Which of the following strategies contributes to earning credits in sustainable site development?

Promoting water-efficient landscapes is a valuable strategy for earning credits in sustainable site development because it directly contributes to minimizing water usage, enhancing the quality of the local environment, and supporting biodiversity. Sustainable site development focuses on managing a site in a way that minimizes the impact on ecosystems and promotes resource conservation.

Water-efficient landscapes often incorporate native plant species, drought-resistant vegetation, and efficient irrigation systems, which collectively reduce the overall demand for water. This approach not only lessens the strain on municipal water supply systems but also helps to maintain local water tables and ecosystems. Additionally, utilizing such landscapes can provide habitats for local wildlife and contribute to the aesthetic value of the site.

In contrast, increasing parking spaces, expanding the building's footprint, and using traditional landscaping techniques generally do not align with sustainable practices. These approaches can lead to greater impervious surface area, increased water runoff, and higher resource consumption, which are contrary to the goals of sustainable site development.
