The community of Yardley Borough is slightly less than a square mile along the Delaware River in Lower Bucks County. Yardley was founded by William Yardley, who emigrated to America in 1682 with his family. William Yardley and his family died in 1693, possibly of smallpox. A nephew, Thomas Yardley, came to America to settle the estate and never returned to England. He opened a ferry line which started operating in 1710. This was an important link between West Jersey and Philadelphia. The Yardley family occupied the land for more than 150 years.

Today Yardley combines the best that small town living has to offer with the convenience of modern suburban living. Accessible to Philadelphia, Princeton, and New York via road and rail, Yardley's population has remained stable over the years, while mushrooming residential and commercial growth in surrounding Lower Makefield Township has nearly doubled the area's size since 1980. Lake Afton, at Main Street and Afton Avenue, is a refuge for migrating ducks, and many of the Borough's automobiles sport "I Brake for Ducks in Yardley" bumper stickers. The lake is also a favorite spot for ice skating during the winter
