context_page_description: San Antonio, officially the City of San Antonio, is the seventh-most populous city in the United States, and the second-most populous city in both Texas and the Southern United States, with 1,547,253 residents in 2019. Founded as a Spanish mission and colonial outpost in 1718, the city became the first chartered civil settlement in present-day Texas in 1731. The area was still part of the Spanish Empire, and later of the Mexican Republic. It is the state's oldest municipality, having celebrated its 300th anniversary on May 1, 2018.
  The city's deep history is contrasted with its rapid growth over the past few decades. It was the fastest-growing of the top ten largest cities in the United States from 2000 to 2010, and the second from 1990 to 2000. Straddling the regional divide between South and Central Texas, San Antonio anchors the southwestern corner of an urban megaregion colloquially known as the "Texas Triangle". The Greater San Antonio and Greater Austin areas are separated from each other by 80 miles along Interstate 35.
  San Antonio serves as the seat of Bexar County; San Antonio is the center of the San Antonio–New Braunfels metropolitan statistical area.
context_section_description: Unlike most large cities in the U.S., San Antonio is not completely surrounded by independent suburban cities, and under Texas state law it exercises extraterritorial jurisdiction (ETJ) over much of the surrounding unincorporated land, including planning major thoroughfares and enforcing rules for platting and subdivision. It pursues an aggressive annexation policy and opposes the creation of other municipalities within its ETJ. Nearly three-fourths of its land area has been annexed since 1960.
  In the 2000s the city annexed several long narrow corridors along major thoroughfares in outlying areas to facilitate eventual annexation of growth developing along the routes. The city planned to annex nearly 40 additional square miles by 2009. In May 2010, the City of San Antonio agreed to release thousands of acres of land in its extraterritorial jurisdiction along Interstate 10 to Schertz. The agreement releases a total of 3,486 acres (14.11 km²) of San Antonio's ETJ lands north of I-10 to Schertz. The ETJ lands are in an area bordered by FM 1518 to the west, Lower Seguin Road to the north, Cibolo Creek to the east and I-10 to the south.
  Involuntary annexation is a controversial issue in those parts of unincorporated Bexar County affected by it. Residents attracted to the outlying areas by lower taxes and affordable real estate values often see annexation as a mechanism to increase property tax rates (which are primarily driven by school district taxes, not city taxes) without a corresponding improvement in services such as police and fire protection, while the city regards its annexation policy as essential to its overall prosperity.
  Since the city has annexed areas over time, San Antonio surrounds several independent enclave cities, including Alamo Heights, Balcones Heights, Castle Hills, Hill Country Village, Hollywood Park, Kirby, Leon Valley, Olmos Park, Shavano Park, Terrell Hills, and Windcrest. These are not districts of the City of San Antonio like Lincoln Heights and Brackenridge Park but independent cities in the San Antonio region completely surrounded, but not directly controlled, by the City of San Antonio.
