Corner lots in McKinney must maintain a visibility triangle at intersections where fences, walls, and landscaping cannot exceed 3 feet in height within 25 feet of curbs per Engineering Design Standards.
McKinney's Engineering Design Manual and UDC Sight Visibility Triangle provisions require corner lots to keep an unobstructed triangular area at the intersection of two streets, or at a street and a driveway/alley. The triangle is measured 25 feet along each curb line from the point of intersection, producing a 25-by-25-foot sight area. Within that triangle, nothing between 3 feet and 8 feet in height is permitted: no solid fences, no masonry walls, no hedges, no landscape mounding, no mailbox enclosures, and no parked vehicles. Tree canopies must be limbed up to 8 feet so drivers can see through the trunk zone. The rule applies to all McKinney intersections, including low-traffic residential corners in neighborhoods like Eldorado Heights and high-volume arterials at Custer/Virginia Parkway. Driveways entering arterial streets (SH-121 frontage, US-75 access roads) may require a larger triangle per TxDOT standards. Violations are treated as strict-liability site-distance hazards; Code Compliance can demand immediate trimming or removal, and the city may enter the right-of-way to cut vegetation at the owner's expense if a notice is ignored. This rule is enforced jointly by Engineering, Code Compliance, and Police traffic units after collisions.
Correction notice with 10-day cure period. Uncured violations cited at $200-$2,000. City may trim/remove at owner expense and lien the property for costs.
