Glendora — Landscaping and Screening

Landscaping and Screening under the Glendora local zoning and planning code, with the controlling citations.

Quick answer

Glendora requires landscaped area minimums by use—15% for residential and medical, 10% for commercial/mixed-use, and 5% for industrial—and mandates street-yard trees and shrubs plus parking-lot landscaping of at least 10% with 1 tree per 8 spaces (§ 21.03.015C–H). Front-yard fences are limited to 4 ft if open (3 ft if solid), side/rear to 6 ft, and a 6 ft solid masonry wall is required where non-residential abuts residential (§ 21.03.010F). Tree removals (DBH ≥8") tied to approvals trigger replacements per tables (§ 21.03.015J).

Overview

Glendora centralizes landscaping and screening rules in Title 21 — Zoning. The core citywide standards for planted areas, trees, parking-lot shading, and buffers appear in § 21.03.015 and the fence/wall rules and screening of equipment in § 21.03.010(F–G). Several Specific Plan districts carry their own, different landscaping and fence material standards (Article 12 and Article 13). Mixed-use projects have extra screening/location rules for trash, loading, lighting and equipment in § 21.10.360.

The most common edge condition: where a non-residential use abuts a residential zone, Glendora requires a solid masonry wall at least 6 feet high along the shared property line to buffer impacts (§ 21.03.010F.3.c).

Citywide landscaping and screening standards (apply unless a Specific Plan overrides)

Applicability thresholds. The landscape standards apply to: new residential with 11+ units; new commercial over 1,000 sf; major additions/site work affecting 25%+ of gross site; parking reconfigurations affecting 10+ spaces; publicly accessible private open space (§ 21.03.015A).
MWELO triggers. California’s Model Water Efficient Landscape Ordinance applies to new landscape areas ≥500 sf and rehabilitated landscape areas ≥2,500 sf when a permit, plan check, or design review is required—regardless of the thresholds above (§ 21.03.015B).
Minimum landscaped area by use (of gross lot area): Residential 15%; Commercial and Mixed-Use 10%; Medical 15%; Industrial 5% (§ 21.03.015C).
Where landscaping must go. Required front/side/rear setbacks; common open space; along pedestrian paths/entries; within and next to parking lots and drive aisles; maintain clear sight distance and comply with fence/wall visibility in § 21.03.010F (§ 21.03.015D).
Planting system and materials. Live groundcover/shrubs/vines only (no gravel/bark as “landscape”); minimum 1-gallon shrubs; maintain sightlines at maturity; trees at 1 per 500 sf of open space or 1 per 50 linear feet of frontage, whichever yields more; multi-trunk trees count as 2 (§ 21.03.015E).
Species diversity on lots ≥0.5 acre: no more than one-third of any single species, genus, or family (§ 21.03.015E.2).
Water efficiency. Mulch 2–4 inches in all new planting areas; comply with MWELO where triggered (§ 21.03.015F).
Setback landscaping. Street-facing setbacks must include: one 36-inch box shade tree per 50 linear feet of lot width; shrubs at 1 per 4 square feet; hardscape limited to 50% of the landscaped setback (except in the Civic Center Area Plan district); parking-adjacent setbacks require a 30–36 inch high landscaped or low wall/berm screen (§ 21.03.015G).
Parking-lot landscaping. Provide a minimum 5-foot perimeter landscape strip along public ROW with one 24-inch box tree per 35 linear feet and continuous shrubs; landscape at least 10% of interior parking area; plant 1 tree per 8 spaces; tree planters at least 4'x8' (4'x4' diamond planters allowed, but limited to 50% of total onsite planters); allow 2-foot vehicle overhang where adjacent plantings are <18 inches tall (§ 21.03.015H).
Tree sizes. Minimum 15-gallon for new trees; include a mix that also uses 24", 36", 48" box sizes (§ 21.03.015I).
Urban tree preservation and replacement. Removal regulation applies to private-parcel trees: DBH ≥8", non-emergency, outside ROW, and associated with any discretionary land-use/zoning application including MWELO submissions (§ 21.03.015J.1). Replacement ratios vary by native/non-native and size; on-site replanting within 24 months and 3-year maintenance, or payment-in-lieu to the City Tree Fund, or a hybrid of both; species/location approved by the City Forester with priority to native/drought-tolerant species (§ 21.03.015J.2–J.6).

