Lower Southampton Township is a township of the second class located in lower Bucks County.  The Township encompasses 6.6 square miles, being bordered on the east by Bensalem Township, on the north by Northampton Township, on the west by Upper Southampton Township and Lower Moreland Township (Montgomery County), and on the south by the City of Philadelphia.  Principal unincorporated communities within the Township are Feasterville, Trevose Heights, and parts of Oakford and Trevose.  Feasterville, the approximate geographical center of the Township, is approximately 17 miles from center city Philadelphia and approximately 14 miles from Trenton, New Jersey.

Until the late 1950’s, the Township was primarily rural in character, at which time a transition in land use from rural-agricultural to suburban and single family residential began.  The Township has evolved largely into a commuter-oriented  community, based to a great extent on employment opportunities in both the Philadelphia and Trenton labor markets.
