About the Township

Thornbury Township, Chester County was organized in 1687 when just six families occupied the land. Prior to its founding, the Delaware Indians traversed the beautiful rolling landscape. Both branches of Chester Creek meander through Thornbury and flow to join the Delaware river. The Battle of Brandywine during the Revolutionary War was partially fought in Thornbury Township. It was one of Thornbury’s citizens, Squire Thomas Cheyney, who informed Washington of the approach of the British.

Today, it is a charming area with winding country roads. It has evolved from a rural area to suburban residential neighborhoods. Thornbury Township has seen tremendous growth over the last decade and only a few key parcels and several smaller parcels remain undeveloped. Our current challenge is to take strong municipal action to preserve our Township’s key remaining resources while regulating new development in a way that limits its impact on our existing residents.


Township Mission Statement

The Board of Supervisors of Thornbury Township, Chester County, through leadership, commitment and prudent spending will:

Ensure that Township residents are provided with a high quality water supply in sufficient quantities to meet present as well as future needs;

Review, update and improve the Township’s Emergency Operations Plan including police, fire, and ambulance services;
