Our cottage is rather short, the upstairs rooms being contained mostly by open roof space rather than walls. Also, the house itself is set in the side of a steep bank between Townsend Meadow and the main road, which means the best views (our only good ones) are from the bedroom roof-lights. These windows all face west and overlook the field towards Wenlock Edge and the big sky above.
Much time can pass at these windows, studying cloud movements or the wheeling of rooks and jackdaws. Sometimes the odd soul (with or without companionable dog) walks by on the field path just beyond our garden gate, and sometimes on Monday mornings, the town’s entire ‘walk for health’ mob, several dozen strong with high-vis vested leaders and bringers-up of rear, trails by. Now and then, too, the farmer can also be spotted, driving his latest substance-spraying rig back and forth across the crop (this week it was a top-dressing of fertiliser for the wheat which – after the rain – is already shooting up like multiples of Jack’s beanstalk). So given this general lack of activity out back, the appearance of a big digger and very large dump truck on the near horizon was an exciting event.
The work in progress (over the brow of the hill and out of sight in the field’s top corner) is the excavation of an attenuation pond. (There is another larger one to the south of the town). They are basically reservoir basins, but without water – designed to stem the impact of any flash flood off Wenlock Edge. The town sits in a bowl between the Edge and several hills, and has been designated a rapid response flood zone. This sounds alarming, and indeed could well be, but the conditions for flash flooding are very particular: i.e. if a severe storm hits our catchment after prolonged periods of rain when the ground is sodden, or in winter after hard frost. Water that cannot drain into the land flows into adjacent roads which then act like rivers, speedily conducting the run-off into the town centre. This can all happen in the space of 20 minutes.
As far as we know, and despite its shortness and low-lying position, our house has no history of being flooded. In the last big flood of 2007 the water seemed to flow around us. I watched the rain pour off the garden terraces behind the house, flow by the kitchen door in a fast running stream before emptying on to the main road where it doubtless contributed to the flooding of properties downstream of us.
It was unnerving to see, and later we heard that at least 50 houses in the centre of town had their cellars and ground floors deluged. That evening, coming home from work across the Edge, Graham had to abandon the car on the far side of town and take an upland ‘cross-country’ route home.
How well the ponds will serve us is yet to be demonstrated. After 12 years without a flood, it is easy to imagine that it won’t happen again, though last month The Man from the Environment Agency did come specially to town to tell us we must remain vigilant. As many round the world know to their cost, climate change is responsible for an increase in extreme weather events and, in the most extreme scenario, our ponds will only slow the flow, not stop it. There are probably further measures that could be taken: urging (enforcing would be better) landowners to plant more trees, create more flood plains round water courses, stop selling their land for large housing developments whose roofs and access roads accelerate run-off.
For now, though, all thanks are due to the workforce who toiled, excavating and landscaping the ponds, which may one day save our most vulnerable residents the distress of having to spend a year and more drying out a flooded home. In the meantime, I keep watching the sky over Wenlock Edge. At times when the rain closes in, day after day without let up, it’s easy to wonder: is this flooding rain?
