Aurora (/əˈroÊŠrÉ™/, /əˈrɔːrÉ™/) is a home rule city located in Arapahoe, Adams, and Douglas counties, Colorado, United States.^[1] The city's population was 386,261 at the 2020 United States census with 336,035 living in Arapahoe County, 47,720 in Adams County, and 2,506 in Douglas County.^[7] Aurora is the third-most-populous city in the State of Colorado and the 51st-most-populous city in the United States. Aurora is a principal city of the Denver–Aurora–Centennial, CO Metropolitan Statistical Area and the Denver-Aurora, CO Combined Statistical Area, and a major city of the Front Range Urban Corridor.

Before European settlement, the land that now makes up Aurora was the territory of the Arapaho, Cheyenne, Núu-agha-tʉvʉ-pʉ̱ (Ute), and Očeti ŠakówiÅ‹ (Sioux) tribes.^[10] These lands were claimed by France in 1682 and subsequently became part of the 1803 Louisiana Purchase.^[11]

Aurora originated in the 1890 as the town of Fletcher, taking its name from Denver businessman Donald Fletcher who saw it as a real estate opportunity. He and his partners staked out four square miles (10 km²) east of Denver, but the town—and Colorado—struggled mightily after the Silver Crash of 1893. The Town of Fletcher was incorporated on May 5, 1903.^[4] Fletcher skipped town, leaving the community with a huge water debt. Voters decided to rename Fletcher the Town of Aurora in 1907 after one of the subdivisions composing the town. The Aurora post office opened on January 15, 1908.^[12]

By February 1928, the town of Aurora had reached a population of over 2,000 and it was reincorporated as a city on March 9.^[13][14][5] Aurora slowly began to grow in Denver's shadow becoming the fastest-growing city in the United States during the late 1970s and early 1980s. Aurora, composed of hundreds of subdivisions, thus carries the name of one of the original development plats from which it sprang.

Aurora's growing population in recent decades has led to efforts for co-equal recognition with its larger neighbor.^{[citation needed]} Former mayor Dennis Champine once expressed the somewhat whimsical notion that eventually the area would be called the "Aurora/Denver Metropolitan Area". Indeed, since the 2000 Census Aurora has surpassed Denver in land area, and much of Aurora is undeveloped, while Denver is more fully built-out. However, such efforts are somewhat hampered by the lack of a large, historically important central business district in the city. Aurora is largely suburban in character, as evidenced by the city's modest number of multi-story buildings.

A large military presence has existed in Aurora since the early 20th century. In 1918, Army General Hospital #21 (later renamed Fitzsimons Army Hospital) opened, with the U.S. government expanding and upgrading the hospital facilities in 1941 just in time to care for the wounded servicemen of World War II. Lowry Air Force Base was opened in 1938, straddling the border of Aurora and Denver. It eventually closed in 1994, and has been redeveloped into a master-planned community featuring residential, commercial, business and educational facilities. In 1942, the Army Air Corps built Buckley Field, which has been renamed Naval Air Station, Buckley Air National Guard Base, Buckley Air Force Base, and finally Buckley Space Force Base. The base, home of the Buckley Garrison and the 140th Wing Colorado Air National Guard, is Aurora's largest employer.

President Warren G. Harding visited Fitzsimons Army Hospital in 1923, and President Franklin D. Roosevelt visited in 1936.^[15] In 1943, the hospital was the birthplace of 2004 Democratic presidential candidate John Kerry. President Dwight D. Eisenhower recovered from a heart attack at Fitzsimons for seven weeks during the fall of 1955. Decommissioned in 1999, the facility is part of the Anschutz Medical Campus of the University of Colorado Denver, and the Fitzsimons Life Science District. The Anschutz Medical Campus also includes the University of Colorado Hospital, which moved to Aurora from Denver in 2007, and the Children's Hospital. The first carbon-ion radiotherapy research and treatment facility in the U.S. has been proposed at the site.^[16] These facilities will employ a workforce of 32,000 at build-out.

In 1965, mayor Norma O. Walker became the first woman to head a U.S. city with a population over 60,000.

