Answering your questions about Article X, of the Dallas Development Code,
The Landscape and Tree Preservation Ordinance

Article Ten was passed in May of 1994. It revised the existing Landscape Code and added provisions for preserving trees. It required a permit for removing protected trees within city limits of Dallas, and outlined guidelines for protecting trees during construction. Trees on lots less than two acres and in current single family or duplex use are exempt from the tree preservation code. Trees on the parkway are not exempt and require a permit for removal.
The Dallas city staff responsible for enforcing Article X are the Arborists, a team of degreed professionals with backgrounds in forestry, biology, and environmental sciences. You can meet your City Arborists by clicking on the link below.
These pages were designed by the City Arborists to help guide you through the requirements of the Landscape and Tree Preservation Ordinance. They are however, still available to answer your questions by phone or by appointment in room 105 at the Oak Cliff Municipal Center at 320 E. Jefferson. Follow the Meet Your Arborist link to determine which arborist covers your area and obtain their phone number.
