The following provisions to protect public trees and provide protective regulations governing planting and removal of unsafe vegetation shall apply to all persons, including natural persons, independent contractors, public utility companies, public works and other town departments: (a) Trees endangered by excavation or construction. In the absence of a written waiver by the town arborist, any public tree located within 20 feet of any proposed (i) excavation, or (ii) construction of a building or other structure, or (iii) street work shall have its critical root zone protected from all building material, dirt or other debris which might be generated by the operation concerned. To accomplish such protection, the town arborist shall submit written instructions and the party responsible for the excavation, construction or work shall, in advance of commencing the operation, comply with such instructions by erecting a substantial fence, frame, shield or box not less than three feet high at a location calculated to protect the tree's critical root zone. (b) Trees endangered by public works and other ditches. Without prior notification of and discussion with the town arborist and strict adherence to the town arborist's instructions relative to tree protection, no person shall change the natural grade, excavate any ditches, tunnels, trenches, or lay any line, within ten feet of the critical root zone of any tree in any public area. Provided that (i) the town arborist is notified as soon as practical after the work is done and (ii) the particular operation would not increase the existing utilities beyond their original capacity, the provisions of subsection (b) shall not apply to any person performing emergency work to restore existing underground utilities within the same trench. (c) Trees put at risk by placement of materials on public property. No person shall deposit, place, store or maintain upon any public place any stone, brick, sand, concrete or other materials that might impede the free passage of air, water or fertilizer to the roots of any public tree. (d) Distance of certain trees from public sewers. Poplar, willow, American elm or cottonwood trees planted anywhere in the town after the effective date of this ordinance shall be placed at least 100 feet away from public sewers. (e) Planting in park or in or near public right-of-way. (1) Shade or ornamental trees. No shade or ornamental tree or shrub shall be planted in any public right-of-way or within five feet of such right-of-way or in any public park until such tree or shrub shall have first been approved and the place where it is to be planted designated by the town manager and a permit granted therefore. (2) Prohibited species. It shall be unlawful for any person to plant in any park or public right-of-way or within five feet of such right-of-way line the following trees: poplar, willow, cottonwood, fruit trees (except ornamental types), nut trees (except oak and hickory), ailanthus, mountain ash, mimosa, silver maple, American elm and sycamore maple. (f) Attaching rope, sign or other device. No person shall fasten any rope, wire, sign, poster, handbill or other device to a tree or shrub or to any guard about such tree or shrub on a public right-of-way or in a park. (g) Wires in right-of-way or park. (1) Protection of trees and shrubs. Every person having or maintaining any electric, telephone, telegraph or other wires running through a public right-of-way or park shall securely fasten and maintain such wires in such a manner as will safeguard the trees and shrubs against any damage therefrom and shall make periodic adjustments whenever necessary to prevent damage to trees and shrubs growing in any public right-of-way or park. (2) Consolidation. Persons having or maintaining any electric, telephone, telegraph or other wire running through a public right-of-way shall consolidate their wires so as to place as few poles as possible in the right-of-way and shall, whenever possible, place such poles in alleys, utility easements and along rear lot lines. (h) Trimming or cutting of overhanging trees. (1) The trimming or cutting of trees, the limbs of which overhang streets or sidewalks of the town, or trees located on the sidewalks or streets of the town, shall be done in the discretion and under the authority of the town manager and supervision of the town arborist. Such work shall be done in a proper manner with the least possible damage to the trees trimmed or cut. (2) Any person applying for the privilege of trimming or cutting trees to promote the efficiency of a public utility shall pay all expenses incident to such work. (3) It shall be unlawful for any owner of property adjacent to a street to obstruct or interfere with the cutting or trimming of trees under the provisions of subsection (h). (i) Vegetation impeding, etc., movement of vehicular or pedestrian traffic ? Generally. (1) Whenever it shall be determined by the department head of any department of the town that there is growing vegetation which impedes, hinders or makes unsafe the movement of either vehicular traffic or pedestrian traffic, the department head shall make a written report to the town manager, with copy to the town arborist, giving location and other pertinent information. Thereafter, the town arborist shall supervise any measures taken to correct the hazardous condition, as directed by the town manager. (2) The town manager shall forthwith notify the owner of the property where such vegetation exists and shall demand that the owner shall, within the space of ten days, either completely remove such vegetation or trim such vegetation to such an extent as to remove any hazard. Such notice shall be served personally on the owner of the property if he resides on the property or is a resident of the town; otherwise, such notice shall be served on the owner by registered or certified mail with provision made for a return receipt. If the property is rental property, a copy of such notice shall be served on one of the tenants occupying it. If the owner of the property is a nonresident of the state and has an agent within the state who collects the rents from the property or has control of the property, then service of the notice upon such agent shall constitute service upon the owner.

