Oxford Alleviation Scheme gets go ahead

The much-anticipated Oxford Flood Alleviation Scheme is one step closer to becoming a reality following Oxfordshire County Council’s resolution to grant planning permission. This pivotal decision, subject to standard regulatory requirements, represents a significant milestone in the effort to mitigate flood risks from the River Thames and safeguard the city’s homes, businesses, roads, and railways.

Led by the Environment Agency in collaboration with nine partner organisations, the Oxford Flood Alleviation Scheme is one of the most ambitious flood defence projects currently planned in England.

The Environment Agency engaged Gillespies’ landscape planning team in 2015 to conduct a comprehensive Landscape and Visual Impact Assessment and design the landscape for the flood mitigation project west of Oxford city centre. Collaborating closely with lead engineer Jacobs, the team crafted plans to establish new flood channels and defences within Oxford’s historic flood meadows. This strategic approach aims to channel floodwater away from developed areas, significantly reducing flood risk and enhancing resilience over the next century.

A new stream, fed by the River Thames, will meander through a gently sloping floodplain comprising grazing meadows, wildflowers, and rich wetlands. This picturesque area will establish diverse new habitats for flora and fauna, while dedicated walking and cycling paths will invite residents and visitors to enjoy the stunning views and abundant wildlife.

During periods of high water levels in the Thames, the new stream will channel water into the lowered floodplain, preventing overspill into the city’s built-up areas. This innovative approach will provide natural flood relief while enhancing the ecological and recreational value of the flood meadows.

Given the importance of the flood meadows to the character of Oxford, it was crucial to ensure that the scheme not only preserved the site’s amenity and value but also actively enhanced its setting and broader landscape contribution, .

The approval is subject to the application being referred to the Secretary of State for the Ministry of Housing, Communities, and Local Government due to the scheme’s location within the green belt. The Secretary of State will determine if further evaluation is necessary. Additionally, the Environment Agency must finalise a legal agreement with the council regarding the management and monitoring of the new habitats created by the scheme.

This comprehensive flood alleviation plan promises to fortify Oxford against future flooding, preserving the city’s heritage and enhancing its natural environment for generations to come.
