This article is about definitions. The regional context for LID is presented in [[Urbanization]] and [[Climate change]].  

This guide has been developed 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 [https://www.epa.gov/nps/urban-runoff-low-impact-development United States Environmental Protection Agency] will be used:

GI describes a strategically planned and delivered network of natural and semi-natural elements that collectively deliver a wide range of ecosystem, social and economic services to help reduce dependence on grey infrastructure and to address environmental resilience and climate change.

GI describes a strategically planned and delivered network of natural and semi-natural elements that collectively deliver a wide range of ecosystem, social and economic services to help reduce dependence on grey infrastructure and to address environmental resilience and climate change.

The LID approach to stormwater management falls under the overarching umbrella of GI as a semi-natural element.

LID comprises comprehensive, engineered site-design strategies and techniques that seek to mitigate the impacts of increased runoff and stormwater pollution by replicating or maintaining the site’s pre-development hydrological and ecological functions. This is achieved as close to the runoff source as possible through the processes of retention, filtration, infiltration and evapotranspiration. These practices can effectively remove [[nutrients]], pathogens and [[metals]] from runoff, and they reduce the volume and intensity of stormwater flows.
