ARTICLE VIII. IMPROVEMENTS REQUIRED FOR DEVELOPMENTS
DIVISION 2. LANDSCAPING AND SCREENING
Sec. 34-869. Tree cover requirements.
(a) The provisions of the city's tree canopy ordinance adopted June 25, 1990, are hereby continued in effect and incorporated in this zoning ordinance, as follows:
(1) All developments, public or private, requiring submission and approval of a site plan shall include provisions for the preservation and planting of trees on the site to the extent that, at ten (10) years from planting, minimum tree canopies or covers will be provided as follows:
Zoning Districts: Percentage of Site Cover
- R-3, B-1, B-2, B-3, IC: 10%
- R-2: 15%
- R-1, R-1A: 20%
The area to be occupied by the building footprint(s) and driveway access area(s) proposed for a development site shall be subtracted from the gross site area before calculating required tree coverage only when the site is located within that portion of the city described in section 34-971 (parking exempt area). This exclusion from gross site area calculations shall be allowed whether or not the proposed development will add more than ten (10) percent floor area to an existing building or is found to be new construction in the context of the off-street parking requirements.
(2) Existing trees infested with disease or insects or structurally damaged to the extent that they pose a hazard to persons or property, or to the health of other trees on site, shall not be included to meet the tree cover requirements.
(3) The requirements of this section may be waived, in whole or in part, by the director of neighborhood development services or the planning commission in the following circumstances: to allow for the reasonable development of areas devoid of woody materials, dedicated school sites, playing fields and other non-wooded recreation areas, and other facilities and uses of a similar nature; to allow for the preservation of wetlands; or when strict application of the requirements would result in unnecessary or unreasonable hardship to the developer.
(b) Within all zoning districts other than those specifically referenced within paragraph (a), above, tree cover shall be provided to the extent that, at twenty (20) years, minimum tree canopies or covers will be provided (relative to the gross area of the development site) as follows:
(1) Ten (10) percent canopy for a development site zoned for business, commercial or industrial use;
(2) Ten (10) percent for a development zoned for residential use at a density of twenty (20) or more units per acre;
(3) Fifteen (15) percent for a development zoned for residential use at a density of more than ten (10) but less than twenty (20) units per acre; and
(4) Twenty (20) percent for a development zoned for residential use at a density of ten (10) units per acre or less.
(5) The area to be occupied by the building footprint(s) and driveway access area(s) proposed for a development site shall be subtracted from the gross site area before calculating required tree coverage only when the site is located within that portion of the city described in section 34-971 (parking exempt area), or within one (1) of the following mixed-use zoning districts: Downtown (D); West Main North (WM-N), and West Main South (WM-S). The following areas may be deducted, at the option of the developer, from the gross area of the site: required recreation areas; required open space areas; land dedicated to public use; playing fields and recreation areas attendant to schools, day care, and similar uses; areas required for the preservation of wetlands, floodplain or other areas required to be maintained in a natural state by this chapter or other applicable law; and other areas approved by the director as part of a variation or waiver of the landscape plan requirements.
(6) For any mixed-use development: whether such development falls within the category of a site zoned for residential, commercial or industrial use shall be determined by the principal (predominant) use.
(c) Where existing trees are preserved on the development site, a bonus shall be granted as follows ("tree canopy bonus"): in calculating the coverage provided by trees shown on the approved landscape plan, an existing tree included on the developer's conservation checklist shall be deemed to cover an area equal to one and one-half (1.5) times the diameter of the tree's existing dripline. In order to qualify for this bonus, an existing tree must have a caliper of at least eight (8) inches.
(d) Streetscape trees required by section 34-870 may be counted toward tree cover requirements.
(e) Within the city's list of approved plantings, the director shall designate any tree species that cannot be planted to meet minimum tree canopy requirements due to tendencies of such species to: (i) negatively impact native plant communities; (ii) cause damage to nearby structures and infrastructure; or (iii) which possess inherent physiological traits that cause such trees to structurally fail.

? 19-600. Landscaping and buffering.
A. In General. This section of the zoning ordinance of the city of Chesapeake shall be known and may be cited and referred to as the Chesapeake Landscape Ordinance. The Chesapeake Landscape Specifications Manual, including definitions, is hereby incorporated into and made a part of this ordinance.
