Austin, Texas

**Austin** is the capital of the U.S. state of Texas and the seat of Travis County, with portions extending into Hays and Williamson counties. It is the 11th-most populous city in the United States and the 4th-most populous city in Texas. It is the fastest growing large city in the United States and the second most populous state capital in the U.S after Phoenix, Arizona. Its population in 2010 was 815,587. Located in Central Texas in the foothills of Texas Hill Country, the city is home to numerous lakes, rivers, and waterways including Lady Bird Lake, Barton Springs, McKinney Falls, the Colorado River, Lake Travis, and Lake Walter E. Long.

In the 1830s, pioneers began to settle the area in central Austin along the Colorado River. In 1839, the site was officially chosen to replace Houston as the new capital of the Republic of Texas and was incorporated under the name Waterloo. Shortly thereafter, the name was changed to Austin in honor of Stephen F. Austin, the "Father of Texas" and the republic's first secretary of state. The city subsequently grew throughout the 19th century and became a center for government and education with the construction of the Texas State Capitol and the University of Texas at Austin. After a lull in growth from the Great Depression, Austin resumed its development into a major city and, by the 1980s, it emerged as a center for technology and business. A number of Fortune 500 companies have headquarters or regional offices in Austin, including Amazon.com, Apple Inc., Cisco, eBay, Google, IBM, Intel, Oracle Corporation, Paypal, Texas Instruments, 3M, and Whole Foods Market.Dell's worldwide headquarters is located in nearby Round Rock, a suburb of Austin.

Residents of Austin are known as Austinites. They include a diverse mix of government employees, college students, musicians, high-tech workers, blue-collar workers, and a vibrant LGBT community. The city's official slogan promotes Austin as "The Live Music Capital of the World," a reference to the many musicians and live music venues within the city, as well as the long-running PBS TV concert series Austin City Limits. The city also adopted "Silicon Hills" as a nickname in the 1990s due to a rapid influx of technology and development companies. In recent years, some Austinites have also adopted the unofficial slogan "Keep Austin Weird," which refers to the desire to protect small, unique, and local businesses from being overrun by large corporations. In the late 19th century, Austin was known as the "City of the Violet Crown" because of the colorful glow of light across the hills just after sunset. Even today, many Austin businesses use the term "Violet Crown" in their name. Austin is known as a "clean-air city" for its stringent no-smoking ordinances that apply to all public places and buildings, including restaurants and bars. The FBI ranked Austin as the second-safest major city in the U.S. for the year 2012. U.S. News & World Report named Austin the best place to live in the U.S. in 2017.

## Geography

The most southerly of the capitals of the contiguous forty-eight states, Austin is located in Central Texas, along the Balcones Escarpment and Interstate 35, 150 miles (240 kilometres) northwest of Houston. It is also 160 miles (260 kilometres) south of Dallas and 75 miles (121 kilometres) north of San Antonio. Its elevation varies from 425 feet (130 m) to approximately 1,000 feet (305 m) above sea level. In 2010, the city occupied a total area of 271.8 square miles (704 km2). Approximately 6.9 square miles (18 km2) of this area is water.

Austin is situated on the Colorado River, with three man-made (artificial) lakes within the city limits: Lady Bird Lake (formerly known as Town Lake), Lake Austin (both created by dams along the Colorado River), and Lake Walter E. Long that is partly used for cooling water for the Decker Power Plant. Mansfield Dam and the foot of Lake Travis are located within the city's limits. Lady Bird Lake, Lake Austin, and Lake Travis are each on the Colorado River. As a result of its straddling the Balcones Fault, much of the eastern part of the city is flat, with heavy clay and loam soils, whereas, the western part and western suburbs consist of rolling hills on the edge of the Texas Hill Country. Because the hills to the west are primarily limestone rock with a thin covering of topsoil, portions of the city are frequently subjected to flash floods from the runoff caused by thunderstorms. To help control this runoff and to generate hydroelectric power, the Lower Colorado River Authority operates a series of dams that form the Texas Highland Lakes. The lakes also provide venues for boating, swimming, and other forms of recreation within several parks on the lake shores.

Austin is located at the intersection of four major ecological regions, and is consequently a temperate-to-hot green oasis with a highly variable climate having some characteristics of the desert, the tropics, and a wetter climate. The area is very diverse ecologically and biologically, and is home to a variety of animals and plants. Notably, the area is home to many types of wildflowers that blossom throughout the year but especially in the spring, including the popular bluebonnets, some planted in an effort by "Lady Bird" Johnson, wife of former President Lyndon Johnson.

