Corner sight triangles on county roads follow TxDOT and Travis County Transportation & Natural Resources standards during subdivision platting. No post-construction fence height enforcement exists unless a sight obstruction creates a safety hazard on a county-maintained road.
Travis County Transportation & Natural Resources (TNR) enforces sight-distance standards at the subdivision plat stage under the Travis County Subdivision Regulations and TxDOT Roadway Design Manual. Typical sight triangles measure 25 feet along each leg at local-road intersections and 30–55 feet on collector/arterial corners, with maximum obstruction height of 3 feet (or 36 inches) above pavement grade. Because the county cannot zone, TNR lacks proactive enforcement power over fences installed after platting. Complaints about obstructed corners on county-maintained roads (indicated by '1000-series' Travis County Road signs) are investigated by TNR Road Maintenance, which can require removal under TX Transportation Code §251.016 (removal of obstructions in the right-of-way). Private HOA streets enforce sight triangles through covenants. Contact TNR: (512) 854-7520.
TNR right-of-way obstruction: removal order under TX Transportation Code §251.016; continued obstruction can lead to county crew removal at owner expense and civil penalties up to $500 per occurrence.
