ARTICLE 10

13 LANDSCAPING AND TREE PRESERVATION 1

[1]
Editor’s note–Former article 10.13 pertaining to landscaping and tree preservation was repealed and replaced with similar provisions by Ordinance 2023-19 adopted 9/11/2023. Prior to the deletion, this article derived from the following: Ordinance 2015-11 adopted 3/23/15; 2010 Code, secs. 38-118; 38-140–38-159; Ordinance 2018-06 adopted 3/12/18; Ordinance 2019-12 adopted 4/22/19.

§ 10.13.001 In general.

The purpose of this article is to establish requirements to enhance the community's ecological, environmental, and beautification efforts as well as its aesthetic qualities. It is the intent of this article to reduce the negative effects of glare, noise, erosion, and sedimentation caused by expanses of impervious and unvegetated surfaces within the urban environment. It is the intent of this article to preserve and improve the natural and urban environment by recognizing that the use of landscaping elements can contribute to the processes of air purification, oxygen regeneration, groundwater recharge, noise abatement, glare and heat reduction, and provision of habitats for wildlife, and enhance the overall beauty of the city. The city recognizes the value of creating attractive corridors through the city and for creating usable open spaces during the subdivision and site planning processes to provide opportunities for hike and bikeways, greenbelts and the preservation of floodplains in a natural condition where practical to add community value.

§ 10.13.004 Tree preservation.