APPENDIX B ZONING ORDINANCE SECTION XIV: LANDSCAPING STANDARDS A. Purpose and goals. The purpose shall be to provide landscaping and buffering guidelines for developers and builders to follow in the design, installation, and maintenance of proposed high density residential, commercial and industrial development projects. The goal shall be to promote quality landscaping design throughout the city while integrating various elements of site design, preserving and enhancing the particular identity of the site, and creating a pleasing site character. Landscaping may include plant materials such as trees, shrubs, ground covers, perennials, and annuals, and other materials such as rocks, water, sculpture, art, walls, fences, paving materials, and street furniture. B. Applicability and exemptions. 1. Applicability: These requirements shall apply to: a. New principal building or use. Principal buildings or open spaces of land constructed, reconstructed, or established after the adoption of this ordinance. b. Changes in use which result in higher intensity use that may be deemed incompatible with abutting property or properties. c. Expansions. All expansions of buildings, parking areas, or open uses of land, except the first five hundred (500) square feet of expansion. 2. Exemptions: These requirements shall not apply to: a. Existing and proposed single-family detached dwellings or two-family dwellings on their own lots. b. Property lines abutting railroad rights-of-way and utility easements in excess of sixty (60) feet in width. c. Property lines abutting dedicated street right-of-way which has remained open for a period of at least fifteen (15) years. C. Landscape plan. A landscape plan shall be submitted with each site plan application, unless the zoning administrator determines the project is of a minor nature or would cause minimum impact on surrounding private or public facilities. The administrator may waive any or all of the landscape plan requirements. The plan shall identify: 1. Existing and proposed trees. 2. Shrubs and ground covers. 3. Natural features such as rock outcroppings. 4. Landscaping elements. 5. Location of proposed plantings. 6. Construction details. 7. Where existing plantings are to be retained 8. Proposed methods of protecting existing plantings during construction. D. Site protection and general planting requirements. 1. Topsoil preservation. Topsoil moved during the course of construction shall be redistributed on all re-graded surfaces so as to provide at least four (4) inches of even cover to all disturbed areas of the development and shall be stabilized by seeding and planting. 2. Removal of debris. All stumps and other tree parts, litter, brush, weeds, excess or scrap building materials or other debris shall be removed from the site within thirty (30) days of notification by the zoning administrator and disposed of in accordance with the law. No tree stumps, or portions of tree trunks or limbs shall be buried anywhere in the development. All dead or dying trees, standing or fallen, shall be removed from the site within thirty (30) days of notification by the zoning administrator. If trees or limbs are reduced to chips, they may be used as mulch in landscaped areas, subject to approval by the administrator. 3. Protection of existing plantings. Maximum effort should be made to save fine specimens. No material or temporary soil deposits shall be placed within four (4) feet of shrubs or ten (10) feet of trees designated on the landscape plan to be retained. Protective barriers or tree wells shall be installed around each plant and/or group of plants that are to remain on the site. Barriers shall not be supported by the plants they are protecting, but shall be self supporting. They shall be a minimum of four (4) feet high and constructed of a durable material that will last until construction is completed. Snow fences and silt fences are examples of acceptable barriers. 4. Slope plantings. Landscaping of all cuts and fills and/or terraces shall be sufficient to prevent erosion, and all roadway slopes steeper than one foot vertically to three (3) feet horizontally shall be planted with ground cover appropriate for the purpose and the soil conditions, water availability and environment. 5. Additional landscaping. In high density residential developments, besides the screening and street trees required, additional plantings or landscaping elements may be required where necessary for privacy, or other reasons in accordance with the landscape plan approved by the planning commission and taking into consideration cost restraints. In nonresidential developments, all areas of the site not occupied by buildings and required improvements shall be landscaped by the planting of grass or other ground cover, shrubs, and trees as part of the landscape plan approved by the planning commission. 6. Planting specifications. Deciduous trees shall have at least a two-inch caliper at planting. Size of evergreens and shrubs shall be allowed to vary depending on setting and type of shrub. Only nursery grown plant materials shall be acceptable, and all trees, shrubs, and ground covers shall be planted according to accepted horticultural standards. Dead and dying plants shall be removed from the site within thirty (30) days of notification by the zoning administrator and shall be replaced by the developer during the following planting season. 