The project concerns coastal protection projects in the Local Community (PK) Beach of the Municipality of Katerini, aiming to address the acute problem of erosion of the coasts of the beach, which threatens existing constructions (tourist facilities, hotels, restaurants, etc., as well as private residences). The project in particular includes an extension of existing submerged rocks with a total length of 110 m and replenishing the coast with sand in three areas with a total length of 990 m. and for an average width of about 25 meters. The project will be implemented along the entire length of the coastal front, within the city plan, of the TK Beach of the Municipality of Katerini and will be implemented within 12 months of the signing of the relevant contract.
