Pennsylvania’s aging levees are under pressure from scarce funding and severe weather
Many levees built in the mid-1900s do not offer enough protection for today’s storms, and small rural communities in particular struggle to afford needed upgrades.
Pennsylvania's aging levees face challenges from funding shortages and intense weather. Over 180 levees protect 158,000 residents and $26.2 billion in property. However, these structures are outdated and costly to maintain. Constructed between 1950 and 1970, they exceeded their typical 50-year design life years ago and are now managed by local communities with limited resources.
Extreme weather, such as the heavy rains from Hurricane Ida in 2021, puts additional strain on these aging levees. Flood risk considers hazard, exposure, and vulnerability, which all evolve over time. Recent data shows increased rainfall intensity in Pennsylvania, and only about 15% of the state's levees are accredited by FEMA. With funding scarce and weather patterns changing, Pennsylvania's aging levees require urgent attention and investment.
