Lewisville, TX Landscaping Rules: Tree Removal & Heritage Trees (2026)

Lewisville Code of Ordinances includes tree preservation provisions that apply primarily during development and site plan review. Protected trees are generally defined as those with a trunk diameter of six inches or greater measured at 4.5 feet above grade (diameter at breast height). During site development, a tree survey and preservation plan may be required showing which trees will be retained and which removed. Removal of protected trees typically requires mitigation through replacement plantings or payment into a tree fund at a ratio established by the ordinance. On existing developed residential lots, property owners generally may remove trees on their own property but are encouraged to replace removed shade trees. Dead, diseased, or hazardous trees may be removed without mitigation requirements. Trees in the public right-of-way are city property and may not be removed without city authorization. The city forester or designated official reviews tree removal requests for development projects. Texas Property Code Sec. 202.007 limits HOA authority to prohibit certain drought-resistant landscaping but does not restrict city tree ordinances.
