How can you enhance stormwater filtration in a landscape?

The enhancement of stormwater filtration in a landscape is effectively achieved by incorporating bioswales and rain gardens with native plants. This approach is beneficial because bioswales and rain gardens are designed to capture and filter stormwater runoff. They do this through a combination of vegetation, soil, and organic matter that help promote infiltration and remove pollutants from the water before it enters the stormwater system or nearby water bodies.

Native plants are particularly effective in this context, as they are adapted to the local climate and soil conditions, requiring less maintenance and water compared to non-native species. Their deep root systems also help to improve soil structure and water absorption. Moreover, these plants can provide habitat for wildlife, contributing to biodiversity.

In contrast, using synthetic materials for ground cover can create impermeable surfaces that lead to increased runoff and pollution, while concrete drainage systems can exacerbate this issue by directing water away without allowing for natural filtration. Avoiding soil amendments does not support healthy soil and vegetation, which are crucial for effective stormwater management. Through the integration of natural systems, the landscape not only becomes more effective at managing stormwater but also enhances ecological benefits.
