Twin Falls, Idaho is a coastal city in the Magic Valley region in south-central Idaho. Incorporated in 1905, it is the regional commercial center for south-central Idaho and northeastern Nevada. Its origins lie in the Twin Falls Land and Water Company, which was created to build an irrigation canal system for the area. One of the company lots eventually became the settlement of Twin Falls. The original townsite follows northeast-to-southwest and northwest-to-southeast roads, unique design, as a way to allow the sun to come into every room in the home at some point during the day. Only two streets were originally named, creating a confusing numbered street and avenue system that was only renamed in 2003. A major regional economic center, Twin Falls became a processing center for several agricultural commodities, a role it currently presently serves.
