As the city developed and expanded to deal with environmental factors (climate and geomorpholic) and matters related to them will be greater. To the development of cities in a way is in the relationship with the dynamics and the dynamics of the natural environment. In dealing with these factors in the development of the city if you do not adhere to certain principles and essential tips the environment morphodinamic balance is destroyed and the most significant risks use and municipal facilities will be threaten in the city development. This study aimed to evaluate and determine the best direction for the physical development of Meshginshahr city natural based on a set of indicators such as Faults and geological structure, surface water, soil depth and texture, lines and land use to reduce the damage caused by natural hazards have been done by Using the weighted overlay model of the environment (GIS) and Swat. How to value in the optimal directions of the city development is classifiedin 4, the very poor, poor, fair good, and good levels. The results of studies, further sections of the city developed in relatively good land and and other parts of Meshginshahr, especially the marginal formed in unsuitable lands. Also part of the city that designed and built based on the previous plan are located in unsuitable lands and sometimes in very poor lands and limited parts of the city have been formed in the appropriate lands. Therefore, it is necessary to do the next city development in proper to relatively good lands to be avoided from risks and damages to the lives and property of the city and citizens living in the future. Thus according to the valuation was carried out, it is optimal to develop Meshginshahr city in the north and northwest and southwest portions and do all investments and projects, and programs to develop Meshginshahr in the directions mentioned.
