Credit Valley Conservation Stormwater Management Criteria, August 2012

A significant development from the Ministry of Environment and Climate Change regarding Low Impact Development (LID) stormwater management practices.

The Ministry of the Environment and Climate Change has issued the following interpretation bulletin after ongoing discussions with other Provincial ministries, conservation authorities and others. It addresses the limitations of existing stormwater management practices and endorses LID for new development and retrofits, as a way to more closely mimic natural hydrology.

This document was prepared by the Credit Valley Conservation Authority (CVC), in partnership with the Toronto and Region Conservation Authority (TRCA) and our watershed stakeholders. This NEW Stormwater Management Design Criteria provides guidance in the planning and design of stormwater management infrastructure for developers, consultants, municipalities, and landowners, and outlines the processes and infrastructure needed to address flooding, water quality, erosion and water balance.

The NEW CVC Stormwater Management Criteria was reviewed by SWM Criteria Document Working Group of Building Industry and Land Development Association (BILD) and a Letter of Support was issued by BILD Halton and Peel chapter members.

The CVC Board conducted a final review of the document and approved the document on September 14, 2012.
