FOCUSING ON FLOOD AVOIDANCE

We need to build into our communities the resilience to cope with flooding - sadly in a warmer wetter world - flood events are going to become more common. Over the weekend some 27 flood warnings were issued for Wales. Over the last five years the Welsh Government has invested more than £390 million to manage flood risk. The  severity and frequency of flooding events means that flood prevention needs to become a strategic national priority.

Both the Welsh and Westminster Governments need to make rational long term sustainable choices when it comes to flood defence. We in Wales need to develop a comprehensive planning system for our country that hardens our communities and infrastructure against the effects of severe weather events.   We need to focus on flood prevention and develop flood preventative schemes rather than end up clearing up after the flood is over again and again.

As our winters and our summers become warmer and wetter we will see more instances sea and riverine flooding, persistent bad weather has meant that some of our communities have had some pretty close calls and other communities have been badly inundated (again). There can be no blank cheque for flood defences so we need to make rational cost effective sustainable choices when it comes to flood defence whether for coastal or riverine flooding on the Gwent levels or the Ebbw, Wye, Usk or Monnow valleys. 

The debate taking place around flooding needs to focus on re-engineering the whole water system in Wales to ensure that water is retained in the uplands to prevent downstream flooding. Here in Wales, those agencies responsible for our environment need to take the lead and work to ensure that potential flood waters are retained our uplands for longer and flood prevention avoidance schemes are comprehensively built into our planning system.

Where possible we should avoid building in those areas that are particularly vulnerable to flooding or at least when building to take into account the possibilities of flooding. If we are going to build on flood plains or other areas that are vulnerable to flooding then we must use flood resistant or at the very least flood hardened modern intelligent design techniques to limit potential damage, loss and inconvenience as are used elsewhere. The on-going Dutch programme - Room for the River shows what’s possible.

We can be constructively innovative when we want to - the Welsh Government had previously given “indicative approval” to the Upper Conwy project. The purpose of the project is to assist in the storage of flood waters in the upland by slowing water flows through the restoration of moors, and it includes ditch blocking and river restoration. The cooperative project is spearheaded by Natural Resources Wales and the National Trust, with an agency official seconded to the Trust to push the work forward. Similar schemes have been developed in the north of England - this is good practice and we need much more of this.
