Columbia County, Pennsylvania
Columbia County lies along the North Branch Susquehanna River in central Pennsylvania, anchored by Bloomsburg, the state's only incorporated town, and by Berwick downstream. Commonwealth University's Bloomsburg campus, manufacturing reinvestment in Berwick and the Route 11 retail corridor through Scott Township drive activity, while the river's floodway governs what can be built on the valley floor.
