A.

Purpose and Intent. The purpose of this Article is to promote site planning that furthers the preservation of mature trees and natural areas, to protect trees during construction; to facilitate site design and construction that contribute to the long term viability of existing trees; and to control the removal of trees when necessary. It is the further purpose of this Article to achieve the following broader objectives:

1.

Prohibit the indiscriminate clearing of property.

2.

Achieve the City's Future Land Use Plan goals as set by citizens through the appointed boards and the City Council.

3.

Maintain and enhance property values and a positive image for the attraction of new residents and business enterprises to the City.

4.

Protect healthy quality trees that contribute to noise reduction, air quality, glare reduction, and promote the natural ecological environmental and aesthetic qualities of the City.

5.

Promote site planning that is sensitive to the location of existing trees in an effort to save quality trees evenly distributed across the City to reduce the need to overplant public property.

6.

Provide for a permitting and enforcement procedure.

B.

Tree Removal Permit Required.

1.

The clear-cutting of land as defined in this Code is prohibited and all permits for tree removal shall be subject to this Code (see Section 10.02 - Exhibit B).

2.

No grading or tree removal shall take place on any undeveloped property without obtaining a tree removal permit unless exempted by this Code.

3.

All trees not listed as a protected tree within this Code may be removed with a tree removal permit.

4.

The removal of selected trees from within a densely forested area when done in a professionally accepted manner shall be allowed as a single permit upon approval by the Development Review Committee. Approval will only be granted when it is determined that the selective thinning is being done in a manner that would enhance the environment and likelihood of survival for the remaining trees.

5.

Where protected tree removal is allowed through exemption or by a tree removal permit and the root system is intertwined with protected trees which are intended to be saved, the tree shall be removed by flush cutting with the natural level of the surrounding ground. Where stump removal is also desired, stump grinding shall be allowed, or upon approval of the City, a trench may be cut between the two trees sufficient to cut the roots near the tree to be removed, thereby allowing removal of the remaining stump without destruction of the root system of the saved tree.

C.

Requirements for New Developments. All projects/developments that have not submitted final plat/construction plans, site plan or building permit, whichever is applicable, as of the effective date of this Code shall be subject to the requirements for tree protection and replacement specified herein. Approval of development plans for compliance with this Code may be by the City Council, Planning and Zoning Commission, or City Staff, whichever is applicable by City regulations. Developer must demonstrate that all options have been considered to preserve as many trees as possible in accordance with this Code.

h.

Any other factors deemed to be in the interest of preserving or protecting the health, safety and welfare of the City of Keller and its citizens.

I.

Tree Replacement Requirements.

1.

In the event that it is necessary to remove a protected tree as specified in this Code, the party removing the tree shall be required to replace the protected trees being removed with quality trees as defined herein (see Section 10.02 - Exhibit I). A sufficient number of trees shall be planted to equal or exceed the diameter (measured at eighteen inches (18") above ground level of each tree removed. This mitigative measure is not meant to supplant good site planning. Tree replacement will be considered only after all design alternatives, which could save more existing trees, have been evaluated and reasonably rejected. Said replacement trees shall be a minimum of three-inch (3") diameter (measured at eighteen inches [18"] above ground) and seven feet (7') in height when planted.

2.

At the time of review, the agent responsible for placement, the time of replacement, and the location of the new trees will be determined by the Development Review Committee. The replacement trees shall be located on the same property that trees were removed whenever possible. However, if this is not feasible, they may be placed on a designated property as agreed to by the Planning and Zoning Commission. If the Planning and Zoning Commission approves the planting of replacement trees more than thirty (30) days after the removal of protected trees, the applicant shall provide the Community Development Department with an affidavit that all replacement trees will be planted within six (6) months. A replacement tree that dies within two (2) years of the date it was planted must be replaced by another replacement tree in compliance with this Code.

3.

