​Retrofitting Existing Development

Low Impact Development (LID) practices can be applied to new development, redevelopment, or as retrofits to existing development. LID has been adapted to a range of land uses from high density ultra-urban settings to low density development.

Ideal sites for LID retrofit projects include:

  • Road Right-of-Ways
  • Industrial and Commercial Lands
  • Residential Lands
  • Public Lands (municipal facilities, parks, schools, places of worship)

George Richardson Stormwater Management Pond Retrofit (Newmarket) Constructed: 2010-2012
 

Implementing sustainable low impact development practices on existing development helps to enhance how stormwater is managed in older areas built before modern stormwater controls. LID can support sustainability targets, address flood mitigation, improve communities and show commitment to the local environment.

Industry partners have developed a series of LID case studies from sites across Ontario that have already implemented LID projects so that you can learn from the barriers, issues and challenges they encountered and how they were overcome.
