Site Conditions[edit]

Define Design Criteria[edit]

A detailed description of the design criteria that need to be defined is provided in the

respective CVC and TRCA Stormwater Management Criteria documents. If outside jurisdictional

boundaries, criteria developed should have requirements to:


  • preserve groundwater and baseflow characteristics;
  • prevent undesirable and costly geomorphic changes in the watercourse;
  • prevent any increases in flood risk potential;
  • protect water quality; and ultimately,
  • maintain an appropriate diversity of aquatic life and opportunities for human uses


The design criteria required to protect, enhance or restore the environmental resources

can be grouped under the following five categories.

  • Flood Protection;
  • Water Quality;
  • Erosion Control;
  • Recharge; and
  • Natural Heritage Systems or green infrastructure

Screen Potential LID Options[edit]

A number of factors need to be considered when screening the suitability of a given

location within a development site for application of stormwater BMPs. Table 3.4.1

summarizes site constraints associated with some general types of structural LID

practices for stormwater management that should be considered. Further

information regarding constraints to the design of various end-of-pipe BMPs can be

found in the Ontario Ministry of the Environment Stormwater Management Planning and

Design Manual (2003). The use of LID BMPs should be considered first to meet the

design criteria before the use of end-of-pipe BMPs.