## Downtown Austin

In 2005, then-Mayor Will Wynn set out a goal of having 25,000 people living Downtown by 2015. Although Downtown's growth did not meet this goal, Downtown's residential population did surge from an estimated 5,000 in 2005 to 12,000 in 2015. The skyline has drastically changed in recent years, and the residential real estate market has remained relatively strong.

Downtown growth has been aided by the presence of a popular live music and nightlife scene, museums, restaurants, and Lady Bird Lake, considered one of the city's best recreational spots. The 2nd Street District consists of several new residential projects, restaurants, upscale boutiques and other entertainment venues, as well as Austin's City Hall. Across 2nd Street from Austin's City Hall is the new ACL Live @ the Moody Theatre where the long-running PBS program Austin City Limits, is filmed. The South by Southwest (SXSW) is a music, film and interactive festival which occurs over five days each March in downtown Austin, and includes one of the world's largest music festivals; with more than 3,000 acts playing in more than 100 venues.

## Climate

Under the Köppen climate classification, Austin has a humid subtropical climate. This climate is typified by very long, hot summers; short, mild winters; and warm transitional seasons in between. Austin averages 34.32 inches (872 mm) of annual rainfall and it is distributed mostly evenly throughout the year, though spring and fall are the wettest seasons. Sunshine is abundant during all seasons, with 2,650 hours, or 60.3% of the possible total, of bright sunshine per year.

The summer season in Austin is very hot, and average July and August highs frequently reach the high-90s (34–36 °C) or above. Highs reach 90 °F (32 °C) on 116 days per year, of which 18 days reach 100 °F (38 °C). The daytime high averages 80 °F (27 °C) or warmer every day between April 14 and October 24.[72] The highest ever recorded temperature was 112 °F (44 °C) occurring on September 5, 2000, and August 28, 2011. Humidity is inconsistent and fluctuates frequently depending on the shifting patterns of air flow and wind direction. Humidity rises when the air drifts inland from the Gulf of Mexico, but decreases significantly when the air is channeled through the Chihuahuan Desert of West Texas.

Winters in Austin are mild with cool nights. January is the coolest month with an average daytime high of 61 °F (16 °C). The overnight low reaches or exceeds freezing 19 times per year,[71] and sinks below 45 °F (7 °C) during 88 evenings per year, including most nights between mid-December and mid-February. Lows in the upper 30s also occur commonly during the winter. Conversely, winter months are also capable of occasionally producing warm days. On average, eight days in January reach or exceed 70 °F (21 °C) and one day reaches 80 °F (27 °C). The lowest ever recorded temperature in the city was −2 °F (−19 °C) on January 31, 1949. Roughly every two years Austin experiences an ice storm that freezes roads over and cripples travel in the city for 24 to 48 hours. When Austin received 0.04 inches (1 mm) of ice on January 24, 2014, there were 278 vehicular collisions. Similarly, snowfall is exceptionally rare in Austin. A snow event of 0.9 inches (2 cm) on February 4, 2011, caused more than 300 car crashes. A 13-inch (33 cm) snowstorm brought the city to a near standstill in 1985.

Typical of Central Texas, severe weather in Austin is a threat that can strike during any season. However, it is most common during the spring. According to most classifications, Austin lies within the extreme southern periphery of Tornado Alley, although many sources place Austin outside of Tornado Alley altogether. Consequently, tornadoes strike Austin less frequently than areas farther to the north. However, severe weather and/or supercell thunderstorms can occur multiple times per year, bringing damaging winds, lightning, heavy rain, and occasional flash flooding to the city. The deadliest storm to ever strike city limits was the twin tornadoes storm of May 4, 1922, while the deadliest tornado outbreak to ever strike the metro area was the Central Texas tornado outbreak of May 27, 1997.

### 2011 Drought

The 2011 Texas drought dried up much of Central Texas water ways. From October 2010 through September 2011, both major reporting stations in Austin, Camp Mabry and Bergstrom Int'l, had the least rainfall of a water year on record, receiving less than a third of normal precipitation. This was a result of La Niña conditions in the eastern Pacific Ocean where water was significantly cooler than normal. David Brown, a regional official with the National Oceanic and Atmospheric Administration, has explained that "these kinds of droughts will have effects that are even more extreme in the future, given a warming and drying regional climate."
