Rapid City, South Dakota

The public discovery of gold in 1874 by the Black Hills Expedition, led by George Armstrong Custer, brought a mass influx of European-American miners and settlers into this region of the Dakota Territory. A group of unsuccessful miners founded Rapid City in 1876, trying to create other chances; they promoted their new city as the "Gateway to the Black Hills"; it was originally known as Hay Camp. The "Gateway" nickname is shared by neighboring Box Elder. In February 1876, John Richard Brennan and Samuel Scott, with a small group of men, laid out Rapid City. It was eventually named for the spring-fed Rapid Creek that flows through it.

The land speculators measured off a square mile and designated the six blocks in the center as a business section. Committees were appointed to recruit prospective merchants and their families to locate in the settlement. Such merchants soon began selling supplies to miners and pioneers. The city's location on the edge of the Plains and Hills and its large river valley made it a natural hub for the railroads that were constructed in the late 1880s from both the south and east. By 1900, Rapid City had survived a boom and bust and was developing as an important regional trade center for the Upper Midwest.

The Black Hills had become popular in the late 1890s, but Rapid City became a more important destination in the 20th century. Local entrepreneurs promoted the sights, the availability of the automobile for individual transportation, and construction of improved roadways after World War I led to many more tourists to this area, including President Calvin Coolidge and the First Lady in summer 1927. Coolidge announced that he would not seek reelection in 1928 from his summer office in Rapid City. Gutzon Borglum, already a noted sculptor, began work on Mount Rushmore in 1927, and his son, Lincoln Borglum, continued the work after Gutzon's death in 1941. The work was halted due to the US need to invest in buildup for its entry into World War II; the sculpture was declared complete in 1941. Although tourism had sustained the city throughout the Great Depression of the 1930s, gasoline rationing during World War II decimated such travel. But investments in the defense industry and other war-related growth stimulated the placement of new military installations in the area, bringing more businesses and residents.

In 1930, the Rapid City Chamber of Commerce sent a letter inviting Al Capone to live in the Black Hills.[10] South Dakota's governor did not support the idea, and Capone declined.[10]

In the 1940s Rapid City benefited greatly from the opening of Rapid City Army Air Base, later Ellsworth Air Force Base, an Army Air Corps training base. The local population nearly doubled between 1940 and 1948, from almost 14,000 to nearly 27,000. Military families and civilian personnel soon took every available living space in town, and mobile home parks proliferated. Rapid City businesses profited from the military payroll.

During the Cold War, the government constructed missile installations in the area: a series of Nike Air Defense sites were constructed around Ellsworth in the 1950s. In the early 1960s three Titan missile launch sites were constructed; these contained a total of nine Titan I missiles in Rapid City's general vicinity. Beginning in November 1963, the land for 100 miles east, northeast and northwest of the city was dotted with construction of 150 Minuteman missile silos and 15 launch command centers. They were all deactivated in the early 1990s.[11]

In 1949, city officials envisioned the city as a retail and wholesale trade center for the region. They developed a plan for growth that focused on a civic center, more downtown parking, new schools, and paved streets. A construction boom continued into the 1950s. Growth slowed in the 1960s.

After the Black Hills Flood of 1972, the worst natural disaster in South Dakota history, a building boom took place over the next decade to replace damaged structures. On June 9, 1972, heavy rains caused massive flash flooding along Rapid Creek through the city, killing 238 people and destroying more than $100 million in property.

In response to this devastation, Rapid City received an outpouring of private donations and millions of dollars in federal aid. It was able to complete a major part of its 1949 plan: clearing the area along the Rapid Creek and making the floodplain a public park. In other areas, new homes and businesses were constructed to replace those that had been destroyed. Rushmore Plaza Civic Center and a new Central High School were built in part of the area that was cleared. The high school opened in 1978, with the graduating class that year attending classes in both the original school (housed in what is now Rapid City High School and community theater) and the new one.

