The city was named after Sergeant Charles Floyd, the only member of the Lewis and Clark Expedition to die on the journey. Sergeant Bluff was incorporated on May 2, 1904. Sergeant Bluff is located just off of Interstate 29 and in the heart of industrial and residential growth. We are very excited about the peaceful and relaxing environment that our city has to offer our residents. We hope that you will find Sergeant Bluff to be progressive, yet small enough to get to know people as individuals.
