Construction ↔ relates to ↔ Employment Workforce

Construction is the process involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any work to expand, extend, and improve the asset, and its eventual demolition, dismantling, or decommissioning. The construction industry contributes significantly to many countries' gross domestic products (GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many countries, but it is one of the most hazardous industries.

. Etymology "Construction" stems from the Latin word constructio (which comes from com- "together" and struere "to pile up") as well as Old French construction. "To construct" is a verb: the act of building. The noun is "construction": how something is built or the nature of its structure. History The first huts and shelters were constructed by hand or with simple tools. As cities grew during the Bronze Age, a class of professional craftsmen, like bricklayers and carpenters, appeared. Occasionally, slaves were used for construction work. In the Middle Ages, the artisan craftsmen were organized into craft guilds. In the 19th century, steam-powered machinery appeared, and later, diesel- and electric-powered vehicles such as cranes, excavators and bulldozers. Fast-track construction has been increasingly popular in the 21st century.

Fast-track construction has been increasingly popular in the 21st century. Some estimates suggest that 40% of construction projects are now fast-track construction. Construction industry sectors Broadly, there are three sectors of construction: buildings, infrastructure and industrial: Building construction is usually further divided into residential and non-residential. Infrastructure, also called 'heavy civil' or 'heavy engineering', includes large public works, dams, bridges, highways, railways, water or wastewater and utility distribution. Industrial construction includes offshore construction (mainly of energy installations), mining and quarrying, refineries, chemical processing, mills and manufacturing plants. The industry can also be classified into sectors or markets. For example, Engineering News-Record (ENR), a US-based construction trade magazine, has compiled and reported data about the size of design and construction contractors. In 2014, it split the data into nine market segments: transportation, petroleum, buildings, power, industrial, water, manufacturing, sewage/waste, telecom, hazardous waste, and a tenth category for other projects. ENR used data on transportation, sewage, hazardous waste and water to rank firms as heavy contractors. The Standard Industrial Classification and the newer North American Industry Classification System classify companies that perform or engage in construction into three subsectors: building construction, heavy and civil engineering construction, and specialty trade contractors.

Apprenticeship is a system for training potential new practitioners of a trade or profession with on-the-job training and often some accompanying study. Apprenticeships may also enable practitioners to gain a license to practice in a regulated occupation. Most of their training is done while working for an experienced employer who helps the apprentices learn their trade or profession, in exchange for their continued labor for an agreed period after they have achieved measurable competencies. Apprenticeship lengths vary significantly across sectors, professions, roles and cultures. In some cases, people who successfully complete an apprenticeship can reach the "journeyman" or professional certification level of competence. In other cases, they can be offered a permanent job at the company that provided the placement.

States Department of Labor that originally had federal visitorial powers to inspect and examine workplaces. The United States Congress established the agency under the Occupational Safety and Health Act (OSH Act), which President Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance". The agency is also charged with enforcing a variety of whistleblower statutes and regulations.

History From its creation in 1934, the Bureau of Labor Standards of the Department of Labor addressed some work safety issues. The economic boom and associated labor turnover during World War II worsened work safety in nearly all areas of the United States economy, but after 1945 accidents again declined as long-term forces reasserted themselves. Additionally, new and powerful labor unions played an increasingly important role in worker safety post-World War II. In the 1960s, increasing economic expansion again led to rising injury rates, and the resulting political pressures led Congress to establish the Occupational Safety and Health Administration (OSHA) on April 28, 1971, the date that the Occupational Health and Safety Act became effective. The new agency incorporated much of what had been the original Bureau of Labor Standards. George Guenther was appointed by Labor Secretary James D. Hodgson as the agency's first director. OSHA has run a number of training, compliance assistance, and health and safety recognition programs throughout its history. The OSHA Training Institute, which trains government and private sector health and safety personnel, began in 1972. In 1978, the agency began a grant-making program, now called the Susan Harwood Training Grant Program, to train workers and employers in reducing workplace hazards.

OSH Act coverage The OSH Act covers most private-sector employers and their workers, in addition to some public-sector employers and workers in the 50 states and certain territories and jurisdictions under federal authority. Those jurisdictions include the District of Columbia, Puerto Rico, the Virgin Islands, American Samoa, Guam, Northern Mariana Islands, Wake Island, Johnston Island, and the Outer Continental Shelf Lands as defined in the Outer Continental Shelf Lands Act. Private sector employers The OSH Act covers most private sector employers in all 50 states, the District of Columbia, and other U.S. jurisdictions—either directly through federal OSHA or through an OSHA-approved state plan. State plans are OSHA-approved job safety and health programs operated by individual states instead of federal OSHA. Federal OSHA approves and monitors all state plans and provides as much as fifty percent of the funding for each program.

Micron Technology, Inc. is an American multinational semiconductor company that manufactures computer memory and computer data storage products, including dynamic random-access memory (DRAM), flash memory, High Bandwidth Memory (HBM), and solid-state drives (SSDs). Founded in 1978 in Boise, Idaho, Micron is the only major American computer memory manufacturer. It is one of the "Big Three" computer memory manufacturers, along with the South Korean companies Samsung Electronics and SK Hynix. Micron marketed its consumer products under the brand Crucial, with the sub-brand Ballistix being used to denote products targeting gaming computers, until its disestablishment on 2026. Micron and Intel together created IM Flash Technologies, which produced NAND flash memory. It owned Lexar between 2006 and 2017. Sanjay Mehrotra has served as president and CEO of Micron since 2017. On May 26, 2026, Micron became the latest U.S.

