Boise

The Boise metropolitan area, located in the Treasure Valley, includes five counties of Idaho with an estimated population of 846,000, the most populous metropolitan area in Idaho and 95th-most populous in the United States. Located on the Boise River in southwestern Idaho, it is 41 mi east of the Oregon border and 110 mi north of the Nevada border. Downtown Boise's elevation is 2704 ft above sea level. Home to major employers in the technology, manufacturing, and service sectors, including companies such as Micron Technology and Hewlett-Packard. The city is home to the Boise Art Museum, Idaho State Capitol, the annual Treefort Music Fest, and the Basque Block.

• Illustration — Floating the Boise River The origin of the name is uncertain. One account credits Capt. B. L. E. Bonneville of the U.S. Army as its source. After trekking for weeks through dry and rough terrain, his exploration party reached an overlook with a view of the Boise River Valley. The place where they stood is called Bonneville Point, located on the Oregon Trail east of the city. According to the story, a French-speaking guide, overwhelmed by the sight of the verdant river, yelled "Les bois! Les bois!" ("The woods! The woods!")—and the name stuck. The name may also derive from earlier mountain men who named the river that flows through the city. In the 1820s, French Canadian fur trappers associated with the British-owned Hudson's Bay Company set trap lines in the vicinity. Set in a high-desert area, the tree-lined valley of the Boise River became a distinct landmark, an oasis dominated by cottonwood trees. This led the French trappers to call the area "la rivière boisée" ("the wooded river").

Most local and longtime residents use the pronunciation (BOY-see), as given on the city's website. The pronunciation is sometimes used as a shibboleth, as those from elsewhere tend to pronounce the city's name as (BOY-zee). In French, the name of the city is pronounced /ˈbwaz/ (Bwaz).

The Boise Valley is the traditional homeland of several indigenous groups, including the Northern Shoshone and Bannock tribes. The valley had been a gathering place for trade and winter settlement. The Bannock tribe in the valley belonged to the "tuuˀagaidɨkaˀa" (black trout eaters). The Northern Shoshone belonged to the "Yahandeka" (groundhog eaters) grouping and had their main hunting lands along the lower Boise River and Payette River. In 1811, Wilson Hunt, employed as an agent in the fur trade under John Jacob Astor, organized and led the greater part of a group of about 60 men on an overland expedition to establish a fur trading outpost at the mouth of the Columbia River. This expedition passed through the Boise valley, and was the first ever time a white American has entered the region. The War of 1812 delayed use of the trade route, and the Boise Valley initially drew little attention while the rest of the Oregon Country came to be dominated by the British Hudson's Bay Company (HBC). The company established a fort in the region, the Old Fort Boise, 40 mi west, near Parma, down the Boise River near its confluence with the Snake River at the Oregon border. The HBC was present at the fort until 1844, and afterward handed it over to the United States Army.

Starting in the early 1840s, developments further west, in modern Oregon, meant significant changes to the region of Boise. At this time, HBC and the British started moving their operations further North into British Columbia, while there was a slow and steady rise in the number of settlers in Oregon Country, who demanded annexation. These developments eventually culminated in the Oregon Treaty, in which the British gave the region up to the US, thus ending the era of "Joint occupation". This meant that Boise Valley and much of Snake Country was claimed as Oregon Territory. With the discovery of gold in California in 1848 and the passage of Donation Land Claim Act, the settler incursions increased exponentially. The increased settler incursions through Shoshone and Bannock territories, and their increased exploitation of the valley's game and resources on their trip, resulted in an increasing sense of frustration among the Indigenous bands along the entire Oregon Trail. Thus, starting in the early 1850s, to deter settler caravans from using the route and trespassing on their lands, Native peoples along the entire length of the trail, from modern Eastern Idaho to modern Central Oregon started staging low-intensity attacks against passing caravans. One such attack, referred to as the "Ward Massacre", was in Boise Valley, about 20 miles west of modern Boise. On August 20, 1854, Alexander Ward's five-wagon caravan of 20 emigrants was passing through, when a group of Shoshone and Bannock warriors ambushed the caravan. The goal of the ambush was initially to take away the horses of the caravan. However, the shooting of one of the Shoshone warriors with a revolver, resulted in the killing of everyone except for two of Alexander Ward's children by the Shoshone warriors. In response, the United States Army launched the Winnas Expedition, which involved raids on Native encampments for a period of several months during the summer of 1855. In the period between 1846 and 1856, 700 white settlers were killed along the entire length of the Oregon Trail due to attacks and raids by Native warriors on their caravans while intruding native land. American military intrusion and retaliation only further angered the native tribes and escalated the conflict, which forced the United States Army to abandon Old Fort Boise. Intensified attacks against passing caravans made travel impossible for settlers except with US Army escort, which started in 1858.

