BUBBAs
Welcome to the Chesapeake Bay’s oldest and most prestigious stormwater contest!
The BUBBAs give stormwater practitioners across the Chesapeake Bay Watershed the opportunity to share and celebrate the work they are most proud of.
It also helps us share innovations and facilitate scalable urban stormwater management implementations—from New York to Virginia and everywhere in between.

Since 2014, CSN has hosted the BUBBAs every other year. While other low-impact development (LID) competitions focus on the design of new stormwater practices, CSN aims to recognize on-the-ground techniques being used to tackle difficult stormwater problems. Through the BUBBAs, we’re able to:
- Recognize innovators in the field who are using new and creative techniques to treat runoff and protect streams;
- Share these innovative techniques with other communities who could benefit from the lessons learned; and
- Inspire interaction among our 6,000+ member network of stormwater professionals throughout the Bay watershed and beyond.
