Low Impact Development (LID)
Low Impact Development (LID) is a set of design strategies and practices that aim to manage stormwater runoff and reduce its impact on the environment. Instead of relying on traditional "gray" infrastructure like pipes and concrete channels, LID promotes the use of "green" infrastructure like rain gardens, bioswales, permeable pavements, and green roofs to mimic natural hydrological processes and improve water quality.
LID aims to reduce the amount of stormwater runoff that leaves a site by promoting infiltration, evapotranspiration, and storage. By doing so, LID can help prevent erosion, flooding, and water pollution, promoting groundwater recharge and enhancing a site's aesthetic and ecological value.
LID can be implemented in a variety of settings, from urban to rural, and can be applied to both new and existing developments. LID practices can also provide multiple benefits beyond stormwater management, such as enhancing wildlife habitat, improving air quality, and reducing the urban heat island effect.
Overall, LID is a sustainable approach to managing stormwater that recognizes the value of natural systems and works to integrate them into the built environment.
