Have included the Beirut (western) Marina, a breakwater and a two-line defense structure, with the eastern marina planned in Phase Two of the BCD development.
The defense structure:
Submerged reef as first defense line extending 100 m seawards along the full extent of the Corniche-80 reinforced concrete caissons, each 17.5 m wide, 27.75 m long and 10.5 m high, as second defense line. The superstructure provides two-level promenades over 1.3km. Backfilling behind them provides a stabilizing bond and a third promenade, 5.5 m above sea level.
Design features: seafront construction below 5.5 m allows sea views from the city center; public access right down to the beach; three-level promenade over the caissons.