Since 2000 In 2000, Gurtej Singh Sandhu and Trung T. Doan at Micron initiated the development of atomic layer deposition high-k films for DRAM memory devices. This helped drive cost-effective implementation of semiconductor memory, starting with 90 nm node DRAM. Pitch double-patterning was also pioneered by Gurtej Singh Sandhu at Micron during the 2000s, leading to the development of 30-nm class NAND flash memory, and it has since been widely adopted by NAND flash and RAM manufacturers worldwide. In 2002, Micron spun off its personal computer business as MPC Corporation and put it up for sale. The company found the business difficult as the number 12 American computer maker with only 1.3 percent of the market. Micron and Intel created a joint venture in 2005, based in IM Flash Technologies in Lehi, Utah. The two companies formed another joint venture in 2011, IM Flash Singapore, in Singapore. In 2012 Micron became sole owner of this second joint venture. In 2006 Micron acquired Lexar, an American manufacturer of digital media products. The company changed leadership again in June 2007 with COO Mark Durcan becoming president. In 2008, Micron converted the Avezzano chip fab, formerly a Texas Instruments DRAM fab, into a production facility for CMOS image sensors sold by Aptina Imaging. In 2008, Micron spun off Aptina Imaging, which was acquired by ON Semiconductor in 2014. Micron retained a stake in the spinoff. However, the core company suffered setbacks and had to layoff 15 percent of its workforce in October 2008, during which period the company also announced the purchase of Qimonda's 35.6 percent stake in Inotera Memories for $400 million. The trend of layoffs and acquisitions continued in 2009 with the termination of an additional 2,000 employees, and the acquisition of the FLCOS microdisplay company Displaytech. Micron agreed to buy flash-chip maker Numonyx for $1.27 billion in stock in February 2010. On February 3, 2012, CEO Appleton died in a plane crash shortly after takeoff from the Boise Airport. He was the pilot and sole occupant of the Lancair IV aircraft. Mark Durcan replaced Appleton as the CEO shortly thereafter, eliminating his former title of president. In 2013, the Avezzano chip fab was sold to LFoundry. In the 2012 to 2014 period, Micron again went through an acquisition-layoff cycle, becoming the majority shareholder of Inotera Memories, purchasing Elpida Memory for $2 billion and the remaining shares in Rexchip, a PC memory chip manufacturing venture between Powerchip and Elpida Memory for $334 million, while announcing plans to lay off approximately 3,000 workers. Through the Elpida acquisition, Micron became a major supplier to Apple Inc. for the iPhone and iPad. In December 2016 Micron finished acquiring the remaining 67 percent of Inotera, making it a 100 percent subsidiary of Micron. In April 2017, Micron announced Sanjay Mehrotra as the new president and CEO to replace Mark Durcan. In June 2017 Micron announced it was discontinuing the Lexar retail removable media storage business and putting some or all of it up for sale. In August of that year the Lexar brand was acquired by Longsys, a flash memory company based in Shenzhen, China. In May 2018, Micron Technology and Intel launched QLC NAND memory to increase storage density. The company ranked 150th on the Fortune 500 list of largest United States corporations by revenue. In February 2019, the first microSD card with a storage capacity of 1 terabyte (TB) was announced by Micron. As of March 2020 3.84TB Micron 5210 Ion is the cheapest large-capacity SSD in the world. In September 2020 the company introduced the world's fastest discrete graphics memory solution. Working with computing technology leader Nvidia, Micron debuted GDDR6X in the Nvidia GeForce RTX 3090 and GeForce RTX 3080 graphics processing units (GPUs). In November 2020, the company unveiled a new 176-layer 3D NAND module. It offers improved read and write latency and is slated to be used in the production of a new generation of solid-state drives. On October 22, 2021, Micron closed the sale of IM Flash's Lehi, Utah fab to Texas Instruments for a sale price of US$900 million. In February 2022, Micron announced that it would discontinue its Ballistix gaming brand. With the passage of the CHIPS and Science Act, Micron announced its pledge to invest billions in new manufacturing within the United States. In September 2022, Micron announced it would invest $15 billion in a new facility in Boise, Idaho. In October 2022, Micron announced a $100 billion expansion in Clay, New York. Micron Technology owed Netlist, Inc. $445 million in damages for infringing Netlist's patents related to memory-module technology for high-performance computing. The jury found that Micron's semiconductor-memory products violated two of Netlist's patents willfully, potentially allowing the judge to triple the damages. Netlist had sued Micron in 2022, accusing three of its memory-module lines of patent infringement, which Micron denied, also arguing the patents' invalidity. The U.S.

n since 2017. On May 26, 2026, Micron became the latest U.S. company to reach a US$1 trillion market capitalization, amid surging demand for its HBM chips. History 1978–1999 Micron was founded in Boise, Idaho, in 1978 by Ward Parkinson, Joe Parkinson, Dennis Wilson, and Doug Pitman as a semiconductor design consulting company. Startup funding was provided by local Idaho businessmen Tom Nicholson, Allen Noble, Rudolph Nelson, and Ron Yanke. Later it received funding from Idaho billionaire J. R. Simplot, whose fortune was made in the potato business. In 1981, the company moved from consulting to manufacturing with the completion of its first wafer fabrication unit ("Fab 1"), producing 64K DRAM chips. In 1984, the company had its initial public offering. Micron sought to enter the market for RISC processors in 1991 with a product known as FRISC, targeting embedded control and signal processing applications. Running at 80 MHz and described as "a 64-bit processor with fast context-switching time and high floating-point performance", the design supported various features for timely interrupt handling and featured an arithmetic unit capable of handling both integer and floating-point calculations with a claimed throughput of 80 MFLOPS for double-precision arithmetic. Micron aimed to provide a "board-level demonstration supercomputer" in configurations with 256 MB or 1 GB of RAM. Having set up a subsidiary and with the product being designed into graphics cards and accelerators, Micron concluded in 1992 that the effort would not deliver the "best bang for the buck", reassigning engineers to other projects and discontinuing the endeavour. In 1994, founder Joe Parkinson retired as CEO and Steve Appleton took over as Chairman, President, and CEO. A 1996 3-way merger among ZEOS International, Micron Computer, and Micron Custom Manufacturing Services (MCMS) increased the size and scope of the company; this was followed rapidly with the 1997 acquisition of NetFrame Systems, in a bid to enter the mid-range server industry.

