(a) 
This division is adopted to promote and enhance a superior community environment, to maintain the rural character, to maintain air quality and ecologic balance, to maintain property values, to provide soil stabilization, to filter stormwater runoff, and to ensure the maximum preservation of the valuable natural features and scenic rural/wooded character as contemplated in the master plan of the city by establishing minimum standards and requirements relating to the protection of trees and natural vegetation.
(b) 
It is intended that this division be administered with the foregoing purposes in mind and specifically so as to:
(1) 
Ensure, insofar as practical in permitting development of land and minimizing fire hazard, the maximum retention of natural vegetation to aid in protection against erosion of top soil, preservation of natural scenic qualities and healthy ecosystems of the city through good conservation practices, protection from flooding or landslides, noise absorption, maintenance of privacy, and in providing habitat, shade and color;
(2) 
Protect mature trees and significant stands of trees in order to retain as many as possible consistent with the purposes set forth herein and also consistent with reasonable economic enjoyment of private property. In this context, privately owned trees have an impact on the quality of life for the entire community;
(3) 
Preserve the rugged beauty and natural environment that defines the character of the city and makes it a unique and desirable community; and
(4) 
Require the removal of all confirmed dead brush, vegetation, and trees from all properties in order to reduce the risk of wildfire. In the case of dead trees and dead understory, the city inspector must confirm that the vegetation is indeed dead prior to its removal in order for the owner to avoid replacement requirements as described in section 22.03.304(d) below.
(Ordinance 2022-007 adopted 4/13/22)
Ashe Juniper.
Juniperus ashei (commonly known as Cedar, Post Cedar, Mountain Cedar, or Blueberry Juniper) is a native, drought-tolerant evergreen shrub or small tree.
Canopy.
For forests the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees.
Fire safety buffer zone (FSBZ).
A concept of defensible space in a wildland-urban interface (WUI) created around the perimeter of a structure to reduce the risk that fire will spread from the surroundings to the structure as well as from the structure to the surroundings and provide firefighters access and a safer area to defend.
Firescaping.
Is landscape design that reduces house and property vulnerability to wildfire. The goal is to develop a landscape with a design and choice of plants that offers the best fire protection and enhances the property. The idea is to surround the house with things that are less likely to burn. It is imperative when building homes in wildfire-prone areas that fire safety be a major factor in landscape design. Appropriate manipulation of the landscape can make a significant contribution toward wildfire survival.
Fuel ladder effect.
A firefighting term for live or dead vegetation that allows a fire to climb up from the landscape or forest floor into the tree canopy; common fuel ladders include tall grasses, shrubs, and tree branches i.e. understory, both living and dead. It is also part of defensible space firescaping practices.
Imminent or immediate threat to persons or property.
A tree, trees, or part of a tree that poses an imminent or immediate threat of injury to persons or damage or destruction to property as determined by the city inspector or city administrator.
Limbing-up.
To cut or lop live or dead branches of a tree to raise its crown or canopy in order to manage fuel ladder affect of a ground fire to the canopy.
Non-native invasive species.
(Also called “non-indigenous,” “non-native” or “alien”) exotic pest plants and invasive exotics growing in native plant communities that adversely affect the wild life habitats and bioregions they invade, economically, environmentally, and/or ecologically. Examples of the most troublesome non-native invasive species trees and plants in our area as identified by the City of Austin are as follows (ref: http://www.austintexas.gov/invasives):

(Ordinance 2022-007 adopted 4/13/22)
(a) 
Landscape shall be preserved in its natural state to the greatest extent possible.
(b) 
Vegetative screening shall be maintained to the greatest extent possible, especially along the perimeter of all properties in order to maximize the screening and buffering of structures, driveways and parking areas from adjacent properties.
(c) 
Structures, driveways, and parking areas shall be designed and located to fit harmoniously with the natural terrain and to minimize the necessity for removing trees, vegetation, and soil, or the addition of fill.
