Austin is located in south-central Lander County on US Highway 50, almost at the geographic center of Nevada. Based on the risk assessment Austin was assigned to the High Hazard Category (62 points). A summary of factors that contributed to the hazard rating is included in Table 6-3. The high rating was attributed primarily to fire behavior related to topography, aspect, fuels, and poor defensible space. Additionally, numerous vacant lots in town are occupied by decadent stands of sagebrush and associated fuels that could cause a wildfire ignition from within the community.
The wildland-urban interface area around Austin is characterized as an intermixed condition. There is no clear line of demarcation between structures in the community and wildland fuels. The majority of residences are on lots of one acre or less indicating a high density of houses.
Ninety-six percent of the structures observed in the interface were built with non-combustible or highly ignition resistant siding materials such as medium density fiberboard, and 98 percent of the homes had fire resistant roofing materials such as composition, tile, or metal. Twenty-one percent of the homes observed had unenclosed balconies, porches, decks, or other architectural features that create drafts and provide areas where sparks and embers can be trapped, smolder, and ignite, rapidly spreading fire to the home.
Only 48 percent of the homes surveyed in Austin had landscaping that met the minimum standard for defensible space.
Fire protection in Austin consists of an all-volunteer department of eleven volunteers. Additional resources are available from the Bureau of Land Management Battle Mountain and Winnemucca Field Offices, the US Forest Service Austin Ranger District, and the Nevada Division of Forestry Carlin Conservation Camp. Table 6-1 lists the types of wildfire resources, cooperating partners and equipment potentially available to Austin to respond to a reported wildland fire. It is important to note that the actual number and type of suppression resources available to respond from neighboring fire departments and agencies is dependent upon the resources on hand at the time of the wildland fire call.

Water availability for fire suppression in Austin includes:
The water system operates on gravity and electric pumps. There is no backup source of power in the case of power failure during a wildfire.
Austin has a community siren to warn residents of emergencies. In addition to this notification system the Austin Volunteer Fire Department has a lightning plan that assigns volunteers to lookout posts on high hazard lightning days during the fire season. Fires are reported through 911 calls to the Lander County Sheriff’s Office. Fires are communicated to local fire response personnel by the Lander County Sheriff’s Office using radios and pagers. Fires are communicated to federal agency fire personnel by the Central Nevada Interagency Dispatch Center. Nevada Division of Forestry fire crews are dispatched from the Sierra Front Interagency Dispatch Center or the Elko Interagency Dispatch Center.
The Austin Volunteer Fire Department provides fire protection to the community of Austin. The Austin VFD volunteers receive training to meet State Fire Marshal minimum standards for Entry Level Firefighter, and Firefighter I and II. The Austin VFD does not utilize the Red Card system. Red Card certification is part of a fire qualifications management system used by many state and all federal wildland fire management agencies. This certification indicates that an individual is qualified to fight wildland fires. Federal agency fire suppression personnel receive training to meet National Wildfire Coordinating Group standards.
The Austin VFD responded to 125 calls in 2003. Twelve of these were wildland/ brush fire calls.
The Austin VFD receives funding from the Lander County General Fund.
Lander County has an active Local Emergency Planning Committee and has adopted an all-risk emergency plan that includes disaster and hazardous materials handling plans. Austin has its own pre-attack plan for fire incidents.
Austin is located in a narrow east/west canyon. Numerous steep drainages extend directly into the west end of town. The predominant wind is from the west/southwest in the afternoon. Fuel hazard mapping was reviewed for Austin and the community was found to have high and extreme fuel hazards surrounding the community boundary. Fuel hazard mapping is provided in Figure 6-2 and Fuel type Photo Points and conditions are provided in Figure 6-4.
