Applicability  

The goal of LID is to retain the hydrologic characteristics of each site, improve stormwater quality, maintain downstream stability, and reduce the need for conventional stormwater management and conveyance systems. Low Impact Development is a concept that utilizes integrated management practices (IMPs). These IMPs are a flexible set of strategies that can be applied to any development project, regardless of scale. Generally, however, these strategies are best applied to newly developed sites. Existing developments must be retrofitted and may be more expensive.
