Placerville — Landscaping and Screening

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

Last reviewed: July 2, 2026

Overview

This page summarizes what Placerville's Title 10 Zoning ordinance requires for landscaping, screening, buffers, fences/walls, and trees. It pulls the locally controlling rules (site-plan/submittal rules, zone-by-zone development standards, and the City's water‑efficient landscape chapter) and explains practical implications for applicants. For broader context see the city's Placerville zoning & planning overview and the specific Placerville Zoning and Placerville Development Standards pages.

Key controlling ordinance sections used below include the site plan/design review rules (which require landscaping plans), the zone development standards (for landscaping/refuse/screening requirements in each zone), and the Water Efficient Landscape Regulations in Chapter 6 of Title 10. Where the code states a requirement I cite the controlling section (§) and the file search result that contains it.

How to read this page

Bolded terms are the zone names and numeric standards you need to scan for (e.g., R-1, 6' wall).
First natural mention of related topics is linked inline to the city menu pages: Placerville Zoning, Placerville Parking, Placerville Development Standards, Placerville Design Review, Placerville Overlay Districts, Placerville ADUs, and the California Building Standards Code.

What the code requires (top-line)

A landscaping plan is required with site or design review submittals; the plan must show plantings, screening, fences/walls, and identify significant trees. § 10-4-9(E)(1)(2) .
Projects with aggregate landscaped area ≥ 500 sq ft (new projects) or rehabilitated landscapes ≥ 2,500 sq ft must comply with the City’s Water Efficient Landscape Regulations (Chapter 6, Title 10). § 10-6-3 .
Parking lots have numeric landscape and shade requirements (minimum 20% landscaped; shade tree targets so that at 15-year maturity at least 50% of paving is shaded at June 21 solar noon). § 10-4-16(g) and related design criteria .
Screening of service areas, refuse enclosures, mechanical equipment and other “unsightly” uses is mandatory by walls, fences, planting or combination. For refuse in commercial/professional zones the code sets a minimum decorative wall height (for refuse) of 5½ ft. § 10-4-16(j) and § 10-5-13(F)(8)(a) .
Fences/walls on required yards are allowed but height limits and visibility-triangle rules apply (residential corners: max 3 ft in corner sight triangle; elsewhere usually 6 ft). § 10-4-3(C) .
Mobilehome parks require a dedicated 6 ft screening wall/fence along street frontages and landscaped street setbacks with irrigation (conditional use/permit standards). § 10-4-15(F)(1)(c–d) .
Landscape plans must address irrigation design, hydrozones, meters/backflow, maximum applied water allowance and irrigation audits as required by the water‑efficient chapter (appendices and design criteria). See irrigation plan requirements. § 10-6-4 (definitions) & 10-6 design criteria .

District-by-district breakdown (how landscaping & screening differ by zone)

Note: each district subsection below states the zone name as it appears in Title 10 and then highlights landscaping/screening rules that are specific to that zone plus the development standards that affect where plantings and fences can be located. For site- or project-specific questions, verify with the jurisdiction.

R-1 (10,000) – Single‑Family Residential

Purpose: low‑density single‑family. § 10-5-7(A) .
Typical permitted uses: single-family homes, accessory dwelling units (ADUs) subject to ADU rules. § 10-5-7(B) ; see Placerville ADUs.
Key dimensional/landscape-relevant standards: Front setback 20 ft; side setbacks 10% or 10 ft; rear 20 ft; max height 35 ft. § 10-5-7(D)1–7 .
Landscaping & screening implications: R-1 projects that require site plan or are part of multi‑lot developments must submit landscaping plans and comply with the City’s general landscaping/planting protections and the Water Efficient Landscape Regulations if the planted area triggers the thresholds. Design criteria require tree protection and landscape treatment to preserve natural patterns. § 10-4-9(G) and § 10-6-3 .

R-1 (6,000) – Single‑Family Residential (medium lot)

Purpose & permitted uses: similar to R-1 (10,000) but higher density; ADUs allowed under the ADU rules. § 10-5-8 .
Key dimensional standards: typical front 20 ft; max coverage 35%; lot widths and yards differ (see §). § 10-5-8(D) .
Landscaping & screening: same citywide landscape rules apply; where curbs/parkways exist tree planting expectations (parkway tree per ~40 ft of frontage) and tree protection language apply in development submittals. § 10-5-13(F)(7)(d) and design review criteria § 10-4-9(G) .

R-1A – Single‑Family Acre / Rural Residential

Purpose: low density, preserve rural/topographic character. § 10-5-5(A) .
Landscaping & screening: more flexibility for natural vegetation preservation; some roadway/curb requirements are different. Large trees and woodland alteration are addressed at tentative map/subdivision stage (tree canopy retention plans / woodland permits). § 10-11-6(A)(4) .

