Fowler — Landscaping and Screening

Q: Are there special planting or buffer requirements for properties along Highway 99?

Yes — the HB Overlay requires landscape buffers adjacent to Highway 99: for most residential next to at‑grade highway the buffer is 20 ft with 1 tree per 25 ft of frontage; different rules apply for elevated segments and for heavy/unsightly uses (see § 9‑5.1907)

Overview

This page summarizes what the Fowler Zoning Ordinance requires for landscaping, screening, buffers, fences, walls, and trees. It interprets the zoning rules you must follow when you design sites, parking lots, yards, or facilities adjacent to other districts (especially residential areas and Highway 99). For a high-level orientation to the city's rules and where landscaping fits in the permitting flow, see the Fowler zoning & planning overview. The guidance below is limited to what the Fowler zoning/planning ordinance says — building-code and state ADU rules are out of scope here.

How this page is sourced

All requirements summarized below are taken from the Fowler Zoning Ordinance (citations show the controlling §). Where I refer to ordinance text, I cite the exact code section(s) and the file preview returned by the user's upload for verification (e.g., § 9‑5.21.12 ). Verify details with the City when a parcel-specific rule may apply.

District-by-district breakdown (landscape & screening focus)

Note: the ordinance applies Article 21 (landscaping/site standards) across districts; many district-specific subsections then add special screening/fence/buffer rules. Below I list the districts that include explicit landscaping/screening provisions in the ordinance, with the code references and practical implications.

R-1 (Single‑Family Residential) — R-1

Purpose & typical uses: single‑family homes, accessory structures; design emphasis on front-yard landscaping and neighborhood character. See the single-family design criteria and residential district rules. (§ 9‑5.21.* and related design criteria)
Landscaping & planting: All required yards must be landscaped unless occupied by walkway/driveway or screened behind a ≥6 ft fence (§ 9‑5.21.08–.12). Front/corner yards must include medium trees at about 1 per 30 ft of frontage where landscaping is required (§ 9‑5.21.08/§ 9‑5.21.12)
Fences/walls: Height limits and transparency requirements for fences in front/corner/side yards: typical front/corner fences limited to 42 inches and at least 50% open; side/rear fences up to 6 ft except front-yard limits (§ 9‑5.21.09)
Where it applies: citywide to lots zoned R-1 and similar R districts; additional subdivision design criteria require front-yard landscaping before occupancy (§ 9‑5.1714 / single‑family design criteria)

RM (Multi‑Family Residential) — RM

Purpose & typical uses: multi-family dwellings; accessory uses (pools, parking) per RM district rules (§ 9‑5.801–.804). Landscaping requirements defer to Article 21 and site‑plan review for larger projects.
Screening & yards: Where RM adjoins lower‑density zones the code requires transitions (walls, landscaping, setbacks) as part of subdivision/site‑plan approvals (see buffer/transition language in the design criteria and PUD provisions) (§ 9‑5.1714; § 9‑5.28.05.D)
Where it applies: multi‑family parcels; landscape and screening typically reviewed under site plan/design review (Article 16/26)

C-1 (Neighborhood Commercial) — C-1

Purpose & typical uses: small retail and neighborhood services adjacent to residential blocks (§ 9‑5.1001–.1003).
Required landscaping & screening:
- When a C-1 site adjoins or is across the street/alley from any residential district, a decorative masonry wall minimum 6 ft high (or other screening as required) must be placed on the property line common to the districts, except in required front yards (§ 9‑5.1006.A)
- Where C‑1 sites are in the same block as residential lots, the front yard minimums increase and at least 10 ft of front yard must be landscaped (§ 9‑5.1012)
Where it applies: all C‑1 parcels; commercial projects are subject to design review (Article 16) and site plan approval (§ 9‑5.1019)

C-2 / C-3 (Community / General Commercial) — C-2, C-3

Purpose & typical uses: larger retail, services, offices, and community serving uses (§ 9‑5.1101 et seq.; § 9‑5.120* series).
Screening & landscaping:
- Where a site adjoins or is across from a residential district, a decorative masonry wall minimum 6 ft high or similar screening is required on the property line (see the C‑2/C‑3 screening sections: § 9‑5.1106 / § 9‑5.1206 — the ordinance repeats this standard for commercial districts)
- Open storage must be enclosed/screened with a solid wall/fence 6 ft minimum and not visible above the fence, unless Site Plan Review modifies that (§ 9‑5.1006.B; § 9‑5.1206.B)
Where it applies: community and general commercial zones; site plan review and design review apply for commercial development and parking lot screening (see Fowler Parking for parking screening expectations)

