two.1.3) Type of contract
Works
two.1.4) Short description
A major flooding event occured in December 2013, and the smaller events in the 2013-2014 winter period saw flooding in Traeth Coch (Red Wharf Bay) not seen for many years. The coastal wall did little to prevent seawater inundating the properties along the frontage, with businesses and residential properties being flooded. The grassed area, and the coastal road were both also flooded, and in many places, the wall is breached by high tides and stormy weather on an almost annual basis.
The Traeth Coch (Red Wharf Bay) Sea Defence Scheme will aim to protect the community from a 1 in 200-year coastal flooding event.
