In November 2002, the Caesarea Development Corporation constructed a large earthen embankment running the length of the 160 meter-wide corridor between Jisr az-Zarqa and neighboring Caesarea. The embankment was built to block noise from the muezzin in local mosques, celebratory gunfire, and to reduce property crime in surrounding communities. Residents of Jisr az-Zarqa claim that the national park in the north, the embankment to the south, the highway to the east and the sea to the west, are keeping the town from expanding.
