Ross — Landscaping and Screening
Landscaping and Screening under the Ross local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
This page summarizes what the Town of Ross zoning ordinance requires for landscaping and screening (trees, fences, walls, planting, and visual/utility screening) under the town’s Title 18 Zoning rules. It focuses only on landscaping and screening rules in the Ross zoning ordinance (design review triggers, fence/wall height limits, landscape design guidance, and special standards for utility/tower sites). For permit triggers and exceptions see the town’s rules on design review, development standards, and zoning. For interaction with construction/building standards, consult the California Building Standards Code (Title 24).
How this page is grounded
Every requirement below is tied to a Ross Municipal Code provision and cited with the controlling § number; the uploaded Ross ordinance excerpts used to prepare this page are cited inline. If a topic could not be located in the retrieved materials I note "Not found in retrieved materials" and advise to verify with the Town.
District-by-district breakdown
Notes: Ross’ ordinance contains both district-specific permitted uses (for example the R-1 single-family district) and townwide / chapter-level rules that apply across districts. Where a rule is townwide I list it under All districts (general standards).
All districts (general standards)
Purpose and where it applies:
- Townwide design, protection of natural features, erosion control, and screening guidance appear in the design review and general regulations chapters; these are applied to projects across zones through the design review process and the general rules in Chapter 18.40 and Chapter 18.41. See § 18.41.100 and § 18.40.020.
Key landscaping & screening elements:
- Design review triggers: landscaping-related work can trigger formal review. Design review is required for projects including: >1,000 sq ft of new impervious landscape surface; redevelopment/renovation of existing landscaping over 2,500 sq ft; and other site-disturbing activities. See § 18.41.020(a)(11)–(12).
- Landscape guidance: native shrubs/trees should be preserved where possible; drought- and fire‑resistant plantings are recommended; new hillside landscaping requires an irrigation system; landscaping should preserve sunlight to neighbors and soften or screen structures and equipment. See § 18.41.100(e) and related design criteria.
- Erosion and drainage: landscaping plans must address erosion and stormwater (low-impact development techniques), and disturbed slopes must be replanted or stabilized within 30 days. See § 18.41.100(a) and related grading rules.
Practical effect:
- Even small landscape plans may be subject to review if they add impervious surface, change drainage, or exceed the numeric thresholds above. See § 18.41.020.
Single‑Family Residence — R-1
Purpose and where it applies:
- The R-1 district preserves low-density single-family character; landscaping rules for R-1 properties are implemented through the R-1 chapter plus the townwide design review criteria. See § 18.16.010–018.
Typical permitted uses (landscape & screening-related):
- Screening walls, fences, driveways, walkways and similar accessory landscape structures are explicitly listed among permitted accessory uses in R-1 (subject to requirements). See § 18.16.030(a).
Key dimensional/approval standards that affect landscaping:
- Fences/walls: front yard fences generally limited to 4 ft, side/rear yard fences 6 ft (measurement rules apply); front-yard fence up to 6 ft allowed with design review; sports court/backstop fences up to 10 ft with design review. See § 18.40.080(a)(1)–(5).
- Design review for fences/walls: fences, gates or walls greater than 48 inches in any yard adjacent to a street or right-of-way require design review under § 18.41.020(4). See § 18.41.020(4).
- Minor exceptions: a fence up to 7 ft in side/rear yards may be permitted via a minor exception (Chapter 18.45). See § 18.40.080(a)(1) and § 18.45 (minor exceptions).
Practical effect:
- Homeowners in R-1 proposing new fences, retaining walls, or large landscaping changes should expect either administrative design review or Town Council review depending on height, location, and degree of site disturbance. See §§ 18.41.020 and 18.41.060–070.
Utility / Telecommunications sites and accessory equipment (Chapter 18.55)
Purpose and where it applies:
- Chapter 18.55 governs wireless telecommunications and sets specific screening, camouflaging, and landscaping expectations where equipment is above ground or visible. These standards apply to facilities inside and outside the right-of-way and to accessory equipment footprints. See § 18.55.080–100.
Key screening & landscaping elements:
- Screening of accessory equipment: above-ground accessory equipment must be enclosed, not exceed five feet in height for small cabinets, and must be screened/camouflaged "to the fullest extent possible," including with landscaping. See § 18.55.100(H).
