South El Monte — Landscaping and Screening

Q: What landscaping is required in South El Monte parking lots?

At least 5% of the total parking area must be landscaped, with planter curbs at least 6 inches (concrete) or 8 inches (masonry) and an accepted irrigation system or hose bibs within 50 feet. The 5% should be distributed as evenly as possible across the lot (§ 17.06.070; § 17.08.080; § 17.16.030(4)-(6); § 17.09.070).

Q: How tall can a front yard fence be in South El Monte residential zones?

In R‑1, R‑2, and R‑3, a sight‑obscuring fence in the required front yard may be up to 42 inches tall; it can increase to a total of 6 feet only if the extra height uses “see‑through” materials and the design is approved by the Planning Director (§ 17.05.080).

Q: Do mixed-use projects in the C-R district have special landscaping rules?

Yes. The C‑R district requires at least 10% of the lot landscaped, a 5‑ft landscaped buffer next to residential zones/alleys, a 5‑ft landscaped setback for street‑adjacent parking, street trees every 30 feet or less, and 1 tree per 7 parking spaces (§ 17.07.030; § 17.14.060(A)(4), (B)(2)).

Q: When is an 8-foot wall required between commercial/industrial and residential?

Nonresidential sites (commercial/manufacturing) that adjoin a residential zone, school, church, or park must construct and maintain an 8‑ft solid masonry wall on the side/rear property lines, with lower height where the wall aligns with the neighbor’s front setback (§ 17.06.080(A); § 17.09.070(A)).

Q: What are the corner visibility rules for fences and hedges?

Within the 40‑ft triangular sight area at street corners, no fence/hedge/wall or similar obstruction may exceed 40 inches in height to maintain visibility (§ 17.05.080; § 17.06.080(C)-(D); § 17.08.090(B)-(C)).

Q: Are there water-efficiency submittals for landscaping?

For all nonresidential projects and residential projects with 3+ units, you must submit a Landscape Documentation Package (landscape plan, irrigation plan, and post‑installation certificate) and meet hydrozone, irrigation, metering, and rain‑sensor criteria (§ 17.11.160(E)-(G)).

Q: Can I landscape the entire front yard in R-1 with hardscape?

No. In residential zones, front and street‑side yards must be landscaped and kept free of storage, with hardscape limited to 40% of the setback area for lots at least 60 ft wide or 50% for narrower lots (§ 17.05.070(A)-(B)).

Q: How must I screen parking that faces a public street?

Install a minimum 42‑inch high decorative block wall behind the required setback. In addition, use a 3‑ft high solid plant hedge to screen vehicles from street view where § 17.14.060 applies (§ 17.08.090(E); § 17.14.060(B)(3)).

Q: Are rooftop units required to be screened?

Yes. In the C‑R district, rooftop equipment must be screened from public view (§ 17.07.030, Table).

Q: Do manufacturing blocks have different fence height allowances?

Yes. On blocks entirely zoned C‑M or M and developed with permitted manufacturing, fences or walls up to 8 ft are allowed on sides/front/rear (behind required setbacks), and outdoor storage requires sight‑obscuring fencing (§ 17.08.090(D); § 17.09.070(B)).

Quick answer

Residential front fences are limited to 42 in solid, or up to 6 ft if the added height is see‑through and approved (§ 17.05.080). Parking lots must landscape at least 5% of the paved area with 6 in curbs and irrigation (§ 17.06.070; § 17.16.030). In the C‑R district, landscape 10% of the lot and provide a 5‑ft buffer at residential edges; street‑adjacent parking needs a 5‑ft landscaped setback (§ 17.07.030).

Overview

South El Monte’s zoning ordinance (Title 17) sets explicit citywide rules for landscaping, buffers, and screening in every zoning district. The code fixes minimum landscaped areas (especially for parking), prescribes fence/wall heights, requires screening where commercial or industrial sites abut homes, and adds water‑efficient landscaping submittals for larger projects. These requirements coordinate closely with parking, development standards, and some design review triggers.

Corner visibility is strictly protected: within the 40‑ft sight triangle at street corners, any fence/hedge/wall higher than 40 inches is prohibited to maintain safe sight lines (§ 17.05.080; § 17.06.080; § 17.08.090).

