Blood, Trauma, and Biohazard Cleanup in Collingdale, PA

Collingdale was carved out of Darby Borough and incorporated as its own borough on December 23, 1891, after local freeholders petitioned the Delaware County courts for a separate municipality.

The 2020 census counted 8,908 people in Collingdale, and Census QuickFacts counts about 3,739 households in the borough.

Collingdale's population exploded with railroad-era development, jumping from just 603 residents in 1900 to 7,857 by 1930, and it peaked at 10,605 in 1970.

Almost half of Collingdale's roughly 0.9 square miles is occupied by four cemeteries, with most of the remaining land densely residential.

One of those cemeteries, Eden Cemetery, is a historic African American burial ground where contralto Marian Anderson, physician Rebecca Cole, and civil rights activist Octavius Catto are buried; it is listed on the National Register of Historic Places.

Collingdale's longtime mayor Frank Kelly served 12 consecutive terms over 47 years in office, the longest mayoral tenure in Pennsylvania history.

U.S. Route 13 crosses the eastern corner of Collingdale, and MacDade Boulevard is the borough's principal commercial street.
