About this map

Delaware Bay defines the western edge of this coastal landscape, where the Fishing Creek Shoal and Delaware Shore Channel separate the open water from a string of bayside settlements. Towns like Villas and Del Haven sit nestled between the shoreline and the interior lowlands of Middle and Lower townships. The map illustrates a transitional period of development, with purple-tinted areas showing the growth of coastal neighborhoods through the early 1970s.

Inland, the Pennsylvania-Reading Seashore Lines provides a critical rail link near the hub of Rio Grande. Local infrastructure is prominent, from the County Airport and County Mosquito Commission to the Fishing Creek Sch. Genealogists and historians can trace smaller communities and named locales such as Nummytown, Erma Park, and Sally Marshall Crossing, along with agricultural and natural landmarks like Potato Island and Fulling Mill Stream.
