The devastating wildfires in Bastrop, Sept. 6, 2011 (Photo by Sandy Carson)
As you learn this, half of Travis County is classed below excessive wildfire danger. Despite this Tuesday’s much-needed storm, the county has been below a burn ban since May 11, the default mode that we reset to each couple of weeks. Whatever the present climate, native emergency managers and elected officers alike proceed to hammer dwelling the identical sentiment: It’s not if, however when, an out-of-control, California-sized wildfire might ravage Central Texas.
But if we get sufficient rain to avert that chance in the long run, a lot of the area – actually, a few of the similar locations with the best wildfire danger – might as a substitute be ravaged by flooding. What does all of it imply? Preparing for doomsday is a full-time job that requires all arms on deck.
What’s a Woo-ee?
In late March, the National Weather Service issued what’s known as a crimson flag warning for the Austin and San Antonio metro areas, indicating elevated wildfire danger because of dry circumstances and excessive winds. Texas, together with different Southwest states, has skilled lengthening periods of drought because of local weather change. According to the metrics utilized by fireplace departments to gauge wildfire danger – a components often called the Energy Release Component that components in each climate circumstances and the quantity of vegetation accessible to gas a wildfire – 2022 has already exceeded all earlier data within the Eastern Hill Country, or the western half of the Austin metro space.
How many individuals and properties are within the path of such a fireplace? A complete lot, not simply in Austin however throughout Texas. According to the chance evaluation firm Verisk, Texas is second solely to California within the variety of properties at risk. Most of those are positioned in what’s known as the wildland-urban interface, or WUI (pronounced “woo-ee”), which is simply what it feels like: the place the town meets the nation. The WUI covers 36% of the land space of the town of Austin and 59% of Travis County; whereas it is totally on the west aspect, it does embrace river and creek bottomlands to the east.
This huge terrain has a lot of brush and vegetation – together with Ashe juniper, or “cedar,” which is exceptionally hazardous when it dries out after which catches fireplace. Embers from such fires can journey as much as a quarter-mile earlier than burning themselves out, which is how a prescribed burn close to Bastrop earlier this yr sparked fires that introduced again painful recollections of the 2011 Labor Day blazes in the identical space, essentially the most damaging in Texas historical past.
The Bastrop County Complex fireplace, because it’s formally recognized, was set off by an influence line knocked down by a tree that was blown down by the excessive winds; in the end, Bluebonnet Electric Cooperative and its tree-trimming vendor ended up settling dozens of lawsuits, together with a $5 million payout to the town, county, and college district for misplaced property worth. In 2019, City Council Member Alison Alter requested an audit of Austin’s wildfire preparedness, which delivered an identical verdict: Austin Energy traces and the timber round them pose the best risk, significantly west of MoPac – in Alter’s District 10 and in Districts 6 and eight to its north and south.
That’s resulted in concrete adjustments being carried out now, Alter advised the Chronicle. The areas of highest danger in D10 must be mitigated by the tip of this yr, and “I’ve been working with [AE] to accelerate that work all across the city,” she mentioned. You might do not forget that a part of the cascade of disasters attributable to Winter Storm Uri in February 2021 likewise concerned downed energy traces on the west aspect, knocked out by ice-heavy tree limbs that left massive components of D10 with out energy (and water) each earlier than and after the blackout attributable to the near-failure of the Texas energy grid.
This interactive map produced by the town permits residents to go looking their tackle to drag up a chart together with their wildfire danger rating, classification and different key preparedness data.
Being Better Builders
Clearing these low-hanging branches is the low-hanging fruit, if you’ll, of wildfire danger administration. The most essential long-term mitigation technique is to undertake particular constructing codes for properties in the WUI, as California has performed statewide starting within the Eighties. In Texas, a statewide mandate would not fly, so it is as much as every locality to determine what to do by itself. Austin was the primary main metropolis in Texas to undertake a neighborhood WUI constructing code, built-in into the Land Development Code in 2020.
Austin Fire Marshal Tom Vocke explains that Austin’s new code is actually extra stringent than WUI guidelines elsewhere; for instance, most WUI codes set up a brush clearing buffer in that quarter-mile “ember zone,” however in Austin that buffer space stretches for a mile and a half. Even with that further room, “[We] opted to not push brush mitigation as a solution, [but] to focus on ignition-resistant construction as our primary means of providing protection, because brush grows back,” Vocke mentioned. “If we can get ignition-resistant construction in place, we know we have 20-30 years of good protection for the home,” mentioned Vocke.
