The BUBBAs!

The BUBBAs!

The Best Urban BMP in the Bay Awards (BUBBA) is a one-of-a-kind contest that recognizes the best urban BMPs that have been installed in the Chesapeake Bay watershed. It’s a great opportunity to share our new techniques and accomplishments (and maybe win a little cash!) The contest is open now through April 5, 2019. Submit your project today!

The Chesapeake Stormwater Network advocates for reform of federal, state and local laws, permits, regulations and design manuals to promote more sustainable stormwater management in the Chesapeake Bay.
