Williamson County is part of the
Austin-Round Rock-San Marcos metropolitan statistical area. It was included with Austin in the Best Cities to Live in for 2009 by the
Milken Institute. Located in
Central Texas, it is on both the
Edwards Plateau to the west, rocky terrain and hills, and
Texas Blackland Prairies in the east, rich, fertile farming land. The two areas are roughly bisected by
Interstate 35.
History
Prehistoric

Much of Williamson County has been the site of human habitation for at least 11,200 years. The earliest known inhabitants of the area lived during the late
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was fin ...

Clovis culture around 9,200 BC based on evidence found at Bell County's much-studied Gault Site. One of the most important discoveries in recent times is the ancient skeletal remains dubbed the "Leanderthal Lady" because of its age and proximity to
Leander, Texas. It was discovered by accident by the

workers while drilling core samples for a new highway. The site has been extensively studied for many years, and samples from this site carbon date to the Pleistocene period around 10,500 years ago. Prehistoric and
Archaic "open occupation" campsites are also found throughout the county along streams and other water sources, including
Brushy Creek in Round Rock and the
San Gabriel River in Georgetown. Such evidence of Archaic-period inhabitants is often in the form of relics and flint tools recovered from burned rock middens. Many such sites were inundated when the San Gabriel River was dammed to create Lake Granger.
The earliest known historical Native American occupants, the
Tonkawa, were a flint-working, hunting people who followed the
buffalo on foot and periodically set fire to the prairie to aid them in their hunts. During the 18th century, they made the transition to a horse culture and used firearms to a limited extent. After they were crowded out by white settlement, the
Comanches continued to raid settlements in the county until the 1860s. Also, small numbers of
Kiowa, Yojuane,
Tawakoni, and Mayeye Indians apparently were living in the county at the time of the earliest Anglo settlements.
Thrall flood
On September 9 and 10, 1921, the remnants of a hurricane moved over Williamson County. The center of the storm became stationary over
Thrall, a small farming town in eastern Williamson County, dropping a storm total of of rain in 36 hours. The 24-hour rainfall total ending 7 am on September 10, 1921 () at a U.S. Weather Bureau station in Thrall remains the national official 24-hour rainfall record. Thrall's rainfall was during 6 hours, during 12 hours, and during 18 hours.
Eighty-seven people drowned in and near Taylor, and 93 in Williamson County. This storm caused the most deadly floods in Texas, with a total of 215 fatalities.
1997 tornado outbreak
On May 27, 1997, Williamson County was hit by the worst tornado outbreak in county history. The
1997 Central Texas tornado outbreak caused 20 tornadoes including an F-5 (the strongest rating used for tornadoes on the
Fujita scale

), which remains the only F-5 to strike Williamson County. The F-5 tornado killed 27 people and completely destroyed the Double Creek Estates neighborhood in the city of
Jarrell, Texas, located in far northern Williamson County. Another strong tornado, an F-3, struck
Cedar Park, killing one person. Two F-2 tornadoes also struck Williamson County. The outbreak cost the county over $190 million in damages and a total of 30 fatalities.
Modern growth
Williamson County's fast growth rate is due in large part to its location immediately north of
Austin coupled with Austin's rapid expansion northward; Austin's city limits cross into Williamson County. Most of the growth has been residential, but large employers, such as

's international headquarters, have also changed Williamson County from a bedroom community into a community where citizens can live and work in the same general vicinity. This has transformed the county over recent years into a dynamic, self-sustaining community with less dependency on Austin. Major retail and commercial developments began appearing from 1999 to present, including the Rivery in Georgetown, and the

-area retail, and the
La Frontera mixed-use center in Round Rock. Health care and higher education have also become major factors in the county's growth. Two new colleges and two new hospitals have opened since 2015. Another significant factor has been the opening of the North
Loop 1 and
Texas State Highway 45 toll roads, which have made Williamson County more accessible to Austin.

The area is divided into two regions by the Balcones Escarpment, which runs through the center from north to south along a line from Jarrell to Georgetown to Round Rock. The county's western half is an extension of the Western Plains and considered to be within the eastern fringes of
Texas Hill Country; it has an average elevation of . It features undulating, hilly brushland with an abundance of

. The county's eastern half is part of the Coastal Plains and is flat to gently rolling with an average elevation of . It has dark clay and rich, fertile soils for agriculture, but is quickly being developed as the county's population continues to increase and expand out.
Williamson County is drained in the center and south by the San Gabriel River, the county's only river, and in the north by creeks that run into the Lampasas and Little Rivers north of the county line.
Topography
Williamson County's eastern portion lies within the low-lying prairie areas east of the
Balcones Escarpment (also known as the Balcones Fault, though it is not an
active fault). It begins a piedmont, a foot-friendly fall line of slightly sloping land downward to the coastal area, an area of the
Blackland Prairie consisting of rich, fertile, clay-containing soils, where the land is still used for agriculture, growing cotton and other crops and raising cattle. These prairie lands essentially run from Williamson County to the Gulf Coast, and have a rich heritage of being farmed by German, Polish, and other settlers.
West of the escarpment is the beginning of the "upland" Texas Hill Country, characterized by rocky terrain with thin layers of soil on top of
limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science) ...
. Some ranching occurs in the uplands, but mostly it has been the target of residential development because of the rolling terrain, vistas, hardwood trees, abundant wildlife, and rivers and streams (the same reason early Indians camped in the area). The Hill Country areas are characterized by their porous "vugular" (honeycombed) rock, where rainwater percolates down to replenish the
Edwards Aquifer. For that reason, development restrictions are in place and several endangered species are protected by the