(d) 
It is unlawful for any property owner or tenant to harbor dead trees, dead vegetation, dead brush piles, and other flammable dead organic material on their property. Exceptions would be allowed for contained compost piles and stacked and stored firewood. In order to reduce the risk of fire on all properties, all dead trees and brush piles, and other flammable dead organic material shall be cleared and removed in accordance with section 22.03.303 below. In the case of dead trees and understory, the city inspector must confirm that the vegetation is dead prior to its removal in order for the owner to avoid replacement requirements as described in section 22.03.304(d) below. Any person, corporation, or entity who or which violates this subsection commits a class C misdemeanor and, upon conviction, shall be fined in an amount not to exceed $2.000.00. Each day in which any violation shall occur, or each occurrence of any violation, shall constitute a separate offense.
(e) 
The city is responsible for all vegetation and trees that are located on city-owned property.
(Ordinance 2022-007 adopted 4/13/22)

(4) 
Fire safety buffer zone.
(A) 
Trees less than twelve (12) inches in diameter (as measured at a point fifty-four (54) inches above the ground) and understory vegetation to establish a "fire safety buffer zone" (FSBZ) as part of firescaping according to Firewise Landscape Design and the Texas Forest Service at Texas A&M, which is defined as an area of land extending up to thirty (30) feet from the perimeter of habitable structures established for fire prevention purposes.
(B) 
This FSBZ may be expanded, upon approval of the city inspector, to include an area up to one hundred (100) feet from the perimeter of habitable structures for those lots having down slopes in excess of 25% below the habitable structure only for the removal of Ashe Junipers (commonly referred to as "cedars") if less than twelve (12) inches in diameter as measured at a point fifty-four (54) inches above the ground.
(C) 
Trees removed to establish a FSBZ, as described in this subsection, do not require replacement, except:

(5) 
Non-native invasive species tree(s) or plant(s).
Non-native invasive species trees, plants and shrubs do not require replacement as long as the city arborist/inspector identifies them as such and stipulates that no adverse effect of erosion will occur from the removal. In the case of non-native invasive shrubs or understory that serve as understory vegetative screening at external perimeter of property, the city inspector may require replacement native vegetative screening to be installed along the periphery of the property when, at the city inspector's discretion, the screening is necessary and reasonable to mitigate the community impact of the loss of the removal and to maintain the rural feel of the neighborhood.
(6) 
When removing live conifers and Juniperus species (commonly referred to as "cedars") of three (3) inches in diameter or less as measured at a point fifty-four (54) inches above the ground as a fire prevention measure whether inside or outside of a fire safety buffer zone. Trees removed in accordance with this subsection do not require replacement.
(7) 
When removing diseased, dying or dead trees, or a tree that poses an imminent or immediate threat to persons or property as determined by the city inspector or city administrator, under the following conditions:
(A) 
The property owner must submit a request for the permit to the city inspector specifying the affected species, location, and trunk diameter, including a description of the threat if applicable.
(B) 
If the city inspector concurs with the property owner's assessment of the condition of the tree, then the permit shall be issued.
(C) 
If the city inspector does not concur with the property owner's assessment of the condition of the tree, then the property owner shall have the right to submit a signed letter from a certified arborist identifying the specific disease, condition from which the tree suffers, or the threat it poses and providing a professional justification for the tree's removal. The city administrator shall then consider the arborist's letter and determine if a permit is warranted. If the city administrator does not approve the permit, then the applicant may appeal the decision to the city council.
(D) 
In all cases, the permit for removal must be received prior to removal of the tree except as otherwise provided for in subsection (c) below.
(c) 
Timing for no-fee permit.
The no-fee permit must be received prior to removal except when said trees or vegetation have naturally fallen onto a structure and/or are blocking a driveway, sidewalk or other means of egress from a property or structure. In such cases, the permit must be secured by the end of the next business day. Any tree stump(s) must be left in place until the city inspector has come on-site to measure the stump(s) for the purpose of determining the replacement requirements (if any).
