 The town that was to become Port Orchard was originally platted in 1886 by Frederick Stevens, who named the new location after his father, Sidney.The town of Sidney was incorporated September 15, 1890, and was the first in Kitsap County to be both platted and incorporated.Shortly thereafter, the U.S. Navy sought a suitable location for another installation on the West Coast, and found it with the assistance of Sidney's residents in Orchard Bay (this installation would later become the Puget Sound Naval Shipyard in Bremerton).