, coined the name "Treasure Valley" in 1959 to reflect the treasure chest of resources and opportunities that the region offered. The valley has a very diverse terrain, from sage flatlands, to mesas, agricultural areas, and urbanized areas. As the Boise Metropolitan Area grows, more and more undeveloped and agricultural land is being urbanized. History Settling the region The tribes that roamed the area, specifically, were the Northern Paiute and Shoshone. In 1834, Thomas McKay built the original Fort Boise, in the area near present-day Parma, which was run for a time by Francois Payette. It later was moved because of flooding troubles and was abandoned in 1854. The Oregon Trail runs through the Treasure Valley. The valley was settled for the most part by ranchers and farmers, initially to supply the gold and silver mining communities in the higher elevations nearby: Idaho City in the Boise Basin and Silver City in the Owyhees. A new Fort Boise was constructed by the U.S. Army in 1863 in present-day Boise, from which the city grew.

ern Oregon to Boise, and is the most populated area in Idaho. Historically, the valley had been known as the Lower Snake River Valley or the Boise River Valley.

The Treasure Valley is a valley in the western United States, primarily in southwestern Idaho, where the Payette, Boise, Weiser, Malheur, and Owyhee rivers drain into the Snake River. It includes all the lowland areas from Vale in rural eastern Oregon to Boise, and is the most populated area in Idaho.

pa ( ) is the most populous city in Canyon County, Idaho, United States. The population was 100,200 at the 2020 census. It is Idaho's third-most populous city. Nampa is about 20 miles (32 km) west of Boise along Interstate 84, and 6 miles (9.7 km) west of Meridian. It is the second principal city of the Boise metropolitan area. The name "Nampa" may have come from a Shoshoni word meaning 'moccasin' or 'footprint'. According to toponymist William O. Bright, the name comes from the Shoshoni word /nampai/, meaning "foot".

History Nampa had its beginnings in the early 1880s when the Oregon Short Line Railroad built a line from Granger, Wyoming, to Huntington, Oregon, that passed through Nampa. In Nampa there is a history museum that marks the railroad's significance. More railroad lines sprang up through Nampa, making it an important railroad town. Alexander and Hannah Duffes established one of the town's first homesteads, eventually forming the Nampa Land and Improvement Company with the help of their friend and co-founder, James McGee. Despite the name, many early settlers called the town "New Jerusalem" because of its citizens' strong religious focus. After only a year the town grew from 15 homes to 50. As amenities were added, Nampa continued to grow, and it was incorporated in 1891. Downtown Nampa's street grid is oriented with the railroad tracks, which run northwest–southeast; this was done intentionally by Alexander Duffes to prevent accidents like one that occurred earlier in a town he had platted near Toronto, where a woman and her two children were killed by a train when their buggy wheel got stuck as they crossed the tracks. As the Oregon Short Line railroad originally bypassed Boise, Nampa has the fanciest of many railroad depots built in the area. Nampa gained attention in 1889 due to a purported archaeological discovery known as the Nampa figurine. George Frederick Wright wrote up details that year for the Boston Society of Natural History. The first elementary school was built in the 1890s. Lakeview School was on a hill on 6th Street and 12th Avenue North, with a view of Lake Ethel. Just after the school's centennial celebration, it was condemned as a school and sold to the First Mennonite Church. In 2008 the building was refurbished, and it is now used by the Idaho Arts Charter School. Lake Ethel, an irrigation reservoir, had long been the site of community picnics, and many citizens fished, swam, boated, and even hunted on it and its surrounding property. But the hunting didn't last long, as O. F. Persons, owner of the adjoining homestead, took offense when local hunters started shooting his pet ducks. The city later auctioned off the lake. E. H. Dewey (a former Nampa mayor) was the only bidder. But occasional flooding led to a series of lawsuits from neighbors. Dewey eventually drained Lake Ethel. Not long after, the city council became interested in buying back the Fritz Miller property as well as the Dewey home. Pressure had been building for more than four years. Nampa citizens wanted another park. On August 7, 1924, the city council passed an ordinance to purchase the Miller property and name it Lakeview Park. A bandstand was completed in 1928, and the municipal swimming pool opened on August 13, 1934. It is Nampa's largest park and many community celebrations are held there. Colonel William H. Dewey, a man who made a fortune mining in Silver City, built the Dewey Palace Hotel in 1902 for $250,000. He died in his hotel in 1903, leaving his son $1 million. The hotel survived the great fire of 1909, which burned several blocks of downtown Nampa, but was razed in 1963 after redevelopment plans failed. Relics from the hotel such as the chandelier and the hotel safe can be found at the Canyon County Historical Museum, which is in the old train depot on Front Street and Nampa City Hall. After demolition the location on First Street between 11th and 12th Ave. South was sold to private enterprise, including a bank and tire store, replacing this building with modern structures. A public-use postage stamp sized park was later placed across the street from the old palace property as a collaboration between the Downtown Alliance of Nampa (the local business council) and an Eagle Scout Project for the Boy Scouts of America. The park includes a large mural/wall sculpture of running horses commissioned for the project. A Carnegie library was built downtown in 1908; it burned down after the library moved in 1966. Nampa Public Library was then on the corner of 1st Street and 11th Avenue South in the old bank building. A new library, on 12th Avenue South, opened in 2015. Deer Flat Reservoir, an offstream irrigation storage reservoir, was constructed by the United States Bureau of Reclamation between 1906 and 1911. Known locally as Lake Lowell, it is surrounded by the Deer Flat National Wildlife Refuge, established in 1909 by President Theodore Roosevelt. The refuge is administered by the U.S. Fish and Wildlife Service. Lake Lowell is filled by the concrete New York Canal; the water is diverted from the Boise River a few miles below Lucky Peak Dam. In 1910, the Idaho State School and Hospital was built northwest of Nampa for the state's developmentally challenged population. It opened in 1918. The institution was largely self-sufficient, with a large farm staffed by the residents. The higher-functioning residents also cared for residents who could not care for themselves. The land for the farm was sold and is now golf courses (Centennial and Ridgecrest), and the residents no longer give primary care to other residents. The institution is modernized and remains in operation, though a few of the oldest buildings now house juvenile offenders. Nampa held an annual harvest festival and farmers' market from about 1908, a time of celebration and community fun. From this festival emerged the Snake River Stampede Rodeo in 1937, which continues to this day. It is one of the top 12 rodeos in the pro rodeo circuits. In 1913, a local congregation of the Church of the Nazarene built a small elementary school, which became to Northwest Nazarene College in 1915 and finally Northwest Nazarene University. As of 2025, the university has approximately 1,800 undergraduate and graduate students. Karcher Mall opened in 1965, the first enclosed shopping mall in the Treasure Valley. It was "the place to gather" for several decades until the Boise Towne Square mall was built in Boise in 1988, drawing business away. Karcher Mall was renamed District 208 in 2022. The Idaho Press-Tribune is the local newspaper for the Canyon County area.

