Why this site exists

Public records, made readable for the people who live here.

This platform brings together active residential development applications, Pennsylvania DEP stormwater permits, and the fiscal relationship between developer fees and the public infrastructure that serves Indiana Township residents.

It is an independent civic education resource — not affiliated with Indiana Township government. Data is sourced from public PA DEP records, township meeting minutes, and Pennsylvania DCED Annual Financial Reports.

The watershed connection

What happens here flows to Pittsburgh's drinking water.

4Impaired waterways
1Major river affected
8Stream corridors at risk

Indiana Township's stormwater drains through a network of streams — several of them already listed as impaired by the Pennsylvania DEP — before reaching the Allegheny River, which supplies drinking water to the greater Pittsburgh metropolitan area.

Every new rooftop, road, and parking lot adds impervious surface. More impervious surface means more runoff, more pollutant loading, and more strain on a watershed this township is legally obligated to protect under NPDES permit PAI136101.

The Emmerling legacy

A WWII veteran's land gift still protects the watershed today.

In 1974, Dr. John F. Emmerling and his wife Nancy deeded 10 acres of ancestral family land to Indiana Township — establishing the core of Emmerling Park along the Little Deer Creek corridor. In 2025, that protected footprint grew by 266 acres through a partnership with the Allegheny Land Trust and the Pennsylvania Game Commission.

This platform's civic mission is grounded in that same spirit of community stewardship.