The applicant may request from the Planning and Zoning Commission for recommendation to the City Council to make a payment into the Tree Reforestation Fund in lieu of planting the replacement trees if planting is not feasible. The funds shall be used only for purchasing and planting trees on public property or acquiring wooded property that shall remain in a naturalistic state in perpetuity. The fee payment amount shall be established in the City's Fee Schedule. The schedule may be periodically updated by the City without changing this Code. (Amended by Ord. No. 1818 on October 18, 2016)

J.

Tree Transplantation. The City may request to enter a property following the approval of a tree removal permit, or development plans for a property to inspect the site for any trees marked for removal that may be transplanted. The City will pay all costs associated with the removal and transplantation of designated trees to public parks, public facilities or public rights-of-way.

K.

Tree Protection. A major purpose of this Code is to protect all protected trees, which are not required to be removed, to allow approved construction to occur. The following procedures are required:

1.

All construction plans shall include the necessary documents as requested by the Development Review Committee to review the tree preservation plan.

2.

The following activities shall be prohibited within the limits of the critical root zone of any protected tree subject to the requirements of this Code.

a.

Material Storage: No materials intended for use in construction or waste materials accumulated due to excavation or demolition shall be placed within the limits of the critical root zone of any protected tree. However, this restriction shall not apply to material storage in areas exempt from the tree protection and replacement requirements (e.g., building pad, driveway, patios, parking lot, etc.)

b.

Equipment Cleaning/Liquid Disposal: No equipment shall be cleaned or other liquids deposited or allowed to flow overland within the limits of the critical root zone of a protected tree. This includes, without limitation, paint, oil, solvents, asphalt, concrete, mortar or similar materials.

c.

Tree Attachments: No signs, wires or other attachments, other than those of a protective nature, shall be attached to any protected tree. Fencing attached to a tree via "U" nails or bent nails when only at points of tangency with the trees are allowed.

d.

Vehicular Traffic: No vehicular and/or construction equipment traffic or parking shall take place within the limits of the critical root zone of any protected tree other than on an existing street pavement. This restriction does not apply to single incident access within the critical root zone for purposes of clearing underbrush, establishing the building pad and associated lot grading, vehicular traffic necessary for routine utility maintenance or emergency restoration of utility service or routine mowing operations.

e.

Grade Changes: No grade changes shall be allowed within the limits of the critical root zone of any protected tree unless adequate construction methods are approved by the Development Review Committee or if grading is as directed by the City's drainage inspector.

f.

Impervious Paving: No paving with asphalt, concrete or other impervious materials in a manner that may reasonably be expected to kill a tree shall be placed within the limits of the critical root zone of a protected tree. If a protected tree die within five (5) years of issuance of a Certificate of Occupancy for non-residential construction or final building inspection for residential construction, due to construction activity or impervious paving around the critical root zone of the tree, the property owner shall submit a mitigation plan and tree replacement in accordance with this Code shall be required.

3.

A protected tree shall be considered to be preserved only if a minimum of seventy-five percent (75%) of the critical root zone is maintained at undisturbed natural grade and no more than twenty-five percent (25%) of the canopy is removed due to building encroachment.

4.

The following procedures shall be followed on all types on construction projects (i.e. residential subdivisions, commercial, multi-family, industrial developments, residential builders and municipal/public).

a.

Tree Flagging or Marking: Trees that are shown on an approved plan by the City for preservation/protection shall be flagged with bright fluorescent orange vinyl tape or ribbon wrapped around the main trunk at a height of four and one-half feet (4.5') or more such that it is very visible to workers operating construction equipment. Trees that are marked for preservation/protection shall have protective fencing in accordance with the requirements of this Code.

b.