- Setback from curb: equipment, mounting, or screening shall be setback a minimum of 18 inches from curb face when mounted to walls, fences or landscaping. See § 18.55.100(D)(3).
Practical effect:
- Telecom or utility projects should plan integrated landscape screening in the permit submittal; the Town may require bonds to guarantee landscape/maintenance obligations. See § 18.55.100(A)(8).
Key standards and decision‑relevant table
| Topic | Decision‑relevant standard / limit | Code Reference |
|---|---|---|
| Front yard fence height (residential) | 4 ft standard; up to 6 ft allowed with design review | § 18.40.080(a)(2) |
| Side/rear yard fence height | 6 ft max (minor exception to 7 ft possible) | § 18.40.080(a)(1) & 18.45 (exceptions) |
| Design review trigger — landscaping | > 1,000 sq ft new impervious landscape; landscaping redevelopment >2,500 sq ft | § 18.41.020(a)(11)–(12) |
| Fences/walls subject to design review | Fences/gates/walls > 48 in in any yard adjacent to street/right-of-way | § 18.41.020(4) |
| Irrigation for new hillside landscaping | Irrigation system required for new hillside landscaping | § 18.41.100(e)(4) |
| Screening for telecom accessory cabinets | Cabinets up to 5 ft must be screened/camouflaged; undergrounding preferred | § 18.55.100(H), § 18.55.100(D) |
| R-1 permitted accessory landscape uses | Screening walls, fences, terraces, arbors, etc., permitted subject to requirements | § 18.16.030(a) |
Practical guidance / interpretation (plain‑English synthesis)
- If your landscape work adds hardscape, impervious area, or modifies drainage, check the design review triggers in § 18.41.020; projects that add >1,000 sq ft impervious landscape or alter >2,500 sq ft of landscape typically require review.
- Fences facing the street are tightly regulated: the default is 4 ft; if you want more than 48 in (4 ft) where that fence is adjacent to a street you must either get design review or pursue a minor exception/variance as described in §§ 18.41.020 and 18.45.
- Landscapes on hillsides must retain native trees where feasible, include irrigation for new plantings, and protect against erosion and stormwater impacts. Be prepared to show how the plan preserves sunlight to neighbors and provides defensible space for fire safety. See § 18.41.100 and related grading/erosion provisions.
- For utilities or telecom equipment, the code expects camouflage and landscaping as part of approval and allows bonds to guarantee maintenance of screening. See § 18.55.100.
Checklist
- Confirm whether your proposed work triggers design review: check § 18.41.020 ( >1,000 sq ft impervious, >2,500 sq ft landscaping redevelopment, any fence/wall >48 in in street yard).
- For fences/walls: measure height from existing grade; verify front vs side/rear limits (4 ft / 6 ft) and whether design review or minor exception is needed (§ 18.40.080).
- Prepare landscape plan that addresses erosion control, stormwater (LID), irrigation for new hillside planting, and tree protection (§ 18.41.100).
- If installing mechanical equipment or telecom cabinets, include screening/camouflage details and consider undergrounding as preferred (§ 18.55.100).
- If proposing retaining walls, calculate cumulative height limits and terracing spacing (see Chapter guidance on retaining walls and grading). Noted in design criteria — verify with Town.
- If the proposal involves tree removal, confirm local tree protection/permit requirements (verify with the Town — Not found in retrieved materials).
- If requesting an exception (fence over standard height or other deviation), prepare findings and follow Chapter 18.45 procedures.
