Design elements

AECOM have been appointed to design the scheme. Their inital drawings are shown below (click on the drawings for enhanced view):

Glandwr Road section

Beach Road East section

Welsh Water pumping station section

Promenade section

We are still working on these designs, and elements of the design are likely to change before final versions are agreed. The final versions will appear on this page within the next few weeks.

Business as usual

If no improvements are made, flood modelling has shown that approximately 47 properties are at risk of flooding if a 1/200 year flood event were to occur today.

Factoring in sea level rise by 2055, this number could rise to 267 properties, 17 of which are commercial.

The diagram you see here represents a 1/100 year flood event with current, and 2055 sea levels.
