Designing Bioretention Facilities

Jim Newton, P.E., DEE

Bioretention is an upland based water quality and water quantity control practice that uses chemical, biological and physical processes to remove pollutants from stormwater. Bioretention may also mimic predevelopment hydrology. Bioretention is considered a low impact development (LID) process. The designer of a bioretention facility should consider:

  • Site conditions and constraints
  • Proposed land uses
  • Plant types
  • Soil types
  • Stormwater pollutants
  • Soil moisture conditions
  • Proper drainage
  • Groundwater recharge and
  • Overflows

  • This course expands on two current PDH Online courses titled “Introduction to Bioretention”, C193 and “Design of Bioretention Systems”, C194 and covers key environmental aspects of bioretention systems including landscaping considerations, construction aspects and selling environmental aspects of the systems.

    The text for this course is Chapters 3-5 of the award winning “Prince George’s County Bioretention Manual, revised December 2002”.

    This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