The rebuilding generated construction and related jobs that partly insulated Rapid City from the drop in automotive tourism caused by the 1974 Oil Embargo, but tourism was depressed for most of a decade. In 1978, Rushmore Mall was built on the city's north edge, enhancing the city's status as a local retail center.

In 1980, the Supreme Court of the United States ruled in United States v. Sioux Nation of Indians that the federal government had illegally stolen the Black Hills from the Sioux people when it unilaterally broke a treaty guaranteeing the Black Hills to them. As a result, the federal government offered a financial settlement, but the Lakota Sioux declined on the principle that the theft of their land should not be validated. They still demand the return of the land. The settlement funds accrue interest.[12] This land includes Rapid City, by far the largest modern settlement in the Black Hills. As of 2019, the dispute has not been settled.

In the 1980s, tourism increased again as the city hosted the annual Sturgis Motorcycle Rally; another decline occurred in the late 1990s. Fears that Ellsworth AFB would be closed under the BRAC review and base closure process in the 1990s and 2000s led to attempts to expand other sectors of the economy. Growth continued and the city expanded significantly during this period.

Today, Rapid City is South Dakota's primary city for tourism and recreation. With the federal government's approval of a Deep Underground Science and Engineering Laboratory at the Homestake Mine site in nearby Lead, Rapid City is primed for advancements in technology, medicine, and scientific research.

1972 Rapid Creek flood

Cars thrown together by the 1972 flood

On June 9–10, 1972, extremely heavy rains over the eastern Black Hills of South Dakota produced record floods on Rapid Creek and other streams in the area. Nearly 15 inches (380 mm) of rain fell in about six hours near Nemo, and more than 10 inches (250 mm) of rain fell over an area of 60 square miles (160 km²). According to the Red Cross, the resulting peak floods (which occurred after dark) left 238 people dead and 3,057 people injured.[13] Total property destruction was estimated in excess of $160 million (about $964 million in 2018 dollars), which included 1,335 homes and 5,000 automobiles that were destroyed.

Runoff from this storm produced record floods (highest peak flows recorded) along Battle, Spring, Rapid, and Box Elder creeks. Smaller floods also occurred along Elk and Bear Butte creeks. Canyon Lake Dam, on the west side of Rapid City, broke the night of the flood, unleashing a wall of water down the creek. The 1972 flooding has an estimated recurrence interval of 500 years,[14] which means that a flood of this magnitude will occur on average once every 500 years. Every year there is a 0.2% chance (1 in 500) that a similar event will occur. To prevent similar damage, the city has prohibited residential and business construction on its flood plain. Today the flood plain is used for civic functions such as golf courses, parks, sports arenas, and arboretums, based mostly on the landscape and temporary use by people.

In 2007, the Rapid City Public Library created a 1972 Flood digital archive[15] that collects survivors' stories, photos and news accounts of the flood. The Journey Museum has an interactive display on the 1972 flood; this is an ongoing project to give future generations the best idea of how the people were affected and what changes the city made as a result of the major losses of life and property. Plans include the memorialization of all those who died from the flood by the preparation of individual biographies, so they may be remembered more fully.

Rapid City is located at 44.076188°N 103.228299°W / 44.076188; -103.228299. The downtown elevation of Rapid City is 3,202 feet (976 m). Rapid City is located in the shadow of Black Elk Peak, which at 7,242 feet (2,207 m), is the highest point east of the Rocky Mountains.

According to the U.S. Census Bureau, the city has a total area of 55.49 square miles (143.71 km²), of which 55.41 square miles (143.5 km²) is land and 0.08 square mile (0.2 km²) is water.[16]

Rapid City is located on the eastern edge of the Black Hills, and has developed on each side of the Dakota Hogback. Rapid City's "Westside" is located in the Red Valley between the foothills of the Black Hills proper and the Dakota Hogback, so named for the red Spearfish formation soils and the way the valley completely encircles the Black Hills. Rapid City has expanded into the foothills, with developments having been built on both ridges and in valleys developed, especially in the last 20 years. This arid edge area has a higher risk of wildfire, as shown by the Westberry Trails fire in 1988.