B. Intent. The intent of this ordinance is to provide minimum standards for the preservation, protection and enhancement of the ecologic and aesthetic environments of the City of Chesapeake. The urban forest which includes all landscaped areas within the city, serves to prevent soil erosion; reduce the hazards of flooding; absorb carbon dioxide and supply oxygen; reduce the effects of noise, glare, dust, and other objectionable activities generated by some land uses; provide shade and reduce adverse effects of winds; safeguard and enhance property values; buffer and screen adjacent properties; and promote the pleasant appearance and character of neighborhoods.
(Ord. No. 97-O-141, 11-18-97)
? 19-601. All sites.
A. Landscaping plan requirements.
1. A preliminary landscaping plan, showing the location and dimensions of green space, buffer yards, and existing and known proposed public and private easements, shall be required as part of any preliminary site plan for all multifamily and nonresidential developments and for all residential major subdivisions where rear or secondary front yards abut an existing or proposed right-of-way 80 feet or more in width.
2. A final landscaping plan, prepared by a landscape designer, shall be submitted in the following circumstances: (1) as part of the final site plan for any multifamily or nonresidential development; (2) as part of the building permit application for any single-family or duplex residential construction on a lot, and (3) as part of any final subdivision plan for a residential major subdivision where rear or secondary front yards abut an existing or proposed right-of-way 80 feet or more in width.
3. Such landscaping plans shall contain the landscaping and/or plant replacement specifications required under this ordinance, including the Chesapeake Landscape Specifications Manual, which is hereby incorporated into and made a part of this ordinance by reference.
B. Site analysis. A site analysis, including all tree preservation areas, is required as part of the submittal of each preliminary and final subdivision plat, site plan, or erosion and sediment control plan submitted to the city. Such site analysis shall, by plan and narrative, include all those elements required by the Chesapeake Landscape Specifications Manual. The site analysis may, upon approval of the director of development and permits, or designee, based on-site conditions, be presented in a narrative format only.
C. Townhouse communities. In townhome communities where adequate space does not exist for the placement of trees otherwise required under this ordinance, the city may approve the placement of trees in open spaces, common areas or end lots where adequate and appropriate space for mature growth exist. If such a plan is approved, it shall be the developer's responsibility to set forth a schedule for the installation of these plantings that meets the approval of the city. Further, the developer shall be responsible to call for city inspection and approval of said landscaping upon completion.
D. Parking areas.
1. Green space meeting the definition contained in the Chesapeake Landscape Specifications Manual shall be provided within the interior of parking areas at a ratio of 30 square feet of greenspace per each off-parking space provided; off-street parking space as defined in section 19-408 of this ordinance. Only those areas directly adjacent to and directly associated with the rows of parking will count towards required green space.
2. The equivalent of 400 square feet of large tree canopy coverage (appendix B of the Chesapeake Landscape Specifications Manual) shall be planted for each 150 square feet of interior green space provided.
3. Where feasible, as determined by the director of development and permits, or designee, utilities shall be located outside of required green space.
4. Green space containing less than 150 square feet in contiguous area will not count toward interior green space required for parking. Individual green areas 150 square feet or more in contiguous area shall not substitute for more than 1,000 square feet of interior green space required for parking.
5. A maximum of 30% of the required interior green space may be combined with required buffer yards when natural vegetation is being retained in any such buffer yard. This combination of required areas shall only be permitted in the vicinity of, and in conjunction with, tree preservation, as approved by the director of development and permits, or designee. When tree preservation is approved, up to 1,500 square feet of contiguous interior green space may count toward interior green space requirements.
6. Green space no smaller than 9 x 18 feet in size, and containing at least one large tree, shall be required at both ends of each row of parking spaces containing 7 or more spaces. All parking lot trees shall be large trees, as listed in the Chesapeake Landscape Specifications Manual, unless sotherwise approved by the director of development and permits, or designee, due to extenuating circumstances.
