Objective One areas at greatest risk of future flooding are being helped with a total£12.5m for flood defence schemes. Towns set to benefit include some of those worst hit by last year's floods.

The Welsh Assembly Government's agreement to£5m match funding for flood defence schemes has secured£5m of Objective One money, with the rest coming from local authorities, developers and flood defence committees.

Environment, planning and countryside minister Carwyn Jones announced the funding in Pontardawe, one of the many schemes planned as part of the Environment Agency's 'Umbrella Project'.

Mr Jones said: 'I have witnessed the devastating emotional and economic effects of flooding on homes and businesses, and want everything possible to be done to ensure we minimise the increasing risk of flood damage.

'As a result of flooding, communities may suffer from reduced property prices, increased insurance costs and low confidence, leading to a lack of investment and development.

'Climate change is expected to lead to an increased risk of flooding in the future and in Wales, due to its particular geography, we are at risk from damaging floods with little or no prior warning.'

The following flood defence schemes are proposed for inclusion in the Umbrella Project. The schemes are at different stages of development (e.g pre-feasibility, feasibility, design etc), and ultimately whether a particular scheme proceeds to construction depends upon many factors. Final inclusion of a scheme cannot be guaranteed at this early stage in the project. Proposed schemes that we are unable to progress will be replaced by appropriate others.

Conwy Valley

Afon Ganol





St Clears



Proposed Schemes

Conwy Valley - The communities of Llanrwst and Trefriw adjacent to the River Conwy have a recent history of flooding, with a major flood event occurring in February 2004, during which 125mm of rainfall was recorded over a 14 hour period. A total of up to 50 properties flooded in Llanrwst and the villages of Trefriw, Dolwyddelan and Betws y Coed. Other flooding events occurred in September 2004 and January 2005.

Afon Ganol - currently tidal gates on the Afon Ganol, on the North Wales coast near Colwyn Bay, protect land from tidal flooding on high tides, but when the gates are closed there is a risk of increased fluvial flow leading to flooding. Equally, if the tidal gates fail for any reason, then tidal inundation would occur daily, potentially leading to inundation of 94 properties and changes in water and land quality.

Abererch - the coastal dune system at Abererch protects the existing floodplain of the Afon Erch from tidal inundation. The main railway line and A road are also situated behind the dunes and 63 residential and commercial properties are at risk on the floodplain.

Resolven - the town is situated alongside the River Neath and Clydach Brook, and has suffered major flooding events in 1979 and 1998. There isrisk to life during severe events, due to rapid inundation, and 178 properties (both residential and commercial) are potentially affected, with up to 626 people at risk.

Glynneath - has a history of flooding from the River Neath, with major events occurring in 1979 and 1998. Three areas of the town are at particular risk (approximately 674 properties) are at risk, with return periods of 1 in 30 years or above.

Aberdare - The Dare Culvert conveys the River Dare beneath Aberdare town centre to its confluence with the River Cynon. The culvert is 407m in length and much of it is approximately 140 years old. There are a number of illicit service crossings and numerous outfall connections. A structural survey carried out in 1996 indicated that there were existing structural problems with the culvert with localised undermining of foundations, missing masonry blocks, deterioration of pointing and structural damage to the arch at the locations of the service crossings.

St Clears - major events occurred in 1979, 1985, 1986, 1987 and 1991 resulting in extensive flooding to up to 25 properties adjacent to the river, including both residential and commercial properties, a police station, a medical centre and waste water treatment works. Flood flows back up above Pentre Bridge and some lesser flooding occurs associated with overland flow paths, minor watercourses, surface run-off and surcharge sewers.

Pontardawe - in 1979 the Afon Tawe broke its bank and flooded the area around its confluence with the Upper Clydach River. Consequently, a major capital project was implemented to provide protection to the town to a 1 in 100 years standard. However, over recent years erosion has caused the collapse of a length of riverside wall and has formed a breach in the defence. A number of properties (59 residential and 29 commercial) are now at increased risk of flooding, with a 1 in 10 years standard of protection.