(USFWS).Interstate 35, the county's main artery, runs along the fault line dividing the two distinct regions.
Environmentally protected areas
Balcones Canyonlands National Wildlife Refuge is in the Texas Hill Country northwest of Austin, including parts of western Williamson County. The refuge was formed in 1992 to conserve habitat for two endangered songbirds, the
golden-cheeked warbler and the
black-capped vireo, and to preserve Texas Hill Country habitat for other wildlife species. The refuge augments a similarly named preserve in Austin, the Balcones Canyonlands Preserve. The vegetation found in the Hill Country includes various oaks, elms, and
Ashe juniper trees (often called "cedar" in Texas). The golden-cheeked warbler and black-capped vireo depend on different successional stages of this vegetation, and both nest in the Edwards Plateau, the warbler exclusively so. Some protected areas are open to visitors, such as the
Berry Springs Park.
Endangered species
Williamson County is home to five endangered species. Two are songbirds protected by the Balcones Canyonlands Preserve in
Travis and Williamson Counties. The other three are invertebrate species found only in Williamson County, which live in the cavelike fissures on the west side of the county.

is the name for the honeycomb-type limestone formations (including caves, sinkholes, and fissures) typical of the county's limestone geology west of Interstate 35. In the 1990s, a group of concerned landowners, individuals, and real-estate developers formed the Northern Edwards Aquifer Resource Council with the goal of obtaining a USFWS 10-A permit (known as an
incidental take permit) for the county by identifying and preserving sufficiently many caves with endangered species to ensure survival of the species. These species would be preserved through voluntary donations of land rather than required setbacks, grants, and other involuntary means typically enforced on landowners without an incidental take permit. The group transferred its successful work on an
environmental impact statement to the county in 2002 and a county-wide 10-A permit was obtained in October 2008. Property owners are able to participate in the county's 10-A permit by applying through the WCCF.

Government and politics

Th
Commissioners Courtis the overall governing and management body of Williamson County, and is responsible for all budgetary decisions in addition to setting the tax rate each year. Among its duties is the administration of all county business, including the building and maintenance of county roads and bridges. Commissioners' courts are governing bodies of
county government in several US states, including Texas. The principal functions of the commissioners' court are legislative and executive. Although called courts, commissioners' courts generally exercise only limited judicial powers. The commissioners' court consists of five members. The county judge presides as chairman, and is elected every four years by voters countywide. Four commissioners are elected by single-member precincts every four years.

Sun City Texas
One of the most significant growth factors of modern Williamson County is the location of a new Sun City community in Georgetown. Opened in June 1995, and originally named "Sun City Georgetown",
Sun City Texas is a 5,300-acre (21-km
2) age-restricted community about west of IH-35 on Andice Road (RR 2338). It is part of the chain of Sun City communities started by
Del E. Webb Construction Company (now a division of
PulteGroup). Residency is restricted to persons over age 55 (at least one person in a couple has to be 55 or older) and the community is generally oriented toward retirees.

As originally planned, the project would double the size of Georgetown's population. Sun City Texas is made up mostly of single-family dwellings, but also has duplexes. The Sun City project includes three golf courses (Legacy Hills, White Wing, and Cowan Creek).
Although the community attracts residents from all over, most come from within Texas to stay close to their original homes. Vocal opposition to the project has occurred, especially at the start during the zoning process, with arguments against the size of the community, its effect on Georgetown as a family-oriented town, concerns about the costs of providing city utilities, concern about lowered city and Williamson County property taxes, which are fixed for retirees under Texas law, and the disproportionate effect of city voting.
By and large, though, the community has been welcomed and accepted by the Georgetown populace. In the 2008 city elections, for example, two residents of Sun City were the only candidates for mayor of Georgetown. They also were both formerly elected city council members.
Economy
Agriculture
Williamson County was an agrarian community for most of the 19th and early 20th centuries. Cotton was the dominant crop in the area between the 1880s and the 1920s, and Williamson County was the top producer of cotton in Texas. Primarily to transport bales of cotton, the county was served by two national railroads, the
International-Great Northern Railroad, which eventually merged into the Missouri Pacific, and the
Missouri–Kansas–Texas Railroad. The town of
Taylor in eastern Williamson County became the primary center for cotton production,

ning, and compressing cotton into bales to transport by rail.
Other agriculture activities, farming, and dairying were also a part of rural Williamson County east of the Balcones Fault, and ranching occurred to the west in the Hill Country area. Both gradually gave way to more modern business, services, and retail as the area became more urban, but cattle ranching is still a major business in some areas of the county, and cotton is still a significant crop eastward toward
Hutto and Taylor.

Premium Outlet Mall in Round Rock, as well as those in the La Frontera mixed-use project in Round Rock are significant to the county. Wolf Ranch and The Rivery are also major retail centers in Georgetown. In addition, higher education has a large positive effect on the county with the opening of the Texas State University Campus in Round Rock and the
Austin Community College campus. The Round Rock campus is the single largest campus in the ACC system, providing two-year degrees and training in the high-tech sector, nursing, and other specialties.
County courthouse
The current courthouse, built in 1911, is an example of
Neoclassical Revival architecture. The courthouse has had a tumultuous past, surviving three major renovations and many modifications, including the demolition of its key architectural features in 1966. With the assistance of the Texas Historical Commission and preservation-minded county citizens and officials, the courthouse was returned to its original 1911 state during a major 2006–2007 renovation, once again becoming a focal point of the county.
Flag
The stars on the flag surrounding the state of Texas represent the 33 viable communities identified by Clara Stearns Scarbrough in her 1973 book, ''Land of Good Water''. In 1970, these communities ranged in population from 20 people in Norman's Crossing to more than 10,000 residents in Taylor. Establishing how many communities exist in Williamson County today is difficult, because the determination of "community" is subjective and without set criteria. However, in Williamson County as of 2004, 11 towns had populations over 1,000 people, and seven towns had populations above 5,000.