R-2 / R-3 / R-4 – Multi‑family / Transitional Residential zones

Purpose: medium- to higher-density multi-family. § 10-5-9 (R-2) and comparable R-3/R-4 sections. § 10-5-9 .
Landscaping implications: multi‑family developments are commonly subject to mandatory site plan review; the planning commission’s design criteria explicitly require landscape/site treatment and tree preservation, landscape planter strips in parking, and shading standards for parking. § 10-4-9(G) & § 10-4-16(g–h) .

R-5 – Very High‑Density Multi‑Family

Purpose: encourage high-density multi‑family. § 10-5-12(A) .
When site plan review or design review is required, landscape plans are required and must meet the City’s water-efficient and tree‑preservation rules; the R‑5 zone also explicitly references the site plan review process. § 10-5-12(E) and § 10-4-9 .

BP – Business‑Professional (Commercial/Office)

Purpose: professional offices and compatible commercial uses. § 10-5-13(A) .
Key landscaping rules inside BP:
- All open areas (except accessways, walking surfaces and parking) must be landscaped and irrigated and maintained. § 10-5-13(F)(7)(a) .
- Parking: 24 sq ft planting area with a tree per 10 single-row parking stalls (minimum 15‑gal trees); see the BP planting ratio. § 10-5-13(F)(7)(b–d) .
- Refuse storage must be screened by a min. 5½ ft decorative block/masonry wall (or comparable material and gate). § 10-5-13(F)(8)(a) .
Screening and mechanical equipment: required to be fully screened. § 10-4-16(j–k) .

CBD – Central Business District & Historic Areas

Purpose: downtown commercial core (CBD references appear in site plan review rules). § 10-4-9(E) .
Landscaping/screening considerations: design review emphasizes compatibility with historic small‑town character; landscaping must enhance streetscape, maintain vistas, and protect trees—application submittals must include a landscaping plan and screening/fence locations. § 10-4-9(E)(1)(2) & § 10-4-9(G)(3) .

PF – Public Facilities

Projects in PF that require new construction are subject to site plan review, including landscaping and tree protection shown on plans. § 10-4-9(E) .

Overlay districts and special cases

Overlay zones (AO, HO, CBO, CBO/ Cannabis overlay etc.) modify the underlying zone and may impose special landscape/screening requirements (airport compatibility, historic overlay protections, HO design review). Always check the overlay map and the overlay section for added submittal and design constraints. § 10-5-25 (CBO), AO overlay sections, HO overlay .
Subdivisions / vesting tentative maps must include tree canopy retention plans and may require woodland alteration permits and fuel modification plans for heavily vegetated sites. § 10-11-6(A)(4–6) .

Practical guidance — how to prepare an application

Always include a complete landscape documentation package when your project triggers site plan / design review or the water‑efficient thresholds: a landscape plan, irrigation design plan, hydrozone table, and a certificate/completion documents per § 10-6. § 10-6-11 → 10-6-18 .
Show all existing trees ≥ 7.5" and identify any that will be removed; include a tree preservation or canopy retention plan for subdivisions. § 10-11-6(A)(4) and submittal lists for design review § 10-4-9(E)(1)(2) .
For parking, follow the measurable standards: calculate required planter area and tree counts and include shading projections at 15‑year maturity as part of the landscape narrative. § 10-4-16(g) .
If your project uses recycled/gray water or captured rainwater to irrigate, document it per § 10-6 exceptions and meter/irrigation plan rules. § 10-6-3(C) .
Include screening details for refuse, mechanical equipment, loading/service yards, and satellite dishes where visible from rights-of-way; show construction materials for walls and gates (masonry, wood gate, etc.) consistent with the applicable zone standard. § 10-5-13(F)(8) and § 10-4-16(j) .
Expect planning staff or the planning commission to require landscape maintenance assurances (maintenance agreement or CC&Rs) on projects where the code explicitly requires them (e.g., mobilehome parks). § 10-4-15(F)(1)(e) .

Checklist

Determine whether project triggers water‑efficient landscape rules (≥ 500 sq ft new landscaping). § 10-6-3
Prepare a full landscaping plan showing plant species, sizes, hydrozones, irrigation plan, and timers/controllers per § 10-6 requirements. § 10-6 (design & irrigation plan)
List and show on plan all trees ≥ 7.5 in DBH and provide tree protection/preservation plans if required. § 10-11-6(A)(4)
Show screening for refuse, mechanical equipment, service yards; show wall heights and materials. § 10-5-13(F)(8)
For parking lots: show planter area, tree count, and shading calculations for 50% paving at maturity (15 yrs). § 10-4-16(g)
If in a special overlay (historic, airport, HO), check overlay rules and include required reports (historic advisory review, ALUCP consistency, etc.). Overlay sections
If mobilehome park or similar conditional use, include landscape maintenance agreement language and show 6 ft screening walls where required. § 10-4-15(F)(1)(c–e)