Citywide fences, walls, buffers, and equipment screening

Heights in yards. In front setbacks: up to 4 ft if at least 50% open; up to 3 ft if solid; or 3 ft solid bottom + 1 ft open top (max 4 ft). In side/rear yards: up to 6 ft behind the front setback. Corner visibility: no solid fence/wall over 30 inches within 10 ft of street intersections (§ 21.03.010F.1).
Along rail/highway rights-of-way. Up to 8 ft allowed for noise mitigation; higher walls require an acoustical study and approval (§ 21.03.010F.1.d).
Prohibited materials citywide (residential, commercial, mixed-use). Barbed/razor/electrified; reflective/unfinished metal; unfinished wood/plywood; broken glass/sharp features (§ 21.03.010F.1.e).
Multifamily (11+ units). Perimeter fencing/walls on all side/rear lines; articulation required for solid walls >50 ft (jogs, pilasters, material variation, or landscaped pockets/vines); decorative cap required; limited material palette; front-yard fencing must be visually open (e.g., wrought iron/tubular steel); coordinate colors with primary buildings (§ 21.03.010F.2).
Mixed-Use, Commercial, Industrial. Fences/walls only where needed for security/screening/buffering; no fences/walls in mixed-use open spaces or along street frontages except where screening utilities/refuse or along side/rear lines; where non-residential abuts residential: build a 6-ft high solid masonry wall; street-facing walls/fences must be softened by landscaping (berms/hedges/planter strips/vines) (§ 21.03.010F.3).
Mechanical and utility equipment. Screen ground-mounted equipment with landscaping of sufficient height/maturity to hide it at installation or within one growing season, or by architectural means (§ 21.03.010G).

Mixed-use screening specifics

For mixed-use projects: enclose and screen trash areas so they’re not readily identifiable from streets; locate and fully screen loading and solid-waste storage; shield commercial lighting from residences and residential units from commercial sign lighting; screen exterior equipment, with noise-reducing screens/insulation as needed; prioritize rooftop screening for non-solar equipment (§ 21.10.360.B.3–B.8, B.11.f).

Specific Plan districts with tailored landscaping/screening

Objective Design Standards do not apply in several Specific Plans (including the Glendora Commercial Specific Plan and other SPs) (§ 21.15.020B). In these areas, Article 12 and Article 13 provisions control fences, walls, plant palettes, and maintenance.

Public areas and perimeter walls/fences. Chain link, barbed wire, one-sided wood, and grapestake are prohibited; open-space frontage must be wrought iron or tubular steel; acceptable perimeter walls include planted hedges, stone, masonry with plaster, adobe block, slump block with stucco; combinations may use a 12-inch masonry base with tubular steel above (≤6 ft total). Front yard fences up to 4 ft if at least 50% open; behind front setback, up to 6 ft (§ 21.13.270.C).
HOA-maintained areas. HOA assumes maintenance of linear park areas, man-made slopes, “letter lots,” and certain drives; chain-link fencing is prohibited; guidelines emphasize large-mass plantings, minimizing turf, firewise/native species, and terraced retaining walls in earth tones; a detailed plant palette of approved trees, vines, groundcovers, turf types, and shrubs is provided (§ 21.13.350.F–G).
Private residential dwelling landscaping (SP). Use drought-tolerant/arid/ornamental plants; integrate natives and firewise species in High Fire Hazard Severity Zones; limit turf; avoid ladder fuels; emphasize natural plant forms; limit certain hardscapes (patterned/stamped concrete and asphalt are prohibited); encourage permeable paving and water infiltration to landscaped areas; fence/wall materials should blend with architecture and landform, with wrought iron encouraged to maintain openness (§ 21.13.330.A–B, C).
Additional SP fence material controls. Visible walls/fences must be durable and well-detailed; permitted materials include stone, stucco, split-face or slump block, masonry, brick, wrought iron/tubular steel; prohibited: barbed wire, chain link, chicken wire, most metals other than wrought iron/galvanized tubular steel for view fencing, corrugated metal, aluminum, and wood/plywood; some interior lot walls specified as slump stone (§ 21.12.290).

