Purcellville City Zoning Code

ARTICLE 5

- LANDSCAPING, BUFFERS, SCREENING, FENCING, AND OPEN SPACE

Sec. 5.1.- Purpose and intent.

The preservation of existing trees and vegetation, as well as the planting of new vegetation, can significantly add to the quality of the physical environment of the community. The regulations outlined herein are designed to:

(1)

Preserve and promote the general health, safety and welfare of town citizens;

(2)

Respect and preserve the natural environment and protect Purcellville's historical, cultural and natural resources as outlined in the town's comprehensive plan;

(3)

Facilitate the creation of an attractive environment;

(4)

Provide a screen or barrier between dissimilar zoning districts which will minimize harmful impacts of noise, dust and other debris, glare from motor vehicle lights and other artificial sources of light, and other objectionable activities or impacts conducted on or caused by an adjoining or nearby dissimilar zoning districts;

(5)

Conserve natural resources and the benefits they provide including the protection of ground and surface water quality and air quality; the mitigation of flooding hazards; the stabilization of soil and the control of erosion and storm water runoff; the protection of sensitive areas; the absorption carbon dioxide and the supply of oxygen, an essential ecological function; and the provision of a haven for birds, which in turn assist in the control of insects;

(6)

Separate vehicular and pedestrian areas while providing opportunities for visual surveillance between these areas;

(7)

Provide shade and provide a buffer against noise and glare;

(8)

Preserve properties and their values; and

(9)

Encourage appropriate uses of land.

Sec. 5.2. - Applicability.

The provisions of this article shall apply to all site development plans and subdivision construction plans within the corporate limits approved after the effective date of this ordinance including those which include the reconstruction and enlargement of existing structures. This article does apply to the enlargement of any parking lot, but does not apply to the resurfacing of any existing lot. This article shall apply to the construction of any parking lot with ten or more parking spaces and the construction, extension or widening of any public or private street.

Sec. 5.3. - Flexibility in administration.

Because of the wide variety of developments, the relationships between them, and the lots upon which they are built, it is neither possible nor prudent to establish inflexible landscaping and buffering requirements. Therefore, credits and/or modifications satisfying the purpose and intent of this article and each section of this article may be permitted. Credits are contained in Subsection 5.7.3.

Modifications are contained in Subsection 5.9.8 and Subsection 5.12.7.

Sec. 5.4. - Landscape plan required.

A landscape plan meeting the requirements of this article is required for all subdivision construction plan and site development plan applications.

(1)

In any commercial or industrial district, or in the common open space of any residential development, when no subdivision or site development plan is sought, any person proposing to remove or destroy any live, healthy tree which is four inches or greater diameter at breast height (DBH), shall first submit, for approval by the zoning administrator, with advice from the tree and beautification commission, or its designee, a plat showing the location of the trees proposed to be removed and photographs of the trees. The tree and beautification commission or its designee can employ, at its discretion and at the applicant's expense, an arborist for the purpose of determining if the tree or trees in question are live and healthy.

(2)

Contents of landscape plan. All landscape plans shall be prepared as follows:

(a)

For lots of less than 1.15 acres, every landscape plan required by this article shall be prepared by a landscape architect, landscape designer, nurseryman, or other individual with professional experience in landscaping. For lots of 1.15 acres or more, every landscape plan required by this article shall be prepared and certified by a landscape architect, engineer, landscape designer or landscape contractor.

(b)

Scale. Plans shall be drawn to a scale of not less than 30 feet to the inch.

(c)

Site analysis. A site analysis is required as part of the landscape plan for any site of three acres or more. A site analysis shall, by plan and narrative, address all existing site features, including, but not limited to, existing trees of four inches diameter at breast height (DBH); their driplines; species; specimen trees, heritage trees or memorial trees, as defined in this ordinance and Section 86-22 of this Code; proposed tree preservation areas; centerline and banks of streams; riparian habitat; any rare or threatened plant or animal species identified by state or federal agencies; stream buffers; topography; sensitive areas such as steep slopes, wetlands and floodplain; existing and proposed easements; historic features; other structures; utilities; rare and endangered plant species present; and rare and endangered animal species present or occasionally present.

(d)

Proposed development. All plans shall illustrate with sufficient detail the location of all proposed construction including the limits of clearing and grading, driveways, parking areas, curbs, sidewalks, utility lines, structures and landscape areas. Landscape areas shall indicate dimensions, and all proposed trees and plants shall be illustrated at installation size.

