Garden Grove — Landscaping and Screening

Last reviewed: July 2, 2026

Overview

This page summarizes what the Garden Grove Zoning Code requires specifically about landscaping and screening (trees, berms, planters, fences/walls, trash/storage screens) for projects in the city. It interprets the code language (Title 9 zoning chapters) into practical rules applicants will encounter and points to the controlling code sections so you can verify details. For related topics see the city's pages on parking, development standards, design review, overlay districts, ADUs and the California Building Standards Code.

Key citywide rules (short list)

• Required landscape materials and water-efficiency rules apply to most discretionary projects and a subset of large ministerial projects; landscape and irrigation plans are required where the landscape water efficiency rules apply. See § 9.18.120.010 and § 9.18.120.020.
• Screening of undesirable elements (trash, utilities, storage yards, freeway-facing areas) must be done with plantings (evergreen shrubs/trees), berms, or walls; berming cannot exceed 36 inches above adjacent curb at arterial entries. See § 9.12.040.050 O (screening rules referenced across zones).
• All landscaping next to parking/vehicular areas must be separated with a raised continuous six‑inch concrete curb. See § 9.12.040.050 P.
• Perimeter/masonry block walls are commonly required for new developments with a minimum six‑foot height measured from the highest adjacent grade; new walls generally must not exceed seven feet as measured from the finished point-of-grade (and may not exceed eight feet measured from adjacent neighbor grade unless a specific exception applies). See § 9.12.040.140 U and related wall provisions § 9.16.040.110 and § 9.18.130.010.
• Parking-lot landscaping and tree standards: shade trees are required in parking areas (example: one tree per four parking spaces for visible lots; minimum 24-inch box at planting); planters must meet minimum widths. See parking/landscape design rules in § 9.18.140 (parking & landscaping standards).

District-by-district breakdown

Note: each district subsection names the official Garden Grove zone identifiers and points to the local code section(s) that regulate landscaping/screening for that district.

• Typical uses: integrated commercial + residential; pedestrian-oriented frontages.
• Key landscaping/screening standards:
  • Special Garden Grove Boulevard tree requirements: when a property abuts Garden Grove Boulevard, columnar trees (minimum 24‑inch box at planting, spaced no more than 40 feet on center) are required within 10 feet of the Boulevard property line for GGMU‑1 (and pedestrian/plaza areas required within front setbacks). See § 9.18.100.030 (Garden Grove Boulevard Tree Requirements).

Decision‑relevant standards (quick table)

Information Gaps (what the ordinance files uploaded did not make explicit)

• The exact planting species matrix and the City "Guidelines" (Appendix 1, Title 9) with the hydrozones and plant water‑use factors were referenced but the full Appendix 1 content was not available in the retrieved materials. Verify required species/lists with the Planning Division. Not found in retrieved materials.
• Administrative checklists, plan submittal templates and fees for landscape/irrigation plan review are not in the uploaded zoning excerpts. Verify timing, plan format and fees with the Planning counter. Not found in retrieved materials.
• Some text about substitute landscaping and artificial turf appears in multiple subsections but the code location header for those detailed lists was not always explicit in the excerpts; where you rely on artificial‑turf allowances, verify the controlling subsection in the full code. See the "Substitute Landscaping" paragraphs in the retrieved excerpts and confirm with staff.

Checklist

• Prepare a site plan showing all setback areas, proposed plantings, planter dimensions, and irrigation components. Required where landscape water‑efficiency provisions apply. See § 9.18.120.010 / § 9.18.120.020.
• Show separation between planting areas and parking/drive aisles via a continuous 6‑inch raised curb (or approved alternative); label curb details. See § 9.12.040.P.
• If project includes trash enclosures, utilities, storage yards or truck parking, show screening with evergreen shrubs/trees or walls and list wall heights (industrial: 6–7 ft, truck screening 7 ft). See § 9.12.040.O and § 9.16.040.040.
• If proposing perimeter masonry walls, dimension heights from the highest adjacent finished grade and make sure front‑setback walls do not exceed 36 in. Show decorative treatment for street‑facing walls. See § 9.12.040.U.
• For parking lots, include tree counts and planter dimensions (example standard: 1 tree / 4 stalls, 24‑inch box min; planter min widths). See § 9.18.140.
• For projects abutting Garden Grove Boulevard in GGMU zones, show columnar trees within 10 ft of the property line, planting sizes and spacing per § 9.18.100.030 (Garden Grove Boulevard Tree Requirements).

Risks & Ambiguities

Plain‑English summary

Garden Grove’s zoning code requires most projects to provide meaningful landscaping and screening: plant trees and shrubs to block views of trash, storage, utilities and parking; separate planting from driving areas with a raised 6‑inch curb; and provide masonry perimeter walls for many new developments (typically 6–7 ft, with front yard walls limited to 36 in.). Where projects are large or discretionary you must submit a landscape and irrigation plan showing plant species, planters, irrigation and how water‑efficiency standards are met; look up § 9.18.120 and the perimeter wall rules in § 9.12.040.U to start.
