The Master Plans are one of the main tools for sustainable urban development to counter the effects of growing urbanization in the cities. But, at the same time, the process of its preparing is the challenge to those concerned, especially in the absence of standards that embody the principles of urban sustainable. So, research started from the issue of developing contemporary standards for preparing a sustainable master plan that achieves the terms of Sustainability, and it adopted a reference study about the terminology and theoretical concepts related to sustainable urban development, principles and sustainable master plan and its objectives and areas of work. It adopted the International Planning Standards adopted by various countries and international organizations specialized in preparing Master Plans that contribute in creating more sustainable cities. In the case of Latakia, it was found that the Master Plan, which was prepared in 2008 according to the Proposed Schematic Program for land uses, achieves only (51%) of the conditions of sustainability; this figure does not meet the needs of Lattakia in the short term and long term; it is also clear that the administrative side of the planning operation is the main reasons that led to the unsuccessful master plan; in other words, the work, according to the traditional planning standards and the limited laws and legislations, is not enough, but must be accompanied by action planning and contemporary administrative standards based on urban sustainability.
