What is a Protected Tree in Austin?
Defining Preservation Regulations
In Austin, the term 'protected tree' refers to specific trees classified under the Land Development Code (LDC) to promote urban forestry and sustain the city's green infrastructure. These trees, vital to the city's environmental health, are identified by their size, with a diameter at breast height (DBH) of 19 inches or more, measured at 4.5 feet from the ground. This measurement equates to a circumference of 60 inches. Trees meeting these criteria offer substantial ecological benefits, including air purification, aesthetic enhancement, and the natural cooling of urban areas.
The City of Austin has established regulations to conserve these mature trees, and as such, it mandates that a permit is required to remove or otherwise impact a protected tree. This measure seeks to ensure that the city's tree canopy is not reduced without careful consideration and only when it is deemed necessary. The city's arborist program oversees the approval of such permits and enforces the preservation of these trees both on private and public properties.
Protected trees often embody a heritage quality, signifying not only their ecological importance but also their role in defining the character of neighborhoods and streetscapes across Austin. By enforcing these measures, the city aims to maintain a balanced and healthy environment for its residents, preserving the charming and leafy avenues that contribute to Austin's unique urban landscape. These efforts highlight the city's commitment to sustainable development and ecological stewardship.
Understanding Protected Trees
In Austin, the protection of trees is a serious matter, reflecting the city's dedication to preserving its natural beauty and ensuring environmental sustainability.
Definition of Protected Trees
Protected trees in Austin are designated by specific criteria, primarily focused on the tree's size and species. Protected trees refer to those with significant value due to their age, size, and type, which are essential to the urban forest ecosystem.
Tree Size and Protected Status
The status of a tree as protected is primarily determined by its diameter at breast height (DBH), which is the tree's diameter measured at 4.5 feet above the ground. In Austin:
Trees with a DBH of 19 inches or more are classified as protected.
A permit is required for the removal of these trees.
The list of tree species that fall under the protection regulations includes, but is not limited to:
Oaks (Quercus spp.)
Cedar Elm (Ulmus crassifolia)
Bald Cypress (Taxodium distichum)
Walnut (Juglans spp.)
Pecan (Carya illinoinensis)
Eastern Black Walnut (Juglans nigra)
American Elm (Ulmus americana)
Texas Ash (Fraxinus texensis)
Bigtooth Maple (Acer grandidentatum)
Texas Madrone (Arbutus xalapensis)
The city's guidelines ensure that these important tree species are preserved for the ecological and aesthetic benefits they provide to the community.
Regulatory Framework
Austin's approach to tree protection is grounded in a series of robust regulations aimed at maintaining the city's urban forest. These ordinances are in place to safeguard trees, which are an essential part of the environmental infrastructure and landscape.
City of Austin Tree Ordinance
Under the City of Austin Tree Ordinance, trees are managed based on their size and species. This ordinance requires permits for the removal or impact of regulated trees. On private properties, the city regulates trees with diameters ranging from 8 to 18 inches, Protected Trees, and Heritage Trees. The goal is to balance urban development with the preservation of Austin's canopy cover.
Protected trees: Generally, these are trees with a diameter at breast height (DBH) of 19 inches or more.
Permits: Mandatory for tree removal or work impacting a regulated tree.
Heritage Tree Ordinance
The Heritage Tree Ordinance specifically protects a subset of trees deemed Heritage Trees due to their size, species, and age. These are considered irreplaceable due to their ecological and aesthetic value.
Definition: Heritage trees are usually large, prominent trees that meet criteria set by the city for size and species.
Restrictions: Stringent guidelines and greater protection from removal or impact.
Environmental Criteria Manual
The Environmental Criteria Manual is part of the Land Development Code (LDC) and is used as a reference for environmental policies, including tree protection guidelines. It supplements the Tree Ordinance and provides detailed criteria for the protection, maintenance, and enhancement of Austin's urban forest.
Guidelines: Offers specific standards for tree protection during construction and development.
LDC Integration: Interprets the Land Development Code's tree-related policies for practical, consistent application.
These framework components ensure that the City of Austin maintains a healthy urban forest while accommodating for growth and development, underscoring the city's dedication to environmental stewardship.
Permitting Process
In Austin, the management of tree permits is a structured affair, governed by specific regulations to protect significant trees. This process ensures that tree removal or impact complies with the city's standards to maintain its urban forest.
