The bigger picture in water
management
Ø  Why planning for water matters
Ø  How policy and plans join up
Ø  Who is involved
Ø  Opportunities to get multiple benefits
through partnerships and innovative
approaches

Planning for water: why does it
matter?
Too much, or too little water is bad
for business, the economy and
society:
Ø  lost production and sales
Ø  disrupted transport
Ø  waste of resources
Ø  poor quality environment and
social problems
Good planning and urban design
Ø  reduces flooding
Ø  increases water resilience
Ø  improves water quality
Ø  creates more liveable places

CURRENT ASSETS
Land-cover Composition
Green Wedges
These areas of land offer a space for recreation and nature
conservation, providing a “green lung into urban areas”. They
have been included in the planning policy for Leicester and
Leicestershire for many years.
River Sence
This is the longest tributary
of the River Soar at around
~28km in length.
This map shows the main areas of natural infrastructure
across Leicester and the surrounding wards. There is a
diverse collection of natural habitats and green/blue
spaces across the area; including the wetlands and
riverine habitats to the north of the city, around
Watermead, and species-rich grassland to the
south at Aylestone Meadows Local Nature Reserve.

LOCALACTIONPROJECT
CURRENT ASSETS…continued
These maps illustrate the high level of detail that is available for mapping green and
blue infrastructure, in Leicester. Data is mapped for two example wards; Rushey
Mead Ward and a detailed section of Abbey Park and the surrounding area in
AbbeyWard.
Due to the detailed mapping and high resolution datasets provided
by Leicester City Council, we are able to view features such as outdoor
sports areas, play areas and street trees.

NATURAL CAPITAL

LOCALACTIONPROJECT
BENEFITS ASSESSMENT
To target and implement interventions that enhance natural capital effectively have
developed a series of metrics that assess the current benefits being
experienced by people and the environment.
Each metric is a measure with the potential to be
enhanced through natural solutions.
Access to Green Space
Percentage of people that meet the criteria outlined in Natural
England’s ANGSt (Accessible Natural Greenspace Standard).
Air Quality (PM10)
Mean concentration of PM10 modelled
for 2016, derived from background
maps from the UK-AIR data archive.
Flood Risk (Rivers and Sea)
Number of buildings that have a
greater than 1 in 100 year chance of
flooding from rivers and/or sea.
WFD Ecological Status
The 2014 Water Framework Directive
ecological status for the surrounding
river waterbody catchment.
Average House Price
Mean price for a two-bedroom
house in December 2015.
Flood Damage Cost (Rivers and Sea)
Estimated costs incurred due to flood damage
from rivers and sea, based on figures used in the
EA National Flood Risk Assessment (NaFRA).
Aesthetic value of landscape
Number of nature-related photos taken in
the area that have been uploaded to Flickr
and tagged accordingly.
Cultural Activity
Number of recreational facilities per 1000 people,
including places such as allotments, sports clubs.
Flood Risk (Surface Water)
Number of buildings that have a
greater than 1 in 100 year chance of
flooding from surface water.
Climate Regulation
Percentage of land area that is carbon
/GHG-sequestering habitats of
woodland, grassland, wetland or scrub.
Priority Habitat
Percentage of ward area that is
described as a priority habitat in
Natural England’s Priority Habitats
Inventory.
BENEFITS
• Ward-scale analysis
• Metrics represent range of
values in Leicester
• White spaces represent
opportunity for improvement
Low Flows
The water availability value of river
waterbody catchments, according to
the EA’s Catchment Abstraction
Management Strategy (CAMS).

OPPORTUNITY AREAS
The final step of this assessment is to identify key areas for improvement and
investigate areas of priority, opportunity and feasibility for implementing
measures at these sites.
1. Key areas of opportunity across Leicester, such as potential development
sites (including regeneration and brownfield sites) and proposed
wildlife sites.
Potential Sites for Nature
Potential for expanding local sites for nature in
Leicester. There are a number of proposed Local
Nature Reserves and Local Wildlife Sites, which if
designed effectively could produce a number of
benefits for the wider area.

3. Perform high resolution hydrological and suitability analyses to identify candidate sites
for specific interventions – these sites can then be ‘worked-up’ with resource/funding
sought, community consultation,optioneering, design and delivery.

LOCALACTIONPROJECT
URBAN TOOLBOX
Splits into FOUR broad approaches -
• Restoration / regeneration of urban environments
• GI or SuDS in new development
• Retrofit or greening actions
• Increased functionality – e.g. increased amenity or
access
• For each intervention we have developed
factsheets including cost and benefits info
AND include opportunity/feasibility criteria to
facilitate mapping/scenario development

LOCALACTIONPROJECT
Rain Gardens are usually small vegetated depressions in
the ground created mainly in residential areas to take
surface water run-off from roofs and hard surfaces.
RAIN GARDEN
Infiltration, bio-retention, soakaways
+ They but can vary significantly in size and are sometimes also called
‘bio-retention cells’
+ Aid infiltration by slowing water down and increasing soil permeability
+ Reducing runoff through root uptake of water and transpiration
+ Can act to remove pollutants from water – especially if wetland areas
are incorporated into the design
+ Aesthetically pleasing and can improve QoL and landscape value
IMPLEMENTATION
Rain gardens mimic the natural water retention of undeveloped land and reduce
the volume of water entering drains so they need to be hydrologically connected
Costs: £20-270+/m2 dependent on size and context.
Due to high variability of design and situation.£ £ £
Maintenance: low dependent on context but mainly
litter/sediment removal. Plants need to endure
waterlogged as well as dry conditions.

