Enhancing Fire Safety in San Diego Zone 0 Defensible Space: Landscape Renovation Ideas by Greenway

As wildfire awareness and preparedness grow in San Diego, the introduction of San Diego Zone 0 defensible space offers homeowners a proactive way to protect their properties. Zone 0 focuses on creating a non-combustible buffer within five feet of structures, significantly reducing the risk of wildfire damage. Here’s a guide on what Zone 0 involves, how to approach landscape renovations for fire safety, and how Greenway Landscape Design & Build can help you create a beautiful, fire-safe outdoor environment.

Zone 0 Map for San Diego Homes

The goal is to start at your house and work outward, reaching up to 100 feet or your property line. Zone 0: Zone 0 extends 0- 5 feet from your home, focusing on intense fuel reduction to protect against ember attacks. Zones 1 & 2: These zones cover up to 100 feet around your home. They’re required by law and involve varying levels of vegetation management.
Understanding Zone 0 in San Diego: The New Fire-Safe Buffer Zone

Zone 0 covers the five feet closest to any structure on your property, including walls, decks, and attachments. Designed to minimize fire risk, by focusing on intense fuel reduction to protect against ember attacks, this zone discourages the use of combustible materials and promotes hardscaping to reduce flammable vegetation and debris.

Technically the Zone 0 defensible space became law in California with the passing of Assembly Bill 3074 (AB 3074) on January 1, 2021; however, full enforcement is expected to be phased in, with new construction potentially seeing enforcement sooner than existing structures, with full implementation anticipated around 2025-2026 depending on the final regulations from the State Fire Marshal.

While not currently enforced for existing residential homes in San Diego, Zone 0 is a crucial component in wildfire defense, helping prevent fires from reaching and spreading to your home. Here are the recommended guidelines for creating a safe Zone 0:

  • Opt for gravel, pavers, or concrete in place of combustible mulch
  • Regularly clear dead weeds, dry grass, and debris, and inspect roofs, gutters, and outdoor areas for buildup
  • Keep branches trimmed at least 10 feet from chimneys and stovepipes
  • Limit combustible items like furniture and planters on decks
  • Store firewood and lumber in Zone 2 (More than 5 feet from the home) for enhanced safety
  • Replace any combustible fencing and gates with fire-resistant materials
  • Place garbage and recycling containers in a safe area outside of Zone 0
  • Relocate boats, RVs, and vehicles away from Zone 0 to reduce fire hazards

These steps are designed to protect your home and property by reducing flammable materials within the immediate vicinity of your structure.

  1. Embrace Hardscaping for Non-Combustible Beauty

In Zone 0, hardscaping is one of the best strategies for creating a safe, non-combustible space. Pavers, gravel paths, stone walkways, and concrete & steel features add texture and visual appeal while reducing fuel sources close to your home.

Greenway Suggestion: Our team can help you design custom hardscaped elements, like elegant stone pathways or gravel beds, that are both attractive and fire safe. A fantastic non-combustible “planting” alternative to concrete features, is utilizing life-like steel plants, that are beautiful and have the look of San Diego’s native plants & cacti and are 100% fire resistant. Greenway installed many of these steel plants at Cal Fire’s Headquarters, located in Fallbrook, and they are now suggesting steel plants to residents looking to improve their fire safety. Hardscaping, in conjunction with concrete and/or steel features, can be a beautiful extension of your home’s design while keeping your property defensible.

  1. Minimize and Choose Fire-Resistant Plantings Carefully

While Zone 0 limits vegetation, fire-resistant plants can still add beauty and interest to this area. Choosing succulents, agave, and certain types of low-growing, non-flammable plants keeps the space visually appealing without increasing fire risk.

Greenway Suggestion: We recommend selecting low-maintenance, drought-tolerant plants that are naturally fire-resistant. Our team can advise on options that fit your San Diego neighborhood’s climate and meet the Zone 0 requirements.

  1. Install Decorative Gravel, Mulch Alternatives, and Stone Features

    If you like the look of bark, and need to create a decorative gravel space for Zone 0, Barkwood Gravel is a great option.

In place of flammable mulch, consider non-combustible materials like decorative gravel, sand, and rock. A great groundcover alternative, that has a look similar to bark, is “Barkwood Crushed Rock” which our clients are very happy with. These materials not only enhance the aesthetics of your landscape but also serve as effective fire barriers within Zone 0.

Greenway Suggestion: Greenway can install gravel or stone mulch around planting beds to create a stylish, fire-safe look. We also offer options for decorative rocks and stone features that add a unique touch while keeping your home safe.

  1. Keep Zone 0 Clean and Clear of Debris

Keeping Zone 0 clear of dead leaves, pine needles, and other debris is essential for minimizing fire risk. Routine maintenance is crucial to preventing combustible materials from accumulating in this high-risk area.

Greenway Suggestion: We can refer you to maintenance services to keep your Zone 0 area clean and compliant with fire safety standards. Regular visits to clear debris and maintain hardscapes will help you preserve both the beauty and safety of your outdoor space.