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Fence height measured from sloped grade | Height is measured from existing grade; artificially raising grade to circumvent limits is controlled | Verify how the Town will measure height on your lot and whether grading affects allowed height; see § 18.40.080(c). |
| Tree removal/heritage tree rules | Trees are protected in policy text, but specific tree‑removal permit rules or heritage lists were not found in retrieved excerpts | Verify the Town’s tree ordinance or planning department requirements (Not found in retrieved materials). |
| Fire defensible space vs. screening (privacy hedges) | Fire safety rules (defensible space) can conflict with dense screening plantings | Confirm applicable fire clearance and PRC 4291 compliance and how the Town balances defensible‑space rules with screening needs; see design review and public safety guidance. |
| Landscaping thresholds that trigger review | Numeric thresholds (1,000 sq ft, 2,500 sq ft) can be counted differently (impervious vs. softscape) | Verify how the Town measures “impervious landscape surface” and whether certain permeable pavers are counted; see § 18.41.020(a)(11)–(12). |
| Retaining wall cumulative heights | Terraced wall spacing and cumulative heights limit design and plantability | Check the retaining wall maximums and terracing spacing in the grading/standards chapter before planting plans are finalized. See retaining wall language and terracing guidance. |
| Telecom/utility screening maintenance | Town can require bonds and ongoing maintenance conditions tied to approval | Confirm bond and maintenance conditions in approvals for utility/telecom sites (§ 18.55.100). |
Plain‑English summary
Ross’ zoning code generally favors preserving native trees and natural landscape, requires irrigation for new hillside planting, limits fence and wall heights (typically 4 ft front, 6 ft side/rear), and triggers design review for larger landscape projects (notably >1,000 sq ft new impervious landscape or >2,500 sq ft landscape redevelopment). Always check whether your project triggers design review or a minor exception; for utility or telecom equipment the town expects camouflage and maintained plant screening. See §§ 18.40.080, 18.41.020, 18.41.100, and 18.55.100.

Frequently asked questions
Do I need design review for planting a privacy hedge between my house and the street in Ross?
Short answer: Possibly. Design review is required for fences, gates or walls greater than 48 inches in any yard adjacent to a street or right‑of‑way (§ 18.41.020(4)). If your hedge is intended to function as a fence/wall in that location or you propose associated hardscape that crosses numeric thresholds (for example adding >1,000 sq ft of new impervious landscape or redeveloping >2,500 sq ft of landscaping), design review can be required (§ 18.41.020(a)(11)–(12)).
What are the standard fence height limits in Ross?
Standard maximums are 4 ft for front‑yard fences and 6 ft for side/rear yards. A front‑yard fence up to 6 ft may be permitted with design review, and a side/rear fence up to 7 ft can sometimes be allowed via a minor exception (§ 18.40.080; Chapter 18.45 for exceptions). Check how height is measured from existing grade (§ 18.40.080(c)).
Does Ross require irrigation for new plantings on slopes or hillsides?
Yes — the design guidance calls for an irrigation system to establish new hillside landscaping and preservation of native shrubs/trees where feasible; landscape plans should also address erosion control and slope stabilization (§ 18.41.100(e) and associated grading rules).
Will installing mechanical equipment (AC condenser, telecom cabinet) require screening with landscaping?
Likely. For wireless and many above‑ground accessory equipment types the Code requires equipment to be enclosed or screened and camouflaged “to the fullest extent possible,” and landscaping may be required as part of that screening; the Town prefers undergrounding where feasible (§ 18.55.100(H) and § 18.55.100(D)).
When does a landscaping project trigger formal design review in Ross?
Design review is triggered for a number of thresholds, notably projects creating >1,000 sq ft of new impervious landscape surface and redevelopment/renovation of existing landscaping over 2,500 sq ft; other triggers include fences >48 in adjacent to streets and greater grading or creek‑setback work (§ 18.41.020(a)(11)–(12) and § 18.41.020(4)).
Are there special rules for retaining walls and terraced walls related to landscaping?
Yes. Retaining walls and terraced walls have height and spacing guidance: individual retaining walls should generally not exceed certain heights, terraced walls should allow space for screening vegetation, and cumulative heights are limited — check the retaining‑wall and grading provisions in the code and design guidance (§ 18.41.100 and related grading language). Verify specific numeric limits with the Town for your site.
Do I need a permit to remove a tree in Ross for landscaping?
Not found in retrieved materials: the uploaded ordinance excerpts stress protecting trees and replacing removed trees where possible but do not include a standalone tree‑removal permit procedure in the excerpts provided. Verify tree‑removal or heritage‑tree rules with the Town of Ross planning staff (Not found in retrieved materials).
Can I use a living fence (dense hedge) to create privacy even if it conflicts with defensible‑space rules?
You must balance privacy plantings with fire‑safety/defensible‑space obligations. The code and design guidance require defensible spaces and fuel‑reduction clearances consistent with California laws; confirm acceptable species and placement with the Town and fire authority if your hedge would encroach into required defensible space (see design guidance and public‑safety subsections — verify with Town).
