Houston
Houston ( ) is the most populous city in the state of Texas and the fourth-most populous city in the United States. With a census-estimated 2016 population of 2.303 millionAmerican Fact FinderU.S. Census Bureau within an area of , it is also the largest city in the southern United States and the seat of Harris County. Located in Southeast Texas near the Gulf of Mexico, it is the principal city of the Greater Houston metro area, which is the fifth-most populated MSA in the United States.

Houston was founded on August 28, 1836, near the banks of Buffalo Bayou (now known as Allen's Landing) and incorporated as a city on June 5, 1837. The city was named after former General Sam Houston, who was president of the Republic of Texas and had commanded and won at the Battle of San Jacinto  east of where the city was established. The burgeoning port and railroad industry, combined with oil discovery in 1901, has induced continual surges in the city's population. In the mid-20th century, Houston became the home of the Texas Medical Center—the world's largest concentration of healthcare and research institutions—and NASA's Johnson Space Center, where the Mission Control Center is located.1-B898-0C424A311C28/0/50YearMasterPlanLowRes2006UpdateV2.pdf Texas Medical Center.

Houston's economy has a broad industrial base in energy, manufacturing, aeronautics, and transportation. Leading in health care sectors and building oilfield equipment, outside of New York City, Houston has more Fortune 500 headquarters than any other U.S. municipality within its city limits.Fortune 500 2010: Cities Accessed May 25, 2011 The Port of Houston ranks first in the United States in international waterborne tonnage handled and second in total cargo tonnage handled. Nicknamed the "Space City", Houston is a global city, with strengths in business, international trade, entertainment, culture, media, fashion, science, sports, technology, education, medicine, and research. The city has a population from various ethnic and religious backgrounds and a large and growing international community. Houston is the most diverse city in Texas and has been described as the most racially and ethnically diverse major metropolis in the U.S. It is home to many cultural institutions and exhibits, which attract more than 7 million visitors a year to the Museum District. Houston has an active visual and performing arts scene in the Theater District and offers year-round resident companies in all major performing arts." ", Greater Houston Partnership.

History

thumb|left|upright|Sam Houston
In August 1836, two real estate entrepreneurs from New York, Augustus Chapman Allen and John Kirby Allen, purchased  of land along Buffalo Bayou with the intent of founding a city. The Allen brothers decided to name the city after Sam Houston, the popular general at the Battle of San Jacinto, who was elected President of Texas in September 1836. The great majority of slaves in Texas came with their owners from the older slave states. Sizable numbers, however, came through the domestic slave trade. New Orleans was the center of this trade in the Deep South, but slave dealers were in Houston. Thousands of enslaved African Americans lived near the city before the Civil War. Many of them near the city worked on sugar and cotton plantations, while most of those in the city limits had domestic and artisan jobs.
Houston was granted incorporation on June 5, 1837, with James S. Holman becoming its first mayor. In the same year, Houston became the county seat of Harrisburg County (now Harris County) and the temporary capital of the Republic of Texas. In 1840, the community established a chamber of commerce in part to promote shipping and waterborne business at the newly created port on Buffalo Bayou.John Perry, "Born on the Bayou: city's murky start" , City Savvy Online Edition. Published Summer 2006. Retrieved on February 6, 2007.

By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton. Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont. During the American Civil War, Houston served as a headquarters for General John Bankhead Magruder, who used the city as an organization point for the Battle of Galveston. After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas.

In 1900, after Galveston was struck by a devastating hurricane, efforts to make Houston into a viable deep-water port were accelerated.J.H.W. Stele to Sayers, September 11–12, 1900. Texas State Library & Archives Commission, Retrieved on August 31, 2007 The following year, the discovery of oil at the Spindletop oil field near Beaumont prompted the development of the Texas petroleum industry. In 1902, President Theodore Roosevelt approved a $1 million improvement project for the Houston Ship Channel. By 1910, the city's population had reached 78,800, almost doubling from a decade before. African Americans formed a large part of the city's population, numbering 23,929 people, which was nearly one-third of the residents.

President Woodrow Wilson opened the deep-water Port of Houston in 1914, seven years after digging began. By 1930, Houston had become Texas' most populous city and Harris County the most populous county. In 1940, the Census Bureau reported Houston's population as 77.5% white and 22.4% black.

