The Low Impact Development Stormwater Management Planning and Design Guide (LID SWM Guide) is being developed by Credit Valley Conservation (CVC), Grand River Conservation Authority (GRCA), Lake Simcoe Region Conservation Authority (LSRCA), and Toronto and Region Conservation Authority (TRCA) as a tool to help developers, consultants, municipalities and landowners understand and implement more sustainable stormwater management planning and design practices in their watersheds. Many jurisdictions have defined the term low impact development. For this document, the following definition, adapted from the United States Environmental Protection Agency (U.S. EPA, 2007) will be used:

'''Welcome user! We have been looking forward to your arrival.'''
In anticipation we have prepared a short printable form to help direct your critique of the wiki.
{{textbox|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.}}