Idaho Hispanic Community Center (IH2C) In 2003, the Hispanic Cultural Center of Idaho (HCCI) opened thanks to community support. It has recently transitioned back to the City of Nampa and was renamed the Idaho Hispanic Community Center (IH2C) and is home to the Idaho Hispanic Foundation. It hosts events, classes, and festivals, including Día de los Muertos, Hispanic Heritage Month, and Día Internacional de la Mujer. It serves as a meeting place for associations and groups. Displays of cultural history are available to the public. Nampa Train Depot Museum The Nampa Train Depot Museum is a historical depot with displays and archives of the area's railroad and cultural history. The Canyon County Historical Society saved the depot from demolition in 1972. Annual Festival of the Arts Nampa's Festival of the Arts, which began in 1987, is held in Lakeview Park every year and includes local art, music, dance, and food.

city in Idaho. As of the 2020 census, Caldwell had a population of 59,996. Caldwell is considered part of the Boise metropolitan area, and is the location of the College of Idaho. The city is located approximately 24 miles (39 km) west of Boise, and approximately 17 miles (27 km) east of the Oregon border. History The present-day location of Caldwell is along a natural passageway to the Inland and Pacific Northwest. Native American tribes from the west coast, north Idaho and as far away as Colorado came to the banks of the Boise River for annual trading fairs, or rendezvous. European and some Hawaiian explorers and traders soon followed the paths left by Native Americans and hopeful emigrants later forged the Oregon Trail and followed those paths to seek a better life in the Oregon Territory. Pioneers of the Trail traveled along the Boise River to Canyon Hill and forded the river close to the Silver Bridge on Plymouth Street. During the Civil War, the discovery of gold in Idaho's mountains brought a variety of new settlers into the area. Many never made it to the mines but settled along the Boise River and run ferries, stage stations, and freighting businesses. These early entrepreneurs created small ranches and farms in the river valleys. Caldwell's inception occurred largely as a result of the construction of the Oregon Short Line Railroad, which connected Wyoming to Oregon through Idaho. Robert E. Strahorn came to the Boise River Valley in 1883 to select a route for the railroad. He rejected the grade into Boise City as too steep and chose a site 30 miles to the west. He drove a stake into an alkali flat of sagebrush and greasewood and the City of Caldwell was platted. Caldwell was named after one of Strahorn's business partners, Alexander Caldwell, a former senator from Kansas. When Caldwell was platted in August 1883, its founder, the Idaho and Oregon Land Improvement Company, started persuading settlers and businessmen to move to the area. Within four months, Caldwell had 600 residents living in 150 dwellings, 40 businesses, a school, a telephone exchange, and two newspapers. On January 15, 1890, the Board of Commissioners of Ada County issued a handwritten order incorporating the City of Caldwell. The College of Idaho was founded in Caldwell in 1891. In 1892, Canyon County was established from a portion of Ada County, and Caldwell was named the county seat. Irrigation canals and waterways were constructed throughout Canyon County, providing the foundation for an agricultural economy. The Oregon Short Line Railroad became part of the larger Union Pacific Railroad network and in 1906 the Caldwell freight and passenger depot was constructed. Caldwell experienced moderate growth as an agricultural processing, commercial retail and educational center during the 20th century. In 2009, the City of Caldwell completed a revitalization project to restore Indian Creek, which runs through downtown Caldwell, but had been used for sewage disposal by local industries and been covered over.

Meridian is a city located in Ada County, Idaho, United States. The population was 117,635 at the 2020 census, making it the second most populous city in the county and Idaho, after Boise, the state capital.

