Engineering Vegetated Roofing Systems to Optimize Stormwater Management – LA/CES APPROVED
Karen Liu, PhD, Green Roof Specialist & Sasha Aguilera, GRP, B.Arch, Design Ambassador
Urban centers have high concentrations of impervious areas which pose a challenge in managing large volumes of stormwater. Heavy rain events or back-to-back storms cause problems like flooding, property damage, and combined overflow sewer discharge. Green infrastructure, such as vegetated roofs, can help mitigate these problems because they restore the hydrologic cycle in urbanized areas. Vegetated roof systems designed for maximum stormwater management decrease the volume of stormwater within the urban core and reliably delay travel time of stormwater to the treatment plant. These retention and detention strategies help alleviate the burden of heavy stormwater on our cities’ infrastructure.
