(Section 40.03.212 Vision Clearance, Lubbock Code of Ordinances)
There are three areas in which view obstructions are not allowed. The first area is in the parkway, or that area between the street and sidewalk, (or if there is no sidewalk, where the sidewalk would normally be placed). No plant material, sign or structure higher than three (3) feet may be placed there, with the exception of deciduous (lose leaves in fall) trees, which must be kept trimmed so that no foliage is present less than six (6) feet in height from the curb.
The second area in which view obstructions are not allowed is a corner lot. No plant, sign, or structure higher than two (2) feet may be placed within the ‘visibility triangle’. The ‘visibility triangle’ is a triangle measured from the curb at the corner, and twenty-five feet back along each intersecting street (see illustration below).
Finally, the third area of vision clearance importance is the front yard. No wall, fence, or other structure is permitted that would be higher than two and one-half (2 ½) feet at the front lot line and four and one-half (4 ½) feet at the depth of the required front yard (see illustration, next page).
In addition, no plant material is allowed to interfere with the free passage of vehicles along the street, or of pedestrians on the sidewalk. Plant material must not block the view of street signs or interfere with traffic. CORNER
No trees may be planted in the visibility triangle. Maximum height for any fence or other object in this area is two (2) feet.
Trees in the parkway or overhanging the parking area must be trimmed so that no foliage is less than 6 feet from the ground. No evergreen or coniferous trees are allowed. Maximum height for other plants is three (3) feet.
1. Front Yards. In a required front yard, no wall, fence or other structures shall be erected in any part of the required front yard that would be higher than a line extending from a point two and a half (2 ½) feet above the natural ground level at the front lot line to a point four and a half (4 ½) feet above the natural ground level at the depth of the required front yard.
2. Corner Lots. It shall be unlawful to set out, construct, maintain, or permit or cause to be set out, construct, or maintain any tree, shrub, plant, sign or structure, or any other view obstruction having a height greater than two (2) feet as measured from the top of the curb of the adjacent streets within the intersection visibility triangle. This restriction shall not apply to traffic control signs and signals, street signs, or utility poles placed within such area by authority of the City Council. Intersection visibility triangle shall mean a triangle sight area, at all intersections, which shall include that portion of public right-of-way and any corner lot within a triangle formed by a diagonal line extending through points on the two (2) property lines twenty-five (25) feet from the street corner intersection of the property lines (or that point of intersection of the property lines extended) and intersecting the curb lines.
3. Parkways. It shall be unlawful to set out, construct, maintain, or permit to be maintained, set out or construct any shrub or plant (excluding trees), sign or structure, or any other view obstruction having a height of greater than three (3) feet, as measured from the top of the curb of the adjacent street in the parkway area. All trees with a trunk diameter greater than two (2) inches measured three (3) feet above ground level that are within any of the parkway area shall be trimmed so that no foliage is less than six (6) feet above the top of the curb of the adjacent street. No evergreen or coniferous species of tree shall be allowed in the parkway.
This section shall not apply to traffic control signs and signals, street signs, mailboxes that are less than two (2) feet long on each side, which is perpendicular to the street, or utility poles placed within the parkway. No such tree, shrub, plant, sign or structure (including mailboxes) shall be allowed to interfere with the free passage of vehicles on the street or of pedestrians on the sidewalk or to obscure the view of motor vehicles operators of any traffic control device or street sign or otherwise create a traffic hazard.
4. Enforcement. It shall be the duty of the zoning and environmental control administrator to cause written notice to be served upon the owner or occupant of any property upon which any of the above violation exist or upon any owner or occupant of any property which abuts any parkway area upon which any of the above violations exist to correct such violation within ten (10) days after service of such notice. If such violation in a parkway area either within or without the visibility triangle is not corrected within the ten day period, the zoning and environmental control structure constituting such violation in the parkway are to be trimmed, pruned or removed to eliminate such prohibit condition, with the cost of such trimming, pruning or removal to be assessed against the abutting property owner. This authority shall be in addition to any other remedy provided by law.
