LEED-AP-BD+C Exam Dumps : LEED AP Building Design + Construction (LEED AP BD+C)

Green Infrastructure (GI) and Low-Impact Development (LID) rainwater management strategies improve upon the conventional approach for rainwater management by replicating a site’s natural hydrology. GI and LID are design approaches that use various practices to mimic the natural water cycle and reduce the negative impacts of development on the environment. They aim to preserve, restore, or create natural features that can capture, infiltrate, evaporate, or reuse rainwater on site, rather than conveying it to a centralized stormwater system. By doing so, they can reduce runoff volume and peak flow, improve water quality, enhance groundwater recharge, increase biodiversity, and create more attractive and resilient landscapes. Therefore, option A is the correct answer. The other options are not true for GI and LID strategies. Discharging rainwater at a faster rate (option B) would increase the risk of flooding, erosion, and pollution downstream. Increasing a site’s impervious surface (option C) would reduce the infiltration and evaporation of rainwater and increase runoff and heat island effects. Providing a greater volume of rainwater detention (option D) would not necessarily improve the site’s hydrology, as detention is only a temporary storage of rainwater that does not address the runoff quality or quantity issues. For more information on GI and LID rainwater management strategies, you can refer to the LEED v4 Reference Guide for Building Design and Construction1 or the Green CE course on Rainwater Management for LEED v4.1 Projects2.

Detailed Explanation:

To achieve three points under the Rainwater Management credit, projects must manage the 95th percentile of regional rainfall events on site. This approach minimizes the impact of stormwater runoff on local watersheds and supports the use of low-impact development (LID) techniques such as bioswales, green roofs, and rain gardens.

LEED BD+C Location and Transportation (LT) Credit: High Priority Site encourages development in locations with existing infrastructure to promote sustainable land use.

Option 1: Historic District applies to projects located in designated historic districts where at least 75% of land within ½ mile (0.80 km) is previously developed.

Brownfields (Option C) and Federal Renewal Communities (Option D) are separate site categories that fall under different High Priority Site options.

The ¾ mile (1.20 km) radius in Option A is incorrect, as LEED specifically sets the requirement at ½ mile (0.80 km).

To earn this credit under Option 1, a project in a historic district must demonstrate that the surrounding land is predominantly redeveloped.