(e)

Existing vegetation. All plans shall show:

i.

The location, size, and species of all trees which are at least six inches in DBH;

ii.

A designation indicating whether each of these trees is to be preserved or removed;

iii.

For trees designated for preservation, specifications for their protection during construction, per the tree preservation and protection requirements of Section 2.5 of this article;

iv.

Proposed grade changes or other potentially injurious work within the dripline of trees designated for preservation with specifications for maintaining ground drainage and aeration around such trees; and

v.

Other information that the zoning administrator deems essential.

(f)

Schedule. All plans shall be accompanied by a schedule of plants proposed, including a key, the number proposed, their height, caliper or gallon size, common name, botanical name, and cultivar.

(g)

Calculations. All landscape plans shall include a table calculating the amount of open space, landscape area, and number of plants required by the zoning ordinance and the amount of open space, landscape area, and number of plants provided. Where fractional requirements result, the vegetation and/or area required shall be construed to be the next highest whole number.

(h)

Review procedures. The zoning administrator shall be responsible for the review of all landscape plans. All landscape plans shall be reviewed using the same procedure as the site development plan or subdivision construction plan that they accompany.

Sec. 5.5. - Special use permits.

In addition to the landscape requirements of this article, the planning commission and town council may impose further landscaping requirements as a condition of granting any special use permit in order to ensure compatibility of the site with surrounding properties.

Sec. 5.6. - Required landscaping, buffering and open space areas.

Nothing in this article shall prohibit an owner/applicant from providing more than the required minimum landscaping, buffering and open space areas set forth below.

(1)

Required minimum landscaping, buffering and open space areas.

(a)

Parcels of two acres or less: The total of all landscaping, buffering and open space areas shall be a minimum of 15 percent of the subject parcel.

(b)

Parcels greater than two acres and less than six acres: The total of all landscaping, buffering and open space areas shall be a minimum of 20 percent of the subject parcel.

(c)

Parcels of six acres or greater: The total of all landscaping, buffering and open space areas shall be a minimum of 25 percent of the subject parcel.

(2)

Reductions. In any circumstance where the required landscaping, buffering and open space areas would together exceed the required minimums set forth in section 1.9 above, such landscaping, buffering and open space areas may be reduced in the following order:

(a)

Interior parking lot landscape areas.

(b)

Perimeter parking lot landscape areas.

(c)

Buffer yards.

(3)

Parcels of two acres and greater. Notwithstanding the above, the zoning administrator shall have the authority to require that the landscaping area reductions and buffer yard reductions occur in a manner that best meets the purposes and intents of this article and each of its sections.

Sec. 5.7.1. - Purpose and intent.

The preservation of existing vegetation and sensitive resource areas can significantly add to the quality of the physical environment of the community. The purpose of resource management is to:

(1)

Preserve and promote the general health, safety, and welfare of town citizens;

(2)

Further the objectives of the town's comprehensive plan;

(3)

Provide shade and provide for useful and attractive open spaces;

(4)

Conserve natural resources and the benefits they provide, including the protection of ground and surface water quality and air quality; the mitigation of flooding hazards; the stabilization of soil and the control of erosion and storm water runoff; the absorption of carbon dioxide and the supply of oxygen, an essential ecological function; and the provision of a haven for birds, which in turn assists in the control of insects;

(5)

Preserve properties and their values; and

(6)

Encourage appropriate uses of land.

Sec. 5.7.2. - Applicability.

Resource management is required in conjunction with all landscape plans required by Section 1.4 of this article.

Sec. 5.7.3. - Credit for existing vegetation.

(1)

Vegetated areas. Any healthy existing vegetated area proposed to be saved, which complies with the intention of Section 5.9: Buffering requirements, of this article, shall be deemed to meet buffering requirements for the entire length of the existing vegetated area.

(2)

Hedgerows. Healthy hedgerows at least three feet in height preserved at property boundaries may be used to meet or partially meet the requirements of screening as required by Section 5.9: Buffering requirements, of this article.

