In 2011 a £6m coastal defence scheme is being constructed in Colwyn Bay. The following changes have been made to the existing coastal defence scheme:

URBANE research on habitat enhancement

The URBANE team have been working with Conwy Council, the Seacams partnership and RPC Concrete Solutions to incorporate large-scale pre-cast habitat enhancement units called “BIOBLOCKS” into the new coastal defence scheme at Colwyn Bay, North Wales.

The BIOBLOCK was deployed in February 2012. It weighs approximately 6 tonnes with dimensions of 1.5 x 1.5 x 1.1 m.

A variety of habitat types were incorporated into the BIOBLOCK during the casting process including rock pools of varying diameters and depths on the horizontal surface, pits of varying depth on two of the vertical sides and longitudinal crevices on the other two vertical sides.
