Collaborative delivery of green infrastructure and water management solutions (e.g. SuDS) in the urban environment can realise multiple benefits including reduced flood risk, improved water quality and biodiversity, greater amenity and enhanced community health and well-being. In March 2016, the CaBA Urban Working Group, in collaboration with the Defra Urban Ecosystem Services Project (www.urbanwater-eco.services) and Ciria (www.ciria.org), hosted a series of workshops designed to build capacity and expertise within CaBA partnerships to help drive greater collaborative delivery within the urban environment.

Natural value in urban landscapes: health and
wellbeing
4. Today
• Health and wellbeing
• Environments and the determinants of health
• Evidence for health and wellbeing values in urban landscapes
• Research and collaboration in the South West
5. Health and wellbeing?
“Health is a state of complete
physical, mental and social
wellbeing and not merely the
absence of disease or
infirmity”
World Health Organisation, 1948
6. Health and wellbeing in the UK
• UK premature death rates, (causes such as respiratory and
circulatory disease) have significantly reduced over the past 50
years
• HOWEVER! Non-communicable diseases are on the rise:
– 5.4 million receive treatment for asthma
– coronary heart disease and stroke biggest causes of death
in the UK
– rates of diabetes rose from 1.4 million in 1996 to 3.1 million
in 2010, and by 2025 it is estimated that it will rise to more
than 4 million
– diabetes alone currently costs the NHS approximately
£1.5million an hour and takes up about 10% of the total
budget
– physical inactivity contributes to almost one in ten
premature deaths, costs of low levels of physical activity to
the NHS estimated to be over £900 million
There is a need for solutions!
7.
8. Whether people are healthy
or not, is determined by
their circumstances and
environment… factors such
as where we live, the state of
our environment… have
considerable impacts on
health… the more commonly
considered factors such as
access and use of health care
services often have less of an
impact
World Health Organisation. The
determinants of health.
9. Environments and the
determinants of health
In 2006, the World Health Organisation (WHO)
estimated that 24% of healthy life years lost
and 23% of premature mortality were related
to environmental factors
Threats…
Climate change, extreme events, urbanisation,
resource demand, poor quality environments,
pollution, etc.
…and opportunities!
Identifying obesogenic, equigenic, salutogenic
environments
10. …the quality of the environment
around us also affects any
community. Pollution, air quality,
noise, the availability of green
and open spaces
…guidance will make clear that
the wider determinants of health,
including the natural
environment, will be a crucial
consideration in developing joint
strategic needs assessments and
joint health and wellbeing
strategies
11. Focus on the beneficial aspects
(salutogenic and equigenic) and
opportunities of higher quality
greener urban landscapes
12. Natural value in urban
settings
• Gardens of Egyptian nobility
• Walled gardens of Mesopotamia
• ‘Solvitur Ambulando’
• Urban parks in the 19thC developed for the health and
happiness of urbanites
• Federick Law Olmstead in the 19thC said the benefits of nature
‘operate by unconscious processes to relax and relieve tensions
created by the artificial surroundings of urban life’
• Sanatoriums
13. Urban natural capital and
health
• Population level associations
between greenspace and
health

and health
Systematic review found some evidence to
suggest that exposure to biodiverse
environments may relate to better health

showed rates of good population heath were
higher in areas with a greater diversity of
land cover types, with greater bird species
richness and in areas with higher density of
protected/designated areas

21. Not all green is beneficial
• Synergistic effect between pollutant concentrations and the health
response to pollen. People who live in urban areas have been
shown to be more affected by pollen allergies (asthma and allergic
rhinitis) than those who live in rural areas
Salmond, J. A., et al. (2016). "Health and climate related ecosystem services provided by street trees in the
urban environment." Environmental Health 15(1): 95-111.
• Urban green space strategies may be paradoxical: while the
creation of new green space to address environmental justice
problems can make neighbourhoods healthier and more
aesthetically attractive, it also can increase housing costs and
property values

