What is Low Impact Development (LID)?
What are Examples of LID? Green Roofs Green roofs have a vegetative layer of grass, ground cover, or even trees. They absorb rainfall, extend a roof's life, and reduce energy costs. Native Landscaping Landscaping with plants that are native to your area means less fertilizer, watering, and care. Native plants have longer roots that absorb more storm water and pollutants than turf grass. Rain Garden Rain gardens have a dip at the center to collect, filter, and soak up rainwater. They are planted with native shrubs, wildflowers, and grasses, which need less fertilizer and water than non-native plants. Grass Swale Grass swales have a broad, gently sloped channel and thick vegetation. These swales collect and absorb storm water and pollutants. Porous Pavement Porous pavement has spaces that let rainwater pass through. Because water can soak Storm Water Reuse Storm water reuse is the recycling of rainwater. Storm water is stored for irrigation or other uses. Through its collection and reuse, storm water does not have to be dumped into the storm sewer.

LID is a better way to manage storm water. LID techniques store, filter, and absorb storm water where it falls to mimic natural site conditions. LID keeps large volumes of storm water, and associated pollutants, from reaching our waterbodies.
into the soil, this type of pavement does not create large volumes of storm water runoff.
