In stormwater management strategies, what is typically increased to improve water quality?

• A. Runoff coefficients
• B. Vegetative cover
• C. Impervious surfaces
• D. Drainage capacity

Answer: (B)

Increasing vegetative cover in stormwater management strategies plays a crucial role in improving water quality. Vegetation, such as grass, trees, and shrubs, helps to filter pollutants from stormwater runoff before it reaches water bodies. Plants absorb nutrients, trap sediments, and facilitate the infiltration of water into the soil, which reduces erosion and minimizes the volume of runoff. Additionally, vegetative cover promotes biological activity in the soil, which can further break down contaminants. This natural filtration process is essential in urban areas where impervious surfaces are prevalent, as these surfaces prevent rainwater from soaking into the ground and increase the speed and volume of runoff, carrying more pollutants into waterways. The emphasis on increasing vegetative cover is a critical aspect of sustainable stormwater management, as it aligns with environmentally beneficial practices that seek to mimic natural hydrological processes. By fostering a healthier landscape through vegetation, communities can enhance water quality and preserve aquatic ecosystems.