“Ignition-resistant construction” consists of not solely the selection of constructing supplies, however reinforcing doorways, home windows, roofs, and ductwork to maintain embers out and putting in spark arresters on chimneys. (In a lot of California, wood-burning fireplaces are usually not allowed in any respect, each for fireplace danger mitigation and to enhance air high quality.) But these WUI code provisions solely apply to new building; there isn’t a approach to mandate the “hardening” of current houses.
The WUI code additionally addresses evacuation routes, significantly within the many cul-de-sac subdivisions and gated nation membership communities on Austin’s western edge. Alter’s Council colleague Mackenzie Kelly owes her 2020 victory over Jimmy Flannigan to neighbors in a single such group, River Place, who opposed Flannigan’s efforts to allow multifamily density on that one evacuation route. “We will not be able to build additional evacuation routes in communities that are one way in and one way out,” says Alter. “That was defective planning way back. We can be sure that any new developments which can be within the WUI completely have a number of exits.
“We experienced a low-probability high-risk event with Winter Storm Uri,” she continued. “We need to treat wildfire as a high-probability high-risk event. And there is so much more that we need to be doing as a community, city, and county to be prepared to mitigate our risk.”
People Need to Participate
Effective emergency preparedness, whether or not for wildfire or flood or winter storm or the rest, requires the general public to do its half. The National Wildfire Coordinating Group lays out three overarching suggestions for mitigating danger:
1) Restoring and sustaining resilient landscapes.
2) Creating fire-adapted communities.
3) Responding to wildfires successfully.
The WUI code addresses the primary of those. As for the second, Travis County at present has 20 Firewise Communities – a program of the National Fire Protection Association that certifies cities and neighborhoods with a wildfire preparedness plan – out of about 90 in your entire state. They embrace your entire cities of West Lake Hills (since 2008), Lago Vista (since 2011), and Jonestown (since 2012). Another 58 neighborhoods are “engaged” within the technique of turning into Firewise, in accordance with native fireplace officers.
Comanche Trail, overlooking Hippie Hollow alongside Lake Travis, isn’t one in every of these but, however County Commissioner Brigid Shea, whose Precinct 2 consists of the north shore of the lake so far as Volente, cites the neighborhood fire evacuation drill her workplace helped placed on there as a mannequin of group participation. Shea says the county does not have the workers or price range to prepare these drills by itself: “People might say, ‘Why not pick a bigger neighborhood or a more diverse neighborhood?’ Part of it was, a lot of people [out there] were retired, a lot of them had management experience. And they were willing to do it, and they had the time to do it. We leveraged their experience and their leisure time to create this.”
The third prong of preparedness, the precise firefighting response, can be getting a makeover because of Alter’s 2019 name for an audit. Most city fireplace departments, together with Austin’s, practice to answer residential construction fires; they’re unfamiliar with the specialised strategies required for wildfire response, and (once more, not like California) the state does not have the instruments and assets to again them up, wanting deploying the National Guard, who’re even much less effectively skilled.
Austin Fire has had a wildfire division since 2012, nevertheless it’s been centered on public engagement (together with the Firewise program) and gas mitigation – e.g., clearing brush. As a results of Alter’s initiative, for the previous six months your entire Austin Fire Department has been present process Responding to the Interface coaching, a program launched in 2019 with federal funding by the International Association of Fire Fighters, of which the Austin Firefighters Association is Local 975; former AFA Vice President Randy Denzer helped develop and beta-test the coaching, and Austin is the biggest municipal fireplace service within the nation to make use of it as a division. Last yr, AFD created its first wildfire battalion, which can endure much more specialised coaching that might take one other yr or two earlier than it is able to deploy as a primary response.
Much of Travis County’s wildfire danger is concentrated not in areas served by the Austin Fire Department, however by the county’s 14 Emergency Service Districts, every created advert hoc by the state and with its personal guidelines, practices, and codes. “It’s not a perfect setup,” says County Commissioner Brigid Shea.
But Beyond the City Limits …
Unlike Austin’s Emergency Medical Services Department, Austin Fire doesn’t function countywide, nor does Travis County have its personal fireplace division to work with AFD the best way the Travis County Sheriff’s Office works with Austin police. Much of the WUI lies throughout the domains of 14 separate emergency providers districts, or ESDs, created by the Texas Legislature through the years to bridge this hole and now typically “their own fiefdoms,” as Shea places it. “They have their own fire chiefs, their own taxing authorities, and neither the counties nor the cities can tell them what to do, really.”
Some of the ESDs overlap. Some are noncontiguous, resembling ESD 4, served by AFD by interlocal settlement and together with random bits of the Austin fringe north of the river, from Jester Estates within the west to Hornsby Bend within the east. Some embrace cities that do not have their very own fireplace departments, resembling Pflugerville. Some have their very own fireplace codes. “It’s not a perfect setup,” Shea mentioned understatedly, “to have all the wildfire response for a large urban county that has a very high wildfire rating to be managed by 14 independent fire districts.”
