Sketches A and D were adapted from Prince George's County, MD, LID IMP Guidance Document, 2002.
Sketches B and C were modified from Start at the Source as provided by Bay Area
Stormwater Management Agencies Association and illustrator Patric Dawe.
Use bioretention cells as rain gardens in landscaped parking lot islands to
reduce runoff volume and filter pollutants.
Disconnect the downspouts from roofs and direct the flow to permeable paver areas
or other vegetated infiltration / filtration practices.
Use multi-functional open drainage systems in lieu of more conventional
Use green roofs for runoff reduction, energy savings, improved air quality, and
Apply a treatment train approach to provide multiple opportunities for stormwater
treatment and reduce the possibility of system failure. The example
in sketch D above combines a grassed swale with permeable paver overflow areas and a
landscaped bioretention cell.
