More than 100M Americans live in or near forests and grasslands that can erupt in flames. Steve Inskeep reports on fighting wildfires, which cost federal agencies almost $2B last year

Fighting wildfires in America cost federal agencies almost $2 billion last year including more than half the budget of the U.S. Forest Service. Wildland fires are growing worse in a time of drought and climate change, and the biggest and most destructive fires can't be stopped. They are a force of nature: imagine trying to stop a hurricane. Yet the government has to try, because more than a 100 million Americans now live in -- or near -- forests and grasslands that can erupt in flames.

Years of experience by the California fire service have led to a new strategy for reducing the chance of building loss or damage due to wildfire, with new regulations that are now mandatory within the Wildland Urban Interface (WUI). It is a two-pronged approach – providing defensible space and constructing a more ignition-resistant structure.

​EXTERIOR WILDFIRE EXPOSURE PROTECTION:

 Buildings are now required to be constructed so that they have less chance of catching fire from burning embers from wildfires. Most of the highest wildfire losses take place during hot, windy days or nights when flames spread so fast that many buildings catch fire and overwhelm available firefighting forces. Many buildings ignite when burning embers land on wood roofs, blow in through vents, pile up in cracks, or become lodged under boards. By constructing buildings in a way that reduces the ability of embers to intrude, a major cause of structure ignition is reduced.

Recently adopted building codes reduce the risk of burning embers igniting buildings. Standards are already in effect for roofs, attic vents, siding, exterior doors, decking, windows, eaves, wall vents and enclosed overhanging decks.

Protecting a building from wildfire takes a two-pronged approach:

• Remove flammable materials from around the building
• Construct the building of fire resistant material

The law requires that homeowners do fuel modification to 100 feet (or the property line) around their buildings to create a defensible space for firefighters and to protect their homes from wildfires.

New building codes will protect buildings from being ignited by flying embers which can travel as much as a mile away from the wildfire.  The following ignition-resistant standards are designed to prevent embers from igniting a building:

BUILDING MATERIALS LISTINGS FOR WILDLAND URBAN INTERFACE BUILDING MATERIALS

The Office of the State Fire Marshal's (SFM) Building Materials Listing Program (BML) was originally created to mandate that all fire alarm systems and fire alarm devices be approved and listed by the State Fire Marshal prior to sale or marketing within the state. The program later was expanded to include many other materials such as: roof coverings, fire resistive wall and ceiling-floor assemblies, wall finish materials, fire and non-fire related hardware, insulating products, fire doors, fire dampers, electrical appliances and devices. Each product approval and listing is based upon an evaluation of test results that include an analysis of required product performance and reliability features. All manufacturers that want to list products in California must have those products tested and labeled by a SFM accredited laboratory. If a product does not qualify for listing but meets the standard of the “Materials and Construction Methods for Exterior Wildfire Exposure,” Chapter 7A of the California Building Code will be listed in the WUI Product Handbook.

WUI BUILDING MATERIALS TESTING STANDARDS

• Testing Standards CA SFM 12.7A-1, Exterior Wall Siding and Sheathing
• Testing Standards CA SFM 12.7A-2, Exterior Windows
• Testing Standards CA SFM 12.7A-3, Under Eaves
• Testing Standards CA SFM 12.7A-4, Decking
• State Fire Marshal Building Materials Listing Web Page

The new building standard for the Fire Hazard Severity Zones will be enforced by the Building Official as projects go through the plan checking process. To best assist them in determining if a product meets the code requirements, the State Fire Marshal's BML Program is accepting applications for materials that meet the new code. These materials will be listed on the SFM BML website and the Wildland Urban Interface Building Codes page of the Wildland Hazards and Building Codes website section. The SFM listing service provides building authorities, architectural and engineering communities, contractors, and the fire service with a reliable and readily available source of information.

Since the materials under Wildland Urban Interface Building Codes (except wood shakes and shingles) are not required by law to be listed by the SFM, the listing for these products are strictly voluntary. Materials not listed by the SFM may still qualify for use provided they met all the requirements under Chapter 7A. If not listed on the SFM site, all documentation and testing certificates showing compliance must be submitted to the building official having jurisdiction for final approval.

EFFECTIVE DATES OF CODE:

On September 20, 2007 the Building Standards Commission approved the Office of the State Fire Marshal’s emergency regulations amending the California Code of Regulations (CCR), Title 24, Part 2, known as the 2007 California Building Code (CBC).

“701A.3.2 New Buildings Located in Any Fire Hazard Severity Zone.

A wildfire-safe home must be an ember-ignition-resistant home, so that even if the flames do not reach your home, it will be able to withstand exposure to embers that may have been blown a mile or more in front of a wildfire.  To provide maximum wildfire protection for your home, a combination of near-home vegetation management, appropriate building materials, and related design features must be used. These points are summarized the excellent Univesity of California publication, "Home Survival in Wildfire-Prone Areas: Building Materials and Design Considerations."