(3)

Canopy trees. Existing canopy trees preserved on-site may be used to satisfy the requirements for parking lot landscaping, street tree plantings, and screening required by Section 5.12, Subsection 5.8.3 and Section 5.14 of this article. Any existing trees used to meet the requirements of the ordinance must be of a species deemed acceptable by the zoning administrator, in consultation with the tree and beautification commission, or its designee; at least four inches DBH; in healthy condition; and be protected from construction activity. Such protection procedures shall follow the requirements of Subsection 5.7.5: Tree preservation and protection measures, of this article.

(4)

Ornamental trees. Existing ornamental trees preserved on-site may be used to satisfy the requirements for parking lot landscaping, street tree plantings, and screening required by Section 5.12, Subsection 5.8.3, and Section 5.14 of this article. Any existing ornamental trees used to meet the requirements of the ordinance must be of a species on the Purcellville Tree and Shrub List ("plant list") prepared by the tree and beautification commission, or as deemed acceptable by the zoning administrator; at least ten feet in height; in healthy condition; and be protected from construction activity. Such protection procedures shall follow the requirements of Subsection 5.7.5: Tree preservation and protection measures, of this article.

(5)

Exceptional trees. Preservation of designated heritage, specimen or memorial trees or trees of exceptional size or age may be credited as four trees for the purposes of this article, as approved by the zoning administrator, if the entire area under the dripline of the exceptional tree(s) is preserved in a manner satisfactory with the tree and beautification commission or its designee, and in conformance to Subsection 5.7.5: Tree preservation and protection measures, of this article. These credits may be used to satisfy the requirements for parking lot landscaping, street tree plantings, and screening contained in Section 5.12, Subsection 5.8.3, and Section 5.14 of this article. Any exceptional trees used to meet the requirements of the ordinance must be in healthy condition, as determined by the zoning administrator, in consultation with the tree and beautification commission or its designee. Trees of exceptional size and canopy are those determined by the zoning administrator to be within 25 percent of the State Champion rating. Exceptional age is defined as 150 years old or greater.

Sec. 5.7.4. - Removal of existing trees.

Existing tree cover, particularly mature trees, or trees on the plant list, shall be preserved to the fullest extent possible and considered in the design of grading and improvements on a property. However, it is acceptable to remove existing trees that are invasive, in poor health and jeopardize the health and viability of surrounding healthy trees, or interfere with public utilities provided that justification is given on the landscape plan. The following criteria shall be used in determining whether to approve or disapprove tree removal:

(1)

The intended use of the property and feasible alternatives which would preserve existing trees;

(2)

The consistency of the proposed action, including changes in the topography and proposed landscaping, with the purposes of this article;

(3)

Status as a designated heritage, specimen or memorial tree;

(4)

Good horticultural and forestry practices, including a consideration of the health of each individual tree;

(5)

The hardship imposed or the reasonable use denied to the applicant as a result of disapproval;

(6)

The impact of such action on surrounding property or persons; and

(7)

Environmental objectives such as protection of sensitive areas, stream bank stabilization, flood control, erosion and sedimentation control, and the deadening and absorption of sound.

Sec. 5.7.5. - Tree preservation and protection measures.

(1)

Purpose. Trees establish their roots in areas which supply them with sufficient nutrients, water, and oxygen. These root masses maintain the balance between intake of water from the soil and the loss of water through transpiration. Disturbing this relationship between the soil and the roots can damage or kill a tree. Refer to Virginia Erosion & Sediment Control Handbook, Chapter 3, Tree Preservation & Protection Standards and Specifications, for additional information and guidelines.

(2)

Disturbance within the dripline. No excavation, embankment, or other subsurface disturbance shall be taken within a distance equal to a vertical (drip) line extending from the outermost edge of the tree's canopy to the ground. No impervious surface may be located within 12.5 feet of any tree to be retained, unless specific techniques are used to ensure survivability of the tree. When retaining existing trees near a parking lot or accessway, sufficient ground 1.5 times the diameter of the dripline shall be left ungraded around each tree. No specimen or heritage tree that is to be saved shall have more than 25 percent of the area enclosed by a circle two times the diameter of the dripline disturbed by trenching, excavating, or foundations. Finished grade within an area 1.5 times the diameter of the dripline of trees to be saved shall not be six inches higher or lower than the existing ground elevation unless specific alternatives for tree preservation are approved by the zoning administrator.

