Low Impact Development - they say “green is the new grey” but what does this mean?

Bert van Duin

This presentation provides an overview of the evolution of stormwater management, and discusses how green “low impact development” practices such as absorbent landscaping, rain gardens, bioretention filters or green roofs can take over from conventional grey drainage infrastructure.

It also provides links to the open space planning process from overarching watershed visions, down to community master drainage planning including development setbacks and bylaws, and down to site implementation. Specific attention is paid to the interaction between stormwater and landscape design professionals with respect to responsibilities, operation and maintenance requirements, and enforcement.
