Low Impact Development
Low Impact Development (LID) is a comprehensive approach to land use planning and design that aims to mitigate the impacts of land use on the environment. One of LID's main objectives is to reduce the runoff and pollutants that end up in streams and larger water sources by mimicking the pre-development conditions of an area.
Urbanization presents an issue for water sources as it leads to the creation of impenetrable surfaces, leading to more runoff into streams and storm drains than would occur if the land was left untouched. This reduces the filtration of water and increases flooding risks.
The solution presented by Low Impact Development is to utilize tools such as rain barrels, green roofs, porous pavement surfaces, and the planting of native species to increase the amount of precipitation that can be absorbed into the ground, increasing filtration of pollutants and reducing the chances of a flood. LID presents an opportunity to actively protect our watershed for present and future generations while simultaneously protecting our investments – in a monetary and a timely manner.
