Trinidad — Landscaping and Screening

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

Last reviewed: July 6, 2026

Overview

Trinidad’s Landscaping and Screening rules live primarily in the citywide standards of Title 17 Zoning, especially the specific-use chapter for all zones. They control fence and hedge heights, when solid walls or dense planting are required, and how parking lots are buffered. They also interact with design review and coastal permit rules to protect public coastal views and sensitive areas.

Most proposals only need simple, durable plantings and code-checked fence heights — but if you’re near homes, a public view corridor, or the coast, expect added screening or view-sensitivity conditions per § 17.56.170 and § 17.60.050.

Citywide landscaping, screening, and fencing standards

Maintenance and materials
- All required planting must be kept in “good growing condition,” with replacement as needed; all screening must remain functional. Where trees are required, species/maturity/spacing must be acceptable to the Design Assistance Committee. For dense landscaping, pick evergreen types that form a year-round visual barrier. See § 17.56.170(A)–(B).
Required screening triggers
- Provide a dense landscape screen or a solid wall/fence at least 6 ft high:
  - Along rear and side property lines where any nonresidential use abuts a residential use.
  - Around open areas where goods, materials, or waste are stored (to screen from adjoining lots and public rights-of-way).
  - Around open areas displaying goods or materials for sale (to screen from abutting properties).
  - See § 17.56.170(C)–(D).
Parking lot edge landscaping and trees
- When 5+ off-street spaces are required, provide:
  - A perimeter landscape strip at least 4 ft wide between parking and the street right-of-way, protected by a curb/header.
  - One tree for the first five required spaces, plus one additional tree for every 10 more required spaces; plant trees in 4 ft by 4 ft curb-protected wells.
  - At least 2% of the parking area landscaped (including the perimeter strip).
  - See § 17.56.170(E) and cross‑check Trinidad Parking.
Fences, walls, and hedges — heights and safety
- Front and street-side yards: fences/hedges over 2.5 ft tall must be set back from driveway edges at least 15 ft; any fence in those yards cannot exceed 4 ft in height. See § 17.56.110(C).
- Interior side and rear yards: max height is 6 ft; taller allowed only with written consent from the adjoining owner and subject to emergency access. See § 17.56.110(D).
- Corner visibility triangle: within 20 ft of the street intersection line, sight‑obscuring fences, walls, and vegetation must not exceed 2.5 ft; tree branches must be clear to 8 ft. See § 17.56.110(F).
- Safety/security fences for public facilities are exempt from height limits. See § 17.56.110(G).
Parking next to homes
- Where a parking space or aisle abuts the UR or SR district, a sight‑obscuring fence at least 4 ft high is required at the interface. See § 17.56.180(C).
View‑sensitive planting and hardscape
- Landscaping of new development, and fences over 3 ft, must not significantly block views of the harbor, Little Trinidad Head, Trinidad Head, or the ocean from public roads, trails, and vista points. This standard is applied during design review; see § 17.60.050(B).
Permits and exemptions (landscaping/fences)
- Design review is generally not required for “changes in landscaping.” See § 17.60.030; still confirm any required coastal permit if in the Coastal Zone.
- Coastal Development Permit (CDP) exemptions include “fences up to 6 feet,” but not in the Special Environment (SE) zone. See § 17.72.070(C)(1)(a).

District-by-district notes (what matters for landscaping and screening)

Below are the zones used in Trinidad (Title 17). Purpose, typical uses, and the landscaping/screening angles that matter most for each district.

OS — Open Space

Purpose and where it applies: Protects natural/scenic character and cultural resources; applies to mapped open space areas. See § 17.16.010.
Typical permitted uses: Open space, wildlife habitat, low-intensity public recreation. See § 17.16.020.
Key dimensional standards: New dwellings not permitted; non-dwelling structures are tightly controlled and max height is 15 ft. See § 17.16.050–.070.
Landscaping/screening angle: Any vegetation disturbance may require a use permit, especially in the Tsurai study area; coordinated review for cultural resources is mandatory. See § 17.16.080.

SE — Special Environment

Purpose/where: Conserves coastal bluffs, tsunami/flood hazard areas, and other highly sensitive lands; extends seaward of mean high tide. See § 17.20.010.
Typical uses: Open space, low-intensity recreation; some uses via use permit. See § 17.20.020–.030.
Key dimensional/hazard standards: Bluff setbacks, slope limits, and stream-protection setbacks apply and limit vegetation removal. See § 17.20.080–.100.
Landscaping/screening angle:
- Fences on bluff tops must be “non-view‑obscuring.” See § 17.20.080(B).
- CDP exemptions for fences up to 6 ft do not apply here — expect a CDP in SE for fencing/landscape work. See § 17.72.070(C)(1)(a).