Preparing and maintaining adequate defensible space will guard against flame contact and radiant exposures from nearby vegetation—but because of the likely ember exposure to your home during a wildfire, you cannot ignore building material and design considerations. Similarly, if you ignore your defensible space (i.e., you do not have it or do not maintain it), the wildfire will produce maximum ember, flame, and radiant exposures to your home.  It is very unlikely that even hardened buildings can survive such exposure, as a weak link will likely exist somewhere in the building enclosure. 

There is a direct link between home survival, the vegetation management required in developing adequate defensible space around the home, and the building materials and design used to construct the home. The area where your vegetation should be managed (i.e., your defensible space) will depend on the particular topography and siting of the home on the property. Information included in this publication is focused on the home and is intended to provide information to help you make “fire wise” decisions regarding material choices and design decisions, whether you are building a new home or retrofitting your existing house. A considerable amount of information has been published in recent years on defensible space and vegetation management. Check with your local cooperative extension office or fire department for information appropriate to your area.

Hundreds of fires are started each year by power tools.   If you live in a wildland area, use extreme caution during fire season.  Lawn mowers, string trimmers, chain saws, grinders, welders, and tractors can all start fires if not used properly.

Mowing:  Striking  rocks can create sparks  and start fireas in dry grass. Use caution, mow only early in the day (before 10AM, when the weather is calm, cool, and moist). 

Spark Arresters:  In wildland areas, spark arresters are required on all portable, gasoline-powered equipment. This includes  tractors, harvesters, chainsaws, weed-trimmers and mowers.

Keep the exhaust system, spark arresters  and mower in proper working order and free  of carbon buildup.  Use the recommended grade of fuel, and don’t top it off.

From earthquakes and hurricanes to flooding and rising sea levels, natural disasters can strike anywhere and at any time. No region of the country is immune from the impacts and rising costs of disaster damage. In light of this stark reality, the National Building Museum presents a multimedia exhibition titled Designing for Disaster, a call-to-action for citizen preparedness—from design professionals and local decision-makers to homeowners and school kids. The exhibition explores strategies local leaders are currently pursuing to reduce their risks and build more disaster-resilient communities. The exhibition will open May 11, 2014 and remain on view through August 2, 2015.

Natural disasters can impact any of us, anywhere, at any time. In 2012, the financial toll in the United States alone exceeded $100 billion, and the loss of life and emotional toll is immeasurable. No region of the country is immune—112 events in 32 states were declared natural disasters in the U.S. during 2012.

The National Building Museum's exhibition, Designing for Disaster, examines how we assess risks from natural hazards and how we can create policies, plans, and designs yielding safer, more disaster-resilient communities.

Appropriate manipulation of the landscape can make a significant contribution towards wildfire survival.  Firescaping integrates traditional landscape functions and needs into a design that reduces the threat from wildfire.

In addition to meeting a homeowner’s aesthetic desires and functional needs, firescaping includes vegetation modification techniques, planting for fire safety, defensible space principles, and use of fire safety zones.

Three factors determine wildfire intensity:  topography, weather and fuels (vegetation).  Property owners can control the fuel component through proper selection, placement, and maintenance of vegetation.  Careful planning and firescape design can diminish the possibility of ignition, lower fire intensity, and reduce how quickly a fire spreads – all factors which will increase a home’s survivability during a wildfire.  

In firescaping, plant selection is primarily determined by a plant’s ability to reduce the wildfire threat.  Other considerations may be important such as appearance, ability to hold the soil in place, and wildlife habitat value.

Minimize use of evergreen shrubs and trees within 30 feet of a structure, because junipers, other conifers, and broadleaf evergreens contain oils, resins, and waxes that make these plants burn with great intensity.  

Choose “fire smart” plants - typically plants with a high moisture content, larger leaves, low growing, with stems and leaves that are not resinous, oily or waxy.  Deciduous trees are generally more fire resistant than evergreens because they have a higher moisture content when in leaf, and a lower fuel volume when dormant.  

Placement and maintenance of trees and shrubs is as important as actual plant selection.  When planning tree placement remember their size at maturity. Keep tree limbs at least 10 feet from chimneys, power lines and structures, and separate canopies so no trees touch.  Do not plant shrubs beneath trees.

Firescape design uses driveways, lawns, walkways, patios, parking areas, areas with inorganic mulches, and fences constructed of nonflammable materials such as rock, brick, or concrete to reduce fuel loads and create fuel breaks. Fuel breaks are a vital component in firescape design.  While bare ground can not burn, it is not promoted as a firescape element due to aesthetic and soil erosion concerns.

When designing a firesafe landscape, remember that less is better.  Simplify visual lines and groupings.  A firesafe landscape lets plants and garden elements reveal their innate beauty by leaving space between plants and groups of plants.   In firescaping, open spaces are as important as the plants.

