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:

The field of stormwater management has undergone considerable evolution in the last 40-50 years, from underground drainage systems for rapid water disposal, to stormwater management ponds, to today’s myriad of near-to-nature practices and technologies<ref name ="Fletcher" />. This paradigm shift could be explained by a change of perception about water from a waste to a resource. With this evolution comes the evolution of terminology to describe the latest visions, practices and technologies.

There are various terms used in stormwater management related literature across the globe. Some terms differ only in their geography while others differ in their connotation.