7. Plant species. The plant species selected should be hardy for this climactic zone and growing season and appropriate in terms of function and size. E. Shade trees. 1. Location. Shade trees shall be installed in accordance with the approved landscape plan. Trees shall be either massed or spaced evenly as design and/or topographic considerations may determine. When trees are planted at predetermined intervals along streets, spacing shall depend on tree size, as follows. When the spacing interval exceeds forty (40) feet, small ornamental trees can be placed between the larger trees. If a street canopy effect is desired, trees may be planted closer together following the recommendations of a landscape professional. The trees shall be planted so as not to interfere with utilities, roadways, sidewalks, sight easements, or street lights. Tree location, landscaping design, and spacing plan shall be approved by the planning commission as part of the landscape plan. 2. Tree type. Tree type may vary depending on overall effect desired, but as a general rule, all trees on a street shall be the same kind except to achieve special effects. Selection of tree type shall be approved by the planning commission. 3. Planting specifications. All trees shall have a caliper of two (2) inches and be nursery grown, of substantially uniform size and shape, and have straight trunks. Trees shall be properly planted and staked and provision made by the applicant for regular watering and maintenance until they are established. Dead and dying trees shall be removed from the site within thirty (30) days of notification by the zoning administrator and shall be replaced by the applicant during the next planting season. F. Buffering. 1. Function and materials. Buffering shall provide a year round visual screen in order to minimize adverse impacts. It may consist of fencing, evergreens, berms, rocks, boulders, mounds, or combinations thereof to achieve the same objectives. 2. When required. Every development shall provide sufficient buffering when topographical or other barriers do not provide reasonable screening and when the planning commission determines that there is a need (1) to shield neighboring properties from any adverse external effects of a development; or (2) to shield the development from negative impacts of adjacent uses such as streets or railroads. In high density residential developments, when building design and siting do not provide privacy, the planning commission may require landscaping, fences, or walls to screen dwelling units for privacy. Buffers shall be measured from side and rear property lines, excluding driveways. 3. Amount required. a. Where a professional or business zoned development abuts a residential zoning district, a natural buffer strip twenty-five (25) feet in width shall be required. Where site considerations do not allow a natural buffer of twenty-five (25) feet width, a solid privacy fence or wall may be substituted for all or a portion of that buffer, as determined by the zoning administrator. b. Where a commercial zoned development abuts a residential zoning district, a natural buffer strip of fifty (50) feet in width shall be required. Where site considerations do not allow a natural buffer of fifty (50) feet width, a solid privacy fence or wall and twenty-five (25) feet natural buffer strip may substitute. c. Where an industrial zoned development abuts a residential zoning district, a natural buffer strip of one hundred (100) feet in width shall be required. Where site considerations do not allow a natural buffer of one hundred (100) feet width, a solid privacy fence or wall and fifty (50) feet natural buffer strip may substitute. d. Parking lots, garbage collection and utility areas, and loading and unloading areas shall be screened around their perimeters by a buffer strip a minimum of five (5) feet width or privacy fence or wall, as determined by the zoning administrator. e. Where residential subdivisions abut higher order streets (collectors or arterials), adjacent lots shall front on lower order streets, and a landscaped buffer area shall be provided along the property line abutting the road. The buffer strip shall be a minimum of twenty-five (25) feet wide or wider where necessary for the health and safety of the residents. It shall include both trees and shrubs. 4. Design. Arrangement of plantings in buffers shall provide maximum protection to adjacent properties and avoid damage to existing plant material. Possible arrangements include planting in parallel, serpentine, and broken rows. If planted berms are used, the minimum top width shall be four (4) feet, and the maximum side slope shall be 2:1. 5. Planting specifications. Plant materials should be sufficiently large and planted in such a fashion that a year-round screen at least eight (8) feet in height shall be produced within one growing season. All plantings shall be installed according to accepted horticultural standards. 