Risks & Ambiguities

Issue	Why it matters	What to verify
Exact plant species or city plant list to use	The code requires water‑efficient and locally appropriate species but does not publish a definitive full plant list in the excerpts retrieved	Verify whether the Development Services Department or local landscape program has an accepted plant list; check § 10-6 design criteria and any local lists. § 10-6
Precise section that requires tree protection for small projects	Tree protection and identification appear in multiple submittal lists (subdivisions, site plans, mobilehome parks) but the code does not always state a single cross‑cutting tree permit for small remodels	For parcel‑specific tree permit requirements, confirm with Planning/Development Services. See vesting tentative/woodland plan rules § 10-11-6(A)(4)
Fence materials and design for corner visibility triangles	Height limits are explicit but acceptable materials and visibility treatments can be subjective during design review	Submit detailed fence elevations; confirm with planning staff; you may be eligible for a minor deviation under § 10-3-5 to adjust fence height up to 20%. § 10-4-3(C) and § 10-3-5
Fire‑safety vs. landscape density in WUI areas	Code requires defensible-space considerations and references PRC § 4291 for fire safety; conflicts can arise between dense screening and defensible space requirements	Verify fuel‑modification and fire‑district requirements and include fuel modification plans where required. § 10-6 (fire prong guidance) & § 10-11-6(A)(6)
When screening reduces required parking/landscape area	Tradeoffs (planter area vs. driveway space) may affect parking compliance and the planning commission may require changes at review	Coordinate parking plan and landscape plan together; check § 10-4-4 and site plan review criteria § 10-4-9. § 10-4-9

Plain‑English summary

Placerville requires you to draw up and submit a landscaping plan whenever the project is reviewed (site plan, design review, subdivisions) and to meet measurable requirements for parking landscaping, tree protection, irrigation design and screening of service/refuse/mechanical areas. Water‑efficient rules kick in at 500 sq ft of new landscape. Fences and walls have clear height/visibility limits; mobilehome parks have a mandatory 6‑ft street screening wall. Always show significant trees on plan and be prepared to provide a maintenance agreement for common landscaping. See the cited ordinance sections for the exact wording. § 10-4-9, § 10-4-16, § 10-4-15, § 10-6-3 .

Frequently asked questions

What landscaping plan information is required for a Placerville site plan submittal?

You must submit a landscape plan showing proposed plantings and screening, locations and heights/materials of fences and walls, and identification of existing trees; the submittal requirements explicitly list a landscaping plan and screening locations with site plan reviews. See § 10-4-9(E)(1)(2) .

When do Placerville water‑efficient landscaping rules apply?

Water‑efficient landscape regulations apply to new development with an aggregate landscape area of 500 sq ft or more and to rehabilitated landscapes with aggregate area 2,500 sq ft or more; smaller projects may follow prescriptive measures in the chapter’s appendices. See § 10-6-3 .

Do parking lots need trees or shade in Placerville?

Yes. Parking areas must include landscaped spaces and trees; at minimum 20% of parking areas must be landscaped with shrubs/grounds and tree planters, and shade tree planting must be sized to provide roughly 50% shade of paving at 15‑year maturity (June 21 standard). § 10-4-16(g) .

Are there mandatory screening heights for mobilehome parks?

Yes — mobilehome parks (as allowed in residential zones with a CUP) require a minimum 6 ft screening wall or fence along public street frontages; the street setback strip must be landscaped with street trees and automatic irrigation, subject to Planning Commission approval. § 10-4-15(F)(1)(c–d) .

How high can I build a fence on my residential corner lot?

In all residential zones a fence, wall or hedge may be up to 6 ft on required yards, but on corner parcels the portion within the sight triangle (triangle formed by intersecting rights of way and points 30 ft along the right-of-way) is limited to 3 ft to preserve sight lines. § 10-4-3(C) .

Does Placerville require tree protection for subdivisions?

Yes — vesting tentative map and subdivision submittals must include tree canopy retention plans and a woodland alteration permit if applicable, and large trees must be identified on plans (individual trees with diameter > 7.5 in are called out in submittal lists). § 10-11-6(A)(4) .

Are refuse enclosures required to be screened in commercial zones?

Yes — refuse storage areas for business-professional uses must be screened on all sides from public view by a decorative concrete, block or masonry wall with a minimum height of 5½ ft, with durable gates. § 10-5-13(F)(8)(a) .

If my project uses recycled or gray water for irrigation, does the code treat it differently?

Yes. Projects using treated or untreated gray water or captured rainwater that meet landscape water requirements under the thresholds may be subject to modified compliance steps in the water‑efficient chapter (see § 10‑6 exceptions). § 10-6-3(C) .

Will design review require a maintenance guarantee for landscaping?

For some discretionary permits (e.g., mobilehome parks, conditional uses), the code requires a landscape maintenance agreement to ensure ongoing maintenance; design review often includes maintenance conditions. § 10-4-15(F)(1)(e) .

Where do I check overlay special rules (historic, airport) that affect landscaping and screening?

Check the specific overlay district section in Title 10 (AO airport overlay, HO historic overlay, CBO/Cannabis Business Overlay) — overlays supplement the base zone and can add or change standards and submittal requirements. See the overlay sections in Title 10 and the Placerville Overlay Districts page. Overlay sections (e.g., AO / HO) .
