Bioretention

Perfecting Bioretention. A key role you can play in the Network is to provide your perspectives and help develop updated Bay-wide design specifications for innovative stormwater practices. Our first target is bioretention, which hasn’t been over-hauled in more than a decade, despite a flood of new research and a lot of anecdotal reports on installation problems.

Bioretention is beginning to get a bad name as a result of poor construction and maintenance in some communities. The actual installation of bioretention areas is much more sophisticated and complex than many bioretention advocates admit. To improve the bioretention product, CSN has produced a short slide show outlining the proper construction sequence to install a good bioretention area. The show is primarily geared toward designers, plan reviewers and contractors.
