A. waste area
B. sensitive area
C. pervious area
D. impervious area
Answer
D. impervious area
Explanation
Strategically locating functional and decorative hardscape on a project site can reduce the amount of on-site impervious area. Impervious surfaces are surfaces that do not allow water to infiltrate into the ground (e.g., concrete or asphalt). By reducing these surfaces, we can increase water infiltration, which helps recharge groundwater supplies and reduces stormwater runoff that can lead to erosion and water pollution.
Strategically locating hardscape elements, such as walkways, patios, and decorative features, can help reduce the amount of impervious area on a project site. Impervious surfaces, like concrete and asphalt, prevent water from infiltrating into the ground, leading to increased runoff and potential environmental issues.
By carefully planning the placement of hardscape, project teams can:
- Minimize the total area of impervious surfaces
- Concentrate hardscape in areas where it is most needed for functionality and accessibility
- Preserve more of the site’s natural pervious surfaces, such as soil and vegetation
Pervious surfaces allow water to percolate into the ground, reducing runoff and supporting the natural water cycle. Maintaining a higher proportion of pervious area on a site helps to:
- Recharge groundwater
- Filter pollutants
- Mitigate the urban heat island effect
- Support local ecosystems
In the context of LEED (Leadership in Energy and Environmental Design), managing impervious surfaces is a key consideration for sustainable site development. By strategically placing hardscape and maximizing pervious area, projects can earn points toward LEED certification while promoting environmental stewardship.
