CWUIC · California Wildland-Urban Interface Code

What plant mapping and species information is required in a final fire protection plan?

Q: Do I need scientific names or are common names enough?

You must provide both scientific (botanical) and common names in the plant legend. § 603.3.1(4) .

Q: Must the plan show future (mature) sizes?

Yes — the plan must list the expected height and width for mature growth for each species so reviewers can assess future fuel continuity. § 602.3.2(1.3) .

Q: Are irrigated areas treated differently on the plan?

Yes — the plan must identify irrigated and nonirrigated zones , because irrigation affects plant growth and maintenance expectations. § 602.3.2(2); § 603.3.1(3) .

Q: Do I need to include legal language in the plan?

Yes — the final fire protection plan must include legally binding statements about community responsibility for maintenance and required CC&R statements for property‑owner responsibilities. § 602.3.2(5–6) .

If your project needs a final fire protection plan, you must submit a map showing every plant proposed inside the fuel modification zones, a legend with a unique symbol per species, and for each species list the plant life‑form, scientific and common names, and expected mature height and width — and clearly mark irrigated vs nonirrigated zones, emergency access vegetation reduction, maintenance access points, and legally binding maintenance responsibilities (per **§ 602.3.2** and **§ 603.3.1(1)**).

What the code requires — 2-4 sentences

The final fire protection plan must include a map of all proposed plants inside the project’s fuel modification zones, with a legend showing a symbol for every proposed plant species, and specific data for each species: the plant life‑form, the scientific and common name, and the expected height and width at maturity — § 602.3.2. The plan must also identify irrigated and nonirrigated zones, show vegetation reduction around emergency access/evacuation routes, and include legally binding maintenance statements and access points for maintenance personnel and equipment, as required by § 602.3.2. Landscape plans required by the code official must also delineate the 30‑foot (9144 mm) and 100‑foot (30 480 mm) fuel management zones and include a plant legend (botanical + common names) and groundcover identification in the 30‑foot zone — § 603.3.1(1).

The single most important rule: the final plan must show every proposed plant in the fuel modification area on a map with a legend and species‑specific data (life‑form, botanical/common name, and mature size). § 602.3.2.

Requirements in detail

Core mapping and species data (what you must show)

A map identifying all proposed plants located in the project’s fuel modification zones, with a legend that assigns a unique symbol to each plant species. § 602.3.2.
For each proposed species, specific information including at least:
- Plant life‑form (e.g., tree, shrub, groundcover), scientific and common name, and expected mature height and width. § 602.3.2(1.1–1.3).
Identification on the plan of irrigated versus nonirrigated planting zones. § 602.3.2(2).
Vegetation reduction requirements and locations around emergency access and evacuation routes. § 602.3.2(3).
Points of access for equipment and personnel to maintain vegetation in common areas. § 602.3.2(4).
Legally binding statements about community and owner responsibility for maintenance of fuel modification zones, and required CC&R language. § 602.3.2(5–6).

Landscape plan contents when required by the code official

Delineation of the 30‑foot (9144 mm) and 100‑foot (30 480 mm) fuel management zones measured from structures. § 603.3.1(1).
Identification of existing vegetation to remain and proposed new vegetation (i.e., show both). § 603.3.1(2).
Identification of irrigated areas. § 603.3.1(3).
A plant legend with both botanical and common names and the identification of all plant material symbols (ties back to the map required in § 602.3.2). § 603.3.1(4).
Identification of ground coverings within the 30‑foot zone. § 603.3.1(5).

Decision‑relevant dimensions/values (quick reference table)

Item required on plan	Decision‑relevant value or content	Code Reference
Map of proposed plants in fuel modification zones	Symbol for each species shown on map legend	§ 602.3.2
Species data	Plant life‑form, scientific & common name, expected mature height & width	§ 602.3.2(1.1–1.3)
Irrigation zones	Identify irrigated vs nonirrigated areas on plan	§ 602.3.2(2)
Emergency access vegetation reduction	Location and requirements around emergency/evac routes	§ 602.3.2(3)
Access points for maintenance	Points of access for equipment/personnel in common areas	§ 602.3.2(4)
Maintenance covenants	Legally binding community and CC&R statements	§ 602.3.2(5–6)
Fuel management zone delineation	30‑ft (9144 mm) and 100‑ft (30 480 mm) zones from structures	§ 603.3.1(1)
Existing vs proposed vegetation	Identify which plants remain vs new plantings	§ 603.3.1(2)
Plant legend format	Both botanical (scientific) and common names	§ 603.3.1(4)
Groundcover in 30‑ft zone	Identify type of groundcover within 30‑ft zone	§ 603.3.1(5)