In 1978, the cult coming-of-age film Over the Edge was filmed in Aurora; the crime drama has been named the "signature film" of Denver.^[17]

In 1979, it was announced that a science fiction theme park would be built in Aurora using the sets of a $50 million film based on the fantasy novel Lord of Light. However, due to legal problems the project was never completed. The script of the unmade film project, renamed Argo, was used as cover for the "Canadian Caper": the exfiltration of six U.S. diplomatic staff trapped by the Iranian hostage crisis.

In 1993, Cherry Creek State Park on the southwestern edge of Aurora was the location for the papal mass of the 8th World Youth Day with Pope John Paul II, attended by an estimated 500,000 people.^[18]

Aurora is split among three counties and lies distant from the respective county seats. A consolidated city and county government such as those found elsewhere in Colorado (Denver and Broomfield) was considered in the mid-1990s but failed to win approval by city voters; the issue was reconsidered in 2006.^[19]

Aurora Sports Park opened in 2003. In 2004, Aurora was honored as the Sports Illustrated magazine's 50th-anniversary "Sportstown" for Colorado because of its exemplary involvement in facilitating and enhancing sports. The city attracts more than 30 regional and national sports tournaments annually to Aurora's fields. Aurora's active populace is also reflected in the variety of professional athletes hailing from the city. Aurora's first semi-professional sports franchise, the Aurora Cavalry in the International Basketball League, began play in 2006 but folded by season's end due to budget mishaps.^{[citation needed]}

In 2008, Aurora was designated an All-America City by the National Civic League.^[20]

Aurora pioneered the use of bank filtration in the United States, becoming one of the first U.S. cities to reap the benefits of siphoning water from beneath a riverbed upon completion of the Prairie Waters Project in 2010.^[21][22]

In 2017, the Republic of El Salvador opened a consulate in Aurora, serving Colorado, Kansas, Nebraska, and Wyoming.^[23] In 2024, the Republic of Honduras opened the city's second diplomatic post.^[24]

On July 20, 2012, Aurora was the site of the deadliest shooting by a lone shooter in Colorado (and the state's overall second deadliest, after the 1999 Columbine High School massacre).^[25] The shooting occurred just after midnight, when James Holmes opened fire during the midnight premiere of The Dark Knight Rises in a Century movie theater, killing 12 people and injuring 70 others.^[26] Holmes was arrested and was eventually sentenced to 12 life sentences in prison with an additional required 3,318 years. The shooting drew an international response from world leaders. U.S. President Barack Obama visited victims, as well as local and state officials, and addressed the nation in a televised address from Aurora on July 22. Actor Christian Bale, who plays Batman in the film, also visited some victims in hospitals. The events marked a turning point in recognition and public perception of the city; rather than referring to the site as being in "Denver" or "suburban Denver", as would have been typical before the event, virtually all media accounts of the incident unequivocally named "Aurora" as its location.^[27]

On August 30, 2019, Elijah McClain died six days after an unprovoked detention by two Aurora police officers.^[28] On June 27, 2020, Aurora Police in riot gear dispersed thousands of protestors at a violin concert held in his honor.^[29] On October 12, 2023, one of the officers involved in McClain's death was found guilty on charges of assault and negligent homicide, while another officer was acquitted on all charges against him, which included assault and reckless manslaughter.^[30]

Aurora received national media attention during the run-up to the 2024 U.S. presidential election. In September 2024, statements made by mayor Mike Coffman and city council member Danielle Jurinsky, both Republicans, claimed that the Venezuelan Tren de Aragua gang had taken control of an Aurora apartment complex and was extorting residents for their rent money. Jurinsky appeared on Fox News alleging "a huge cover-up" and that this "isn't just an Aurora issue." Presidential candidate Donald Trump repeated the claims during his September 10 debate with Kamala Harris, and subsequently scheduled a campaign rally in Aurora.^{[31][32][33][34]} Mayor Coffman denied the city was overrun by Venezuelan gangs.^[35] At the October 11 rally at Aurora's Gaylord Rockies Resort & Convention Center, Trump intensified his remarks regarding undocumented immigration and proposed an "Operation Aurora" to remove undocumented immigrants connected to gangs.^[36] At a press conference held the same day at Aurora's Stanley Marketplace to denounce Trump's rally, Colorado Governor Jared Polis said, "We welcome the eyes of the nation on a true Colorado gem, the great city of Aurora."^[37][38]