(d) 
Exception.
(1) 
A permit is not required to remove trees or vegetation in the following instances:
(A) 
When the vegetation removal is considered common household gardening or ground care.
(B) 
When pruning live trees so that no more than 25% of a tree's live foliage shall be trimmed off or pruned per year. The Texas Forest Service at Texas A&M's best management practices recommends removing no more than 25% of the live foliage within the tree canopy in an annual growing season. Refer to article 24.04 regarding pruning times and methods for Oak Wilt prevention.

(iii) 
In all cases, no more than 25% of the tree's live foliage may be removed per year.
(2) 
Exemption from the requirement to obtain a permit does not exempt a person from adhering to the Code of Ordinances.
(e) 
Permit application process.
Each application for a tree removal permit shall be made by the owner of the property or by the owner's authorized agent. Applicants may contact the city by phone, U.S. mail, fax, e-mail or in person to request an appointment with the city inspector who will conduct an on-site meeting with the applicant in order to document the size, species, location and condition of the tree(s) to be removed. If granted by the city inspector in accordance with subsection (f) below, the applicant will receive a copy of the approved application to serve as the permit for display per subsection (g) below and the city shall retain a copy for its records.

(Ordinance 2021-005, att. B, adopted 6/23/21; Ordinance 2023-011 adopted 9/13/2023)
(a) 
Removal policy.
(1) 
Existing vegetation shall be left undisturbed to the maximum extent possible. In most circumstances, if a tree must be removed, it shall be replaced with a native, non-invasive species so that the native, natural landscape of the city is preserved for future generations.
(2) 
Trees less than ten (10) inches in diameter measured at a point fifty-four (54) inches above the ground may be removed with a permit in accordance with section 22.03.303(b).
(3) 
Trees greater than or equal to ten (10) inches and less than fourteen (14) inches in diameter measured at a point fifty-four (54) inches above the ground may be removed with a permit in accordance with section 22.03.303(b)(4). If a tree greater than or equal to ten (10) inches and less than fourteen (14) inches in diameter does not meet the requirements of section 22.03.303(b)(4) then the removal shall be requested through a variance as described by subsection (a)(4) of this section.
(4) 
The removal of trees greater than or equal to fourteen (14) inches in diameter measured at a point fifty-four (54) inches above the ground, or a tree greater or equal to ten (10) inches and less than fourteen (14) inches in diameter that does not meet the requirements of section 22.03.303(b)(4), is prohibited except as allowed under section 22.03.303(b)(7) and therefore such removal requires a variance from the city council as outlined in section 22.03.308.
(b) 
Removal procedure.
(1) 
Tree survey.
(A) 
For all new construction on an undeveloped lot without existing structures, the property owner must provide the city inspector with a tree survey of the entire property.
(B) 
For all new construction on a developed lot with existing structures, the city administrator at his sole discretion may allow the property owner to submit a tree survey of less than the entire property.
(C) 
All tree surveys must be conducted by a state-registered surveyor or engineer prior to a permit being issued and must include all trees with trunk diameters of three (3) inches or greater at twelve (12) inches above the ground.
(D) 
All trees to be removed must be highlighted or marked on the survey.
(2) 
Trunk diameters of the trees that the property owner proposes to remove shall be measured at a point fifty-four (54) inches above the ground. If a tree trunk splits at a height of less than fifty-four (54) inches, the tree diameter shall be calculated by adding the sum of the diameter of the largest stalk, plus one-half (1/2) of the diameter of all remaining smaller stalks all measured at a point fifty-four (54) inches above the ground.
(c) 
Violation of removal procedure.
(1) 
No person shall remove a tree in violation of this division.
(2) 
The diameter of trees removed in violation of this division shall be measured at the widest portion of the exposed base of the trunk for purposes of calculating replacement requirements. If no exposed base of trunk exists, then the city inspector shall estimate the diameter of trees that were removed for purposes of calculating replacement requirements.
