According to the guidelines for reuse of land, how much of the land must have been previously developed?

The correct answer is based on the requirements outlined in the Estidama Pearl Building Rating System (PBRS), which emphasizes sustainable development and the efficient use of resources. The guidelines for reuse of land state that to qualify for certain credits, at least 75% of the land must have been previously developed. This minimum threshold encourages the revitalization of existing urban areas rather than the expansion into undeveloped land.

By focusing on previously developed land, the guidelines aim to reduce urban sprawl, minimize the environmental impact of new developments, and utilize existing infrastructure more effectively. This approach not only promotes sustainability but also helps maintain ecological balance by preserving green space and natural habitats that might be lost if undeveloped land were to be used for new projects.

Other options, such as 50%, 100%, or 25%, do not meet the established criteria. For instance, a requirement of less than 75% might not sufficiently encourage the efficient use of existing developed areas, while 100% could limit potential development sites too severely, hindering overall urban redevelopment initiatives. Therefore, choosing 75% aligns with the overarching goals of the PBRS to promote sustainable land use practices.
