As part of an initiative to resolve stormwater flooding issues at London Underground depots, Transport for London installed two green roofs on a London Underground depot at West Ruislip. One roof used industry-standard green roof construction materials, the other used a novel experimental system.
The SRI was contracted to monitor the rainfall runoff from these green roofs and an adjacent control roof. Data from the monitoring was used to inform best practice for green roof design for water attenuation as supporting evidence for a broader incorporation of green infrastructure retrofit across Transport for London holdings.