E. Buffer yard requirements.
1. Where the zoning classification for a site to be developed under this section is more intense than the classification of a property bordering such site, the landscaping plan for the more intensely zoned site shall include provisions for a buffer yard and/or structure required along the length of the property line that separates the site from the property having a less intense zoning classification, as provided for in section 19-610 below.
2. A vegetated buffer as described in and required by section 19-610 shall be installed on those sites bordering public or private streets, including alleys, service drives and rights-of-way, unless waived or modified by the director of development and permits, or designee, pursuant to section 19-606 of this ordinance. All required landscaping shall be set back from the street and ingress/egress points an adequate distance to provide clear visibility, in accordance with section 19-204 of this ordinance. Tree locations and spacing may be adjusted to provide reasonable visibility of signage and to ensure safe ingress/egress.
3. Street frontage hedges shall be restricted to a mature height of 4 feet except where they are required to screen service entrances and outside storage areas, where they shall be maintained at a height of 6 feet.
4. A minimum of 7 feet width, or 50 % of the required width, whichever is greater, of any required buffer yard must be located outside of all public or private easements. Where feasible, required trees must be located outside of all public easements or private utility easements. The director of development and permits, or designee, shall determine on a case-by-case basis whether the location of trees outside of a particular utility easement is feasible, giving due consideration to such factors as topography, size of the lot and site design. No trees shall be planted in an easement where prohibited by the deed or agreement by which the easement was created. Required shrubs may be planted within a utility easement, provided that shrubs are not prohibited by the deed or agreement which created the easement. If no deed or agreement exists, no plant materials shall be placed in the easement area without the express permission of all persons having rights or interest in the easement.
5. Buffers required adjacent to public or private rights-of-way with an existing or proposed width of 80 feet or more are to be provided by the landowner or developer and depicted on the final subdivision plat recorded in the clerk's office of the circuit court of the City of Chesapeake. The plat shall contain a note stating that no structure shall be located in the buffer and that all plant materials therein are to be maintained by the owner of the property.
6. Screening for communication towers shall be in conformance with section 13-606 of this ordinance.
7. A buffer yard D as described in Section 19-610 of this ordinance, with a three-foot berm, shall be required where the rear of any commercial or industrial building faces a public or private right-of-way having an existing or proposed width of 80 feet or more.
8. For additional buffer yard and screening requirements, see Section 14-200, Fences, walls and hedges; Section 14-500, Trash receptacles; and Section 14-700, Signs.

Sec. 19-602. The preservation and canopy requirements.
The landscape plan for every site shall contain the tree preservation and canopy requirements set out below.
A. Tree preservation areas. Tree preservation areas which are marked on the plan shall be clearly delineated on the site. These areas are to be protected from traffic, equipment, excavation, stockpiles and staged materials. Areas set forth as tree preservation areas must remain marked and protected during construction in order to be included in the calculation of the required canopy.
B. Tree canopy requirement?Nonresidential development. Each plan for nonresidential development shall provide a landscaping plan that, at tree maturity, provides a minimum canopy of ten percent (10%) of the calculation area.
C. Tree canopy requirement?Residential development. Each residential plan shall provide a landscaping plan that, at tree maturity, provides minimum tree canopy as set out below.
1. Tree canopy totaling fifteen percent (15%) of the calculation area for a residential site zoned for multifamily or townhouse use.
2. The following tree canopy requirements apply to lots zoned single-family residential and lots zoned agricultural lawfully used for residential purposes:
a. For lots smaller than one-half acre in size, twenty (20) percent of the calculation area as approved by the director of development and permits, or designee.
b. For lots one-half (?) acre and larger, twenty (20) percent of the calculation area with a maximum requirement of eighteen (18) large trees or thirty-six (36) small trees or a combination as approved by the director of development and permits, or designee. Required trees shall be six (6) to eight (8) feet in height at the time of planting.
D. Requirements for preservation and replacement. The canopy requirements set out above shall be met by preservation or replacement methods as indicated in the Chesapeake Landscape Specification Manual. Where final site conditions will make the successful preservation of existing plants unlikely, the City of Chesapeake may direct the owner or developer to provide new, appropriate species and locations to ensure canopy coverage as set forth by the ordinance.
