New developments must put SuDS at the forefront of schemes if they want planning approved
Thankfully, sustainable drainage features heavily within the Redbridge London Plan (2015-2030), so the council were only too happy to see nature-based sustainable drainage systems (SuDS) incorporated into the
proposal. The planning officer has experienced the impact of surface run-off first-hand
but also recognised the benefits of improved water quality and enhanced
The Raven Road scheme includes an intensive green roof, with a deep substrate (230mm) which allows for the growth of a variety of nectar rich perennials and tall grasses providing year round interest but also allowing a greater volume of water to be attenuated.
The top roofs are described as extensive green roofs (100-150mm substrate) which means they can be seeded with native species and
offer a precious undisturbed habitat for invertebrates and the rare black
redstart whilst also contributing to the stormwater attenuation.
The use of street trees in the scheme sees the tree canopy rise by more than 10%, and again, by using SuDS tree pits, stormwater is filtered and attenuated. The green wall faces the wall of the offices and provides further habitat and will develop into a complex vertical structure.
This new scheme on Raven Road , coupled with Crossrail’s arrival, secures Redbridge’s future as an attractive, well-connected part of London. To read more about Raven Road click here.
