Ada County, Administrative county in southwestern Idaho, US
Ada County is an administrative division in southwestern Idaho that combines urban areas, farmland, and natural spaces into one region. The Boise River runs through the northern portion, shaping both the landscape and where people choose to live and work.
The county was created in 1864 during territorial expansion in the region. It took its name from Ada Riggs, a member of the founding community who helped shape early settlement in the area.
The county maintains multiple educational institutions, including the College of Western Idaho and four school districts serving its population of over 500,000 residents.
Government offices and public services are centered in Boise, where you can find information about local regulations and community resources. The region offers multiple access points to outdoor areas and recreational facilities scattered throughout its landscape.
The region includes portions of two major conservation areas that protect different habitats and wildlife corridors across the landscape. These spaces reveal how human settlement and natural preservation coexist within the same administrative boundaries.