6. Maintenance. Plantings shall be watered regularly and in a manner appropriate for the specific plant species through the first growing season, and dead and dying plants shall be removed within thirty (30) days of notification by the zoning administrator and shall be replaced by the property owner during the next planting season. No buildings, structures, storage of materials, or parking shall be permitted within the buffer area; buffer areas shall be maintained and kept free of all debris, rubbish, weeds, and tall grass. G. Parking lot standards. 1. Amount. In parking lots the interior parking area shall be landscaped with plantings of one tree for each ten (10) parking spaces. Parking lot street frontage screening and perimeter screening shall be a minimum of five (5) feet wide. Planting required within the parking is exclusive of other planting requirements, such as shade trees planted along the street. 2. Location. The landscaping should be located in protected areas, such as along walkways, in center islands, at the end of bays, or between parking stalls. All landscaping in parking areas and on street frontage shall be placed so that it will not obstruct sight distance. 3. Plant type. A mixture of hardy flowering and/or decorative evergreen and deciduous trees may be planted. The evergreens should be used along the perimeter of the lot for screening, and the deciduous trees for shade within the lot. The area between the trees shall be mulched, planted with shrubs or ground cover, or covered with paving materials. Any area that will extend under the overhang of vehicles shall be mulched or covered with paving material. K. General requirements and minimum standards. 1. All required landscaping shall be installed prior to the issuance of a permanent certificate of occupancy. 2. There shall be a minimum street frontage planting strip of five (5) feet in width across the entire lot frontage. This may be a combination of scrubs, trees, grass, and varied landscaping elements. There shall be a minimum of one medium sized shade tree required per each forty (40) feet of lot frontage. All shade trees shall be a minimum of two-inch caliper at time of planting. 3. Existing trees preserved on the site may be used to satisfy the requirements for landscaping. Any tree used to meet the requirements of this ordinance must be at least three (3) inch caliper, in healthy condition, and be protected from construction activity. 4. The owner of the property upon which the required landscaping or buffering is installed shall be responsible for perpetual maintenance and replacement. If any required tree, shrub, or other landscaping element shall die or be removed after issuance of the certificate of occupancy, the developer, his or her successors or assigns, shall replace each by the end of the next planting season with trees or shrubs of like character. 5. Species of trees shall not be planted if the roots cause damage to public works, the branches are subject to high incidence of breakage, and the fruit is considered a nuisance or high maintenance as determined by the director of public works. 6. Landscaping shall not obstruct the view of motorists using any street, private driveway, parking isles, or the approach to any street intersection so as to constitute a traffic hazard or a condition dangerous to the public safety. Whenever the enforcement of the provisions of this ordinance may be deemed a traffic hazard, the zoning administrator may waive any or all requirements. L. Suggested trees and shrubs. 1.

Chapter 33.02 SITE REGULATIONS ARTICLE III. SITE PLAN REGULATIONS AND STANDARDS Sec. 33.02-51. Landscaping and green area required. (a) The area to be developed shall be clearly delineated on the site plan(s). Within such area and subject to the provisions of this section, a minimum percent of the site shall be designated as landscaping and green area as follows: (1) Ten (10) percent of the area to be developed shall be so designated for a site containing less than forty-five thousand (45,000) square feet. (2) Fifteen (15) percent of the area to be developed shall be so designated for a site containing forty-five thousand (45,000) square feet and no more than ninety thousand (90,000) square feet, subject to modifications that are authorized by this section. (3) Twenty (20) percent of the area to be developed shall be so designated for a site containing more than ninety thousand (90,000) square feet, subject to modifications that are authorized by this section. (4) Landscaping and green area requirements of this section do not apply when improvements are made on existing impervious areas. Demolition of a majority (50.1% or more) of the primary structure on the site shall require the entirety of the site to come into compliance with the chapter. (b) The following requirements shall be applicable to the landscaping and green area within the developed area: (1) Existing trees. All landscaping and green areas must be identified on the plan. Within those landscaping and green areas, healthy existing trees of a minimum six (6) inch DBH (diameter at breast height), measured at least four and one-half (4.5) feet above grade, for single-stemmed, deciduous trees, and of a minimum eight (8) feet in height for multi-stemmed or evergreen trees, shall be retained, preserved and protected during construction in accordance with the following: a. Preserved trees shall be