ICE Wales Cymru North Wales Branch Mill Lane presents a webinar on the Beaumaris Flood Risk Reduction Scheme.

Following internal flooding to 17 properties in 2004, a flood alleviation scheme was completed by Isle of Anglesey County Council in March 2007. Flooding occurred again in September 2007, with six properties suffering internal flooding.

Despite improvements to the inlet, a further event occurred in December 2012. No internal flooding was reported but the A454 was closed causing diversions and disruption to residents. The most recent flood event occurred in November 2017. During the incident, roads were flooded and residents along Mill Lane were evacuated.

In all instances of flooding, a trash screen was prone to blockage. Flooding to properties and the highway infrastructure could only be avoided when operatives were able to clear the screen during each event. It was found that the screen was unsafe to maintain during an event, and despite best efforts, flood water overtopped riverbanks resulting in internal flooding.

Flood risk reduction

Waterco were commissioned to develop proposals to reduce flood risk and generally make the area safe to maintain. As part of a pilot project, an automated screen was installed in August 2020. The screen is the first of its kind in Wales and sixth in UK.