(3)

Physical measures. During development or razing activity, the contractor shall install effective dripline protection around all trees to be preserved, and shall further install tree wells, retaining walls or other structures necessary to protect individual trees designated to be preserved. Such protective measures shall be specified on the landscape plan and shall be designed and installed in a manner consistent with good arboricultural practices. These protective measures shall not be removed without the consent of the zoning administrator. If the zoning administrator finds that these protective measures are insufficient to protect the vegetation being preserved on the site, additional protective devices, as specified by the zoning administrator, shall be installed to ensure adequate protection. To further ensure the survival of trees designated to be preserved, the property owner or his agent shall provide such surety as required in Subsection 5.10.7: Monitoring and enforcement, of this article.

(4)

Damage or destruction of trees to be preserved. In the event one or more trees of six inches DBH or greater which are designated to be preserved under Section 5.7, Resource management, of this article are destroyed or, in the opinion of the zoning administrator, are significantly damaged during clearing or construction activities, or are willfully destroyed, injured, or removed, or if the tree dies within five years, the property owner shall replace such trees with one large tree four inches in caliper and one small tree six to eight feet in height for every 300 square feet of canopy area destroyed.

(5)

Reduction of parking. If the preservation of trees involves an area that would otherwise be devoted to required parking and as a result the provisions of required parking cannot be followed, the number of parking spaces required may be reduced by up to 15 percent.

Sec. 5.8.1. - Purpose and intent.

The planting of new trees in public spaces can significantly add to the quality of the physical environment of the community. The purpose of streetscaping is to:

(1)

Preserve and promote the general health, safety, and welfare of town citizens;

(2)

Respect and preserve the natural environment and protect Purcellville's historical, cultural and natural resources as outlined in the town's comprehensive plan;

(3)

Separate vehicular and pedestrian areas while providing opportunities for visual surveillance between these areas;

(4)

Provide shade and facilitate the creation of an attractive environment;

(5)

Preserve properties and their values;

(6)

Conserve natural resources and the benefits they provide, including the protection of ground and surface water quality and air quality; the stabilization of soil and the control of erosion and storm water runoff; the absorption of carbon dioxide and the supply of oxygen, an essential ecological function; and the provision of a haven for birds, which in turn assists in the control of insects.

Sec. 5.8.2. - Applicability.

Streetscaping is required along all public and private street frontages. In general, along public streets, street trees shall be planted in the public right-of-way and maintenance of these trees after the warranty period of 18 months from the time of planting or after release of any applicable maintenance bond, whichever is later, shall be the responsibility of the Town of Purcellville.

Sec. 5.8.3. - Streetscaping standards.

(1)

Species. Tree species shall conform to those identified as street trees in the plant list maintained by the tree and beautification commission. Substitutions may be approved by the zoning administrator, in consultation with the tree and beautification commission, or its designee. All street tree plantings must be approved by the zoning administrator. In reviewing plans for street tree plantings, the zoning administrator shall consider:

(a)

The size, type and condition of existing street trees;

(b)

The adopted design study, landscape plan or design theme for the street;

(c)

Street trees should be located to provide shade and visual relief; and

(d)

Flowering ornamental trees should be planted in groups.

(2)

Number. One medium or large canopy tree for every 40 feet of street frontage. For the purposes of this subsection, "medium canopy tree" refers to a deciduous tree that reaches a maximum height of 35 to 45 feet at full maturity and "large canopy tree" refers to a deciduous tree that exceeds 45 feet at maturity.

(3)

Location. In commercial zoning districts all street trees shall be located in the required landscape area adjacent to the street; provided, however, if trees are planted in paved pedestrian areas, they shall be planted in tree wells that include a planting grate, with approved structural soil, and the minimum width of the adjacent pedestrian area shall be three feet. In residential zoning districts street trees shall be located generally within 15 feet of the right-of-way. Nothing in this section shall be construed to require tree plantings at even intervals.

(4)

Overlapping requirements. Where the requirements of the various sections of this article overlap, vegetation planted to meet the requirements of this section shall also count towards the requirements of Section 5.9 and Subsection 5.12.4 of this article.

Sec. 5.9.1. - Purpose and intent.

The purpose of buffering is to provide a screen or barrier between dissimilar zoning districts which will minimize harmful impacts of noise, dust and other debris, glare from motor vehicle lights and other artificial sources of light, and other objectionable activities or impacts conducted on or caused by an adjoining or nearby dissimilar zoning districts.

Sec. 5.9.2. - Applicability.

