Strengthening DefencesWe have been developing a programme of works to reduce flooding from

rivers and surface water.

• Consulting, planning and constructing flood alleviation schemes for Mytholmroyd and Hebden Bridge.

• Calderdale Council are identifying where there is not enough capacity in existing surface water drainage systems.

• Environment Agency and Yorkshire Water are working to identify reservoirs that could help reduce the risk of flooding.

• Canal & River Trust are exploring whether canals can be used to protect against flooding.

• Yorkshire Water are improving sewer networks.

• Slow the Flow are promoting sustainable urban drainage systems.

Calderdale Flood Partnership - reducing the risk of flooding for Calderdale

£30 million flood alleviation scheme for MytholmroydThe main elements are:-

New, raised, and improved flood

walls;

Widening of the river channel at

St. Michael’s church;

The relocation of Caldene Bridge to

enable river widening;

Strengthening and waterproofing

buildings next to the river.Demolition of three houses



• Members of the public shared their

ideas and thoughts about the

proposals.

• Scheme options are accessible at http://eyeoncalderdale.com

• In July 2017 we held a consultation

event at Hebden Bridge showing

options for the scheme.

Hebden Bridge

Reservoir management to reduce flooding• The Environment Agency and Yorkshire

Water have completed an exercise to

identify reservoirs that could be used to

help reduce flooding.

• There are a number of technical,

environmental, legal and regulatory

challenges to overcome.

• The Environment Agency, United

Utilities, Yorkshire Water, DEFRA and

OFWAT have established a working

group to look at potential use of reservoir

storage.

• A regional study is ongoing to

understand the impacts of using these

assets on water supply.


Flood Risk Reduction Schemes Phase 1 (FRRS1)

• Erringden Hillside works will be part of the Hebden Bridge flood

alleviation scheme to increase design and construction efficiencies.

• Park Road, Elland - work is continuing to develop the business case

to reduce flood risk to homes and businesses.

• Flood Risk Reduction Works are now complete at the following sites:

• Shop Lock, Todmorden• Nutclough, Hebden Bridge• Bacup Road, Todmorden• Pin Hill, Midgely• Woodland View, Hebden Bridge

• Work at Burnt Acres, Eastwood to improve highway drainage is expected to be complete by the end of September 2017.


Flood Risk Reduction Schemes Phase 1 – completed schemes

Completed the installation

of a new access ramp and

the construction of a new

wall to retain the ramp at

Shop Lock, Union Street,

access steps on Bacup Road

Surface water collection system on

A681, Bacup Road

There are 22 sites along a 3.5km stretch on Bacup Road,

Todmorden. The project was completed in May 2016 and reduces

flood risk to 109 residential properties.


• The Environment Agency held four

community drop-in events at Brighouse,

Sowerby Bridge, Hebden Bridge and

Todmorden in June 2017.

• The events were attended by other

partners including Calderdale Council,

Canal and River Trust, Northern

PowerGrid, Yorkshire Water.

• The drop-ins provided an opportunity for

local communities to give their knowledge

of the sources and extent of flooding to

support initial FRRS2 assessments.

Flood Risk Reduction Schemes Phase 2 (FRRS2)

Flood Risk Reduction Scheme Phase 2 possible projects

You Can Slow The Flow! SuDs(Sustainable Drainage systems)

Sustainable drainage systems (SuDS) mimic the natural cycle of water

management by retaining water where it lands (instead of shedding it

quickly to drains and watercourses, which can lead to floods). Slow The

Flow Calderdale is raising awareness of how this can be achieved by

everyone in their urban environment at home, at work, at school and in

public places.

Calderdale Council – road gully improvement

• Around 1,300 road gullies in Calderdale will be repaired or replaced

after Calderdale Council successfully secured nearly £1 million from

the Department for Transport (DfT) to boost local flood defence

work.

• Calderdale Council will spend its £1 million funding on 10 major

roads throughout the borough: the A629 Keighley Road, A629

Calderdale Way, A646 Skircoat Moor Road, A646 Todmorden Road,

A644 Wakefield Road in Brighouse, A646 at Hebden Bridge and

Mytholmroyd, A62 Cooper Bridge, A58 Whitehall Road in Lightcliffe

and the A58 Ripponden.


