More About Ada County

Ada County was established on December 22, 1864, making it the seventh county formed in the state. The county was named for Ada Riggs, the first white child born in the area and the daughter of H.C. Riggs, one of the founders of Boise.

The county seat is Boise, which became the state capital of Idaho in 1865. It is the most populous city in the State of Idaho and has been given the nickname "The City of Trees." Its name was given by French-Canadian trappers who first explored the area after crossing the desert plains of the territory. Upon finding green trees at the site, primarily cottonwoods along the river, they named it "boise," meaning wooded.

Interesting Facts:

Ada County, located in southwestern Idaho, is the state's most populated county and ranks thirty-first in area.  Approximately 45 percent of the county is federally owned.  Its diversified economy forms the regional trade center.  Annual average total civilian employment grew 40.4 percent from 1990 to 1997. 

Ada and Canyon counties comprise the Boise Metropolitan Statistical Area (MSA).   Ada County is home to the state capital and to Boise State University, both located in Boise, Idaho's largest city.  Albertsons, Boise Cascade Corporation, Micro Technology, and Morrison-Knudsen are headquartered in Boise, as is one of Hewlett-Packard's most significant research and development sites.  Points of interest include the Snake River Birds of Prey Area (south of Kuna) and the Boise River Festival, which draws hundreds of thousands of visitors annually.

The Snake River Birds of Prey area has the largest concentration of nesting raptors in North America.  The birds can be observed from March to August each year.

Underground hot springs in Boise allow many buildings and homes in the city to use geothermal heat, including the Idaho Statehouse.

Idanha HotelThe Idanha Hotel (now the Idanha Building):  Construction of the historic Idanha Hotel began in 1900. At that time, it was the most expensive building ever built in Boise. Architect Walter S. Campbell designed it in the French chateau style. With its distinctive round corner turrets, the building is a fixture of downtown Boise. It is located on the corner of 10th and Main Streets, and once had the distinction of being the state's highest building.  A major renovation of the Idanha Hotel converted its 104 hotel rooms into 53 apartment units.  The ground floor and basement are being modified to accommodate retail space.
