Low impact development

Low Impact Development (LID) is a sustainable land planning and engineering design approach that manages stormwater runoff as close to its source as possible. Rather than relying on traditional infrastructure like storm drains and pipes, LID uses natural processes to reduce runoff volume, improve water quality, and maintain the natural hydrology of a site. Techniques include green roofs, rain gardens, permeable pavements, bioswales, and vegetated buffers. These systems slow, filter, and absorb rainwater, reducing the risk of flooding, erosion, and water pollution in urban and suburban areas.

LID is widely recognized for its environmental, economic, and aesthetic benefits. It helps recharge groundwater, reduce heat island effects, and enhance urban green space—all while often being more cost-effective than conventional stormwater systems. Municipalities and developers are increasingly incorporating LID into planning regulations and building codes to support climate resilience and sustainable development. By integrating LID into project designs early on, communities can create healthier ecosystems, improve quality of life, and support biodiversity in urban environments. Low Impact Development transforms stormwater from a waste product into a valuable resource. It offers a practical, nature-based solution to modern urban water management challenges. As cities grow, LID will be essential for creating resilient, water-smart communities.