Austin does, nonetheless, management 911 dispatch for your entire county, and AFD has opted into automatic-aid agreements with all of the Travis County ESDs and a few in Williamson County as effectively, that means if Austin’s fireplace stations or gear are closest to a fireplace, AFD will reply first. However, citing variations with how AFD is run, Hutto (WilCo ESD 3), Pflugerville (Travis ESD 2), and Manor (Travis ESD 12) have opted out of those auto-aid agreements. “If they had a large brush fire, we would not automatically send units over into Pflugerville,” says AFD Assistant Chief of Operations Brandon Wade. While the division is contemplating providing RTI coaching to the ESDs, proper now, mentioned Wade, “We’re trying to get our own members through the program, and it’s going to take quite some time.”

What About the Floods?
Before the Bastrop County Complex fireplace in 2011 – and a simultaneous blaze in Steiner Ranch, west of River Place, that was a lot much less damaging however equally scary – most Austinites did not assume that a lot about their fireplace danger. They are effectively conscious, nonetheless, of the other danger right here in Flash Flood Alley, the one sort of pure disaster Austin encounters usually and really destructively.
Kevin Shunk, floodplain administrator for the town of Austin and its liaison with the National Flood Insurance Program run by the Federal Emergency Management Agency, says not like wildfire danger, which is widespread however not in every single place, “flood risk is spread throughout the entire city. It’s all over the place. There are certainly areas that are higher-risk, comparing the two geologic parts of the city, with the east side of Austin being more of a flatland [with a] wider floodplain.” Shunk’s job is to establish flood dangers to evaluate, devise tasks to mitigate them, and assist with group outreach and training. He says the principle “tools in his toolbox” to mitigate danger are buyouts of high-risk neighborhoods and maintaining with stormwater infrastructure, which is the job of Shunk’s Watershed Protection Department.
The highest-profile buyouts have been within the Onion Creek watershed, Austin’s largest. After disastrous floods in 2013 and 2015 (every time on Halloween), the town bought more than 800 properties within the watershed, significantly at its jap finish close to the place Onion Creek enters the Colorado. “But that doesn’t mean that we favor that alternative over any other,” mentioned Shunk. Watershed Protection additionally builds detention ponds to “hold water such that the downstream system can handle [it, and] reduce the rate that it’s going to flow downstream.” One such regional pond is being constructed at Baker School in Hyde Park, now the headquarters of the Alamo Drafthouse.
New developments are additionally required to put in stormwater detention “to make sure they’re not flooding their neighbors, basically,” mentioned Shunk. As for current neighborhoods, and as with the WUI code, older areas like Tarrytown that had been constructed earlier than the floodplain rules haven’t got this infrastructure; the foundations would solely kick in on properties which can be being rezoned or subdivided. “When an individual lot redevelops, if they’re just putting a house on the same lot,” Shunk mentioned, “they would not have to put detention on that property” – even when the brand new home is way greater and will increase impervious cowl on the lot, and thus the chance of downstream flooding.
Floodplain rules additionally require secure entry: “You have to be able to walk from a building to the right-of-way [i.e., the nearest street], all at an elevation at least one foot above the 100-year floodplain,” Shunk mentioned, which helps each residents and responders in an evacuation state of affairs. The metropolis’s emergency managers will ask Watershed Protection, “‘How high is the water going to get and where’s it gonna go? And how long is it going to be at that elevation?’ That would help them plan for an evacuation.”
A brand new statewide flood planning course of initiated by the Texas Legislature is mapping flood areas throughout Texas with the enter of native specialists like these at Watershed Protection. The ensuing plan might unlock funds for danger discount tasks wanted in Austin alongside Shoal and Waller creeks and alongside the misleadingly named Dry Creek in Highland Hills in Alter’s D10, in addition to extra citywide infrastructure and buyouts. “We’ll have a list of projects, and that can hopefully help to plan on possible funding,” mentioned Shunk.
Both flood and fireplace danger are elevated by the Austin space’s increase, as we proceed to construct nearer to the WUI and the 100-year floodplain and climate turns into extra unpredictable because of local weather change. Risk mitigation due to this fact is shared throughout all of Austin’s communities, whether or not we prefer it or not. “We need to step up and be prepared for a totally different kind of disaster planning,” mentioned Alter. “One where we can’t just call on our neighbor next door to help us. We have to make sure that we have resilience within our community, within our system. So that we survive whatever comes our way.”
