The increased rainfall and sewer overflows have caused significant damage to properties, particularly in low-lying neighborhoods in Pittsburgh and Allegheny County. Communities in the Mon Valley, such as McKees Rocks and Rankin, are disproportionately affected due to their location in flood-prone areas and economic challenges. Flooding in these areas often leads to sewage backups, posing severe health risks and financial burdens for residents. The National Weather Service has reported a 28% increase in hourly rainfall intensity in Pittsburgh since 1970, with extreme rainfall events in the northeastern U.S. rising by 71% between 1958 and 2012 (Tech Times, 2026).
