Army starts work on temporary dam as flooding hits Coulsdon

The worst may be over, but works continue to mop-up after the floods, and to try to reduce the threat of more flooding in the valleys to the south of Croydon.

With the ground saturated from the heavy winter rains, soldiers and engineers construct a temporary dam on the downs at Woldingham to back-up some of the water on the Caterham Bourne

Army engineers were in action again yesterday, constructing a temporary dam in Woldingham near the source of the Caterham Bourne to hold back the water from the past months’ heavy rains and delay its flow downstream towards Whyteleafe, Kenley and Purley – the sort of action which some Surrey residents had been suggesting at the start of January when water levels of the bourne were first observed to be rising rapidly.

Some homes in Coulsdon have had their gardens flooded, as the Coulsdon Bourne – carrying waters running off Farthing Downs, near Coulsdon South Station – has burst its banks.

The A22 remains closed, with work going on overnight between the junctions of Hayes Lane and Little Roke Road – some of it including boxing in the lengthy pipes that had been pumping flood water away from the Kenley water treatment works. The council and Transport for London are looking at the possibility of re-opening the Godstone Road from Hayes Lane to St James Road before Monday morning’s  rush-hour.

Croydon Council has not updated its flooding emergency page on its website since Friday. A flood advice centre has been set up by the council and other agencies to help those affected by or worried about flooding. Based at the Safer Neighbourhood Team hub at 9-11 Whytecliffe Road, it is open 10am to 4pm on Monday and Wednesday, and 10am to 2pm on Saturday, and will operate until March 5.

On Monday, the advice centre will be attended by an advisor from Thames Water (noon to 4pm).

  1. John O'Brien says:

    This is an exercise in futility as the flow of water down Hallilloo Valley is already stored in three natural lakes on the golf course and on Bug Hill Farm.

    The main flow of water running down the road to Wapses Lodge is coming from Marden Park Valley and is ongoing. The black pudding by the rail viaduct (similar to the “Chertsey sausage”) will serve no useful purpose at all.