Skyline Drive follows the summits of the Dakota Hogback south from near Rapid Gap (where Rapid Creek cuts through the Hogback) to a large high plateau that forms the current south edge of Rapid City. The Central and Eastern portions of Rapid City lie in the wide valley of Rapid Creek outside the Hogback. It includes a number of mesas rising a hundred feet or more above the floodplain.

Climate

Rapid City features a temperate semi-arid climate (Köppen: BSk) bordering on a hot-summer humid continental climate (Köppen: Dwa), and is part of USDA Hardiness zone 5b.[17] Its location makes its climate unlike both the higher elevations of the Black Hills to the west and the Great Plains to the east. It is characterized by long arid summers and long dry winters, with short but distinct spring and autumn seasons. Precipitation averages 17.44 inches or 443.0 millimetres annually, but has historically ranged from 9.12 inches or 231.6 millimetres in 1974 to 27.70 inches or 703.6 millimetres in 1946.[18][19]

Winters are cold and dry, with January being the coldest month with a daily average temperature of 24.3 °F or −4.3 °C.[18][19] Chinook winds can warm temperatures above 50 °F or 10 °C, doing so on average about 20 times from December to February.[18][19] Temperature inversions, however, occasionally produce warmer temperatures in the Black Hills. On average, highs do not climb above freezing on 43 days, while the low temperature reaches 0 °F or −17.8 °C on an average of 18 nights.[18][19] Snowfall is frequent but usually not heavy; March and April are typically the snowiest months. The seasonal total averages 48.5 inches or 1.23 metres, although historically ranging from 16.9 inches or 0.43 metres during 1980–81 to 80.9 inches or 2.05 metres during 1985–86.[18][19] Extensive snow cover does not remain for long, with only nine days seasonally with 5 inches or 0.13 metres or more on the ground.[18][19] Measurable snow has occurred in every month except July.[18]

Compared to locations in the east, the area warms rather gradually early in the year, with the last measurable snow typically occurring in late April and precipitation totals beginning to increase; May snow occurs several times per decade. Toward the middle of the year, storms typically develop over the Black Hills during the afternoon and move onto the plains in the evening. Only in April through June have calendar-day precipitation amounts exceeding 3 inches or 76.2 millimetres been observed. June 15, 1963, with 3.78 inches or 96.0 millimetres, holds the single-day rainfall record;[18] the record-wettest month is May 1996 with 8.18 inches or 207.8 millimetres.[18] Rapid City has an average of twenty clear to partly cloudy days[20] and 67% of its possible sunshine in June.[21] This is the traditional "flood" season for Rapid and other creeks in the Eastern Hills. Temperatures warm rapidly as summer approaches.

Summer in Rapid City has relatively pleasant temperatures, and is relatively dry (following a wet spring), and relatively sunny. July is the warmest month of the year, having a daily average temperature of 72.4 °F (22.4 °C).[18][19] An average of 32 days reach 90 °F (32.2 °C)+ highs and 5 with 100 °F (37.8 °C)+ highs.[18][19] Due to the elevation and aridity, lows rarely remain at or above 70 °F (21.1 °C) and during July and August fall to or below 50 °F or 10 °C on an average 7.6 days.[18] Rapid City records an average of nine thunderstorm days in August,[20] but only 1.56 inches or 39.6 millimetres of rain in that month.

Fall is a transition season: the average first freeze occurs in Rapid City on October 4 and in the Black Hills in late August through September. The Rapid City area's first snowfall is usually in October, although higher elevations sometimes receive significant snow in September. Occasional cold fronts moving through the area bring blustery northwest winds.

