periodic maintenance may be needed in order to achieve a neat appearance. Dense growth may also increase the frequency of flooding. 0 6.72.3 _7 Rhizomes Clumps Figure 6.72b Methods of establishing reed -bank vegetation (modified from Seibert). 6.72.4 Reed rolls There are various ways of planting reed -bank vegetation (Figure 6.72b). Planting in clumps—The oldest and most common method of planting reeds is planting in clumps. Cut stems of the reed colony to several inches. -Dig clumps out of the ground and place in holes prepared in advance in the area to be sta- bilized. Plant clumps at a depth where they will be normally submerged to a maximum of two-thirds their height. Planting rhizomes and shoots—Less material is needed for planting of rhi- zomes and shoots. Slips of Halifax maiden cane, common reed, and reed canarygrass can be taken from existing beds during the dormant season, after cutting the stems. Carefully remove rhizomes and sprouts from the earth without bruising the buds or the tips of the sprouts. Place in holes or narrow trenches at the average summer water level, so that only sprouts are showing above the soil. Planting stem slips—It is possible to plant stem slips of common reed along slow moving streams. With a dibble bar or some other planting tool, set three slips in holes approximately 12 inches deep and 1 ft apart. Reed rolls—Along flowing streams, reed rolls are the most effective method of establishing reed -bank vegetation. Plants are placed in rolls 1 ft apart. Dig a trench 18 inches wide and 12 inches deep, parallel to the stream. It may be neces- sary to place planks braced with planks along the sides of the trench to keep it open. Place wire netting, such as 1/2 -inch hardware cloth or filter fabric, across the bottom and up both sides of the trench between the upright planks.

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 forgreater 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. 1.1 Site Layout Preservation of the natural settingis one of the central goals along with the promotion ofaesthetically attractive custom structures and the protection of ro erc values in The Woods. All of these goals are attained b adherence to the CCR 'sand these Guidelines. 8 8 p Y p P P Y 8 Y 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 ofan 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 byway of development that is appropriate to its setting. . Achieve harmony with the natural environment bystriving for minima/ visual impact of the buildings on the landscape. • Achieve harmony in the building environment by stimulating a natural and ogreeable 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 ofsigns, 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 Site -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. Z�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. 3.0The Building Envelope _ g P Asa art of the original planning process for The Woods special areas of each lot are designated b 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. P 8 p 8P P 8 Y 8 8 P p 8 8 P p 4 p 8 p 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 ARCshall 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 rade the lot within the Building Envelope, as established b theARC. 8 8 p. Y 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 an 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 P Y / P p Y 8 p q P Y 8 q 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 b 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. P 8 p 8 Y 8 P. 8 q 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 ARCshall 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 and 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 and and natural area as much as is possible given the terrain. The ARC shall be the sole arbiter of whether or not the intent Y p 8 p Y Y 8 Y p 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 an of nature trail areas landscaping, or structures. 8 P P P P P Y P g The ARCshall have no authority approve an to a modifications of the Conservation Easement. Y 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 orshrubbery, rights to make an radio of the soil or take an other similar action reasonably necessary to provide economical and safe utility installation and to maintain reasonable standards of health safety and P P P g P V 8 ry 8 anygrading 8 Y Y Y P tY Y 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 followinggeneral limitations will apply to all site development: 8 PPY P 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 I foot of washed stone to hold the first inch of runoff to infiltrate into the soil substrate. 3. While visual) integrated retaining walls are referred and may be required, a building ad may be constructed using the cut and fill slopes as approved b 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; Y 8 8 P Y Q 8P Y 8 P PP Y P Y B p P 8 q 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 I inch of runotfwithout 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 runoffleaving 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 StormwaterBMP 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 I inch ofrunoffand is gradually released over the next 2 to 5 days. 6. Grading or construction access will not be permitted outside the Building Envelope and driveway unless approved by the ARC. 7. 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. 4.1 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 often 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. An such chemicals used or lied more than thin 30 feet from an lake or and shall be used or lied so as to prevent the spread or dissemination of such chemicals into the stream or downstream lake or pond. V applied Y( I Y P PP P P 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 Requirements 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 art of thea approval for the construction ofimprovements rovements of the Lot. P P PP P 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 8 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 ofstreet zone landscape area. At a minimum each front and shall have four 4 6"call er trees. Trees should be planted to provide shade screen and soften wall surfaces and accent the architecture of the residence. pp p p 4 p Y () p p p , 5. Shrubs and round covers shall be planted in adequate quantities to soften the transition from building to round accent courtyard walls provide accent and color at entry paths, and soften walls or large areas of avin . Shrubs and round covers should be planted in leasin row in s that are in harmony with the irrespective growth characteristics. P q Q 8 8.P rYP g P g 8 P P 88 P 8 Y P 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. Natives 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 and requirements. Other mature trees specimens can be substituted or added to reduce the shrub planting requirements. P P 8 P ( I P Y q P P 8 q 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. Similargrading, 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 1 to areas located within designated Common Areas or The Natural Area. P apply 8 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 q 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: 1. 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 (I) 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 (I) 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 forgrade changes in place of retaining walls. Native wash or creek areas should remain in their natural state. Additional accent elements ofgentle 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. 5.1 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 top rotect 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 fencingto dripline is not possible, protect trunk b strapping not nailing) a continuous shield of wood 2"x4"x5' around the trunk and la plywood on round in dripline of tree to prevent compaction of soil b trucks or machinery. p p .p Y pp 8( 8) ( ) YPY 8 p p P Y V 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 lotgrading 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 drain a shall be directed at least 10 feet away from foundation walls. 8 Y 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. pp l q p 8 Y 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.

For disconnected roofs, a maximum of 300 square feet of roofshall 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 ma be increased to 500 square feet. The receiving vegetated area shall be a rectangle of either 6 b 12 feet or 12 b 24 feet width of vegetated area b length of run indirection of flow). The entire rectangle shall not include an impervious 8 8 p 8Y q 8 8 8 Y Y ( 8 Y 8 ) 8 Y p 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. p Yp 2. For disconnected pavement, the receiving vegetated area shall be either 10 or 15 feet long. The maximum width ofpavement run that may discharge to the vegetated area is 100 feet and the maximum slope of the pavement shall be 7 percent. P. 8 8 8 P Y 8 8 P P 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. S. 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. Table 24-1.
