Fountain Valley — Landscaping and Screening

Q: Do MU (mixed‑use) projects follow the same landscaping rules?

Yes — MU zones reference Chapter 21.20 for landscaping generally, but MU standards (Table 2‑11) may adjust how certain perimeter or interior open spaces are counted. Always reconcile Table 2‑11 with Chapter 21.20 when calculating compliance. § 21.20.040 and Table 2‑11.

Overview

This page summarizes what the Fountain Valley Development Code (Title 21) requires for landscaping and screening (including fences, walls, buffers, parking-lot landscaping, and screening of equipment or storage). It interprets the code language you will use in project plans and permit applications and points to the exact local code sections to verify details. For related topics see the city's Fountain Valley Zoning and the Fountain Valley Development Standards.

Key controlling provisions are: § 21.18.070 (fences/walls), § 21.18.080 (screening & buffering), and Chapter 21.20 (landscaping) — see the specific citations below for each rule cited.

How Fountain Valley’s rules are organized (short)

General lot and yard rules that affect landscaping and fences live in the development-standards chapters and general standards (e.g., § 21.18.040 corner cutback; § 21.18.070 fences/walls).
Specific landscape quantity/plan standards are in Chapter 21.20 (e.g., § 21.20.040 minimum landscape area; § 21.20.050 landscape plan requirements).
Screening between incompatible uses, mechanical equipment screening, and outdoor storage screening are spelled out in § 21.18.080.
District tables (e.g., Tables 2‑3, 2‑7, 2‑11) tell you which zones apply and the dimensional context (setbacks, height, landscaping obligation references). See the residential, commercial/manufacturing and mixed‑use tables (Tables 2‑3, 2‑7, 2‑11).

Important related processes: development and design review (see Fountain Valley Design Review), parking requirements (see Fountain Valley Parking), overlay rules (see Fountain Valley Overlay Districts), ADU rules (see Fountain Valley ADUs), and appeals/variances (see Fountain Valley Variances and Exceptions).

District-by-district (what landscapers/planners need to know)

Note: the Development Code organizes zones in chapters and tables; below I synthesize the landscaping/screening implications per district using the district tables and the landscaping/screening chapters cited.

R-1 (Single-Family Residential)

Purpose / typical uses: single‑family detached homes; accessory structures and limited ADUs. See Table 2‑3 and accessory standards.
Key dimensional/landscape standards: front yard setback 20 ft., side 5 ft. (10 ft. street side), rear 10 ft. for single‑story; site coverage 60% (50% on lots ≥10,000 sf); landscaping: single‑family parcels must maintain a minimum of 50% of the front yard setback as landscaping and front‑yard landscaping must be installed within six months of certificate of occupancy (or three months after sale) — Chapter 21.20 governs details. § 21.08.040 and § 21.20.040.
Screening/fence rules: fences/hedges over 3 ft are not allowed in the required front yard; side/rear fences/walls generally allowed up to 6 ft; chain‑link fences are prohibited within front yard setback in residential zones; barbed wire/razor wire prohibited. See § 21.18.070.
Where it applies: typical single‑family lots throughout residential neighborhoods (Table 2‑3).

GH (Garden Home / small‑lot residential)

Purpose / uses: small‑lot detached housing; density and setbacks determined by Table 2‑3 and commission approvals.
Landscaping/ screening implications: the same Chapter 21.20 landscaping rules apply; front‑yard and perimeter landscape maintenance obligations apply (see § 21.20.040). Verify specific setback/landscape expectations with the precise development approvals (many GH projects have tailored landscape plans).

R‑2 / R‑3 / R‑4 (Multi‑family residential)

Purpose / uses: duplexes through higher‑density multi‑family; see Table 2‑3/2‑4 for density and building standards.
Key landscaping specifics: multi‑family and nonresidential sites must provide 15% of the site as landscaping (Chapter 21.20 § 21.20.040(a)), and multi‑family projects have additional private open space and planting requirements. Parking lot landscaping rules (trees per X stalls and planters) apply to lots with ≥10 spaces.
Screening to adjacent residential: where nonresidential or commercial abuts residential, an opaque plant/solid masonry wall minimum 6 ft high is required along parcel boundaries; the maximum height and wall treatment rules defer to § 21.18.070. § 21.18.080.