The existing fuel conditions around Austin are conducive to crown fires or high intensity surface fires. Sagebrush and rabbitbrush have recovered in the 1981-burned area east of Austin with cheatgrass, crested wheatgrass, needleandthread grass, and bluegrass providing nearly continuous ground fuel conditions estimated at one to two tons per acre. Drainages contain dense pinyon-juniper stands estimated at eight or more tons per acre. Steep slopes and the prevailing wind direction may reduce fire suppression effectiveness.
A bulk fuel tank storage area, located west of Austin, near the arena, is of considerable concern. Dense fuels estimated at five to six tons per acre adjacent to the tanks are littered with abandoned barrels of unknown origin and old tires. A wildfire carried through this area could create intense heat and smoke and potential tank explosions. (See Figure 6-4 Photo Point 2.)
The worst-case wildland fire scenario for Austin would occur late on a summer afternoon and would begin west of the community. An ignition in the pinyon-juniper stands in any one of the numerous drainages could lead to an intense crown fire, and winds from the west/southwest would create a chimney effect, drawing the fire directly into town. The rate of spread could reach 2,500 to 4,000 feet per hour with flame lengths of fifty to seventy feet. There is a high risk for structure loss if the fire was pushed into the community given the heavy vegetation that occurs in close proximity to structures. The fuel storage tank area west of town poses an additional threat. The tanks (which appear to hold heating oil, gasoline, and diesel) could explode. In addition to fire spreading into the town, winds would push toxic fumes and smoke into the residential areas.
Based on previous fire history, topography, and fuel type, Austin has a high risk of ignition. The area is prone to thunderstorms in the summer and dry lightning is a major cause of ignitions.
In August of 2003, the Bureau of Land Management Battle Mountain Field Office completed an Environmental Assessment for the Wildland Urban Interface/Fire Defense Systems Austin and Kingston, Nevada. The BLM plans include fuel reduction treatments on a total of 2,300 acres around Austin. In 2003 and 2004, BLM completed greenstrips on approximately 1,000 acres (see Figure 6-3). In general, greenstrips ranged between thirty and fifty feet in width with small strips of native vegetation left between each greenstrip. Greenstrip locations and widths varied depending upon topography, fuel types, and presence of cultural resources. Mechanical equipment was used to masticate the shrubs, which left the shredded mulch on the ground, effectively redistributing the fuels. Seeding with fire-resistant species including forage kochia, wildrye, wheatgrass and some native species was also completed on approximately 1,000 acres. Another 1,000 acres are scheduled to be completed in 2005. Fifty acres of pinyon and juniper thinning has been completed with an additional 50 acres to be completed in 2005. Either high intensity, low-frequency grazing, or other managed grazing will be used to maintain the greenstrips if the fuel load of the treatment area ever exceeds 700 pounds per acre.
Risk reduction recommendations for Austin focus primarily on efforts that can be taken by community members and public agencies to increase defensible space, continue to construct and maintain fuels reduction treatments around the community, and increased water storage for helicopter access during wildfire events. Other recommendations pertain to community coordination and public education efforts that could be undertaken to enhance fire safety in Austin.
Vegetation density, type of fuel, and slope gradient around a home affect the potential fire exposure levels to the home. The goals of defensible space are to reduce the risk of property loss from wildfire by eliminating flammable vegetation near the home; thereby, lowering the potential to burn and providing firefighters a safer working area to defend the home or outbuilding during a wildland fire. Guidelines for improving defensible space around residences and structures in the community are given below and are described in detail in Appendix E.
Permanently reducing the fuel structure and fuel volume over large, continuous blocks of land reduces the risk of a catastrophic wildfire and increases firefighter safety. Theridgelines north and south of Austin provide opportunities to create fuelbreaks or greenstrips to effectively slow an advancing wildfire approaching from the north or south and provided firefighters a safe area for fire suppression.
Many of the most effective activities aimed at reducing the threat of wildfire for the Austin community require that individual property owners coordinate with each other and with local fire authorities. Public education and awareness, neighbors helping neighbors, and proactive individuals setting examples for others to follow are just some of the approaches that will be necessary to meet the fire safe goals in the community.
