What are LID BMPs and what value do they have for my watershed?
A Low Impact Development (LID) best management practice (BMP) is a stormwater management strategy concerned with maintaining or restoring the natural hydrologic functions of a site to achieve natural resource protection objectives and fulfill environmental regulatory requirements. LID BMPs employ a variety of natural and built features that reduce the rate of runoff, filter out its pollutants, and facilitate the infiltration of water into the ground. LID BMPs help to improve the overall quality of receiving surface waters and stabilize the flow rates of nearby streams. The watershed values include the preservation/protection of environmentally sensitive site features such as riparian buffers, wetlands, steep slopes, valuable (mature) trees, flood plains, woodlands, and highly permeable soils.