E. Incentives for preservation of trees. A credit toward canopy requirements will be given for the preservation of an outstanding tree, as defined in the Chesapeake Landscape Specifications Manual, or for the preservation of a cluster of trees, approved by the director of development and permits, or designee, pursuant to the following:
1. The credit provided per outstanding tree will be 2.0 multiplied by the area defined by the boundaries of the existing drip line of the tree.
2. The credit provided for a cluster of trees will be 1.25 multiplied by the area defined by the boundaries of the existing drip line of the cluster.

(2) Replacement tree canopy coverage shall be as calculated by the most recent standards for tree canopy coverage by the Virginia Nursery and Landscape Association. Vegetation that is not included in this list may be substituted for vegetation of similar growth rate, type and form.
(e) Existing vegetation that shall be credited towards the required tree canopy coverage includes:
(1) Existing or relocated trees and/or shrubs that have been preserved in accordance with a landscape conservation plan, pursuant to article IV, division 16 of this chapter, pertaining to Chesapeake Bay preservation area overlay district.
(2) Canopy coverage from existing trees and/or shrubs shall be multiplied by 1.25 to determine the total tree canopy from preserved trees and shrubs. This is to encourage the preservation of existing vegetation and to recognize the additional environmental benefits that mature trees provide.
(f) Existing vegetation that shall not be credited towards the required tree canopy coverage include:
(1) Trees with a rating of fair to poor and with a life expectancy less than ten years, as calculated by the city arborist using the most recent edition of the Guide for Plant Appraisal, published by the International Society of Arboriculture.
(2) Undesirable and/or invasive vegetation, as published by the Virginia Department of Conservation and Recreation (DCR) and the Virginia Native Plant Society (VNPS).
(g) Replacement vegetation is required on lots that do not meet the minimum tree canopy coverage requirements either through the preservation of existing vegetation or due to the absence of tree canopy coverage present at the time of development or redevelopment.
(1) Replacement vegetation should be chosen from the Recommended List of Trees and Shrubs to Plant in the City of Falls Church.
(2) Substitute vegetation may be considered, provided it does not negatively impact native plant communities, cause damage to nearby structures and infrastructure, or possess inherent physiological traits that cause such trees to structurally fail.
(3) Size, planting and installation specifications of the required replacement vegetation shall be pursuant to this section.
(h) In addition to the quantity of the replacement vegetation, its quality shall be encouraged through providing tree canopy coverage credit. Credit shall be given for the following types of vegetation that are selected and planted on the lot so that it improves the overall health and condition of the urban tree canopy and provides for additional environmental benefits.
(1) A best management practice (BMP) credit of 25 percent of the tree canopy of the individual tree shall be given for those trees that are used in rain gardens, bio-retention areas or other vegetative best management practices.
(2) An energy conservation credit of 25 percent of the tree canopy of the individual tree shall be given for those types of trees that are an approved species for energy conservation. Trees shall be located 20 to 35 feet from the edge of a building and shade its western, southwestern or northern exposure from 2:30 p.m. to 7:30 p.m. from May through September.
(3) A species diversity credit of an additional ten percent shall be given for the use of not more than 20 percent of the trees to be of the same species.
(4) A utility line compatibility credit of the average of the listed shade trees shall be given for trees that are an approved species that do not conflict with overhead utility lines. This credit applies when site constraints do not allow for the planting of shade trees elsewhere on the lot.
(i) Installation and bonding requirements of replacement vegetation shall be regulated pursuant to article V, division 7 of this chapter, pertaining to site plans.
(j) Where areas to be preserved (as designated on an approved landscape conservation plan) are encroached upon, the city arborist may require the replacement of any vegetation damaged or destroyed. The size, species and quantity of these replacements shall be determined by the city arborist based on the value of the vegetation removed as calculated by the latest formula published by the International Society of Arboriculture.
(k) Modifications to the tree canopy coverage requirement in this section may be permitted when in the professional opinion of the city arborist, a lot's unique physical constraints will not allow for the planting of the replacement vegetation. Only in these cases, the city arborist may allow a cash contribution to the tree canopy coverage fund or off-site mitigation fund whereby a portion of a lot's tree canopy coverage requirements may be met from off-site mitigation planting or replanting at locations at the direction of the city arborist.
