The North-West coast, NWC, of Egypt represents one of the longest coasts in the country; which extends from Alexandria in the east for 520 km to El-Salloum on the Libyan border to the west. The development plans have been lunched into the zone which is concerned with industrial, agricultural, mining, touristic, and environmental activities. The current study is concerned with studying the management of the different proposed development sectors in the coastal zones. A Strategic environmental assessment model, SEA, has been designed to formulate the correlation between the scoped factors of the study based on weighing forces of each on the other and on the whole process. The studied NWCZ has a fragile nature as a dryland and it is exposed to the deforestation phenomenon which may affect all the proposed future development plans. So, The agricultural and environmental proposed projects for the studied zone were found as the most positive projects for the area where they recorded 13 and 50 as numerical values; respectively. While; the industrial, mining, and touristic proposed activities, have recorded -38, -40, and -5, respectively.
