10 years of the Calderdale Flood Action Plan

In 2026, the Calderdale Flood Action Plan reaches an important milestone: 10 years since its launch following Storm Eva and the devastating floods of winter 2015/16.

Over the last decade, the Plan has helped make Calderdale more resilient to flooding through a combination of flood defences, infrastructure improvements, natural flood management and community action.

This anniversary is an opportunity to reflect on the progress made, celebrate the achievements of communities and partners, and look ahead to the work that continues to build Calderdale’s resilience to future flooding challenges.

To remember the impact of the floods and the journey Calderdale has taken since 2015, watch Storm Eva 2015 – Calderdale Remembers.

Between 2016 and 2026, Calderdale secured approximately £135 million to invest in flood resilience projects across the borough, supporting major flood defence schemes, natural flood management initiatives, infrastructure improvements and community resilience programmes.

Strengthening Defences

Major investment has improved flood protection for hundreds of homes and businesses across Calderdale.

The flagship Mytholmroyd Flood Alleviation Scheme, completed in 2024 at a cost of approximately £41 million, now provides better protection for around 400 homes and businesses.
Recent improvements in Copley Village have enhanced flood protection for more than 200 properties.
Ongoing schemes in Brighouse and the Hebble Brook catchment are expected to improve flood resilience for a further 600 homes and businesses.
Secured planning permission for the Hebden Bridge Flood Alleviation Scheme, which represents a significant step forward in the development of long-term flood resilience measures for the town.

Resilient Infrastructure

Flood resilience measures have been incorporated into key infrastructure to help services continue operating during severe weather.

Schools, including Burnley Road Academy, have benefited from flood gates and other protection measures, helping to safeguard pupils, staff and facilities during flood events.

Leading the Way in Natural Flood Management

Calderdale has become a nationally recognised leader in Natural Flood Management (NFM), helping to slow the flow of water upstream before it reaches communities downstream.

Since 2016:

16,500+ trees planted as part of the NFM Grant Scheme
£2 million+ allocated by Calderdale Council and the Environment Agency to support NFM projects
New wetlands have been created, including at Brearley Fields in Mytholmroyd.
Sustainable Drainage Systems (SuDS) at Ash Green in Mixenden are helping to manage surface water, improve biodiversity and reduce pollution.
6,000+ sphagnum moss plugs have been planted on moorland to improve water retention.

Empowering Communities

Building resilience is about more than physical infrastructure. The Flood Action Plan has helped communities become more informed, connected and prepared.

Eye on Calderdale provides residents and businesses with a trusted source of flood information, warnings, preparedness advice and recovery support.
Calderdale has developed a strong network of volunteer flood wardens, with seven active flood groups supporting local communities.

Working Together

A key strength of the Flood Action Plan has been its partnership approach, bringing together communities, local flood groups, Calderdale Council, emergency responders, environmental organisations and infrastructure providers to reduce flood risk and improve resilience.

This infographic highlights the progress made during 2025/26 and demonstrates how ten years of partnership working, investment and innovation have helped make Calderdale more resilient to flooding, while recognising that the work continues as we adapt to future challenges.
