What is an eco-friendly practice that can be included in a SWPPP?

• A. Utilizing artificial turf
• B. Implementing rain gardens
• C. Planting non-native species
• D. Regular pavement sealing

Answer: (B)

Implementing rain gardens is an eco-friendly practice that enhances stormwater management in a Stormwater Pollution Prevention Plan (SWPPP). Rain gardens are designed to collect and absorb rainwater runoff from impervious surfaces like roofs and driveways. By incorporating native plants and soils that facilitate water absorption, these gardens help to reduce flooding, minimize erosion, and filter pollutants from stormwater before it reaches natural water bodies.

Rain gardens also contribute to biodiversity by providing habitat for various species, promoting a healthier ecosystem. Additionally, they can improve aesthetic value in the community and improve local air quality by enhancing green spaces. Overall, utilizing rain gardens effectively addresses both stormwater management and environmental conservation, making them a valuable addition to a SWPPP.

In contrast, options such as utilizing artificial turf or planting non-native species do not support local ecosystems effectively, while regular pavement sealing can cause increased runoff by maintaining hard surfaces that do not absorb rainwater.
