Lessons in LID Construction

Low Impact Development (LID), an innovative stormwater management approach that treats, infiltrates, filters, and retains runoff at the source, is quickly becoming the new norm in Ontario. Construction of LID practices involves techniques and specifications that differ from traditional stormwater management construction practices. Failing to follow proper LID construction methods can result in barren bioretention landscapes, clogged infiltration practices, uneven permeable pavements, and ultimately costly post-construction repairs. This course is applicable to anyone involved in the design, construction, and inspection of LID, whether it is in a large subdivision development or a small parking lot retrofit. Instructors will take participants through each step of the LID construction highlighting potential errors and explaining proper techniques. Participants will also receive recommendations for specifications and tender contracts. The experienced instructors will present valuable lessons learned from examples in Ontario and similar cold climate regions.

Learning Objectives:

  1. Identify how LID construction differs from the construction of a conventional stormwater management site. 
  2. Know the common methods for constructing LID practices and specifying thier materials.
  3. Beware of common construction pitfalls and how to avoid them.