Protective Fencing: In those situations where a protected tree is so close to the construction area that construction equipment might infringe on the root system or is within twenty feet (20') of the construction area, a protective fencing shall be required between the outer limits of the critical root zone of the tree and the construction activity area. Four feet (4') high protective fencing shall be supported at a maximum of ten feet (10') intervals by approved methods. At regular intervals, signs shall be required that states in English and in Spanish, "Tree Protection Area. No grading, parking vehicles, or storing equipment permitted. Violators may be fined." All protective fencing shall be in place prior to commencement of any major site work involving heavy equipment for construction of utilities and roadways and shall remain in place until all site work has been completed. This provision does not apply to clearing the right-of-way for the purpose of access to the site for site preparation. (Amended by Ord. No. 1818 on October 18, 2016)

c.

Protective fencing shall not be required for clearing the rights-of-way for the purpose of access to the site. Once the site is accessible by heavy equipment, protective fencing shall be placed in accordance with this Code.

L.

Tree Pruning Restrictions. No protected tree shall be pruned in a manner that significantly disfigures the tree or in a manner that would reasonably lead to the death of the tree.

1.

Allowed Pruning: Protected trees may be strategically pruned to allow construction or demolition of a structure. All pruning shall take place in accordance with approved Arboricultural techniques and the recommendations of Exhibit G. Reasonable pruning of trees also may be performed or contracted to be performed by the owner of the tree when unrelated to construction activity.

2.

Required Pruning: The owners of all large trees (as defined in Section 10.02) adjacent to a public right-of-way shall be required to maintain a minimum clearance of fifteen feet (15') above the traveled pavement or curb of a public street. Said owners shall also remove all dead, diseased or dangerous trees, or broken or decayed limbs that constitute a menace to the safety of the public. The City shall also have the right to prune trees overhanging within public a right-of-way that interfere with the proper spread of light along the street from a street light or interfere with visibility of any traffic control device or sign or as necessary to preserve the public safety.

3.

Tree Topping: It shall be unlawful as a normal practice for any person, firm, or City department to top any street tree, park tree or other tree on public property. Trees severely damaged by storms or other causes, or certain trees under utility wires or other obstructions where other pruning practices are impractical may be exempted from this Code at the determination of the City.

M.

Tree Planting Restrictions.

1.

Overhead Lines: Any required replacement trees shall not be planted within an area such that the mature canopy of the tree will be within ten feet (10') of overhead utility lines.

2.

Underground Utilities: Any required replacement trees or street trees shall not be planted within five feet (5') of underground public utility lines, including water lines, sewer lines, transmission lines or other utilities. No trees may be planted within five feet (5') of a fire hydrant.

3.

Street Corners: No street tree shall be planted closer than twenty-five feet (25') of any street corner, measured from the point of nearest intersecting curbs or curb lines.

N.

Enforcement.

1.

Permit Required: No development or grading activity shall commence until all applicable requirements of this Code are met and a notice to proceed or a tree removal permit has been issued for the site.

2.

Acceptance of Improvements: No acceptance of public improvements shall be authorized until it is determined that all requirements of this Code are met and all fines for violations of this Code have been paid to the City or otherwise disposed of through the Municipal Court. No acceptance of public improvements shall be authorized until all replacement trees have been planted or appropriate payments have been made to the Tree Reforestation Fund.

3.

No Certificate of Occupancy shall be issued until all replacement trees have been planted or appropriate payments have been made to the Tree Mitigation Fund.

4.

Notwithstanding the above provisions, public improvements may be accepted and Certificate of Occupancy may be issued before all trees have been replaced if an escrow account is established by the City in the amount equal to the prevailing rate for installed trees with a two (2) year guarantee, plus fifteen percent (15%) to cover administrative costs.

O.

Penalty.

1.

Any person, firm, corporation, agent, or employee thereof who violates the provisions of this Code by removing trees without a permit shall be guilty of a misdemeanor and upon conviction hereof shall be fined in an amount not to exceed two hundred and fifty dollars ($250.00) per caliper inch of the tree(s) removed or damaged not to exceed two thousand dollars ($2,000) per incident.