(l) The tree canopy coverage fund or off-site mitigation fund shall be established for the deposit of cash contributions and mitigation fees, when necessary, and administered by the city arborist. This fund shall be utilized to plant trees on public and/or private properties within the city boundaries.
(1) Cash contribution shall be based upon the replacement cost of the vegetation. The replacement cost shall be the sum total of all costs to purchase, transport, plant and guarantee the tree for one year from the date of planting.
(2) Requests for tree plantings on private property shall be prioritized based on the lot's location in the sub watershed, existing tree canopy coverage and other site conditions that would improve the urban tree canopy. The commitment of the homeowner to provide longterm care for the planting shall be required.
(3) Tree plantings shall be contracted out yearly and documentation provided to the tree commission and/or other interested parties as to the fund's administration, and the locations and types of trees planted.

ARTICLE III. TREE PLANTING AND REPLACEMENT
Sec. 36-52. - Standards for planting and replacement of trees.
The following standards shall apply to the planting and replacement of trees:
(1) Any preliminary or final subdivision plat submitted in accordance with the subdivision ordinance (chapter 33 of the city Code), which creates a lot any site development plan submitted in accordance with the zoning ordinance (chapter 40 of the city Code), and any application for a building permit for a principal residential structure shall include a landscape plan. The landscape plan must be drawn to the same scale as the plat or site development plan and shall clearly indicate trees to be retained or planted to meet the requirements of this article. Trees to be retained on the site shall be clearly indicated by common and botanical names; their actual location on the site; and the extent of the site covered by the canopy of each tree. Stands of five or more trees may be grouped together and shall indicate the overall area to be encompassed by their canopies. Critical protection zones for all trees to be retained, as well as a description of any protective devices proposed to comply with subsection (10) of this section, shall be indicated. Trees to be planted on the site shall be clearly indicated by botanical and common names, their proposed locations on the site; and caliper and height. The plan shall include a note indicating that trees shall be planted in conformance with subsections (9)a and (9)b of this section. When a landscape plan for a site has already been approved as part of a subdivision or site development plan for a larger development, no new landscape plan shall be required, provided that the development of the site shall comply with all other provisions of this article.
(2)
a. The landscape plan shall provide for the planting or replacement of trees on the site to the extent that, after 20 years, minimum tree canopy cover percentages will be provided as specified in the Table 36.1, which table has been printed at the end of this article.
b. Canopy cover calculations shall be made based upon data provided in "Trees and Shrubs for Virginia Landscapes," Volume 1, 1989, by Bonnie Lee Appleton and Terri Chappell for the Virginia Nurserymen's Association; "Handbook of Landscape Tree Cultivars," 1989, by Willet N. Waddell; and "Landscape Plants in Design," 1983, by E. C. Martin, Jr. If a range of distance is provided for the width of a tree, the average of the range shall be used. In cases of conflict among the references, the larger width specification shall be used. The determined width shall then be divided by two to determine the radius of the tree canopy. This radius shall be multiplied by two-thirds to obtain the 20-year radius. The area of the canopy cover of the tree shall be calculated using the 20-year radius. If no data is provided in the references for a tree proposed to be used, canopy cover of the proposed tree and the reference source used to calculate that canopy cover shall be indicated on the landscape plan. To encourage the planting of a variety of tree species, the following credit will be given for each tree:
Calculated 20-Year Tree Canopy (Square Feet): Allowed Credit (Sqaure Feet)
- 0-300: 300
- 300-1,000: 1,000
- 1,000 +: 2,000
(3) The area of a site to be used in calculating canopy cover shall be the area of the zone lot as defined in chapter 40.
(4)
a. Trees shall be selected from those listed in the "Landscape Planting and Protection Manual, Portsmouth, Virginia," which may be amended as necessary by the city manager or his designee. Substitutions using trees not on the list may be made with the approval of the director or the director's designee. No tree from the list of nonacceptable trees may be used.
b. Small trees with single stems must have a caliper of 1? inches at the time of planting. Multistem trees must be a minimum of five feet in height at time of planting. Medium trees must have a minimum caliper of 1? inches and large trees must have a minimum caliper of two inches at time of planting. All trees must be planted in accordance with the planting specifications of subsection (9) of this section.
