Godalming has a history of flooding, with 4 notable events in recent years; in 1968, 1990, 2000 and 2013. During the most recent 2013 flood, the Meadrow and Catteshall Road area was flooded. Access from Meadrow to Godalming was restricted.
The Godalming Flood Alleviation Scheme (FAS) is a partnership project between the Environment Agency, Surrey County Council, Waverley Borough Council, Godalming Town Council, Thames Water, Scottish and Southern Electricity and the Godalming Flood Group.
The Environment Agency has assessed flood risk in the area and concluded that, by constructing a flood wall at Meadrow/Catteshall Road Bridge, they can reduce flood risk to this area.
The proposed flood wall with flood gate on Catteshall Road Bridge will reduce the flood risk to at least 90 homes in the vicinity of Meadrow and Catteshall Road Bridge. This will help keep Meadrow open during floods.
Until the permanent flood wall is completed, the Environment Agency intends to provide temporary protection upstream of Catteshall Road Bridge in the event of a flood.
Work so far
The Environment Agency has updated the hydraulic model of the River Wey and Hell Ditch to:
- fully understand how flooding occurs in Godalming.
- help identify a suitable way to protect residents from flooding.
- develop the best solution for the scheme.
- establish that the scheme will not transfer flood risk in the immediate vicinity of Godalming and to downstream communities.
As a result of this work, the scheme will provide a 1:200-year standard of protection to the properties.
Boreholes have been drilled to confirm ground conditions and inform the depth and type of piling required for the flood wall.
The team have identified any potential contamination issues and have monitored groundwater levels.
Ecological and heritage surveys
The team have mapped the habitats in the area, and looked for signs of protected and notable species. They have also identified plants and wildlife likely to be affected by the works.
The team have conducted surveys and assessment of all trees in the vicinity of the proposed flood wall. They have also completed tree root survey using radar techniques to confirm the exact root spread of a protected ash tree.
Appointment of the detailed designer
The team appointed the detailed designer in April 2017 and presented the latest alignment of the flood wall to the community at a Public Information Event on 1 July 2017 at Godalming Football Club.
Cost of the scheme
The total cost of the scheme is approximately £4.2 million. This includes the construction cost as well as the appraisal costs and the lifetime maintenance cost of the wall.