Exceptions & special cases

The CWUIC text requires content “when a landscape plan is required by the code official” — whether a landscape plan is required is discretionary. If the code official does not require a landscape plan, the specific 603.3.1 items may not be mandatory for that permit submission. See § 603.3 and § 603.3.1.
The code contains separate provisions about fire‑smart vs nonfire‑smart trees and exceptions for certain trees; those provisions (e.g., § 603.4 and exception language) affect plant selection and whether a tree may be allowed despite not being fire‑smart. The explicit allowance or exception language is outside the narrow mapping/species list in § 602.3.2, so consult § 603.4 for plant‑classification rules.
The final plan must also include items listed in the preliminary plan requirements (site maps, boundaries, contours, fuel modification zone methods) — you must not omit § 602.3.1 items; they are required upstream of § 602.3.2. § 602.3.1 / § 602.3.2.

If you need more detail about what the code considers fire‑smart vegetation or the allowed exceptions for trees, that text is in Section 603.4 and related subsections; those provisions were not reproduced fully in the search snippets above, so consult § 603.4 directly for classification criteria.

Common mistakes

Omitting scientific (botanical) names and providing only common names — the code explicitly requires both (plant legend). § 602.3.2; § 603.3.1(4).
Failing to show expected mature height and width for each species — reviewers need this to assess future fuel continuity and canopy separation. § 602.3.2(1.3).
Not distinguishing irrigated vs nonirrigated areas on the plan — irrigation status affects growth expectations and maintenance regimes. § 602.3.2(2); § 603.3.1(3).
Forgetting to delineate the 30‑ft and 100‑ft fuel management zones from structures when a landscape plan is required. § 603.3.1(1).
Leaving out legally binding maintenance statements and CC&R language for communities or common areas — these are explicitly required in the final plan. § 602.3.2(5–6).

Worked example — single‑parcel / small subdivision (concrete)

Scenario: A 6‑lot subdivision in a VHFHSZ requires a final fire protection plan and a landscape plan.

What to show on the final plan:

Map: Draw the subdivision parcel map and overlay the fuel modification zone boundaries; create a legend with symbols A, B, C for each proposed species. (Required by § 602.3.2).
Species entries (example entries in the plant legend):
- Symbol A — Shrub; Botanical name: Salvia X (example) — Common name: “Sage”; Expected mature size: 4 ft height × 6 ft width. § 602.3.2(1.1–1.3).
- Symbol B — Small tree; Botanical name: Exampleus arboreus — Common name: “Small Oak”; Expected mature size: 20 ft height × 15 ft width. § 602.3.2(1.1–1.3).
Irrigation: Shade or hatch areas where irrigation will be provided (e.g., planting wells and common‑area drip lines), label all other plantings as nonirrigated. § 602.3.2(2); § 603.3.1(3).
Fuel management zones: From every structure footprint show the 30‑ft (9144 mm) inner zone and the 100‑ft (30 480 mm) outer zone; annotate which proposed plants are within each zone. § 603.3.1(1).
Groundcover: Within the 30‑ft zone identify hardscape, low‑fuel groundcovers, mulch types or exposed soil as required. § 603.3.1(5).
Access & maintenance: Mark equipment access points around common areas and a note specifying who is responsible for ongoing maintenance. Add CC&R sample wording or reference required legally binding maintenance covenants. § 602.3.2(4–6).

Why these specifics matter: the reviewer will verify the map symbols match the plant legend (scientific+common names) and that mature sizes are reasonable for spacing and defensible‑space objectives; irrigated areas will be treated differently than nonirrigated when assessing future fuel growth.

6 FIRE PROTECTION REQUIREMENTS

User notes:

About this chapter: In addition to the building construction requirements in the California Building Code and California Residential Code, this chapter contains requirements for development and construction in Local Responsibility Areas (LRA) designated as Very High Fire Hazard Severity Zones and areas designated by the State Fire Marshal as State Responsibility Areas (SRA). While many of these provisions are found in Title 14 and Title 19 of the California Code of Regulations, they are replicated here for the code user. The local jurisdiction has the authority to apply the same regulations to LRA when the regulations are adopted by local ordinance.

