Reinventing Rainwater Management and Governance in Canada—New Resource to Help Communities Achieve Water Sustainability

The POLIS Project on Ecological Governance in partnership with the University of Victoria’s Environmental Law Centre recently released the latest instalment in its water sustainability handbook series for decision makers, policy analysts, community leaders, and water managers. Peeling Back the Pavement: A Blueprint for Reinventing Rainwater Management in Canada’s Communities by Susanne Porter-Bopp, Oliver M. Brandes, and Calvin Sandborn outlines the problems with conventional stormwater management and examines solutions for moving toward sustainability.

Thermal Impacts of Urbanization Including Preventative and Mitigation Techniques

Low Impact Development Stormwater Management Planning and Design Guide

Permeable paver parking lot, CVC Main Office, Mississauga, ON

The Low Impact Development (LID) Stormwater Management Guide is a joint initiative of the Toronto and Region and Credit Valley Conservation Authorities that has been developed in consultation with representatives from the Ministry of the Environment, Fisheries and Oceans Canada, GTA municipalities and the development industry.

Both TRCA and CVC have been involved in integrated watershed-wide environmental monitoring and modelling activities for several years, and the results of this work have revealed that the environmental health of many watersheds continues to decline with increased urbanization. This deterioration has occured despite widespread adoption of the conventional stormwater management planning and design practices described in provincial and conservation authority policy documents. Documents such as the CVC's Credit River Water Management Strategy Update and the TRCA's Watershed Plans for the Rouge (2007), Humber (2008) and Don (2009) Rivers have concluded that a shift away from conventional approaches and towards low impact development is essential to protecting watershed health, and improving watershed resiliency to some of the hydrologic impacts of climate change. 

The guide was developed to provide engineers, ecologists and planners with up-to-date information and direction on landscape-based stormwater management planning and low impact development stormwater management practices, and thereby help ensure the continued health of the streams, rivers, lakes, fisheries and terrestrial habitats in the CVC and TRCA watersheds.   It is also intended to help streamline and focus the design and review process, as well as ensure that the goals, objectives and targets outlined in watershed and subwatershed studies are being met.