Following Trump's inauguration, U.S. Immigration and Customs Enforcement conducted raids targeting suspected Tren de Aragua gang members in Aurora and Denver.^[39][40] During a speech to a joint session of Congress on March 4, 2025, Trump falsely claimed immigrants “destroyed” Aurora and that the city had “buckled under the weight of migrant occupation.”^[41][42][43] The apartment complex at the root of the controversy was eventually shut down by a court order describing it as a threat to public safety. Police placed blame for the danger on property mismanagement, rather than gang activity among tenants.^[44]

Aurora's official elevation, posted on signs at the city limits, is 5,471 feet (1,668 m). However, the city spans a difference in elevation of nearly 1,000 feet (300 m). The lowest elevation of 5,285 feet (1,611 m) is found at the point where Sand Creek crosses the city limit in the northwest corner of the city, while the highest elevation of 6,229 feet (1,899 m) is on the extreme southern border of the city in Douglas County, near the intersection of Inspiration and Gartrell roads.^[45]

According to 2023 data published by the United States census, the city has a total area of 104,696 acres (423.691 km²) including 371 acres (1.500 km²) of water.^[6] The city is about 6 percent more extensive than neighboring Denver but 80 percent of the size of Colorado Springs, ranking as the 54th-largest U.S. city in land area.

Aurora is composed of dozens of neighborhoods, districts and (current and former) military installations. Among them:^{[citation needed]}

Aurora experiences a semi-arid climate (Köppen climate classification BSk), with four distinct seasons and modest precipitation year-round. Summers range from mild to hot, with generally low humidity and frequent afternoon thunderstorms, and Aurora also averages about one dozen tornado warnings throughout tornado season, running from April to July. Although a touchdown does occur every couple of years, tornadoes are typically weak and short lived. Aurora residents typically hear the tornado sirens go off numerous times more than residents in Denver, to the West. All of Aurora is located east of I-25, where tornado alley begins. Hailstorms, at times one to two-plus feet deep happen on occasion, and typical hailstorms are very common throughout these months.^[48] July is the warmest month of the year, with an average high of 89 °F (32 °C) and an average low of 57 °F (14 °C). Winters range from mild to occasional bitter cold, with periods of sunshine alternating with periods of snow, high winds and very low temperatures. December is the coldest month of the year, with an average high of 43 °F (6 °C) and an average low of 17 °F (−8 °C). The average first snowfall in the Aurora area occurs in late October and the average final snowfall occurs in late April, although snow has fallen as early as September 4 and as late as June 5. Generally, deciduous trees in the area are bare from mid October to late April.

The city of Aurora operates under a council-manager form of government, where the city manager runs the city's day-to-day operations with general guidance from the city council. The Aurora City Council is composed of a mayor and ten council members. Six members are elected from districts, while the other four are elected at large. The mayor is elected by the entire city. Aurora's mayor role is largely ceremonial, but the mayor does have direct impact on policy issues as the head of city council.^[72] The council is nonpartisan; however, parties of members have been listed below for reference.

This full-service city is protected by the Aurora Police Department,^[74] one of only 10 law enforcement agencies in Colorado to be accredited by the Commission on Accreditation for Law Enforcement Agencies; the Aurora Fire Department,^[75] which is accredited by the Commission on Fire Accreditation International; and a Public Safety Communications dispatch call center.^[76] The Aurora Municipal Courts handles a wide variety of offense violations, and the Aurora Detention Center is a 72-hour adult holding facility.^[77]

In national elections, Aurora leans to the left and the Democratic Party, though not as much as neighboring Denver but more than other suburbs in the Denver metro area. Northern and Central Aurora, due to an extremely racially and culturally diverse voter base and high density for a suburban city, are some of the most Democratic areas in Colorado and vote similarly to Denver and Boulder; southern Aurora, similar to neighboring Centennial, used to lean Republican but has swung Democratic entering the 2020s.^[78][79]

Aurora anchors Colorado's 6th congressional district and is represented in Congress by Jason Crow (D-Centennial). State representation is listed in the tables below (areas implied to be in Arapahoe County unless noted: not all districts are fully in Aurora).

