[HISTORY: Adopted by the Town Board of the Town of Greenburgh 12-19-2019 by L.L. No. 1-2020.[1]Amendments noted where applicable.]
[1]
Editor's Note: This ordinance also repealed former Ch. 260, Trees, adopted 12-18-1991 by L.L. No. 39-1991, as amended.
A. 
Trees are necessary to protect the health, safety, environment, ecosystems and general welfare of the inhabitants and properties in the Town of Greenburgh. The Town recognizes that preservation of the environment is the responsibility of the entire community. Trees provide oxygen, impede soil erosion, aid water absorption, ameliorate against potential flooding, and absorb CO2 and other pollutants and breathable particulate matter; provide shade, screening, privacy, green space and aesthetic appeal; absorb and lessen impacts from winds and act as natural noise barriers; and provide other environmental benefits and generally enhance the quality of life and values of properties within the Town.
B. 
The intent of this chapter is to regulate the quantity, quality, canopy, and distribution of trees within the Town of Greenburgh, as prescribed herein. In implementation thereof, the purpose of this chapter is to regulate the quantity of healthy trees within the community through the establishment of tree replacement standards, to regulate the quality and canopy of trees through adoption of technical standards and specifications for species selection and diversity, tree planting, tree maintenance, and tree protection, and to regulate the distribution of trees so that their function is maximized.

Endangering the owner or property of the owner.
(c) 
Endangering an adjoining property owner or the property of an adjoining property owner.
(2) 
The condition and species of the tree with respect to overall health, disease, insect attack, damage, interference and potential interference with utility services, and proximity to existing trees, existing structures or proposed structures.
(3) 
The environmental impact of the tree removal, including, but not limited to, the effect of the tree removal on erosion, soil moisture retention, steep slopes, flow of surface waters and drainage, CO2 and breathable particulate removal, ecosystems supporting wildlife, or any other environmental factor, and the aesthetic composition of the land and surrounding area.
(4) 
The necessity of the tree removal in order to achieve the applicant's goals, including, but not limited to, whether the location of the tree prevents the property owner from undertaking otherwise proposed construction or alteration (including, but not limited to, teardowns, renovations and/or expansions) and the possible or practicable alternatives to the tree removal, including relocation of improvements.
(5) 
Whether the proposed tree removal will cause injury to, cut, damage, destroy or remove more trees than is reasonably necessary to achieve the goals of the applicant, or is inconsistent with the stated purposes of this chapter and the standards and specifications in this section and in the Town of Greenburgh Tree Technical Manual.
(6) 
Considerations of land use and the general welfare and overall environment of the area.
(7) 
The species of the tree and whether any tree in question is a tree worthy of preservation due to unusual characteristics such as age, history, size, rarity, financial value, visual importance to the neighborhood, or being located within a Conservation District zone as defined in § 285-9 et seq.
B. 
The following standards are required to be met in order to grant, or grant with conditions, a tree removal permit for a tree or trees under this chapter:
(1) 
Tree Replacement:
(a) 
Replacement trees shall be planted on site equal to at least 90% of the environmental value of the trees proposed to be removed; provided that, if the property is an Undeveloped Forested Property and the permit is sought in connection with a building permit to build a commercial facility or a residence or residences, or in connection with any site plan approval, then the environmental value of the replacement trees planted on site shall be equal to at least 30% of the environmental value of the trees proposed to be removed.
(b) 
The environmental value of removed and replacement trees shall be determined by using the iTree methodology on the U.S. Forest Service website, the National Tree Benefit Calculator on the Arbor Day Foundation website, or other methodology selected by the applicant and deemed acceptable by the Forestry Officer. In calculating the percentages specified above, the applicant shall take into account the environmental values (gallons of stormwater absorption, and pounds of CO2 removal) of the replacement trees as of when they reach mid-maturity. All new trees to be planted must be selected from the Town of Greenburgh Official Replacement Planting List. At least 50% of the replacement trees shall be native trees, as identified in the Town of Greenburgh Official Replacement Planting List. The location of the replacement trees shall be satisfactory to the Approval Authority, who shall take into consideration the topography of the site and the potential for stormwater runoff onto other properties and public streets.
(c) 
All replacement trees shall be shown on a landscape plan acceptable to the Approval Authority, which shall consider the total number of trees proposed for removal and other relevant factors such as the topography of the area where trees are proposed for removal. Replacement trees shall be a minimum 1.5-inch caliper size for deciduous trees, and five feet in height for coniferous (evergreen) trees, unless the Forestry Officer provides a waiver or permits modifications to minimum size standards due to topography or other conditions of the property. If and to the extent the Approval Authority determines that one or more trees required to be planted as replacement trees cannot be planted due to shallow soil conditions on the property, property size or like prohibitive conditions, alternate plantings of shrubs on site satisfactory to the Forestry Officer to fulfill the legislative intent of this chapter may be made.
(d) 
Planting of replacement trees are not required if and to the extent the Approval Authority determines that the removal of trees on a property is required as part of good forestry practice to improve the health of remaining trees. Planting of replacement trees are not required to replace trees removed pursuant to § 260-5. Planting of replacement trees are not required to replace invasive species of trees which are removed, and in no event shall any invasive species of trees or plants be planted as replacements.
(e) 
If an applicant has violated this chapter and is seeking a tree removal permit, the replacement tree standard is 120% of the environmental value of the trees cut down, removed, topped, excessively pruned, injured, damaged, wounded, broken, killed or destroyed, or, depending on site characteristics, such other percentage deemed acceptable to the Forestry Officer.
(2) 
In order to increase the diversity of the age, genera and species in the community tree canopy, consideration shall be given to preserve mature trees and trees of significance, and to plant trees and shrubs on sites where the tree population is predominantly over mature and in the last quarter of its lifecycle. When selecting plant material for a landscape site plan, to achieve a variety of interest in form, color and height, and to reduce the opportunity for a pest or disease outbreak generally associated with the planting of monocultures, the following table shall be utilized:

(3) 
The Forestry Officer shall have the authority to waive or permit modifications to the above requirements, based on the characteristics of the subject property and surrounding properties.
(4) 
If a tree to be cut and removed is in excess of 12 inches DBH (37.5 inches in circumference) or 30 feet in height, a Licensed Professional Tree Care Company must be used to perform the cutting and removal. The Forestry Officer may waive such requirement in writing if the fall zone is more than 30 feet away from any principal or accessory structure on any adjoining property. Prior to permit issuance, the applicant shall provide the Licensed Professional Tree Care Company's name, address, telephone number, name of job manager, certificate of liability insurance naming "Town of Greenburgh" as additionally insured, and a copy of their New York State Workers Compensation insurance. A contractor may be used where the tree removal is part of an approved permit issued by any Board or Officer of the Town and the contractor is approved for tree removal by the Forestry Officer, provided the information outlined above is submitted in full.
C. 
If an applicant proposes the removal of 10 or more trees as part of any application (not including invasive species), the Approval Authority is hereby authorized and empowered to obtain the assistance, when necessary, of a professional consultant selected by it, especially qualified by reason of training or experience in tree assessment, valuation, planting, preservation and landscaping or landscape architecture or engineering, at the applicant's expense (and with 10 days prior notice to the applicant), which expense shall be reasonable and customary for such services, in order to fully evaluate a tree removal permit application, and carry out any requirements or conditions of a permit issued under this chapter.
D. 
If a tree approved for removal is subject to § 260-4A(2), pertaining to trees within a wetland, watercourse or adjacent buffer area, or within an excessively steep slope, whatever additional standards are applicable under Chapter 280 and/or Chapter 245, as appropriate, to disturbances within such regulated areas, are required to be complied with in order for a tree removal permit to be issued.
E. 
If a tree approved for removal is subject to § 260-4A(3), pertaining to trees designated by the New York State Department of Environmental Conservation as a protected native plant, the environmental value of such tree must be replaced by a native tree or trees and additionally any permit must be subject to any and all approvals required by the New York State Department of Environmental Conservation.
F. 
The property owner shall warrant that all replacement plantings shall survive and be in a healthy state on the third anniversary of the date on which the replacement plantings have been provisionally accepted by the Forestry Officer, or designee, as complying with the permit conditions.

Landscape Site Plans shall be prepared by a registered landscape architect or appropriate licensed professional, and submitted to the Approval Authority for acceptance prior to a tree removal permit application being reviewed, in connection with all commercial properties, all residential development projects, and when more than 10 trees on any property are proposed for removal. The Forestry Officer may waive such site plan requirement, in the event, taking into account all trees removed from such property within the preceding five-year period, the aggregate tree removal proposed is less than 24 inches DBH (75 inches in circumference) and may in other circumstances s/he deems appropriate given the health and condition of the tree(s) and the relevant topography, whereby a written letter outlining all proposed landscaping may be submitted in the absence of a landscape site plan.
(a) 
Replacement plantings to be located in landscape strips, parking lot islands, environmentally sensitive areas such as wetlands, watercourses, adjacent buffer areas and on areas of slope greater than 15% shall be distributed over their entire lengths and widths.
(b) 
Landscaping may be arranged symmetrically (formal) or asymmetrically (informal) and shall be grouped to form plant clusters when practicable. Informal groupings which reflect the natural character of the region are encouraged.
J. 
All replacement plantings shall be planted and maintained according to the specifications outlined in the Town of Greenburgh Tree Technical Manual (available on the Town website), and shall retain their plant identification tag until a final inspection is conducted by the Town.

Upon completion of all protection, replanting and restoration work to the satisfaction of the Approval Authority, the performance bond shall be canceled and replaced with a maintenance bond to be approved by the Town Attorney and to run for a term of three full growing seasons. The growing season for Westchester County is April through November. The 10% cash in escrow shall remain on deposit with the Town until the maintenance bond is canceled. If new trees or shrubs planted as part of the restoration work do not survive three full growing seasons, they shall be replaced in-kind, and the term of the maintenance bond shall be extended to run for a term of three full growing seasons from the time any necessary replanting has taken place, to the satisfaction of the Forestry Officer.
