Low Impact Development – Retrofits

These guides provide step-by-step guidance on how to retrofit existing properties to incorporate LID stormwater management technologies. Guides are tailored to specific land-uses, including road right-of-ways, private lands, public lands, residential lands and an overarching guide to assist municipalities on how to implement city-wide retrofit programs.

Nevertheless, concerns have been expressed about the potential for contaminating groundwater resources due to intentional infiltration of pollutant-containing stormwater (Pitt et al. 1999; Weiss et al. 2008).
