Soil & Terrain Characteristics

Armstrong County features dissected Allegheny Plateau terrain with soils derived from Pennsylvanian sandstone, shale, and coal measures. Hilltop soils tend to be better drained, while valley and hillside soils are heavier and more poorly drained. Coal mining has disturbed natural soil profiles in many areas. The Allegheny and Redbank Creek valleys have deeper alluvial deposits.

County-Specific Considerations

Armstrong County has an extensive coal mining history that affects soil conditions and water quality. Acid mine drainage impacts many streams and can affect well water. Kittanning and Ford City boroughs have municipal sewer, but most rural areas rely on on-lot systems. The Allegheny River corridor provides recreational opportunities but creates flood risk for adjacent properties.
