In class: Advanced LID Design: Bioretention Facilities Workshop

Monday, October 21, 2019

8:30 a.m. to 4:30 pm.

Grand River CA Head Office - Auditorium , Cambridge (View Map)

$100 CAD

Green infrastructure, including low impact development (LID) practices, is becoming an increasingly common approach to stormwater management control. Bioretention is one type of LID measure that is designed to treat runoff from paved areas by using the natural properties of soil and vegetation to remove contaminants. Water management practitioners need to be familiar with the ‘ins and outs’ of bioretention design including sizing and siting, inlet and outlet design, material specification, construction planning, as well as the associated lifecycle inspection and maintenance requirements that should be considered during the design process.

Using an example project site, participants will be guided through a bioretention design problem including:

  • Bioretention basics and terminology
  • Review of performance studies
  • Screening design options
  • Sizing for hydrologic and water quality objectives
  • Site planning and placement of bioretention areas
  • Site grading and drainage
  • Planting design
  • Material specifications
  • Detailed design options for inlets/pretreatment
  • Detailed design options for outlets/flow control
  • Construction planning and sequencing, with erosion and sediment control
  • Maintenance planning
  • Design documentation
  • Certification/Assumption protocols

Who should attend:
A course intended for stormwater engineers, planners, landscape architects, agency and municipal staff.
