Corpus Christi, TX Tree Protection: Parkway Planting (2026)

13 of the Unified Development Code, any project that triggers a Streetscape Zone, generally new development fronting an Arterial or Collector Street, must incorporate street trees along the entire building line, except along alleys, whenever the existing or planned sidewalk measures at least 10 feet wide. 1 requires the trees to be drought tolerant or semi-tolerant species, planted in the Street Furniture/Landscaping Zone at a maximum of 40 feet on-center, and kept outside the 5-foot pedestrian Clear Zone that must stay unobstructed. 2 sets the planting pit standard: a tree well with at least a 5-foot radius extending from the inside edge of the curb, forming a semi-circle or a 5-foot by 5-foot square well, and the tree itself must be a minimum 15-gallon container size, which the code states is preferred over boxed specimens because boxed trees tend to be root bound.

3 substitutes raised bed or isolated planters with drought-tolerant flowering plants or evergreens at a tighter maximum of 15 feet on-center, and allows small ornamental trees, low shrubs, and perennials as planting material. 4 also allows a street wall/planter to satisfy the street tree requirement while doubling as seating. 5 directs that planting locations account for overhead and underground utilities, sightlines to traffic signals, signs, and intersections, and the risk of damage from car doors where trees sit near parallel parking. 6 folds in the citywide Landscaping Ordinance standards for commercial plant materials on top of these placement rules. 1, including any Use Privilege Agreement needed for plantings, furniture, or other installations placed in the zone.