(3) 
Any person removing tree(s) or vegetation in violation of the regulations provided in this division shall replace the tree(s) removed with tree(s) of equivalent species and size (caliper inches and canopy diameter). If tree(s) removed are not exhibit A tree(s), then exhibit A tree(s) must be used as replacements.
(4) 
Any person violating any of the provisions of this division shall be deemed guilty of a class C misdemeanor, and such offense shall be punishable by a fine not to exceed two thousand dollars ($2,000.00) per offense. Each tree removed in violation of this division shall be considered a separate offense. A person does not commit an offense under this section unless the person intentionally, knowingly, recklessly, or with criminal negligence engages in conduct as the definition of the offense requires.
(5) 
It is a separate offense to fail to replace trees or vegetation, or remit to the city cash-in-lieu, as provided in this code, within 601 days of issuance of a final order by the city.
(6) 
Criminal fines imposed under this code are in addition to replacement requirements and any other remedies available at law or in equity.
(d) 
Calculating tree replacement requirements.
(1) 
Trees of any species with a trunk diameter of less than six (6) inches do not require replacement.
(2) 
Conifer and Juniper trees (commonly referred to as “cedars”) with a trunk diameter of less than twelve (12) inches that are removed to establish a fire safety buffer zone in accordance with section 22.03.303(b)(5) do not require replacement.
(3) 
Conifer and Juniper trees (commonly referred to as “cedars”) with a trunk diameter of three (3l inches or less that are removed as a fire prevention measure in accordance with section 22.03.303(b)(6) do not require replacement.
(4) 
To compensate for the removal of live trees that are not diseased, dying or dead (as defined in accordance with section 22.03.303(b)(7)) and that are removed in accordance with this section, the property owner must install replacement trees according to the following requirements:
(A) 
All trees with trunk diameters equal to or greater than six inches and less than fourteen (14) inches must be replaced on a 75% basis. In such cases, the replacement trees planted must have trunk diameters of at least two (2) inches. For example, if a twelve (12) inch tree is removed, then a total of nine (9) replacement inches must be planted using trees with a minimum trunk diameter of two (2) inches.
(B) 
(i) 
All trees with trunk diameters greater than or equal to fourteen (14) inches require a variance to subsection (a)(4) above and must be replaced on a 150% basis. For example, if a sixteen (16) inch tree is removed, then a total of twenty-four (24) replacement inches must be planted using single-trunk trees with a minimum trunk diameter of at least two (2) inches.
(ii) 
Trunk diameter less than six (6) inches: No replacement required.
(iii) 
From six (6) inches to less than fourteen (14) inches: 75% replacement required: Must use replacement trees with trunk diameters of at least two (2) inches.
(iv) 
Fourteen (14) inches and larger: Requires variance; 150% replacement required: Must use replacement single-trunk trees with trunk diameters of at least two (2) inches.
(5) 
To compensate for the loss of diseased or dying trees, or a tree that poses an imminent threat to persons or property, removed in accordance with this section and with section 22.03.303(b)(7), the property owner must install replacement trees on a 50% basis. In such cases, the replacement trees planted must have trunk diameters of at least one and one half (1-1/2) inches. For example, if a nine (9) inch tree is removed, then a total of four and one half (4-1/2) replacement inches must be planted using trees with a minimum trunk diameter of one and one half (1-1/2 inches).
(6) 
In the case of dead trees removed in accordance with this section and with section 22.03.303(b)(7), no replacement is required.
(7) 
For purposes of calculating the replacement inches as required above, the trunk diameters of all replacement trees shall be measured at a point twelve (12) inches above the ground.
(8) 
Replacement trees shall count on an inch-for-inch basis.
(9) 
When using a species with multiple trunks (e.g., Texas Mountain-Laurel, Yaupon Holly, etc.) for replacement purposes, the following chart shall be used to convert the planting container measurement to the equivalent trunk diameter for the purposes of this section:
Planting Container Size
Equivalent Trunk Diameter
20 gallons
3 inches
30 gallons
4 inches
40 gallons
5 inches
(10) 
The planting of native grasses or ground cover is encouraged, but shall not satisfy any tree replacement requirement.