Sunshine is abundant in the region in all months except December, averaging 2850 hours, 64% of the possible total, per year.[21]

Rapid City holds the record for an extreme temperature drop of 47 °F or 26.1 °C, which was achieved on January 10, 1911, from 60 °F or 16 °C to 13 °F or −11 °C.[22] Official extreme temperatures range from −31 °F or −35 °C on February 2, 1996, up to 111 °F or 44 °C on July 15, 2006; the record low daily maximum is −18 °F or −28 °C on February 2, 1989, while the record high daily minimum is 75 °F or 24 °C on July 8, 1985, and July 28, 1960.[23]

Rapid City is a major healthcare center for a five-state region, centered around Monument Health Rapid City Hospital, which operates under the not-for-profit parent company Monument Health, a member of The Mayo Clinic Care Network, Monument Health continues to operate independently and is governed by a volunteer board of directors. Monument Health Rapid City Hospital has the busiest Emergency Department in South Dakota with 57,000 visits annually, they are a certified level 2 Trauma Center. Monument Health offers care in 33 medical specialties and serves 20 communities across western South Dakota and in eastern Wyoming. With over 4,500 physicians and caregivers, Monument Health consists of 5 hospitals, 8 specialty and surgical centers and more than 40 medical clinics and health care service centers. In 2017 Monument Health Rapid City Hospital received recognition as one of "America's Best 250 Hospitals for Clinical Excellence" by Healthgrades, only 258 hospitals in the United States received the prestigious award, which equals out to be just 5% of hospitals in the entire country.

There are several Urgent Care facilities in Rapid City, mainly operated by Monument Health and private for-profit groups. Monument Health has the only nationally accredited Urgent Care centers in the entire state of South Dakota.

Other independent, for-profit medical facilities have been established in the area, centered around Black Hills Surgical Hospital, which is majority owned (54.2% ownership) by Medical Facilities Corporation, a for-profit Canadian holdings company, they trade on the Toronto Stock Exchange under the symbol DR. Black Hills Neurosurgery and spine, Black Hills Orthopedics, Ballard Gynecology, ProMotion Physical Therapy, Rapid City Medical Center, Rushmore OB/GYN, The Rehab Doctors and West River ENT are all either owner by, operated or affiliated with Black Hills Surgical Hospital and for-profit parent company MFC. Other private for-profit groups exist such as Black Hills Pediatrics, Black Hills Eye Institute, as well as local, smaller providers.

Specialized government health facilities include the Indian Health Service’s Oyate Health Center (formerly Sioux San Hospital), which provides care to the Native American community, and Veterans Affairs hospitals located nearby at Fort Meade and Hot Springs, South Dakota. The VA also has a small, outpatient clinic in Rapid City.

Emergency medical services (EMS) are provided by the Rapid City Fire Department. Emergency medical transportation by rotor and fixed wing aircraft is provided by Black Hills Life Flight, operated by Air Methods Corp. based in Denver, Colorado, and MARC (Medical Air Rescue Company), owned by Dale Aviation and based in Rapid City. Apollo Air Methods also operates Medical Helicopters in the Black Hills area.

This is also the location of a number of non-profit public health organizations that engage in survey and clinic research, epidemiology, and area-based health promotion disease prevention. The Health Education and Promotion Council and Black Hills Center for American Indian Health are two notable non-profit organizations.

Rapid City Public Library

The Rapid City Public Library is a major resource for education.[28]

Rapid City institutions of higher education include the South Dakota School of Mines and Technology, Oglala Lakota College's He Sapa College Center, Black Hills State University - Rapid City University Center (includes classes and degrees through five other South Dakota post-secondary Institutions), National American University, Western Dakota Technical Institute, Black Hills Beauty College, John Witherspoon College, and several small sectarian preacher training schools.

Black Hills State University is located in nearby Spearfish and offers several classes in Rapid City. A South Dakota State University nurse training program is based in Rapid City.

In 2013, 26.6% of Rapid City residents 25 or older had earned a bachelor's degree or higher.[29] This is on par with the average educational attainment in the United States. The highest rates of educational attainment in South Dakota can be found in metropolitan areas of Rapid City and Sioux Falls.

