Incorporated on June 9, 1885, North Plainfield is a densely populated Somerset County borough that packs a population of more than 22,000 residents into just 2.82 square miles along the northern edge of the Raritan Valley. That compact scale is part of what sets it apart from sprawling suburban neighbors like Warren Township — here, walkability and a genuine sense of place come standard. The Washington Park Historic District, listed on the National Register of Historic Places in 1987, anchors the borough's architectural identity with well-preserved late-19th-century streetscapes that larger, faster-growing towns in the region simply cannot replicate.