making cities ‘just green enough’." Landscape and Urban Planning 125: 234-244

‘Natural’ elements of urban
environments are highly
valued
23. Natural capital
(health) values
• Natural England: £2.1 billion annual savings through averted health
costs if everyone in England had equal ‘good perceived and/or actual
access to green space’
• Benefit-cost ratio of 3.8:1 for urban trees in the city of Davis,
California, and urban street trees in Lisbon have a benefit-cost ratio of
4.48:1.
• Health benefits associated with having a view of green space from
home to have a value of £135-452 per person per year (Mourato 2010)
24. Natural capital
(health) values
• The economic contribution of The Mersey Forest (one of
England’s 12 original Community Forests) Objective 1 funded
programme (total funding £7million) resulted in an estimated
total monetised benefit of £5.5million per year:
25. Health gain
comparisons
• 10 more trees in a city block, on
average, improves health perception
in ways comparable to an increase in
annual personal income of $10,000
and moving to a neighbourhood with
$10,000 higher median income or
being 7 years younger.
• 11 more trees in a city block, on
average, decreases cardio-metabolic
conditions in ways comparable to an
increase in annual personal income of
$20,000 and moving to a
neighbourhood with $20,000 higher
median income or being 1.4 years
younger. Kardan, O., et al. (2015). "Neighborhood greenspace and
health in a large urban center." Scientific Reports 5: 11610.
26. Cost effective?
Environmental factors are
highly modifiable, and
environmental interventions at
the community level, such as
urban and transport planning,
have been shown to be
promising and more cost
effective than interventions at
the individual level.
Nieuwenhuijsen, M. J. (2016). "Urban and
transport planning, environmental exposures
and health-new concepts, methods and tools
to improve health in cities." Environmental
Health 15(1): 161-171.
27. Southwest hotspot for finding
solutions?
Cities are complex systems. Research to elucidate
pathways to better health and wellbeing demands
systems-based, interdisciplinary methods involving
epidemiologists, toxicologists, urban planners,
environmental scientists, mathematical modellers,
engineers, IT experts, social scientists, public health
researchers and health care professionals. (Vardoulakis 2016)

60. Drivers for Change
Our 25-year WaterFuture vision is to;
“prevent sewer flooding of homes, businesses, public spaces
and roads”
However, there are significant challenges to overcome;
“The strategic approach to flood management needs to be
reinforced, combining flood defence with holistic
management of fluvial and surface water risk, and upstream
catchment measures to improve resilience”.
ICE The State of the Nation Infrastructure Report -2014
61. Drivers for Change
Flooding
• Too much water drains from
developed sites too quickly
• Water ends up in sewers,
highway drains and rivers too
quickly
Water Quality
• Surface runoff is polluted
Environmental Problems
• Loss of habitat, biodiversity
and green space

• Working with parish council, the school and householders to
reduce amount of surface water entering combined sewer.
• The project has three strands:
• Building new surface water sewer and swale to take rainwater from
the school, car park and Memorial Hall to the stream
• Building WSUD features at the school
• Installing free SuDS features at individual properties by running a
‘Reverse Auction’ with residents.
74. Lessons Learnt from Pilots
• Medium or long term alignment of plans
• Financial risk greater for public bodies
• Engage the public at an early stage

98. • Under Schedule 3 of the Act, SuDS
(Sustainable Drainage Systems)
Approval Bodies would require the
County Council to approve and adopt
SuDS for new developments.
• It was announced in December 2014 that
this would not be enacted and SuDS
would be dealt with by strengthening
existing planning policy instead.
– Re-enactment remains a possibility.
Legislation Changes and Implications
99. As part of the Local
Planning Authorities’ role in
determining planning
applications, the LPA must
make the final decision
about the suitability of the
SuDS provision and
whether it is proportionate
to the level of flood risk
affecting the development.
Source: Devon County Council (2012)
Legislation Changes and Implications
100. • Statutory consultee for ‘major
developments’ which have surface water
implications.
Devon County Council’s Role
Commenting on ‘Major Developments’
101. ‘Major development’ is defined by the Town and Country Planning
Order 2015 as development involving any one or more of the
following:
(a) the winning and working of minerals or the use of land for mineral-working deposits;
(b) waste development;
(c) the provision of dwellinghouses where –
(i) the number of dwellinghouses to be provided is 10 or more; or
(ii) the development is to be carried out on a site having an area of 0.5 hectares or
more and it is not known whether the development falls within subparagraph (c)(i);
(d) the provision of a building or buildings where the floor space to be created by the
development is 1,000 square metres or more; or
(e) development carried out on a site having an area of 1 hectare or more.