(1)

The requirements of this section shall apply to all new construction and all reconstruction or enlargement of existing structures constituting more than 50 percent of the floor area of the existing structure(s). Buffering requirements shall only apply to that portion of the site directly affected by the proposed improvements, or changes. When a conflict exists between this paragraph and Paragraphs (2) and/or (3) below, the limitations of this paragraph shall apply.

(2)

Buffering shall be required along those portions of the perimeter of any lot in any zoning district abutting a zoning district of dissimilar intensity, pursuant to Subsection 5.9.4: Buffering matrix, of this article. This may be accomplished through land, architectural means, and/or vegetative materials.

(3)

When a public right-of-way separates dissimilar zoning districts, buffering shall be required pursuant to Subsection 5.9.4: Buffering matrix, of this article, but credit shall be given for the width of the public right-of-way, pursuant to Subsection 5.9.8(4): Buffering adjoining streets, of this article.

(4)

Buffering shall be required in specific instances, as set forth in Subsection 5.9.5 through Subsection 5.9.7 of this article.

Sec. 5.9.3. - Bufferyards and screening.

TABLE A—BUFFER AND SCREENING DEFINITIONS
Buffer yard Continuous land area provided to create a definite spatial separation between adjoining dissimilar zoning districts. Buffer yards are of differing widths, pursuant to Subsection 5.9.4: Buffering matrix, of this article, are located between uses in adjoining dissimilar zoning districts and may contain vegetative and/or architectural components that achieve the purpose of buffering pursuant to Subsection 5.9.2: Applicability, of this article. Buffer yards do not contain active recreational uses, the storage of materials, buildings, parking or loading areas for motor vehicles or equipment, or signs. The width of buffer yards is measured on a horizontal plane.
Buffering Consists of buffer yard and/or screening. Buffering is provided to block views and create a definite spatial separation between adjoining dissimilar zoning districts, to achieve the purpose of screening as stated in Subsection 5.9.2: Applicability, of this article.
Screening A massing of vegetation and/or architectural components provided to block views and create a definite visual separation between adjoining dissimilar zoning districts, such that it achieves the purpose of screening pursuant to Subsection 5.9.1: Purpose and intent, of this article. Screening is placed within buffer yards. Screening shall be placed to minimize interference with visibility for all modes of transportation. There are two types of screening:
Screening 1. (S1) A semi-opaque screening partially blocking views and creating a limited visual separation between adjoining properties.
Screening 2. (S2) An opaque screening completely blocking views and creating a definite visual separation between adjoining properties.
Architectural components Walls and other structural elements acceptable to the board of architectural review for the purpose intended.
Relationship to setbacks Buffer yards may be provided in the area required for setbacks by the zoning district regulations, except in residential zoning districts. Buffer yards in residential zoning districts must be provided in common open space.
Relationship to other landscape requirements Where the requirements of the various sections of this article overlap, the buffering required by this section shall also count towards the perimeter parking lot landscaping requirements of Section 5.12, and may count towards parking lot interior landscaping, as described in Subsection 5.12.6: Location of interior parking lot landscaping area, of this article.
Bufferyards exceeding setbacks In any instance, when the buffer yard required by this article exceeds the setback required by the zoning district regulations, the buffer yard required by this article must be provided.
Permitted encroachments Driveway, entrances, sidewalks, trails, interparcel connectors, and parking lots combined across lot lines may encroach into the required buffer yard. Encroaching driveways, entrances, and interparcel connectors shall run substantially perpendicular to the buffer yard. Screening displaced by such features of a width of 24 feet or less does not have to be relocated, but can be removed from the landscape plan.
Plant varieties Plantings must be identified as suitable buffer plants in the plant list. Alternative varieties may be approved by the zoning administrator, in consultation with the tree and beautification commission, or its designee.
Construction of walls Where the developer chooses to construct a four-foot high architectural screen of a design and materials acceptable to the board of architectural review, screening and buffer yard requirements may be reduced by as much as two-thirds, as determined by the zoning administrator, with consultation from the tree and beautification commission, or its designee, for that portion of the site affected by the architectural screen.
Screening requirement For maximum flexibility in screening requirements, the zoning administrator, with consultation from the tree and beautification commission, or its designee, shall determine if a proposed screen meets the requirements of Subsection 5.9.3(1)(b): Screening, and Subsection 5.9.4: Buffering matrix. Vegetation shall be spaced at a minimum as required in Subsection 5.10.6: Minimum plant spacing.
Properties or residential subdivisions with split zoning Where properties or proposed residential subdivisions contain two or more zoning districts, any buffer yard that is required between those zoning districts does not have to be provided along the zoning district boundary, but instead can be provided along the property or subdivision boundary in a location designated by the zoning administrator.

