The primary goal when reducing impervious hardscapes on a site is indeed to enhance water absorption and reduce runoff. Impervious surfaces, such as concrete or asphalt, prevent water from being absorbed into the ground, leading to increased surface runoff, which can contribute to flooding, erosion, and water quality issues. By decreasing the amount of these surfaces, a site can allow more water to infiltrate the soil, promoting groundwater recharge and improving overall site hydrology.

Moreover, reducing impervious areas can create space for green infrastructure, such as rain gardens, permeable pavements, and vegetated swales, which can further manage stormwater effectively. This approach not only helps with ecological balance but also contributes to a more sustainable urban environment.

Options focused on expanding the building footprint, adding more parking spaces, and limiting plant diversity do not align with sustainable practices aimed at enhancing environmental quality or managing stormwater. Instead, these choices may lead to negative impacts on site hydrology and biodiversity.
