Oakdale Borough was incorporated in 1892.[19] On May 18, 1918 a TNT explosion in a local chemical factory killed 200 people.[20] On September 17, 2004, Oakdale was devastated by a flood resulting from the rain brought by the remnants of category 5 Hurricane Ivan. The downpour from Ivan followed a steady rain that had covered the Allegheny County area from category 4 Hurricane Frances, which struck the area just 10 days before Ivan hit.[21] The flooding caused a large-scale evacuation of the community, and brought Red Cross volunteers and National Guard members to the area in an effort to control the confusion. The flooding destroyed businesses, many of which never reopened, and displaced many residents whose homes were condemned.