 

Sec. 5.9.4. - Buffering matrix.

The buffering matrix below describes the requirements for screening and buffer yards between adjoining dissimilar zoning districts. The buffering required of each property is identified in the buffering matrix below. This matrix references Subsection 5.9.3.: Screening requirement, of this article. County zoning districts adjoining the town are included in the matrix.

Sec. 5.9.5. - Buffering of outdoor storage lots, loading areas, and the like.

(1)

Buffer yard. A 20-foot-wide buffer yard shall be located where necessary to accommodate the screening required in Subsection (2) below. Where buffer yard requirements overlap, the buffer yard required by this section shall count towards the buffer yard requirement of Section 5.9.4: Buffering matrix, of this article.

(2)

Screening. All outdoor storage, loading areas, contractor yards, areas for refuse and recycling, and the like, created after the adoption of this ordinance shall be screened from all public streets and adjacent residential properties. An opaque screen at least six feet in height comprised of plants, trees, walls or other opaque materials must be provided.

Sec. 5.9.6. - Buffering along the Washington and Old Dominion Trail.

(1)

Buffer yard. For residential sites developed adjacent to the W&OD Trail, a 30-foot buffer yard shall be required along that portion of the site which abuts the trail. Where buffer yard requirements overlap, the buffer yard required by this section shall count towards the buffer yard requirement of section Subsection 5.9.4: Buffering matrix, of this article.

(2)

Screening. Screens provided within the required 30-foot buffer yard adjacent to the trail shall meet the Screen 2 requirements as defined in Section 5.9.3 of this article.

Sec. 5.9.7. - County adjoiners.

When the subject property adjoins a property in the county, the zoning administrator shall determine the specific buffer yard and screening requirements along that property line, if any, after consideration of the zoning designation of the adjoining property.

Sec. 5.9.8. - Modifications of buffering requirements.

The requirements of Section 5.9: Buffering requirements, of this article shall be applied equally to all similarly situated properties. Modifications to these standards may be granted in writing by the zoning administrator in any of the following circumstances:

(1)

Varied topography. The zoning administrator may waive or modify the requirements of Section 5.9: Buffering requirements, of this article, if the required buffering would be ineffective at maturity due to the proposed topography of the site, the existing topography of adjacent sites, and/or the location of the improvements on the site.

(2)

Proposed buffering on adjoining property. Buffering may be placed on adjoining property within a buffer yard easement of the width required in the buffering matrix, Section 5.9.4 of this article. This buffering shall be in addition to the buffering required of the adjoining property owner.

(3)

Alternative screens. Alternative planting programs achieving the objectives of the required buffering are permitted to allow creativity and flexibility in landscape design. Alternative planting programs are permitted with the approval of the zoning administrator if the applicant can demonstrate that screening objectives have been met through the use of hedges, shrubs, walls, fences, berms, and/or topography.

(4)

Buffering adjoining streets. The buffer yard and screening requirements of Section 5.9.4: Buffering matrix, of this article, can be reduced when a public right-of-way separates dissimilar zoning districts. Modifications shall be given only on the side adjacent to the public right-of-way, as follows:

TABLE C—BUFFER REDUCTION FOR ADJOINING STREETS
Right-of-way widthBuffer yard and screening
20' S130' S250' S2
Less than 40' Reduce by 50% Reduce by 33% Reduce by 25%
40' to less than 50' Reduce by 75% Reduce by 50% Reduce by 50%
50' and greater Reduce by 100% Reduce by 100% Reduce by 100%

 

(5)

Development in planned development districts. The planning commission may modify or reduce the requirements for buffering for planned developments.

(6)

Properties with nonconforming buffering and/or structures built prior to adoption of this article. The buffering requirements of this article may be waived or reduced when the zoning administrator finds that the required screening would serve no useful purpose or that a suitable screening alternative has been provided in the opinion of the zoning administrator.

Sec. 5.10.1. - Utilities and easements.

The following is the procedure for coordinating landscaping, buffering, utility easements, and underground pipelines:

(1)

General.

