Hastings Coastal Protection Scheme Moves Forward
Mackley is making good progress with a scheme designed to maintain the structural integrity of the harbor arm in the historic town of Hastings on the Sussex coast, the company said in their latest release.
Under the scheme, which is being carried out on behalf of Hastings Borough Council, 6-9 tonne rock armor with crest level +5.5m OD will be placed at a slope 1 in 1.5 against both west and east sides of the harbor arm structure, and on top of the middle part of the structure where there are gaps.
The existing ‘stabit’ breakwaters and broken concrete surrounding the structure will be restacked to form the core, together with 0.5 -1.0 tonne rocks to the base of the armor layers.
Work on the inner section of the harbor arm has already been taking place. This has involved re-facing the structure with 300mm thick concrete – a total of 340m³ of concrete. This element of the works is now complete, said Mackley in the update.
Shaun Cooper, Mackley Project Manager for the scheme, said: “The harbor arm structure has two very important functions. First to retain Hastings’ main amenity beach to the west, which also serves as part of the town’s sea defense system offering protection to the highway and building infrastructure, including the proposed new development at Pelham Place.”
Following a break for the winter weather, Mackley will return in the spring to complete the project with the placing of the rock.
