To evaluate smart growth and sustainable development in the region 72 indicators in 7 major criteria including socioeconomic and cultural-educational, health-medical, physical and land use, urban facilities and equipment, access and environmental were analyzed using TOPSIS model and Coefficient of Variation. The theoretical findings of this study indicates that smart growth strategy with emphasis on the prevention of urban creep and preserve existing neighborhoods, reduce travel time and traffic piles, encourage design based on human scale, community-based and necessity of public participation in urban planning, close to home and work, mixing land uses, urban design in keeping with the nature, development, environmental quality, ecosystem diversity and conservation of green and open spaces to encourage pedestrian activity and encourage dependency on private cars using the package of legal, financial and educational has opened new routes in the urban Planning.
