Los Banos — Landscaping and Screening

Q: What are Los Banos’ fence height and setback rules for single‑family lots?

Fences are commonly allowed at the property line ( fence zero ft ), but walls or fences over 3 ft are regulated by yard/setback rules; single‑family front yard setback is 20 ft (cul‑de‑sac 10 ft ). See the single‑family placement and setback rules in § 9-3.609 and the R‑zone setback sections.

Q: Are there special landscaping setbacks when industrial zones border residential?

Yes — where a Light Industrial ( L‑I ) yard is adjacent to R‑1 or R‑2 , the code requires a 25 ft landscape setback; otherwise the L‑I district may have no required setback. See § 9-3.1408(a) .

Q: Is turf allowed everywhere?

No. Turf is prohibited on slopes greater than 25% where the toe of slope is adjacent to impermeable hardscape, and high‑water plants (including turf) are prohibited in street medians. See § 9-6.03.06(d–e) .

Overview

This page summarizes what the Los Banos zoning and planning ordinance requires for landscaping, screening, buffers, fences, walls, and trees. It is focused on the local Zoning Title and the City’s water-efficient landscape (WELO-style) requirements: submittals, hydrozones, turf restrictions, irrigation and post-installation certification. For site-wide projects expect coordinated review with site plan and parking design, design review, and applicable overlay districts or development standards to which your property is subject. Verify parcel‑specific requirements with the Community Development Department.

Key controlling code references used below include the City’s site plan and design review rules (§ 9-3.2317 / § 9-3.2318) and the City’s local water-efficient landscape chapter (Article 9-6.03, e.g., §§ 9-6.03.03 – 9-6.03.12) for landscape submittals, plant selection, irrigation design, and the certificate of completion.

District-by-district rules (landscaping & screening)

Below are the Los Banos districts where the code explicitly prescribes landscaping, screening or setback rules. Each district subsection shows the purpose (brief), typical uses (as they relate to screening/landscape), the most relevant dimensional/landscape/screening rules, and where that rule appears in the code.

R-1 (Low Density Residential)

Purpose / typical uses: Single‑family homes and accessory structures; residential landscaping and street frontage planting are expected. See general single‑family district development standards.
Key standards:
- Front setback: 20 ft minimum (cul‑de‑sac bulbs may be reduced to 10 ft). (§ 9-3.609)
- Fences: fences are generally permitted to the property line (fence zero ft setback) except where other provisions apply; fences/walls over 3 ft are regulated by yard rules. (§ 9-3.609; see §§ on setbacks & fences)
- Where site plan or design review applies, the Planning Commission evaluates landscape materials, tree selection, and methods used to screen mechanical equipment. (§ 9-3.2318(c))

R-2 (Medium Density Residential)

Purpose / typical uses: Duplexes, small multiunits; higher lot coverage than R-1, but explicit minimum landscape requirements apply for open space.
Key standards:
- Lot coverage / open space: Not more than 70% of lot area may be building/parking/hardscape; remaining 30% must be landscaping, lawns or outdoor recreation. (§ 9-3.707)
- Setbacks: Front 20 ft, side interior 5 ft (fences often allowed at 0 ft), rear 10–20 ft depending on accessory structures. (§ 9-3.708)
- Mobile home subdivisions in R-2/R-3 must keep street‑front setback areas planted with grass, shrubs or trees and maintained. (§ 9-3.1702)

R-3 (High Density Residential)

Purpose / typical uses: Multi‑family developments (apartments); code requires landscape area per unit and landscape plan approval.
Key standards:
- Open space: Minimum 200 sq ft per family unit of landscaped/open area; overall 30% of lot reserved for landscaping/open space where density rules apply. (§ 9-3.809, 9-3.807)
- Setbacks & fences: Front 15 ft (cul‑de‑sac 10 ft allowed); fences generally allowed at 0 ft (fences/walls > 3 ft are subject to setback rules). (§ 9-3.808)
- Trash enclosures: trash/garbage areas must be surrounded on at least three sides by a 5 ft block wall (landscape and screening around service areas). (§ 9-3.811(c))

L‑I / Light Industrial

Purpose / typical uses: Light manufacturing, warehouses, contractor yards; outdoor storage and equipment areas are common and specifically regulated for screening.
Key standards:
- If a yard in L‑I is adjacent to R-1 or R-2, a 25 ft landscape setback is required; otherwise none are prescribed. (§ 9-3.1408(a))
- Screening: All manufacturing/fabrication storage and equipment areas must be screened by solid fences, walls, or screen planting not less than 6 ft in height. (§ 9-3.1403)
- Site plans and elevations including minimum landscaping per City Standards and Specifications are required for project approval. (§ 9-3.1409)

I (General Industrial)

Purpose / typical uses: Heavier industrial uses; outdoor storage/operations require screening and distance from residential zones.
Key standards:
- Facilities that store materials or operate outdoors must be screened from the public right‑of‑way by walls, fences and/or screening landscaping and may be required to be wholly enclosed for certain uses; minimum setbacks/landscape per underlying district. (§ 9-3.2906(b, d))
- If within 500 ft of residential zones, operating hours and additional mitigations may be imposed. (§ 9-3.2906(h))