identified by size and variety, clearly marked in the field, and shown on the landscaping, erosion and sedimentation, demolition, and grading plans. B. In naturally vegetated areas of one thousand (1,000) square feet or more, groups of trees rather than single trees may be identified on the plan. Existing tree canopy limits shall be clearly shown on all plans. Within the tree canopy limits shown on the plan(s), an accounting shall be provided stating the minimum quantities, sizes and varieties of trees to remain in each group. C. Existing healthy, single-stemmed deciduous trees meeting a minimum of two (2) inch caliper measured six (6) inches above the ground and no less than eight (8) feet in height, and multi-stemmed or evergreen trees meeting a minimum of eight (8) feet in height which are preserved and protected on-site, may be counted toward meeting the requirements identified below in subsection (2). D. When the loss creates a quantity deficit or void in spacing for the minimum requirements of this section, any preserved tree(s) on-site shall be replaced if such tree(s) should die, or at such time that fifty (50) percent of the tree crown is severely trimmed, damaged, diseased or dead. If trees to be replaced are four (4) inch caliper or less for single stemmed species, or twelve (12) feet in height for evergreen or multi-stemmed species, they shall be replaced with trees the same size as those removed. If trees to be replaced are greater than four (4) inch caliper for single stemmed species, or twelve (12) feet in height for evergreen or multi-stemmed species, then replacement trees shall be a minimum of four (4) inch caliper for single stemmed species, or twelve (12) feet in height for evergreen or multi-stemmed species. E. Individual trees and groups of trees that are preserved shall be enclosed by a temporary fence or barrier to be located and maintained five (5) feet outside the dripline of the tree(s) during construction. Such a fence or barrier shall be installed prior to clearing, construction or issuance of a land disturbing permit (section 33.02-8, Site Regulations, and chapter 35, Soil Removal and Other Land Disturbing Activities). The tree protection fencing shall be a minimum of forty (40) inches in height and sufficient to prevent intrusion into the protected area during construction In no case shall materials, vehicles or equipment be stored or stockpiled within the enclosure. F. The property owner, the owner's agent or the developer, as applicable, shall be responsible for notifying all construction personnel of the presence and purpose of clearing limits and protective fences or barriers and for ensuring that the restrictions associated with the same are observed. G. Where grade changes in excess of six (6) inches from the existing natural grade level are necessary, permanent protective structures, such as tree wells or walls, shall be properly installed by the property owner, the owner's agent or the developer, as applicable. H. The director may allow trees to be removed in the case of hardship in developing the site, when the tree becomes irreversibly diseased or damaged by natural causes, or when prohibited by FAA regulations. Such tree removal(s) shall be based on the following: 1. The number of trees to be removed are replaced with at least an equal number of trees meeting the size and species provisions of this section. Replacement trees shall be located in such a manner so as to more effectively landscape the entire site, taking into consideration the objectives of dispersal, screening, pedestrian and vehicular movement on-site, and the size and location of proposed buildings. 2. Existing trees that fall within proposed parking islands of four hundred (400) square feet or less shall not be required to be preserved and protected. However, replacement trees shall be required, meeting the provisions of section 33.02-52, and provided within all interior parking islands as well as in the landscaping and green areas at the ends of parking rows. 3. For sites located on property of the Newport News Williamsburg International Airport, the director may waive the preservation of existing trees that may affect aviation safety.

(10) A landscape strip shall be located along street frontage. Landscaping in this strip shall include at least one (1) tree, either existing or installed, in every thirty (30) feet of street frontage, exclusive of driveway entrances. The remainder of the required landscaped strip shall consist of shrubs, grass, ground cover or other landscape treatment approved by the director in conjunction with the review of a site plan. The director may reduce the width of the landscaped strip by up to fifty (50) percent along minor streets when the total site is less than twenty thousand (20,000) square feet. A. For public streets, the landscaped strip shall be placed along the right-of-way and located between the adjacent right-of-way line and either the front building setback line or parking lot, whichever is closer to the adjacent right-of-way. The width of this strip shall be a minimum of ten (10) feet or ten (10) percent of the existing right-of-way width or the proposed right-of-way width, whichever is greater, included in the appropriate transportation plan.

