SuDS in London - a guide

Kings Cross LWT: Camley Street
A soil scientist is part of the SuDS team
private developer’s team, working with
the Highways, Planning and Lead Local
Flood Authorities.
The Surface Water Management (SWM)
objectives should be set and
underpinned by:
• SuDS design principles
• Townscape and landscape character
• Local planning policy
• Functional demands of the street
• Evaluation of any existing SuDS features
• A long-term outlook
The planning and drainage design process
should include:
• Agreeing with the planning authority the
level of detail required and any aspects
that require a planning condition
• Identifying a way to ensure the designs
are delivered according to specification
• Community and stakeholder engagement
To start, the design process should
consider the various site-specific
constraints, as these will be one of the
biggest design drivers. Baseline data will
be vital, possibly requiring the need to
commission surveys and investigations.
These will influence design consideration
of source control, pathway and receptor
(see Chapter 2).
Community engagement is a vital part
of a successful project. Working with
communities through the design, planning
and delivery processes is essential for
finding the best design and building
support for the project. Community
engagement can also act as a catalyst
for partnership, working to benefit longterm
management and maintenance
mechanisms, as well as funding regimes.
The aim should be to achieve the
maximum benefit, accepting that there
will be practical constraints to consider.
This is particularly relevant as SuDS
is an evolving practice, with complex
regulations and potentially high numbers
of stakeholders involved.
Refer to CIRIA C753 The SuDS Manual,
Chapter 7 for a detailed description of the
SuDS design process.