Rail transportation (1908–28) Following the raising of $4,000 to lay the Interurban rail line from Onweiler (Meridian and Ustick Roads), the tracks were completed into the village center. Turning east on Broadway and ending at East Second, the last car would spend the night in Meridian before returning to Boise early the next morning with passengers and freight. The interurban Station and Generator building (west one-third of the old library at Meridian and Idaho Streets) was built in 1912, and the line continued on to Nampa via Meridian. The tracks down Broadway were not used after 1912. The Interurban Company entered into receivership and closed in 1928 after 20 years of providing continuous transportation to neighboring towns. It was Meridian's main connection to the area outside the local community. The Union Pacific Railroad spur opened in 1900 and is currently operated by the Boise Valley Railroad. Many industrial customers continue to ship forest, agricultural, and chemical products along this corridor. Creamery (1929–70) The city's official website describes the history of the Ada County Dairymen's cooperative creamery as follows:The lowest days of the Great Depression brightened for area dairymen when the Ada County Dairymen's cooperative creamery began operation in 1929. It provided milk checks to those who were members of the cooperative, enabling them to pay their taxes and provide food for their families. Other community members hauled milk to the creamery and were employed by the creamery, whose product was Challenge Butter. The creamery ran seven days a week for 40 years. Additions and improvements were made while the plant was in full operation. Later years saw the Wyeth Laboratories affiliate with the creamery to manufacture SMA baby formula.

History Journeymen in the pipe trades in the 1880s worked in three basic crafts: plumbers, steamfitters and gasfitters. The first truly successful national body, the United Association of Journeymen Plumbers, Gas Fitters, Steam Fitters, and Steam Fitters' Helpers of the United States and Canada, was officially founded on October 11, 1889. Gradually, former members of rival unions joined the United Association. The depression of 1893–1897 slowed the development of a stronger organization. Membership in the United Association grew to 6,700 in 1893, but fell to 4,400 by 1897. Yet, by that year 151 local unions were listed on its rolls. Starting in 1898, the construction industry entered a period of expansion and prosperity that lasted until 1914. From 1898 to 1906 the United Association quadrupled its membership. During its first years, the United Association was essentially a federation of local unions, rather than a truly national union of the pipe trades. The major breakthrough toward a unified national organization came at the 1902 national convention in Omaha, when delegates approved a Nationalization Committee proposal establishing a comprehensive system of sick, death and strike benefits. As such reforms to strengthen the national organization were being made in the early part of the century, however, some locals broke ranks to form a rival union. In August 1906, members of the secessionist union realized the futility of further rivalry and agreed to affiliate with the United Association. From 1898 to 1914, the United Association went through several phases of a struggle with the International Association of Steam and Hot Water Fitters and Helpers, a prolonged and sometimes bitter dispute both over jurisdiction over a craft (steamfitting) and work assignments (plumbers vs. steamfitters). The conflict affected other building trades when walkouts by the rival steamfitting organizations, as a result of their jurisdictional dispute, led to work stoppages by other crafts. The strength of the United Association, and favorable rulings by the American Federation of Labor, including the revocation of the International Association's charter in 1912, ended this jurisdictional battle, but other jurisdictional issues would continue to challenge the union. New disputes arose over the construction of chemical plants and other manufacturing and service establishments that required extensive piping systems. Large volumes of newer types of pipefitting installation in the shift from World War I wartime industries to peacetime construction caused considerable difficulties. Jurisdictional problems also developed with other national unions, but the United Association retained jurisdiction over important, growing areas of work like construction of industrial plants, public utilities, petroleum facilities and residential buildings. In the first half of the century, the United Association moved to formalize apprenticeship training programs, including making a five-year apprenticeship mandatory in 1921, and in 1938 holding that all apprentices be members of the United Association and attend related training classes. Its National Plumbing Apprenticeship Plan of 1936 was the first set of standards governing apprenticeship to win approval of the federal government. In the Depression, United Association membership fell from its 1929 peak of 60,000 to 26,000 by 1933. After several constitutional changes through the years, the 1946 convention changed the name of the organization to its present name: The United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada. Throughout World War II and after, the United Association made considerable gains in membership and prestige. Between 1940 and 1954 membership surged from 60,000 to 240,000 with veterans entering the skilled craftsmen field. United Association member George Meany was elected in 1952 to be president of the newly formed AFL-CIO and was to provide a shaping force in the American labor movement until his death in 1980. The New Frontier of President John F. Kennedy and Great Society of President Lyndon Johnson were movements supported by the United Association. With expanded training programs beginning in 1956, the UA was able to meet the demands of accelerated construction activity in the 1960s. With the increased work the slogan, "There is no substitute for UA skilled craftsmen" became widespread throughout the industry.

The United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada, commonly known as the United Association (UA), is a labor union which represents workers in the plumbing and pipefitting industries in the United States and Canada.

n of new electrical components or the maintenance and repair of existing electrical infrastructure. Electricians may also specialize in wiring ships, airplanes, and other mobile platforms, as well as data and cable lines. Terminology Electricians were originally people who demonstrated or studied the principles of electricity, often electrostatic generators of one form or another. In the United States, electricians are divided into two primary categories: lineperson, who work on electric utility company distribution systems at higher voltages, and wiremen, who work with the lower voltages utilized inside buildings. Wiremen are generally trained in one of five primary specialties: commercial, residential, light industrial, industrial, and low-voltage wiring, more commonly known as Voice-Data-Video, or VDV. Other sub-specialties such as control wiring and fire-alarm may be performed by specialists trained in the devices being installed, or by inside wiremen. Electricians are trained to one of three levels: Apprentice, Journeyperson, and Master Electrician. In the US and Canada, apprentices work and receive a reduced compensation while learning their trade. They generally take several hundred hours of classroom instruction and are contracted to follow apprenticeship standards for a period of between three and six years, during which time they are paid as a percentage of the Journeyperson's pay. Journeymen are electricians who have completed their Apprenticeship and who have been found by the local, State, or National licensing body to be competent in the electrical trade. Master Electricians have performed well in the trade for a period of time, often seven to ten years, and have passed an exam to demonstrate superior knowledge of the National Electrical Code, or NEC. Service electricians are tasked to respond to requests for isolated repairs and upgrades. They have skills troubleshooting wiring problems, installing wiring in existing buildings, and making repairs. Construction electricians primarily focus on larger projects, such as installing all new electrical system for an entire building, or upgrading an entire floor of an office building as part of a remodeling process. Other specialty areas are marine electricians, research electricians and hospital electricians. "Electrician" is also used as the name of a role in stagecraft, where electricians are tasked primarily with hanging, focusing, and operating stage lighting. In this context, the Master Electrician is the show's chief electrician. Although theater electricians routinely perform electrical work on stage lighting instruments and equipment, they are not part of the electrical trade and have a different set of skills and qualifications from the electricians that work on building wiring. In the film industry and on a television crew the head electrician is referred to as a Gaffer. Electrical contractors are businesses that employ electricians to design, install, and maintain electrical systems.

