Line 292: The LID SWM Guide provides information and direction to assist engineers, ecologistsand planners with landscape-based stormwater management planning and theselection, design, construction and monitoring of sustainable stormwater managementpractices. The focus of this guide is on guidance regarding the planning and design ofstructural low impact development practices for stormwater management.The practice of managing stormwater is continuing to evolve as the science ofwatershed management and understanding of our watersheds grow. Effectivemanagement of stormwater is critical to the continued health of our streams, rivers,lakes, fisheries and terrestrial habitats. CVC and TRCA believe that an improvedunderstanding of the municipal and environmental planning process and therequirements for stormwater management will lead to improvements in managementpractices and an increasingly standardized and streamlined approach to addressingstormwater throughout the CVC and TRCA watersheds.The LID SWM Guide is intended to augment the Ontario Ministry of the Environment(OMOE) Stormwater Management Planning and Design Manual (2003). The OMOEmanual provides design criteria for “conventional” end-of-pipe stormwater managementpractices such as wet ponds and constructed wetlands but provides only limitedinformation 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-ofpipestormwater management practices – is usually required to meet the multipleobjectives 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 stormwatermanagement practices that have been used extensively in Europe, the United States,British Columbia and at demonstration sites in Ontario. These practices have onlyrecently been considered for broad application in Ontario as part of the treatment trainapproach. 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 supportsthe use of the treatment train approach for stormwater management. Accordingly, thereader is urged to refer to the OMOE manual (OMOE, 2003), as a guide forincorporating more traditional practices such as wet ponds and wetlands into the overallstormwater management planning and design process.The LID SWM Guide is not intended to limit innovation or restrict the use of creativesolutions for stormwater management. Indeed, the OMOE, CVC, TRCA and partnermunicipalities encourage the development of innovative designs and technologies.= Related Documents =This manual is not a stand-alone document. It is intended to augment the OntarioMinistry of the Environment’s 2003 Stormwater Management Planning and DesignManual, which provides design criteria for “conventional” end-of-pipe stormwatermanagement practices such as wet ponds and constructed wetlands. It is also acompanion document to other stormwater related guidance documents prepared byCVC and TRCA.
