Decision details

The coastal defences across Cardiff’s foreshore are in very poor condition and erosion is already taking place at a rapid rate.

An Outline business case has been produced aiming to improve the existing coastal and fluvial defences to provide improved protection to people and property in southeast Cardiff from coastal erosion and flood risk, and prevent the erosion of two decommissioned landfill sites and Rover Way adopted highway.

Much of the coastline across the project area is eroding and with predicted sea level rise due to climate change, the flood and erosion risk will increase into the future. The proposed scheme will manage flood risk to 1,116 residential and 72 non-residential properties over 100 years, as well as preventing further erosion. The scheme is a combination of rock armour, raising of embankments and sheet piling.

Approval is being sought for the project to proceed to Detailed Design as part of the Welsh Government Coastal Risk Management Programme.

RESOLVED: that

1.          the detailed design and construction of the coastal defences valued at £11M be procured.  The funding to be provided on an apportionment of 75% funded by Welsh Government and 25% by Cardiff Council.

2.          the 25% funding required to deliver the coastal defences be committed in line with the Welsh Government Coastal Risk Management Programme.

3.          a reassessment of the scheme be undertaken following the completion of the detailed design to confirm financial implications of construction and viability.