Australia An electrician's license entitles the holder to carry out all types of electrical installation work in Australia without supervision. However, to contract, or offer to contract, to carry out electrical installation work, a licensed electrician must also be registered as an electrical contractor. Under Australian law, electrical work that involves fixed wiring is strictly regulated and must almost always be performed by a licensed electrician or electrical contractor. A local electrician can handle a range of work including air conditioning, light fittings and installation, safety switches, smoke alarm installation, inspection and certification and testing and tagging of electrical appliances. To provide data, structured cabling systems, home automation & theatre, LAN, WAN and VPN data solutions or phone points, an installer must be licensed as a Telecommunications Cable Provider under a scheme controlled by Australian Communications and Media Authority Electrical licensing in Australia is regulated by the individual states. In Western Australia, the Department of Commerce tracks licensee's and allows the public to search for individually named/licensed Electricians. Currently in Victoria the apprenticeship lasts for four years, during three of those years the apprentice attends trade school in either a block release of one week each month or one day each week. At the end of the apprenticeship the apprentice is required to pass three examinations, one of which is theory based with the other two practically based. Upon successful completion of these exams, providing all other components of the apprenticeship are satisfactory, the apprentice is granted an A Class licence on application to Energy Safe Victoria (ESV). An A Class electrician may perform work unsupervised but is unable to work for profit or gain without having the further qualifications necessary to become a Registered Electrical Contractor (REC) or being in the employment of a person holding REC status. However, some exemptions do exist. In most cases a certificate of electrical safety must be submitted to the relevant body after any electrical works are performed. Safety equipment used and worn by electricians in Australia (including insulated rubber gloves and mats) needs to be tested regularly to ensure it is still protecting the worker. Because of the high risk involved in this trade, this testing needs to be performed regularly and regulations vary according to state.

rapid advances in fabrication technology leading to the exponential growth in semiconductor device production, known as Moore's law that has persisted over the past six or so decades. The industry's annual semiconductor sales revenue has since grown to over $481 billion, as of 2018. In 2010, the semiconductor industry had the highest intensity of Research & Development in the EU and ranked second after Biotechnology in the EU, United States and Japan combined. The semiconductor industry is in turn the driving force behind the wider electronics industry, with annual power electronics sales of £135 billion ($216 billion) as of 2011, annual consumer electronics sales expected to reach $2.9 trillion by 2020, tech industry sales expected to reach $5 trillion in 2019, and e-commerce with over $29 trillion in 2017. In 2019, 32.4% of the semiconductor market segment was for networks and communications devices. In 2021, the sales of semiconductors reached a record $555.9 billion, up 26.2%, with sales in China reaching $192.5 billion, according to the Semiconductor Industry Association. A record 1.15 trillion semiconductor units were shipped in the calendar year.

Industry structure The global semiconductor industry is dominated by companies from the United States, Taiwan, South Korea, Japan and the Netherlands, with Israel and Germany having significant presence in the field. Unique features of the industry include continuous growth but in a cyclical pattern with high market fluctuation over the short run. While the current 20-year annual average growth of the semiconductor industry is on the order of 13%, this has been accompanied by equally above-average market volatility, which can lead to significant if not dramatic cyclical swings. This has required the need for high degrees of flexibility and innovation in order to constantly adjust to the rapid pace of change in the market as many products embedding semiconductor devices often have a very short life cycle. At the same time, the rate of constant price-performance improvement in the semiconductor industry is staggering. As a consequence, changes in the semiconductor market not only occur extremely rapidly but also anticipate changes in industries evolving at a slower pace. The semiconductor industry is widely recognized as a key driver and technology enabler for the whole electronics value chain. Prior to the 1980s, the semiconductor industry was vertically integrated. Semiconductor companies both designed and manufactured chips in their own facilities. In many cases, this included inventing new processes, refining and purifying source chemicals and silicon wafers, and even manufacturing equipment, like furnaces, lithography tools and etchers. These companies also carried out the assembly and testing of their chips. Over time, many of these functions were outsourced, such that today semiconductor manufacturers rely on a complex supply chain to provide wafers, high-purity source chemicals, and processing equipment. Further, starting with LSI in 1969, the industry has seen the emergence of Fabless Semiconductor Companies that focus solely on chip design and rely on other companies to manufacture their designs. Initially, these other companies were integrated device manufacturers (IDMs), companies that also designed and manufactured their own products, and thus were often competitors of the Fabless companies. But, by the mid-1980's TSMC and UMC emerged as foundries, specializing solely in the manufacture of other companies' designs. Today, much of the industry is based on the foundry model, which consists of semiconductor fabrication plants (foundries) and integrated circuit design operations, each belonging to separate companies or subsidiaries. Some companies, known as integrated device manufacturers, both design and manufacture semiconductors. The foundry model has resulted in consolidation among foundries. As of 2021, only three firms are able to manufacture the most advanced semiconductors: TSMC of Taiwan, Samsung of South Korea, and Intel of the United States. Part of this is due to the high capital costs of building foundries. TSMC's latest factory, capable of fabricating 3 nm process semiconductors and completed in 2020, cost $19.5 billion. Intel is considering outsourcing some production to TSMC. It currently can only produce 10 nm semiconductors, while TSMC and Samsung can both produce 5 nm.