M-1 (Light Industrial) and M-2 (Heavy Industrial) — M-1, M-2

Purpose & typical uses: light industrial and heavier industrial activities; uses that might generate noise/visual impacts are regulated with additional screening requirements (§ 9‑5.1504 / 9‑5.1404 series).
Screening & walls:
- When an industrial site adjoins a non‑industrial district, a solid wall or screen fence 6 ft in height (or other Director‑required screening) shall be located on the common property line, except in required front yards (§ 9‑5.1406 / § 9‑5.1506)
- Uses not conducted fully inside a structure and sites across a street from non‑industrial districts may be required to be screened by a decorative masonry wall 6 ft high if the Director finds them unsightly (§ 9‑5.1406.B)
- Barbed/razor wire allowed only in M‑1/M‑2/RCO with Administrative Approval; electrified fences prohibited except where Civil Code requires them (§ 9‑5.21.09.D)
Where it applies: industrial zones citywide; detailed yard/buffer requirements for specific industrial uses are provided elsewhere in Article 19/related sections referenced below.

HB — Highway Beautification Overlay — HB Overlay

Purpose & where it applies: promotes attractive development along Highway 99; applies to properties within 1,000 ft of the Highway 99 right‑of‑way (§ 9‑5.1901–.1902)
Overlay landscaping & buffer standards (common, decision‑critical rules):
- Residential next to at‑grade highway: 20 ft landscaped buffer; trees at 1 per 25 ft of highway frontage; groundcover/shrubs and restrictions on uses inside the buffer (no buildings, parking, trash, freestanding signs, towers) (§ 9‑5.1907.E.6.a–i)
- Residential next to elevated highway: 10 ft landscaped buffer; trees at 1 per 25 ft (§ 9‑5.1907.E.6.b)
- Wrecking yards/auto storage/recycling next to at‑grade highway: 20 ft landscaped buffer with continuous shrub hedge plus trees (shrubs attains ≥8 ft; trees 20 ft on center); 6 ft masonry wall at rear of buffer located 20 ft from property line (§ 9‑5.1907.E.7.a–d)
- Commercial & most non‑industrial uses: 20 ft landscaped setback along at‑grade highway; 1 tree per 25 ft (§ 9‑5.1907.E.8.a)
Practical effect: the HB overlay creates fixed landscape setbacks/planting rates and mandatory walls for certain heavy/unsightly uses — these overlay rules override or add to the underlying zone standards within the overlay boundary. See Fowler Overlay Districts for map/where it applies.

Checklist — what an applicant must satisfy for landscaping/screening

Provide a landscape plan prepared by a licensed landscape contractor or landscape architect where required (HB overlay buffers, subdivision/site plan, and whenever the ordinance imposes landscaping) (§ 9‑5.1907.E.3)
Demonstrate required plant types, spacing and tree counts (for HB overlay: 1 tree per 25 ft for highway frontage; residential front yard tree spacing) (§ 9‑5.1907.E.6–8; § 9‑5.21.12)
Show required walls/fences on the plan where site adjoins residential or non‑industrial districts (6 ft masonry or other Director‑required screening) (§ 9‑5.1006; § 9‑5.1406; § 9‑5.1506)
For parking lots, include shading calculations and tree canopy schedule where parking‑shading standards apply; show screening from rights‑of‑way as required (Article 20 and site plan requirements) (§ 9‑5.21.13 / Article 20 references)
If proposing variances (e.g., fence height >6 ft in side/rear), prepare findings addressing practical difficulty and neighborhood impact (variance standards) (§ 9‑5.27.04)
If the site is inside the HB overlay, show the buffer easement/dedication and maintenance mechanism (e.g., LLD, HOA, contract), and indicate whether a masonry wall is provided for certain uses (§ 9‑5.1907.E.3–4)
Expect site plan review and possible design review; show mechanical/equipment screening consistent with Single‑Family Design Criteria and Site Plan Review (Article 16 / Article 26) — see Fowler Design Review and Fowler Development Standards for process links.

Risks & Ambiguities

Issue	Why it matters	What to verify
Landscaping species / irrigation requirements	Ordinance mandates planting and tree counts but does not specify exact species or irrigation methods in the excerpts	Verify species lists, water budgets, local plant palettes, and any separate street‑tree lists or standards (not found in the retrieved materials). (§ 9‑5.21.12 mentions standards generally)
Location of required masonry walls in HB overlay (setback vs. property line)	The HB text requires a masonry wall "at the rear of the landscaped buffer" and located 20 ft from the buffered property/right‑of‑way line for certain uses — conflicting references to exact placement can affect easements and ROW encroachment	Confirm required wall location and whether the wall sits on private property or within a dedicated easement; verify with the City (see § 9‑5.1907.E.7.c)
Which district section controls (C‑1 vs. C‑2 vs. C‑3 variations)	The ordinance repeats similar screening language across commercial district sections but details (front-yard landscaping requirements, yard depths) vary by district and block context	Verify the underlying district of the parcel and read the matching district § (e.g., § 9‑5.1006 for C‑1, § 9‑5.1106 for C‑2, § 9‑5.1206 for other commercial)
Applicability to existing nonconforming fences/walls	The code treats nonconforming fences/walls differently (some nonconforming fences excluded from relief)	Check nonconforming provisions and whether replacement or alteration triggers compliance; see nonconforming and variance provisions (not fully specified for every situation) (§ 9‑5.1404 and Article 27 mention nonconforming fences)
Planting/maintenance obligations for buffers in public easements	HB overlay suggests buffers may be placed in easements and dedicated to the City, with maintenance by LLD/HOA — this affects long‑term maintenance costs and responsibility	Confirm the required dedication/maintenance mechanism for the specific project and whether City acceptance is required (§ 9‑5.1907.E.4)