The plan relates to modifying an existing building whose physical characteristics preclude full compliance; or, b. Pre-existing physical characteristics of the site preclude full compliance (e.g., building takes up most of the property or limited setback distance is available). (3) The minimum percentage of the site area that shall be designated as landscaping and green area in subsections (a)(2) and (a)(3) above may be reduced by the director to no less than ten (10) percent for sites requiring a minimum of fifteen (15) percent green area and no less than twelve (12) percent for sites requiring a minimum of twenty (20) percent green area. Each of the following may account for up to one-third (1/3) of the allowable reduction: a. Every additional tree planted over the minimum required may reduce the required landscaping and green area by three hundred (300) square feet. B. Every additional shrub planted over the minimum required may reduce the required landscaping and green area by one hundred thirty-five (135) square feet. C. Where parking is screened by an earthen berm or other visual barrier planted with approved ground cover and shrubs, and the top of berm is at least two and one-half (2.5) feet above ground and within a minimum slope of 2.5:1, each linear foot of such berm may be used to reduce the required landscaping and green area by fifty (50) square feet. Berms proffered can qualify for landscaping and green area reduction under this section. (4) If a master landscape plan is approved by the director, all individual sites participating in such plan shall be able to reduce the minimum required landscaping and green area percentage to ten (10) percent where the minimum following criteria are included: a. A landscape strip shall be established along all streets a minimum width of ten (10) feet from the property line or edge of a private street right-of-way. B. Trees shall be planted at a minimum of thirty (30) feet on center in this strip exclusive of driveway entrances. C.

(b) Whenever a subdivision is classified as a major subdivision, the subdivider shall provide street improvements as set forth in Table 400-1. (c) Curb and gutter, planted strips, street trees, and sidewalks shall be provided on both sides of a new street. Where lots are being established on only one (1) side of a new street, and where topographic conditions would preclude future establishment of lots on the undeveloped side of the street, sidewalks shall not be required on the side of the street where no lots are being created. Where a subdivision takes place only on one (1) side of an existing street, such improvements shall be required only on the side on which the subdivision takes place. ? (f) Street trees shall be planted along the entire length of the street being created or improved, exclusive of areas required to remain clear for the purposes of sight distance. (1) The minimum number of street trees required shall be calculated by dividing the block length, minus twenty (20) feet of sight distance required at each corner of the block, by forty (40). Any fractional remainder may be rounded down to a whole number. The required number of trees may be reduced by the number of street lights located more than twenty (20) feet from an intersection. (2) Street trees shall be provided in the planted strip between the sidewalk and curb or within tree grates located in an extended-width sidewalk as permitted in Table 400-1. Street trees shall be located with centers a minimum of three (3) feet from the back of the curb in a planted strip or in tree grates along an extended-width sidewalk. A minimum of five (5) feet of clearance shall be maintained between street trees and underground utilities. (3) Street trees shall be planted in accordance with the Standardized Landscape Specifications for the Commonwealth of Virginia, 2000, jointly adopted by the Virginia Nurserymen's Association, the Virginia Society of Landscape Designers, and the Virginia Chapter of the American Society of Landscape Architects. (4) All trees required by this section shall be selected from the approved tree list in Table 400-3 and shall meet the specified minimum caliper or height at the time of planting. The subdivision agent may approve the use of trees not set forth in Table 400-3 to meet the minimum street tree requirements of this section, provided the subdivision agent determines the proposed alternative species are consistent with the intent of this section. The resource for such determination shall be based on the published reference text, Manual of Woody Landscape Plants, fifth edition, 1998, by Michael A. (g) The subdivision agent, in consultation with the city engineer and city traffic engineer, will review proposed street lighting to determine that the overall layout and design of street lights are adequate for the streets and related pedestrian ways as to the height of poles, shielding of light sources, and that placement is coordinated with the location of street trees and other public improvements. A certificate of appropriateness from the architectural review board shall be obtained for street lights to be installed in either the Historic Downtown Overlay District (H-1) or the Historic Neighborhood Overlay District (H-2). ?