When World War II started, tonnage levels at the port decreased and shipping activities were suspended; however, the war did provide economic benefits for the city. Petrochemical refineries and manufacturing plants were constructed along the ship channel because of the demand for petroleum and synthetic rubber products by the defense industry during the war. Ellington Field, initially built during World War I, was revitalized as an advanced training center for bombardiers and navigators. The Brown Shipbuilding Company was founded in 1942 to build ships for the U.S. Navy during World War II. Due to the boom in defense jobs, thousands of new workers migrated to the city, both blacks and whites competing for the higher-paying jobs. President Roosevelt had established a policy of nondiscrimination for defense contractors, and blacks gained some opportunities, especially in shipbuilding, although not without resistance from whites and increasing social tensions that erupted into occasional violence. Economic gains of blacks who entered defense industries continued in the postwar years."Race, Roosevelt, and Wartime Production: Fair Employment in World War II Labor Markets", William J. Collins, The American Economic Review, Vol. 91, No. 1 (March 2001), pp. 272–286, Published by: American Economic Association, Stable URL: http://www.jstor.org/stable/2677909

In 1945, the M.D. Anderson Foundation formed the Texas Medical Center. After the war, Houston's economy reverted to being primarily port-driven. In 1948, the city annexed several unincorporated areas, more than doubling its size. Houston proper began to spread across the region.

In 1950, the availability of air conditioning provided impetus for many companies to relocate to Houston, where wages were lower than the North; this resulted in an economic boom and produced a key shift in the city's economy toward the energy sector."How Air Conditioning Changed America", The Old House Web, Retrieved on April 4, 2007"A Short History" , Houston Geological Auxiliary, Retrieved on April 4, 2007 thumb|Ashburn's Houston City Map ()

The increased production of the expanded shipbuilding industry during World War II spurred Houston's growth, as did the establishment in 1961 of NASA's "Manned Spacecraft Center" (renamed the Lyndon B. Johnson Space Center in 1973). This was the stimulus for the development of the city's aerospace industry. The Astrodome, nicknamed the "Eighth Wonder of the World", opened in 1965 as the world's first indoor domed sports stadium.

During the late 1970s, Houston had a population boom as people from the Rust Belt states moved to Texas in large numbers. The new residents came for numerous employment opportunities in the petroleum industry, created as a result of the Arab oil embargo. With the increase in professional jobs, Houston has become a destination for many college-educated persons, including African Americans in a reverse Great Migration from northern areas.

In 1997, Houstonians elected Lee P. Brown as the city's first African American mayor.

In June 2001, Tropical Storm Allison dumped up to  of rain on parts of Houston, causing the worst flooding in the city's history. The storm cost billions of dollars in damage and killed 20 people in Texas. By December of that same year, Houston-based energy company Enron collapsed into the third-largest ever U.S. bankruptcy during an investigation surrounding fabricated partnerships that were allegedly used to hide debt and inflate profits.

In August 2005, Houston became a shelter to more than 150,000 people from New Orleans, who evacuated from Hurricane Katrina. One month later, about 2.5 million Houston-area residents evacuated when Hurricane Rita approached the Gulf Coast, leaving little damage to the Houston area. This was the largest urban evacuation in the history of the United States.8th Congressional District of Texas 2007 Appropriations Project Requests . Congressman Kevin Brady, 8th District of Texas. Retrieved on January 10, 2007. In September 2008, Houston was hit by Hurricane Ike. As many as 40% refused to leave Galveston Island because they feared the type of traffic problems that had happened after Hurricane Rita.

During the floods in 2015 and 2016, parts of the city were covered in several inches of water.

In 2017, Houston hosted Super Bowl LI. This is the third Super Bowl for the city, with the last games being held in 1974 and 2004.

Houston has four major bayous passing through the city. Buffalo Bayou runs through downtown and the Houston Ship Channel, and has three tributaries: White Oak Bayou, which runs through the Houston Heights community northwest of Downtown and then towards Downtown; Brays Bayou, which runs along the Texas Medical Center; and Sims Bayou, which runs through the south of Houston and downtown Houston. The ship channel continues past Galveston and then into the Gulf of Mexico.

Geology
Houston is essentially swampland, prone to flooding. Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.Harris County. Handbook of Texas Online.

No significant historically recorded earthquakes have occurred in Houston, but researchers do not discount the possibility of such quakes having occurred in the deeper past, nor occurring in the future. Land in some areas southeast of Houston is sinking because water has been pumped out of the ground for many years. It may be associated with slip along the faults; however, the slippage is slow and not considered an earthquake, where stationary faults must slip suddenly enough to create seismic waves.Texas Earthquakes, University of Texas Institute for Geophysics, July 2001. Retrieved on August 29, 2007. These faults also tend to move at a smooth rate in what is termed "fault creep", which further reduces the risk of an earthquake.

