Coastal development is described as changes that are caused by human activities which alter the condition and the landscape of the coastline. Activities of coastal development include the establishment and building of structure which are on, adjacent or near the coast region. It is very alarming as these structures and its associated tasks are the major cause that potentially leads to negative impacts to the coastal and surrounding environment. Thus, coastal zone is defined as the division where the interface between the ocean and land occurs. Besides, it is also described as a zone which changes constantly due to dynamic interaction amidst the ocean and the land (Tulane University, 2013).
The chosen study area is Marina Bay coastal area in Philippines. The coastline of Manila Bay is approximately 190 km long and the coasts are slightly sloping. Manila Bay coastal area plays a major role in the country’s economy. For example, Manila Bay coastal are important in aspect of industry and commerce, agriculture, aquaculture, and tourism. It is listed as one of the country’s oldest traditional fishing grounds. Over the last decades, Manila Bay had been the economic port in terms of activity in trade and transportation. The bay is the second most productive fishing ground in Philippines which is located next to the Visayas seas. In addition, the location of the bay is near to the highest number of population, urbanization, and industrialized area in the country (Perez, 1999).
