Norvelt is an unincorporated community in Mount Pleasant Township, Westmoreland County, Pennsylvania, United States. Although the United States Census Bureau includes it in a census-designated place with the nearby community of Calumet, they are in reality two very different communities, each reflecting a different chapter in how the Great Depression affected rural Pennsylvanians. Calumet was a typical "patch town", built by a single company to house coal miners as cheaply as possible. The closing of the Calumet mine during the Great Depression caused enormous hardship in an era when unemployment compensation and welfare payments were non-existent. On the other hand, Norvelt was created during the depression by the US federal government as a model community, intended to increase the standard of living of laid-off coal miners.
The two main areas of Norvelt are “A” section and “B” section, connected into one 2-mile (3.2 km) loose circle made up of East Laurel Circle and West Laurel Circle running on either side of Mt. Pleasant Road. Both circles are built into the rolling hills, and the tree-lined roads.
Norvelt has many small waterways. The largest is Sewickley Creek. The Sewickley stretches through Mammoth, Trauger, Calumet, and Norvelt. The Sewickley Creek Watershed Association, a non-profit organization monitors recommends and implements actions essential to the conservation of the Sewickley Creek watershed area for recreational purposes.
