The environmental assessment of this project regarding urban sustainability indicators seems a tangible task to do. Accordingly, assessment of ecological effects of this project on Torghabe city, which is considered the capital of Khorasan Razavi province and the major eco-tourism centers nearby Mashhad metropolitan, is the main goal of this study. This analytical-descriptive study had been considered 4151 units of Mehr housing project in the mentioned city in terms of some important indicators such as water, soil, air and noise pollution. The results of this survey had been collected by means of observations and also questionnaires which were designed by evaluating environmental indicators and based on experts’ opinions and urban master impressions. Additionally, the AHP method was used for spatial analysis of environmental sustainability indicators. The results respectively revealed that the water pollution in the first level with 0.498 scale, vegetation change in the second level with 0.258 scale, soil pollution in the third level with 0.134 scale, air pollution in the fourth level with 0.076 scale, and voice pollution in the fifth level with 0.034 scale were the most dramatic effects of Mehr project on the environment.
