What is one benefit of using low-impact development (LID) techniques?

Using low-impact development (LID) techniques is beneficial primarily because they minimize impervious surfaces and promote natural filtration and infiltration. This approach is vital for managing stormwater effectively. By reducing impervious surfaces, LID allows rainwater to soak into the ground rather than running off into storm drains, which helps recharge groundwater supplies and maintain the natural hydrology of the area.

Furthermore, the promotion of natural filtration means that the water that does run off is filtered through vegetation and soil, which can help remove pollutants and improve water quality before it reaches waterways. This aligns with sustainable practices aimed at protecting the environment and managing water effectively in urban settings.

The other choices reference aspects that do not accurately represent the core benefits of LID. For instance, while reducing harmful chemicals is a worthy goal in environmental management, it is not a primary function of LID. Similarly, while LID can lessen the need for extensive stormwater management plans due to its inherently preventive nature, it does not eliminate the need for such plans altogether. Lastly, the concept of providing immediate drainage does not address the overarching principles of LID, which focus on managing stormwater through infiltration and natural processes rather than simply removing it quickly.