Tree preservation requirements. The provisions of this section shall apply to all developments, including commercial, industrial, single-family and multifamily residential, and all other development in the corporate limits of the city.
(1) 
In general.
(A) 
Purpose and intent.
The purpose of these requirements is to encourage the preservation of mature trees, and preservation of protected trees during construction and land development. It is the intent of these regulations to achieve the following:
(i) 
Prohibit the indiscriminate clearing of property.
(ii) 
Protect and increase the value of residential and commercial properties within the city.
(iii) 
Maintain and enhance a positive image for the attraction of new business enterprises to the city.
(iv) 
Protect healthy quality trees and promote the natural ecological environmental and aesthetic qualities of the city.
(v) 
Help provide needed shaded areas in order to provide relief from the heat by reducing the ambient temperature.
(B) 
Applicability.
(i) 
Developments for which a plat, site plan or master plan (land study) has not yet been submitted as of the effective date of this article shall be subject to the requirements for tree protection specified herein.
(ii) 
Protected tree. A "protected tree" shall be any existing tree of a species or type listed on the city's protected tree list and that has or possesses each of the following characteristics or criteria:
a. 
A single trunk of 6 inches in caliper width or greater, measured at 12 inches above natural grade level, and at least 8 feet high; or a multi-trunk having a total caliper width of 8 inches, measured by combining the caliper width of the largest stem or branch with 1/2 the caliper width of each additional stem or branch, all measured at 12 inches above natural grade level, and at least 12 feet high; and
b. 
Located outside of a public street, alley, right-of-way, utility easement, drainage easement, fence easement, pedestrian access easement, or other public right-of-way or easement; or the buildable area of a building lot or site, as included on a record plat approved by the city council and filed in the plat records of the county; or the buildable area of a building lot or site, as included on a building permit site plan approved by the city. For the purposes of any development of a building lot or site 1 acre in area or larger, "buildable area" shall mean all that portion of the building lot or site inclusive of the footprint of the building(s) and projected 10 feet from the outside of the building footprint. For the purposes of any development of a building lot or site less than 1 acre in area, "buildable area" shall mean that portion of the building lot or site not within the required front yard, side yard and rear yard areas. For the purposes of issuing building permits, "buildable area" shall also mean those areas on a building lot or site, as shown on the required site plan, necessary for the construction of such other improvements as pools, tennis courts and accessory buildings, excluding driveways and parking lots and including sufficient adjacent area to allow for the normal operation of construction equipment.
(iii) 
Exceptions. The replacement of preserved tree provisions of this article shall not be required under any of the following circumstances:
a. 
Minor/admin, preliminary, final or amending plats not associated with development plans
b. 
Damaged/diseased trees. The tree is dead, diseased, damaged beyond the point of recovery, in danger of falling, or endangers the public health, welfare or safety as determined by the city.
c. 
Utility service interruption. The tree has disrupted a public utility service due to a tornado, storm, flood or other act of nature. Removal may be limited to the portion of the tree reasonably necessary to reestablish and maintain reliable utility service.
d. 
Business interests. The following business ventures shall be exempt from the requirements specified herein as follows:
1. 
Landscape nurseries.
All licensed plant or tree nurseries shall be exempt from the tree protection and replacement requirements and from the tree removal permit requirements only in relation to those trees planted and growing on the premises which are so planted and growing for the sale to the general public.
2. 
Golf courses.
Golf courses shall be exempt from the tree protection and replacement requirements and from the tree removal permit requirements for removal of protected trees within areas designated as tee boxes, fairways or greens. All other areas shall be subject to these requirements.
(2) 
Protection and replacement of existing trees.
(A) 
General standards.
(i) 
Damaging trees.
The following acts are unlawful:
a. 
Damage, cut, carve, transplant or remove any trees on city property;
b. 
Attach a rope, nail, advertising poster, sign or other contrivance to any city tree;
c. 
Allow any gaseous liquid or solid substance harmful to trees to come into contact with city trees; or
d. 
Set or permit any fire to burn when such fire, or the heat from such fire, will injure any tree.
(ii) 
No person, directly or indirectly, shall cut down, destroy, remove or move, or effectively destroy through damaging, any protected tree situated on property regulated by this article, except as follows:
a. 
Right-of-way owned or leased by a governmental entity as of the effective date of this article.
b. 
Property owned or leased by a public utility, excluding property used for administration offices or functions.
(iii) 
Improvements shall be designed, whenever reasonably possible, to preserve a protected tree. The building official, upon receiving qualified professional advice, may approve a landscape plan that provides for the removal of a protected tree when determined that the development cannot reasonably preserve the protected tree.
(iv) 
If the building official approves the removal of a protected tree, the landscape plan must provide for the planting of 1 replacement trees of like type for each protected tree to be removed if it is determined this will not result in overcrowding. Such replacement trees shall be in addition to any other trees required to be planted under this article.
(v) 
Whenever one or more existing trees, whether protected trees or otherwise, or existing shrubs provide an effective and desirable buffer or screen for a proposed use or development, the building official may require that all or some of the existing trees or shrubs be preserved if the preservation can be accomplished without undue interference with the development of the premises. The building official will credit any existing trees or shrubs which are preserved against any requirements for trees, shrubs or screening as provided in this article, if the preserved trees or shrubs substantially serve the purpose of the requirement.
(vi) 
Use of retaining walls to preserve trees. When using a retaining wall when natural grade must be raised or lowered, the tree well shall be designed in accordance with the design concepts depicted below:
10Tree.tif
(vii) 
Site plans should accommodate existing trees by providing islands in parking lots, grading, and landscaping surrounding structures. In commercial, multifamily, and other developments, trees will be added to the landscape, as necessary, to meet the minimum landscape requirements of this article. The clustering of trees, in lieu of small landscaping islands, shall be permitted.
(B) 
Preservation incentives.
If removal of a protected tree is proposed due to efforts to comply with other provisions of this code, the applicant may request that the building official or other designated staff consider the following preservation incentives in exchange for the nonremoval and preservation of the protected tree:
(i) 
Tree preservation credit.
Landscape plans that preserve existing trees found on the approved list of qualified trees shall be given credit toward the total number of trees required as shown below:
Caliper of Existing Tree
Credit Against Tree Requirement
1"–3"
2.0 trees
3-1/2"–9"
3.0 trees
9-1/2"–15"
5.0 trees
15-1/2" or greater
10.0 trees
(ii) 
Parking space reductions.
Reduction in the minimum parking requirements as necessary to save and/or properly protect a protected tree.
(iii) 
Sidewalks.
Modification to sidewalks, their location and possibly the width and curb requirements as necessary to facilitate protecting a protected tree.
(C) 
Replacement of protected trees.
(i) 
Developers and owners subdividing property for development must submit a tree preservation plan with their site development plan.
(ii) 
Upon determining the number, size and location of any protected trees, the developer or subdivider must identify which of those protected trees can be preserved and which are proposed to be removed. A tree plan or survey showing protected trees shall be submitted with the site plan. The burden shall be upon the applicant to show the necessity for any protected tree to be removed.
(iii) 
When a protected tree is proposed to be removed, staff shall endeavor to seek any practical design solution that may be available in order to preserve any protected tree. If a design solution should necessitate the need for a variance from any requirement of the city code, the board of adjustments shall have the authority to grant a variance upon determining that the preservation of the tree is in the public interest and that the variance proposal would not result in health or safety issues.
(iv) 
When design solutions are not available to preserve protected trees, the developer or subdivider shall be required to determine the composite caliper of the protected trees proposed to be removed. The composite caliper of protected trees to be removed shall be multiplied by 50 percent to determine the aggregate amount of tree caliper that must be installed to replace protected trees to be removed. The developer or subdivider shall have the option to either: a. preserve mature nonprotected trees or b. replace the protected trees species with the planting of many small protected trees, a few protected trees or a single protected tree. For either option, the aggregate replacement caliper must be equal to or greater than the existing aggregate caliper of protected trees to be removed. For site plans, the aggregate caliper for replacement trees shall be counted toward fulfillment of the normal landscaping requirements of this article. This requirement must not be interpreted to result in over-planting tree density when mature size of replacement trees is considered.
(v) 
For subdivisions, the aggregate caliper for replacement protected trees shall be in addition to the normal landscaping requirements of the city code. To the greatest extent practical, protected and replacement trees should be located in common areas, greenbelts, or a part of a sedimentation and erosion control buffer to ensure the long-term tree health and maintenance without overcrowding.
(D) 
Tree protection during construction.
Tree protection improvements will be installed before any site work is initiated and shall be maintained for the duration of construction. Tree protection will consist of the following:
(i) 
It will consist of fencing (orange mesh or chainlink) placed around the protected root zone.
(ii) 
No vehicles or construction materials/debris will be allowed in the protected root zone.
(iii) 
No equipment shall be cleaned or other liquids deposited within the limits of the dripline of any protected tree. This includes, but is not limited to, paint, oil, solvents, asphalt, concrete, mortar or other materials.
(iv) 
No signs, wires, or other attachments, other than those of a protective nature, shall be attached to any protected tree.
(v) 
Trespassing or throwing trash into a protective fence area is prohibited.
(vi) 
Any damage done to tree crowns or roots will be repaired immediately and any wounds on oak or pecan trees will be painted with pruning paint within 60 minutes to prevent disease or infestation to the tree.
(vii) 
Wells or retaining walls around the protected root zone will be used if proposed finished grades will raise or lower the natural protected root zone grade by more than six inches.
(viii) 
The finished protected root zone will be pervious.
(ix) 
For commercial, multifamily and other developments: a minimum of 25 percent of the total caliper must be preserved.
(x) 
For single-family residential development of single or contiguous lots: contiguous lots include three or more lots, a minimum of 50 percent of total caliper must be preserved.
(xi) 
Utility and flatwork per the original builder's plan are exempt for up to 30 percent of the protected root zone. (Any work in the protected root zone must be approved by the inspections department.)