The local public schools fall under the Rapid City Area Schools school district. There are three high schools within the district: Rapid City Central High School; Stevens High School; and Rapid City High School, which also houses the Performing Arts Center. The middle schools include East, North, South, Southwest, and West. There are 16 elementary schools within the district. These are Black Hawk, Canyon Lake, Corral Drive, General Beadle, Grandview, Horace Mann, Kibben Kuster, Knollwood Heights, Meadowbrook, Pinedale, Rapid Valley, Robbinsdale, South Canyon, South Park, Valley View, and Woodrow Wilson.[30]

There are also various private schools in Rapid City. The city has four Christian high schools: Saint Thomas More, Rapid City Christian High School, Liberty Baptist Academy, and Open Bible Christian School. Rapid City also has various private grade schools, including St. Paul's Lutheran School of the WELS.[31]

Because of the importance of tourism in the area, and its extensive market area, Rapid City has many cultural resources usually found only in much larger urban areas. Among these are:

President John F. Kennedy and John Jr., The City of Presidents, Rapid City

Rapid City has invested in public sculptures, which are on display in many parts of the city. The most visible is "The City of Presidents", a series of life-sized bronze statues representing each former President of the United States. The statues are located on street corners in the downtown area. Five South Dakota artists created the statues: Edward E. Hlavka, Lee Leuning, John Lopez, James Michael Maher, and James Van Nuys.[41] The first 42 statues were erected via private donations over a ten-year period between 2000 and 2010. As of 2019, Barack Obama is the most recent president to have a statue erected; currently sitting presidents are ineligible.

Rapid City has three sister cities, as designated by Sister Cities International:

• Apolda, Thuringia, Germany
• Nikkō, Tochigi, Japan[42]
• Yangshuo County, Guangxi, China

Rapid City's economy is diverse, but industry is a small portion. Heavy and medium industrial activities include a Portland cement plant (constructed and owned for 84 years[43] by the State of South Dakota and sold in 2003 to Grupo Cementos de Chihuahua, or GCC, a Mexican-based conglomerate); Black Hills Ammunition, an ammunition and reloading supplies manufacturing company; several custom sawmills, a lime plant, a computer peripheral component manufacturing plant, and several farm and ranch equipment manufacturers. Of particular note, this city is the center for the manufacture of Black Hills gold jewelry, a popular product with tourists and Westerners in general. The city is the site of the only American manufacturer of stamping machines used for the labeling of plywood and chipboard products.

Most gold mining has ceased in the Black Hills and was never conducted in or near Rapid City. Regional mining operations include for sand and gravel, as well as the raw materials for lime and Portland cement (including chemical-grade limestone, taconite iron ore, and gypsum) remains an important part of the economy.

The largest sector of the Rapid City economy is government services, including local, state, and federal. Major employers include Ellsworth Air Force Base,[44] home of the 28th Bomb Wing flying the B-1B long-range bomber; the Army National Guard based at Camp Rapid and hosting annual exercises in the Black Hills, drawing troops from five to ten states; and various federal agencies, including the National Park Service, US Forest Service, and Indian Health Service.

Monument Health covers one of the largest geographic service areas in the United States. The health care sector employs more than 8,000 persons in the Rapid City area.[44]

Tourism constitutes a major portion of the Rapid City economy,[44] due to the proximity of Mount Rushmore, Sturgis, home of the Sturgis Motorcycle Rally; Deadwood, and other attractions in the Black Hills. This city provides most services for the Motorcycle Rally. Prepared to satisfy the Rally's demand for motel rooms, camp sites, and other services for tourists during the first week of August, Rapid City has the capacity to host other large events, such as conventions, and numerous associated tourists year-round. Various minor tourist attractions, including wildlife parks, specialty shops, caves, water parks, private museums, and other businesses are found in and near Rapid City.

