The Palm Jumeirah consists of a 'trunk', 'crown', and a surrounding 'crescent' island that will forms an 11 kilometer-long breakwater. The island itself is 5 kilometers by 5 kilometers. It will add 78 kilometers to the Dubai coastline. The first phase of development created 4,000 residences. Residents began moving into the Palm Jumeirah properties by the end of 2006, five years after land reclamation began, according to project developer Nakheel Properties. This signaled the end of phase one of construction, which included approximately 1,400 villas on 11 of the fronds of the island and roughly 2,500 shoreline apartments in 20 buildings on the east side of the trunk.
