Heritage trees are similar to protected trees, but are generally subject to much stricter rules. Heritage trees must measure more than 24 inches in diameter. Protected trees and heritage trees are subject to specific removal and development-related impact regulations. Heritage trees can only be removed after a variation is approved.
They can be removed without any variation only under the same circumstances in which a protected tree can be removed without permission (see above). The town's arborist will come to inspect the conditions. It's rare to get a variation to remove a heritage tree for any reason other than the above. While technically all protected trees are created the same way, in my experience some trees (such as oak trees) are more protected than others.
If for some reason a tree that is 8 inches in diameter or larger must be removed (at least in the city of Austin), there are a few things you can do depending on the type of tree listed above. The only exception is if the tree is damaged and removed within 7 days of the damage, and the tree causes an “imminent danger to life or property”. Protected tree removal: While it is easier to remove than a heritage tree, a protected tree must still be requested to be removed. You can remove a tree in the city of Houston without a city permit, as long as it is not a protected tree.
In certain situations where tree felling is authorized, the city will require mitigation measures, often by planting replacement trees. Mitigated tree removal: If you want to remove a tree of 8 or more, other than a protected or heritage tree, all you have to do is mark its removal on the site plan. If you're thinking about building in Austin, you've probably heard of protected trees and Austin tree ordinances. Personally, I love lots with trees because I think they give new homes more character, so I've become familiar with the city's tree rules.
Heritage trees larger than 24 inches, but smaller than 30 inches, require an administrative variation from the director of the Department of Developmental Services before removal. When a protected tree is not developmentally related but is affected by utility problems, diseases, or other conditions, a request for revision of the tree ordinance is required. If a protected tree is dead or poses a hazard to people or property, you can remove a protected tree without a permit. When trees have multiple stems, if the diameter of the largest stem plus half of all other stems is two feet or more, it is also considered a heritage tree.
The workshop will also provide guidance on how to apply for a tree permit and will provide useful tips on tree care. It's important to have a good understanding of the city's tree rules to determine what can be built on lots with large trees.