Aurora straddles I-70, I-225 and the E-470 beltway. The Regional Transportation District's light rail transit system was extended to serve the southwestern edge of Aurora on November 17, 2006. The H Line stops at Aurora's Dayton and Nine Mile Stations; a comprehensive network of feeder buses in southern Aurora serve the latter. On February 24, 2017, the line was extended as the R Line to Peoria Station in the city's northwest, where riders may transfer to the A Line providing service between Union Station in Downtown Denver and Denver Airport. Much of Aurora is more convenient to Denver International Airport than Denver itself, and the city is planning an Aerotropolis along the airport's southern flank.^[89] This proximity is a factor in the expected growth of the E-470 corridor directly south of Denver International Airport, projected to eventually accommodate 250,000 additional Aurora residents.^{[citation needed]} The easternmost portions of Aurora adjoin the Colorado Air and Space Port.

In 2017, Aurora became the first city in Colorado to host a dockless bike sharing program, but operations have been suspended since August 2022.^[90]

In 2014 the U.S.A. Powerlifting Raw Nationals and the IPF Open Powerlifting World Championships were both held in Aurora. The WC was the 35th Women's and 44th Men's Open Powerlifting Championships, and it was held on the Radisson Hotel Denver Southeast.^[91]

Broomfield is a consolidated city and county located in the U.S. state of Colorado.^[1] It has a consolidated government which operates under Article XX, Sections 10–13 of the Constitution of the State of Colorado. Broomfield's population was 74,112 at the 2020 United States census,^[6] making it the 15th most populous municipality and the 12th most populous county in Colorado. Broomfield is a part of the Denver–Aurora–Lakewood, CO Metropolitan Statistical Area and the Front Range urban corridor.

The Broomfield post office opened on September 26, 1884.^[8] Historians speculate that the town was named for the sorghum grown in the area, also known as broomcorn, which had stalks that were sold to make brooms and whisk brooms.^[9]

Several railroads figure in the development of this area. The Colorado Central Railroad built a narrow-gauge line from Golden in 1873; the Denver, Utah and Pacific Railroad arrived in 1881; and the Denver, Marshall and Boulder Railway built a line through what is now Broomfield in 1886. The Denver, Utah and Pacific was widened to standard gauge in 1889. One of the early names for the area was Zang's Spur, after the railroad spur serving Adolph Zang's grain fields.^[10]

The Denver–Boulder Turnpike was constructed through the Broomfield area to speed automobile travel between the state capital of Denver and the university city of Boulder. Construction of the toll road began in 1950 and the turnpike was opened to traffic on January 19, 1952, with the sole toll plaza at Broomfield with access to U.S. Route 287 through the town.^[11] The toll to travel from Federal Boulevard in Adams County to Broomfield was 10 cents and the toll from Broomfield to Boulder was 15 cents, or 25 cents for the whole route.^[11]

The City of Broomfield was incorporated on June 6, 1961, in the southeastern corner of Boulder County.^[1] The Denver–Boulder Turnpike was a common commuting route and Broomfield became a popular residential area. On September 14, 1967, having paid off its construction and operating expenses, the turnpike was made free and became the official route of U.S. Route 36 between Denver, Boulder, and the Rocky Mountain National Park. The turnpike became the first public toll road in the United States to become free.^[11]

In the 1990s, after three decades of aggressive annexation, the City of Broomfield had expanded into Adams, Jefferson, and Weld counties in addition to Boulder.^[12] City leaders felt increasing chagrin with the need to deal with four different county governments, four separate county sales tax bases, and four separate court districts. They began pushing to make Broomfield a consolidated city-county similar to Denver, reasoning that they could provide services more responsively if Broomfield had its own county government.

The city sought an amendment to the state constitution to create a new county. The amendment was passed in 1998, after which a three-year transition period followed.

On November 15, 2001, Broomfield County became the 64th and least extensive county of Colorado. It is the newest county in Colorado (and in the entire United States, if county equivalents are not included).^[13]

Broomfield is located midway between Denver and Boulder along U.S. Routes 36 and 287 at coordinates

39°55′14″N 105°05′12″W / 39.9205°N 105.0867°W / 39.9205; -105.0867 (Broomfield, Colorado) at an elevation of 5,348 feet (1,630 m).^[3]

At the 2020 United States census, Broomfield had a total area of 21,471 acres (86.890 km²), including 371 acres (1.503 km²) of water.^[5] It is the smallest county by area in Colorado, and the 5th smallest in the United States.

Rocky Mountain Metropolitan Airport is located in Broomfield.