Permit Requirements
Tree permits are mandatory when a person intends to remove or impact regulated trees on private property. Protected Trees, those with a diameter at breast height (DBH) of 19 inches or more, particularly necessitate a permit before any alteration. The City Arborist Program oversees the permit issuance through the Development Services Department. Variations arise based on the type of tree and its location.
Protected Trees: Permits required for removal or impact.
Heritage Trees: Special considerations and more stringent requirements.
Private Property Trees (8- to 18-inch DBH): May need permits, depending on the circumstances.
The criteria for permit issuance hinge on the rationale for removal, the tree's condition, and the potential for replacement.
Tree Ordinance Review Application (TORA)
The Tree Ordinance Review Application (TORA) is a prerequisite for the permitting procedure. Applicants must submit the TORA for projects that involve:
Removing a tree.
Pruning more than 25% of the tree's canopy.
Engaging in activities that may impact the tree or its critical root zone.
Austin Build + Connect, an online platform, facilitates the electronic submission of TORA. It's integrated within the broader Development Services Department's system to streamline the process.
Consultation with City Arborist
Consultation with a City Arborist is often necessary as part of the permitting process. They review applications and guide property owners and developers through compliance with the tree ordinance. They possess the authority to grant or deny tree permits based on the evaluation of a tree's condition, size, species, and impact on the surrounding environment.
A City Arborist may also provide expertise on best practices for tree preservation during construction and development. There are situations where a residential plan review or additional consultations are required, particularly for more complex cases involving Heritage Trees or significant tree-related activities.
Contacting the City Arborist can be done via the Development Services Department or through tools like the Tree Manager on the city’s website, ensuring an informed permitting process.
Preservation and Removal
In Austin, tree preservation is taken seriously, and the removal of protected trees is closely regulated to maintain the city's urban forest. Specific criteria must be met for lawful removal, mitigative measures are required to minimize impacts, and penalties are in place for unauthorized tree removal.
Criteria for Tree Removal
Protected trees can only be removed under certain conditions and typically require a permit issued by the City Arborist. Tree removal is permitted if the tree is:
Dead or diseased: Trees that are no longer viable and pose a risk to property or public safety.
Imminent hazard: Trees that may cause immediate harm during severe weather conditions or because of structural instability.
DDI Trees: Trees designated as dead, diseased, or an imminent hazard.
The critical root zone (CRZ) must be considered during any removal process to prevent unnecessary damage to the tree's support system.
Mitigating Impact on Trees
Preservation Measures: Developers and property owners must ensure protective barriers around trees' critical root zone during construction activities.
Pruning Practices: Pruning should adhere to the City's standards, avoiding excessive cutting that may harm the tree's health.
If removal is unavoidable, replacing the removed tree or contributing to the city's tree fund may be required as compensatory measures.
Penalties for Unauthorized Removal
Unauthorized removal or impact on protected trees can lead to significant fines. The City of Austin may impose:
Fines: Monetary penalties for each inch of tree diameter removed or impacted without a permit.
Replacement: The requirement to plant new trees to mitigate the unauthorized removal.
Enforcement of these regulations ensures the city's tree canopy is protected for future generations.
Protection Measures
In Austin, trees with significant size and species are safeguarded through meticulous regulation to maintain the urban forest's integrity. The city's measures focus on maintaining the health and safety of trees during both everyday and construction activities.
Critical Root Zone Protection
The Critical Root Zone (CRZ) is a fundamental element of tree protection. In Austin, the CRZ is defined as a protective area surrounding a tree, extending out from the trunk as one foot for every inch of the tree's diameter. Activities within the CRZ, such as soil compaction, excavation, or placement of materials, may need a permit and must comply with city regulations. Failure to adhere to these standards can be grounds for variances and penalties.
Construction Impact Reduction
To reduce negative impacts on protected trees during construction, Austin enforces guidelines and permit requirements. Contractors must employ protective measures such as fencing to shield trees and their CRZs. The Community Tree Preservation Division plays a role in overseeing construction activities in the vicinity of protected trees to ensure adherence to tree protection standards. The division may also mandate specific construction methods to minimize damage to the urban canopy.
Public Education on Tree Care
Austin actively engages in a public process to educate the community about proper tree care and preservation. The city provides resources and guidelines to ensure residents understand their role in maintaining the urban forest. The Community Tree Preservation Division offers support and information to the community, fostering a collaborative effort in urban forest management. This partnership between the city and its residents is critical for the sustained health of Austin's treasured trees.
