New Castle Zoning & Land Use Guide
Key Zoning Facts
New Castle Zoning Overview
New Castle is the county seat of Lawrence County, Pennsylvania, located in the Shenango Valley of western Pennsylvania at the confluence of the Shenango River and Neshannock Creek. With a population of approximately 21,974, New Castle has a rich industrial history in tin plate and steel manufacturing, earning it the historical nickname "Tin Capital of the World." The city is also known for its distinctive chili culture and fireworks industry. Like many western Pennsylvania industrial cities, New Castle has faced population decline and economic restructuring.
The city's zoning is managed by the Planning and Zoning Department. New Castle's land use features a traditional downtown centered on the public square, dense residential neighborhoods, commercial corridors, and former industrial sites along the rivers and railroads. The city continues to pursue economic development and downtown revitalization.
