Pyrophytic Plants

Inspectors may note the presence of specific species of "pyrophytic" plants present within 30' of structures or 10' of roads and driveways on your property.  Section 4907.2 of the California Fire Code, as amended and adopted by your fire agency, requires removal of pyrophytic, combustible vegetation within 30' of structures and/or 10’ of roads or driveways.

What should I do?
Please remove these plans and replace with a fire resistant species.  If the removal creates a hardship, please contact us for assistance - in some cases, we can help you modify vegetation or create a plan to remove and replace vegetation over time

1. Remove all branches within 10’ of any chimney or stovepipe outlet. 

Description

What should I do?
Please cut back limbs with foliage that are within 10' of a chimney outlet.  Contact us if removing the limb would cause harm to the structure or health of the tree.

Fire Code Reference

2. Remove all leaves, needles and dead vegetation on roofs, gutters, decks, porches, stairways, etc. 

Description

What should I do?
Please regularly remove fallen leaves, needles, twigs, and other dead vegetation from your roof, rain gutters, decks, proches, exterior stairs, and from around the base of exterior walls.

Fire Code Reference
[2016 CFC §4907.2, PRC §4291(a)(6)] 

3. Remove all dead and dying trees, branches, shrubs, and plants adjacent to buildings or overhanging roofs. 

Description

What should I do?
Please remove any dead vegetation immediately adjacent to or overhanging structures on your property.  Look for dead limbs in trees and dead shrubs.  Some shrubs may have dead woody vegetation beneath a visible layer of green foliage.  

Fire Code Reference
[2016 CFC §4907.2]

 4. Remove all dead grass, plants, shrubs, trees, branches, leaves, weeds and needles within 30’ of structures.

What should I do?
Please remove any dead vegetation within 30' of structures.  Look for dead grasses, shrubs, landscaping plants or bnative vegetation.  Some shrubs may have dead woody vegetation beneath a visible layer of green foliage.  This may include fallen limbs and leaves.

Fire Code Reference
[2016 CFC §4907.2]

5. Remove or separate live combustible ground cover and shrubs within 30’ of structures. 

Description

What should I do?
Please add separation betwen shrubs to prevent fire from spreading between individual plants.  This may require pruning shrubs or removal when plantings are dense or close together.  This often refers to plants such as juniper, rosemary, some ornamental grasses, bamboo, and other combustible species.  See www, firesafemarin.org/plants for details on fire hazardous plants.

Fire Code Reference
[2016 CFC 4907.2.  SRA areas: PRC §4291(a)(1) and BOF Guidelines #1.]

6. Remove combustible vegetation and materials, on, adjacent to, or below combustible decks, balconies, stairs.

Description

What should I do?
Please look for vegetation beneath decks, porches, balconies and exterior stairs.  Remove all vegetation growing beneath these structures to prevent the spread of fire to vulnerable undersides of overhangs and decks.

Fire Code Reference
[14 CCR §1299.03(a)(4)]

7. Relocate exposed firewood or lumber outside of zone 1 unless covered in a fire resistive material.

Description

What should I do?
Firewood may not be stored exposed on decks or adjacent to structures.  Please relocate or cover firewood and lumber piles.  You may move piles more than 30' from structures, move them indoors, or alternately cover them tightly with a fire resistant cover (such as a heavy tarp or canvas. or in a tightly enclosed shed - no specific product exists) to prevent embers from igniting the wood.  Storing firewood indoors in a garage or shed is better than leaving it exposed.  Keep firewood piles free of leaves, needles, and fine vegetation that can act as "kindling" and ignite from embers during a wildfire.  

Fire Code Reference
[14 CCR §1299.03(a)(3)]

8. Cut annual grasses and forbs (weeds) to a maximum of 4” in height. 

Description

What should I do?
Please mow or cut all dry, cured grasses and weeds to a maximum of 4" in height.  Cut grasses may remain on ground (no deeper than 4"), however we recommend raking and removing clippings for maximum fire-resistance.   You may need to cut grasses more than once each year if it grows back.

Use plastic string trimmers, and be sure to only use gas powered mowers in the morning when vegetation is moist and temperatures are cool.  Metal bladed mowers and trimmers can spark fires.  Never use outdoor power tools on a Red Flag day.

Fire Code Reference
[2016 CFC §4907.2, 14 CCR §1299.03(b)(2)(B)]

9. Provide separation between shrubs and trees, with increased separation on slopes. 

Description

What should I do?
Please remove any shrubs growing beneath trees which create "ladder fuels" to carry fire from the ground into trees.  Provide separation between shrubs and trees by pruning aggressively or removing individual plants.  Add additional space on slopes.  Follow the helpful guidelines in this FIRESafe MARIN brochure to ensure compliance.

