is a city in Clark County, Nevada, United States. It is approximately 20 miles from the City of Las Vegas. As of the 2000 census the population was 14,966, with a 2006 estimated population of 15,005.
Boulder City was originally built in 1932 by the Bureau of Reclamation as housing for workers who were building Hoover Dam (the original name of the dam was Boulder Dam). It was designed by landscape architect Saco Rienk DeBoer. Alcohol sales, membership in unions and all forms of gambling were prohibited in the city. The Bureau did not relinquish control of the city until 1958. Boulder City was officially incorporated on January 4, 1960, and the city council selected pharmacist Robert N. Broadbent as the first mayor.
The city charter, approved by the residents, prohibited gambling within the city limits. This provision still exists, making Boulder City one of only two locations in Nevada where gambling is illegal (the other is the town of Panaca). The Hacienda Hotel and Casino, which has a Boulder City mailing address, is located on a parcel of private land within the boundaries of the Lake Mead National Recreation Area, and is not within city limits.