RP — Resource Production

Purpose/where: Preserves agricultural/forest lands and riparian habitats. See § 17.24.010.
Typical uses: Timber, agriculture; limited residential by use permit. See § 17.24.020–.030.
Key dimensional standards: Min. lot area 20 acres; yards 30 ft all sides; max height 25 ft. See § 17.24.040–.070.
Landscaping/screening angle: Vegetation removal within 100 ft of a perennial stream or in a public watershed needs findings to avoid erosion/habitat harm. See § 17.24.080.

SR — Suburban Residential

Purpose/where: Low-density residential areas; served or soon served by public water. See § 17.28.010.
Typical uses: Single-family homes; some ag/second unit by use permit. See § 17.28.020–.030.
Key dimensional standards: Front 30 ft, rear 20 ft, side 10 ft yards; max height 25 ft. See § 17.28.060–.070.
Landscaping/screening angle:
- Tree removal only when diseased/hazardous (city engineer approval). Limited removals allowed to improve views with DAC approval. See § 17.28.080.
- If a commercial parking lot abuts SR, a 4‑ft sight‑obscuring fence is required along the edge. See § 17.56.180(C).

UR — Urban Residential

Purpose/where: Highest-density single-family areas with public water; city’s core residential fabric. See § 17.32.010.
Typical uses: Single-family dwellings; guesthouses by use permit. See § 17.32.020–.030.
Key dimensional standards: Front 20 ft, rear 15 ft, side 5 ft yards; max height 25 ft. See § 17.32.060–.070.
Landscaping/screening angle: Same tree-removal limits as SR (diseased/hazardous only; limited removals to improve views with DAC approval). See § 17.32.080.

PD — Planned Development

Purpose/where: Flexible, integrated residential/limited commercial projects where design coherence is needed. See § 17.36.010.
Typical uses: Housing types in small clusters; limited visitor services/offices/retail by use permit. See § 17.36.020.
Key dimensional standards: Max height 25 ft; yards generally follow UR unless a 2,500‑sf minimum-lot pattern is approved. See § 17.36.050–.060.
Landscaping/screening angle:
- At least 25% of the site as common open space when dwellings are included; developer must landscape usable open spaces and arrange for perpetual maintenance; provide private open space per unit. See § 17.36.070.
- Development plan submittals must show “proposed landscaping, fencing and screening.” See § 17.36.080(A)(6) and maintenance program per § 17.36.080(C).

VS — Visitor Services

Purpose/where: Campgrounds/RV parks, motels, restaurants, and similar services near recreation/shopping with primary-collector access. See § 17.40.010.
Typical uses: Restaurants (except drive‑in), gift shops, motels/inns; campgrounds/RV parks by use permit. See § 17.40.020–.030.
Key dimensional standards: Yards 10 ft all sides; max height 25 ft. See § 17.40.060–.070.
Landscaping/screening angle: Trees should be retained “wherever feasible” in visitor accommodations. Nonresidential edges next to homes trigger the citywide 6‑ft screening rule. See § 17.40.080 and § 17.56.170(C).

C — Commercial

Purpose/uses/standards: Not found in retrieved materials.
Landscaping/screening angle: Citywide standards of § 17.56.170 apply (screening of storage/display; parking perimeter landscaping; adjoining‑residential buffers). Not found in retrieved materials for any additional C‑specific landscaping rules.

How it ties into view protection and permits

Landscaping and fences are part of Trinidad’s view‑protection framework. The Planning Commission ensures plantings and screens don’t disrupt public coastal views during design review under § 17.60.050(B).
Many simple “changes in landscaping” are exempt from design review, but projects in the Coastal Zone may still need a CDP; standard CDP exemptions for fences up to 6 ft do not apply in the SE zone. Check § 17.60.030 and § 17.72.070(C)(1)(a).
In the PD zone, landscape/open-space commitments are part of the use permit and must include long-term maintenance plans; see § 17.36.070–.080.