(a)

Private and public easements are allowed within ordinance-required buffer yards.

(b)

Ordinance-required landscaping materials are allowed in private easements, unless specifically prohibited by the easement. If, in the opinion of the town attorney, the easement deed is unclear as to whether or not the deed grants permission to place screening in the easement, screening will be permitted in the easement only by written permission of the easement holder which irrevocably grants permission to the owner and its successors and assigns to place screening in the easement area and which specifically addresses who shall be responsible for replacement of the screening should it be damaged by the easement holder through the exercise of its easement rights.

(c)

Ordinance-required landscaping materials, excluding trees, are permitted in public easements to be owned by the Town of Purcellville. Trees may be permitted in town easements by special approval as provided in Paragraphs (2) and (3) below.

(2)

Alternatives. Prior to requesting special approval to locate ordinance-required trees in a town utility easement, the following must be considered in the order shown below:

(a)

Relocate proposed town utility lines outside of the landscape area, if possible.

(b)

Move trees outside of easements if objectives of ordinance-required buffering are met.

(c)

Design required landscaping for screening using shrubbery only (no trees) within public easements.

(d)

If, in the opinion of the zoning administrator, any of the three alternatives considered in the order listed above can resolve to conflict between tree locations and utility easements, then no special approval is necessary.

(3)

Special approval. Special approval from the director of public works to locate ordinance-required trees in a town easement may be authorized if the following are met:

(a)

All options in Paragraph (2): Alternatives, of this subsection, have been fully investigated and do not resolve the location of proposed trees.

(b)

Tree species selected for placement within a public easement must be a type which obviates the effect of the root system upon the pipeline.

(c)

Trees shall not be placed directly over top of an underground pipeline. Trees must be placed as far as possible from the underground pipeline.

Sec. 5.10.2. - Overhead utility lines.

Where street trees, canopy trees or evergreen trees are required near or under existing overhead utility lines, both the guidelines and plant list contained in Virginia Cooperative Extension Service Publication 430-029 shall be used to guide plant location and species selection. Where necessary, ornamental trees can be substituted for canopy trees and smaller evergreen tree species can be selected. With the exception of any species prohibited by the plant list and the exception of species unsuitable for the Purcellville area, species to be planted near or under overhead utility lines shall be selected from Publication 430-029.

Sec. 5.10.3. - Minimum specifications for plant materials.

(1)

Condition. All plants required by this article shall be well branched and well formed, sound, vigorous, healthy, and free from disease, sunscald, windburn, abrasion and harmful insects or insect eggs and shall have healthy, normal and unbroken root systems. All plants shall comply with the American Association of Nurserymen's Standards and/or American Standard for Nursery Stock, American Nursery & Landscape Association, ANSI Z60.1-2004 and shall conform to the representative species.

(2)

Size. All plant material installed to meet the requirements of this ordinance shall comply with the minimum size requirements below at the time of planting:

(a)

(3)

CPTED—Crime prevention through environmental design. The requirements of this section may be modified if the zoning administrator finds that such modification is required to meet one or more CPTED principles as suggested by the Purcellville Police Department.

Sec. 5.13.1. - Purpose and intent.

The stream and creek buffer is established to govern the construction of buildings, structures, parking, and other impervious surfaces in areas adjacent to major stream areas draining greater than 640 acres and minor stream areas draining less than 640 acres, but more than 100 acres by providing for a setback area from the channel scar line in which construction of improvements would not occur except as set forth below. These streams and creeks within the Town of Purcellville corporate limits include, but are not limited to, the South Fork of Catoctin Creek, North Fork of Goose Creek and Crooked Run, as shown on the Town of Purcellville "Major & Minor Floodplains - Purcellville and JLMA" map.

The intent is to:

(1)

Promote water quality and the preservation of significant environmental resource areas, wildlife habitat and corridors, and native vegetation areas;

(2)

Protect and enhance water and groundwater recharge processes by protection of the natural capacity of vegetative areas along rivers and creeks to filter and purify stormwater runoff;

(3)

Protect aquatic environments from the warming effects of solar radiation by preserving riparian tree canopy cover;

(4)

Promote tourism and high quality corporate investment by maintaining to the extent reasonably possible, existing high water quality;

(5)

To maintain the scenic beauty of the streams of Loudoun County; and

(6)

Implement the comprehensive plan.

Sec. 5.13.2. - Stream and creek buffer established.

