Meridian & Kuna

The booming southern suburbs of Ada County, where Idaho's fastest-growing city — Meridian (pop. ~143,000) — sprawls along I-84 and Eagle Road. Kuna, once a sleepy farming town 18 miles southwest of downtown Boise, has exploded past 31,000 residents with new master-planned subdivisions. Together they form the metro's commercial and residential engine, with big-box retail corridors, top-rated schools, and easy freeway commutes.