Fire Code Reference
[2016 CFC §4907.2, PRC §4291(a)(4)]

Frequently Asked Questions

Why did you inspect my property?

Ross Valley Fire Department has conducted annual "grass hazard" inspections for at least 40 years.  In March 2017, Sleepy Hollow Fire Protection District (SHFPD) adopted the Sleepy Hollow Wildfire Hazard and Wildland Urban Interface Area Assessment and Report.  This comprehensive report analyzes risk, identifies specific hazards, and outlines steps needed to help reduce the threat of catastrophic wildfires in Sleepy Hollow.

Following two public planning meetings, SHFPD approved the implementation of the report’s recommendations, beginning with additional free chipper days, wildfire education programs, parcel-by-parcel hazard inspections, and many other preparedness and prevention programs recommended in the report. 

These inspections help ensure compliance with the laws (Section 4290 and 4291 of the CA Public Resources Code) and contribute to the overall safety of Sleepy Hollow and neighboring communities.

Why didn't you inspect my neighbor's property?

We did!  All properties are inspected annually.  Your neighbor received a notice, too, and we'll follow up to ensure all neighbors comply.  If you see a hazard, or think we missed something, please This email address is being protected from spambots. You need JavaScript enabled to view it..

What right do you have to inspect my property?

The California Fire Code and Public Resources Code grant the authority for the Fire Chief or authorized FIre Code Official to conduct inspections for compliance with the various applicable codes.

The inspectors do not enter a property without permission.  They are trained to walk up to a front door (through an unlocked front gate at the street, if present, under rules of curtilage), and knock to introduce themselves.  If no adult is present, they have two options: 1) inspect the property as visible from the front door or public areas such as from the front pathway or roadway, or 2) come back later.  Under no circumstances do the inspectors enter locked or gated areas of a property without permission of a resident or landowner, and they don't "peek" over fences.  They only inspect areas that are plainly visible from a common area unless an adult resident gives permission to gated areas.

What are the exact laws I'm required to comply with?

What happens if I am unable to, or refuse to, comply?

  • Section 4907.4 of the CA Fire Code outlines the process to abate hazards if a property owner fails to comly.  Your fire department would prefer to work with your to help you crete a safe space around your home, so please contact us for assistance if you are unable to comply.

What is a "Pyrophytic" plant species?

Plants that ignite readily and burn intensely (pyro-phases) typically share certain characteristics:

  • They are usually blade-leaf or needle-leaf evergreens. 
  • They have stiff, woody, small or fine, lacey leaves. 
  • Their leaves and wood usually contain volatile waxes, fats, terpenes or oils (crushed leaves have strong odors). 
  • Their sap is usually gummy, resinous and has a strong odor. 
  • They usually contain plentiful fine, twiggy, dry or dead materials. 
  • They may have pubescent (hair covered) leaves. 
  • They may have loose or papery bark. 
  • These plants flame (not smolder) when preheated and ignited with a match. 

FLAMMABILITY & CONDITION 
The condition of the plant is as important as its species. Even some "pyrophytic" species can be quite fire-resistant if properly maintained. Depending on its growth form and access to water, the same species may be fire resistant in one envi-ronment and pyrophytic in another.  Water-stressed plants that are in poor condition are more pyrophytic. A pyrophytic species becomes explosively flamma-ble when poorly maintained.  South-facing slopes, windy areas, sites with poor soils and urban landscapes are more stressful for plants. 

PYROPHYTIC VEGETATION TYPES:
  • Grasses: Any cured (dry) grass. Nonirrigated, annual grasses are typically more flammable than perennial grasses. Irrigated grasses are fire resistant. 
  • Herbs: Any cured herb. 
  • Ferns: Any dry or cured fem, particularly cured bracken and sword fems. 
  • Brush: Any brush with excessive deadwood. Any over-mature, dying or dead brush. 
  • Trees: Any forest, stand or urban forest that is over-dense, under stress or over mature.

WHY ARE THE FIRE INSPECTORS WEARING MARIN COUNTY FIRE DEPARTMENT UNIFORMS?

In order to complete 826 inspections in a one-week period, SHFPD cooperates with Marin County Fire Department (MCFD).  They provide a team of trained inspectors, who under the authority of the Fire Chief, inspect properties for compliance with the CA Fire Code Section 4907.2, 4907.3, and Public Resource Code (PRC 4291).
