It lies within the regional context of Georgetown, Delaware, Lewes, Delaware, Rehoboth Beach, Delaware, and the industrial corridors leading toward Dover, Delaware and the Delaware Bay.

History

Portsmouth occupies land once inhabited by the indigenous Nanticoke people and later influenced by colonial settlement patterns associated with William Penn and the proprietary era of Province of Pennsylvania and Delaware. Proximity to Broad Creek (Delaware), Nanticoke River, and the Delaware Bay made the area relevant to maritime activities tied to colonial America, American Revolutionary War logistics, and regional trade networks that included ports like Lewes, Delaware and New Castle, Delaware. In the 19th century the growth of Delaware Division of the Pennsylvania Railroad and agricultural markets connected Portsmouth to grain and timber flows toward Philadelphia, Pennsylvania and Baltimore, Maryland. The 20th century brought infrastructural change as federal policies such as the Federal Aid Highway Act of 1956 and regional planning initiatives shifted traffic patterns toward Interstate 95 corridors, while local land use remained anchored in farming, aquaculture, and small‑town commerce tied to Sussex County, Delaware developments.