The decline of the California gold rush prompted white settlers to search for gold elsewhere, including much of Idaho. The 1860 discovery of gold in Nez Perce territory near Pierce, Idaho and the resultant arrival of settlers raised tensions significantly. In September of that year, the Utter Party Massacre happened about 100 miles Southeast of Boise, where 29 out of a group of 44 settlers were either killed or captured in an intense and organized ambush. The discovery of gold around the Boise Valley in 1863, together with ongoing fighting, prompted the US Military to establish a new Fort Boise, where Boise is located today. The new location was selected because it was near the intersection of the Oregon Trail with a major road connecting the Boise Basin (Idaho City) and the Owyhee (Silver City) mining areas, both of which were booming. That year, the United States established Idaho Territory, whose boundaries included this region. After a year, with the creation of Montana Territory, Boise was made the territorial capital of a much reduced Idaho in a controversial decision that overturned a district court ruling by a one-vote majority in the territorial supreme court along geographic lines in 1866. There was no treaty and no agreement with any of the native tribes up to this point, and the violent resistance against incursion and settlement onto their territory along the Oregon Trail and at the newly found gold mines continued unabated. In order to resolve the matter of ownership and sovereignty over land, Caleb Lyon, the second governor of Idaho, negotiated with the Boise Valley Shoshone Tribe, and concluded the "Treaty of Fort Boise" on October 10, 1864. This treaty stipulated that the tribe will give up lands to 30 miles on each side of Boise River, land upon which Boise is located, while allowing an equal right to fishing in the river to both the Shoshone and the settlers. The treaty has not been ratified by the U.S. Senate to this date, and the tribe hasn't ever received any treaty payments. Backlash from the perceived friendliness of Caleb Lyon in his dealings with the tribes led to an escalation of pressure and agitation among the White Settlers in Boise and the print media in the city, in demanding either genocide or removal of the tribes. Settler violence against Boise Valley native tribes increased considerably, with some going as far as introducing bounties to murder any native. Idaho Statesman, the daily newspaper of Boise, which started publishing in 1864, reflected many such incitements and demands: David B. Madsen's quotation of the opinion column in Idaho Statesman on July 29, 1867 A "Letter to the editor" that was printed in the Idaho Statesman newspaper on October 6, 1867 At the same time, native warriors around the valley, under the leadership of Howluck, also known as "Bigfoot" among white settlers, among others, waged an escalating and intensified guerrilla campaign of harassment of passerby caravans along the Oregon Trail. The United States Army also escalated and intensified "punitive expeditions" against formations of warriors and against civilian communities as well. This marked the start of the "unofficial" Snake War in 1866. This war lasted until 1868 and is statistically the deadliest of the Indian Wars in the West in terms of casualties. In the end, 1,762 men were counted as casualties of this war from both sides. In 1868, Fort Hall Indian Reservation was established in Southeastern Idaho, about 220 miles upstream, according to the terms of Fort Bridger Treaty. The Boise Valley Shoshone and Bannock Tribes were not party to this treaty. Nevertheless, in April 1869, the United States Military embarked on a campaign of "Removal, rounding up of natives in the region including in and around Boise, and expelling them with cavalry escort to Fort Hall Indian Reservation. This period is known among the Shoshone and Bannock people as Idaho's Trail of Tears. Some of the natives managed to escape, and they ran to either Duck Valley or Fort McDermitt in Nevada.

