Houston FAQ
Can I plant a live oak in front of my Harris County house in the parkway?
Possibly, with a free Harris County Engineering ROW permit confirming species, sight distance, and utility clearance. Live oak is on the H-GAC approved list but mature canopy spread often conflicts with overhead lines, so silver-tier species may be required.
Who maintains parkway trees in Harris County?
Adjacent property owners maintain parkway trees including pruning, watering, and removal of dead limbs. Harris County only intervenes if the tree obstructs sight, blocks drainage, or fails. Houston ROW trees are similarly maintained by abutting owners.
