Bioretention Design Adaptations for a Changing Climate

Bioretention systems, when enhanced with design modifications like controlled under drains and internal overflows, can reduce peak flows during intense storms and improve drainage. While green infrastructure can help manage stormwater and localized flooding, its effectiveness is highly dependent on site-specific conditions and often requires integration with conventional drainage systems. Key considerations include the potential impacts of increased storm frequency and intensity due to climate change, which could affect bioretention system performance and increase maintenance needs. The session also highlights the importance of future-proofing designs by increasing surface storage and incorporating adaptive features like automated controls. As well as the challenges posed by sea level rise and the need for proactive planning to ensure long-term system functionality. These insights aim to guide the implementation of green infrastructure practices that can better handle future storm events and contribute to more resilient urban environments.
