There had been a history of flooding from the River Great Ouse at St Ives and Hemingford Grey & Hemingford Abbots. This project comprised improvements to existing flood banks and flood walls, the construction of new flood banks and flood walls, the provision of six manually operated flood gates (closed during high river flows) and the construction of a small land drainage pumping station in Hemingford Grey. In total 4.25 km of improved or new flood defences were provided.
Prior to this project many areas in St Ives and the Hemingfords were at risk of flooding from events having a 3.3% (1 in 30) chance of flooding in any year, although there were some areas where the annual chance of flooding was as high as 10% (1 in 10). This project has now provided St Ives and the Hemingfords with a minimum protection standard of 1% (1 in 100) chance of flooding in any year.
We have now completed work on the St Ives and Hemingfords Flood Alleviation Scheme. Construction work took place between August 2005 and October 2007.
A total of 1,611 residential properties and 160 commercial properties received an improved standard of flood protection. In addition 212 properties (flats) benefited from gaining a reduced flooding frequency of the accesses to these flats. The overall project cost including construction, design, supervision, administration and compensation to property owners adversely affected by the works, was £9.3 million.
