Overview

This page explains how landscaping and screening are regulated in the unincorporated areas of Calaveras County under Title 17 (Zoning). The County’s core landscaping rules live in Chapter 17.20 and are reinforced by general site regulations, zone-specific standards, and special-use standards. Where a project falls in a mapped overlay or a design review area, additional scrutiny applies.

Most projects must landscape the visible street edge and screen equipment: in unincorporated areas, multifamily fronts, commercial frontages, and certain industrial frontages require landscaping, and anything placed in a front setback that’s noisy or bulky (like HVAC or propane) must be screened with plants or a solid fence per § 17.16.080.

Countywide landscaping framework (applies in all zones)

  • Purpose and applicability. The County’s landscaping chapter promotes attractive development, water conservation, erosion control, and long-term maintenance; it applies to “all landscape projects” in unincorporated Calaveras County per § 17.20.010–.020.
  • Water efficiency baseline. All landscaping must meet California’s Model Water Efficient Landscape Ordinance and CALGreen irrigation provisions per § 17.20.030. This is a zoning mandate that points you to state rules; see also our primer on the California Building Standards Code.
  • What “landscaping” means. The Code defines landscaping broadly to include trees, shrubs, groundcover, decorative walls/fences/trellises, and similar features serving aesthetic or functional purposes per § 17.43.120.

Where the Code requires landscaping or screening

  • R2/R3 multifamily frontage. In the R-2 and R-3 zones, all required front and street-side setbacks (except driveways/walks) must be landscaped per § 17.20.040(A).
  • Commercial frontage. In all Commercial zones (HC, C-1, C-2, CP), landscape the area between the front building plane and the public right-of-way, except where used for exits/entries, parking, or similar improvements per § 17.20.040(B). See also Calaveras County Zoning.
  • M4 industrial frontage. In M-4 Industrial, the same building-to-street landscaping strip is required per § 17.20.040(C).
  • Parking areas. Parking lots must be landscaped as required by the County’s parking chapter; § 17.20.040(D) cross-references Chapter 17.22. Details on planter dimensions/trees were not found in retrieved materials; confirm with the Planning Department.
  • Disturbed areas. Any vegetation disturbed by construction must be replaced with native or drought-tolerant landscaping per § 17.20.040(E).
  • Screening in setbacks. Mechanical equipment and propane tanks in a required front setback must be screened with landscaping or a solid fence per § 17.16.080(A)(1)(f)–(g). Additionally, fences/walls and landscaping are allowed encroachments into setback areas per § 17.16.080(A)(1)(c)–(d).
  • Stream/wetland setbacks and fencing. Within required stream/wetland buffers, only limited activities are allowed; fencing there must not impede water flow or wildlife corridors per § 17.16.080(B)(2)(b).
  • Design Review areas. In the DR Overlay, the County may condition landscape design, plant selection/size, fences, walls, and “screen plantings” through § 17.29.050 and the mapped applicability in § 17.11.020; see Calaveras County Design Review.
  • Mobile home parks. All open areas must be landscaped; the Planning Commission may require street trees; any on-site storage areas must be screened from public view per § 17.25.150(H) and (M).
  • Wireless facilities. Telecommunication facilities must be “located, designed and screened” to blend in; equipment cabinets and ground gear must be screened by walls and/or landscaping, and any security fencing must be screened and may not be visible chain link. These standards sit in § 17.25.210 (Telecommunication Facilities); see performance language at § 17.25.210(5)–(6).

District-by-district: what landscaping/screening means where

Below, “key dimensional standards” help you judge frontage widths and setbacks where landscaping must fit. For broader context see the Calaveras County Development Standards and Calaveras County Land Use.

R-2 (Two-Family Residential)

  • Purpose/uses. Duplex-scale residential neighborhoods; allows attached units and multifamily per Table 17.05.020.
  • Key standards. Max density 12 du/ac, max height 35 ft; front/side/rear setbacks per Table 17.05.030.
  • Landscaping/screening trigger. Landscape all required front and street-side setbacks (except entries/driveways) per § 17.20.040(A).
  • Where it applies. Unincorporated parcels zoned R-2.

R-3 (Multiple-Family Residential)

  • Purpose/uses. Multifamily neighborhoods; larger buildings and higher density than R-2; allowed residential types per Table 17.05.020.
  • Key standards. Max density 20 du/ac, max height 45 ft; setbacks as in Table 17.05.030.
  • Landscaping/screening trigger. Same as R-2: landscape required front and street-side setbacks per § 17.20.040(A).

  • If in R-2/R-3, design landscaping for all required front and street-side setbacks per § 17.20.040(A).
  • If in Commercial or M-4, landscape the building-to-right-of-way strip per § 17.20.040(B)/(C).
  • Place and screen any equipment in front setbacks with plants or a solid fence per § 17.16.080.
  • Make your landscape plan MWELO-compliant per § 17.20.030 (water budgeting/irrigation).
  • If you have a parking lot, add required planters/trees per Chapter 17.22 (verify specifics).
  • If in the DR Overlay, coordinate early with staff on plant palettes, walls, fences, and screening per § 17.29.050 and § 17.11.020.
  • For telecom, design stealth/screening per § 17.25.210 (no visible chain link).

Risks & Ambiguities

Issue Why it matters What to verify
Parking-lot landscape details § 17.20.040(D) points to Chapter 17.22, but detailed planter/tree ratios weren’t in retrieved excerpts Ask Planning for current Chapter 17.22 standards and any adopted guidelines.
Visibility triangles Tall landscaping/fences can create intersection hazards Confirm the design against § 17.16.140 (visibility at intersections/driveways). Not found in retrieved materials.
Fence height/placement Screening fences are allowed, but height/material limits vary Countywide fence height table wasn’t retrieved; confirm with staff and § 17.16.080 encroachment rules.
Stream/wetland buffers Planting or fencing inside buffers is restricted Make sure fencing doesn’t block flows or wildlife corridors under § 17.16.080(B)(2)(b).
Design Review scope Plant species/size and screen planting design can be conditioned If inside a DR Overlay, expect review under § 17.29.050 and § 17.11.020.
Telecom screening Chain link is not allowed in public view; landscaping must be maintained Apply § 17.25.210(5)–(6) and show irrigation/maintenance commitments.

Plain-English Summary

If you’re building in unincorporated Calaveras County, plan to landscape your street-facing edges and hide the “ugly stuff.” Multifamily lots must landscape front and street-side yards; most commercial and some industrial frontages need a landscaped strip; and any HVAC or propane tank sitting in a front setback must be hidden with plants or a solid fence. All new landscaping must follow state water-efficiency rules.