Citywide landscaping, buffers, and screening — what always applies

Parking areas: At least 5% of the total parking area must be landscaped; curbing must be at least 6 in concrete or 8 in masonry and an accepted irrigation system or hose bibs must be provided (§ 17.06.070; § 17.08.080; § 17.16.030(5)-(6); § 17.09.070).
Even distribution: The required 5% landscaping must be distributed “as evenly as possible” across the parking field; if not visible from the right‑of‑way, the City may shift it to front setbacks or other areas (§ 17.16.030(4)).
Fence/Wall height measurement: Height is measured at the highest finished grade within 3 ft of either side; up to 6 in of height variation is allowed to follow topography (§ 17.03.190).
Corner visibility: On corners, no obstructing fence/hedge/wall higher than 40 in within the 40‑ft sight triangle (§ 17.05.080(A)(2)-(3), (B)(2)-(3), (C)(2)-(3); § 17.06.080(C)-(D); § 17.08.090(B)-(C)).
Screening next to homes, schools, churches, parks (nonresidential sites): A solid 8‑ft masonry wall is required along shared side/rear property lines; along the adjacent residence’s front setback segment, the wall drops to 42 in (with a possible “see‑through” increase; see district notes below) (§ 17.06.080(A); § 17.09.070(A)).
Vehicles facing a street: A decorative block screen wall at least 42 in high is required behind the required setback when parking faces a public or private street (§ 17.08.090(E)).

Water-efficient landscaping (large residential and all nonresidential)

Applicability: All residential with 3+ units and all nonresidential must meet the water‑efficient landscaping criteria (§ 17.11.160(B)).
Submittal: A Landscape Documentation Package is required before permits, including a landscape design plan, irrigation design plan, and a certificate of substantial completion after installation (§ 17.11.160(E)).
Design criteria: Group plants by hydrozone, select climate‑appropriate species, use recirculating water for features, and design irrigation to avoid runoff/overspray; separate landscape meters are required except for single‑family or landscaped areas under 5,000 sq ft; rain sensors are required for landscaped areas 2,500 sq ft or more (§ 17.11.160(F)-(G)).
City discretion: The City may waive some requirements for limited like‑for‑like rehabilitation when irrigation is compliant and no ministerial permits are needed (§ 17.11.160(C)-(D)).

C-R corridor-specific requirements (Commercial-Residential district)

Minimum landscaping: At least 10% of the lot area must be landscaped (§ 17.07.030, Table 17.07.030‑A).
Street-adjacent parking: Must be set back at least 5 ft and that area must be fully landscaped (§ 17.07.030(C)).
Landscaped buffer at residential edges: A 5‑ft landscaped buffer is required on the subject property next to any residentially zoned property or intervening alley (unless the alley is providing direct vehicular access at that point) (§ 17.07.030(E)).
Screening and service: Rooftop equipment must be screened from public view; trash areas must be enclosed and screened, minimum 8 ft x 10 ft interior (§ 17.07.030, Table, “Rooftop Equipment” and “Trash Collection Areas”).
Streetscape and parking lot shading: Provide a tree canopy along street frontage with trees at intervals of 30 ft or less; in parking lots, provide 1 shade canopy tree per 7 spaces and include drought‑tolerant plantings and permanent water‑efficient irrigation (§ 17.14.060(A)(4), (B)(1)-(2)).
Ground-floor residential along street: Provide a landscaped setback of at least 3 ft to buffer units from the sidewalk (§ 17.14.060(A)(3)).
Screening of parked cars: Along streets, use a solid plant hedge maintained to at least 3 ft height to screen vehicles (§ 17.14.060(B)(3)).

Practical notes for applicants

If you provide any street setback in C‑R, the space can only be landscaping or active pedestrian uses—no parking spillover. Street‑adjacent parking must hold a 5‑ft landscaped edge (§ 17.07.030(C)).
For multifamily and all nonresidential, expect to submit a water‑efficient Landscape Documentation Package; plan early for hydrozones, separate meters (when required), and rain sensors for ≥2,500 sq ft landscaped areas (§ 17.11.160(E)-(G)).
Manufacturing or commercial sites next to homes will need a continuous 8‑ft masonry wall on the shared sides/rear, with reduced height where it aligns with a neighbor’s front setback (§ 17.06.080(A); § 17.09.070(A)).
The City measures fence height relative to the highest finished grade within 3 ft; detail your grade transitions to avoid inadvertent over‑height conditions (§ 17.03.190).
Projects in commercial/manufacturing zones that meet certain size/alteration thresholds must conform to City design guidelines—coordinate your landscape/screening early with design review triggers (§ 17.03.190(N)).