111. Some challenges around urban diffuse
• Variable and widespread with no one major cause.
• Embedding behavioural change in the public in
difficult
• Capital works, such as large scale retrofit SuDS,
are expensive.
• There is no one party responsible to deliver, there
is multiple ownership. Multiple reasons for failure.
• Those best placed to act may not be the most
responsible or be resourced to act
• ‘Beyond reasonable doubt’
• Current regulatory powers were not designed to
tackle the problem
• Who should pay?
112. Legislation
Is not strong in this area
Water Framework Directive
Prosecution for pollution
Permits to discharge
SuDS are now within the NPPF

Value
MorphologyWQ
114. It is all about
114 And getting the best value for it
118. Conclusion
It is a complex policy area
Strong focus on multiple benefit beyond water quality to
maximise the return on investment
This isn’t cheap and it isn’t quick
Tackling pollution and physical modification together is a
good approach
The opportunity lies with the community and its local
authority...
121. Legislation and policy on green infrastructure and sustainable
drainage
The National Planning Policy Framework supports sustainable drainage,
sustainable development and development resilient to climate change.
Schedule 3 of the Flood and Water Management Act 2010, which has not yet
been brought into force, includes:
• End the automatic right to connect to
public sewers.
• A SuDS Approving Body (SAB) is created
in unitary or county councils to approve
drainage systems in new (re)development
before construction begins
• National Standards published for design,
construction, operation and maintenance of
SuDS – to form the basis of SAB decisions.
• Apply to all new developments of over one
dwelling
122. Consideration of sustainable drainage systems in new development was
considerably weakened by Government action in April 2015
(England only).
Legislation and policy on green infrastructure and sustainable
drainage
• Non-statutory SuDS standards
published – only 2 pages
• Automatic right to connect surface
water run-off to remain.
• SuDS to be brought under local
planning authorities not SABs
• SuDS to be included in large
developments where appropriate;
no requirement on small
developments (<10 dwellings)
Wales has been much more progressive providing detailed interim standards on
SuDS – take a look, they’re good
http://gov.wales/docs/desh/consultation/150212-suds-consultation-en.pdf
123. The Housing and Planning Bill
The Housing and Planning Bill is
currently at committee stage in the
House of Lords.
It aims to address the need for
more, affordable homes – but they
should also be resilient, high quality
homes. Instead, the Bill pursues
rapid building at the expense of
long-term planning.
DEFRA acknowledges SuDS are cheaper to build and maintain (or need be no
more expensive) than is required to maintain conventional drainage.
WWT and others are seeking an amendment (no 119) in the Bill to bring
section 32 of the 2010 Act into force, which would bring Schedule 3 on
Sustainable Drainage into effect as described in the second slide.
124. Opportunities
• Support amendment 119 in the Housing and Planning Bill - write to the
minister, tweet, or contact us conservationpolicy@wwt.og.uk
• Drive SuDS through parliament – get them discussed in the Flood Resilience
Review, the National Infrastructure Commission, the Environment Audit
Committee, CLA and DCLG
• Use the RSPB/WWT guidance on SuDS for multiple benefits to assist with
decision making
http://www.wwt.org.uk/uploads/documents/1400927422_Sustainabledrainagesystemsguide.pdf
• Develop planning authority SuDS guidance document. These are usually in
the form of Supplementary Planning Documents (good examples from Essex
County Council, Cambridge City Council, Southwark Borough Council, Central
Bedfordshire Counciland Ashford District Council)
• Use local plan references to green space, biodiversity, health and well being,
climate change and sustainable development; if you have yet to develop a
local plan make sure that green infrastructure and biodiversity is a key feature

• ‘location and scale of SuDS’
• Flood Risk
130. Our Approach
Making a healthy and desirable place where people want to live, work and visit
• CIRIA SuDS Manual
– Local Guidance (DCC &TDC)
• Multi-disciplinary team – rarity?
– Drainage
– Green Infrastructure
– Biodiversity
– Play
– Urban Design
131. Challenges to Delivery
Making a healthy and desirable place where people want to live, work and visit
• Loss of vision during the planning process
• Appropriate expertise – wrong emphasis
• Resources – LLFA, LPA, Consultant
• ‘Cost/Benefit’ – Economic Viability?
• Communication
• Health and Safety
• What are SuDS?
• Good Quality Examples of SuDS...?
• Legislative Backing
132. Solutions
Making a healthy and desirable place where people want to live, work and visit
• Developing clear, robust local guidance
• Maintaining a multi-disciplinary team
• Working closely with developers and consultants
• Engaging early on in the process
– Linking back to ‘four pillars of SuDS design’
• Strategic SuDS
– Greater detail at outline?
133. Final Thought
Making a healthy and desirable place where people want to live, work and visit
SuDS Maintenance
• Reluctance by Water Companies or Local Authorities
to take on the ‘risk’
• Often left to maintenance companies
– Ongoing monitoring of this?
– Maintenance costs – ‘Economically Proportionate’
– No clear fee structure
– Unregulated
• Could this add to socio-economic deprivation?

SuDS are now well and truly in the
Hollickwood consciousness, and also of all
our community guests, (I see that all the
parents' Facebook pages are going crazy
tonight with admiring comments about
our SuDS!).