C1 / CP / C2 / CM / M1 (Commercial & Manufacturing)

Purpose / uses: neighborhood & general commercial, commercial‑manufacturing, light industrial; see Table 2‑7 for exact uses and dimensional standards.
Landscaping requirements: nonresidential sites must supply 15% landscaping of the site (Chapter 21.20 § 21.20.040(a)). Parking areas adjacent to streets require a minimum 15‑foot planting strip (with 3 ft. shrubs); parking perimeter strips adjacent to other nonresidential uses require 4 ft strips with trees (6 trees per 100 lineal ft); parking next to residential uses must provide a solid masonry wall minimum 8 ft high plus a landscaped buffer yard minimum 10 ft wide (see § 21.20.040(d)).
Screen mechanicals/outdoor storage: roof/ground mechanicals, loading docks, refuse and outdoor materials must be screened from public streets and residential/open‑space areas; the director may require adjacent landscaping and architectural compatibility. § 21.18.080(c) and § 21.18.080(d).

MU‑1 and MU‑2 (Mixed‑Use)

Purpose / uses: higher‑intensity mixed residential and nonresidential projects; special dimensional rules in Table 2‑11 (setbacks, step‑backs, FAR, density).
Landscaping/screening takeaways: landscaping obligations refer to Chapter 21.20 (but some MU development exceptions exist where § 21.20.040 landscape area requirements may be adjusted per Table 2‑11). MU projects must provide residential buffers (building orientation, walls, and landscaping) to separate residential uses from service/parking/trash areas. See the MU development standards and § 21.18.080 for screening performance.

Quick reference table — decision‑relevant landscaping & screening standards

How the rules are applied (practical guidance)

Landscape plans: Where the permit is discretionary (conditional use, precise plan, development review) or when the water‑efficient landscaping rules apply, the city requires a comprehensive landscape and irrigation plan signed by a California‑licensed landscape professional. § 21.20.050(a)(1).
Parking designs must show planters, interior trees, and perimeter planting strips to meet the tree‑per‑stall and planter size rules; parking lot perimeter strips near residential uses must include the masonry wall + 10‑ft buffer. § 21.20.040(d). See the city's parking rules for interplay with parking calculations.
Screening mechanicals/refuse: show elevations and materials demonstrating architectural compatibility and adjacent landscaping where the director requires it (mechanicals must be screened from streets and residential/open space). § 21.18.080(c).
Fences & walls: front yard and corner visibility limitations are strict — do not design a front yard fence or hedge taller than 3 ft in the required front setback area; chain link in front setbacks is prohibited in residential zones. § 21.18.070.
Design/precise plan: many non‑R‑1 projects require a precise plan of design and the commission may impose landscape/screening conditions; see Fountain Valley Design Review. § 21.44.030–060.

Checklist (what to include with your application)

Scaled site plan showing all existing and proposed landscape areas, planting strips, and planter islands (label areas in sq. ft.) — supports § 21.20.040.
Landscape & irrigation plan signed by a California‑licensed landscape professional when required (discretionary permits or water‑efficiency rules) — § 21.20.050(a)(1).
Plant schedule (botanical/common names), container sizes, spacing and quantities — § 21.20.050(a)(1).
Parking plan showing tree counts (1 per 10 stalls), planter dimensions (min. 4 ft interior), and perimeter planting widths — § 21.20.040(d)(2).
Elevation detail for any screening walls/fences showing materials and heights; reference front‑yard 3‑ft limit and side/rear 6‑ft limit — § 21.18.070.
Screening details for mechanical equipment, loading docks, and refuse areas — § 21.18.080(c).
If project abuts residential, show proposed masonry wall and planting buffer per § 21.18.080(b) and § 21.20.040(d)(1–C).
If requesting deviations (e.g., taller wall), include a Minor Variance or Variance application as permitted by Table 4‑2 / § 21.50.030.