Checklist

Provide at least 5% landscaping within parking areas; distribute it evenly; use 6‑in concrete or 8‑in masonry curbing (§ 17.06.070; § 17.16.030(4)-(5); § 17.09.070).
Include an accepted irrigation system or hose bibs within 50 ft of all plantings (§ 17.06.070; § 17.08.080; § 17.16.030(6); § 17.09.070).
In C‑R, landscape at least 10% of the lot; provide a 5‑ft landscaped buffer next to residential or intervening alleys; setback street‑adjacent parking 5 ft and fully landscape it (§ 17.07.030(C), (E); Table 17.07.030‑A).
In parking lots, plant 1 tree per 7 spaces, use drought‑tolerant species, and install permanent water‑efficient irrigation (§ 17.14.060(B)(1)-(2)).
Along street edges of parking, maintain a 3‑ft solid plant hedge; where vehicles face streets, add a 42‑in decorative block wall behind the setback (§ 17.14.060(B)(3); § 17.08.090(E)).
Screen rooftop equipment from public view; enclose/screen trash with a decorative structure, 8' x 10' interior minimum where required in C‑R (§ 17.07.030).
At nonresidential edges adjoining homes, schools, churches, or parks, construct an 8‑ft masonry wall (apply reduced heights along the neighbor’s front setback as specified) (§ 17.06.080(A); § 17.09.070(A)).
Keep corner sight triangles clear above 40 in; verify fence/hedge layouts at corners (§ 17.05.080; § 17.06.080; § 17.08.090).
For residential 3+ units and all nonresidential, submit the Landscape Documentation Package and meet water‑efficient design/irrigation criteria (§ 17.11.160(E)-(G)).
In R‑1/R‑2/R‑3, landscape front and street‑side yards; stay within front‑yard hardscape caps (40% or 50% depending lot width) (§ 17.05.070).

Plain-English Summary

If you pave or park it, you must landscape it—at least 5% of parking areas with curbing and irrigation, and more in the C‑R corridors where 10% of the lot must be landscaped. Fences in front yards are capped at 42 inches unless the extra height is open “see‑through” and approved; industrial and commercial edges next to homes usually need an 8‑ft masonry wall. Corners stay low for visibility, and larger projects must submit a water‑efficient landscape package.

Frequently asked questions

What landscaping is required in South El Monte parking lots?

At least 5% of the total parking area must be landscaped, with planter curbs at least 6 inches (concrete) or 8 inches (masonry) and an accepted irrigation system or hose bibs within 50 feet. The 5% should be distributed as evenly as possible across the lot (§ 17.06.070; § 17.08.080; § 17.16.030(4)-(6); § 17.09.070).

How tall can a front yard fence be in South El Monte residential zones?

In R‑1, R‑2, and R‑3, a sight‑obscuring fence in the required front yard may be up to 42 inches tall; it can increase to a total of 6 feet only if the extra height uses “see‑through” materials and the design is approved by the Planning Director (§ 17.05.080).

Do mixed-use projects in the C-R district have special landscaping rules?

Yes. The C‑R district requires at least 10% of the lot landscaped, a 5‑ft landscaped buffer next to residential zones/alleys, a 5‑ft landscaped setback for street‑adjacent parking, street trees every 30 feet or less, and 1 tree per 7 parking spaces (§ 17.07.030; § 17.14.060(A)(4), (B)(2)).

When is an 8-foot wall required between commercial/industrial and residential?

Nonresidential sites (commercial/manufacturing) that adjoin a residential zone, school, church, or park must construct and maintain an 8‑ft solid masonry wall on the side/rear property lines, with lower height where the wall aligns with the neighbor’s front setback (§ 17.06.080(A); § 17.09.070(A)).

What are the corner visibility rules for fences and hedges?
