The Coastal Margin or Lowland is a flat and low plain that faces Manila Bay. Located here is Manila, Navotas, parts of Malabon, and the western part and reclaimed areas of Pasay and Parañaque, where the ground elevation ranges from zero meters on Manila Bay to five meters at the west side of the cities of Mandaluyong and Makati. The Coastal Lowland possesses resources for offshore fisheries and fishpond development, and various reclamation projects in the area are meant for mixed-use urban development.
