Worcester's Hills: Water Slides or Flood Traps?
19 Jun
Summary
- Hilly terrain accelerates water runoff, challenging aging drainage systems.
- Nature-based solutions like rain gardens are being tested to manage flooding.
- Climate change is expected to worsen localized flooding events.

Worcester's famed hilly terrain presents unique challenges for its aging stormwater management system, where water quickly flows down slopes and accumulates at the bottom.
Consultants are developing a comprehensive three-phase plan to address flooding, which is expected to intensify with climate change.
Phase two of the plan focused on detailed modeling of water flow and testing nature-based solutions, like rain gardens and bioretention swales, at sites such as Burncoat Street Preparatory School.
This approach aims to filter and store stormwater, reducing the burden on the city's inadequate pipe network.
Additionally, the city is addressing its outdated combined sewer systems in the downtown area, dating back to the 1800s, which frequently overflow during heavy rains.
Phase three will further refine flood modeling and create an interactive public display.
Investments in flood mitigation are considered crucial to avoid far more significant costs from catastrophic storm impacts in the future.
