In recent decades, cities have grown organically and urban areas in a short time have been several times its original size and city development has been the forms of the individual components, without planning, uncoordinated that urban sprawl pattern is the main feature. Urban Smart Growth cities were developed for deal with problems of sprawl. The case study is Maragheh city. The research method is descriptive and analytical. In this paper, the capacity of Maragheh, using the development from within the main principles of smart growth is about the sprawl, is marked. Indexes such as population density, rate of open space, building quality, access and permeability, compressibility, etc. are used. Neighborhoods with using Analytical Hierarchy presses (AHP) to prioritize and ultimately the level was estimated for each of them. Results show that in 1392 the gross population density of 59.3 persons per hectare is which is considered very low density and On the other hand there is a lot of undeveloped land, 333 hectares, Uses of unconventional urban, and the average per capita level of infrastructure per person is 162.3 square meters. With this description, using the principles of smart growth and in particular, the principle of development from within and Suitable density, Building on wasteland and etc., sprawl can be prevented the sprawl.

Although population growth is the primary cause of urban sprawl, however sprawl has unreasonable adverse effects on natural and cultural environment which affects communities. Great efforts to overcome the negative effects of urban development has grown whose main strategy of "smart growth" as one of the strategies to combat "sprawl" and smart growth, urban development, in fact is an alternative to sprawl. The increasing pattern of development is one of the tools of smart growth and the realization of sustainable development is the obvious example. Shortage of land, natural and artificial barriers to horizontal expansion of cities, the locating of city on risky zones and faults, high costs of creating infrastructure services and utilities, as well as, some considerations related to environmental sustainability, development and originality of the old urban texture, reducing waste and energy investment, suitable transport network, all have led to the development pattern and the increasing investment in the urban context. By the horizontal spread and development of the city, sometimes the natural constraints face cost increases in utilities. If we add the number of aged residents tissue to the above number, probably about half of the population is poor under rough living conditions. Due to the increasing development and improvement of old tissue and the encouragement of low-density settlement in downtown areas, such problems could be solved. In this study to evaluate the potential synergies, the historical-cultural city of for has been selected and detailed design of the data is used Tabriz 6th district master plan. In order to evaluate the potential synergies have been determined between its model and them. Finally, with regard to the status quo and the outgoing model, this result was obtained that the increased development and changes in the texture of the surface will promote stability in the city and provide an appropriate physical structure.
