Sinkholes in PA

Sinkholes and Stormwater

The type of land below the surface, or the geology of a place, plays a large role in how water moves underground. According to geologists and The Geological Story of Pennsylvania, a large majority of our land is made up of something called Karst geology where, in short, sheets of limestone breakdown to create underground spaces for water to be stored. These spaces can lead to sinkholes, which can affect the development of the land and flow of water.

Understanding the land forms and water flow within our watershed can help us plan and develop land for better storm water management.