A trade union (British English) or labor union (American English), often simply referred to as a union, is an organization of workers whose purpose is to maintain or improve the conditions of their employment, such as attaining better wages and benefits, improving working conditions and safety standards, establishing complaint procedures, developing rules governing the status of employees (including rules on promotions and just-cause conditions for termination), and protecting and increasing the bargaining power of workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called union dues. The union representatives in the workforce are usually made up of workplace volunteers who are often appointed by members through internal democratic elections. The trade union, through an elected leadership and bargaining committee, bargains with the employer on behalf of its members, known as the rank and file, and negotiates labour contracts (collective bargaining agreements) with employers. Unions may organize a particular section of skilled or unskilled workers (craft unionism), a cross-section of workers from various trades (general unionism), or an attempt to organize all workers within a particular industry (industrial unionism). The agreements negotiated by a union are binding on the rank-and-file members and the employer, and in some cases on other non-member workers. Trade unions traditionally have a constitution which details the governance of their bargaining unit and also have governance at various levels of government depending on the industry that binds them legally to their negotiations and functioning. Originating in the United Kingdom, trade unions became popular in many countries during the Industrial Revolution when employment (rather than subsistence farming) became the primary mode of earning a living. Trade unions may be composed of individual workers, professionals, past workers, students, apprentices or the unemployed.

British trade unions were finally legalized in 1872, after a Royal Commission on Trade Unions in 1867 agreed that the establishment of the organizations was to the advantage of both employers and employees. This period also saw the growth of trade unions in other industrializing countries, especially the United States, Germany and France. In the United States, the first effective nationwide labour organization was the Knights of Labor, in 1869, which began to grow after 1880. Legalization occurred slowly as a result of a series of court decisions. The Federation of Organized Trades and Labor Unions began in 1881 as a federation of different unions that did not directly enrol workers. In 1886, it became known as the American Federation of Labor or AFL. In Germany, the Free Association of German Trade Unions was formed in 1897 after the conservative Anti-Socialist Laws of Chancellor Otto von Bismarck were repealed. In France, labour organisation was illegal until the 1884 Waldeck Rousseau laws.

Politics In the United States, the weakening of unions has been linked to more favourable electoral outcomes for the Republican Party. Legislators in areas with high unionization rates are more responsive to the interests of the poor, whereas areas with lower unionization rates are more responsive to the interests of the rich. Higher unionization rates increase the likelihood of parental leave policies being adopted. Republican-controlled states are less likely to adopt more restrictive labour policies when unions are strong in the state. Research in the United States found that American congressional representatives were more responsive to the interests of the poor in districts with higher unionization rates. Another 2020 American study found an association between US state level adoption of parental leave legislation and trade union strength. In the United States, unions have been linked to lower racial resentment among whites.

Boise (locally also ) is the capital and most populous city in the U.S. state of Idaho. It is the county seat of Ada County. The population of the city was 235,685 at the 2020 census. 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 miles (66 km) east of the Oregon border and 110 miles (177 km) north of the Nevada border. Downtown Boise's elevation is 2,704 feet (824 m) above sea level. Boise is home to major employers in the technology, manufacturing, and service sectors, including companies such as Micron Technology and Hewlett-Packard.

...that the military should continue killing Indians 'until the last Indian in the Territories was either on his reservation or enriched the sagebrush with his decaying carcass.' ...if the Indians refused to move there, 'they will be killed or put on the reservation by force, and certainly shot if they don't stay there.' Furthermore, the editor continues, 'The idea that the Indians have any right to the soil is ridiculous. ...They have no more rights to the soil of the Territories of the United States than wolves or coyotes...' This would be our plan of establishing friendship upon an eternal basis with our Indians: Let all the hostile bands of Idaho Territory be called in (they will not be caught in any other manner) to attend a grand treaty; plenty of blankets and nice little trinkets distributed among them; plenty of grub on hand; have a real jolly time with them; then just before the big feast put strychnine in their meat and poison to death the last mother's son of them. 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 the 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. Incorporation and growth 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 to 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 Americans with Disabilities Act of 1990 (ADA) (42 U.S.C. § 12101) is a civil rights law that prohibits discrimination based on disability. It affords similar protections against discrimination to Americans with disabilities as the Civil Rights Act of 1964, which made discrimination based on race, religion, sex, national origin, and other characteristics illegal, and later sexual orientation and gender identity. In addition, unlike the Civil Rights Act, the ADA also requires covered employers to provide reasonable accommodations to employees with disabilities, and imposes accessibility requirements on public accommodations. In 1986, the National Council on Disability had recommended the enactment of an Americans with Disabilities Act and drafted the first version of the bill which was introduced in the House and Senate in 1988. A broad bipartisan coalition of legislators supported the ADA, while the bill was opposed by business interests (who argued the bill imposed costs on business) and conservative evangelicals (who opposed protection for individuals with HIV). The final version of the bill was signed into law on July 26, 1990, by President George H. W. Bush. It was later amended in 2008 and signed by President George W.

