About
Rose Valley Borough is a 410-acre municipality in Delaware County incorporated in 1923, covering land that was originally part of Nether Providence Township and Middletown Township. The borough’s residential character traces to 1901, when architect William Lightfoot Price founded an intentional Arts and Crafts community on approximately 80 acres of former mill property along Ridley Creek; homes Price designed on Price’s Lane and Porter Lane remain standing today. In 2010, the U.S. Department of the Interior listed the Rose Valley Historic District — covering essentially the entire borough and encompassing 105 buildings — on the National Register of Historic Places, making exterior alterations subject to review under preservation guidelines buyers should investigate before purchase.