Plain‑English Summary

Fowler requires landscaped yards, trees, and screening walls in many zones; most importantly, where non‑industrial and industrial or commercial sites touch residential districts the code generally requires a decorative masonry or solid screen wall 6 ft high and landscaped buffers in Highway Beautification areas (20 ft with tree spacing requirements). Site plans and design review almost always trigger landscape plan review; verify the parcel’s underlying zone and whether the Highway Beautification Overlay applies. Key ordinance references include explicit fence heights (front ≤42 in; side/rear ≤6 ft) and the HB overlay buffer rules (§ 9‑5.21.09; § 9‑5.21.12; § 9‑5.1907) .

Information Gaps

Exact plant species lists, irrigation, and low‑water palette guidance: Not found in retrieved materials (verify with Public Works / Planning or a separate landscape standard manual).
Detailed parking-lot shading design standards (numeric shading targets are referenced but the full calculation methodology and thresholds are in Article 20 and site plan detail): partially referenced; full numeric procedures not found in the snippets. (§ 9‑5.21.* and Article 20 references)
Street tree species lists and planting standards for municipal acceptance: Not found in retrieved materials; see City street‑tree policy or Public Works standards.
Precise map of the HB Overlay boundaries: the ordinance says "within 1,000 ft of Highway 99", but parcel‑specific extent and map layers should be confirmed on city planning maps (see Fowler Overlay Districts). (§ 9‑5.1902)

Frequently asked questions

Do I need a landscape plan for a small commercial remodel in Fowler?

If the ordinance requires landscaping for the yard or you are inside the HB Overlay, you must submit a landscape plan prepared by a licensed landscape contractor or landscape architect; site plan or design review may also require it (§ 9‑5.1907.E.3; § 9‑5.28.05.D)

When is a masonry wall required between my industrial lot and a neighboring residential lot?

Where an industrial site adjoins any non‑industrial (including residential) district, the code generally requires a solid wall or screen fence 6 ft in height on the common property line, except in required front yards (Director can modify type/height) (§ 9‑5.1406; § 9‑5.1506)

What fence heights are allowed in a residential front yard?

Residential front and corner yard fences must generally be no taller than 42 inches and must be at least 50% open; side/rear yard fences can be up to 6 ft high (§ 9‑5.21.09.A)

Are there special planting or buffer requirements for properties along Highway 99?

Yes — the HB Overlay requires landscape buffers adjacent to Highway 99: for most residential next to at‑grade highway the buffer is 20 ft with 1 tree per 25 ft of frontage; different rules apply for elevated segments and for heavy/unsightly uses (see § 9‑5.1907)

Can I put parking within the highway buffer in the HB Overlay?

Parking may be allowed within the 20‑ft setback only in limited cases and typically subject to site plan review; the overlay text specifically prohibits many structures and requires that noise/screening standards are met (§ 9‑5.1907.E.6.a.ii–iii; § 9‑5.1907.E.7.d)

Can I use barbed‑wire or electrified fencing on a commercial lot in Fowler?

Barbed or razor wire is generally prohibited citywide but may be allowed in M‑1, M‑2, or RCO zones with Administrative Approval; commercial zones may seek it via CUP — electrified security fencing is prohibited except as Civil Code or a law enforcement agency requires (§ 9‑5.21.09.D)

If my project spans a commercial and residential block, who decides the screening type?

Screening type and height are controlled by the district rules and by Site Plan Review or the Director; if the Director finds a use "unsightly" additional masonry screening may be required. Large or controversial proposals may be elevated to the Planning Commission (§ 9‑5.1006; Article 26)

Does Fowler require street trees for new development?

Yes — when front or corner lot yards are required to be landscaped, medium trees are required at intervals (typically 1 per 30 ft of frontage in residential contexts) and street trees/other landscaping may be required under Articles 21 and 26; exact street‑tree species lists are not included in the ordinance text retrieved here (§ 9‑5.21.12; § 9‑5.1006.C)

Who maintains buffers placed in an easement or dedicated to the City?

The ordinance contemplates buffers placed in easements and dedicated to the City with maintenance by a landscape & lighting district, HOA, or property management company; the project must show a maintenance mechanism on plan submittal (§ 9‑5.1907.E.4)