(e) 
Replacement procedure.
(1) 
The replacement trees shall be planted in appropriate locations with species listed in exhibit A only. When installing replacement trees, priority should be given to the setback areas and other locations in order to maximize the visible screening of buildings and structures on the property from adjacent properties. If an a1mropriate location cannot be located on the property in question, the city may allow the property owner to plant replacement inches on an alternate site owned by the city or the property owner based on the reforestation needs of the city if:
(A) 
Both the city and property owner agree on the location; and
(B) 
The location is within the city limits of the city.
(2) 
Whenever replacement is required, the property owner shall submit to the city inspector for approval a replacement site plan showing the locations, species and sizes of all replacement trees and vegetation prior to their installation. If during installation, the property owner is reasonably unable to conform to the approved replacement site plan, then the property owner must submit an amended site plan to the city inspector within seven (7) days of installation and ultimately subject to the city inspector’s approval.
(3) 
Installation of the replacement trees must be completed prior to the expiration of the tree removal permit and within ninety (90) days of receiving the approval of the replacement site plan from the city inspector. The city inspector may allow for additional time upon request due to weather or other circumstances beyond the property owner’s control.
(4) 
The property owner shall notify the city inspector upon completion of installation. The city inspector shall then verify that the installation conforms to the approved replacement site plan.
(5) 
All replacement and relocated trees must survive at least three (3) years. The city inspector may contact the property owner during this three (3) year period to arrange for a site visit by the city inspector in order to confirm that the trees have survived. Trees that do not survive for three (3) years must be replaced.
(f) 
Landscape fund.
(1) 
There is hereby created a landscape fund for the city.
(2) 
To qualify for the exceptions enumerated under this subsection (f), an applicant must provide a tree replacement site plan that accommodates at least 90% of the tree replacement inches otherwise required under this section. An applicant who has demonstrated the ability to replace this minimum threshold has qualified as “substantially complete.”
(3) 
When the city administrator determines that tree replacement requirements of this section cannot be reasonably satisfied on site, and the applicant has met the threshold of substantially complete, the remaining required replacement inches for trees greater than ten (10) inches (as measured at a point fifty-four (54) inches above the ground) may be satisfied by the payment in the amount as provided in appendix A to this code to the city and placed in the city’s landscape fund in lieu of planting additional required replacement trees. In making the discretionary determination, the city administrator shall consider the topography, existing and proposed structures, and condition of remaining vegetation.
(4) 
In the event the applicant’s replacement plan is not substantially complete (i.e., it cannot meet the 90% threshold set forth above), the city council will have the sole authority to determine what, if any, monetary funds may be accepted in lieu of tree replacement. The city council reserves the right to require the applicant to comply with all tree replacement requirements under this section.
(5) 
Proceeds accumulated in the landscape fund shall be expended solely on tree preservation or landscaping projects on public property throughout the city.
(Ordinance 363 adopted 4/11/18)
(a) 
Tree pruning must not be done in a manner that is detrimental to the tree. Any action undertaken which intentionally or recklessly causes or tends to cause injury, death, or disfigurement to a tree is considered to be detrimental. Examples of detrimental actions which are prohibited may include cutting, poisoning, burning, over-watering, relocating, or transplanting a tree.
(b) 
Tree protection that meets City of Austin standards must be provided during any construction project. City of Austin standards can be found online at http://www.ci.austin.tx.us/trees/preserve_code.htm.
(c) 
Compliance with all oak wilt regulations found within this code is required, including, but not limited to, the immediate application of an appropriate pruning sealant on all fresh cuts. For more information about oak wilt diagnosis, treatment and prevention, please visit the Texas Forest Service’s website at http://www.texasoakwilt.org/.