Adapted from http://wildfiretoday.com/2014/04/18/the-true-cost-of-wildfire/

A recent conference in Glenwood Springs, Colorado explored The True Cost of Wildfire.

Usually the costs we hear associated with wildfires are what firefighters run up during the suppression phase.  The National Incident Management Situation Report provides those numbers daily for most ongoing large fires. But other costs may be many times the cost of suppression, including the value of structures burned, crops and pastures ruined, economic losses from decreased tourism, medical treatment for the effects of smoke, salaries of law enforcement and highway maintenance personnel, counseling for victims, costs incurred by evacuees, infrastructure damage and shutdowns, rehabilitation of watersheds, forests, flood and debris flow prevention, and repairing damage to reservoirs filled with silt.  And of course there can not be a value placed on the lives that are lost in wildfires.  In Colorado alone, fires since 2000 have killed 8 residents and 12 firefighters.

The total cost of a wildfire can be mitigated by fire-adaptive communities, hazard fuel mitigation, fire prevention campaigns, and prompt and aggressive initial attack of new fires with overwhelming force by ground and air resources. Investments in these areas can save large sums of money. And, it can save lives, something we don’t hear about very often when it comes to wildfire prevention and mitigation; or spending money on adequate fire suppression resources.Below are some excerpts from a report on the conference that appeared in the Grand Junction Sentinel:

[Fire ecologist Robert] Gray said the 2000 Cerro Grande Fire in New Mexico ended up having a total estimated cost of $906 million, of which suppression accounted for only 3 percent.Creede Mayor Eric Grossman said the [West Fork Complex] in the vicinity of that town last summer didn’t damage one structure other than a pumphouse. But the damage to its tourism-based economy was immense.“We’re a three-, four-month (seasonal tourism) economy and once that fire started everybody left, and rightfully so, but the problem was they didn’t come back,” he said.

A lot of the consequences can play out over years or even decades, Gray said.He cited a damaging wildfire in Slave Lake, in Alberta, Canada, where post-traumatic stress disorder in children didn’t surface until a year afterward. Yet thanks to the damage to homes from the fire there were fewer medical professionals still available in the town to treat them.“You’re dealing with a grieving process” in the case of landowners who have lost homes, said Carol Ekarius, who as executive director of the Coalition for the Upper South Platte has dealt with watershed and other issues in the wake of the 2002 Hayman Fire and other Front Range fires.

The Hayman Fire was well over 100,000 acres in size and Ekarius has estimated its total costs at more than $2,000 an acre. That’s partly due to denuded slopes that were vulnerable to flooding, led to silt getting in reservoirs and required rehabilitation work.“With big fires always come big floods and big debris flows,” Ekarius said.Gray said measures such as mitigating fire danger through more forest thinning can reduce the risks.

The 2013 Rim Fire in California caused $1.8 billion in environmental and property damage, or $7,800 an acre, he said.“We can do an awful lot of treatment at $7,800 an acre and actually save money,” he said.Bill Hahnenberg, who has served as incident commander on several fires, said many destructive fires are human-caused because humans live in the wildland-urban interface.“That’s why I think we should maybe pay more attention to fire prevention,” he said.

Just how large the potential consequences of fire can be was demonstrated in Glenwood Springs’ Coal Seam Fire. In that case the incident commander was close to evacuating the entire town, Hahnenberg said. “How would that play (out)?” he said. “I’m not just picking on Glenwood, it’s a question for many communities. How would you do that?” He suggested it’s a scenario communities would do well to prepare for in advance.

The chart below from EcoWest.org shows that federal spending per wildfire has exceeded $100,000 on an annual basis several times since 2002. Since 2008 the cost per acre has varied between $500 and $1,000. These numbers do not include most of the other associated costs we listed above.

1. Equipment Use Safety

• Never mow or trim dry grass on a Red Flag Warning Day. (Mow before 10 a.m. on a day when it’s not hot and windy).
• Never use lawn mowers in dry vegetation.
• Spark arresters are required in wildland areas on all portable gasoline powered equipment.

2. Campfire Safety

• Before starting a campfire, make sure you have a campfire permit and that they are permitted on the land you are visiting.
• Afterwards, ensure that your campfire is properly extinguished.

4. Vehicle

• Never pull over in dry grass.
• Ensure trailer chains don't drag on the ground.
• Make sure your vehicle is properly maintained. 
• Have proper tire pressure to avoid driving on wheel rim.
• Never let your brake pads wear too thin.

  5. Other

• Make sure cigarette butts are properly extinguished.
• Never burn landscape debris like leaves or branches on NO Burn Days or when it's windy or areas where not allowed.
• Target shoot only in approved areas, use lead ammunition only, and never at metal targets.
• Report any suspicious activities to prevent arson.
