Endangered Historic Structures

Valley Forge National Historical Park has eighty-one historic structures within its boundaries. Twelve of these structures date back to the time of the Encampment. These buildings are at risk of flooding, erosion, and falling trees. These issues will become more common with the increasing frequency and intensity of storms. The Pennsylvania Climate Impact Assessment Report states that it is likely that Pennsylvania's precipitation climate will become more extreme in the future. This will mean longer dry periods and shorter, more intense periods of rain or snow.