Risks & Ambiguities

Issue	Why it matters	What to verify
Tree removal / species approvals	The code requires plant lists and sizes but does not include a city tree‑removal permit procedure in the retrieved materials	Verify whether a separate tree‑removal permit or historic/tree protection ordinance applies — Not found in retrieved materials; verify with the jurisdiction
Exact acceptable plant palettes / water‑use calculators	Chapter 21.20 requires water‑efficient plans but the retrieved excerpts do not show a full plant list or water‑budget worksheet	Confirm if additional water‑efficiency or local xeriscape standards apply (city or state) — Verify with the jurisdiction; see § 21.20.050.
Wall height measurement at irregular grades	Height is measured from finish grade; but grade differences along long walls can change permitted heights	Confirm grade baseline with the planning director; reference § 21.18.050 for height measurement and § 21.18.070 for walls.
Corner cutback vs. decorative low wall	Corner sight triangle limits “objects” to 3 ft — landscaping mounding or low walls may violate visibility rules	Confirm whether proposed planters/low walls comply with § 21.18.040(b) and public works sight‑distance standards.
Mixed‑use density/landscape tradeoffs	Some MU standards allow alternative landscape/counting methods; the tables reference exceptions	Cross‑check Table 2‑11 provisions with Chapter 21.20 when preparing calculations — § 21.20.040 and Table 2‑11.

Plain‑English summary

Fountain Valley requires both minimum landscape area and specific screening where uses meet (for example, masonry walls plus planting when commercial touches residential), limits front‑yard fence heights to 3 feet, and requires parking lots to include planting strips and trees (1 tree per 10 stalls). Landscape plans are required for discretionary permits and the city enforces planting sizes, planter dimensions and maintenance standards — see § 21.20.040, § 21.20.050, § 21.18.070, and § 21.18.080 for the controlling rules.

Frequently asked questions

Do I need a landscape plan for a single‑family home in Fountain Valley?

If your work is part of a discretionary permit or subject to the water‑efficiency landscape provisions, you must provide a comprehensive landscape and irrigation plan signed by a California‑licensed landscape professional — see § 21.20.050(a)(1). For routine single‑family lot landscaping installed by the homeowner, the code allows the homeowner to install landscaping without prior city approval but the yard must still meet the city's minimums (e.g., 50% of the front yard setback in single‑family zones). § 21.20.050 and § 21.20.040(b).

What are the fence height limits in front yards?

Fences, walls, lattice work, hedges and dense shrubs/trees greater than 3 ft in height are not allowed within a required front yard. Side/rear yard fences/walls are generally limited to 6 ft (exceptions for arterial subdivision walls or agency‑required walls exist). See § 21.18.070(1–4).

If my commercial parking lot backs to homes, what do I have to provide?

When a nonresidential parking area adjoins residential uses you must provide a solid masonry wall minimum 8 ft high plus a landscaped buffer yard a minimum 10 ft wide; for parking lot interior landscaping you must also meet tree‑per‑stall and planter‑size rules (e.g., 1 tree per 10 stalls, planters min. 4 ft interior). See § 21.18.080(b) and § 21.20.040(d).

How much of my commercial site must be landscaped?

Nonresidential and multi‑family uses must provide and maintain 15% of the site in landscaping (setbacks and other unused site areas may count). See § 21.20.040(a).

Are chain‑link fences allowed along front yards in residential zones?

No — the Development Code explicitly prohibits chain‑link fences within the required front yard setback in all residential zoning districts. § 21.18.070(6).

Can I request a higher wall or lower landscaping percentage?

Minor variances can be requested in limited situations (Table 4‑2) — for example a minor variance may increase fence/wall height by up to 2 ft; larger deviations require a full Variance application. See Table 4‑2 and § 21.50.030.

Does screening for mechanical equipment require a masonry wall?

No — mechanical equipment, loading areas and refuse must be screened from streets and residential/open space, and the method must be architecturally compatible; the code expressly allows plant material, solid walls, or other compatible screening, and the director may require adjacent landscaping consistent with Chapter 21.20. § 21.18.080(c).

Do MU (mixed‑use) projects follow the same landscaping rules?

Yes — MU zones reference Chapter 21.20 for landscaping generally, but MU standards (Table 2‑11) may adjust how certain perimeter or interior open spaces are counted. Always reconcile Table 2‑11 with Chapter 21.20 when calculating compliance. § 21.20.040 and Table 2‑11.

Where do I find parking‑landscape requirements for plan submittal?

Parking lot landscape obligations (perimeter strips, tree counts, planters, minimum planter dimensions) are in § 21.20.040(d); coordinate these with the Fountain Valley Parking and show them on site and grading plans.

Are front‑yard hedges considered "fences" under the code?

Yes — the code groups hedges and dense shrub/tree growth with fences and screens; any hedge/planting that creates an obstruction taller than the front‑yard limit is regulated under § 21.18.070(1).