The requirements in this chapter reference the process for adoption of Very High Fire Hazard Severity Zones in the LRA; criteria for evaluating existing subdivisions that are at significant fire risk and are without an adequate secondary egress; and criteria for fire safety provisions required in the Safety Element of a city or county General Plan.

The chapter includes mitigation strategies to reduce the hazards of fire originating within a structure spreading to wildland and fire originating in wildland spreading to structures. These strategies are included in the following requirements:

1. Development of fire protection plans.

2. Development of landscape plans and long-term vegetation management.

3. Creation and maintenance of defensible space to protect structures and subdivisions.

SECTION 601—GENERAL

601.1 Scope. The provisions of this chapter establish general requirements for new and existing buildings, structures and premises located within wildland-urban interface (WUI) areas .

601.2 Objective. The objective of this chapter is to establish minimum requirements to mitigate conditions that might cause a fire originating in a structure to ignite vegetation in the wildland-urban interface (WUI) area, and conversely, a wildfire burning in vegetative fuels to transmit fire to buildings and threaten to destroy life, overwhelm fire suppression capabilities or result in large property losses.

601.3 Chapter 6 definitions. Where used in this chapter, the term listed below shall be defined as follows:

DEFENSIBLE SPACE. The buffer that landowners are required to create on their property between a “Building or Structure” and the plants, brush and trees or other items surrounding the “Building or Structure” that could ignite in the event of a fire. [CCR Title 14 §1299.02(a)]

SECTION 602— FIRE PROTECTION PLANS

602.1 General. The code official is authorized to require the owner or owner’s authorized agent to provide a fire protection plan. The fire protection plan shall be prepared to determine the acceptability of fire protection and life safety measures designed to mitigate wildfire hazards presented for the property under consideration.

The fire protection plan shall be prepared by a registered design professional, qualified landscape architect, qualified fire safety specialist or similar specialist acceptable to the code official and shall analyze the wildfire risk of the building, project, premises or region to recommend necessary changes.

The code official is authorized to require a preliminary fire protection plan prior to the submission of a final fire protection plan.
CWUIC § 302.1 Medium relevance — show source text
SECTION 302—WILDLAND-URBAN INTERFACE AREA DESIGNATIONS

302.1 Mapping . The State Fire Marshal shall classify lands into Fire Hazard Severity Zones in accordance with California Public Resources Code, Sections 4201 through 4204 for State Responsibility Areas and in accordance with Government Code, Sections 51175 through 51189 for Local Responsibility Areas. The State Fire Marshal shall designate areas in the state as fire hazard severity zones and assign each zone based on the severity of fire hazard that is expected to prevail in those areas. Each fire hazard severity zone shall embrace relatively homogeneous lands, and the classification shall be based on fuel loading, slope, fire weather and other relevant factors including areas where winds have been identified by the Office of the State Fire Marshal as a major cause of wildfire spread and other areas designated by the enforcing agency to be at a significant risk from wildfires.

302.2 Review of wildland-urban interface areas. The code official shall reevaluate and recommend modification to the wildlandurban interface areas in accordance with Section 302.1 on a 5-year basis or more frequently as deemed necessary by the legislative body. The State Fire Marshal shall periodically review the areas in the state identified as fire hazard severity zones and, as necessary, shall make recommendations relative to fire hazard severity zones. This review shall coincide with the review of state responsibility area lands every five years and, when possible, fall within the time frames for the county’s general plan update.

Frequently asked questions

What counts as a plant “symbol” on the map?

A plant symbol is any distinct graphic (letter, color, hatch or icon) used consistently on the map and matched to the plant legend. The code requires a symbol for each species in the fuel modification zones. § 602.3.2.

Do I need scientific names or are common names enough?

You must provide both scientific (botanical) and common names in the plant legend. § 603.3.1(4).

Must the plan show future (mature) sizes?

Yes — the plan must list the expected height and width for mature growth for each species so reviewers can assess future fuel continuity. § 602.3.2(1.3).

Are irrigated areas treated differently on the plan?

Yes — the plan must identify irrigated and nonirrigated zones, because irrigation affects plant growth and maintenance expectations. § 602.3.2(2); § 603.3.1(3).

Do I need to include legal language in the plan?

Yes — the final fire protection plan must include legally binding statements about community responsibility for maintenance and required CC&R statements for property‑owner responsibilities. § 602.3.2(5–6).
