Sanway-Byfleet Flood Alleviation Scheme

This Environment Agency scheme gives better protection from flooding for people and properties in the Sanway area of Byfleet. There will be new flood walls, embankments and storage areas for displaced flood water. We will be improving habitats and biodiversity and making recreational enhancements such as access to Common Meadows and Manor Farm.

  • What we've been doing

    Exploring a route for construction traffic

    We know how that construction traffic is an important topic to residents.

    Now that the M25 junction 10 works are complete there is a possible alternative haul route that could be used to take soil offsite from areas south of the river Wey. This new route could help reduce the amount of lorry movements leaving our site via Mill Lane.

    We are working closely with Surrey County Council and National Highways to explore this new haul route for our scheme.


    Getting funding

    The scheme is expected to be funded by government funding (known as Grant in Aid - GiA) from Defra, alongside contributions from partners as outlined below.

    Partner

    Funding amount

    Surrey County Council

    £1.68 million

    National Highways

    £1.5 million

    Thames RFCC

    £4.98 million

    GiA is currently under pressure nationally due to a lot of projects applying for funding. This has meant that there is limited availability over the next year. Partnership funding enables the project to keep progressing at this time and improves our ability to secure GiA for future years. Opportunities to secure other partnership funding sources are also being actively explored.


    Streamlining our design to achieve a resolution to grant for planning

    This is a formal decision made by the local planning authority agreeing to approve a planning application, allowing us to draft the legal agreements required before the official planning permission notice is issued. We are updating our drawings to include the identified cost reduction opportunities so that our application can be reviewed in the December Planning Committee.

  • New government funding policy

    18/12/2025

    There is a new approach being introduced by Defra in April 2026 that will change how both new and existing Flood and Coastal erosion risk management (FCERM) schemes are funded. This new approach proposes some principles relevant to our scheme:

    • First £3 million covered: All FCERM projects get full government funding up to £3 million
    • Above £3 million: Project costs beyond that are 90% funded. However, funding will not be provided for elements that do not contribute to reducing flood risk, such as our proposed new ‘Garden Route’ bridleway. We know that these elements remain popular with people and we want to retain community support for the scheme.
    • Projects will be prioritised by value for money, worked out by a set benefit to cost ratio.

    This means that there is potential for our scheme to receive more government funding than under the existing formula. However, there will be many projects across the country applying for money. We await full guidance for how the new policy will be implemented and how schemes will be prioritised.
