Summary
Buckeye's Development Code caps retaining wall height at 12 feet and requires walls over six feet along a public right-of-way to be terraced in stages no taller than six feet each.
The height of retaining walls supporting either cut or fill conditions shall not exceed 12 feet in height measured vertically from the lowest point at natural grade to the highest point of the wall. Retaining walls greater than six feet in height that are visible from public ROW shall be terraced to minimize visual impacts on residents and neighboring properties by limiting terracing to three tiers, with each tier no greater than six feet in height.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 22 Update 1).
Full Breakdown
The city's Development Code treats retaining walls as part of its fences-and-walls screening standards: any wall holding back cut or fill soil is capped at 12 feet, measured from natural grade to the wall's highest point. Once a retaining wall exceeds six feet and is visible from a public right-of-way, the code requires it to step back in terraces, no more than three tiers, each capped at six feet, with landscaped setbacks between tiers, rather than rising as one tall face. In officially mapped Hillside Areas (natural slope of 15 percent or greater), a separate Development Code section additionally requires retaining wall and erosion-control designs to be prepared and stamped by an Arizona-licensed engineer or architect.
Violations & Fines
Building a retaining wall over 12 feet, or skipping required terracing on a visible wall over six feet, is a Development Code violation subject to code enforcement and site-plan/permit denial.