Other economic sectors include financial service and investing companies such as Waddell and Reed, Citibank, WaMu, Merrill Lynch, and Northwestern Mutual. Rapid City is the headquarters for Assurant Insurance's pre-need division. As noted, the city has a strong medical services sector, and several institutions of higher education. Rapid City is also the major market town for much of five states, drawing commerce from more than half of South Dakota, and large portions of North Dakota, Montana, Wyoming, and the Nebraska Panhandle.

The real compound annual growth rate of the gross domestic product of the Rapid City Metropolitan Statistical Area was 2.6% for 2001–2013.[45]

• Interstate 90 is the primary east–west route for Rapid City. The city is served by a series of 7 exits. I-90 skims the northern side of the city. The South Dakota DOT has been reconstructing most of these interchanges in the last five years.
• Interstate 190 is an Interstate spur linking downtown Rapid City to Interstate 90.
• US Highway 16 is the main route to the southwest and the Black Hills from Rapid City. It links Rapid City to Custer, then west to Newcastle, Wyoming, where it connects to US Highway 85 for travel to Cheyenne and Denver. Reconstructed in the mid-1960s as a four-lane parkway connecting Rapid City to Mount Rushmore, since 2008 major segments have been rebuilt as three-lane, or "super-two" highways, to support increased tourist traffic.
• South Dakota Highway 44 is a state highway that links the interior of the Black Hills to the southwest of Rapid City, and the Pine Ridge Indian Reservation and nearby areas in the Great Plains to the southeast.
• South Dakota Highway 79 is a state highway that is multiplexed with I-90 northwest of Rapid City. SD Highway 79 extends to North Dakota. South of Rapid City to Nebraska, Highway 79 is being reconstructed as the Heartland Expressway, a high-speed, four-lane highway that will eventually connect to Interstate 80 in Nebraska and the Colorado Front Range near Denver. The Heartland Expressway may eventually be extended along US Highway 85 north to Regina, Saskatchewan, to create an additional major north–south artery through the Great Plains that would pass through Rapid City.

Rapid City is located on the boundary of the Western and Eastern power grids. It is served by the hydroelectric plants of the two Mainstem dams on the Missouri River, and the large coal fields and power plants of the Powder River Basin of Wyoming. It is located where the two national power grids connect with each other, allowing switching of electrical power from east to west and vice versa. Rapid City had its own coal-fired power plant but could not afford to meet current air pollution standards and closed it. Closed for similar reasons were coal-fired power stations near Gillette, Wyoming. The Ben French power station located within city boundaries shut down September 2012, more than two years ahead of its scheduled shutdown. Rapid City now obtains much of its power from the Missouri dams and importing it from elsewhere. Following the shut down of the plants dependent on cheap, polluting coal, electrical rates have risen. The city has had to spend more to import electricity over a longer distance.

National Guard officer candidates take part in a tactical road march through a west Rapid City neighborhood.

Rapid City obtains most of its water supply from Rapid Creek and the alluvial aquifers associated with the creek, owning significant water rights in Pactola Reservoir located some 15 miles (24 km) west of the city, but does also obtain water from some springs in the vicinity, and has the ability to draw water from deep formations that receive water from recharge in areas of the Black Hills where the formations come to the surface. The heavy dependence on shallow alluvial aquifers is of some concern to planners, as most suburbs of Rapid City use septic systems for domestic sewage treatment. However, water supplies remain relatively good for future growth.

Rapid City has a municipally owned bus service, providing multiple bus stops and a headquarters in the city. It has limited city-to-city bus service along I-90. Charter bus services operate in the area, connecting Rapid City and Deadwood with cities in Colorado, Nebraska, and Iowa.

The 2020 Census population of the Rapid City Metropolitan Statistical Area (Pennington, Meade and Custer counties) was 139,074. A significant portion of residents from cities and towns in the Black Hills and nearby plains commute to Rapid City for work.
