Willows — Landscaping and Screening

Last reviewed: July 6, 2026

Overview

This page distills what the City of Willows Zoning Ordinance (WMC Title 18) requires for landscaping, screening, fences, and related site features. In Willows, most project-specific landscape and screening outcomes are set through design review, with some zone- or overlay-specific rules layered on top. If you are working on commercial, multifamily, industrial, or overlay parcels, plan early for submittable landscape drawings, long-term maintenance, and targeted screening of views of service areas and equipment.

Key rule in plain English: If your project triggers design review, you must submit a landscape plan, screen parking/loading/refuse/mechanical equipment from public view, maintain planting in good condition (replace dead/dying plants), and complete landscaping before the City issues occupancy. See § 18.141.050(4)(g)–(h), § 18.141.060(5), (11), and § 18.141.090(2) .

How Willows regulates landscaping and screening

• Citywide applicability: Title 18 applies throughout incorporated Willows and all development must conform to it . See the Willows Zoning map/district framework.
• Design Review is the backbone: Landscaping is a review item, with required content (tree inventory thresholds; landscape/irrigation/lighting coordination) and approval criteria about screening and ongoing maintenance .
• Overlays can add rules: The F Frontage Combining District requires screen planting or fencing for open-land commercial use permits, and the PD Planned Development overlay requires preliminary landscape plans and a maintenance program as part of approval .
• Some base districts set explicit landscape percentages or screening: The R‑P district requires a minimum landscaped open space percentage, and the MH district mandates solid fencing for certain outdoor yard uses .
• Fences in residential districts have height caps that often shape front yard landscape/screening strategies, and certain corridor districts control where parking may sit, further pushing landscaping to frontages; see below and Willows Parking for frontage/yard effects .

Submittal and performance standards that affect every landscaped site

• What you must submit at design review:
  • Existing tree/large shrub/hedge inventory with specific size thresholds; removals must be identified (§ 18.141.050(4)(g)) .
  • A landscape plan showing all planted areas, irrigation components, and plant sizes and spacing (§ 18.141.050(4)(h)) .
  • An exterior lighting plan coordinated with the landscape/irrigation layout (§ 18.141.050(4)(i); § 18.141.060(10)) .
• What the City looks for:
  • Walls, fences, or screening to hide parking/loading, refuse areas, and mechanical equipment from public and on-site views (§ 18.141.060(5)) .
  • Well-designed landscaping with appropriate plant selection, used “where needed” for screening; irrigation may be required; and all planting must be maintained with dead/dying plants replaced (§ 18.141.060(11)) .
• Enforcement trigger: Landscaping must be installed before occupancy or bonded for completion (§ 18.141.090(2)) .
• Integration with other topics: Signs and lighting must be integrated into the site design; see Willows Signage and Willows Development Standards for related parameters (§ 18.141.060(9)–(10)) .

Quick-reference standards and triggers

District-by-district notes on landscaping and screening

Willows’ base and combining districts are established in § 18.10.010–.020; use this as a guide to which standards apply and when overlay rules stack on top of base zone rules .

R-1 Single-Family Residential

• Purpose/uses/dimension highlights: Not found in retrieved materials.
• Landscaping/screening specifics: Design review generally exempts single-family on individual lots (§ 18.141.040(1)), so formal landscape plan submittals typically do not apply to a one-off SFD; residential fences capped at 3.5 ft in the front 25 ft and 6 ft in side/rear (§ 18.110.050(2)) .
• Where it applies: Citywide R-1 mapped areas.

R-2 Two-Family Residential

• Purpose/uses/dimension highlights: Not found in retrieved materials.
• Landscaping/screening specifics: Same fence height controls as R districts; duplexes on individual lots are generally exempt from design review (§ 18.141.040(1)), but multifamily-type projects or tract-built homes can trigger review with landscape plans and screening (§ 18.141.030(2)(a)–(b), § 18.141.050) .
• Where it applies: Citywide R-2 mapped areas.

R-3 High-Density Residential

• Purpose/uses/dimension highlights: Not found in retrieved materials.

CC Central Commercial

• Purpose: Pedestrian-oriented downtown retail/service districts (§ 18.55.010) .

Overlay Districts that change landscaping/screening

F Frontage Combining District

• What it does: Adds corridor standards on top of the base zone; requires “screen planting or fencing” for permitted commercial uses on open land as a condition of a use permit (§ 18.100.030(2)) .
• Practical tip: Be ready with a frontage landscape/screening concept if your commercial use is primarily open-yard.

PD Planned Development Combining District

• What it does: Requires preliminary/final landscape plan submittals and a written maintenance/operations program for landscaping and open areas (§ 18.105.030(2)(h), (j)) .
• Practical tip: In residential PDs, open space minimums apply (40% outdoor open space overall; not all landscaped), separate from but complementary to landscape plan requirements (§ 18.105.050(4)) .

Related requirements that shape landscaping

• Parking location/design: The Entryway District bans front-of-building parking; other districts rely on design review to ensure parking areas are screened and pedestrian-friendly (§ 18.50.050(f); § 18.141.060(5), (7)) .
• Signs and frontage improvements: Integrate plantings with sign placement and lighting; sign location/lighting limits and sight visibility apply. See Willows Signage (§ 18.141.060(9); § 18.125.110(1), (7)) .
• Fences as structures: Yard fence heights are zoning matters; structural aspects fall under the California Building Standards Code generally, but that is outside this page’s scope (§ 18.110.050) .

Checklist

• Confirm your zoning and any overlays on the parcel via Willows Zoning; check for F or PD overlays (§ 18.10.010–.020) .
• Determine if your project is subject to design review; if yes, prepare required landscape, tree, and lighting plans (§ 18.141.030; § 18.141.050(4)(g)–(i)) .
• For R‑P sites, allocate at least 30% of the lot to landscaped open space (§ 18.45.040(4)) .
• For E district sites, keep parking out of front yard zones and design landscaped frontages (§ 18.50.050(f)) .
• For F overlay commercial open-land uses, provide screen planting or fencing per your use permit (§ 18.100.030(2)) .
• For MH yards (e.g., contractor/junkyards), enclose with a solid fence or wall at least 6 ft high (§ 18.75.020(6)) .
• Screen parking, loading, refuse, and mechanical equipment with walls/fences/landscaping; plan for maintenance and replacement (§ 18.141.060(5), (11)) .
• Complete landscaping before occupancy or post a bond acceptable to the City (§ 18.141.090(2)) .

Risks & Ambiguities

Plain-English Summary

In Willows, most landscaping and screening outcomes come through design review: you submit a tree/landscape/lighting package, the City requires screening for parking/loading/trash/mechanical areas, and you must install and maintain planting. Specific zones add rules: R‑P needs 30% landscaped open space; the E corridor bans front parking (so expect landscape-fronted buildings); the F overlay may require screen planting or fencing; and MH requires solid walls for certain yards. If a rule isn’t in the base district, assume design review will set the standard.
