Casa Grande, AZ Tree Protection: Parkway Planting (2026)

Casa Grande requires street frontage landscaping on applicable development projects under Municipal Code § 17.52.510(A): at least one tree and three shrubs for every thirty feet of street frontage, plus vegetative groundcover across a minimum of sixty percent of the frontage landscape area. That planting can sit either in the street right-of-way landscape strip required by § 17.52.490 or within the front twenty-five feet of the on-site landscaped area required by § 17.52.480, and it must be arranged to enhance the streetscape rather than simply meet a minimum count.

Where a development instead backs or sides onto a street behind a six-foot screening wall, § 17.52.550 substitutes a different planting requirement in place of § 17.52.510: three shrubs and one tree for every thirty feet of that street frontage, watered by an automatic drip or bubbler system, with quarter-inch-minus decomposed granite groundcover installed without plastic liners. Section 17.52.560 requires that quantities required under §§ 17.52.510 through 17.52.550 be added together across a single project to reach the total plant count Planning and Development checks against the approved landscape plan. Frontage plantings near driveway exits, alleys, and intersections must also clear the sight-visibility standards of § 17.52.160(C).