Public Facilities (PF)

Landscaping and screening are handled as part of site plan review; appropriate setbacks, lot coverage, building height—and landscaping—are determined through PF site plan review for compatibility. (§ 9-3.1605)

Mobile Home Subdivision (R-2 / R-3 specific) — landscaping & fences

Setback areas abutting streets must be planted with grass, shrubs, trees or other decorative materials and kept maintained. (§ 9-3.1702)
Fences in the mobile home subdivision standards are separately regulated—see § 9-3.1703. (§ 9-3.1703)

Decision‑relevant standards and screening table

Requirement / Topic	What the code says (decision‑relevant value)	Code Reference

Guidance & practical notes (plain-English synthesis)

If your project includes new or rehabilitated landscape over a threshold (see § 9-6.03 definitions and applicability), you must prepare and submit a Landscape Documentation Package (LD Package) that contains a detailed landscape plan, irrigation plan, water‑budget calculations (MAWA/ETWU), soil report, grading plan and the Water Efficient Landscape Worksheet. The City reviews the LD Package as part of plan check, site plan or design review. (§ 9-6.03.03, § 9-6.03.01, § 9-3.2319)
Industrial and contractor sites are explicitly required to screen outdoor storage and equipment with solid fences/walls or planting at least 6 ft high; if your site is in L‑I and borders residential, plan on a 25 ft landscape buffer. (§ 9-3.1403, § 9-3.1408)
Turf and plant selection: pick plants by hydrozone and follow the plant factor rules; avoid high‑water use plants in medians and avoid turf on steep slopes (> 25% toe‑to‑hardscape). Tree spacing and mature size must be considered in the landscape plan (City Standards and the code reference local tree/shade canopy rules). (§ 9-6.03.06)
Irrigation plans must be prepared to industry standards and signed by a licensed landscape professional or certified irrigation designer; irrigation controllers and scheduling must support water efficiency and the City may require irrigation audits and the Certificate of Completion. (§ 9-6.03.07(b), § 9-6.03.09, § 9-6.03.10)
Design review and site plan review evaluate landscaping as a material part of project aesthetics and compatibility: the Planning Commission will review types of planting, tree locations, fences/wall materials, screening of mechanical equipment and lighting. Expect conditions of approval tying plant types and screening treatments to the permit. (§ 9-3.2318(c), § 9-3.2320)

Note: When a project triggers design review, the project must submit full site plans showing fences and walls (location, height, materials) and the landscape plan (showing existing and proposed trees and shade canopy compliance). (§ 9-3.2319(b)(1–2))

Checklist

Determine whether your project meets the trigger for the Landscape Documentation Package (new/rehab thresholds). (§ 9-6.03).
Prepare a Landscape Documentation Package with: project info, Water Efficient Landscape Worksheet (MAWA/ETWU), soil report, landscape design plan (hydrozones), irrigation design plan, grading plan. (§ 9-6.03.03, § 9-6.03.04).
For multi‑family or commercial developments, show open space / landscape percent, tree canopy, and planting palettes consistent with City Standards. (§ 9-3.807, § 9-3.809, § 9-6.03.06).
If in or adjacent to L‑I or industrial use, plan for 6 ft screening and a 25 ft buffer if bordering R‑1/R‑2. (§ 9-3.1403, § 9-3.1408).
Include fences/walls (location, heights, materials) and show any fences > 3 ft in site plan submittal. (§ 9-3.2319(b)(1)).
Prepare irrigation schedule / controller programming and plan for irrigation audit and Certificate of Completion after installation. (§ 9-6.03.10, § 9-6.03.09).
Coordinate landscape and screening with parking layouts, design review, and any overlay districts that impose additional standards. (§ 9-3.2318).

Risks & Ambiguities

Issue	Why it matters	What to verify
When exactly the Landscape Documentation Package is required	Applicability thresholds (project size/type) determine whether WELO-style submittal is mandatory.	Code shows the required LD Package elements (§ 9-6.03.03) but does not list numeric thresholds in the retrieved excerpts. Verify thresholds and exemptions with the City.
Fences at property lines vs. yard setback rules	Many zones allow fence zero ft but walls/fences taller than 3 ft are subject to yard rules and may trigger fence‑height limits or reverse‑corner requirements.	Confirm fence‑height rules, visibility triangle and any separate fence code or standards in Development Standards. (§ 9-3.608–9-3.812 area; specific fence section not fully shown)
Exact plant lists and local approved tree guidelines	The ordinance references City Standards and Specifications for approved plant/tree lists but those lists are not in the retrieved text.	Obtain City Standards and Specifications and the approved plant list; verify fuel modification / fire‑safety lists if in WUI areas. (§ 9-6.03.06, City Standards ref.)
L‑I buffer applicability & measurement	The 25 ft landscape setback applies when L‑I is adjacent to R‑1/R‑2, but how the buffer is measured on irregular parcels or where property lines are non‑orthogonal is not detailed here.	Verify buffer measurement method and whether screening may be shifted on site through mitigation or Planning Commission conditions. (§ 9-3.1408(a))
Street‑median and right‑of‑way plant rules	Medians prohibit high‑water plants/turf, but jurisdiction of median planting (City vs. developer) and maintenance responsibilities are not fully specified.	Confirm with Public Works / City Standards who installs/maintains medians and permitted species. (§ 9-6.03.06(e))
Fire safety / WUI planting requirements	The code references fuel modification guidelines and PRC 4291 for defensible space, but detailed local fire‑smart plant rules are not all present.	Verify with Fire Department and consult any adopted local Fuel Modification Plan; otherwise follow referenced State code. (§ 9-6.03.06(f))

