New document confirms Ministry of Environment and Climate Change expectations for stormwater management
After months of rumours and delay, it’s finally here: the new interpretation bulletin from the Ministry of Environment and Climate Change outliningExpectations re: stormwater management.
The language will be familiar to members of the Umbrella community. The bulletin discusses the effects of urbanization and climate change on water quality and quantity, the importance of managing rain close to where it falls, mimicking the natural hydrological cycle, and the need for cities to adapt to climate change.
The interpretation bulletin is “intended to encourage stormwater management applications that emphasize low impact development techniques while the ministry undertakes the development of a low impact development stormwater management guidance document, targeted for completion in 2016.â€
It notes that the 2003 Stormwater Management Planning and Design Manual already spells out a treatment train approach to stormwater management. That document states that “lot level and conveyance controls, specifically infiltration-based controls, are required to maintain the natural hydrologic cycle to the greatest extent possible.â€