• Illustration — Main Street in 1911 Boise's early growth was significantly driven by its role in supplying the nearby gold towns that sprung up in the 1860s northeast and then southwest of the town. Miners sometimes wintered in Boise, and a number of early prominent businessmen were miners who settled in town in the years after the gold rush waned. By 1864 substantial agricultural production was underway on easily irrigated lands near the river and three canal companies had been incorporated. Early transportation improvements were largely a result of toll road franchises awarded by the territorial legislature starting in the 1860s. These first ran from Fort Boise to the mining centers in the Boise Basin and east to Rocky Bar and to Rattlesnake Station where they connected to the Oregon Trail. Territorial census records from a special 1864 enumeration list the population of Boise as 1,658, and an act of December 12, 1864, was the first attempt by the Idaho Territorial Legislature to incorporate the city. This was rejected by voters the following March. Two more unsuccessful attempts were made to organize a city administration by election before the 1866 version of the city charter was approved by voters on January 6, 1868. The growing number of homes and businesses, for which owners wanted proper legal title, may have contributed to the eventual success of incorporation. All of these rejected efforts to incorporate the city came after Boise had been controversially made the state capital in 1864 over strong opposition from northern Idaho interests. This decision reflected the rapid shift of population growth from north to south after the discovery of gold in southern Idaho. By 1868 Boise had over 400 permanent buildings with a wide range of commercial services. 1868 also marked the formal beginning of a long advocacy for railroad connections to other Idaho communities and, just as importantly, to other growing cities in the west such as Portland, Oregon. Competing railroad and western state government interests frustrated these efforts for many years. Designed by Alfred B. Mullett, the U.S. Assay Office at 210 Main Street was built in 1871 and today is a National Historic Landmark. It first began accepting gold and silver for purchase on March 2, 1872, largely eliminating the need to transport ore to the mint in San Francisco. A territorial penitentiary, now known as the Old Idaho State Penitentiary, opened the same month several miles east of town. Mining continued to be important to Boise's economic growth, and periodic booms contributed to population growth as well, though production of gold and silver probably peaked in the 1860s. 1882's gold and silver production of $3,500,000 declined to $1,488,315 (including lead) by 1899. Boise began to earn its City of Trees nickname in this period with a popular focus on a range of tree planting projects. Thomas J. Davis planted several thousand fruit trees in 1864, and several other early businessmen either founded nurseries or orchards of their own. In the 1870s, tree planting began in earnest in downtown Boise, led by prominent hotels as well as businessmen and residents. In 1907 Davis donated 43 acres of his orchard property to the city for use as a park in the name of his wife Julia. Commercial agriculture continued to expand, but was slowed by the lack of reliable rail links to regional and national markets and by a lack of large scale irrigation projects, which themselves were often tied to hoped-for railroad projects for financing. A.D. Foote, a successful mining engineer, drew up plans to irrigate up to 500,000 acres immediately south of Boise in 1882, but progress was halting, and smaller farms were the norm until after the turn of the century, with most located near the river bottom where soil was productive and irrigation more easily achieved. Fruit orchards proliferated and sugar beets, still an important agricultural industry in Idaho, began to be widely cultivated in the 1890s. Cattle and sheep farming became increasingly important as the century closed. With the exception of dairy, most livestock products were exported from Idaho, unlike other agricultural products which were still largely scaled to support local markets. The timber industry also increasingly thrived in the Boise market in the 1880s and 1890s. Large quantities of timber were exported from elsewhere in Idaho, but a growing Boise supported the expansion of Alexander Rossi's sawmill, first established in 1865. Prominent early Boisean William Ridenbaugh had inherited control of the canal now bearing his name from his uncle William Morris in 1878 and later partnered with Rossi to expand the sawmill capacity under the name Rossi and Ridenbaugh Lumber Company. Their materials supported bridge building and the rapid expansion of Boise in the 1890s. As with many early infrastructure ventures, electrification succeeded only after at least one false start. July 4, 1887, marked the start of electrical transmission from a plant located on the Bench. William Ridenbaugh provided expertise and manpower for the water supply, and several months were spent rigging poles and lines from the Bench to the service area across the river. Additional electrical supplies allowed the building of an electric streetcar line in 1891. This ran without interruption until buses replaced the lines in 1927, tracking—and sometimes driving—the development of Boise and nearby communities. This system expanded over several decades, reaching into the North End, South Boise, and across the river on Front St. A loop line, completed in 1912, ran as far as Caldwell and Nampa, providing transport throughout the valley. Three early trolley companies merged in 1912 to form the Idaho Traction Company with a depot at 7th and Bannock Streets downtown. Additional services and urban amenities arrived in the 1890s as Boise grew. Exploratory drilling for hot water was successful in 1890, and by the end of the decade many homes along Warm Springs Avenue were being heated by this source. A natatorium was built in 1892 close to the source of the hot water near the Idaho State Penitentiary. Churches serving several denominations, a Jewish synagogue, a major hardware store and department store, a Masonic hall, the Columbia Theater, Saint Alphonsus' Hospital, a number of parochial and secular schools, a City Hall, and a new Union Pacific passenger station, constructed when service was finally extended to downtown, were all built during the 1890s. Falk's Department Store sponsored a semi-professional baseball team representing Boise from at least 1892, and the city supported other organized sports as they became popular. The 12th Census of the United States lists the population of Boise in 1900 as 5,957, up from 2,311 in 1890, when Idaho was admitted as the 43rd state.

