Section 3 -- BMP Selection Guidelines (for Construction and Permanent BMP Design)
Selecting the right BMPs for expected rain events and subsequent runoff rates cannot be over emphasized in BMP effectiveness. Go to ‘BMP Selection Quick Links’ in this Section to find recommended BMPs for specific projects.

Section 4 -- Sediment Control
When storm events cause sediment and contaminant laden waters to begin to migrate off-site, these temporary BMPs help keep contaminants on-site, preventing them from entering the stormwater system and moving into local streams and lakes.

Section 10 -- Limited Space Devices (and other Proprietary Devices)
These permanent devices function in limited space. However, based on pollutants of concern, expected runoff flow rates and maintenance access, careful consideration must be given to selection of the appropriate device.  (Note: these are proprietary units. Inclusion in this manual does NOT constitute an endorsement of these devices nor vouch for their pollutant removal rates.)
