Low Impact Development (LID) Case Studies

Low Impact Development (LID) is an innovative technology to control stormwater quantity / quality impacts at the source using micro-scale management practices distributed and integrated throughout the landscape. This technology, developed by Prince George's County, Maryland, to address perceived problems in conventional approaches to stormwater management (SWM) within the County and the State, makes multifunctional use of the urban landscape allowing one to design a hydrologically functional site. This approach results in an ecologically based approach to stormwater management that is usually more aesthetically pleasing, precludes impacts to receiving waters, and is generally less costly to construct and maintain than conventional end of pipe systems This poster session provides a chronological overview of a number of projects which have been instrumental in the development of LID technology. The focus of the paper is on case studies and demonstration projects. While the emphasis of these projects is the state of Maryland, projects and case studies from other regions of the Country are also included.
