What is Low Impact Development?

Low impact development (LID) uses a variety of practical techniques to manage stormwater runoff close to its source, where rain falls.  LID designs focus on implementing better site design practices and site specific stormwater control options such as green roofs, stormwater capture and re-use, and landscape designs that increase the absorption and filtering of rainwater.

What are the Benefits?

LID is an ecosystem-based approach where water is the central focus. Albertans need spaces to work, live and play. Applying LID principles, the built environment can be designed to be a sustainable functioning part of an ecosystem. LID is not a land use control strategy. Innovative planning and engineering models help predict the impacts of stormwater before and after development occurs. This information enables better decision making towards where LID designs can be applied to reduce the impacts of development on the natural landscape. LID designs work for new developments and brownfield sites as well as for retrofitting existing communities with
stormwater challenges.

Using LID, planners and engineers can promote the recharging of aquifers, protection of riparian areas and wetlands, as well as, maintain the aquatic health of streams and rivers. These actions improve the aesthetics of development and enhance the quality of life residents enjoy and seek in their communities.
