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.

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

Abbey Ward.

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.

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.

• Ward-scale analysis

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.

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

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.

Islington Raingarden

The Ashby Grove raingarden in Islington was designed and

constructed as a practical example of what can be done in small

landscape spaces as suggested in the Islington SuDS Design Guide.

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) £ £ £

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

Street Tree 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.
