Extreme Event Adaptation

Stormwater Management Strategies

for Extreme Events

Intentional design strategies that help mitigate the threat of high-volume, high-velocity stormwater runoff from heavy precipitation events:

Low-Impact Development (LID)
Rain Gardens, Permeable Pavement, Green Roofs, Ecosystem Restoration
Gray Infrastructure
Upgraded Drainage Systems, Retention and Detention Basins, Pumping Stations​

Integrated Approaches
Hybrid solutions include concrete curbs and infrastructure to direct excess water into vegetated swales or rain gardens.
Proactive & Advanced Strategies
Forecasting and Monitoring (e.g., weather radars), Regular System Updates, Smart Stormwater Management ​
