One of the main characteristics of Turkey which is one of the countries that is becoming urbanized fast is that the majority of population chooses metropolises and accumulates in metropolises rather than medium sized cities. In this sense, there are specific problems such as basic urban services especially in metropolises. Therefore, there is an increasing need for enhancing spatial life quality of urban settlements in turkey, strengthen economic and social structure, restructuring spatial planning system in Turkey. It was projected to prepare “Urban Development Strategy and Action Plan” for this aim. In this sense, “Raising Life Standards of Cities and Enabling Sustainable Development” was determined as the primary policy. Moreover, “Integrated Urban Development Strategy and Action Plan for Sustainable Urban Development” was prepared within scope of Program for Alignment with the EU Acquis. “ Integrated Urban Development Strategy and Action Plan 2010-2023”, with its short name Urban Development Strategy (KENTGES), comprises of settlement and urbanization; space, theme and extents of settlement and spatial planning within the principle of sustainability, make relations between spatial sectors within an integrated approach, enable adaptation with national basic policies. KENTGES is a national document which puts forward principles, strategies and actions for solution of structural problems of urbanization and providing healthy, balanced and habitable urban development; determines their practical principles and conveys them to an action program. In this paper, basic principles and practicability of the mentioned action plan which was prepared in order to enable sustainable urbanization in Turkey will be discussed.
