A wooden groyne is to be trialed at Buffalo Beach, off the end of the already completed stage two rock seawall, announced today the Thames-Coromandel Council.
It’s expected the groyne will promote enough sand build-up towards the north of Buffalo Beach to negate the construction of a further rock seawall as well as allow for more dune planting.
The structure will be designed to allow for pedestrian access, so people can still walk along the beach unimpeded.
Engineering company Tonkin and Taylor Ltd. has been commissioned to design and obtain resource consent for the trial groyne.
The council also announced that the construction of a sloped rock revetment wall at Purangi Reserve Cooks Beach, which will blend into the existing rock wall, has won the support of the Mercury Bay Community Board. A wall is needed to protect the reserve (the waterpump station, stormwater reticulation, and to a lesser extent at this present time, Captain Cook Road) from the effects of coastal erosion.
Since June 2013 up to 10m of the reserve has been lost to erosion and resulted in the relocation of the Cook monument.
