| − | {{TextBox|1=Low impact development (LID) is a stormwater management strategy that seeks to mitigate the impacts of increased runoff and stormwater pollution by managing runoff as close to its source as possible. LID comprises a set of site design strategies that minimize runoff and distributed, small scale structural practices that mimic natural or predevelopment hydrology through the processes of infiltration, evapotranspiration, harvesting, filtration and detention of stormwater. These practices can effectively remove nutrients, pathogens and metals from runoff, and they reduce the volume and intensity of stormwater flows.}} | + | {{Clickable button|[[Table of Contents]]}} |

| − | The practice of managing stormwater is continuing to evolve as the science of
| |
| − | watershed management and understanding of our watersheds grow. Effective
| |
| − | management of stormwater is critical to the continued health of our streams, rivers,
| |
| − | lakes, fisheries and terrestrial habitats. CVC and TRCA believe that an improved
| |
| − | understanding of the municipal and environmental planning process and the
| |
| − | requirements for stormwater management will lead to improvements in management
| |
| − | practices and an increasingly standardized and streamlined approach to addressing
| |
| − | stormwater throughout the CVC and TRCA watersheds.

| − | (OMOE) Stormwater Management Planning and Design Manual (2003). The OMOE
| + | |} |
| − | manual provides design criteria for “conventional” end-of-pipe stormwater management
| |
| − | practices such as wet ponds and constructed wetlands but provides only limited
| |
| − | information about lot level and conveyance controls. The OMOE manual does, however,
| |
| − | emphasize the use of a “treatment train” approach to reduce the impacts of stormwater runoff. A treatment train approach – a combination of lot level, conveyance, and end-ofpipe
| |
| − | stormwater management practices – is usually required to meet the multiple
| |
| − | objectives of stormwater management, which include maintaining the hydrologic cycle,
| |
| − | protecting water quality, and preventing increased erosion and flooding.
| |
| − | | |
| − | This LID SWM Guide focuses on a number of lot level and conveyance stormwater
| |
| − | management practices that have been used extensively in Europe, the United States,
| |
| − | British Columbia and at demonstration sites in Ontario. These practices have only
| |
| − | recently been considered for broad application in Ontario as part of the treatment train
| |
| − | approach. These low impact development practices include green roofs, bioretention,
| |
| − | permeable pavement, soakaways, perforated pipe systems, enhanced grass swales,
| |
| − | dry swales and rainwater harvesting. The LID SWM Guide recommends and supports
| |
| − | the use of the treatment train approach for stormwater management. Accordingly, the
| |
| − | reader is urged to refer to the OMOE manual (OMOE, 2003), as a guide for
| |
| − | incorporating more traditional practices such as wet ponds and wetlands into the overall
| |
| − | stormwater management planning and design process.
| |
| − | | |
| − | The LID SWM Guide is not intended to limit innovation or restrict the use of creative
| |
| − | solutions for stormwater management. Indeed, the OMOE, CVC, TRCA and partner
| |
| − | municipalities encourage the development of innovative designs and technologies.