(5) Trees existing on the site may be used to satisfy the canopy coverage requirements of subsection (2) of this section. The landscape plan must identify such trees. Trees must be physically and structurally in good condition. All such trees on the site during construction must be protected in accordance with the provisions of subsection (10) of this section. Stands of five or more trees shall be credited canopy area equal to that covered at the time of application for approval of the landscape plan.
(6) Existing or proposed street trees planted or to be planted along the street in the public right-of-way may be used to satisfy the canopy coverage requirements. All trees must be approved by the director or the director's designee as required in subsection (7) of this section.
(7) No landscape plan shall be approved unless the director or the director's designee makes the following certifications:
a. All existing trees to be retained in compliance with the requirements of this article are physically and structurally sound;
b. Where street trees are proposed, the landscape plan provides for acceptable spacing, lawn area and species selection in relation to streets, sidewalks, utilities, traffic sight lines and parking areas.
(8) No certificate of occupancy shall be issued for any part of the development until the trees required by subsection (1) of this section for that part have been planted and all such trees have been determined to be physically and structurally sound by the director or by the director's designee. In lieu of actual planting, an applicant for a certificate of occupancy may post a bond or other form of security acceptable to the city attorney to ensure the timely completion of the approval tree planting plan.
(9) All trees to be planted shall be installed in conformance with the following criteria:
a. All trees to be planted in accordance with "American Standards for Nursery Stock," published by the American Association of Nurserymen. All trees shall be balled and burlapped or container-grown.
b. All trees shall be installed in accordance with the road and bridge specifications of the Virginia Department of Transportation and "Landscape Planting and Protection Manual, Portsmouth, Virginia."
c. The owner of the property shall be responsible for the continued proper maintenance of all trees located on the property. Where trees are installed in accordance with the provisions of this article, it shall be the responsibility of the lot owner to maintain the trees. The trees must be maintained, alive, for a period of one year. If any of the trees dies during the first year after planting, it must be replaced by the owner.
(10) Trees to be retained on the lot in accordance with the approved landscape plan shall be protected utilizing methods prescribed in "Landscape Planting and Protection Manual, Portsmouth, Virginia."
a. Trees or tree areas that are to be retained shall be marked visibly in the field prior to clearing or construction by use of one of the methods specified in the "Landscape Planting and Protection Manual, Portsmouth, Virginia."
b. Protection devices shall be installed prior to clearing or construction and shall be shown on the submitted landscape plan. Such devices shall be evident and effective and shall be maintained at all times. Failure to maintain such devices shall be cause for the issuance of a stop work order. Construction personnel shall be notified of the purpose and presence of the protection devices.
c. If it becomes necessary subsequent to clearing to remove additional trees which were shown on the approved plan to be retained, such trees may be removed if compliance with the required canopy coverage and all other requirements of this article are maintained and a revised landscape plan is approved.

The planning director may grant a partial exception to the requirements of this article under the circumstances listed in this section:
(1) Such exception shall reduce the required tree canopy by the minimum extent necessary to provide a reasonable buildable area.
(2) Exceptions may be granted under the following conditions:
a. Where the planning director finds that the combined requirements of this article, the zoning ordinance, any ordinances adopted in compliance with the Chesapeake Bay Preservation Act, or the requirements of chapter 39 of the city Code for the protection of tidal wetlands would result in the elimination of a reasonably developable area on the site.
B. Where the proposed use of the property is agriculture, outdoor recreation, or aviation and the planning director finds that full compliance with this article would unreasonably reduce the unwooded area of the site necessary for such use.
C. Where the proposed development is an expansion of an existing development on the same zone lot, the procedure for calculating required tree canopy coverage shall be modified by substituting the term "construction footprint" for the term "zone lot" in section 36-52(3).

When adjustment is necessary, spacing shall not exceed the maximum allowable spacing. No trees shall be placed within ten (10) feet of a streetlight pole nor encroach within the visibility triangle as defined by section 201(f) of the city zoning ordinance. Generally, a minimum of four (4) feet of greenspace on either side of the sidewalk shall be required.