Ashby Grove residential retrofit rain garden, London
The Ashby Grove rain garden retrofit is designed to remove roof
water from a social housing block in Islington. The aim is to
disconnect one of the roof downpipes and allow water to flow
directly into a newly designed rain garden.

LOCALACTIONPROJECT
Trees can perform a number of functions that in turn
provide a number of different benefits to people in urban
landscapes -
TREES
Street trees, tree pits, urban forest
+ Improving air quality by trapping pollutants
+ Intercepting rainfall to slow the rate of water reaching the ground
+ Increasing infiltration by creating permeable surfaces
+ Reducing runoff through root uptake of water and transpiration
+ Trees are also aesthetically pleasing natural features in an urban
landscape and thus provide many less tangible benefits that improve
people’s quality of life, health and wellbeing
IMPLEMENTATION
Trees are very versatile and can be used in a variety of situations. The benefits
produced depend on their size, species, location and style of delivery.
Costs per singular tree: £100-400
(including planting and initial maintenance)£ £ £
Maintenance: mainly pruning

Urban Forest Effects Model (UFORE) & i-Tree Eco
The Urban Forest Effects Model (UFORE) is a science-based, peer-
reviewed computer model designed to assess and quantify urban
forest ecosystem services, based on field data inputs and external
datasets (e.g. weather and pollution). It was adapted for inclusion
with the i-Tree software suite from the USDA Forest Service, and
was subsequently renamed as i-Tree Eco.

Longitudinal effects on mental health of moving to
greener and less green urban areas.
Alcock I, White MP, Wheeler BW, Fleming LE, Depledge MH.
Environmental Science & Technology (2014) 21; 48 (2):1247-55.
Moving to greener urban areas was associated with sustained mental
health improvements, suggesting that environmental policies to
increase urban green space may have sustainable public health
benefits.
Torbay's Urban Forest
The study (the first of its kind in the UK) used the i-Tree Eco model
(developed by the US Forest Service, and based on peer reviewed
research) to quantify the structure, and some of the major
environmental benefits delivered by Torbay’s trees.
www.torbay.gov.uk/tuf.pdfitreetools.org
StreetTree London
Street Tree is a non-profit making company founded on the belief
that trees should form an integral part of the urban landscape. Our
aim is to increase London's tree stock, working with Local
Authorities, Fund-holders, and business partners, to promote street
trees and the many benefits they bring.
www.streettree.org
Red Rose Forest – Green Streets Case Studies
Red Rose Forest's Green Streets team is dedicated to making our
towns and cities greener and more attractive places to live, work and
invest. They plant street trees, deliver bespoke street greening
projects, create places to grow food, greenspace improvement, plant
community woodlands and orchards, build green roofs and improve
school grounds.

Wirral StreetTrees Programme
A tree planting programme that is helping to transform Wirral into a
thriving economic hub. By April this year over 600 trees across 8km
will have been planted in streets and green spaces, as part of a three-
year programme to link residential areas to places of employment
and training.

Asking
people…
Where does this go to?

Easter Hunt for
Misconnections
•  Residents check
their own plumbing
•  Prizes include a
plumber to fix it.

Engaging to find
Misconnections
•  ConnectRight
•  Helps prevent more
misconnections

Engaging
With local MP
at an urban
makers market

Next Steps
•  Roll out the methodology to other urban areas
•  Already incorporated into three other projects
In Mersey Basin
•  Monitor issues
•  Simple water tests
•  Follow up investigations
Bring in volunteer help locally
•  Promoting this technique
•  Working with CaBA Urban working group
Nationally

Ongoing monitoring
•  Volunteer
citizen science
programme
•  To show
improvements
in water quality

To address Urban Diffuse Water Pollution
issues:
•  Evidence-based project
•  Engaging the public locally
•  Targeting issues found in river surveys
•  Local scale
•  One brook at a time.
More urban surveys

Future
Less of this … and more of this

Beneﬁts

•  Water quality – Average reductions of 67% ammonia, 68% nitrate, 55% total nitrogen. Glenbrook wetlands
reduced average phosphate concentrations by 23% and Chemical Oxygen Demand by 61%. Coliform bacteria
reduced.
•  Flood risk – flood risk reduced for >100 properties in Moore Brook catchment
•  Amenity – diverse landscape with improved access for all users, seating areas and opportunities for natural play,
greening the grey
•  Biodiversity – over 3 hectares of habitat improvements, mosaic of different habitat types including woodland,
wetlands, ponds and meadow
•  Education – several nearby schools using Pymmes Park and Firs Farm Wetlands as an educational resource,
facilitated by Thames21’s Fixing Broken Rivers project. Wonderful Wetlands schools festival in June
•  Transport/Exercise – over 1km of new footpaths for walking/jogging/cycling
•  Safety – transforming neglected sites attracting anti-social behaviour to new green oases for the community