• Illustration — View of Boise, 1932 In 1925, with the construction of Chicago-Portland railway line, Boise Union Pacific Depot was established in the city. This train station served passengers until 1997. A "homosexual panic" erupted in the city in 1955 during the lavender scare. Police interrogated hundreds of Boise citizens, arresting sixteen men whom police believed were part of a "homosexual ring." Arrests included prominent citizens, including a bank vice president. Their trials, which received sensational coverage in the local press, resulted in lengthy prison sentences; one man was sentenced to life in prison. In 2019, the city council approved the renaming of a park and natural preserve to names in the Shoshoni language to recognize their significance to local indigenous peoples. Boise and the surrounding suburbs of the Treasure Valley have a system of irrigation canals and ditches. In the early 2020s, rats were observed in the Boise area using the canals and causing pest control issues across Ada County.

• Illustration — Satellite photo of Boise and surrounding area in 2021, taken from Copernicus Sentinel-2 • Illustration — Ann Morrison Park in spring Boise is in southwestern Idaho, about 41 mi east of the Oregon border and 110 mi north of the Nevada border. The downtown area's elevation is 2704 ft above sea level. Most of the metropolitan area lies on a broad, flat plain, descending to the west. Mountains rise to the northeast, stretching from the far southeastern tip of the Boise city limits to nearby Eagle. These mountains are known to locals as the Boise foothills and are sometimes described as the foothills of the Rocky Mountains. About 34 mi southwest of Boise, and about 26 mi southwest of Nampa, the Owyhee Mountains lie entirely in neighboring Owyhee County. According to the United States Census Bureau, the city has an area of 80.05 sqmi, of which 79.36 sqmi is land and 0.69 sqmi is water. The city is drained by the Boise River and is considered part of the Treasure Valley.