E. Trees on residential lots shall not be used to meet the requirements of street tree planting, except when a lot or group of lots are heavily wooded and the planting of street trees would physically conflict with the canopy of the residential trees. The street tree requirements may be deleted in these areas only. The planning director or his designee shall determine if such a conflict exists.
5. Bonding: Prior to the recordation of any final subdivision plat, the developer shall provide a performance bond with surety, cash escrow, irrevocable letter of credit, any combination thereof, or such other legal arrangement acceptable to the city attorney to cover the costs of such trees and their planting. In the event that the developer fails to plant such trees as required by this ordinance, the city may use the performance bond to cover the cost of purchase and planting of all required street trees. In such event, the developer shall reimburse the city for any excess cost should the cost of purchase and planting of the trees exceed the amount of security provided. A bond shall be required to cover the guarantee period.
C. Exemptions:
1. The requirements of section 1.4.B. of this appendix shall not apply to resubdivisions or to unimproved rights-of-way.
2. The requirements of section 1.4.B. shall not apply to townhouse developments where the street design does not provide adequate greenspace for street trees.
D. Compatibility with best management practices (BMPS). In no case shall a subdivision be approved wherein the design calls for the planting of trees over any underground water retention areas.

ARTICLE IV. SUBDIVISION DESIGN
DIVISION 1. IN GENERAL
Sec. 74-44. Preservation of natural features and amenities.
(a) Generally. Existing natural features that would add value to residential development or to the city as a whole, such as trees, watercourses, historic sites, and similar irreplaceable assets shall be protected wherever practicable in the design of the subdivision.
(b) Site cover requirements.
(1) In subdivision development trees shall be retained to the extent that, at ten years from date of preliminary plat approval, minimum tree canopies or covers (including retained trees and new trees planted under subsection (d) below) will total as far as possible the following site cover percentages:
Zoning Districts Percentage of Site Cover
- Multiple-Dwelling and Industrial District: 10 Percent
- Single-Family Residential Districts: 20 Percent
The area to be occupied by the estimated building footprint(s) and driveway access area(s) proposed for a development site shall be subtracted from the gross site area before calculating required tree coverage.
(2) As used herein, "tree canopy" or "tree cover" shall include all areas of coverage by plant material exceeding five (5) feet in height, and the extent of canopy at maturity shall be derived from the current edition of "Manual of Woody Landscape Plants" by Michael A. Dirr, or other comparable sources.
(3) The applicant shall consult with the city horticulturist as to trees planted to satisfy canopy requirements stated herein.
(4) To curtail the spread of disease or insect infestation in a plant species, when more than five trees are required to be planted on a site, no more than 50 percent of those trees shall be of one type. When more than 20 trees are required on a site, no more than 25 percent of the required trees shall be of a single species.
(c) Existing trees.
(1) The applicant shall provide a tree protection plan to be approved by the city horticulturist and shall protect existing trees, where possible, in the design and development of a subdivision and replace those trees necessarily removed during such development.
(2) All trees that are to be retained shall be marked and protected during construction, with tree wells provided where necessary to protect the tree from changes in grade.
(3) Existing trees infested with disease or insects or structurally damaged to the extent that they pose a hazard to persons or property, or to the health of other trees on site, shall not be included to meet the tree cover requirements.
(d) New trees.
(1) New streets. The applicant shall plant shade or ornamental trees along both sides of all new streets. Such trees shall be spaced not more than 50 feet apart on each side of the street off the city right-of-way. Such trees shall be at least two inches in caliper.
(2) Developer shall be encouraged but not required to plant trees in addition to those required under subsection (d)(1) of this section.
(e) Waiver. The requirements of this section 74-44 may be waived, in whole or in part, by the city council in one or more of the following circumstances:
(1) To allow for the reasonable development of areas devoid of woody materials, dedicated school sites, playing fields and other non-wooded recreation areas, and other facilities and uses of a similar nature.
(2) To allow for the preservation of wetlands.
(3) When strict application of the requirements would result in unnecessary or unreasonable hardship to the developer as provided in section 74-126 of this chapter.