Checklist

Identify your zone (OS, SE, RP, SR, UR, PD, VS, or C) and any sensitive overlays/corridors that affect landscaping or views.
If nonresidential near residential, add a 6 ft solid fence/wall or dense landscaping along side/rear edges (§ 17.56.170(C)).
If 5+ parking spaces are required, show the 4 ft perimeter strip, tree count/tree wells, and 2% minimum landscaped area (§ 17.56.170(E)).
Place and size fences/hedges to meet height limits, driveway clearance, and corner visibility (§ 17.56.110).
Demonstrate that new landscaping/fences will not significantly block protected public views (§ 17.60.050(B)).
In SE or near streams/bluffs, confirm constraints and any CDP/design review triggers (§ 17.20.080–.100; § 17.72.070).
For PD projects, include landscape/open-space plans and maintenance provisions (§ 17.36.070–.080).
If removing trees for views or safety, obtain required approvals (SR/UR tree rules; DAC review) (§ 17.28.080; § 17.32.080).

Risks & Ambiguities

Issue	Why it matters	What to verify
View blockage by new hedges/trees	Can trigger design review denial or conditions	Provide sightline studies and confirm § 17.60.050(B) compliance with Planning staff.
Fence too tall in a yard	Violates § 17.56.110; appeal/abatement possible	Heights, driveway clearance, and corner triangle before installing.
SE zone coastal permits	CDP exemptions for fences don’t apply in SE	Ask if a CDP is required under § 17.72.070(C)(1)(a).
Nonresidential next to homes	6‑ft screening is mandatory	Add wall/dense hedge per § 17.56.170(C).
Parking landscaping shortfalls	Missing 4‑ft strip, tree wells, or 2% area causes resubmittal	Count trees/areas early; document per § 17.56.170(E).
Tree removal for views	Limited; DAC approval often required	Follow SR/UR tree rules in § 17.28.080 / § 17.32.080.
Rare plants	State coordination can add mitigation	If north of Main St., check § 17.56.140.

Plain-English Summary

If you’re adding plants, putting in a fence, or designing a parking lot in Trinidad, keep fences short in front yards, buffer parking with a 4‑ft landscape strip and trees, and use a 6‑ft wall or dense hedge where businesses meet homes. In scenic or coastal‑sensitive areas, new landscaping and fences must preserve key public views, and work in the Special Environment zone may also need a coastal permit.

Frequently asked questions

Do I need design review to change plants or install a fence?

Simple changes in landscaping are generally exempt from design review, but work in the Coastal Zone may still need a Coastal Development Permit. Fences up to 6 ft are often CDP‑exempt, except in the Special Environment zone, where a CDP can still be required (§ 17.60.030; § 17.72.070(C)(1)(a)).

How tall can my front-yard fence or hedge be in Trinidad?

In required front or street-side yards, fences/hedges are limited to 4 ft. Also keep taller sight‑obscuring elements at least 15 ft from the driveway edge at the property line, and preserve corner visibility within 20 ft of intersections (§ 17.56.110(C), (F)).

What landscaping must I put around parking?

If you need 5 or more spaces, provide a 4‑ft landscape strip along the street edge, tree wells 4 ft by 4 ft, one tree for the first five spaces plus one per 10 additional spaces, and landscape at least 2% of the parking area (§ 17.56.170(E)).

I’m proposing a motel/restaurant next to homes. What screening is required?

Nonresidential uses abutting residential must screen side and rear edges with a solid 6‑ft fence/wall or dense evergreen landscaping. Storage and outdoor display areas must also be screened from neighbors and public rights‑of‑way (§ 17.56.170(C)).

Can I remove trees to improve my ocean view?

Only limited removals are allowed, and many require Design Assistance Committee approval. In SR and UR, hazardous/diseased removals are allowed (with city engineer approval), and minimal removals may be approved to improve views; public view protection standards also apply (§ 17.28.080; § 17.32.080; § 17.60.050(B)).

Do ADUs trigger any screening rules?

Yes. To protect neighbor privacy, windows facing adjacent residences must be designed to reduce overlook, or “fencing or landscaping shall be required to provide screening” (§ 17.54.070(J)).

Are there special landscaping rules near streams or bluffs?

Yes. In SE and related sensitive areas, vegetation disturbance is tightly limited; stream protection requires 100‑ft buffers with strict conditions, and bluff‑top fences must be non‑view‑obscuring (§ 17.20.080–.100).

In PD projects, what landscaping commitments are required?

When housing is included, at least 25% of the site must be common open space; usable areas must be landscaped with ongoing maintenance arrangements. Submittals must show proposed landscaping, fencing, and screening (§ 17.36.070–.080).