Plain-English Summary

Los Banos requires most significant new or rehabilitated landscapes to submit a detailed Landscape Documentation Package (design + irrigation + water budget + soil + grading), enforces water‑efficient planting and irrigation (MAWA/ETWU limits, hydrozones, turf limits), and requires screening for industrial/outdoor storage (solid walls or plant screens, typically 6 ft) and landscape buffers where industrial borders residential (often 25 ft). Expect plan review, irrigation audits, and a post‑installation Certificate of Completion. Verify parcel‑specific triggers and City Standards for plant lists and measurement rules.

Frequently asked questions

What triggers a Landscape Documentation Package in Los Banos?

The ordinance requires a Landscape Documentation Package for projects subject to the City’s landscape chapter; the package contents are specified in § 9-6.03.03 (project info, Water Efficient Landscape Worksheet, soil report, landscape, irrigation, grading plans). The retrieved excerpts show the required documents, but the numeric thresholds or dollar/area triggers are not shown here — verify applicability with the City.

What are Los Banos’ fence height and setback rules for single‑family lots?

Fences are commonly allowed at the property line (fence zero ft), but walls or fences over 3 ft are regulated by yard/setback rules; single‑family front yard setback is 20 ft (cul‑de‑sac 10 ft). See the single‑family placement and setback rules in § 9-3.609 and the R‑zone setback sections.

Do industrial yards need screening? If so, how tall?

Yes. Manufacturing, fabrication and outdoor equipment/material storage areas must be screened by solid fences, walls, or screen plantings not less than 6 ft in height. See § 9-3.1403 for the L‑I/I standards.

Are there special landscaping setbacks when industrial zones border residential?

Yes — where a Light Industrial (L‑I) yard is adjacent to R‑1 or R‑2, the code requires a 25 ft landscape setback; otherwise the L‑I district may have no required setback. See § 9-3.1408(a).

What does Los Banos require for irrigation and water budgets?

Projects must provide an irrigation design plan and a Water Efficient Landscape Worksheet that demonstrates the MAWA/ETWU and meets ETAF limits (ETAF 0.55 for residential, 0.45 for non‑residential). Irrigation plans must show controllers, valves, flow rates and be signed by a qualified designer. See § 9-6.03.04, § 9-6.03.07(b).

Is turf allowed everywhere?

No. Turf is prohibited on slopes greater than 25% where the toe of slope is adjacent to impermeable hardscape, and high‑water plants (including turf) are prohibited in street medians. See § 9-6.03.06(d–e).

Will the City require a post‑installation certificate or audit?

Yes. The ordinance requires a Certificate of Completion after installation that includes certification the landscape was installed per the approved package, irrigation scheduling parameters and an irrigation audit report. See § 9-6.03.09 and § 9-6.03.12.

Do I need to show fences and walls in a site plan submittal?

Yes. For projects subject to site plan or design review you must show driveways, fences and walls (location, height and materials) and landscapings — see the submittal requirements in § 9-3.2319(b)(1–2).

What if my project is in a historic area or overlay district?

Overlay or historic district rules may impose additional planting, screening or materials requirements; coordinate landscaping with the applicable overlay districts and Historic Preservation policies. The base zoning rules require landscaping and screening as shown in the codes cited here; overlay specifics are not all contained in the retrieved excerpts. Verify overlay requirements.

Are there special fire‑safety planting rules I must follow?

The landscape chapter references fuel modification and defensible space requirements (Public Resources Code § 4291) and local Fuel Modification Plan guidelines; the ordinance requires fire‑safety considerations in landscape plans for fire‑prone areas. For detailed plant restrictions in WUI zones, confirm with the local Fire Authority. See § 9-6.03.06(f).

How does landscape control interact with parking layouts?

Landscape plans must indicate parking, entrances and the direction of traffic flow and parking lot landscaping is part of site plan review; coordinate landscape islands, shade trees, drainage and stormwater capture with parking design and the LD Package requirements. See site plan submittal rules § 9-3.2319(b)(1–2) and WELO recommendations for stormwater capture.
