Usable SuDS Features.
Innovative Engineering Approaches.
At the heart of the design are a range
multi-functional SuDS features including
planted basins, raingardens and rainsculptures. The majority of resurfacing
was completed with permeable paving,
which captures the rainfall and directs
it immediately below the surface of
the pavement to two planted basins.
Significant onsite constraints were
present such as high voltage power
cables and concrete slabs that formed the
substructure of the existing roadway.
McCloy Consulting, the project Engineers,
adopted an innovate approach for the
permeable pavement design to reduce
costs and minimise requirements to dig
out existing concrete with permeable
pavement being formed directly onto
the slab no more than 200mm deep. This
enabled the main basins to be designed by
Robert Bray Associated as shallow features
that sit comfortably within the landscape.
The flow controls restrict flows to below
1 litre per second. This is a different

approach to that which would normally
be applied and it provides greater
benefit to the receiving sewer, reducing
CSO spills, risk of urban flooding and
significantly exceeding normal compliance
requirements without any additional cost
to the client.
Success.
This innovative project was completed
in September 2015 and showcases an
exemplar of how SuDS can be successfully
integrated as part of the landscape of our
towns and cities.