Hillside development and landscape screening

In hillside contexts, grading is tightly limited; structures should fit terrain; design should preserve native plant materials and use plant materials and ridgelines as backdrops, concealing manufactured slopes—reinforcing the role of landscaping as visual screening (§ 21.04.030).

Practical notes and comparisons

The minimum landscaped area is use-based, not zone-letter-based. Mixed-use projects use the 10% minimum for the site, plus they must meet trash/loading/equipment screening specifics unique to mixed-use (§ 21.03.015C; § 21.10.360.B.3–B.8).
Setback plant density is aggressive (1 shrub per 4 sf). Budget for irrigation/mulch and confirm sight triangles with your civil/traffic team because shrub masses cannot block visibility (§ 21.03.015G; § 21.03.015D.2; § 21.03.010F).
Parking-lot tree/planter geometry is specific. The small “diamond” planters are capped at half of onsite planters—many designs run afoul of this without early layout checks (§ 21.03.015H.2.c.i).
If you’re adjacent to homes, start with a 6-ft masonry wall in your base plan set and layer hedges/berms/climbing vines to soften street-facing runs (§ 21.03.010F.3.c–d).
In Specific Plans, chain-link is broadly prohibited and curated palettes/materials dominate. Pull the applicable Article 12/13 pages early; the SP can override default citywide rules (§ 21.13.270; § 21.13.350; § 21.13.330; § 21.12.290; see Glendora Overlay Districts).

Checklist

Confirm which framework governs the site: citywide standards in § 21.03.015/§ 21.03.010 or a Specific Plan in Article 12/13. If in an SP, follow those materials/palette/height rules.
Determine applicability trigger: 11+ units, >1,000 sf commercial, 25%+ site change, 10+ parking spaces reconfiguration, or public-access private open space (§ 21.03.015A).
Test MWELO thresholds: ≥500 sf new or ≥2,500 sf rehab landscaped area with a permit/plan check/design review (§ 21.03.015B).
Calculate minimum landscaped area by use (10%–15%, or 5% for industrial) (§ 21.03.015C).
Place landscaping in setbacks, common open spaces, along pedestrian paths/entries, and in/next to parking (§ 21.03.015D).
Setback design: 36" box tree per 50 lf lot width; shrubs at 1/4 sf; setback hardscape ≤50% (Civic Center exception) (§ 21.03.015G).
Parking-lot landscaping: 5-ft perimeter strip; interior ≥10%; 1 tree/8 spaces; ensure ≥4'x8' planters; limit 4’x4’ diamonds to ≤50% of all planters (§ 21.03.015H).
Count trees: 1 per 500 sf open space or per 50 lf frontage (whichever needs more); use live plants, 1-gallon minimum; mulch 2–4 inches; check species diversity if lot ≥0.5 acre (§ 21.03.015E–F).
Fences and walls: apply height/material limits; provide 6-ft solid masonry wall when abutting residential; soften street-facing walls with landscape (§ 21.03.010F).
Screen equipment with live landscaping or architectural screening that hides it immediately or within one growing season (§ 21.03.010G).
If removing a DBH ≥8" tree in a qualifying case, prepare replacement plan or fee-in-lieu per tables; schedule planting within 24 months and 3-year maintenance; obtain City Forester approval (§ 21.03.015J).
Where mixed-use: enclose/screen trash; fully screen/locate loading away from residences; shield lighting; screen rooftop/exterior equipment (§ 21.10.360.B.3–B.8, B.11.f).

Risks & Ambiguities

Issue	Why it matters	What to verify
Civic Center Area Plan exception	Setback hardscape cap (50%) doesn’t apply there	Whether your parcel is within that area and any alternate cap (§ 21.03.015G.3).
“Open space” basis for tree count	Tree count uses “open space” or frontage—definitions affect quantity	How “open space” is measured on your site plan (§ 21.03.015E.1.b).
Diamond planters cap	Overuse of 4’x4’ diamonds can make a plan non-compliant	Count of all onsite planters and percent that are 4’x4’ diamonds (§ 21.03.015H.2.c.i).
Corner visibility envelope	Fence/wall height near intersections is restricted	How and from where the 10-ft triangle is measured in the field (§ 21.03.010F.1.c).
Native vs non-native classification	Drives tree replacement ratios	Species list and City Forester’s determination (§ 21.03.015J.2, J.6).
Multi-trunk DBH calculation	Affects replacement DBH sum and counts	Arborist method for summing DBH where trunks ≥4" (§ 21.03.015J, “Multi-Trunk Trees”).
Specific Plan precedence	SPs override citywide rules	Whether your site is within Article 12/13 SP boundaries (§ 21.15.020B; § 21.13.270; § 21.12.290).
Mixed-use screening vs open-space fencing	Fences prohibited in mixed-use open spaces	Whether proposed fencing is only for screening/utilities or along side/rear lines (§ 21.03.010F.3.b).