The following setbacks are established along major and minor streams and creeks in areas where the 100-year floodplain is less than the setbacks provided below:

(1)

Major stream buffer. For streams with major floodplains (streams where the watershed is greater than 640 acres): A minimum of 100 feet on each side of the creek measured from the channel scar line of each creek or stream.

(2)

Within the 100-foot buffer, a streamside forested area of at least 25 feet on each side of the creek or stream shall be provided. The streamside forested area shall consist of mature trees where they exist prior to the development of a property and shall be supplemented with new tree plantings if required by the town. When no mature trees exist, the streamside forested area shall be created with new tree plantings. All new tree plantings shall comply with the minimum size requirements for plantings found in Article 5 of this ordinance. New tree plantings shall be of a species compatible with the stream, creek, and/or wetlands. Unless otherwise exempted by this ordinance, land uses permitted within the streamside forested area shall be limited to pedestrian footpaths (preferably constructed of a porous material); well-designed watercourse crossings, designed in accordance with accepted best management practices; passive recreation areas such as gazebos or benches; and other such uses, as determined by the zoning administrator, which do not negatively impact the adjoining stream, creek, or wetlands.

(3)

Minor stream buffer. For streams with minor floodplains (streams with a watershed of less than 640 acres, but greater than 100 acres): A minimum of 35 feet on each side of the stream or creek measured from the channel scar line of the stream or creek.

(4)

Where wetlands exist adjacent to a major or minor stream buffer, a setback of at least 35 feet shall be maintained from all wetlands for all structures and impervious surfaces. When any part of this ordinance requires a setback of more than 35 feet, the larger setbacks shall be provided.

Sec. 5.13.3. - Effect of buffer.

The construction of buildings, structures, impervious parking lots, or other impermeable surfaces within the stream and creek buffer is prohibited, except as stated herein. Existing buildings and structures within the stream and creek buffer are not considered nonconforming, i.e., they can be added to and, if destroyed by fire or casualty, they can be rebuilt to the same or an equivalent footprint. The town encourages the growth, through plantings or natural succession, of vegetative and forestall cover within the Scenic Creek Buffer area.

Sec. 5.13.4. - Development criteria.

The stream and creek buffer are not intended to, and shall not, limit development density (gross floor area or units per acre) otherwise allowed on land within the stream and creek buffer area, and off-street parking requirements shall be reduced as necessary to accommodate the buffer without limiting such otherwise permitted development. The stream and creek buffer shall be administered like any other setback provided for in this ordinance in allowing otherwise developable land within the setback area to be counted for density computation purposes and applied toward the construction of improvements outside the setback area.

Sec. 5.13.5. - Exceptions.

Public utility installations, road crossings and driveways shall be permitted subject to applicable federal and state regulations, to this ordinance, and to such performance standards as may be contained in the facilities standards manual.

Except when fences are required by this zoning ordinance for screening, a fence shall not exceed heights indicated in Table D of this section. When required by other provisions of this zoning ordinance for screening, a fence shall be a minimum of six feet in height.

(2)

Fence height at a given location along a fence line shall be the difference in elevation between the grade at the base of the fence and the top of the fence at that location. The grade at the base of the fence shall be the elevation of the ground surface before mounding or building-up of the ground surface, if any, occurred. If a fence occurs along a terraced portion of earth, such as a retaining wall, its height is measured from the higher ground elevation.

(3)

No fences greater than three feet in height shall be installed in the clear visibility triangle.

(4)

Fence maintenance. All fences shall be maintained and in a safe and upright condition.

(5)

All fences shall be installed so that, when a fence has a "finished" or "clean" side, that side faces outward, toward adjacent lots; and the "unfinished" or "bad" side faces the interior of the lot. When a fence is installed on the property boundary between two lots, the "unfinished" or "bad" side shall face the lot of the landowner who is installing the fence.

(6)

All swimming pools, hot tubs, and retention ponds shall be located on portions of a lot that is completely enclosed by a fence of at least four feet in height.

TABLE D—FENCE HEIGHT BY LOCATION
FENCE LOCATIONFENCE HEIGHT
Front Yard 4 feet maximum
Side Yard Six feet maximum; fences of more than four feet in height in the side yard may not be extended closer to the street right-of-way than the front-facing elevation of any principal structure on the subject lot or an adjacent lot.
Rear Yard 6 feet maximum