Boise occupies an area of 64 sqmi, according to the United States Census Bureau. Neighborhoods of Boise include the Bench, the North End, West Boise and Downtown. In January 2014, the Boise Police Department partnered with the neighborhood blogging site Nextdoor, the first city in the Northwest and the 137th city in the U.S. to do so. Since the app, which enables the city's police, fire, and parks departments to post to self-selected, highly localized areas, first became available in October 2011, 101 neighborhoods and sections of neighborhoods have joined.

Downtown Boise is Boise's cultural center and home to many small businesses as well as a growing number of high-rises. While downtown Boise lacks a major retail/dining focus like Seattle and Portland, the area has a variety of shops and growing option for dining choices. Centrally, 8th Street contains a pedestrian zone with sidewalk cafes and restaurants. The neighborhood has many local restaurants, bars, and boutiques and supports a vibrant nightlife. The area contains the Basque Block, which gives visitors a chance to learn about and enjoy Boise's Basque heritage. Downtown Boise's main attractions include the Idaho State Capitol, the classic Egyptian Theatre on the corner of Capitol Boulevard and Main Street, the Boise Art Museum on Capitol in front of Julia Davis Park, and Zoo Boise on the grounds of Julia Davis Park. Boise's economy was threatened in the late 1990s by commercial development at locations away from the downtown center, such as Boise Towne Square Mall and at shopping centers near new housing developments. Cultural events in Downtown Boise include Alive after Five and First Thursday.

To the south of downtown Boise is Boise State University and its surrounding environs. The area is dominated by residential neighborhoods and businesses catering to the student population. The unique blue playing field at the 37,000-seat Albertsons Stadium on the BSU campus, home to the Boise State Broncos football team, is a major city landmark. Other cultural and sports centers in the area include the Velma V. Morrison Center for the Performing Arts and ExtraMile Arena. Broadway Avenue to the east and south of the BSU campus features many college-themed bars and restaurants.

• Illustration — Hyde Park • Illustration — View of north Boise from Camel's Back Park The North End, generally defined as the part of Boise north of State Street, contains many of the city's older homes. It is known for its tree-lined drives such as Harrison Boulevard, and for its quiet neighborhoods near the downtown area. Downtown Boise is visible from Camel's Back Park. On 13th Street, Hyde Park is home to restaurants and other businesses. The North End also hosts events such as the annual Hyde Park Street Fair. In 2008, the American Planning Association designated Boise's North End one of 10 Great Neighborhoods.

The Boise Highlands is just north of the North End; its location is generally defined as north of Hill Road and east of Bogus Basin Road. Annexed by the city in late 1965, the neighborhood is mostly filled with homes constructed in the 1970s, as well as the golf course of Crane Creek Country Club.

Southwest Boise contains sparsely populated neighborhoods built from the 1960s to the early 1980s. Many include acre-sized plots and the occasional farmhouse and pasture. In the 1980s, growth in the area was stunted to prevent urban sprawl. Since this has been lifted, there has been widespread growth of new homes and neighborhoods. The area lies near Interstate 84, and features, the Boise Airport, theaters, shopping, golf and the Boise Bench area.

Northwest Boise lies against the Boise Foothills to the north, State Street to the south, the city of Eagle to the west, and downtown Boise to the east. It contains a mix of old and new neighborhoods, including Lakeharbor, which features the private Silver Lake, a reclaimed quarry. Northwest Boise has some pockets of older homes with a similar aesthetic to the North End. Downtown is minutes away, as is Veteran's Memorial Park and easy access to the Boise Greenbelt. Across the river sits the Boise Bench and to the west are the bedroom communities of Eagle, Star, and Middleton.

Warm Springs is centered on the tree-lined Warm Springs Avenue and contains some of Boise's largest and most expensive homes (many of which were erected by wealthy miners and businessmen around the turn of the 20th century; Victorian styles feature prominently). The area gets its name from the natural hot springs that flow from Boise's fault line and warm many of the area's homes. The Natotorium public swim center is here.