Plain-English Summary

If you build a larger residential project, a new commercial/industrial development, or rework a big chunk of your site or parking, you must landscape a set share of the lot, add street-yard trees and shrubs, and shade the parking with trees. Fences in front yards are short and open; taller 6-foot walls go on the sides/rear, and non-residential sites next to homes must build a 6-foot masonry buffer. Specific Plans in Glendora may require different fence materials and plant palettes—check those first.

Frequently asked questions

How much of my commercial site must be landscaped in Glendora?

At least 10% of the gross lot area must be landscaped for commercial and mixed-use projects that meet the applicability thresholds; medical uses require 15%. Industrial sites must landscape at least 5% (§ 21.03.015C.2–4). These apply to new commercial over 1,000 sf, major site changes affecting 25%+ of the site, and certain parking reconfigurations (§ 21.03.015A).

What are Glendora’s limits for fences in the front yard?

In front setbacks, fences and walls can be up to 4 feet high if at least 50% open; solid fences are limited to 3 feet, or you may do 3 feet solid plus 1 foot of open top, total 4 feet (§ 21.03.010F.1.a). Corner lots must also keep solid fences/walls over 30 inches out of the 10-foot intersection visibility zone (§ 21.03.010F.1.c).

Do parking lots need trees and interior landscaping?

Yes. Provide a 5-foot perimeter planting strip with one 24-inch box tree per 35 linear feet and continuous shrubs, landscape at least 10% of the interior parking area, and plant one tree per eight spaces. Tree planters must be at least 4'x8'; 4'x4' “diamond” planters are allowed but limited to half of all onsite planters (§ 21.03.015H).

When does Glendora require tree replacement for removals?

When removing a private-tree of DBH ≥8 inches in connection with discretionary land use/zoning actions (including MWELO), replacement is required per native/non-native tables. You must replant within 24 months and maintain for three years, or pay a fee-in-lieu (or do a hybrid), with species/location approved by the City Forester (§ 21.03.015J).

Are chain-link fences allowed in Glendora?

Chain link is broadly prohibited within certain Specific Plan areas for perimeter/public-facing conditions, and HOA-guided areas expressly ban it (§ 21.13.270.C.2; § 21.13.350.F.7). Citywide, additional prohibited materials include barbed/razor/electrified fencing, reflective/unfinished metal, and unfinished wood/plywood (§ 21.03.010F.1.e).

What screening is required next to homes for a commercial or industrial site?

A solid masonry wall at least 6 feet high must be built along the shared property line where a non-residential use abuts a residential zone (§ 21.03.010F.3.c). Street-facing walls/fences must also be softened with landscaping such as berms, hedges, planter strips, or vines (§ 21.03.010F.3.d).

Does MWELO apply even if my project is small?

Yes. MWELO applies whenever new landscaping totals 500 sf or more, or rehabilitated landscaping totals 2,500 sf or more, if a permit, plan check, or design review is required—regardless of other threshold exemptions (§ 21.03.015B).

What is required in street-facing setbacks?

Provide one 36-inch box shade tree per 50 linear feet of lot width and shrubs at a density of one per four square feet; hardscape is limited to 50% of the landscaped setback (except in the Civic Center Area Plan) (§ 21.03.015G).

How should equipment be screened?

Ground-mounted mechanical/utility equipment must be screened with live landscaping tall/mature enough to fully obscure it at installation or within one growing season, or with architectural screening (§ 21.03.010G).

Can I put fences in mixed-use open spaces?

No. In mixed-use developments, fences and walls are prohibited in open space areas and along street frontages, except along side/rear property lines or when required for screening utilities, mechanical equipment, or trash enclosures (§ 21.03.010F.3.b; § 21.10.360.B.3–B.4).