Heating, ventilation, and air conditioning (HVAC ) systems regulate temperature, humidity, and indoor air quality in vehicles and buildings. They are designed to provide thermal comfort and to control airborne contaminants through heating, cooling, ventilation, filtration, and humidity control. HVAC design considerations include energy efficiency, indoor air quality, maintenance, and environmental impact, particularly in green building projects. In building design, mechanical, electrical, and plumbing engineers may integrate HVAC systems with other building systems (i.e.

nce, and environmental impact, particularly in green building projects. In building design, mechanical, electrical, and plumbing engineers may integrate HVAC systems with other building systems (i.e. air-source heat pump water heaters) and use energy modeling to evaluate performance and operating costs. Summary The three major functions of heating, ventilation, and air conditioning are intertwined. HVAC systems can provide ventilation and maintain pressure relationships between spaces.

A plumber is a tradesperson who specializes in installing and maintaining systems used for potable (drinking) water, hot-water production, sewage and drainage in plumbing systems. History The origin of the word "plumber" dates from the Roman Empire. Roman roofs used lead in conduits and drain pipes and some were also covered with lead; lead was also used for piping and for making baths. The Latin for lead is plumbum.

Years of training and/or experience are needed to become a skilled plumber; some jurisdictions also require that plumbers be licensed. Common plumbing tasks and skills include: Reading drawings and specifications, to determine the layout of water supply, waste, and venting systems Detecting faults in plumbing appliances and systems, and correctly diagnosing their causes Installing, repairing and maintaining domestic, commercial, and industrial plumbing fixtures and systems Locating and marking positions for pipe connections, passage holes, and fixtures in walls and floors Measuring, cutting, bending, and threading pipes using hand and power tools or machines Joining pipes and fittings together using soldering techniques, compression fittings, threaded fittings, solvent weld, crimp and push-fit fittings. Testing pipes for leaks using air or water pressure gauges Paying attention, in all work undertaken, to legal regulations and safety issues Ensuring that all safety standards and building regulations are met.

The Associated General Contractors of America (AGC) is a trade association in the United States construction industry, with headquarters in Arlington, Virginia. History The AGC was founded in November, 1918 to address problems identified during World War I. In 1912, the federal government asked the U.S. Chamber of Commerce to bring all industry associations together under its umbrella. AGC's founding members attended a Chamber-led meeting in Atlantic City, New Jersey in the spring of 1918, but felt it was geared too much toward subcontractors. In the fall of 1918, the group that would later become the founding members met in Chicago and subsequently formed AGC. The group's first president was Daniel A.

Membership AGC represents over 6,500 of America’s general contractors, and over 9,000 specialty-contracting firms.

105, which by 2025 was estimated to have risen to 275,123, making it the second-most populous county in Idaho. The county seat is Caldwell, and its largest city is Nampa. Canyon County is part of the Boise metropolitan area. History Hudson's Bay Company established Fort Boise in 1834 near what is now Parma, but abandoned it in 1855. Emigrants traveled through Canyon County on the Oregon Trail. Discovery of gold in the Boise Basin in 1862 brought settlement to the region again. The lower Boise River was fully contained within Boise County from 1863 until the formation of Ada County in 1864. Settlement of the lower Boise River west of Boise City was limited prior to the completion of the Oregon Short Line Railroad. Middleton was the first European settlement of Canyon County, starting in 1863. The 1870 Census for Ada County listed 76 residents of the Boise Valley, excluding Boise City and the 1880 Census listed 44 residents at Middleton. The arrival of the railroad at Caldwell led to the establishment of a town there as of August 1883. Businessmen James A. McGee and Alexander Duffes filed the plat for nearby Nampa in 1886. Parma was settled around the same time, with the Old Fort Boise post office being moved to the town's location; it was incorporated in 1904. Ada County established precincts for each of the settlements with a combined 1890 Census population of 2,311. Significant settlement of Greenleaf and Notus started around 1904 with the two settlements listed as precincts at the 1910 census. Notus was incorporated in 1921 while Greenleaf was incorporated prior to 1980. Melba was incorporated in 1912 while Wilder was incorporated in 1919. The City of Star annexed a portion of territory in northeast Canyon County prior to 2007, becoming the county's ninth incorporated city. The majority of Star is located within Ada County. The Idaho Legislature created Canyon County from Ada County in an act approved March 7, 1891, effective at the November 26, 1892, election. Caldwell was established as the county seat. The county originally contained all of Canyon and Payette counties and part of Gem; Gem County formed in 1915 and Payette County in 1917.

Eagle is a city in Ada County, Idaho, ten miles (16 km) northwest of downtown Boise. The population was 30,346 at the 2020 census. History 19th century Eagle Island in Idaho was settled in 1863 by Truman Coe Catlin, who later shifted from crop farming to dairy farming, starting the island's dairy tradition. He also pioneered irrigation in the area by constructing a wide irrigation ditch. The most notable early community developer was Thomas Hugh Aiken, a Canadian surveyor, who helped establish the Eagle community in the 1870s.

Parks and recreation The city features numerous parks, including Arboretum Park, Friendship Park, Heritage Park, Orval Krasen Park, Reid W. Merrill Sr. Community Park, and Stephen C. Guerber Park, among others. The Parks and Recreation department offers youth sports leagues, camps, special events (such as Eagle Fun Days), and maintains extensive trails. Nearby Eagle Island State Park provides a swimming beach, trails, disc golf, and winter sports. Education Most of Eagle is in the West Ada School District, with a small portion in the Boise School District.

20th century The Eagle Fish Hatchery, established in the late 1940s in Idaho, was originally part of a trout program until the 1980s. In 1991, it was restructured to support the conservation of Snake River sockeye salmon, an endangered species listed that year. The hatchery's mission shifted to preserving the species and its genetic diversity through the development of eight broodstocks derived from smolts, anadromous adults, and residual populations. It also houses the IDFG Eagle Fish Health Laboratory.