Ongoing Environment Agency maintenance

Natural Flood Management (NFM)

Natural flood management aims to manage the landscape to slow the flow of water, this includes:

• Understanding the relationships between catchment

management and flooding.

• Delivering NFM techniques which can contribute to flood

reduction and alleviation - water storage, planting trees, changing

land management.

• Working with land owners and land managers to contribute to

solutions such as stewardship schemes to support flood

management techniques.

• Influencing government policy and ensuring adequate regulation.


Tree & Woodland Strategy

• The TWS 2017-2027 & associated action

plan is now in draft after consultation with

stakeholders.

• The strategy which outlines an approach to

tree and woodland management across

Calderdale, for the next 10 years, is due to go

to Calderdale Cabinet in November and

hopefully will be finalised and published by

the end of the year.

Opportunity mapping for Natural Flood Management

Natural Flood Management GuidanceWe are finalising natural flood management guidance for farmers,

Resilient Infrastructure

We have been working hard to repair and strengthen key infrastructure to ensure it is operational for future floods, this includes:

• Reviewing the flood risk of roads, railways, water

and power supplies that are locally critical;

• Protecting and maintaining significant infrastructure;

• Setting out maintenance plans and supporting local communities to carry out their own maintenance work.


Energy Infrastructure

• Hebden Bridge energy supply was the area worst affected in

the Boxing Day 2015 floods.

• 80% of businesses were affected.

• In all, seven of Northern PowerGrid sites were affected.

• Two sites suffered disruptive failures, three sites required

maintenance and one needed cleaning.

• Northern PowerGrid has completed repair work at six sites.

• Four substations in Todmorden and Hebden Bridge are being

relocated.

Community Resilience

• Since the devastating floods the partnership has supported the

community in many ways to make sure that people and property

are more resilient in flood incidents.

• Effective warnings are vital and many people have signed up to

get flood warnings. Partners are investigating new methods to

warn communities where river levels rise quickly.

• The partnership have established a network for community flood

action groups and a database of volunteers who can help out

during and after floods.

• Resilience begins with the individual, the householder, the

business.

Flood Warning Area

Mytholmroydflood information centre

• A place where the community can

come and ask questions directly.

• Provides up to date information on

the scheme for residents.

• Information regarding other flood

scheme proposals in the valley.

• The flood information centre is open

every week, Monday 10am - 4pm,

Wednesday 1pm – 7pm and Friday

10am – 4pm, located in the

community centre car park.


Flood wardens down the valley• Our warden groups include Todmorden, Hebden Bridge,

Mytholmroyd, Sowerby Bridge, Elland, Luddendenfoot &

Brighouse.

• In February 2017 partners organised a flood warden network.

• We now have over 60 wardens in Calderdale.


Funded radios for flood wardens

• Calderdale Council and the

Environment Agency have

funded new radios for flood

wardens, this means better

communication links in flood

events.

• Radios will be linked into the

council community hubs this

will ensure wardens can send

and receive messages quickly

& easily in the event of a

flood.


Flood plans for schools & carehomes

• Activity sessions at Burnley Road

Academy including a giant flood

game and ‘show and tell’, which

helped children learn about why they

flooded, this helped them to feel

more prepared if it happens again.

• The school had only recently

reopened after nine months.

• It was also an opportunity for

information to be taken home to

parents and guardians.

• Members of the flood resilience

team visited Mytholmroyd

Meadows, a care home and

sheltered housing for vulnerable

adults and elderly people.

• They also worked with the homes

managers to create a detailed

flood plan for the care home.


Encouraging residents to sign up to flood line

• The Environment Agency sent out a 10,000 mail shot out to all homes in Calderdale that are at flood risk promoting our flood line service.

• Since the mail shot we have had an

increase in sign ups, this means more

households will receive our flood alerts

and warnings & can hopefully be better

prepared.

• Our flood resilience team has been out door knocking encouraging people to sign up.

• Don’t miss out register for flood line here https://www.gov.uk/sign-up-for-flood-warnings