The far-east end of Warm Springs was once known as Barber Town, featuring a hotel with hot springs nestled into the foothills. It now has some new residential developments, with easy access to Highway 21, which leads to the south-central Idaho mountains, the Boise River, the Boise Foothills, Idaho Department of Parks and Recreation, and the Idaho Shakespeare Festival.

• Illustration — The newest Boise Public Library branch at Bown Crossing Southeast Boise ranges from Boise State University to Micron Technology between Federal Way and the Boise River. Its oldest neighborhood, Original South Boise, was platted in 1890, and accordingly has variegated housing (assiduously maintained by zoning); it consists of 33 blocks bordered by W Beacon Street, S Boise Avenue, and S Broadway Avenue, and hence is a triangular neighborhood immediately adjoining BSU. The rest of Southeast Boise was developed over the decades, largely by a variety of suburban-style homes. Columbia Village subdivision and the older Oregon Trail Heights were the first major planned communities in Southeast Boise with an elementary and middle school all within walking distance from all homes. The subdivision is at the intersections of Interstate 84, Idaho 21, and Federal Way (former U.S. Highway), which are all major arteries to get anywhere in Boise. The subdivision, a baseball complex, and swimming pools were developed around the Simplot Sports complex. The fields are built over an old landfill and dump, and the fields and gravel parking lot allow radon gases to escape through the ground. The most recent planned community is the 35 acre Bown Crossing, which has easy access to the Boise Greenbelt. On August 25, 2008, at about 7:00 pm, a fire started near Amity and Holcomb during a major windstorm. It destroyed ten houses and damaged nine. One person died in the fire.

The Bench, generally bounded by Federal Way to the east, Cole Road to the west and Garden City to the north, sits on an elevation approximately 60 ft higher than downtown Boise to its northeast. Orchard Street is a major north–south thoroughfare in the neighborhood. The Bench is so named because of this sudden rise, giving the appearance of a step, or bench. The Bench (or Benches, there are three actual benches in the Boise Valley) was created as an ancient shoreline to the old river channel. The Bench is home to the Boise Union Pacific Depot. Like the North End, the Bench has older residential areas such as the Central Rim, Morris Hill, and Depot Bench neighborhoods. Due south of the Bench is the Boise Airport.

West Boise is home to Boise Towne Square Mall, the largest in the state, as well as many restaurants, strip malls, and residential developments ranging from new subdivisions to apartment complexes. The Ada County jail and Hewlett-Packard's printing division are also here. It is relatively the flattest section of Boise, with sweeping views of the Boise Front. West Boise also borders the city of Meridian.

Boise, Idaho Boise has a cool semi-arid climate (Köppen climate classification BSk, Trewartha climate classification BSak), with four distinct seasons. Boise has similar temperatures and precipitation patterns as that of a Mediterranean climate (Köppen: Csa). Boise experiences hot and dry summers with highs reaching 100 °F nine days in a typical year and 90 °F on 55 days. Yet because of the aridity, average diurnal temperature variation exceeds 30 F-change in the height of summer. Winters are moderately cold, with a December average of 32.1 °F, and lows falling to 0 °F or below on around one night per year, with some winters having several such readings and most having none at all. Snowfall averages 18 in, but typically falls in bouts of 3 in or less. Spring and fall are mild. Extremes have ranged from -28 °F on January 16, 1888, to 111 °F on July 12, 1898, and July 19, 1960; temperatures have reached -25 °F and 110 °F as recently as December 22, 1990, and August 10, 2018, respectively. Precipitation is usually infrequent and light, especially so during the summer months. It averages approximately 12 in annually. Tornadoes are rare in Ada County and the Boise area. Since 1950, only twelve tornadoes have been documented within the county, and four of those were during the same storm on August 3, 2000, which is also the most recent date a tornado was documented in the area. None of the tornadoes have been ranked higher than an F1 on the Fujita scale, and no injuries or fatalities were ever documented.