Climate

Houston's climate is classified as humid subtropical (Cfa in the Köppen climate classification system), typical of the lower South. While not located in "Tornado Alley", like much of the rest of Texas, spring supercell thunderstorms sometimes bring tornadoes to the area. Prevailing winds are from the south and southeast during most of the year, which bring heat and moisture from the nearby Gulf of Mexico.

During the summer, temperatures commonly reach over , with an average of 106.5 days per year, including a majority from June to September, with a high of  or above and 4.6 days at or over .

Cityscape

Houston was incorporated in 1837 under the ward system of representation. The ward designation is the progenitor of the 11 current-day geographically oriented Houston City Council districts. Locations in Houston are generally classified as either being inside or outside the Interstate 610 Loop. The inside encompasses the central business district and many residential neighborhoods that antedate World War II. More recently, high-density residential areas have been developed within the loop. The city's outlying areas, suburbs, and enclaves are located outside of the loop. Beltway 8 encircles the city another  farther out.

Though Houston is the largest city in the United States without formal zoning regulations, it has developed similarly to other Sun Belt cities because the city's land use regulations and legal covenants have played a similar role. Regulations include mandatory lot size for single-family houses and requirements that parking be available to tenants and customers. Such restrictions have had mixed results. Though some have blamed the city's low density, urban sprawl, and lack of pedestrian-friendliness on these policies, the city's land use has also been credited with having significant affordable housing, sparing Houston the worst effects of the 2008 real estate crisis. The city issued 42,697 building permits in 2008 and was ranked first in the list of healthiest housing markets for 2009.

Voters rejected efforts to have separate residential and commercial land-use districts in 1948, 1962, and 1993. Consequently, rather than a single central business district as the center of the city's employment, multiple districts have grown throughout the city in addition to downtown which include Uptown, Texas Medical Center, Midtown, Greenway Plaza, Memorial City, Energy Corridor, Westchase, and Greenspoint.

Government and politics

thumb|right|Houston City Hall
The city of Houston has a strong mayoral form of municipal government. Houston is a home rule city and all municipal elections in the state of Texas are nonpartisan. The city's elected officials are the mayor, city controller and 16 members of the Houston City Council. The current mayor of Houston is Sylvester Turner, a Democrat elected on a nonpartisan ballot.  Houston's mayor serves as the city's chief administrator, executive officer, and official representative, and is responsible for the general management of the city and for seeing that all laws and ordinances are enforced.

The original city council line-up of 14 members (nine district-based and five at-large positions) was based on a U.S. Justice Department mandate which took effect in 1979.  At-large council members represent the entire city. Under the city charter, once the population in the city limits exceeded 2.1 million residents, two additional districts were to be added. The city of Houston's official 2010 census count was 600 shy of the required number; however, as the city was expected to grow beyond 2.1 million shortly thereafter, the two additional districts were added for, and the positions filled during, the August 2011 elections.

The city controller is elected independently of the mayor and council. The controller's duties are to certify available funds prior to committing such funds and processing disbursements. The city's fiscal year begins on July 1 and ends on June 30. Chris Brown is the city controller, serving his first term as of January 2016.

As the result of a 2015 referendum in Houston, a mayor is elected for a four-year term, and can be elected to as many as two consecutive terms.Houston voters lengthen term limits for city officials ". Retrieved on January 10, 2015.</ref> The term limits were spearheaded in 1991 by conservative political activist Clymer Wright.  During 1991–2015, the city controller and city council members were subjected to a two-year, three-term limitation - the 2015 referendum amended term limits to two four year terms. As of 2017 some councilmembers who served two terms and won a final term will have served eight years in office, whereas a freshman councilmember who won a position in 2013 can serve up to two additional terms under the previous term limit law - a select few will have at least 10 years of incumbency once their term expires.

Houston is considered to be a politically divided city whose balance of power often sways between Republicans and Democrats. Much of the city's wealthier areas vote Republican while the city's working class and minority areas vote Democratic. According to the 2005 Houston Area Survey, 68 percent of non-Hispanic whites in Harris County are declared or favor Republicans while 89 percent of non-Hispanic blacks in the area are declared or favor Democrats. About 62 percent Hispanics (of any race) in the area are declared or favor Democrats.Klineberg, Stephen. Houston Area Survey 1982–2005, Page 40. The city has often been known to be the most politically diverse city in Texas, a state known for being generally conservative. As a result, the city is often a contested area in statewide elections. In 2009, Houston became the first US city with a population over 1 million citizens to elect a gay mayor, by electing Annise Parker.
